Misconceptions v.s. controversies

It seems that some distinction should be made between misconceptions (that people almost always stop believing when presented with evidence to the contrary) and controversies (where people usually refute evidence against their position with an argument of some sort) another way to state this would be that it is only a misconception if people believe it because they never heard otherwise if people have heard the evidence against their position and continue to believe it (however wrong that position might be)then it is a controversy or a fringe belief. —Preceding unsigned comment added by 97.116.83.19 (talk) 18:15, 6 January 2011 (UTC)

Vaccines and autism

While I realize I'm going to inject some controversy here; the claim that there's no biological basis for vaccines causing autism simply isn't true. The refutation of the vaccine/autism connection is typically based on population studies. There's solid biological evidence for a mechanism. Polymorphisms related to glutathione production are tremendously common in autistic children. Such a mutation wouldn't cause autism per se, but would make an adverse reaction to thimerosal more likely.

We compared levels of SOD, GSH-Px, and MDA in children with autism and controls. In children less than 6 years of age, levels of SOD, and GSH-Px were significantly lower in autistic children compared with their controls [1]

OBJECTIVES: The study objectives were to determine whether ... improvement is associated with increased plasma concentrations of glutathione (GSH) and an increased redox ratio of reduced glutathione to oxidized glutathione (GSH/GSSG), both of which have been previously identified to be low in children with autism.

[2]

Early post-natal toxicant administration to mice has been used to model autistic regression. To test the hypothesis that genetically altered mice might be more sensitive to toxicant exposure early in life, mice with a deletion of glutathione-S-transferaseM1 (GSTM1; a gene associated with increased risk of autism that codes for an enzyme involved in the management of toxicant-induced oxidative stress) and wild-type controls were exposed to valproic acid (VPA; a toxicant known to cause autism-like behavioral deficits that, in part, are mediated through oxidative stress)... VPA treatment caused significant increases in apoptosis in granule cells of the hippocampus and cerebellum. There was a genotype by treatment by sex interaction with wild-type females exhibiting significantly fewer apoptotic cells in these regions compared to all other groups. VPA treatment also resulted in long-lasting deficits in social behaviors and significant alterations in brain chemistry. VPA-treated GSTM1 knockout animals performed significantly fewer crawl-under behaviors compared to saline-treated knockout animals as well as wild-type controls receiving either treatment. Collectively, these studies indicate that VPA-treatment causes cerebellar and hippocampal apoptosis and that having the wild-type GSTM1 genotype may confer protection against VPA-induced neuronal death in female mice.

[3]

The severity of autism is associated with toxic metal body burden and red blood cell glutathione levels.

Multiple positive correlations were found between the severity of autism and the urinary excretion of toxic metals. Variations in the severity of autism measurements could be explained, in part, by regression analyses of urinary excretion of toxic metals before and after DMSA and the level of RBC glutathione (adjusted R(2) of 0.22-0.45, P < .005 in all cases). This study demonstrates a significant positive association between the severity of autism and the relative body burden of toxic metals.

[4]

De-novo mutations and advanced parental age as a risk factor for ASD also suggest a role for environment. Systemic and central nervous system pathophysiology, including oxidative stress, neuroinflammation, and mitochondrial dysfunction can be consistent with a role for environmental influence (e.g. from air pollution, organophosphates, heavy metals) in ASD, and some of the underlying biochemical disturbances (such as abnormalities in glutathione, a critical antioxidant and detoxifier) can be reversed by targeted nutritional interventions.

[5]

Reduced glutathione regenerating enzymes undergo developmental decline and sexual dimorphism in the rat cerebral cortex.

Oxidative stress during development may predispose humans to neurodegenerative disorders in old age. Moreover, numerous ailments of brain disproportionately affect one of the genders. We therefore hypothesized that, activities of enzymes regenerating and utilizing glutathione (GSH) show sexual dimorphism and developmental differences in rat brain. ...Our results showed that sexual maturation had an impact on activities of enzymes that regenerate and utilize GSH and rat female cortex had more anti-oxidant capacity. Moreover, age-related decline in the activities of these key enzymes were observed. Reduced glutathione and NADPH protects the brain from oxidative stress. Thus, our results may have implications for neurodegenerative disorders like Parkinson's disease and developmental disorders of brain like autism in which oxidative stress plays a key role.

[6]

Cellular and mitochondrial glutathione redox imbalance in lymphoblastoid cells derived from children with autism.

Lymphoblastoid cells (LCLs) derived from autistic children and unaffected controls were used to assess relative concentrations of reduced glutathione (GSH) and oxidized disulfide glutathione (GSSG) in cell extracts and isolated mitochondria as a measure of intracellular redox capacity. The results indicated that the GSH/GSSG redox ratio was decreased and percentage oxidized glutathione increased in both cytosol and mitochondria in the autism LCLs. Exposure to oxidative stress via the sulfhydryl reagent thimerosal resulted in a greater decrease in the GSH/GSSG ratio and increase in free radical generation in autism compared to control cells. Acute exposure to physiological levels of nitric oxide decreased mitochondrial membrane potential to a greater extent in the autism LCLs, although GSH/GSSG and ATP concentrations were similarly decreased in both cell lines. These results suggest that the autism LCLs exhibit a reduced glutathione reserve capacity in both cytosol and mitochondria that may compromise antioxidant defense and detoxification capacity under prooxidant conditions.

>That study only shows that people with autism have lower levels of glutathione, how exactly does that prove Vaccines cause autism? For that matter very few Vaccines use anything related to Mercury, so your statement that Vaccines verifiably cause Autism is wrong. -- —Preceding unsigned comment added by 122.109.101.9 (talk) 03:26, 6 January 2011 (UTC)

The passage which I removed from the page claimed there was no biological basis for vaccines to cause autism. Glutathione is primary in the removal of mercury from the body. Autistic people have demonstrably more numerous mutations in glutathione related systems. Thus, there is a biological mechanism for people with autism to be more susceptible to vaccines. This does not, nor is it an attempt to 'prove that vaccines cause autism.' It may very well be that people with autism would still have autism, but would be more likely to have adverse reactions to vaccination because of their chemical sensitivity. Primarily, this post explains the removal of incorrect information, namely that the page incorrectly claimed there was no biological mechanism by which vaccines could cause autism. Currently mercury (in the form of thimerosal) has been removed from nearly all vaccines, however prior to ~2000 that wasn't true. The association is therefore relevant to children 10 or older with autism. Further, you are not only misinterpreting what I wrote to be a claim that vaccines have been proven to cause autism, you are misinterpreting it to be a claim that autism is caused exclusively by vaccination.--Ryan W (talk) 10:21, 6 January 2011 (UTC)

Interestingly, there was a segment on the news this very morning mentioning that several of the authors on one of the prominent papers (unfortunately, I didn't catch which one) linking vaccines and autism had withdrawn their names from the paper and were accusing the primary author not only of being wrong but of deliberate fraud. Any scientific support for the view that vaccines can cause/exacerbate/have anything whatsoever to do with autism seems to be fast eroding. 68.105.72.35 (talk) 15:20, 6 January 2011 (UTC)

Discussion on this topic at the science ref desk.[8] Your citation that "most" scientists this-and-that is sufficient to keep it out of the article. If the scientists can't definitively agree on it, then it's not appropriate to state it as if it were a blanket truth. It could be stated with appropriate qualifications, which it was previously lacking. ←Baseball Bugs ^{What's up, Doc?} carrots→ 02:01, 2 December 2010 (UTC)

I think it's pretty clear that the misconception about humans and dinosaurs not interacting needs to be reworded. It's still true that humans never interacted with "classic" or stereotypical dinosaurs like t-rex and brontosaurus. If birds are to be considered as equivalent to dinosaurs, then the misconception needs to be written better than it was. ←Baseball Bugs ^{What's up, Doc?} carrots→ 02:30, 2 December 2010 (UTC)

Heh heh, good point. Birds may be regarded as living dinosaurs, but if they are, then humans and dinos have definitely lived at the same time since we both exist now. Our Dinosaur article uses the phrase "non-avian dinosaurs" to refer to "classic" dinos like t-rex. Maybe we could use it in this case to clarify the situation? Doc Tropics 05:53, 2 December 2010 (UTC)

On further review, I see that "Non-avian dinosaurs" is already used, but not until near the end of the paragraph. Would moving it up into the first sentence help resolve some of the confusion? Doc Tropics 06:05, 2 December 2010 (UTC)

As I just said at the science ref desk, I think we've got a misconception within a misconception. One is that early hominids interacted with "classic" (non-avian) dinosaurs. The other is that all dinosaurs went extinct at least 65 million years ago. ←Baseball Bugs ^{What's up, Doc?} carrots→ 15:11, 2 December 2010 (UTC)

Hi guys. This statement: "being an evolutionary descendant of dinosaurs is not the same thing as being a dinosaur" is utterly false under modern classification systems (or at least, the classification system currently used by 99.99% of paleontologists. In phylogenetic taxonomy, unlike old-fashioned, pre-evolutionary Linnaean taxonomy, groups are nested within one another rather than being split off into 'classes' etc. In this sense, the clade Aves is nested within the clade Dinosauria (which is in turn nested inside Archosauria, Reptilia, Amniota, Vertebrata, etc.). According to all modern experts in the field (save a vocal minority of about 2 researchers), birds are dinosaurs. I can even personally attest that there has been a very large, prominent banner with the words "Birds Are dinosaurs" hanging in the Saurischian Dinosaur Hall of the American Museum of Natural History, not exactly an institution of quackery, for the past 20 years. There are also dozens of sources from the giants of the field listed in Origin of Birds, Feathered dinosaurs, etc. if you want something citable. In short, Baseball Bugs is misinformed and/or following outdated information. MMartyniuk (talk) 00:10, 3 December 2010 (UTC)

That's not quite true. As was pointed out in the science ref desk, "dinosaur" used to mean one thing, and its definition was broadened to mean something else, but in general the public thinks of T-Rex and Brontosaurus as "dinosaurs", and birds as "birds". And as I say, this leaves us with a misconception within a misconception. The standard "fact" is "dinosaurs went extinct 65 million years ago". That's true of the "classic" dinosaurs, but not of the avian ancestors. So the misconception needs to either be re-worded or jettisoned altogether. ←Baseball Bugs ^{What's up, Doc?} carrots→ 01:00, 3 December 2010 (UTC)

Well, I was just responding to a request for clarification. I don't know what definition of "misconception" you guys are using. The fact is that in the past, "dinosaur" was a vague term that excluded birds but included certain extinct reptiles. It has since been given a formal definition where it includes a specific set of reptiles that happens to include birds within that set. This is in parallel with say, the definition of "planet" (note, not a 're-definition', as in both cases no formal definition existed in the first place). If you would say that it's a misconception that Pluto is a planet, than it is also a misconception that dinosaurs are extinct. If not, then it's not. Is it still a misconception if a definition changes and the general public doesn't know about the change? I think that's the central issue here, not whether or not birds are dinosaurs (they are, contra your initial posts asserting otherwise). MMartyniuk (talk) 01:35, 3 December 2010 (UTC)

The misconception is that humans interacted with "classic" dinosaurs such as T-Rex and Brontosaurus, and that misconception remains intact. In general, people don't think of birds as being dinosaurs, because they are not "terrible lizards", they are birds. As far as Pluto is concerned, that wouldn't qualify as a misconception, because Pluto did not change, only the scientists' designation for it did, just as they decided to redefine what a dinosaur is; which is why scientists get ridiculed for stuff like this. Of course there was a "formal definition" of what planets and dinosaurs were - look in any old dictionary. The asteroids used to be called "minor planets". This term "dwarf planet" is likewise an invention of scientists, but Pluto is still a "planet" by strict definition of what a "planet" is. ←Baseball Bugs ^{What's up, Doc?} carrots→ 01:52, 3 December 2010 (UTC)

By "formal definition" I meant a scientific one used by experts in the field, not the kind of vague, colloquial definitions given in dictionaries for scientific terms. (I actually have some popular kids books from the '70s which argue that there is no such thing as a "dinosaur to begin with, only a vague, informal term for certain unrelated prehistoric reptiles. The modern definition took over when it was recognized that classic dinosaurs actually do form a natural group. So it was as much a result of scientific discovery as changing definitions). Looking in a random dictionary right now, the definitions given there would make some "classic dinosaurs" true birds, since it defines "bird" only as "winged, egg-laying, warm blooded vertebrates." This describes Velociraptor as much as it does an ostrich. As for minor planets, the fact that different people were using the term planet in different ways at various times means that there were a variety of colloquial definitions, but no universally recognized formal one. Anyway, I agree with you that if it has to come down to an issue of semantics like this, it's probably not a common misconception. MMartyniuk (talk) 02:36, 3 December 2010 (UTC)

Scientists are notorious for changing their minds about things, so the statement "birds are dinosaurs" is not a "fact", it's merely the way one group is classifying things this week. ←Baseball Bugs ^{What's up, Doc?} carrots→ 18:39, 4 December 2010 (UTC)

Simply put: Birds are dinosaurs, by today's standards, but this need not be included in the misconception due to its confusing nature? —Preceding unsigned comment added by 72.187.99.79 (talk) 07:43, 5 December 2010 (UTC)

It's a fact if you simply use a full sentence. It is a fact that birds are dinosaurs in the most used phylogenetic model. Or cladistic model. Or whatever. That being the dominant model, saying it 'isn't a fact' is like saying "Earth being a planet isn't a fact." Well, in the relevant model, it is! In some model it may not be, but so what? —Preceding unsigned comment added by 72.187.99.79 (talk) 08:28, 5 December 2010 (UTC)

I would agree if someone wants to remove the bit about birds being dinosaurs. I only re-entered the edit four or six times, or whatever, because the argument against it was that 'birds aren't dinosaurs'. Which is wrong. But it is true that 'birds are dinosaurs' might not be really a necessary tidbit for this misconception. —Preceding unsigned comment added by 72.187.99.79 (talk) 08:32, 5 December 2010 (UTC)

Actually, the right way to say it might be, "Birds didn't used to be dinosaurs, but now they are." And if that seems like a joke, it is, but not for the reason you think. It's the scientists who are responsible for this shifting sand of definitions. ←Baseball Bugs ^{What's up, Doc?} carrots→ 13:26, 5 December 2010 (UTC)

Baseball Bugs, the nature of science is ongoing review when new data becomes available. The last thirty years has seen huge changes in how we classify organisms (cladistics) - we now know that birds are descended from dinosaurs, and that that means they are technically dinosaurs. Birds, dinosaurs (and crocodiles for that matter) share a more recent common ancestor (and are hence more closely related to each other) than other reptiles such as turtles, snakes and lizards. Hence they form a more natural group. I would add a final line "Ironically, birds are now considered to be dinosaurs by most scientists, so we are all coexisting with dinosaurs." once I find a nice consensus reference. Having a photo of the banner sounds cool. Casliber (talk · contribs) 23:59, 5 December 2010 (UTC)

Birds are dinosaurs. In the same sense in which humans are apes, apes are monkeys, and whales are fish. Don't worry, I'm not about to try to make those changes. TomS TDotO (talk) 14:06, 22 December 2010 (UTC)

I've stayed out of this debate but now feel compelled to jump in. Casliber, the sources occasionally use the phrase "are dinosaurs", but there is also a generous use of phrases such "descended from", including the idea that dinosaurs and birds descended from a common ancestor, which does not make birds equivalent to dinosaurs. There is enough doubt about the bold statement "birds are dinosaurs" that it should not be stated as such in the article. Mention the possibility, including common ancestry, but don't state "birds are dinosaurs" as if it is unquestioned fact. Cresix (talk) 15:39, 22 December 2010 (UTC)

"birds equivalent to dinosaurs"? "birds = dinosaurs"? Is there such a confusion about the statement that birds are dinosaurs? That "birds are dinosaurs" means that "dinosaurs are birds"? If there is such a confusion, then it counts as a common misconception, and there should be an explanation of that. "Tomatoes are fruit" does not mean that fruit are tomatoes. Maybe there should be an entry about cladistics, in which it is explained that a clade includes all the descendants of the last common ancestor (LCA) of all of the members of the clade. If "dinosaur" is a clade, and birds are the descendants of some dinosaurs, then that means that birds are descendants of their LCA, and birds are dinosaurs. Just as humans are the descendants of the LCA of chimps and gibbons (both of which are universally recognized as apes). Just as apes are the descendants of the LCA of titis and baboons (that is, monkeys). Just as whales are the descendants of the LCA of sharks and tunas (that is, fish). (Other examples of descendants of the LCA of fish are ostriches and anteaters.) TomS TDotO (talk) 16:31, 22 December 2010 (UTC)

Please Cresix, read about cladistics. And look at the sources. These museums do not make statements like this lightly. Each reference makes the statement "birds are dinosaurs" within it. Casliber (talk · contribs) 19:34, 22 December 2010 (UTC)

Despite your condescending suggestion, Casliber, I did read the sources. You are selectively citing parts of sources, overlooking (as I have already said) that the sources also make as much use of phrases such as "descended from" as they do "are dinosaurs". Certainly the possibility exists that birds are dinosaurs, but you are imposing an inflexible interpretation on a matter that is not universally acknowledged, even in the very sources that you cite. Cresix (talk) 18:59, 23 December 2010 (UTC)

It seems to me the problem here is just that there are clearly two senses of 'dinosaur' involved here. There is the scientific sense, which is rigorously defined, and in this sense birds are dinosaurs. There is a distinct, ordinary sense, which is not clearly defined, and in this sense birds are not dinosaurs. This is perfectly analogous to the term 'animal'. In its biological sense, humans are animals. In its ordinary sense, humans are not animals. (If you doubt the latter claim, try reporting child abuse to your local animal cruelty prevention organization.) Because there are two distinct senses of the same word, any revisions need to acknowledge explicitly that there are these two senses, and say unambiguously which is intended. MJM74 (talk) 20:08, 22 December 2010 (UTC)

ISTM that everybody is agreeing that there is a common misconception or two which call for explanations, and what better place to have those explanations? TomS TDotO (talk) 20:55, 22 December 2010 (UTC)

Whow, this is one of those problems even scientists themselves are not agreeing about. We are just having a nice discussion on this topic on one of the taxonomists list-serves. Anyway, the issue is that there are several paradigms used when we classify taxa. In the strict phylogenetic way, all extant species that originated from a single ancestor are preferably grouped together in a monophyletic group. If we do that, birds and dinosaurs are in the same group. A different way to look at it is from the perspective of changes, some critical characteristic. Here it gets fishy, because birds are traditionally defined on characteristics like having feathers, but feathered tetrapods have made taht a bit difficult and the current definition of birds is somewaht arbitrary set to Archeopteryx being the first bird. But if we ignore those details, birds have acquired some unique characteristics and for that reason should be considered a seprerate group outside of the dinosaurs. This would make the dinosaurs paraphyletic in the phylogenetic sense, but would be more representative for the crucial changes underpinning the group. Nowadays, there is a strong push in science towards forcing monophyletic groups in the phylogenetic context (especially by molecular phylogenetisists), but it is by no means the only voice (many more traditional taxonomists disagree). -- Kim van der Linde ^{at venus} 21:09, 22 December 2010 (UTC)

The nested definition idea seems suspect to me. if birds are dinosaurs because they share a common ancestor, doesn't that mean that mammals are reptiles (or amphibians, or fish) for the same reason? I can't see that "descended from a common ancestor" means "is the same as" Jimfbleak - talk to me? 09:24, 23 December 2010 (UTC)

But birds do not just "share a common ancestor" with dinosaurs. We share a common ancestor with dinosaurs, trees share a common ancestor with dinosaurs, crocs share a common ancestor with dinosaurs. Birds are nested inside dinosaurs, just as tyrannosaurids, ceratopsians, and sauropods are. (Follow the links in order to make any sense of things.) It's no different from dogs being nested inside mammals. And Velociraptor (or even Brachiosaurus) is more closely related to a house sparrow than to a Triceratops. Albertonykus (talk) 04:32, 24 December 2010 (UTC)

"Birds are dinosaurs" does not mean "birds are the same as dinosaurs." Some dinosaurs were not birds. And the same "problem" of cladistics applies with "reptiles" (including "turtles", "crocodiles", and "snakes" implies including "mammals" and "birds") and "fish" (including "tunas" and "sharks" implies including "reptiles").

Vomitorium redux

After reading the previous discussion on this talk page about vomitoria, I did a little source-hunting to see if I could nail down "misconception" and "common" sources (and convice myself that I'm not crazy and everyone else has heard this one too!). Here's what I came up with:

• Oxford Dictionaries entry for "vomitorium": "a place in which, according to popular misconception, the ancient Romans are supposed to have vomited during feasts to make room for more food".
• Google books preview for a book called "A Cabinet of Roman Curiosities: Strange Tales and Surprising Facts from the World's Greatest Empire": "There is a common misconception that rich Romans had a special room, a vomitorium, to which they withdrew to throw up so that they could continue eating. There is no evidence for such a room.", which goes on to define what a vomitorium actually was, in addition.

These both strike me as fairly reliable sources; I'd like to propose that we replace the vomitorium blurb in the article with the wording originally provided by IP 199.106.103.249, bulked up by my sources: In ancient Rome, there was no wide-spread practice of self-induced vomiting after meals, and Romans did not build rooms called vomitoria in which to purge themselves after a meal. Vomitoria were tunnels underneath the seats in their stadiums which allowed crowds entrance and exit.

