pre-deletion discussion

You said you moved bigfoot to a disputed facts section. This section is not at disputed facts, it's not in this article, and it's not in controversy. So I guess I'm asking where is it?

Should a person or group religious view point be called a misconception ? Smith03 17:09, 20 Sep 2003 (UTC)

Yes. --Wik 17:35, Sep 20, 2003 (UTC)

Whether the "world was created in seven days" by God is an unfalsifiable hypothesis and a matter of faith. -- Smerdis of Tlön 01:07, 20 Sep 2003 (UTC)

The creationism v evolutionism argument over how the world was created is POV stuff Graham  :) 16:49, 20 Sep 2003 (UTC)

Creationism is as good a misconception as any. This is not "POV stuff". --Wik 18:09, Sep 20, 2003 (UTC)
I would have to agree with Grahama and ask Wik why he believes it to be NPOV. --Daniel C. Boyer 17:22, 28 Sep 2003 (UTC)
I agree with Wik, Creationism requires faith and has no evidence to support the theories stated in the Bible, whereas there is plenty of evidence to support Evolution and the Big bang. Creationism is POV stuff, because you have to believe in it. Evolution doesn't require faith, it has science to support it. Balazsh (talk) 15:02, 6 January 2008 (UTC)
I always hate when people say any scientific theory doesn't require "faith". Belief in evolution also requires a faith or trust in science, and that science fortifies that belief set. There is no way one person could have done all the experiments, performed all the research, etc, that support evolution, so some trust and faith of some people and/or some past historical events MUST come into play. I have faith that Darwin wrote "On the Origin of Species". Can I prove it? Yes and no, depending upon who I'm proving it to. If somebody believes the world really was created yesterday and that all of our local library content, Wikipedia, etc. is a pack of lies, I'm going to have a alot of trouble proving that fact to him or her. Creationism in itself cannot be a misconception because it is a belief in a different set of axioms. (Or more bluntly, it may require an additional set of beliefs that may have higher priority over some scientific beliefs). The misconceptions come into play when faith and evidence come into conflict. Either a person believes what is scientific, or they believe what is biblical (or they need to re-interpret either or both). Things on this page should be incontrovertible, based on plain and simple facts. Where belief systems are in conflict, the core conflicting facts should be made easy to see. When that distinction is made, we've truly made an NPOV statement. A quick scan over the Evolution and Christianity sections gives me the impression that our content is sufficient to this proposition, though a more thorogh study may reveal otherwise.

Deletion discourse

Deletionist: All the items in the list are POV - you can't write neutrally on this topic. Furthermore, they're not misconceptions: they're semantic disputes or disputed facts.

Inclusionist: But I can think of NPOV misconceptions, like the Mary Celeste or "play it again Sam". People will accept that they've got a misconception on being confronted with the full details.

Deletionist: Even if there are NPOV misconceptions, the article will invariably attract POV additions: it'd be a lot of work to make this thing neutral, and keep it that way.

Inclusionist: Perhaps, but I think it'd be worth the effort. This would make a fun entry point into a range of articles, and be educational to boot.

Deletionist: In the end, it just isn't encyclopedic now, and it won't ever be encyclopedic. Let's delete it and move on.

Inclusionist: I disagree: like a butterfly, this article will turn into something beautiful. Just wait and see.

Deletionist: Nearly every article in an encyclopedia has information that someone didn't know, or was incorrect about. These pieces of trivia belong in the articles about that subject, which is where encylopedia users will look for answers to their question. If they want to learn a random fact, they can click on Random Page.

Inclusionist: It's not stated, but this entry is about "common and widespread" misconceptions, not just all possible misconceptions. Students tend to always aquire the same misconceptions. "Education by debunking" is a valid technique, especially in gradeschool physics, and this entry brings it all together in one place.