Mediation

There is an outstanding request for mediation concerning this article. I would be willing to accept the role of mediator, but I have a couple of concerns. First of all, the request for mediation looks more like a request for support. That is not how mediation works. Secondly, the atmosphere on this talk page seems quite hostile and I see possible IP socking issues. Is this a serious request for mediation, or should I just close the case? -- Scjessey (talk) 18:32, 4 December 2010 (UTC)

How nice it was of the user to NOT notify us of that nonsense. As far as socking, he freely admits to using that IP, so that's not at issue. He does tend to show up and disappear, such as he did in mid-November, and also since about 3 days ago. The problem on this page is editors who run across something that has to do with a survey about misconceptions and then they present it as "fact". The wrangling is over trying to keep the page tight and neither endless nor dubious. The dinosaurs/birds issue is one. The point is it's being debated. The trouble with the user in question is that he doesn't understand that his posting something in an article doesn't mean he gets to own that posting. ←Baseball Bugs ^{What's up, Doc?} carrots→ 18:53, 4 December 2010 (UTC)

Hmmm. It doesn't sound like mediation is appropriate (or necessary) in this instance. I'll give it 24 hours for the requesting party to respond, but if I don't hear anything I'll close the case. -- Scjessey (talk) 19:11, 4 December 2010 (UTC)

Nor was I notified, and I'm directly named in the mediation request as a party to the dispute. This issue was discussed rather extensively on this talk page. This is an example of one user (TheThomas (talk · contribs)) trying to assert unilateral control over the consensus process repeatedly over a period of months and not accepting the fact that he does not form a consensus of one person. Both before and after requesting mediation, he restored the item with his "consensus of one". The first time he tried to do it "under the radar" editing as an anon and not leaving an edit summary. When called on that, he made the request for mediation. When that didn't get a response for a couple of weeks, he again restored the item with the edit summary "Added back in due to lack of consensus or reasoning for removal". Note also that some of this user's suggested additions to the article have been accepted with little discussion, so we have taken the time to consider his ideas and, when necessary, discuss. Cresix (talk) 21:00, 4 December 2010 (UTC)

There is two cases that I have repeatedly added sourced material (usually days apart), which has then been repeatedly reverted by Cresix or Baseball Bugs.

1) I go to the talk page, discuss the removal. I get no response for five days, then I add in the removed piece--"Added back in due to lack of consensus or reasoning for removal". That is my understanding of consensus by silence in WP:CON. If nobody has a reason for removal of material, then it is consensus by silence.WP:SILENCE

2) The second case in which I post material repeatedly (again, days apart) is when the complaint against my material is that the source is bad (broken link, not specific, not a strong enough study). In which case I go find a study which meets the reasonable requirement set by the objecting party, and reinsert the material. Which is my understanding of consensus.building consensus Both parties (myself and objector) agree that the article could use stronger supporting references, then I add the references after waiting for any other objections.

I have tried, multiple times, inserting new material directly into the discussion section--in order to skip the insert/delete/insert/delete phase. This has resulted in zero, zero, responses. So, I must put the material into the page to test whether these two will delete it. So far, my experience has been that these two will delete anything they have once removed--no matter how many times I meet their requests for better documentation of the appropriateness of my inserted statement.

The short version; these two are repeatedly deleting good, sourced information without reason, or having given a reasonable standard to meet, deleting after the standard is met. That is edit-warring, and it is bad for wikipedia. Effective discussion has ended, since no reason is given for repeatedly deleting material--besides the circular reason, 'no consensus for addition.' TheThomas (talk) 08:40, 5 December 2010 (UTC)72.187.99.79 (talk) 07:38, 5 December 2010 (UTC)

'Consensus for addition' is not policy of an unchallenged edit. It is the opposite of policy.Wikipedia:DRNC This page does not get its own policy because these two demand it.WP:CONLIMITED

Only when an edit is removed, and in the discussion or edit note, there is listed a reason for removal, which isn't addressed, is consensus needed. The edits I have repeatedly put in with more, and more, sources were not in need of consensus.Building Consensus If an issue was brought up, it was addressed, or the issue was dropped by me. If an issue was not brought up with the edit, I waited 5 days then re-entered the edit, per wikipedia policy.WP:SILENCE

Note: for the character of these edit wars. In this discussion section Baseball Bugs states that I warned him not to edit war after he repeatedly removed material. He feels he was in the right simply because he thinks what I put was " the blatant falsehood that 'birds are dinosaurs'." Apparently, not knowing much about dinosaurs, he feels he is the ultimate judge here. Despite me linking to the Birds article which I was very nearly quoting. The truth wasn't important to him, the quality of references weren't important. What was? His opinion, that's what.

This occurred again with the first iteration of another statement I have been trying to edit into this article. He started the discussion by simply saying, 'no that's wrong'. Without knowing a damned thing about the subject he feels he can flout peer-review, and professional opinions I cited [9]. At this point it has five separate references for one sentence. Not enough? Not if opinion is more important than fact. Having just two sentences in the conversation--one accusing me of being a shill for a corporation--he then baldly asserts "Yes, it's settled: It doesn't belong in the article." The conversation was between me and one other person(Cresix), no consensus whatsoever. Why is it settled? Cuz Bugs says so.

As for Cresix. He thinks I am bound by rules that he really doesn't pay attention to. Wikipedia:DRNC "Don't revert due to 'no consensus' ". He repeatedly says I can't enter things into this article without first having consensus. Guess who's consensus. Bug's and Cresix's. The only two people in the discussion channel. Bugs says no to everything he doesn't understand. With a three person vote, it will always be Cresix that decides the vote...this is not an excellent system. Ownership! Wikipedia policy states that "no consensus" for adding an edit is NOT a reason for keeping that edit out, except in highly refined pages, which this is not. Consensus is for removing material, but this bureaucrat missed that part, and repeats the circular reasoning, "No consensus to make any of the changes currently under discussion." Oddly enough, he usually doesn't even bother to claim a problem with an edit, just says there is no consensus.

As for the particular accusations : "We have a user who insists, despite lengthy talk page discussion, that he has a right to post a particular theory despite the lack of consensus to do so." -- I have no idea what this is referring to. Nearly everything I have posted (all with citations) has been immediately reverted. Often while displaying a lack of understanding in the appropriate field of knowledge. Note "Birds are dinosaurs."

"This user apparently thinks he constitutes a consensus of one person, despite being told repeatedly there is no such thing." --This is wrong. A consensus by silence is a consensus of one person. Which I have been clear about. If no one discusses any complaint about an edit for five days I put it in b/c that makes sense. "Of course, it is impractical to wait forever for affirmation: in the meantime then, sometimes it is best to assume that silence implies consensus." WP:SILENCE

"He first tried to restore contentious material "under the radar" by editing as an IP with no edit summary." --Yes...all edits that aren't declared as "Hey Cresix, I'm editing" are insidious...

Cresix claims, TheThomas gave a gratuitous warning "...to me after I reverted him one time." In fact, nearly all my (many, cited) edits were reverted by one of these two users.

I'm simply trying to make this article better by adding well-sourced material. Unfortunately, instead of this being a cooperative activity it has become a competitive one.TheThomas (talk) 12:28, 5 December 2010 (UTC)

Firstly, please try to follow the usual conventions for indenting comments. The above is confusing, and the problem is exacerbated by flipping between your account name and IP address. Secondly, it seems clear to me that the problem here is lack of editors. This is typical with "list of..." articles (may they all be damned) because they are so often subjective. Thirdly, the debate has descended into a series of terse comments of dubious good faith. If mediation is truly desired, I will be happy to help. That being said, I will primarily be involved in facilitating collegial discussion, during which I will expect everyone to behave like timid nuns and basically follow the tried-and-trusted approach of proposing changes on the talk page before attempting to implement them. -- Scjessey (talk) 17:01, 5 December 2010 (UTC)

FYI: This article has been a WP:BATTLEGROUND for at least a couple years. Things have actually died down significantly from its heyday. A Quest For Knowledge (talk) 17:06, 5 December 2010 (UTC)

Hi, AQFK! Thank you for the info. I will bear that in mind if mediation is accepted by the parties. -- Scjessey (talk) 17:11, 5 December 2010 (UTC)

Maybe locking down both the article page and the talk page for awhile might help. Like for 6 months. ←Baseball Bugs ^{What's up, Doc?} carrots→ 17:12, 5 December 2010 (UTC)

Oops, I think I might have given a false impression. If I am not mistaken, Bugs, Cresix and TheThomas are relatively new editors to the article. I was referring to past disputes with different editors. A Quest For Knowledge (talk) 17:17, 5 December 2010 (UTC)

I once gave a false impression. I tried doing Sylvester, and they told me I was Daffy.

I ran across this page a few months back, I don't recall exactly when; and there was indeed constant arguing, all going back to the attempt to keep the standards rigorous or you'd have every alleged "misconception" that was revealed by some researcher's survey or that someone remembered from childhood turning up here. ←Baseball Bugs ^{What's up, Doc?} carrots→ 17:22, 5 December 2010 (UTC)

Just to clarify, I have followed this article for about four years. I did some minor editing originally as an anon. Then after registering I became more active. I've witnessed a lot of the battles. Cresix (talk) 17:25, 5 December 2010 (UTC)

@AQFK - It's okay. I read it as an historical issue, rather than something current. -- Scjessey (talk) 17:21, 5 December 2010 (UTC)

@Bugs - That seems a teeny bit extreme, akin to "I say we take off and nuke the entire site from orbit." -- Scjessey (talk) 17:21, 5 December 2010 (UTC)

Hence the "maybe". ←Baseball Bugs ^{What's up, Doc?} carrots→ 17:27, 5 December 2010 (UTC)

Thanks, Scjessey. I'll simply comment that TheThomas has provided no new information in this section. The fundamental issue is whether the item that TheThomas wishes to add is a "common" misconception. In my opinion (and I believe Baseball Bugs will agree) it is not a common misconception, and TheThomas has not provided adequate evidence that it is a common misconception. This is a frequent issue for this page: There are millions of misconceptions. Are all of them "common" misconceptions? Some misconceptions are held by a few people ("the earth is flat"). Some are held by a group of people with enough knowledge of the subject to even have a misconception (the behavior of subatomic particles). Some are held by a broad range of people, and those might be considered common. Sometimes an item is added after an editor finds clear evidence that the misconception is common; for example, see the excellent work above by keɪɑtɪk flʌfi regarding Roman vomitoria. That issue was debated back and forth as to whether it is a common misconception; then keɪɑtɪk flʌfi did the research and found very good sources supporting that it is common. Even then, keɪɑtɪk flʌfi was thoughtful enough to get others' opinions before adding the item. Without unequivocal sourcing that the misconception is common, items are sometimes added by consensus that the misconception is common. I don't believe TheThomas has provided that unequivocal sourcing, and there is no consensus to add the item. Thanks. Cresix (talk) 17:19, 5 December 2010 (UTC)

Good summary. ←Baseball Bugs ^{What's up, Doc?} carrots→ 17:24, 5 December 2010 (UTC)

(after ec) - I would argue that there is no consensus not to add the item either. A meaningful consensus is hard to obtain with so few editors. Perhaps a Request for Comment would be more useful? It would bring in extra eyes on this matter. -- Scjessey (talk) 17:25, 5 December 2010 (UTC)

Anyone, of course, can post an RfC. I would urge that if it is done, in the spirit of neutrality, the explanation should include a clear distinction between sourcing that an item is true (e.g., the earth is not flat) and sourcing that it is a common misconception. Cresix (talk) 17:28, 5 December 2010 (UTC)

BTW, as for no consensus not to add the item, that certainly is true, but until there is a consensus, the burden of proof is on the editor wishing to add or restore the item. Cresix (talk) 17:32, 5 December 2010 (UTC)

You're right, and that's the crux of the current issue. Thomas and his IP alter ego think that if they read some magazine article that claims that (1) this is a common belief and (2) my survey indicates otherwise; that somehow it qualifies for this wikipedia article, without discussion. Wrong. ←Baseball Bugs ^{What's up, Doc?} carrots→ 17:36, 5 December 2010 (UTC)

With respect to WP:BURDEN, that is indeed correct; however, my purpose as mediator is to mediate between parties, and part of that is to make sure all reasonable points of view are considered. While I have my own feelings on the matter, I will not be taking sides. I would like to help parties come to a mutual agreement by promoting reasonable discussion and mutual respect. -- Scjessey (talk) 17:46, 5 December 2010 (UTC)

Understood, and thanks for your efforts. Cresix (talk) 17:50, 5 December 2010 (UTC)

If it's simply a question of sourcing, WP:RSN should settle the matter in a couple of days. A Quest For Knowledge (talk) 17:41, 5 December 2010 (UTC)

RSN may be helpful, but again, let's make distinction. An item can be reliably sourced as true ("the earth is not flat"), but that is not equivalent to being reliably sourced that it is a common misconception. Cresix (talk) 17:44, 5 December 2010 (UTC)

(ec)The tricky part is this article's two-pronged requirement of a "fact" being both a commonly held belief and being untrue. One author claiming that something is both a commonly held belief and that his survey proves otherwise, is nowhere near sufficient. The "commonly held" part needs to be broadly demonstrated to be "commonly" believed; and the "untrue" part needs to be broadly demonstrated to be untrue. One guy taking a survey demonstrates neither. ←Baseball Bugs ^{What's up, Doc?} carrots→ 17:46, 5 December 2010 (UTC)

If an editor is combining two sources to state a conclusion not reached by either, then it's a violation of WP:SYN. A Quest For Knowledge (talk) 17:54, 5 December 2010 (UTC)

Certainly, but it's not exactly that, in this case. It's finding a magazine article somewhere and concluding that that one article is the truth and therefore it qualifies, without looking into other studies that might demonstrate otherwise... or looking into studies of those studies, which would take away the "primary source" aspect of it, while supporting the "widely held" requirement and possibly the "untrue" requirement. I say "possibly" because surveys are notoriously suspect for being worded in such a way to prove the researcher's point. I've said before, I know exactly where I was on 9/11/01 and 11/22/63 when I heard the news, and no survey in the world can prove otherwise. ←Baseball Bugs ^{What's up, Doc?} carrots→ 17:56, 5 December 2010 (UTC)

It would be helpful if the proposed text and associated sources could be represented in a new section below. -- Scjessey (talk) 18:04, 5 December 2010 (UTC)

See below. ←Baseball Bugs ^{What's up, Doc?} carrots→ 18:15, 5 December 2010 (UTC)

Thanks for that. I must be missing something, because I'm having a hard time believing flashbulb memories are a misconception at all, let alone a common one. -- Scjessey (talk) 18:25, 5 December 2010 (UTC)

To some extent, I believe you are correct. I believe this particular "misconception" falls into the group I described above as held only by people who have enough knowledge to even have a misconception. It may be a misconception among some with knowledge of memory research (or those who think they have that knowledge), but most people have never heard of it. Cresix (talk) 18:29, 5 December 2010 (UTC)

The alleged misconception is that people don't remember things as well as they think they do. That's hardly a news flash, as there is no end of conflicting testimony of eyewitnesses even right after an event. And you're right, this "flash memory" business is an obscure term. This vaguely reminds me of something from a few months back about how Louis Armstrong supposedly had a different birthdate than was "commonly" thought. Trouble is, the average citizen nowadays barely knows who Louis Armstrong was, never mind what his birthday was. That one, obviously, was kept out. ←Baseball Bugs ^{What's up, Doc?} carrots→ 21:57, 5 December 2010 (UTC)

And again, the premise is unprovable anyway. I can tell you precisely where I was and what I said when I first learned of JFK and 9/11 and the Shuttle explosion, but I haven't a clue what I had for lunch on those particular days. Some things stick with you and some don't. ←Baseball Bugs ^{What's up, Doc?} carrots→ 22:01, 5 December 2010 (UTC)

Things have gone quiet. Will one of you file an RfC over this issue, or shall I just close the medcab case and exit stage left? -- Scjessey (talk) 16:00, 7 December 2010 (UTC)

Those two options are not mutually exclusive, of course. I suggest closing if you see no need for mediation. Any editor can post an RfC at any time. Thanks for you help. Cresix (talk) 17:24, 7 December 2010 (UTC)

This is so sad. Cresix just repeats "there is no consensus" while bugs makes up some nonsense about citing one magazine article. The one statement has five citations, and no consensus is not a reason. It is nonsense to say that hasn't met the burden of proof, it has several citations which say it is a common misconception, several which say it is common, and several which say it is a misconception. But, at least spitting out nonsense is better than the edit warring you two have been doing--not even having claimed a reason to support your actions. I don't care to spend an infinite amount of time discussing this topic, so I probably won't attempt to find a six, seventh, and eighth citation for the bloody-fucking obvious.72.187.199.192 (talk) 10:28, 11 December 2010 (UTC)

"...the premise is unprovable anyway." You've repeatedly said things like this (scientifically and logically illiterate, or nearly so) about this, and other, edits I've made. I want you to consider that scientists were the ones to state that 'flashbulb memories aren't more accurate'. It wasn't me. What you are citing is your opinion of how accurate your memory is. The facts say that memory is no more accurate than other memories you have. Note: forgetting what you ate that day has nothing to do with this discussion. It is a discussion of accuracies of memories, not retention of memories.72.187.199.192 (talk) 10:28, 11 December 2010 (UTC)

Basically, I don't think you should be doing much more than editing when it comes to topics you don't understand. I understand your need to tamper, go ahead, but if you've never learned a significant amount about a topic, please don't remove/revert it. Note: In the "Birds are Dinosaurs" discussion we had to get a professional to specifically tell you that you were completely wrong...then you argued with him. 72.187.199.192 (talk) 10:28, 11 December 2010 (UTC)

The point of my "There is two cases that I have repeatedly added sourced material..." material up top was to point out that you were both consistently breaking policy to revert my material. The fact that you feel that 'adds nothing to the discussion' disgusts me. I normally wouldn't even think to explain why breaking policy repeatedly is bad. But, apparently you two need that done. When you break policy you undo what is good and great about wikipedia, and degrade it. Doing harm to a great thing is bad, it means you are foul and that the rest of us must undo your harm rather than enjoy wikipedia.72.187.199.192 (talk) 10:28, 11 December 2010 (UTC) —Preceding unsigned comment added by 72.187.199.192 (talk) 10:08, 11 December 2010 (UTC)

I'm not foul at all. In fact, I went into the gap for extra bases. :) ←Baseball Bugs ^{What's up, Doc?} carrots→ 21:48, 14 December 2010 (UTC)

TheThomas' edit

• It is a common misconception that some particularly emotional events (9/11, Challenger explosion) cause memories which are stronger (Flashbulb memory), and more reliable than normal memories. In fact, the details of any long-held memory are similarly very untrustworthy.

That sounds like a content fork, but it does give me an idea. Maybe there could be a separate article (again, at risk of it being endless) that examines the truth or falsehood of "well-known sayings". For example, "Lightning never strikes the same place twice." Obviously false, but it could be taken as a metaphor equivalent to "Opportunity only knocks once." "Water finds its level." Probably true. "Criminals always return to the scene of the crime." It only takes one exception to "prove" that one false, but a more interesting result would be if there is any reliable info on what percentage of criminals return to the scene of the crime, assuming they're even able to. ←Baseball Bugs ^{What's up, Doc?} carrots→ 17:53, 5 December 2010 (UTC)

French fries

I'm sure if the average American were asked which country originated French fries, they would look at the questioner as if he had just asked what color the White House is. The attempt by some to rename them "Freedom fries" due to political issues with France speaks to the core assumption that they're of French origin. In France itself, these kinds of fried potatoes are called "fried potatoes" or simply "fries", which also has the the unfortunate side effect to a visitor (such as I was) of reinforcing the assumption that they're French, because why would the French bother to call them "French" fries? I recall many years ago when Harry Reasoner did a special called "An Essay on Doors". The only specific thing I remember from that program are his comment, "French doors are about as French as French fries - which aren't!" However, sourcing is needed. :) ←Baseball Bugs ^{What's up, Doc?} carrots→ 23:33, 17 December 2010 (UTC)

I have a little different perspective on this. I suspect that most Americans perceive the name of the food as "frenchfries"; to them, it's just a name with no connotation of national origin. I think if they have a surprised look when asked which country originated "frenchfries", it would be the same look you would get if you asked for the country of origin for "hashbrowns" or "potato salad". Now if you emphasized the word "French", there might be a pause followed by "Uh ... I guess ... France??". But maybe I've just been hanging around people who don't think very deeply. :) Cresix (talk) 23:57, 17 December 2010 (UTC)

I think Reasoner's comment subtly points out something. There are likely plenty of objects which have false labels. The public uses those false labels frequently and ignorantly. But does it matter enough to add it to a "misconceptions" article? Actually, the attempt to label them "Freedom fries" speaks directly to such a misconception. But it would be tough to prove that the average citizen really knows or cares what country these fries actually originated from. A parallel I can think of is chop suey, which is commonly assumed to be a Chinese dish, but supposedly was invented by a restaurant owner in Chinatown, San Francisco, which means the dish is not exactly "Chinese", but more like "American-Chinese". But it tastes the same either way. :) ←Baseball Bugs ^{What's up, Doc?} carrots→ 00:23, 18 December 2010 (UTC)

Humans, dinosaurs and birds, oh my

OK, I've stayed out of the bird/dinosaur issue, but having just read the item,[11] it's confusing and appears to contradict itself. The item needs to be clearly explained or removed. Or just remove the last sentence. The last sentence is probably a violation of WP:SYN anyway. A Quest For Knowledge (talk) 19:41, 22 December 2010 (UTC)

We now have discussion on this topic going on on two sperate places on this page. What is synthesis about it? Birds = dinosaurs in the sources provided. I guess you could take out the word "conversely", is that what you mean? Actually a better idea is to change the misconception to "Dinosaurs are extinct. They are not. Birds are dinosaurs"Casliber (talk · contribs) 20:07, 22 December 2010 (UTC)

Maybe it's not WP:SYN, but the last three sources aren't about this common misconception. I think the problem is as you said, there are (at least) two different defintions of the word 'dinosaur' but our article doesn't explain this. Just axe the final sentence and it's fine. A Quest For Knowledge (talk) 20:15, 22 December 2010 (UTC)

A week or so ago, it stated that the last non-avian dinosaur went extinct 65 million years ago. I thought that was a nice, concise way to say it. So what happened? ←Baseball Bugs ^{What's up, Doc?} carrots→ 20:27, 22 December 2010 (UTC)

{EC}I dissected a frog once. I think you're being too clever for your own good. When most people think of dinosours, they're thinking tyrannosaurus rex, brontosaurus, pterodactyl, etc. See this. In fact, dictionary.reference.com defines dinosaur as "any chiefly terrestrial, herbivorous or carnivorous reptile of the extinct orders Saurischia and Ornithischia, from the Mesozoic Era, certain species of which are the largest known land animals."[12] If you want to correct the common misconception that there are no living descendents of dinosaurs, I suggest you create a separate item. A Quest For Knowledge (talk) 20:37, 22 December 2010 (UTC)

Seriously, I don't see anyone disputing the misconception (that humans existed in the eras in question), all I see is a debate about wording which looks increasingly pedantic. I'm sure this is a relevant debate somewhere, but's not all that relevant on this page. Hairhorn (talk) 20:43, 22 December 2010 (UTC)

The assertion that "birds are dinosaurs" is not a "fact", it's this week's classification by scientists who think they own the English language. The simple wording that was there a week ago was just fine. The current version is an attempt to browbeat the public with the scientists' current definition of dinosaurs, and it's not appropriate. It's pedantic, as you say. The animals did not change, only science changed its definitions. Like when they haughtily declared that Pluto was no longer a planet. ←Baseball Bugs ^{What's up, Doc?} carrots→ 20:45, 22 December 2010 (UTC)

It is a fact. It's not this week's current definition but the culmination of 150 years' worth of investigation. The more fossils are found indicating a great many dinosaurs had feather-like structures as well as evidence for their warm-bloodedness, shows how wrong earlier conceptions were. Anyway, BB, beyond that the wording reflects the sources. Wording something as "descended from" implies exclusion, which is in error and conflicts with the sources.

I'm not going to get involved (at present) with your discussion, but will just comment on your (Casliber's) statement, which contains a logical error: "Wording something as "descended from" implies exclusion,..." No, "descended from" implies" "descended from", not exclusion. It can still be inclusive and definitely implies relationship, not exclusion. -- Brangifer (talk) 23:12, 22 December 2010 (UTC)

The only "fact" is that scientists co-opted the term and assigned their own meaning to it and expect the public to kiss up to it. In any case, the wording a week ago was fine, and somebody screwed with it. ←Baseball Bugs ^{What's up, Doc?} carrots→ 23:03, 22 December 2010 (UTC)

@BullRangifer, there is strict wording (i.e. the sentence makes no comment on inclusiveness), and there is implication. But okay, I'll conced the point. The next issue then is that the statement which uses "birds are descended from dinosaurs" without saying "birds are dinosaurs" is cherry-picking material from the sources and potentially misleading by omission. Casliber (talk · contribs) 00:10, 23 December 2010 (UTC)

We could resolve this issue nicely by deleting everything from "The issue is complicated..." and onwards. It really does "complicate" the picture and really isn't part of the whole point. It's only an issue for pedants. It sidetracks and detracts from the main point....humans and dinosaurs didn't exist at the same time. That's the point and we should just stick to it.

A Quest for Knowledge, these arguments aren't about numerical advantages.

Casliber (talk · contribs) 20:20, 23 December 2010 (UTC)

That's not the point here. Sticking to the main and only point of that entry ("humans not coexisting with dinosaurs") is what counts. The existing reference documents the matter quite well. Was there anything in the refs that were removed with the other content that shed light on the point here, or were they about the other matters that sidetracked the whole matter? If there were any of them that were relevant to the "humans not coexisting with dinosaurs" matter, then you are more than welcome to restore them at the appropriate spot(s). Otherwise the idea of starting another section about birds=dinosaurs is still open. If you can find good sources without using any OR or SYNTH, then go for it!

Carrots improving eyesight

I was wondering if we should add an item about carrots improving eyesight. This was propaganda from World War II to explain why the Royal Air Force was so successful in fighting the Luftwaffe. Germans didn't understand the significance of radar so the British came up with a plausible explanation about carrots improving their pilots' eyesight. I haven't looked for any sources yet. I wanted to get some feedback first. A Quest For Knowledge (talk) 22:38, 4 January 2011 (UTC)

If you can find reliable sourcing that currently it is a common misconception, it might be possible (I'd suggest posting the sources here first). A misconception from 65 years ago may not be very common today. For example, back then many people where I lived thought someone who is slender was unhealthy and needed to get some "meat on his bones" by eating lots of red meat. My personal opinion is that the carrot idea probably is not very widespread these days. But if you want to dig up some sources, that would be an interesting one.

The real misconception here is failing to understand the fact that the Germans in WWII knew exactly what radar was, and in fact had such powerful portable radar systems that they were in a constant capabilities and countermeasures race with the Allies on all fronts (in which low tech chaff, or strips of aluminum foil, became the most tactically significant development on both sides.) 71.198.176.22 (talk) 08:59, 6 January 2011 (UTC)

Vinegar

Vinegar has been used to fight infections since Hippocrates, who lived between 460-377 BC, prescribed it for curing persistent coughs. As a result, vinegar is popularly believed to be effective against infections. While vinegar can be an effective antibacterial cleaning agent on hard surfaces such as washroom tiles and countertops,[28] studies show that vinegar – whether taken internally or applied topically – is not effective against infections, lice,[29] or warts.[30]~ 72.187.199.192 (talk) ~ —Preceding undated comment added 04:01, 5 January 2011 (UTC).

{{edit semi-protected}} under "human body"

• Alcohol does not in fact make one warmer. The reason brandy and other such drinks create the sensation of warmth is that they cause blood vessels to dilate and stimulate nerve endings near the surface of the skin with an influx of warm blood. This actually results in making the core body temperature colder, as it allows for easier heat exchange with the cold external environment.

I don't think the source is any good... The argument is, that if it does grow back thickler, coarser or longer, bald people could shave and get their hair back. By that argumentation you can say, that if caffeine makes you more awake, dead people could drink it and wake up! You have to have some experimental evidence to back it up! Not some hair-expert comparing hair and bamboo. I am sure that there is some scientific articles on the internet, so why not refer to them insted? Btw I haven't found any evidence that shaved hair doesn't grow back quicker... But then again, that isn't what is discussed here;) --130.225.29.254 (talk) 09:54, 5 January 2011 (UTC)

A science show in Australia did an episode on this a while back. They took photographs of a particular patch of skin and counted the number of hairs as well as measuring their overall length. They shaved the patch multiple times and retook the photographs. There was no change in number of hairs, hair length or hair colour. They went on to give the same explanation that is covered in this article and I think they might have even quoted some more reliable scientific studies. I'm sure that someone more interested that me can dredge up the name of the show. --Spuzzdawg (talk) 10:47, 5 January 2011 (UTC)

This entry is contradictory: "hair that has never been cut has a tapered end, whereas, after cutting, there is no taper. Thus, it appears thicker..." Something that is tapered is on average (over the its length) thinner than something that is not tapered. Therefore, this states that shaved-and-regrown hair is thicker than unshaved hair. Finishing the sentence from the article "... and feels coarser due to the sharper, unworn edges." Concerning one's perception of his hair, it's the feeling of coarseness that matters and not the microscopic coarseness. This again affirms that the regrown hair is in someway different from the unshaved hair, and in such away as to conform to the expectations of the "misconception." Likewise: "Hair can also appear darker after it grows back because hair that has never been cut is often lighter due to sun exposure." This suffers from bad writing. The hair doesn't "appear darker"; as stated by the author, it actually is darker than unshaved hair which has lightened from sun exposure.

Maybe the misconception is that "Shaved hair growing back coarser and darker is a misconception" ... —Preceding unsigned comment added by 98.114.27.182 (talk) 22:56, 5 January 2011 (UTC)

The previous commenter stated the case much more elegantly than I did originally. The entry, as listed, actually explains why shaved hair is, in fact, thicker (by virtue of not having a tapered end), coarser (by virtue of having a sharp, unworn edge not present on unshaven hair), and darker (by virtue of not being sun-bleached). I did not submit an edit because it simply needs to be removed. —Preceding unsigned comment added by 76.105.127.48 (talk) 05:34, 7 January 2011 (UTC)

Metal in Microwave Ovens

The citation titled "Is it Dangerous to Put Metal in a Microwave?" (http://www.wisegeek.com/is-it-dangerous-to-put-metal-in-a-microwave.htm) is an unsourced opinion in a blog. Does anyone have a citation to a reliable source to back up claim the that metal in a microwave oven can damage the magnetron by causing an impedance mismatch? An empty oven chamber has a nearly perfect impedance mismatch (basic physics; a perfect impedance match means maximum power to the load, and the walls and air of the empty chamber do not get hot, meaning very little power has been transferred, thus a nearly perfect impedance mismatch), yet microwave ovens survive that case just fine. Also, various types of automatic load impedance matching in microwave ovens have been around for years. See United States Patent 5512736 for one of many examples.

Although it would be original research and thus not usable as the Basis for a Wikipedia article, I would be most interested if anyone has ever burned out the magnetron in a microwave oven by putting metal inside of it. Where are the piles of burned out microwave ovens? Guy Macon 08:05, 5 January 2011 (UTC)

The microwave oven article states, "Another hazard is the resonance of the magnetron tube itself. If the microwave is run without an object to absorb the radiation, a standing wave will form. The energy is reflected back and forth between the tube and the cooking chamber. This may cause the tube to 'cook' itself and burn out. Thus dehydrated food, or food wrapped in metal which does not arc, is problematic without being an obvious fire hazard." This suggests that you are right, an empty microwave is a near perfect mismatch and suffers high VSWR. From this description, I imagine that the magnetron itself absorbs most of the energy. While magnetrons may not appear to suffer any damage from this I wouldn't be surprised if magnetrons were actually significantly damaged and their life expectancy significantly decreased from such an action. My extremely limited experience with high power radar magnetrons suggests to me that magnetrons are very touchy. Their spectral and power output can be significantly affected by aberrations within the tube and temperature. Heating and general use slowly change the internal dimensions and eventually the thing stops working. I wouldn't find it hard to believe that a high VSWR would exacerbate this process. I imagine that it is far more likely that the user believes the magnetron has been unaffected because the microwave continues to cook food. Of course, all of this is pure speculation. If you decide to conduct an experiment for yourself, make sure you pass on the results. --Spuzzdawg (talk) 11:12, 5 January 2011 (UTC)

I have done a bit of work with both radar and microwave magnetrons. The difference is a lot like the difference between a fine Swiss watch and a sundial. The radar is a precision instrument that puts out a precise beam at a precise frequency, while the microwave oven just has to spray a broad beam of microwaves into the cooking chamber with no particular effort to control the exact frequency.

Alas, the microwave oven article also has a problem with citations to reliable sources, as can be seen by the "This section needs additional citations for verification" tag. Somehow, though, having unsourced and unproven claims about microwave ovens in the list of common misconceptions article seems especially wrong. I am going to hold off until the latest storm of edits caused by the mention on XKCD dies down, and then, if nobody has come up with a reliable source, I will fix the page.

I also question the oft-repeated claim that the reflected energy heats the magnetron. Looking at the various patents that have been issued for microwave ovens, it seems much more likely that the oven lowers the power output and changes the impedance matching to compensate for the mismatch. Once again going back to basic physics, the proof one way or the other would be to find a reliable source giving us magnetron temperature readings with and without food in the chamber.

Another potential issue is that, in the case of consumer products, you cannot count upon the manufacturers recommendations being accurate. Such recommendations are usually written by the legal department, not the engineering department. Thus we see white 100% cotton sheets with "dry clean only" instructions an Q-Tips with instructions saying not to use then to clean your ears. Guy Macon 16:30, 5 January 2011 (UTC)

That source is totally unusable by our standards. The instructions from manufacturers of microwave ovens would be acceptable.

There is also another matter that seems to be ignored. Focusing on damage to the magnetron tube is only one problem. Just as with a shortwave diathermy machine Metal can quickly get very hot and damage things in the oven or the oven itself. If the writer of that blog article is correct, there are apparently ways to use the heat created to an advantage. It just as to be properly shaped and designed for the purpose. -- Brangifer (talk) 16:01, 5 January 2011 (UTC)

I agree that the blog is unusable by Wikipedia standards, so I deleted the citation and added a citation needed tag. I don't agree that instructions from manufacturers of microwave ovens would in all cases be be acceptable; see above for my reasoning. I think the issue of metal getting hot and damaging the oven (or your fingers!) can be addressed by expanding the part where it talks about arcing, so I will go and try to fix that. Guy Macon 17:05, 5 January 2011 (UTC)

Dumb question in general here. But the title of this article is List of Common Misconceptions. Now, what is the common misconception in this case? The way I've been familiar with this is "Don't put metal in the microwave because it might damage [the oven]". How is this a misconception? This sounds like saying "It's a misconception that you need to look both ways before crossing the road, because in some cases the road might be closed to automobile traffic". If on the other hand putting any common household metal object (fork, bowl, pot) in any commonly existing microwave never resulted in any damage to either object or oven, then I might agree that it was a misconception that "putting metal in microwaves is bad", but as it stands it seems more like a technicality that gets around this fact. I suggest this entry is removed from the list. Thoughts? -Popoi (talk) 16:21, 5 January 2011 (UTC)

The common misconception is that it is always dangerous to put anything metal in a microwave. The article should reflect that misconception. We know that sometimes it is a danger (arcing sets a bowl of popcorn on fire, the popcorn fire sets the plastic parts found in some microwave ovens on fire) and we know that sometimes it isn't (food containers containing metal that are designed for microwave use), so "it is always dangerous to put anything metal in a microwave" is indeed a misconception. As to whether it is a widely held misconception, every entry on this page raises that question, with no good way to get an answer from a reliable source. Personal experience is no help; you may live in a region that does not have a misconception widely held elsewhere. Guy Macon 16:58, 5 January 2011 (UTC)

Right, that's just my problem. (A) We are trying to call it a misconception i.e. completely false, when it is not always false. Putting aluminum foil in a microwave might cause a fire - ergo, putting metal in a microwave can be dangerous. (B) We're trying to narrow the definition of the misconception to "Putting any metal object in any type of microwave oven will always be dangerous" -- but that is not the way the "saying" goes. Show me the money! 1) Is there research that this is a common misconception? 2) Is the misconception always stated the same way? I think we are splitting hairs here, and again "there is a common misconception that you need to look both ways before crossing a road. some roads are not open to automobile traffic and it is completely safe to cross without looking both ways" --Popoi (talk) 17:27, 5 January 2011 (UTC)

I repeat, as to whether it is a widely held misconception, every entry on this page raises that "Is there research that this is a common misconception?" question, with no good way to get an answer from a reliable source. Personal experience such as asserting "that is not the way the 'saying' goes" is no help; you may live in a region that does not have a misconception widely held elsewhere. If you want to trade personal experiences, my mother, one former employer and a couple of friends all told me that any metal in any microwave will burn out the microwave's electronics. Not start a fire; burn out the electronics. That's the commonly held misconception as I heard it, which of course proves nothing. I might as well assert without evidence that that is the way the 'saying' goes. That, like your assertion ("that is not the way the 'saying' goes") are original research and unsourced material, and thus not acceptable as Wikipedia citations. Guy Macon 21:02, 5 January 2011 (UTC)

Believe it or not, there actually are entries in the article with sources that the misconception is common. A few others were settled by consensus. Feel free to challenge any that are not source or were not settled by consensus. But the argument that "other stuff exists" is not a valid one for adding unsourced information. Cresix (talk) 21:13, 5 January 2011 (UTC)

Regardless of all the assertions of this and that, this is the only misconception that doesn't actually state what the misconception is. Its really quite confusing, I had to read the above comments to understand what was going on. So you could rewrite it from scratch so that it actually makes sense Guy Macon (its currently suffering from "too many authors syndrome" for sure). Personally I'd just remove it. --eean (talk) 03:06, 6 January 2011 (UTC)

The issue here is not whether blood is ever blue, but whether it is a common misconception. Please look at the archives. The idea of blue blood has been rejected as a common misconception several times on the talk page. As just a informal illustration, almost no one is shocked, surprised, or even a little puzzled when they always see red blood if they have a cut. Cresix (talk) 15:21, 5 January 2011 (UTC)

I have been told by several people that they believe the misconception that blood can be blue. The reason that you don't see blue blood from a cut is that the blood comes into contact with air, and air is oxygen (note that is also a misconception). Sorry I don't have a source, but I'm sure someone could find one. 173.164.86.190 (talk) 18:19, 5 January 2011 (UTC)

Once again, please read the archives, where this issue has been discussed several times. The fact that you "have been told by several people that they believe the misconception that blood can be blue" does not qualify as a reliable source. If you're "sure someone could find" a source, you need to be the "someone" who finds its. I have been in the healthcare profession for over forty years and have never met one person who thought that blood can be blue or who was surprised that it is red.

Heat lost through head

"Although it is commonly believed that most body heat is lost through a person's head, this is not correct. The head loses as much heat as any other part of the body." This is only correct if one does not count breathing as heat loss through the head (incl. heat carried away by evaporated water in the breath), which is IMHO quite misleading. The citation does not address this issue at all. 81.182.216.151 (talk) 08:53, 5 January 2011 (UTC)

The sentence needs to be changed regardless. "loses as much heat" implies that the misconception is that one might mistakenly believe it loses less heat. "loses no more heat" would be a better wording, though I think it's wrong: thermal imaging tends to show the head as warmer than most other parts of the body, and therefore a prime (though probably not to the extent of 40%) site of heat loss, because that's how thermodynamics works. I also have issues with the cite itself: it's a journalistic take on a scientific paper, and as a scientist, I'm very aware of how misleading those can be. Careful reading indicates that the core principle... that for maximum heat retention you should wear a hat when it's cold, because otherwise much of your heat loss will occur through your uncovered head instead of your covered thighs, torso, etc. ... seems valid (note in particular the Army study mentioned in the citation itself). It's clear that the belief that the head in particular somehow loses more heat than similarly sized parts of the body, all else being equal, is wrong, but all else is usually not equal: a person is much more likely not to wear a hat when it's cold than they are not to wear, say, pants when it's cold. 68.105.72.35 (talk) 16:35, 5 January 2011 (UTC)

This may be true of humans, but what about animals such as elephants and desert foxes that use their ears as heat regulators? In order for this to be considered a misconception I think it needs some clearer, more directly scientific sources. 151.201.118.97 (talk) 17:18, 5 January 2011 (UTC)

The original made me uncomfortable because it applied a study on a very specific condition to all conditions generally. The citation I gave focused on sedentary patients in a warm environment (chilled intravenously, as a heart surgery patient would be), and showed that under normal conditions, the head seems to lose heat approximately in proportion to it's surface area. As hypothermia sets in, the head's contribution increases, but is not "The majority." I have seen statements (though I wouldn't cite them) that during moderate exercise (before sweating), the head also loses a disproportionate amount of heat due to increased blood flow (somewhat paradoxically).

Another issue, on top of what you mentioned, is that the head is generally more exposed to wind and the elements, which isn't addressed at all in any of the citations.