Proposed move

If my rewrite of the article sticks (ha!) then I'd like to move this thing to list of misconceptions. Objections? Martin 00:33, 28 Sep 2003 (UTC)

No. But surrealism being an artistic movement is definitely simply a misconception, not a disputed fact. Nearly every primary source from surrealism's beginning to the present day makes this point directly, even in so many words, or indirectly, through its discussion of something completely separate from art, from its definition of surrealism, from its failure to say anything about art... This is not an honest dispute, this is not a controversy, this is a misconception plain and simple. --Daniel C. Boyer 17:24, 28 Sep 2003 (UTC)
I disagree- I dispute it. Kurt Schwitters was a surrealist writer and visual artist. Markalexander100 02:35, 7 Mar 2004 (UTC)

Physics

Some coments by Chris:

  • The information on bicycling is incorrect. Reading the paper from the Physical Review, one finds that the main argument of that paper was precisely the opposite of the way it was cited here. Somebody didn't actually read their sources. The rider finds it easier to steer a bicycle at high speeds: a direct result of the fact that angular momentum is a cross product, with a component that acts to push against any tilting. Higher speeds implies a higher angular momentum, whose lateral component will "push back" harder in response to a torque caused by tilting, the crux of what we describe as "gyroscopic" forces.

Some comments by Neo:

  • Gravity is actually the weakest of the four fundamental forces, at about 1 thousand trillion trillion trillion times weaker than the strong nuclear force.
    • Isn't this statement meaningless without defining both the objects, and the distance involved. At the largest scales (for instance of the order of parsecs and above) one can largely reject electromagnetic interactions, whereas one would be stupid to reject gravitational interactions. Similaly one can reject gravitational interactions at length scales of the order of nanometers, but one needs to consider electromagnetic interactions.
    • Is this even a misconception? If people know of the existence of the four fundamental forces, which is quite a high level physics concept (ask people on the street whethere they know what the strong nuclear force is...) then they know that for fundamental particles and small length scales the order of strengths differs from that at macroscopic length scales and for larger objects.
The interactions consider the strength of all charges yester they are added to near-neutrality, for a given mass and distance. Besides, you can still see stars from thousands, and galaxies from millions, of parsecs away—can you feel their gravity?? -lysdexia 00:52, 5 November 2006 (UTC)

Some comments by Dotchan:

  • I'm fairly sure that water is colorless; it looks blue because the microparticles in the water absorbs all other colors. (Note that the blue color doesn't become visible until one has waded out to a certain depth.)
Wrong! You've aquired a widespread misconception. Water is [definitely a blue substance], and the "microparticles" which cause the color are the water molecules.--Wjbeaty 20:06, 22 December 2005 (UTC)
No, you're wrong. Water is hueles but not huefree. -lysdexia 00:52, 5 November 2006 (UTC)

Some comments by tcsetattr:

  • Is there any justification for the statement "gravity reduces exponentially"? Sounded cooler than "quadratically"? Seems like "exponential" might be a good candidate for the List of frequently misused English words or (if it's too late) at least the List of English words with disputed usage Tcsetattr 05:53, 11 January 2006 (UTC)
    • Fixed. -- BenRG 03:41, 28 January 2006 (UTC)
    • To say "gravity reduces exponentially" is very wrong. If gravity reduced exponentially, it would reduce as a^(-r) (r is distance, r is a constant) instead of as r^-2. (I may be misunderstanding what your post originally meant, however). -Arkady
    • The Inverse Square Law applies. The strength of gravity between two masses (bodies) increases as the square of the distance, and therefore the strength of gravity between two masses decreases as the inverse of the square of the distance. Arkady's response (above) is correct. - afrab_null

Some comments by fafnir: 12:19, 10 October 2006 The magnetic pole stuff is meaningless. You can take any magnet, and lable the pole 'north and south' arbitrarily. The north pole is the north magnetic pole, little magnets people carry around and call compasses have the south magnetic pole on the compass painted red and labled 'north' so people know which direction is north. The only misconception is on the author's part. Though the poles have switched in the past, throughout man's history they have remained constant enough for countless people to use them for navigation and such.

  • Meaningless? Which part? I suspect that instead you just don't understand it. "North" and "south" are defined in physics and engineering, just as "positive" and "negative" electric charges are defined. The choice of course was arbitrary, but it was made long ago and is followed by the entire science community. In the same way, you can label electrons as "positive" if you really want, but you'd be sowing confusion by violating a century-old standard. Magnetism is the same: a century-old physics standard tells us what "north" pole means. Maxwell's equations are based on negative electrons, and on "N" poles which point to the Earth's northern hemisphere. According to this standard, the geographic north part of the Earth contains a "south" type of magnetic pole, and so the end of a magnet which points towards it must be a "north" pole. Any authors which say the opposite are wrong: wrong in the same way as if they had said that protons carry a negative charge. --Wjbeaty 08:27, 29 October 2006 (UTC)

in the section on electricty, the theory of relativity is quoted as to why electrons cannot move at the speed of light, but isnt that why we have quantum physics, because when you get down to atomic and subatomic particles, the theory of relativity no longer applies, hence the search for a uniform theory of realitivity, that works for both regular items and atomic and smaller particles? —Preceding unsigned comment added by 214.13.212.26 (talk) 05:21, 5 October 2007 (UTC)