I tried to make it less strong, but I still find it problematic (I left the Guardian citation so people without access to journals can see something, but I agree that it is pretty weak too.) I'd support further changes or removal. I think that it is a very common exaggeration, but it doesn't seem to be a myth from what I have seen thus far. Kjsharke (talk) 17:31, 5 January 2011 (UTC)

I'd support removal for two reasons.
First, it's not clear to me that the misconception actually exists. People might say, by way of shorthand, that much of our heat loss is through our heads -- leaving unsaid "if you are otherwise dressed for the weather".
Second, the evidence is not quite as simple as is presented in the Guardian article. Though the Guardian article is a third hand source it accurately reports on the British Medical Journal article "Festive Medical Myths". That BMJ article bases its conclusions on another article in the Journal of Applied Physiology. These data are far more nuanced.
The original study does indeed say that heat is lost from the head in proportion to its surface area (more or less). The same study also says that heat loss increases by more than 45% (298 kJ to 440 kJ) if the head is uninsulated and the rest of the body is insulated - which approximates the misconception. Interestingly, some of this increase in heat loss occurs because the rest of the body loses heat faster when the head is exposed to cold.
Furthermore, the core body temperature declines even more quickly than would be expected when the uninsulated head is exposed to the cold -- regardless of whether the rest of the body is insulated or not.
I think that in this case the apparent misconception is actually more accurate, on a practical basis, than the debunking and that failing to act on the apparent misconception could actually be dangerous in some instances. --Bill WHO (talk) 19:28, 5 January 2011 (UTC)

Danish Pastry actually Danish

Napoleon's Height

I think it's worth noting that, although Napoleon was far from being a dwarf, he was pretty short. Notably so by European standards. As stated in the article his height at time-of-death was 1.686 meters (5'6.5"), which is shorter than the average person in all of the European countries listed on Wikipedia's "Human height" page, and is in fact shorter than the average Japanese man (who are a notably short people). I think it's a bit disingenuous to include "Napoleon wasn't especially short" on a page of common misconceptions, when measured against today's standards, he was in fact a notably short man. Perhaps when measured against the people of his own time, Napoleon was of average or perhaps even above average height, but if that's so the article should mention and cite sources to validate such an argument.

I'm not really sure how to sign this, but I am...

Jon Samuelson

According to Average_height#History_of_human_height, the average height of French troops in the mid-nineteenth century was 1.65 m, making Napoleon slightly above average for the time. However, nobility tended to be taller due to better nutrition, so he may have been considered somewhat short among his peers. —Preceding unsigned comment added by 217.157.144.106 (talk) 11:59, 5 January 2011 (UTC)

Sections titles inconsistence

Both sections 2 and 3 of the article talk about USA-based misconceptions only, however section 2 is called "United States politics" while section 3 is just "Law". Since no other section is named after a country, I request section 2 is renamed "Politics", and if in the future more misconceptions from other countries are added to the article then it can be split into subsections, just like section 1. 84.236.255.164 (talk) 10:29, 5 January 2011 (UTC)

bike and gyroscope

The gyroscopic effect is disregarded. However there are two parts to a gyroscope: First it resists turning of the axis of rotation. This effect helps slow the time-constant of the bike falling over once you have some speed. This is why it is more difficult to bike along at pedestrian speed than to pedal at normal bike-speed. The other effect of a gyroscope is: if you try to turn the axis of rotation one way you'll get a force in another direction. This effect, I think is meant when the references say that it doesn't impact bicycle riding (much). Rewolff (talk) 10:32, 5 January 2011 (UTC)

I don't think that's right: the reason why it's more difficult to balance at low speeds is the transmission of your turns of the handlebar into leans depends on speed. The slower you go the longer it takes, and below a certain speed it's too slow: you can't correct your lean quick enough to stop falling over.--JohnBlackburne^words_deeds 10:45, 5 January 2011 (UTC)

I suppose that without the gyroscope, balancing on a bike would be analogous to ice skating (on one foot) -- which is also harder at slow speeds, I think... —Preceding unsigned comment added by 98.114.27.182 (talk) 23:25, 5 January 2011 (UTC)

Ich bin ein berliner

I'm going to jump in and say that the German public were, in fact, amused by this secondary meaning of "Ich bin ein Berliner". Near everytime I would get doughnuts in Germany, somebody would smirk and asked if I knew the story. The way the misconception is stated, it seems to indicate that there was no secondary meaning, and that Germans didn't find it amusing. I'll buy the idea the German he used was correct in the way he intended, but the external links from the article and everything I can find indicate that the secondary meaning was understood and laughed at. 142.162.19.202 (talk) 17:50, 5 January 2011 (UTC)

I'm a German native speaker born in Frankfurt, now living in Berlin. It is true, that it would be more common to say "Ich bin Berliner", without the article, but it does not sound wrong to me to include it. It's also true, that "Ich bin ein Berliner" would be what one would say to identify oneself as a jelly doughnut. However, as the article correctly states, the word "Berliner" for jelly doughnut is common in most of Germany, excluding Berlin. I don't think the average guy who grew up in Berlin even knows that the word "Berliner" carries a second meaning outside of Berlin. That didn't stop anybody from having a small chucke over the anecdote. In Berlin Doughnuts are called "Pfannkuchen". Everywhere else a "Pfannkuchen" is just what you get when you translate the word literally - Pan Cake. --87.162.104.206 (talk) 20:30, 5 January 2011 (UTC)

The context of the phrase is misstated. See e.g. http://www.americanrhetoric.com/speeches/jfkberliner.html so JFK was referring to himself, if only figuratively. 'All -- All free men, wherever they may live, are citizens of Berlin. And, therefore, as a free man, I take pride in the words "Ich bin ein Berliner."' Also, as a native speaker of german I can confirm the contribution from 87.162.104.206. 93.232.140.203 (talk) 22:51, 5 January 2011 (UTC)

It depends on where you are in Germany. As the article states, "Berliner" isn't used for a Jelly Doughnut in Berlin; however, it is used in other parts of Germany. To Berliners, the meaning was quite clear. In other areas of Germany, the double-meaning was present and it is a good joke. —Preceding unsigned comment added by 70.236.66.210 (talk) 00:41, 6 January 2011 (UTC)

When checking the cited source, it clearly states that, "Berliner" was not commonly used to refer to the doughnuts in the Berlin of the 1960s. As a German, I can verify that it is in fact a widely spread and very common word. I think most of the confusion arises from the fact that Germans nowadays think it's funny, but the Germans from that time didn't. I'd suggest changing "The word Berliner is not commonly used in Berlin to refer to the Berliner Pfannkuchen;" to "The word Berliner was not commonly used in Berlin at that time to refer to the Berliner Pfannkuchen;" (much to my own suprise as well btw ^^) --91.89.3.92 (talk) 02:41, 6 January 2011 (UTC)

Male/Female mosquitos and crane flies

Crane flies are often mistaken for male mosquitos. This is due to the commonly spread knowledge that male mosquitos are larger than females, and that male mosquitos do not bite humans. Male mosquitos are nectar feeders, and can be larger than females, but mosquito size is rarely larger than 16mm (0.6 in), compared to the crane fly whose average size ranges from 2 to 60 mm (0.08 to 2.4 in). — Preceding unsigned comment added by StPuglo (talk • contribs) 11:44, 5 January 2011 (UTC)

Sports->Cow tipping: "killing it"?

In the sports section:

Cow tipping is commonly believed to be a rural practice in which a cow sleeping on its feet is tipped over, killing it.

Physics: Cold does not radiate

Cold is the absence of heat and hence cannot radiate any more than darkness (which is the absence of light). Cold objects (above absolute zero) in fact radiate heat (blackbody radiation), just less so than warm objects. The illusion of cold 'radiation' derives from the cooling of air around cold objects as heat seeps into them. In a vacuum, you would nor feel any such 'radiation' of cold. —Preceding unsigned comment added by 217.157.144.106 (talk) 11:52, 5 January 2011 (UTC)

Please provide a reliable source that this is a common misconception; not just that cold does not radiate, a source that it is a common misconception. 15:34, 5 January 2011 (UTC)

Not an actual source, but a Google search for the phrase "letting the cold in" produces nearly 32,000 hits, which is fair evidence that a substantial number of people do think this way. On the "no, don't include it" side, the majority of hits on the first page are to sites objecting to the phrase on the grounds that it's scientifically incorrect.68.105.72.35 (talk) 18:28, 5 January 2011 (UTC)

I dispute that it is inacurate. Indeed, I would even say that "letting the cold in is a misconception" is itself a misconception. Opening the door of a house on a cold day will physically let cold air flow into the house. This is nothing to do with radiation (and I don't know of anyone claiming it is), but rather Advection and/or Convection Wardog (talk) 00:03, 6 January 2011 (UTC)

You're quite right: number of Google hits is not a reliable source. Google hits vary drastically depending on how you word it. I just Googled "cold radiates" and got a grand total of 1470 hits. And you don't know how many of your 32,000 hits could be about "letting the cold in" not being a valid idea. Google hits mean absolutely nothing, and it does not conform to Wikipedia policy. Cresix (talk) 18:35, 5 January 2011 (UTC)

More importantly, what you say is untrue. In a vacuum without heat radiation (provided you keep your blood from splattering in all directions due to presure loss) you would feel cold, because your body radiates heat but recieves no heat radiation. Satellites, my area of expertise incedentally, have a hot side and a cold side. The cold side constantly looses heat and can cool down to a few kelvin, if it is insulated from the hot side.--87.162.104.206 (talk) 20:39, 5 January 2011 (UTC)

Dinosaurs & Humans

It is a common misconception even among adults that humans and dinosaurs (in the ordinary sense of the term) coexisted.

This (may or) may not be a common misconception in Europe, but I would guess that it's commonness in the US has far more to do with popular media portrayals of humans and dinosaurs coexisting (e.g., The Flintstones), than with creationism. Some of these media portrayals may be popular in Europe as well. The Lost World was written by an Englishman (although perhaps it doesn't really touch on the misconception since it dealt with dinosaurs existing in modern times rather than cavemen and dinosaurs coexisting.

Date of Christ's Birth

The current entry in the list says the following:

"Contrary to popular belief[161], there is no evidence that Jesus was born on December 25[162]. The Bible never claims a date of December 25, but may imply a date closer to September.[163]. The celebration of Christmas on December 25 was likely chosen to coincide with the pagan holidays celebrating the Winter Solstice."

While the first couple of sentences are fine, the last sentence is itself a common misconception. The pagan holiday celebrated on December 25 was instituted by Roman emperor Aurelian (ruled 270-275 AD) as an attempt to unify the various pagan factions, due to his hostility with the Christians. The Christian use of December 25 was based on an old Jewish belief that the Prophets of Israel died on the same day as their conception or birth date. Early calculations (which were probably wrong) put Christ's death on March 25, hence it was believed that he was conceived on that day (now the Feast of the Annunciation, celebrating Gabriel's visit to Mary). Add 9 months to that day and you have December 25. Source: William J. Tighe, Associate Professor of History, Muhlenberg College, Allentown, PA as described in the article Calculating Christmas.

Bellde (talk) 12:19, 5 January 2011 (UTC)

Sorry but that's not correct. The Roman holiday of Brumalia was celebrated before on that day. The Greek Lenaia, Jewish Hanukkah and Roman Saturnalia also took place on or around that day. What you are referring to is the holiday of Sol Invictus, which was instituted by Aurelian later. Your theory is included in the article in the section "Sol Invictus and Christianity" though. Nevertheless, this article does not talk about the holiday of Sol Invictus and as I pointed out before, other holidays were celebrated on that day, long before the birth of Jesus. Regards SoWhy 12:32, 5 January 2011 (UTC)

I was indeed referring to Sol Invictus (see the source article I mentioned). Brumalia was indeed held on 25 Dec, as a celebration to Bacchus, and not the "sun worship" attributed by some to the Christian intent to take over the date. Lenaia was a minor holiday, and thus not likely a prime candidate for the early Christians to try and take over; Saturnalia was originally on 17 Dec and later made a longer celebration from 1-23 Dec, so close to 25 Dec, but not the same. The Sol Invictus wiki page refers to the 1908 Catholic Encyclopedia as advocating for the pagan influence on the choice of 25 Dec, but that is an erroneous reading of the page (go check it out: [14].

The Sol Invictus article goes on to say that the view I expressed above is disputed by others (obviously true), including many Christians, but ignores the fact that the academically well-versed leader of over half of the Christians in the world (Catholics represent 50.99% of all Christians according to the CIA World Fact Book) does express this same view, so technically (although not necessarily actually) the Christian majority actually supports this view.

My suggestion for the misconception page would be to change the last sentence to something like "There are 2 primary schools of thought as to why December 25th was chosen to celebrate the birth of Christ: 1) it coincided with 9 months after an early calculation of Christ's conception being on March 25 (footnote: Calculating Christmas); and, 2) it served as a Christian replacement for the Roman holiday of Sol Invictus. Catholic Christians tend to express the former view whereas Protestant Christians the latter."

Meteorites are cool when they land

"When a meteor lands on Earth (after which it is termed a meteorite), it is not usually hot. In fact, many are found with frost on them. A meteoroid's great speed during entry is enough to melt or vaporize its outermost layer, but any molten material will be quickly blown off (ablated), and the interior of the meteoroid does not have time to heat up because the hot rocks are poor conductors of heat.[47] Also, atmospheric drag can slow small meteoroids to terminal velocity by the time they hit the ground, giving the surface time to cool down.[48]"

I do not doubt the logic of this entry (or that it is a common misconception that meteorites are necessarily hot). But this is currently written as if freshly landed meteorites are always cool or cold. First, the sources listed are not clearly attributed to the correct information in the article. For example, source #47 is talking about the conductivity of rocks in the Earth's Crust ("meteor" or its derivatives are found nowhere in the article). And while this statement may pertain to a stony meteorite, it's probably not true of an iron meteorite. Source #48 is a book, which I don't have, but I trust that someone here might. Second, the only reference I can find to the statement that "many are found with frost on them" is in a forum discussion, author anonymous.

Quoted from the American Meteor Society's FAQ: "9. Are meteorites “glowing” hot when they reach the ground? Probably not. The ablation process, which occurs over the majority of the meteorite’s path, is a very efficient heat removal method, and was effectively copied for use during the early manned space flights for re-entry into the atmosphere. During the final free-fall portion of their flight, meteorites undergo very little frictional heating, and probably reach the ground at only slightly above ambient temperature. For the obvious reason, however, exact data on meteorite impact temperatures is rather scarce and prone to hearsay. Therefore, we are only able to give you an educated guess based upon our current knowledge of these events."

I believe the language in this entry should be softened to match what the AMS FAQ actually says, which is that they are not necessary hot. If no one objects, I can do this ASAP. (Unless some other sources to the contrary are found in the Bad Astronomy book?)

As a note: The discussion on this entry is in Archive #6 from 2009. It pertains to adding sources, which I find ironic in this sort of article (isn't the lack of sources how these misconceptions get started in the first place?) Will.i.am (talk) 13:13, 5 January 2011 (UTC)

Many don't even know that much. Cresix (talk) 22:06, 5 January 2011 (UTC)

Which by the way is another misconception; no precise enough clocks were available to measure anything like that. One of his students made that up. --Echosmoke (talk) 23:25, 5 January 2011 (UTC)

You don't need a clock at all to see that a 10 pound ball and a 20 pound ball hit the ground at just about the same time rather than the 20 pound ball hitting the ground while the 10 pound ball is only halfway down. I'm not saying the story is necessarily true, simply that the lack of precision timepieces cannot be used to disprove it. 68.105.72.35 (talk) 15:34, 6 January 2011 (UTC)

Scientific method

This section is all but meaningless. What exactly is meant by "genuine science" and how is it determined? Get rid of it. Turkeyphan^t 13:23, 5 January 2011 (UTC)

...ie, not pseudoscience. The misconception is that fields that don't use "the scientific method" aren't sciences. See talk archives for more. Hairhorn (talk) 13:51, 5 January 2011 (UTC)

If you don't understand why this is MASSIVELY problematic, I'm not really sure where to start. Perhaps a basic philosophy of science course would help. That aside, please could you refer me to particular talk archives that attempt to show why this section isn't meaningless and in need of removal? Thanks. Turkeyphan^t 01:24, 6 January 2011 (UTC)

I think you're rather missing the point. The misconception is that fields that don't use the "scienctific method" so-called are ipso facto not sciences. But since there is no single scientific method, whether or not a field uses it is not a good way of distinguishing sciences from non-sciences. The archives are easily found using the search function, one relevant discussion is here. Hairhorn (talk) 04:06, 6 January 2011 (UTC)

I'm not missing the point - I'm pointing out the entire concept is fundamentally flawed and cannot be sustained. It needs to go. Turkeyphan^t 18:51, 6 January 2011 (UTC)

You'll have to point which concept is flawed then... if you think the activity of distinguising "science" from "not science" is flawed, then it's moot whether you think there is a single scientific method or not. Hairhorn (talk) 19:50, 6 January 2011 (UTC)

To offer some light on where the objection is coming from, Larry Laudan's analysis offers a survey of attempts to demarcate science and pseudoscience and shows the flaws in each. Turkeyphant is right, this is still very much an unsolved problem. See also: the original article. M.Levin 20:19, 6 January 2011 (UTC)

Part of the misconception is that there is a clear line between science and non-science, and the line is "scientific method". So conceding that this is an unsolved problem only reinforces the view that there is a misconception at play. Since you don't dispute the issue at hand (that there is a single technique used by all scientists) feel free to suggest an alternate wording. Hairhorn (talk) 22:04, 6 January 2011 (UTC)

The whole section ought to be removed. It is merely expressing an unusual philosophical view. It is not a misconception like the rest of the article. Roger (talk) 01:49, 7 January 2011 (UTC)

There's nothing fringe or unusual about this at all. See for example, "RECURRING SCIENCE MISCONCEPTIONS IN K-6 TEXTBOOKS". Hairhorn (talk) 03:21, 7 January 2011 (UTC)

I have to question the Berkeley reference used there -- I fail to see why their definition of 'science' is necessarily more valid than others. They include no citations; the text seems reasonable, but so do many others on the subject. I admit I don't have access to the other listed reference, but I'm really not sure that the 'scientific method' should be kept in a 'list of common misconceptions', when the misconceptions depend on interpretation and aren't entirely agreed upon.

Edit Sports: Bulls are not enraged by the color red...

This entry states that "Cattle are red-green color-blind." This is misleading (and might itself be deemed a common misconception). In fact, cattle are dichromatic (see Jacobs GH, Deegan JF 2nd, Neitz J., Vis Neurosci. 1998 May-Jun;15(3):581-4. "Photopigment basis for dichromatic color vision in cows, goats, and sheep."). While cattle might not be highly sensitive to the color red (which is what should be written to replace the quoted statement from the wikipedia article), it is not pertinent whether they are "red-green color blind" (deuteranopic) because the use of the cape in bullfighting does not rely on the distinction between the colors red and green. Furthermore, because cattle are not trichromatic (as are humans, where wild-type humans have three types of cone cells that detect red, green, and blue light), they don't have the opportunity to suffer "red-green color-blindness" as humans do. Red-green color-blindness can arise from mutation in either the red opsin or green opsin gene, leaving one less-able to distinguish the two colors. Because cattle don't have both a red opsin and green opsin gene, it is not possible for them to become clasically red-green color blind via genetic mutation.

The red color in the capes is used to hide the blood stains on it. —Preceding unsigned comment added by 81.202.28.224 (talk) 10:51, 6 January 2011 (UTC)

Fan Death

Fan death is not really a misconception the way it is stated here. There are 2 misconceptions about fan death: how it happens and that fan death is a myth. Fan death is not a myth according to the US EPA. http://www.epa.gov/hiri/about/pdf/EHEguide_final.pdf page 37 section 4.2.2 explains fan death and how and it happens. JaySee55 (talk) 13:46, 5 January 2011 (UTC)JaySee55

From reading that reference, I get "fans make the air cooler" is a myth, and that improper use of a fan when the air temperature is above body temperature can actually make things worse (due to dehydration). It's a bit of a stretch to go from that to claiming "fan death is not a myth". 68.105.72.35 (talk) 15:45, 6 January 2011 (UTC)

Agreed. The EPA is warning people to not assume a fan alone will prevent death from heat stroke. The Korean doctor believe fans will cool a room until you die of hypothermia. I have personally met people who believed if they left a fan on in their room all day (with doors and windows closed) the room would be cool when they got home. --Skintigh (talk) 18:29, 6 January 2011 (UTC)

It is also common for shops to run a self-contained refrigerator with the door open, in the hope of cooling the whole premises ! (Ignoring the added heat pumping out of the back ...) Of course, it could be a useful dehumidifier ?

I also have my doubts about evaporative coolers that might cause a tiny temperature drop, at the expense of a huge increase of humidity !

Forbidden fruit misconception

Something to add to this section, if you examine the etymology of the word 'apple' in, I think, Old English, you find that the word was just a generic word for a piece of fruit, and did not specify any particular one. It was only later when its meaning changed but the Bible did not that the misconception arose that the forbidden fruit was an apple. Essentially it came about as a translation error in the Bible. Haven't bothered to track down the article I read this in, but etymological references should not be hard to find. 118.210.47.181 (talk) 13:49, 5 January 2011 (UTC)

They aren't. Wiktionary http://en.wiktionary.org/wiki/apple supports you that aepple was used for fruit in general. Unfortunately, a) the Bible was, as far as I know, never translated into Old English and b) the word "apple" does not appear in Genesis at all in the King James Version; the relevant passages use the word "fruit". That doesn't mean the belief couldn't have arisen from some sort of similar confusion (for example, French pomme (apple) derives from Latin pomus (fruit)), it just means that Old English probably isn't directly involved. 68.105.72.35 (talk) 18:11, 6 January 2011 (UTC)

Sarah Palin

The Palin entry keeps being reintroduced without discussion, after a clear consensus to delete. Hairhorn (talk) 14:50, 5 January 2011 (UTC)

Chemistry: Water

I think that the single word "usually" needs to be taken out from the first bullet.

Completely pure water is not a good conductor of electricity.[146] In practical situations (such as bathtubs, flooded basements) water usually contains impurities (electrolytes) which allow for good electrical conduction.

In 'practical' situations (which I don't know what that means as many practical applications require pure water) or maybe better household applications, water ALWAYS has impurities. A perfectly pure water source would be lethal to humans due to Le Chatelier's principle as water becomes an aggressive solvent when pure.

This might clear up an misconception that in 'practical' applications there is sometimes 'pure water.' (It isn't even close in actuality.)

Merci. —Preceding unsigned comment added by 76.75.103.161 (talk) 14:51, 5 January 2011 (UTC)

Now that's just another misconception. That pure water is lethal, that is. It might be in the (very) long run as it, consumed exclusively in large quantities and without proper amount of electrolytes in food, causes elimination of electrolytes from the body, which in turn influences serum potassium concentration, which in turn fucks up your heart among other things. We should add that i think. --Echosmoke (talk) 17:08, 5 January 2011 (UTC)

Palin: I can see Russia from my house

Despite the decision in mid-2010 to remove this misconception, the following links (and there are tons more that can be found with a simple Google search) show that it is, in fact, a common misconception:

• Palin: I can see Russia from my house!

• Sarah Palin "I Can See Russia From My House" Refrigerator Magnet

• I Can See Russia From My House

It's referenced in the List of Misquotations already, which is arguably a much better place for it anyway.68.105.72.35 (talk) 18:21, 5 January 2011 (UTC)

It belongs in the politics section every bit as much as the Al Gore item. In both cases, a politician said something. In both cases, what they said was true. In both cases, a humorous misquote which makes the politician look like an ass is thought by very many people to actually be something the politician said.

There is no need for a re-consensus to overturn a prior consensus, particularly a narrow one which took place over 6 months ago. This is a sourced item and belongs where it is. - Lisa (talk - contribs) 18:36, 5 January 2011 (UTC)

Actually, there would be a need for a new consensus. Unless an item is reliably sourced as a common misconception, it can only be included by consensus. The fact that the previous consensus is over six months old is all the more reason for a new consensus: things like this can change dramatically in six months. For example, Palin went from being an unknown to being a major national figure within a matter of weeks. We're not talking about hard facts; this is an "idea". Ideas change rapidly. Cresix (talk) 18:42, 5 January 2011 (UTC)

There isn't a need for a new consensus. The citation stands on its own. To say otherwise suggests that certain editors "own" this article by virtue of having been here first. That's not how Wikipedia works. If there was a prior consensus (and I don't think there was), it isn't the consensus that matters, but the reasons given that there was a consensus about. The reasons are what pertain here; not the consensus. - Lisa (talk - contribs) 19:56, 5 January 2011 (UTC)

In addition, when I look at the "consensus" Hairhorn linked to, I don't see anything of the sort. Hairhorn wrote there "I don't see how this is a misconception, I don't see a good source for it as a misconception." I've posted sources for it as a misconception. Is ABC News not a reliable source for such things? You can Google it and see how common a misconception it is.

Please give specific numbers. Otherwise, it's not a reliable source. Don't be silly. Cresix (talk) 20:10, 5 January 2011 (UTC)

Not to intrude on the arguments of quality of sourcing, but I think most people know Fey said it instead of Palin. Most people attribute it to Palin on purpose to make her sound dumb, but intentional slander/misquotation is not the same thing as misconception. It belongs in the article about misquotations, but not here. (Just my two cents.) Spidey104 20:35, 5 January 2011 (UTC)

At the risk of revealing my lack of connection to popular culture, I thought Palin had actually said it; I stopped watching SNL about the time the original cast left, so I'm only vaguely aware of who Tina Fey is. I agree that it belongs in misquotations rather than here, but I suspect more people than you think do in fact believe Palin said it due to how widely it was quoted, without attribution, in the media. 68.105.72.35 (talk) 18:22, 6 January 2011 (UTC)

{{edit semi-protected}} Under the Evolution category, all statements are made with the presupposition that Evolution has been proven. There is a great misconception that evidence equates proof, when in fact are not equatable. Similarly, proponents of Creationism have many evidences that their position is true, however nobody ANYWHERE has absolute proof. If the section is only meant to clear misconceptions about evolution, it should be rewritten in a way that doesn't mislead readers to believe that Evolution is a scientifically proven fact. Maybe adding a section above the Evolution section (entitled Origin of Life or something to that nature) that explains that a common misconception is that there is a scientifically proven law of the origin of life and that Evolution itself is a misconception would be the appropriate action to take, in order to provide neutrality in this discussion.

Under the evolution heading, the following clause exists:

"The word theory in the theory of evolution does not imply doubt from mainstream science regarding its validity...."

A theorem might be valid, but a theory can only be strong or cogent. While this might be nitpicking, the logical import of the distinction is rather large. Thus, please replace the above clause with the following:

I thought this wording was actually weak. A hypothesis is an idea that fits known facts and observation, is testable, and is falsifiable. A scientific theory is a hypothesis that has been rigorously tested, has been agreed upon by the majority of the scientific community, is the best explanation available, and often ties many different fields of science together into one explanation. For instance, evolution ties together what we know about inheritance, paleontology, DNA, microbiology, and even complex systems like populations and computer science. Gravity ties together classical mechanics, astronomy, relativity, etc. Germ theory of disease ties together observations in medicine, biology, sanitation, etc. --Skintigh (talk) 18:43, 6 January 2011 (UTC)

In addition, there are supposedly parallel highway access roads on most of the original overpasses so that in the even the overpasses were bombed, military transports could still continue along to the other side by using the access roads.

The current wording is still perhaps a bit stronger than is warranted. See the discussion at http://en.wikipedia.org/wiki/United_States_Declaration_of_Independence#Signing, which includes citations both supporting and arguing against the August 2 date. I think the most it's fair to say is that we are not certain exactly when the declaration was signed, though the physical document most people think of as the Declaration of Independence (i.e. the one in the National Archives) may well have been signed at least primarily on August 2, with some signatures potentially being added later. (A bit further down, reference is made to the Dunlap Broadsides, printed the night of July 4, which while not having an actual signature included the phrase "Signed by order and on behalf of the congress" followed by John Hancock's printed name, with Thomson listed as witness.) It might be worth mentioning the distinction between the Declaration of Independence as an ideal, and the physical document on display in Washington. Actually, that alone would be sufficient to quell my reservations. Ptorquemada (talk) 19:58, 6 January 2011 (UTC)

I maintain that 1.68m is in fact short, as in "below average", for a french man of that time and certainly for a french man of today. Even more so for a commanding officer who was thus bound to be much shorter than many of his officers and soldiers, which cetainly added to the perception (I expect he was on horse often though). But I realize that his shortness is often exaggerated even more. And yes, I arrived here via xkcd as will many others, I'm sure.

"There is no evidence that Vikings wore horns on their helmets.[18][19]" seems to me too unexplanatory. I suggest two additions: firstly, that common Viking soldiers wore plain metal or leather helmets if any (this is backed up by the references already in place). Secondly, to my knowledge one part of the misconception of horns originates from the towns and villages that were raided by the "devillish" Vikings; especially religious accounts of these horrible and fierce attackers attribute them with horns as a sign that relates to devil. This may have lead to some imaginative artists depicting Vikings with both devil horns and also a tail in some occasions.

Unfortunately I'm not able to provide a good reference for the latter information, so I do not insist its addition unless somebody else can help with that. 88.195.167.85 (talk) 16:05, 5 January 2011 (UTC)

Who Invented What?

Spinoffs of the Space Program (Velcro, ...):

From http://www.nasa.gov/offices/ipp/home/myth_tang.html

Are Tang, Teflon, and Velcro NASA spinoffs? Tang, Teflon, and Velcro, are not spinoffs of the Space Program. General Foods developed Tang in 1957, and it has been on supermarket shelves since 1959. In 1962, when astronaut John Glenn performed eating experiments in orbit, Tang was selected for the menu, launching the powdered drink's heightened public awareness. NASA also raised the celebrity status of Teflon, a material invented for DuPont in 1938, when the Agency applied it to heat shields, space suits, and cargo hold liners. Velcro was used during the Apollo missions to anchor equipment for astronauts' convenience in zero gravity situations. Although it is a Swiss invention from the 1940s, it has since been associated with the Space Program. — Preceding unsigned comment added by Markgalassi (talk • contribs) 21:33, 5 January 2011 (UTC)

Evolution does not claim humans evolved from monkeys

Evolution does not claim humans evolved from monkeys, chimpanzees or any other modern-day primates. Instead, fossil evidence has shown that humans and monkeys share a common ancestor that lived about 40 million years ago. This common ancestor diverged into separate lineages, one evolving into so-called New World monkeys and the other into Old World monkeys, apes, and humans. Similarly, the common ancestor of humans and chimpanzees, which lived between 5 and 8 million years ago, evolved into two lineages, one eventually becoming modern humans and the other splitting again into chimpanzees and bonobos. Thus, one cannot consider any present-day monkeys or apes as reflecting how humans "used to look" or behave. All extant animal groups have evolved over the same amount of time.

I think this is just wrong. Humans did evolve from monkeys. Humans are apes and apes diverged from the Old World monkeys. See here. However Humans didn't evolve from any modern-day primate, but this text is at least misleading. --92.199.199.217 (talk) 16:36, 5 January 2011 (UTC)

Old World in the phrase "old world monkeys" refers to the Eastern Hemisphere and has nothing to do with age. To the extent that I understand the original complaint, I think the objection seems to be that if we go far enough back on the evolutionary path leading to humans and somehow transferred a member of such a species to the present day, most non-specialists would call it a "monkey" and it would not raise many eyebrows if seen in a zoo next to, say, the gibbons. —Preceding unsigned comment added by 68.105.72.35 (talk) 17:54, 5 January 2011 (UTC)

I agree that the PBS source is at best an oversimplification, if not outright wrong. The problem is the same as in the birds/dinosaurs dispute: there are two senses of the word, a precise cladistic one and a problematic common one. "Monkey" is commonly understood as excluding apes, and "ape" is commonly understood as excluding humans. These categories are ok for common usage about extant organisms, but there's no good way of extending them to apply consistently to the common ancestors. The cladistic terminology does make sense. So the common ancestor of monkeys (and apes) is best understood to be a monkey; the common ancestor of apes (and humans) is best understood as being an ape. Humans thus are monkeys that evolved from other monkeys, and apes that evolved from other apes. The common misunderstanding is that people imagine different modern forms as having evolved from each other, rather than from an ancestor that strictly should not be identified with either. The common ancestor may resemble one of the modern species much more closely than another, which can roughly be expressed as saying that the latter species evolved from the former. For example we quite reasonably say, "The Hawaiian Goose evolved from the Canada Goose (Branta canadensis)" even though strictly we ought to distinguish between the current Canada goose and the species as it existed before separation from the latter. The article needs clarification. --Dan Wylie-Sears 2 (talk) 13:22, 6 January 2011 (UTC)

Man did not evolve from monkeys and apes because monkey and apes did not exist at the time man first evolved, so it is impossible to have evolved from them. We share a common ancestor. Think of them as very distance cousins. Would you claim you are descended from your distant cousin? Of course not. You may share a great-great-grandparent, but you most likely were not born directly from your cousin. Using incorrect terminology only confuses people and invites fallacious quips like "if man came from monkeys why are there still monkeys?" --Skintigh (talk) 18:59, 6 January 2011 (UTC)

Well, the reference contains this "Children's misconceptions about weather ... Air and oxygen are the same thing (Stepans, 1994)."

Inertia, not Centrifugal Force

There is no such thing as "Centrifugal Force," meaning a force which moves an object away from the center during rotation - for example, when you tie an apple to a string and twirl it around, the apple is being forced away from your finger by centrifugal force. Rather, inertia means that the apple will continue moving in a straight line unless it is held back by a centripetal force (the tension in the string). So if the string breaks, the apple will move away from the person's finger, but this is as a result of inertia, not centrifugal force. wikipedia article: http://en.wikipedia.org/wiki/Centrifugal_force

I'm not an expert at wikipedia entries, but this would probably qualify as a misconception. — Preceding unsigned comment added by KC McGinnis (talk • contribs) 17:26, 5 January 2011 (UTC)

It has to be more than a misconception. Please provide a reliable source that it is a COMMON misconception. Cresix (talk) 17:30, 5 January 2011 (UTC)

Actually, in my experience, the more common misconception is that there is no such thing as centrifugal force. To cite the wikipedia article you just cited, http://en.wikipedia.org/wiki/Centrifugal_force Centrifugal force is a force found only in rotating reference frames, much like the Euler and Coriolis (sp?) forces. As a matter of fact, the existence of a centripetal force, implies the existence of a centrifugal force under Newton's Third Law. (see http://en.wikipedia.org/wiki/Reactive_centrifugal_force)

Now you could possibly say Centrifugal Force is a subclass of inertial forces applied to rotational motions, or that it is a result of inertial forces, but to say that it does not exist is sort of like saying that Drag does not exist (as a force) After all, if you look closely at drag, you will see that it is really just friction. Jared Thaler (talk) 00:16, 6 January 2011 (UTC)

It's probably due to conflation with regular water poisoning (see Leah Betts, et al.) Turkeyphan^t 18:45, 6 January 2011 (UTC)

Snopes vs. LoCM

What is the actual point of this article? Is it to eventually grow and become some kind of debunk page of misconceptions and (urban) legends, along the lines of Snopes?

Look at the archives. Similar discussions in the past. The article is limited somewhat because items must be reliably sourced as COMMON misconceptions (or accepted by consensus as such). For every item in the article, there are HUNDREDS that have been removed as not common. So it's not exactly a random list of misconceptions. Cresix (talk) 17:39, 5 January 2011 (UTC)

Ok, to be fair, very few of the entries on this page seems to meet the criteria of being reliably sourced as being a common misconception. At least on some of them you specify in which culture or population the belief is common. For instance, the Air=oxygen entry only has a reference where a study was done on children. The Let them eat cake entry is another, where I can emotionally agree that i believed this to be true, and therefore think that it is a common misconception, but here no reference is made to support the fact that it is a common misconception. Most entries in the article follow the latter format, and when people suggest additions to the article they are met by Please submit a source that it is a common misconception. What about these other entries? Are they grandfathered in? Is there some kind of voting system in place? --Popoi (talk) 17:52, 5 January 2011 (UTC)

You're "preaching to the choir", Poposhka. No need to demand from most of us that we "submit a source"; many of the contributors to this talk page prior to today (most of today's contributors are a flash in the pan because the article got some press) have thrashed out these issues quite extensively.

For the remainder that might be poorly sourced, feel free to challenge them. Cresix (talk) 17:58, 5 January 2011 (UTC)

It different from most articles because of the dual sourcing aspect: sourcing that the facts are accurate, and sourcing that the misconception is common. It's that second roadblock that kills the vast majority of items. Cresix (talk) 18:05, 5 January 2011 (UTC)

I think what Popoi is referring to is the fact that unsourced material stays in this article since no one is challenging it (what you call consensus, basically). This however is true for all of WP, just usually ppl may be more keen on challenging. --Echosmoke (talk) 23:59, 5 January 2011 (UTC)

Art Techniques

"Mixing Red and Blue makes Purple". This is something that nearly everyone "knows" and is in fact wrong, unless you are talking about a very specific blue (red shifted) and a very specific red (blue-shifted). Generations of teachers have simplified the "primary colors" as Red, Yellow and Blue, and they don't tend to teach anything about "shifts".

What most people are taught as the "primary" colors of pigment they learned as a kid: fire-engine red and a sort of medium blue (close to the color of a post box, a little less green and dark if they are lucky), and yellow. What you get when you mix that red and that blue can be nearly black- a gray muck with a suggestion of purple.

What are the real Primary Colors in pigment? You will find them in color printer cartridges: Magenta, Cyan and Yellow. If you look at the adult or professional caliber acrylic paints in a good art store you should find Primary Magenta, Primary Cyan and Primary Yellow. Sometimes children's paint companies will label magenta (which looks a little pink) or a magenta/red mix as "red" and it perpetuates the myth that red works, because that "red" does.

Mixing With True Primaries:

To get purple, mix Cyan and Magenta. A little bit of magenta and a lot of cyan will get what most people are taught is "primary blue". Cyan and yellow will get a full range of greens in a purer saturation than if you use blue and yellow (since blue contains some magenta, and will therefore neutralize the green a little). Yellow and Magenta will give you orange. A small amount of yellow added to magenta will give you what most people are told is "primary" red.

When one gets into professional oils and acrylics which use minerals things get infinitely more complex as transparency, reflection, opalescence, and opacity are introduced. I recommend Gamblin Oil's website for learning about that.

There are also some visual effects that change how we see pigment. The most known is that if you mix black and yellow you get something that looks green. It's an optical effect not a pigment reaction, one of many.

This isn't a misconception. The belief may be widespread, but that's at least partially because it's approximately true. Mixing just about any shade of red and any shade of blue will produce some shade of purple. It may not (in fact, probably won't) be a bright, clear purple, but it isn't actually wrong as such. 68.105.72.35 (talk) 16:20, 6 January 2011 (UTC)

I came to say something similar. Schools teach the primary colors of pigment (or subtractive primaries) are red, yellow, and blue. This is FALSE, as you stated. They are magenta, yellow and cyan, which are the secondaries of the (additive) primary colors of light: red green and blue, which are determined by the red, green and blue color sensors in the average human eye, and that is why the screen you are staring at is made up of red, green and blue dots. There is no way to mix non-primary colors to form a primary color, so you could never mix red, yellow and blue pigment to form magenta or cyan pigment. Supposedly, the reason this falsehood is taught is because hundreds of years ago there was no way to make cyan or magenta paint, so approximations were used. As a reference I would use wikipedia, but someone deleted some of those details... http://en.wikipedia.org/wiki/Primary_color#Subtractive_primaries --Skintigh (talk) 19:12, 6 January 2011 (UTC)

The forces exist, and are even helpful, but they are not essential, not necessary. --195.137.93.171 (talk) 06:00, 7 January 2011 (UTC)

Edit request from PhiloHippus, 5 January 2011

{{edit semi-protected}}

In astronomy section, add the misconception that moon phases are caused by the earth's shadow:

• Lunar phases are not caused by the shadow of the Earth or umbra falling on the Moon's surface (this occurs only during a lunar eclipse), they are the result of looking at the illuminated half of the Moon from different viewing geometries.

PhiloHippus (talk) 19:06, 5 January 2011 (UTC)

 Not done You need to show us some sources that this is a common misconception. For me personally, this is the first I've heard of this; I thought it was common knowledge that lunar phases result from the direction of sunlight falling on the moon. ~Amatulić (talk) 00:09, 6 January 2011 (UTC)

Edit request from Pedrorui, 5 January 2011

I updated the list of words, replied to a comment and removed the last item.

Linguistics

. The Eskimo languages do not have an unusual large number of words for snow. In particular, it is not true that these languages use special words in order to distinguish between an abnormally large number of types of snow. Simply, there are many words formed around the concept of snow, which is in itself unremarkable. For example, consider the list of English words that contain the element 'snow': snow (verb), snowing (verb), snowboard (verb), snowy (adjective), snowiest (adjective), snowily (adverb), snow (noun), snowiness (noun), snowplow (noun), snowstorm (noun), snowflake (noun), snowfall (noun), snowdrift (noun), snowboard (noun), snowman (noun), snowslide (noun), snowshoes (noun), snowbank (noun), snowcave (noun), powder snow (noun), snowmageddon (noun), etc.. Eskimo, like English, can form complex words from simple ones. In fact, there is no upper bound to the number of words containing 'snow' in Eskimo, only patience sets a limit, just like there is no upper limit to the English words about the concept of 'mother' as illustrated by "great-grandmother" , "great-great-grandmother", "great-great-great-grandmother", etc..

. Linguists do not have to learn languages. Most linguists speak very few languages, other than their own. The goal of linguistics is to understand how human communication works, but this does not require linguists to be polyglots. Conversely, speaking multiple languages does not make one a linguist. Similarly, a zoologist does not have to become a chimp in order to study chimps. The following aphorism has been attributed to Lynne Murphy: "asking a linguist how many languages (s)he speaks is like asking a doctor how many diseases (s)he has." Ironically, many dictionaries still equate the terms 'linguist' and 'polyglot'.

 Not done: Please provide reliable source that this is a COMMON misconception. Cresix (talk) 19:25, 5 January 2011 (UTC)

The second URL provided above (Globe newspaper) shows this is common. Moreover, the fact that modern dictionaries like Merriam-Webster make such a mistake shows how established this is: http://www.merriam-webster.com/dictionary/linguist

No, the Globe source says nothing about anything being a COMMON misconception. And a dictionary mistake is not evidence for a common misconception; it's evidence for a misconception by a few writers or proofreaders. Cresix (talk) 20:33, 5 January 2011 (UTC)

But here are more sources for this misconception:

NONE of these sources identify anything as a common misconception. Cresix (talk) 20:33, 5 January 2011 (UTC)

There are at least two facebook groups about it; http://www.facebook.com/group.php?gid=2201093513 http://www.facebook.com/group.php?gid=2263085928

Facebook pages mean nothing. I could set up a Facebook page devoted to the misconception that the moon is made of cheese. That doesn't mean it's a common misconception. Cresix (talk) 20:33, 5 January 2011 (UTC)

... Personally, I get asked by immigration services how many languages I know *every* single time I enter the USA via an airport.

What happens to you personally is not a reliable source. I just asked by friend who is a linguist, and she has never been asked how many languages she knows. Cresix (talk) 20:33, 5 January 2011 (UTC)

Pedrorui (talk) 19:16, 5 January 2011 (UTC)

I'm a linguist too (as in, a scientist who studies the workings of language), and I also get asked by people how many languages I speak, but this is not a misconception (altho it certainly is common). If you are employed by the Armed Forces, for example, and are a "linguist," then you are a polyglot. The word "linguist" just has two definitions. An equivalent phenomenon would be if engineers (who build bridges etc.) got annoyed when people asked them what sort of trains they drove. Certainly we can educate the public that there is another kind of linguist out there, but to tell people their usage is wrong makes us no better than the prescriptivists against whom we rail during the first week of 101. --Signor Giuseppe (talk) 20:32, 5 January 2011 (UTC)

Once again, personal experience is not a reliable source. And this article isn't supposed to educate the public about linguists, unless it happens to pertain to a COMMON misconception. Try a blog or Facebook. Cresix (talk) 20:36, 5 January 2011 (UTC)

Cressix, I think you should reread my entry. I have no evidence other than my personal experience, but I wasn't trying to push for this being included, I was reasoning why it should not. Further, as a fellow theoretical linguist, I was trying to put this in our own terms for Cresix. So while there may be a verified poll out there that says 89% of people think "linguist" describes a polyglot, that still means there is no misconception. In our own beliefs about language, in fact, that means "linguist" as scientist is a piece of jargon at odds with the standard definition.--Signor Giuseppe (talk) 20:55, 5 January 2011 (UTC)

You're right. I misread. My apologies. Cresix (talk) 21:18, 5 January 2011 (UTC)

Astronomy Section on Black Holes

I think this item needs to be clarified or deleted. "Because black hole formation is explosive, the object would lose a certain amount of its energy in the process, which, according to the mass–energy equivalence, means that a black hole would be of lower mass than the parent object, and actually have a weaker gravitational pull." A differentiation between the gravity within the black hole's event horizon and the gravity outside of the horizon should be made. If the above sentence were true for both places it wouldn't make sense why light can't escape the "lower" gravitational pull of the black hole when it could escape the "higher" gravitational pull of the star. — Preceding unsigned comment added by Jimmieman (talk • contribs) 19:49, 5 January 2011 (UTC)

The end of the speech of Kennedy goes:

but kennedy wanted to tell "us", that he is _a part_ of the group of the berlin people ("All free men, wherever they may live, are citizens of Berlin(...)", so the use of "ein" is correct, because so he can make a reference to what hey said before. otherwise he would just have told us, he is a citizen of berlin. but the meaning of his sentence is clearle, that he is "one of" (einer dieser = ein) those berlin people. —Preceding unsigned comment added by 80.187.107.82 (talk) 15:44, 6 January 2011 (UTC)

Edit request - Judaism section

Got here via Metafilter, so I'm guessing there may be a lot of activity on this page and didn't want to jump in if all edits are being deleted, but will gladly contribute this section with further details.
There are plenty of common misconceptions about Judaism, so I was surprised to see nothing included. Particularly these three -

• Religious Jews do not have sex through a hole in a sheet
• Kosher food is not blessed by a rabbi in any way
• There is no prohibition against being buried in a Jewish cemetery if you have a tattoo

Not to mention the American misconception that Jews make up a sizeable percentage of the US or world's population - the actual number is somewhere under 2% in the US and well less then 1% worldwide
thoughts? — Preceding unsigned comment added by Mchelly (talk • contribs) 20:58, 5 January 2011 (UTC)

To be honest, I've never heard of any of these misconceptions. The "hole in a sheet" and "tatoo" ones are so ricidulous that I even wonder if your edit is serious. Not only are these not common misconceptions, I doubt that they're misconceptions held by more than a few people. If you disagree, please provide reliable sources that they are common misconceptions. Cresix (talk) 21:22, 5 January 2011 (UTC)

His edit is, indeed, serious. I've heard all these before. Whether or not a sizeable number of people actually believe them is open for discussion and will require reliable sources to show, but I can assure you that some people do, even as absurd as they are. In fact, the hole in the sheet thing was in some major movie or tv show... Seinfeld perhaps? Jess_talk|_edits 21:31, 5 January 2011 (UTC)

• Sex through a sheet: Snopes, JewFAQ, Jewish Mythbusters ~~1.5mil google hits
• Kosher Food: My Jewish Learning, Jewish Cooking, ~~100k google hits
• Jewish Cemetaries: My Jewish Learning, Jewish about.com, Torah.org, NY Times, ~~44k google hits Jess_talk|_edits 21:44, 5 January 2011 (UTC)

None of these sources provides evidence that any of them are common misconceptions. Just my opinion, but I'm starting to think these ideas were picked up by a few Jewish people who found them so ridiculous that they shared them with their Jewish friends just for a laugh. Just like when I was a kid in Catholic school we joked about how all nuns had bald heads, knowing full well that it wasn't true. Cresix (talk) 21:49, 5 January 2011 (UTC)

My intent wasn't to provide reliable sources (otherwise I would have added them to the article myself) but to show their prevalence generally. That said, I'm not sure you read through the links carefully enough. The NY times article definitely provides ample evidence that the tattoo myth is common: "Nearly every Jew, from those who go to synagogue only on holidays to those who dutifully follow Jewish law, has heard that adage." Similarly, I would expect of the nearly 1.5 million google hits for "jewish sex through a sheet", enough to spur a snopes article and countless entries on jewish FAQs, we can find plenty of reason to conclude the misconception is prevalent enough to be considered "common". Jess_talk|_edits 23:02, 5 January 2011 (UTC)

Yes, in fact, I did read the sources. But "hearing an adage" is not the same as a common misconception. Lots of people heard the adage that if a frog pees on you it will cause warts, but that doesn't mean that most people believe it. As for Snopes, that website does not limit itself to common misconceptions. If it did, there would be no need for this Wikipedia article. And as I've said MANY, MANY times on this talk page, Google hits are not evidence that a misconception is common; the number of hits you get depends on how you word the search; if I search "Jewish" + "sex through a hole in a sheet" I get a grand total of 6790 hits. And of the 1.5 million Google hits you got, how many of those actually confirm that it's a misconception, how many disconfirm that it's a misconception, how many refer to a joke about Jewish sex without either confirming or disconfirming, and how many fall into some other category. If you can't give a specific answer to that, Google hits is meaningless. Cresix (talk) 23:17, 5 January 2011 (UTC)

I'll concede that it is anecdotal, however, on more than one occasion, I have asked for Kosher meat, only to be told that the store's meat was "Just like Kosher Meat, except it wasn't blessed by a rabbi." Anecdotal is not evidence, but since it's been stated elsewhere that in the absence of evidence one way or the other, the editors establish the "Common" part of "Common Misconception" through concensus, I just thought I would throw my 2 cents in. — Preceding unsigned comment added by Jared Thaler (talk • contribs) 00:50, 6 January 2011 (UTC)

Thanks for your two cents. Let's see if enough opinions for a consensus are expressed. Cresix (talk) 02:33, 6 January 2011 (UTC)

I wasn't saying that the google count was sufficient in itself - I've been an active editor here for quite a while actually, enough to know it isn't. My point was that it does turn up a plethora of results, many of which are related to the misconception, and among those, surely a suitable RS could be found; I intended to address your initial concern that the OP "wasn't serious", or that the idea wasn't prevalent. Regarding the tattoo, I'm a little baffled that you don't find a NY Times article suitable which explicitly states that "nearly every Jew has heard it", or the various 'Frequently asked questions' pages I provided written by various Rabbis. I'll give you two more which use the exact terminology, http://www.ehow .com/about_4622123_does-judaism-say-tattoos-piercings.html (<-- eHow is blacklisted apparently. Bringing the issue up on RSN) and Ask the Rabbi. I still think the NY Times article is sufficient (even, stronger), and should be used as a source. I'm going to include whichever of these I can quickly find sourcing for in the article. If you still disagree, feel free to revert me and discuss it further. Jess_talk|_edits 02:09, 6 January 2011 (UTC)

Sorry you're baffled, but again "nearly every Jew has heard it" doesn't mean it's a common misconception. I'm Catholic; nearly every Catholic has heard the idea that nuns (in the old days when they wore habits) have shaved heads; I've never met a Catholic who actually believes it; ergo, not a common misconception. As for the chabad.org, it's one person asking a question and one person providing an answer. That clearly does not make it a common misconception. If I ask on a blog whether the moon is made of cheese, does that make it a common misconception? Cresix (talk) 02:33, 6 January 2011 (UTC)

And NO, do not add it without consensus. That's not the way it works on Wikipedia. When there is disagreement and there is ongoing discussion, the proper thing to do is wait for consensus, not add it just so it will be removed. Read WP:CON. Cresix (talk) 02:36, 6 January 2011 (UTC)

Cresix, I understand you've been working on this page for a good chunk of today, and I commend you for that. It's understandable that you might be getting a bit frustrated as a result, and if so, I'd advise you to take a short break to cool down. If I'm off-base, then my apologies, but let's try to keep the discussion a bit level headed if we can. I'm sure you're aware of the BRD cycle, so I'm confused why you would say "that's not how wikipedia works". Further, based on the discussion here, it would appear that consensus is against you for the exclusion of this info, as it seems we have 3 editors supporting the inclusion, which to my mind is reliably sourced with multiple citations. Could you please be more specific about why it is that you disagree with the inclusion, particularly so strongly, and what kinds of sources you'd like to see in order for it to be included? Jess_talk|_edits 03:06, 6 January 2011 (UTC)

Actually, this item was under discussion when you added it, the "D" component of BRD. It's not appropriate to boldly add in the midst of a consensus discussion. But no harm done. As for what kind of sourcing I would like, a reliable source that unequivocally states that the misconception is common (which is more than "every Jew has heard it"; see my comments above) would be excellent. There are some items in the article that actually provide sources specifically stating that it is a "common misconception" or "a misconception held by most people" or even a specific percentage of the population that subscribes to the misconception. Additionally, even if "every Jew has heard it" and every Jew believes it, is that a common misconception in general, or a common misconception among Jews? This is just my opinion, but as a non-Jew, I'd be willing to bet money that most non-Jews have never even heard of this misconception. Finally, you can also add the items if there is a consensus on the talk page to do so. As for your statement that consensus is against me, there is no consensus either way at this time. Review this section. Mchelly presented the possibility that these Jewish-related ideas are common misconceptions, but not providing an evidence that they are. You provided some sources that you think support the idea of common misconception. I disagreed with your conclusions. That does not make a consensus. Consensus can take a while; sometimes there is never a clear consensus. The burden of proof is on the editor who wishes to add the item. Cresix (talk) 03:15, 6 January 2011 (UTC)

I'm going to back away and come back to the page later on, but I'd like to address a few things first. Adding content to an article for the first time is never discouraged, particularly when new sources have been introduced and with explicit acknowledgement that it may be reverted if there is disagreement. I'd suggest you're taking a rather harsh attitude about this issue, which is liable to discourage new editors (which we're getting plenty of today). Secondly, if it's a "common misconception among Jews", that still makes it worthy of inclusion in the article, which is a general compilation of misconceptions -- even among Jews. Thirdly, lots of the content currently in the article isn't sourced to your stated satisfaction here. The NYT article demonstrates that it's a common adage which has widespread acceptance. Orthodox union provides exact wording that it's a misconception which is widespread. That it's been in at least two popular tv shows (Curb your Enthusiasm and The Nanny) lends further support. The fact that I've provided multiple other sources, including chabad - which explicitly calls it a "common misconception" - should even be unnecessary to warrant its inclusion. I'm sorry to say, your opinion that these are insufficient seems unreasonable. Jess_talk|_edits 03:42, 6 January 2011 (UTC)

• "Adding content to an article for the first time is never discouraged": Read WP:BRD again; it's not an invitation to ignore consensus and edit war. Boldly adding content before discussion is never discouraged. Adding disputed content in the midst of discussion is not appropriate. You're wrong about that one.
• "if it's a "common misconception among Jews", that still makes it worthy of inclusion in the article": So every misconception held by any specific group of people is acceptable? Common misconceptions among Quakers. Common misconceptions among Druids. Common misconceptions among Choctaw Native Americans? No, if that was the case the article could multiply in size by a factor of thousands. This article pertains to common misconceptions in general. Moreover, you haven't provided an adequate source that it's a common misconception among Jews. You've simply provided a source that "every Jew has heard it" (regardless of whether they believe it) and a source quoting one person asking a question and one rabbi answering the question, as if that's evidence of a common misconception.
• "lots of the content currently in the article isn't sourced to your stated satisfaction here": Read Other stuff exists. I've never claimed that the article is in perfect condition. I'm trying to keep the new additions properly sourced or included by consensus. That was a fairly manageable task until about 24 hours ago.
• "I'm sorry to say, your opinion that these are insufficient seems unreasonable.": That's your opinion, and you're entitled to your opinion. I'm sorry to say I disagree. And when there is such disagreement on Wikipedia, it is resolved by consensus. Currently there is no consensus, although it seems that the consensus process is not a consideration in your decision to edit the article. I find it interesting that until about two days ago, even though there were some heated debates about the content of this article, a disputed item rarely was added, re-added, and re-added again without consensus. The article gets some press, followed by people like yourself who have never edited the article. And that's fine; I welcome new editors. What I don't welcome is an editor who assumes that because he has never edited the article, he is entitled to run roughshod over the consensus process. But so be it; I'm taking a break from the article; but unlike most people who have commented here in the last 24 hours, I'll be back later to do the heavy-lifting of getting the article back in shape again. Cresix (talk) 15:33, 6 January 2011 (UTC)

Cresix, you're putting things into rather heated territory again. Once again, let's keep the discussion calm if we can. I'll address your points in order.

1) Please read WP:BRD again. Content is commonly added with new sources or new wording during an ongoing discussion as a proposal or to generate consensus. This is common practice, and besides which, that isn't what happened. You objected to the bit about sex through a sheet because it wasn't sourced to your satisfaction, so I improved the sourcing. You are now apparently objecting to the sources being improved... I'm not sure what to tell you - if you think the sources are still insufficient (which I'm just guessing, because you haven't said), you should address that point specifically, not yell at me for improving them. If you think this is a problem, you're welcome to take the issue to WP:RfC or WP:ANI.

2) Being a common misconception among a substantial demographic does make it worthy of inclusion in the article. I'd be open to discussing this with other editors if they'd care to take part, but otherwise, being printed in a NYT article certainly gives it enough notability. You say the article would expand dramatically. Can you give me an example of a misconception for one of the demographics you cite which is equally well sourced but which doesn't belong in the article?

2.5) The NYT article says "Nearly every Jew, from those who go to synagogue only on holidays to those who dutifully follow Jewish law, has heard that adage. It has deterred many from being inked". That seems fairly clear. But I also provided 3 more that use the exact phrasing you requested. The Orthodox Union says "This misconception is widespread amongst American Jews. References to it are often found in general American culture". To be clear, are you objecting because you don't think this idea is common, or because you don't think it's a misconception, or because you don't think the sources are reliable?

3) My point was about your standards of inclusion, but I'll sidestep this issue for now since it doesn't pertain directly.

4) I'll have to remind you that consensus is note a vote. Further, what you claim happened isn't what happened. I'm doing my best to keep this discussion from becoming contentious, but you'll have to help me with that. I'll leave the question on 2.5 open if you decide to come back to the article. All the best, Jess_talk|_edits 18:33, 6 January 2011 (UTC)

"if it's a "common misconception among Jews", that still makes it worthy of inclusion in the article" So every misconception held by any specific group of people is acceptable? Common misconceptions among Quakers. Common misconceptions among Druids. Common misconceptions among Choctaw Native Americans? No"

And yet the entry on Koreans believing in "fan death" is acceptable? 74.185.250.211 (talk) 19:16, 6 January 2011 (UTC)

The problem is that these aren't common misconceptions among Jews. They are commonly believed to be misconceptions by Jews. Very few Jews believe that some Jews only have sex through a sheet. There is a difference between a common misconception and a what is frequently believed to be common misconception. --Leivick (talk) 19:30, 6 January 2011 (UTC)

There are multiple edits on the table here... so we have to be careful to discuss them individually. I get the impression that Cresix has been claiming that, at best, the tattoo myth is common among Jews. However, the "sex through a sheet" myth is sourced as being common among non-Jews. With that cleared up, do you have a problem for the current sourcing for either of the tattoo or sex through a sheet misconceptions? Here are both:

• Orthodox Jews do not have sex through a hole in a sheet, as portrayed in various films and tv programs such as Curb Your Enthusiasm and A Price Above Rubies. In fact, according to Rabbi Shmuley Boteach, "Jewish law does not allow any articles of clothing to be worn during lovemaking", and using a sheet in this way could be considered a violation of that law.
• A person with a tattoo is not generally forbidden from being buried in a Jewish cemetery. This common misconception was depicted in the tv shows Curb Your Enthusiasm and The Nanny. While private cemeteries have the right to forbid burial on any grounds, there is no Jewish law to bar tattooed applicants, and it is uncommon to do so.

Jess_talk|_edits 20:16, 6 January 2011 (UTC)

I'll respond with a couple of comments and then leave for a while. Jess, it's you who put things in heated territory by edit warring with no consensus. So take your own advice. Second point: Sorry but you are flat wrong that re-adding (and let's skip the sugarcoating that it was reworded) disputed material in the midst of a consensus debate is acceptable. I've seen editors blocked for it on a number of occasions. And finally (for now) Jess, your "I have consensus" argument (invalid in the first place) is kaput. And I never said consensus is a vote; please stop throwing around ancient platitudes; it's insulting to the rest of us. But there is no such thing as a consensus of one editor; and now you have even more opposition. There is no consensus. I'm out of her for now. I'll be back for the cleanup later. Cresix (talk) 20:38, 6 January 2011 (UTC)

Cresix, I'm not going to engage this here, because where it's going is not appropriate for this talk page. If you have an issue with my editing, you are welcome to take it to my talk page or a noticeboard. That said, I would much appreciate it if you stopped claiming I was edit warring. Adding material once is not edit warring in any sense of the word, and misrepresenting my actions and intent in the ways you are is disingenuous. I'm doing my absolute best to work constructively with you - when you asked for more sources, I provided them. When you asked for sources with exact wording, I provided those. When you objected, I asked you why. It's becoming very difficult to continue in that way, and I really have to ask again that you stop treating this discussion like it's a battleground. Any further inquiries regarding editors should be taken off this page. If you could respond to my queries above (notably 2.5), that would be appreciated. Jess_talk|_edits 20:47, 6 January 2011 (UTC)

Once? Let's see . . . once . . . twice. Hmmm . . . oh that's right! You explained it on your talk page: "not sure how that happened, perhaps some silliness with edit conflicts". It's not edit warring . . . it's silly edit conflicts. At this time I'm not "responding to your queries above" because (1) responding to you doesn't seem to change anything, and (2) I'm avoiding this talk page for the most part right now. I'll be back at a future time for the cleanup. Cresix (talk) 21:53, 6 January 2011 (UTC)

Ok, so you're objecting to the content being added, but when I ask why you're objecting, you refuse to explain. I'm sorry, but that's not appropriate. If you decide to come back to the article and actually explain why it is that the proposal should not be included, then I'll be more than happy to work with you to fix it up. Until then, I don't see any standing objections to the tattoo bit being included in the article, so I'm going to reintroduce it. If another editor has an outstanding objection they haven't voiced, please revert me and discuss it here. All the best, Jess_talk|_edits 22:18, 6 January 2011 (UTC)

Wow... had no idea such a small thing would become so contentious -- Not sure how to further back up that these are common misconceptions, other than anecdotally and via Yahoo answers (1 , 2 , 3) as a very loose survey, with the agreement that the sex one is more prevalent among non-Jews, and tattooing being believed by a large percentage of non-religious Jews. Cresix, are you writing from a locale with a slight or nonexistant Jewish population? If so, that could easily explain why you've never heard these; if you rarely ever met a Jew, you would have no reason to have the subject ever arise. Anyway, didn't mean to cause a war here.

In the secion "Biology," we see "Bats are not blind. While most bat species do use echolocation to augment their vision, all bats have eyes and are capable of sight.[124][125][126]"

It might be more accurate to say "all species of bat have eyes and are capable of sight" instead, since surely not *every* bat in the world is sighted.

Addition request: Schizophrenia

Could somebody please add the misconception about schizophrenia and multiple person(ality) disorder? Request it because i'm not natural english speaker and don't want to leave a mess of language here ;) --84.61.4.67 (talk) —Preceding undated comment added 21:57, 5 January 2011 (UTC).

 Not done: Please provide a reliable source that this is a COMMON misconception. Cresix (talk) 21:59, 5 January 2011 (UTC)

The last sentence of the second paragraph in the article on Schizophrenia says that schizophrenia and split/multiple personality disorder are "often confused in public perception" and provides a source for that statement. --74.84.88.99 (talk) 23:22, 5 January 2011 (UTC)

Japan and vending machines

I would like to consider adding that the belief that in Japan you can commonly buy little girls' used underwear in vending machines is actually false. This did actually happen at one point in the early 1990s, yes, but it was not "on the main streets in Tokyo" as I often hear people say. It was in one town, Chiba City, and at one pornography store in said city. There was also an immediate public demand that the underwear vending machines be removed, so it's not as though this is an accepted practice in Japan.

However, the reason I'm first posting it in Discussion instead of just adding it to the article is because I'm not sure whether this falls under the category of "misconception" and thought I'd ask here first. Xprivate eyex (talk) 22:57, 5 January 2011 (UTC)

Misconception, yes. Common misconception? I doubt it. Hairhorn (talk) 23:00, 5 January 2011 (UTC)

Well, I don't doubt it. I agree that this is a common misconception, but I base this opinion on personal experience from talking to a dozen or so individuals about this exact subject over the past 15 years or so. Go to any anime convention in the United States and ask around; you'll find that this is a prevailing view. I can't say there are any reliable sources stating explicitly that this is a common misconception, however. It certainly seems common among western fans of Japanese popular culture. ~Amatulić (talk) 23:05, 5 January 2011 (UTC)

Update: It isn't a misconception at all, it's still true: See the article on Snopes: http://www.snopes.com/risque/kinky/panties.asp ~Amatulić (talk) 23:06, 5 January 2011 (UTC)

• I don't need to add a reliable source as long as I place "citation needed" after it.
• If I repeat the same argument over and over on the talk page, that's as good as a reliable source.
• It's not important to actually read the article or talk page before making a suggestion.
• If I think it's a misconception, that makes it a common misconception.
• If it's mentioned on a website, that makes it a common misconception.
• Several people told me they believe it to be true. That makes it a common misconception.

Galileo was not sentenced to death

Related with the discussion above --> Chapter 8 in: Ronald L. Numbers (ed.) Galileo Goes to Jail, and Other Myths about Science and Religion (Cambridge, MA: Harvard University Press, 2009). addresses the myth "That Galileo Was Imprisoned and Tortured for Advocating Copernicanism". In the concluding thoughts, it says:

In view of the available evidence, the most tenable position is that Galileo underwent an interrogation with the threat of torture but did not undergo actual torture or even territio realis. Although he remained under house arrest during the 1633 trial and for the subsequent nine years of his life, he never went to prison. We should keep in mind, however, that for 150 years after the trial the publicly available evidence indicated that Galileo had been imprisoned, and for 250 years the evidence indicated that he had been tortured. The myths of Galileo’s torture and imprisonment are thus genuine myths: ideas that are in fact false but once seemed true—and continue to be accepted as true by poorly educated persons and careless scholars. (p. 78)

I think you are confusing scientists. Galileo was threatened with torture by the church and imprisoned for life for his observations. Copernicus feared what would happen to him and waited until just before death until publishing.

However, Giordano Bruno was slowly burned to death by the church for his scientific work that suggest the Earth was not the center of the universe and the Sun is just one of many stars. http://en.wikipedia.org/wiki/Giordano_Bruno --Skintigh (talk) 19:23, 6 January 2011 (UTC)

Split?

This article has been growing consirabley today, no doubt because of the shout out in xkcd. I was thinking that we might want to split this article up and was taking a look at WP:SIZE. I estimate the readable prose length at about 75kb (actual size is 91kb) Currently the science section is the longest and could be split off into its own article. Any thoughts? --Leivick (talk) 23:49, 5 January 2011 (UTC)

If this article is split, then it will also need to be renamed to "List of lists of common misconceptions", since the actual content will be moved to other pages such as "List of common misconceptions in science" and "List of common misconceptions in history". That said, I support such a move. Not only would it make it easier to find things, but it would help disperse the current XKCD traffic. --MarkGyver (talk) 18:54, 6 January 2011 (UTC)

Dubious Deletions

Multiple editors have been deleting sections of this article on the basis of there not being a source showing that it is a misconception or there not being a source showing that it is a common misconception. These deletions have, in some cases been made without regard to ongoing discussions on the talk page concerning those exact issues.

If the issue is whether the alleged common misconception is true or false, a good policy is that if the section has been in the article for a long time but unsourced or has a low quality source such as an opinion on a blog, remove any low-quality sources and add a citation needed tag. If it was just recently added, deleting it with a note that it was unsourced or poorly sourced is appropriate. Editors are reminded that "Citation Needed" notices, unless many months old, are not a reason to delete a section.

An open question s whether it is reasonable to expect a citation from a reliable source showing that something is a common misconception. A reliable source saying that X is false and Y is true is evidence that X is a misconception, but not evidence that X is a widely held misconception It is hard to see how anyone could know that for sure without conducting a public opinion poll. I would favor discussing proposed deletions based on how commonly held the belief is on the talk page and seeking consensus rather than simply deleting them out of hand. Guy Macon 22:09, 5 January 2011 (UTC)

I just noticed a discussion about these very issues under the rather non-intuitive title "Snopes vs. LoCM". Guy Macon 22:13, 5 January 2011 (UTC)

I would be surprised to see you citing a wikipedia policy that states "unsourced material may not be deleted because people jabber about it on a discussion page" In fact, many templates state the opposite: "unsourced and challenged material may be removed." That's what people do and it is good and well they do it. It is, after all, not an issue to reinsert deleted content from a previous version IF someone actually comes up with sources AFTER a lengthy discussion (which I yet have to see, btw). But then again you are posting this at the top of the page which says a lot about the policies you follow ;) --Echosmoke (talk) 22:44, 5 January 2011 (UTC)

Please assume good faith. In this case the assumption is accurate; if I have failed to follow a policy it is because I don't know the policy. A link to the policy you are assuming I violated in bad faith would result in me studying the policy and doing my best to follow it in the future. Guy Macon 03:01, 6 January 2011 (UTC)

I can't fault the people editing this article for shooting first and asking questions later. They should still make sure that the questions do get asked. If an entry looks like there might just be good sourcing for it, the editor who removes it should bring it up on the discussion page if it isn't here already. Skipping this step means that the outcome is likely to depend on force, not facts, plus it's impolite. --Kizor 23:59, 5 January 2011 (UTC)

Three Magi are all men?

Has someone proven that Magi can only be male and that the Magi in the bible were 100% male? If not, why are we referring to them as wise men? Perhaps that can added as a common misconception.--Skintigh (talk) 00:03, 6 January 2011 (UTC)

• The primary source, Matthew 2:1-12 describes them as male ("wise men from the East came to Jerusalem") and was almost certainly referring to the (exclusively male) Zoroastrian priesthood. See Biblical Magi for more. - DustFormsWords (talk) 00:18, 6 January 2011 (UTC)

Thanks for the explanation. I don't think one should have to click on a link with no obvious purpose to gain an understanding of a Section heading. It seems like a form of in-talk. That's exactly the kind of thing that leads to common misconceptions. HiLo48 (talk) 01:51, 6 January 2011 (UTC)

It's a matter of where to draw the line on how popular something is. I don't think we have to explain what Google, FaceBook, YouTube, Twitter and CraigsList are for those who won't follow a link. XKCD, on the other hand, though quite popular, isn't on the Google list of the most popular websits worldwide (http://www.google.com/adplanner/static/top1000/), in the US (http://www.google.com/adplanner/static/top100countries/us.html), or the UK (http://www.google.com/adplanner/static/top100countries/gb.html).

Slavery and the US Civil War

I often hear (especially from folks from the Southern US) the claim that the US Civil War was not about slavery. Primary source documents from the time (articles of secession from the seceding states, the diary of prominent southerners like Alexander Stephens (VP of the CSA)) all emphasize slavery as the primary or sole cause for the war. --Thomas B♘talk 00:38, 6 January 2011 (UTC)

Like many wars it was probably really about property and profits. HiLo48 (talk) 00:42, 6 January 2011 (UTC)

It certainly was not the "sole cause" for the war; that's far too simplistic for such a complex topic. But I think most people would agree that it's the primary cause. The weakness of primary source documents from the time is that they lack the benefit of hindsight provided by time. Cresix (talk) 01:55, 6 January 2011 (UTC)

This is something taught in Southern schools, I guess to white-wash history. It's actually illegal in Texas to teach any history that portraits Texas in a negative light. While there were numerous reasons, the primary reason was slavery, and every state that seceded issued a proclamation of why the seceded and they all listed slavery as a primary reason. Perhaps we could gather each state's statement into one document and kill this lie once and for all. — Preceding unsigned comment added by Skintigh (talk • contribs) 18:07, 6 January 2011 (UTC)

Pyramid's Built by slaves

Various sources state that pyramids being built by slaves is a myth started a long time ago. 71.174.190.191 (talk) 01:37, 6 January 2011 (UTC)

Please provide sources that (1) the pyramids were not built by slaves, and (2) this is a COMMON misconception. Cresix (talk) 01:53, 6 January 2011 (UTC)

Our article Egyptian pyramid construction techniques says "Archaeologists now believe that the Great Pyramid of Giza (at least) was built by tens of thousands of skilled workers who camped near the pyramids and worked for a salary or as a form of tax payment..." So, not built by slaves. What's left is to demonstrate that enough people believe that they were built by slaves to justify labelling this as a common misconception. I suspect plenty do, but that pure OR on my part. HiLo48 (talk) 02:09, 6 January 2011 (UTC)

"This notion of a vast slave class in Egypt originated in Judeo-Christian tradition and has been popularized by Hollywood productions like Cecil B. De Mille’s The Ten Commandments, in which a captive people labor in the scorching sun beneath the whips of pharaoh’s overseers. But graffiti from inside the Giza monuments themselves have long suggested something very different." http://harvardmagazine.com/2003/07/who-built-the-pyramids

Edit request from Tyrkeybloke, 6 January 2011

The text: Palin actually said "They're our next-door neighbors, and you can actually see Russia from land here in Alaska, from an island in Alaska." is incorrect. The quote is wrong, and has been paraphrased by a news company.

The true quote is: "They're our next-door neighbors, and you can actually see Russia from land here in Alaska.", without the part on the end which was added to the news report which this article references. I distinctly recall the interview and the final part of the sentence as written in this article was certainly never spoken. I've tried to find the youtube link for the full interview, but I can only find the excerpt: http://www.youtube.com/watch?v=JXL86v8NoGk While it is cut short, you can clearly hear the interviewer jumping in with his next question right before the excerpt ends. I'm sure the full interview still exists, I just couldn't find the correct search terms.

On a separate note, I would argue that alongside other significant misconceptions relating to Christopher Columbus, George Washington, Abraham Lincoln, that a stupid comment by Sarah Palin is not of significant relevance to this article, and that countless other more significant examples could take that text space. I would propose the section be removed entirely.

Tyrkeybloke (talk) 02:18, 6 January 2011 (UTC)

Already discussed extensively on this talk page and in the archives. Cresix (talk) 02:24, 6 January 2011 (UTC)

And yet the entry is still there. I'd be happy for someone to rid us of it, I have already blanked it twice, so I'm disqualifying myself for now. Hairhorn (talk) 03:28, 6 January 2011 (UTC)

The additional explanation looks like the kind of thing that an interviewee would add when authorising the interview. Spoken speech is often a bit sloppier than written speech, so in English-speaking countries interviewees traditionally get a chance to edit their responses for the written version. Of course this also gets abused for making embarrassing mistakes sound more reasonable.

The claim that one can see something Russian from somewhere in Alaska is clearly true (see Diomede Islands, and that's not entirely theoretical since Little Diomede Island is inhabited (apparently by less than 200 Inupiat people).

The real issue here was the embarrassing insinuation that Russia being a neighbour of Alaska somehow makes her competent on foreign policy. It suggests very strongly that Palin has not reached the level of conscious incompetence about foreign policy and is still unconsciously incompetent. Apparently this blunder wasn't handy enough in the context of a US election campaign, so people on one side jumped on a caricature of the statement ("I can see Russia from my house").

Altogether, this is just another case of the picture presented in the media being an over-simplification of actual facts, although not completely wrong. It may be appropriate to explain this in detail in a Palin-related article, but as a mere simplification it's not really appropriate for this article and should be removed. Hans Adler 08:32, 6 January 2011 (UTC)

Exactly the points made in the previous discussion; this is here for polemic rather than educational reasons. So again I would call on someone to remove the entry. Hairhorn (talk) 22:12, 6 January 2011 (UTC)

"Rule of Thumb" Origin

Today, my government teacher told us that the origin of the phrase "Rule of Thumb" is that it used to refer to the maximum thickness of a stick with which a man was allowed to beat his wife. Being the smart-ass that I was, I immediately looked it up and found that this had been discredited. (See the Rule of Thumb page under the heading "Thumb used for regulation"). I would like to add the following (and its related references) to the LoCM:

It is often claimed that the term originally referred to a law that limited the maximum thickness of a stick with which it was permissible for a man to beat his wife, but this has been discredited.

But I do not know where this would be appropriate to go. Any suggestions? I'm a noob to editing Wikipedia so if anyone wants to do this instead of me, go right ahead. — Preceding unsigned comment added by Supergamesoftoday (talk • contribs) 03:07, 6 January 2011 (UTC)

I added it to the article under the "Law" section. Feel free to jump in and make any changes, or add any sources, which you have. Thanks for the suggestion! Jess_talk|_edits 09:47, 6 January 2011 (UTC)

I believe for proper clarity that the time period in which this myth was supposedly originated be mentioned in this article as taken from the cited writing which discredits this myth. Simply stating that it has been illegal since the 18th Century to beat your spouse opens up questioning as to laws before this time. However, the article cited makes mention of the colonial time period being the origins of this myth.

Essentially in this case, lack of proper quotation is lack of proper evidence making this section incomplete and partially invalid. Ivan0310 (talk) 14:34, 6 January 2011 (UTC)

I've heard this too, but always in the context of it being debunked. At the risk of stealing Cresix' thunder, "My teacher told me" is not the same thing as a reliable source stating this is a common misconception. 68.105.72.35 (talk) 16:54, 6 January 2011 (UTC)

Writing "In actuality, domestic abuse against women has always been illegal in the United States, and in Britain since the 1700s." without providing a citation is inappropriate. The term, "domestic abuse against women" is a culturally defined concept, and any claim that such action "has always been illegal" without consideration of the historical record of what has met the legal criteria for bona fide "abuse" and what has been considered culturally or civilly permissible is also inappropriate. —Preceding unsigned comment added by 98.206.163.9 (talk) 17:09, 6 January 2011 (UTC)

Edit request from F0r4n4, 6 January 2011

{{edit semi-protected}} For entry under Section 5.2 Human Body and Health of the page "List of Common Misperceptions"

The entry reads:

Vaccines do not cause autism.[114] Current scientific evidence does not support the hypothesis of causation for more-common disorders such as autism.[115][116] There is, however, significant biological evidence showing that mutations in the genes related to glutathione, a critical antioxidant involved in the removal of mercury from the body, are found to be significantly more common in people with autism. [117][118][119][120][121][122][123]

My proposed change:

Vaccines do not cause autism.[114] However, according to the National Autism Association, and a legal case involving the CDC and Hannah Poling; thimerosal – a leading preservative used in multi-use vials for childhood vaccines does. This is a failure in the manufacturing process as opposed to a failure in the safety of vaccines. The additional cost associated with producing single-use vaccine vials that do not require preservatives such as thimerosal to guard against the introduction of bacteria from multiple needle punctures in a single vial will successfully neutralize the threat posed from heavy metal neurotoxicity in children.

Reason for requested change:

The debate on Autism and vaccines is oversimplified in speech. Specifics were needed to convince the CDC during the hearing of Hannah Poling that there was merit to the claim of her parents. As such, the phrase "Vaccines do not cause Autism" is true, however, the claim that preservatives used in multi-dose vaccines are safe is false.

More than 5 senses.

Under the heading "Human Body and Health," it states that there are more than 5 senses. While this is in fact correct, I would like to note that some of the other senses listed, such as relative temperature, pain, itching, and even the urge to urinate are all caused by touch. This seems fairly obvious to me. 98.16.208.55 (talk) 06:24, 6 January 2011 (UTC)

I think you are confusing touch with physical contact. 111.69.248.240 (talk) 11:10, 6 January 2011 (UTC)

They are sensed by different kinds of nerves. Ultimately it comes down to semantics, and biologically it makes at least as much sense to count them as different senses as it does to throw them into one category called "touch". 68.105.72.35 (talk) 16:59, 6 January 2011 (UTC)

Speaking about senses, you should also include the perception of polarization of light discovered by Heidinger, see Haidinger's_brush. The ability to detect polarization provides additional information that can be used to detect position of the Sun even if it is covered by coulds.

A few more

Here are a few more that I would like to see added. I may add some of these myself, if time permits:

• Alexander Graham Bell did not invent the telephone.
• there is no good evidence that foods such as chocolate increase acne, according to my internist and a dermatologist I once saw. I'm going to look for more evidence to support this.
• pre-ejaculatory fluid has never been proven to contain sperm. rather, sperm that already exists in the urethra can be carried out by this fluid. if no sperm is in the urethra (for example, due to urination), pre-ejaculatory fluid can not cause pregnancy.
• America was not founded on Christian values, it was founded on Enlightenment Era values.

64.203.5.246 (talk) 09:03, 6 January 2011 (UTC)

I recommend against most of these. To take them point by point:

• "Bell did not invent the telephone" is at least as wrong as "Bell invented the telephone." The actual situation is rather complicated: http://en.wikipedia.org/wiki/Elisha_Gray_and_Alexander_Bell_telephone_controversy. There's substantial evidence that Bell may have been aware of Gray's work, but the fact is that Bell submitted a patent for the telephone, and Gray did not (until much later, when he submitted a patent for a crucial part of a telephone, not the telephone itself).

Science and religion: "No scientist ever lost his life..." and Lysenkoism

While it may be true that the Inquisition did not execute any scientists due to their scientific beliefs, scientists have in fact been killed because of their belief in Mendelian genetics under Stalinism. While the excuse for their executions or imprisonments leading to death was that they were spies or sabotuers, as with other purges and show trials of the time the real reason was political, in this case their opposition to Lysenko's botanic theories.

Miranda rights

Would it be appropriate to add an entry on the misconception that, in the US, if a suspect is not read his Miranda rights he is automatically freed? Seems a pretty common misconception to me, though, as with many such things, it may be difficult to source how common it is. In reality, such a failure only means that anything the suspect says afterwords (such as a confession) can be ruled inadmissible in court. All other evidence, including eyewitness, material evidence, etc. is still admissible and can lead to a conviction. -R. fiend (talk) 14:03, 6 January 2011 (UTC)

2012

The Maya calendar does not predict that the world will end in 2012, or in any date for that mater. This is simply the first day of the 14th b'ak'tun. In fact, Maya texts mention dates beyond this one. One extreme example is a data 41 octillion years in the future. (source for octillion date: http://en.wikipedia.org/wiki/2012_phenomenon#cite_note-S.26F-19)

All of this is well-documented here: http://en.wikipedia.org/wiki/2012_phenomenon

RELIABLE SOURCES: "Sandra Noble, executive director of the Mesoamerican research organization FAMSI, notes that "for the ancient Maya, it was a huge celebration to make it to the end of a whole cycle". She considers the portrayal of December 2012 as a doomsday or cosmic-shift event to be "a complete fabrication and a chance for a lot of people to cash in."[14] The 2009 science fiction apocalyptic disaster film 2012 is based on this belief. http://en.wikipedia.org/wiki/Maya_calendar#cite_note-13

POPULAR BELIEF NASA (http://en.wikipedia.org/wiki/2012_phenomenon)

Many movies help to popularize the idea that the Maya thought the world would end in 2012 : In the Will Smith movie “I Am Legend” the setting was 2012. The latest Indiana Jones feature theorized that the world would end if all the crystal skulls were not collected by that date. The movie Death Race (the new one, not the classic) references 2012 as the year that the economy fails. One major movie, titled “2012: The War For Souls” is a Michael Bay production based on Communion author Whitley Striber’s book of the same name. The 2009 movie simply called 2012 stars John Cusack and Amanda Peet and is a science fiction apocalyptic disaster film 2012 is based on this belief. http://en.wikipedia.org/wiki/2012_(film) — Preceding unsigned comment added by Pedrorui (talk • contribs) 14:35, 6 January 2011 (UTC)

Origin of the word "sushi"

The article asserts "The term sushi actually comes from the rice used, sumeshi, ..." and cites the webpage http://recipes.howstuffworks.com/menus/sushi.htm as its source.

There are at least two problems with that assertion.

1) The cited webpage DOES NOT currently say that, so it cannot be legitimately cited as a source for this information.

2) It is simply not clear that this is true etymologically. None of the kanji in question strongly lend themselves to this derivation. No etymological history that I am familiar with makes a clear and convincing case that this is true; in fact, I cannot think of any strong source even makes this claim, although I seem to remember seeing it in at least one popular source. —Preceding unsigned comment added by 128.186.122.174 (talk) 15:17, 6 January 2011 (UTC)

Science/Religion Compatibility... equivocation

The discussion of it being a "misconception" that Science and Religion are incompatible, relies on an equivocation about all three terms: Science, Religion, and compatibility.

For detailed discussion of this by Jerry Coyne, please reference this article. However, my basic point would be to ask that it be made abundantly clear: There IS and will remain an intractable incompatibility between scientific thinking/epistemology with regards to the falsifiability of hypotheses, standards of evidence, and the necessary modification of theories to accommodate/explain evidence

AND

Religious, dogmatic thinking that makes a virtue of faith (belief without evidence), and protects pre-existing beliefs at the expense of new knowledge.

Religious thinking and scientific thinking about "truth" in the world are fundamentally incompatible, and the common misconceptions page should be edited to clarify this. — Preceding unsigned comment added by Folboteur (talk • contribs) 17:01, 6 January 2011 (UTC)

The entire "Science and Religion" section is more controversy than misconception and should be relocated or removed. Large portions of it are inaccurate (the Flat Earth model was supported in Europe by respectable scholars, such as the Archbishop of Seville, well into the Middle Ages), debatable or matters of opinion. ArcheoPhyte (talk) 19:21, 6 January 2011 (UTC)

Let me add here that the basically one source, bloatet into 5, absolutely sucked. Past tense because I removed the entire thing after actually reading the source(s). Some of it certainly could reenter, better worded, more detailed and better sourced. Like, most likely "the church" did not hamper all or even most research (scientific or not), but is that what "people" imply when "they" say what they supposedly say (which has not been established by a source anyway). --Echosmoke (talk) 22:26, 6 January 2011 (UTC)

A majority of this section requires citations, with more assertions requiring them than have sources (which are dubious but I'm not qualified to refute properly). As mentioned above - this is more controversy than proven misconception and should not be on this page. It is more apologetic than factual. --BTolputt (talk) 00:54, 7 January 2011 (UTC)

Acronym etymologies

Would it be worth including a general comment along the lines that any word origin story that claims a word existing before the 20th century derives from an acronym is almost certainly false? Such etymologies are fairly common generally, even if individual ones (e.g. Fornication Under Consent of the King, For Unlawful Carnal Knowledge) may not be all that widely known. http://www.etymonline.com/baloney.php is an article debunking a particular one (Ship High In Transit) that also mentions the commonality of such false etymologies and supports the contention that acronyms were not at all in wide use before World War II and were practically unknown prior to World War I (the ones it does cite from prior to that are, with the exception of "okay", clearly abbreviations rather than actual words... we read 1:00pm as "one pee em", not "one pum"). 68.105.72.35 (talk) 17:42, 6 January 2011 (UTC)

That "S.O.S" stands for "Save Our Ship" could be another. I think that misconception is substantially more common than For Unlawful Carnal Knowledge or Ship High In Transit. -R. fiend (talk) 20:26, 6 January 2011 (UTC)

Dipping a sleeping person's hand in warm water does not cause them to involuntarily urinate

There is a commonly told summer camp prank that if you dip a sleeping person's hand in warm water, they will wet their bed. This myth was tested and debunked by the MythBusters show (2009 season, series episode #136 - http://en.wikipedia.org/wiki/MythBusters_%282009_season%29#Camp_Prank).

Do others think this qualifies as a common misconception?

Jhyrman (talk) 18:45, 6 January 2011 (UTC)

Personally, I think it probably does... but we'd need a source for it. Can you find a reliable source which specifically calls it "common"? Jess_talk|_edits 18:54, 6 January 2011 (UTC)

Not a cite, but a suggestion: perhaps we could reasonably agree to call any belief the Mythbusters consider worth debunking "common". I'm not suggesting that we make this a "List of things Mythbusters has debunked", just saying that mention of a particular belief on a national science-oriented show should perhaps count as a cite from a reputable source that the belief is at least moderately widespread... otherwise, what are we left with? I somehow can't see Gallup conducting a poll to determine how many people are worried about warm-water induced urination. Ptorquemada (talk) 19:35, 6 January 2011 (UTC)

If we start listing things from Mythbusters here, it will quickly open for us to list everything from Mythbusters here, which would probably result in creation of a "List of things Mythbusters has debunked" page anyway. Some guy (talk) 00:40, 7 January 2011 (UTC)

Timekeeping

This section is wildly off-base. None of the three references it cites state that it is a "misconception" that the numbered centuries and millennia begin in years ending in "1." And if it is a misconception, someone better send a memo to the rest of Wikipedia: 20th century, 2nd millennium, etc. This smells of original research and agenda-advancement via editing. Every authority on timekeeping and calendars I have ever consulted has been perfectly clear on the fact that, under the Gregorian calendar, the 20th century ran from 1901-2000. Will any editor step forward and produce an authority that says otherwise? (ISO 8601 doesn't even define centuries, so no soap there.)

You can say that the Gregorian calendar is "only a convention, man," to which the only possible response is yes--and so what? All definitions are conventional. You might as well say that it's a popular "misconception" that this comment was written in the year 2011. --158.111.5.34 (talk) 18:56, 6 January 2011 (UTC)

Strongly support removal. The section as currently included in the page is at least misleading and arguably wrong. The existence of some alternative system that nobody actually uses (if you disagree, please provide cites showing this usage to be widespread, not merely showing that such a system does exist) does not mean that the system that everybody actually DOES use is now invalid. In the Gregorian calendar new decades/centuries/millenia do in fact start on years ending in 1, not years ending in zero. Ptorquemada (talk) 19:28, 6 January 2011 (UTC)

I also strongly support removal of this section, it is completely at odds with many other articles in Wikipedia - Gregorian calendar, Civil calendar, etc. The ISO 8601 standard that it quotes is a standard for exchange of date and time information, it is not a calendar. Please either support with acceptable references (unlikely to happen!) or remove. Andreclos (talk) 22:58, 6 January 2011 (UTC)

Pluto as a planet

Might it be worth including the very common misconception (for cites, see Wikipedia's own article on Pluto) that Pluto was a planet until it somehow got "demoted"? Pluto is not now and never has been a planet. It was thought to be one for about sixty years, until scientists realized it was much smaller than they had thought (My CRC Handbook of Chemistry and Physics from 1982, for example, lists its estimated volume as about 70% of Earth's, when we now know it's less than 0.6%), not unique or even the largest of its kind, and that if one was going to draw a dividing line between, say, Ceres (which nobody considered a planet) and Neptune (which nobody considered NOT a planet), Pluto very definitely belonged on the Ceres side of the line for a number of very good reasons (size, orbit, non-uniqueness). This has been characterized (on this very page) as a "haughty" decision, but in fact it's simply a matter of "we messed up back in 1939, and now that we know better, we're finally getting around to fixing that." Ptorquemada (talk) 19:03, 6 January 2011 (UTC)

I'm not convinced this belongs. AFAIK, the public understanding was that Pluto was considered a planet, and now it is no longer considered a planet. That seems to be exactly what happened within the scientific community. If there was a common belief that, say, Pluto was miraculously blown into pieces and that's why it's no longer a planet, that would be good to include in the article. As it is, if there is indeed a misconception, I think it's just a semantic one. Jess_talk|_edits 19:31, 6 January 2011 (UTC)

Pluto was, in fact, a planet. I can cite books published before September 13, 2006 that say "Pluto is a planet". Those books are not wrong. "Planet" is a somewhat arbitrary designation that was changed somewhat arbitrarily. - JefiKnight (talk) 02:53, 7 January 2011 (UTC)

Giordano Bruno's demise

Under the Science and Religion section, the statement beginning "No scientist ever lost his life because of his scientific views..." is inaccurate. It may be true that Bruno's support for Copernicanism was not the principle reason for his execution, or even a contributing one. However, one of the principle charges against Bruno was his heretical belief in the plurality of worlds (see the Wikipedia entry for Giordano Bruno and references therein). Bruno held that the sun was merely one of many stars, the Earth but one of many planets and possibly that humans were but one of many forms of intelligent life. Bruno offered a partial recantation, eventually appealing to the Pope, but the head Inquisitor demanded a full recantation and found him guilty of heresy when he refused.

Bruno's religious beliefs and his apparently near limitless capacity for p*ssing off powerful political figures certainly were major factors in his fiery doom, but his scientific views were a contributing factor.

This statement is at best Controversy, not Misconception and should be relocated or removed. ArcheoPhyte (talk) 19:05, 6 January 2011 (UTC)

If what you say is true, then I agree. Are there specific reliable sources which can back up the notion that his scientific views were a contributing factor in his execution? Jess_talk|_edits 19:36, 6 January 2011 (UTC)

Hi Jess. I'm getting most of my information from the Wikipedia page on Giordano Bruno. The references are largely hardcopy and likely in Italian or Latin and thus inaccessible to me, so I'm relying on the author's of that page. The following excerpts from his wikipedia entry show that Bruno's belief in a plurality of worlds was a contributing, and possibly major factor in his demise (Emphasis mine in all cases):

"Still, the English period was a fruitful one. During that time Bruno completed and published some of his most important works, the "Italian Dialogues," including the cosmological tracts La Cena de le Ceneri (The Ash Wednesday Supper, 1584), De la Causa, Principio et Uno (On Cause, Principle and Unity, 1584), De l'Infinito Universo et Mondi (On the Infinite Universe and Worlds, 1584) as well as Lo Spaccio de la Bestia Trionfante (The Expulsion of the Triumphant Beast, 1584) and De gl' Heroici Furori (On Heroic Frenzies, 1585)."

"When Bruno announced his plan to leave Venice to his host, the latter, who was unhappy with the teachings he had received and had apparently developed a personal rancour towards Bruno, denounced him to the Venetian Inquisition, which had Bruno arrested on May 22, 1592. Among the numerous charges of blasphemy and heresy brought against him in Venice, based on Mocenigo's denunciation, was his belief in the plurality of worlds, as well as accusations of personal misconduct."

"The numerous charges against Bruno, based on some of his books as well as on witness accounts, included blasphemy, immoral conduct, and heresy in matters of dogmatic theology, and involved some of the basic doctrines of his philosophy and cosmology. Luigi Firpo lists them as follows:

   * Holding opinions contrary to the Catholic Faith and speaking against it and its ministers.
   * Holding erroneous opinions about the Trinity, about Christ's divinity and Incarnation.
   * Holding erroneous opinions about Christ.
   * Holding erroneous opinions about Transubstantiation and Mass.
   * Claiming the existence of a plurality of worlds and their eternity.
   * Believing in metempsychosis and in the transmigration of the human soul into brutes.
   * Dealing in magics and divination.
   * Denying the Virginity of Mary.

In these grim circumstances Bruno continued his Venetian defensive strategy, which consisted in bowing to the Church's dogmatic teachings, while trying to preserve the basis of his philosophy. In particular Bruno held firm to his belief in the plurality of worlds, although he was admonished to abandon it. His trial was overseen by the Inquisitor Cardinal Bellarmine, who demanded a full recantation, which Bruno eventually refused. Instead he appealed in vain to Pope Clement VIII, hoping to save his life through a partial recantation. The Pope expressed himself in favor of a guilty verdict. Consequently, Bruno was declared a heretic, and told he would be handed over to secular authorities."

I hope this helps. ArcheoPhyte (talk) 22:56, 6 January 2011 (UTC)

Edit request for "Evolution"

The first portion of the current article is currently written uses a bandwagon fallacy concluding validity of evolution which is not supported by the listed sources of the article.

Please revise to say the following which does not contain the fallacy, and is supported by its current sources:

The word “theory” in the “theory of evolution” does not necessarily imply doubt. The colloquial usage may denote a hunch or conjecture but in the scientific process it is much more. In this case “theory,” or hypothesis, is a concept that is not yet verified but that if true would explain certain facts or phenomena; once the idea survives experimental testing it becomes a scientific theory. [149][150] The “theory of evolution” is a scientific theory that has been observed, tested and has very little doubt associated with it. Evolution is a theory in the same sense as germ theory, gravitation, or plate tectonics.[151]

Modernhobo (talk) 19:44, 6 January 2011 (UTC)

• A theory isn't the same thing as a hypothesis. And using the term "verified" with scientific theories also gets you into muddy territory. Hairhorn (talk) 19:48, 6 January 2011 (UTC)

Pure Water

the following sentence was recently removed on the grounds that the editor did not see how it was a misconception: "*Purified water is not a good conductor of electricity.

The misconception is that people think that water is a good conductor, but it isn't. It is actually the impurities that are good conductors. 99.255.58.85 (talk) 22:05, 6 January 2011 (UTC)

Let me add once more. If you ask "people" "Is water a good conductor?" most will either say yes or no.

Under the heading, "Law," the following entry is invalid:

"It is frequently rumored that the expression "rule of thumb", which is used to indicate a technique for generating a quick estimate, was originally coined from a law allowing a man to beat his wife with a stick, provided it was not thicker than the width of his thumb.[39] This misconception was broadly printed in papers and media such as The Washington Post (1989), CNN (1993), and Time Magazine (1983).[40] In actuality, domestic abuse against women has always been illegal in the United States, and in Britain since the 1700s.[citation needed]"

According to the wikipedia entry on "rule of thumb", linked to in that entry (http://en.wikipedia.org/wiki/Rule_of_thumb#Origin_of_the_phrase) the phrase absolutely originated earlier than 1700:

"The earliest citation comes from Sir William Hope’s The Compleat Fencing-Master, second edition, 1692, page 157: "What he doth, he doth by rule of thumb, and not by art."

Consequently, the last sentence does not make any sense. Based on the information contained in this entry, it is certainly not clear that this is even a misconception at all. (While it is possible that the attribution of the phrase may in fact be errant, there is no reason to think so based on this entry.)

To be clear, I am not submitting this as a "talk" entry because the reasoning contained in the entry is indisputably wrong. If the phrase was coined before 1700, the legal status of abuse of women in the 1700s is irrelevant; if no relevant justification is given for this being a misconception, it does not belong in the article.

I agree. I've removed the bolded section. If we could expand the section further with accurate context, that would probably be helpful too. Jess_talk|_edits 00:56, 7 January 2011 (UTC)

Removal of "Science and Religion" section

I tentatively decided to remove the "Science and religion" section, which was added yesterday in the mass confusion after the xkcd comic. The section contained three entries, all of which were opinions the editor in question felt were incorrect, whereas this page is for listing verifably false beliefs held by some significant portion of people or regularly spread through media. The first entry, "no scientist has ever lost their life because of their views," is almost laughable--how can anyone verify this statement? In the entire history of the enterprise of science, no one has ever been killed because of what they believed? The second entry claims that the Catholic Church has never attempted to suppress scientific thought, which is, again, an arguable opinion at best and historically false at worst. The third statement says that science and religion have never been in conflict with each other, which is once again an extremely arguable opinion. All three of these "misconceptions" use the same link as their citation--an opinion piece published by the Faraday Institute. Additionally, instead of simply removing or editing the section, someone decided to add a huge amount of citation tags (which is an xkcd community in-joke and was probably added by them), to the point that the section was not even readable because of [citation needed] every three words.

In short, this section was an opinionated mess that was added hastily and without debate, with only one questionable source backing up three very arguable statements that, even if true, are certainly not "common misconceptions." ShadowUltra (talk) 01:20, 7 January 2011 (UTC)

Good job. LWG ^{I done wrong? Let me know!} 01:27, 7 January 2011 (UTC)

This was a very misleading description of both the content of the section removed and the citations that were provided. I don't think you are acting in bad faith, but this justification for the removal is essentially an untenable straw man argument. Anyway, I think we can wait for the xkcd confusion to go away before further discussions. --Leinad-Z (talk) 02:08, 7 January 2011 (UTC)

Diamonds do not form from coal

Popular misconception answered on Answers.com and Yahoo Answers. Check answers 1, 2, 8 and 9 on Yahoo Answers, which are dead wrong, for helpful examples of the misconception. This popular misconception has been promoted by over-simplified classroom explanations of complex geological processes and may have been further popularized by a quote attributed to Henry Kissinger that “A diamond is a chunk of coal that is made good under pressure.”

Correct Answer:

Coal is an impure variety of carbon that is formed when decaying plant matter in a swamp or bog is shallowly buried beneath layers of sedimentary rock [1]. Small amounts of heat and pressure cause the plant matter to break down, liberating volatile compounds, however appreciable amounts of hydrogen, oxygen, nitrogen and sulfur are contained in coal in quantities depending on its grade [2].

Diamonds, on the other hand, form from relatively pure carbon under extreme pressure but, contrary to popular belief, relatively low temperatures [3, figure 4]. Diamonds may be formed by meteorite impact [4]or subduction of continental plates in continent-continent collisons[5] but these diamonds are typically microscopic and, in the case of continetal subduction, revert back to graphite before reaching the surface.

All of the diamonds that humans use are erupted from the deep mantle by exotic types of volcanoes known as kimberlites or lamproites [6]. The majority of these diamonds formed from carbon that was present in the mantle when the crust formed, but a small minority of eclogitic diamonds appear to have formed from carbon carried down on subducting oceanic plates, most likely as carbonate minerals or organic debris.

So coal forms in shallow sedimentary basins on the continents, whereas diamonds form 150 km below surface or deeper and there is no known mechanism for getting coal to that depth and back up again as a diamond. Moreover, coal forms from dead plants, and the youngest diamonds dated at present are a hundred million years older than the first plants to colonize the planet's surface [7, 8].

Edit request from Dcpelletier, 7 January 2011

{{edit semi-protected}}

Under the Christianity heading,

"The Bible does not say Jesus fell to his knees under the weight or strain of carrying the cross and therefore the cross had to be carried by another. It has been assumed that Simon of Cyrene was told by soldiers to carry Jesus' cross because of Jesus being unable to continue due to weariness and exhaustion. Three of the four gospels (the synoptic gospels) give an account of Simon of Cyrene being forced to carry Jesus' cross by soldiers (Matthew 27:32, Mark 15:21, Luke 23:26). None of the accounts mention Jesus falling to his knees or being unable to carry the cross himself."

The misconception described in this entry is not "Jesus didn't fall to his knees" (as it sounds currently), it is "The Bible doesn't explicitly say that Jesus fell to his knees." Below is my suggested revision.

"The Bible does not explicitly give a reason why Simon of Cyrene was forced to carry the cross for Jesus. Three of the four gospels (the synoptic gospels) give an account of Simon of Cyrene being forced to carry Jesus' cross by soldiers, but none of them specifically mention Jesus falling to his knees or that he was unable to carry the cross himself. (Matthew 27:32, Mark 15:21, Luke 23:26)."

This "list of common misconceptions" is completely backwards

This is supposed to be a "list of common misconceptions", but it is apparently list of facts. For example: one of the items on this list says "George Washington did not have wooden teeth." That is not a misconception. It should say "George Washington had wooden teeth". - JefiKnight (talk) 02:53, 7 January 2011 (UTC)

• Have a look at the talk page archives where this is discussed ad nauseam. Hairhorn (talk) 03:04, 7 January 2011 (UTC)

A casual search only reveals one topic in the archives. It seems to agree that the list is backwards and the idea of changing it has some merit. - JefiKnight (talk) 03:28, 7 January 2011 (UTC)

snowboarding / skiing (speed down the hill by weight)

The post about a heavier snowboarder or skier reaching the bottom being false is not necessarily false. the only time at which two objects of dissimilar geometry and weight fall at the same speed is in the absence of air currents. a VERY light person with a large jacket will reach the bottom of the slope significantly slower than a heavier person, because the force of wind pushing up the hill versus the force (mass * acceleration) going downhill.

to further illustrate my point, see what happens when you drop a feather and a bowling ball on your bedroom fan. the first statement is true (heavier objects fall with the same velocity as lighter objects, but it does not follow that when you add in the force of wind, it still happens that way). it is patently irritating that a "list of common misconceptions" wrongly identifies a misconception...—Preceding unsigned comment added by 24.6.0.78 (talk) 03:06, 7 January 2011 (UTC)

There are other concerns as well, including friction (which is related to weight). None of that really matters though, since the section was wholly unsourced. I already removed the entry - I believe prior to this section being posted - so we should be good to go. Jess_talk|_edits 04:35, 7 January 2011 (UTC)

mislinked citation

this citation is wrong. It's listed and displayed as 168, but goes to 167:

Although frequently repeated as fact, a penny dropped from the Empire State Building will not kill a person or crack the sidewalk if it strikes either one.[168]

Vegetables as complete protein sources

The section regarding the need to combine vegetables to receive complete protein intakes is poorly cited. The citation is a biased opinion article that is itself, poorly sourced. This 'misconception' is so widespread that some empirical evidence, or a reputed published article should be provided. To determine the truth of the misconception, it would be necessary to know the completeness of each food in a non-complementary paired diet; use this with the amount of each food eaten to calculate the total quantity of each amino acid absorbed; and compare this gram quantity to the recommendations. The source cited for this misconception simply asserts it is unnecessary to complement without giving any evidence. —Preceding unsigned comment added by 99.254.68.50 (talk) 05:25, 7 January 2011 (UTC)

Defibrillators and heart stops

I think one important and common misconception which should be added to the health section is that defibrillators (the things which paramedics use to give an electric shock to a patient's chest) are not used to start a patient's heart but to stop it! If paramedics encounter a patient without pulse, they never use a defibrillator although television would indicate otherwise. It's actually only used to stop a heart if it has e.g. difficult arrythmia and the heart is expected to start itself after using its own sinus rhythm. Naturally if someone's heart is already stopped, there's no idea in stopping it again.

If paramedics encounter a patient without pulse, they resuscicate (chest massage and mouth-to-mouth).