Hosepipe:"It is not true that a nozzle (or a person's thumb) on the end of a garden hose makes the water squirt farther because of the Bernoulli principle. The pressure at the end of a hose depends very much on the speed of the water which flows through miles of pipe. ". I don't agree with this - i think simple force/area pressure. I don't have access to the reference, but there is: http://amos.indiana.edu/library/scripts/hose.html and https://www2.hcmut.edu.vn/~huynhqlinh/olympicvl/tailieu/physlink_askexpert/ae185.cfm.htm.

I'm also slightly concerned about a paragraph just about beginning "Due to Archimedes's principle,"; there are lots of details but no references, I'm feeling possibly politically motivated as it stands. Or, very interesting indeed if true.

Apologies for any poor wikiquette, I'm very new.--Davini994 (talk) 23:10, 7 January 2008 (UTC)

Some comments by smcanby:

  • Regarding "Hosepipe" above: Both references sited are fundamentally flawed by the fact that they assume that the RATE of water flow is the same with both a "squirting" and "non-squirting" hose.
  • It can be demonstrated by experiment that the RATE of flow is less for the "squirting" hose than the "non-squirting" by using a bucket and stopwatch. Time how long it takes to fill the bucket using the two methods (without changing the spigot). The "squirting" hose method takes longer.
  • There is another flaw in the reference https://www2.hcmut.edu.vn/~huynhqlinh/olympicvl/tailieu/physlink_askexpert/ae185.cfm.htm.: When the hose is turned on, water will be released, and will go a distance depending on this pressure and the opening area of the hose. (Partially WRONG) The distance that water will travel is dependent ONLY upon the pressure, NOT the opening area of the hose. This can also be demonstrated by experiment. Using a bucket, drill two holes of different sizes in the side at the same elevation from the bottom (e.g. a 5 mm hole and a 10 mm hole). Plug both holes with your fingers and fill the bucket (this may require an assistant). Unplug the holes and notice that although the larger hole has a higher RATE, both holes will "squirt" the same distance.

Health

In this article, it is told that cold weather can decrease the strenght of the immune system and thus facilitate the common cold. But in the "Old wives' tale" article, the opposite is told: cold weather and decreased immunity have no correlation. At least one of them is wrong.

Deleted the following: BEGIN

Colds and 'Flu

Main article: Common cold
  • Exposure to cold conditions, or the moving between cold and warm environments, is not a cause of the Common cold or Influenza. Moreover, the development of colds and 'flu are not encouraged by such exposure. Cold weather often forces humans to congregate indoors, which encourages the spreading of airborne viruses. (Long term exposure to cold conditions can, however, lead to Hypothermia, which is a much more serious problem)
  • Infection with a cold virus affects thermogenesis. This makes people associate post-infection shivering with situations in which they were exposed to cold that intensifies shivering (e.g. wet hair, draft, long wait on a bus stop, etc.). This association helps propagate the myth.
  • A cold virus often irritates nasal passages and encourages sneezing. Sneezing can also be caused by other conditions, notably exposure to colder air temperatures. Cold weather can thus cause sneezing, but sneezing is not necessarily an indication that a person has "caught a cold".
  • If cold weather were directly linked to the spread of the common cold, then it could possibly be demonstrated by comparing the infection rates of people who live in colder climates (such as Iceland or Greenland) with people who live in warmer climates (such as countries close to the equator). Studies done in the 1960s found no significant increase in infection rates in people who live in colder climates.
  • One reason why so many people link exposure to cold weather to "catching a cold" is via a logical fallacy which assumes that Correlation implies causation. Colds are certainly more prevalent during colder periods of the year, but it is wrong to assume that the two are directly linked.
  • The "Correlation implies causation" fallacy can also apply to popular treatments for colds and flu symptoms, whereby a sufferer associates their improving health to certain cold remedies, when in fact their improving health would have occurred with or without these remedies. Popular remedies can also have a "Placebo effect", whereby a person who believes in a certain treatment "feels" better as a result. Some of these popular treatment are:
  • Echinacea. Scientific studies into the effects of Echinacea have shown no measurable positive effect on those suffering from colds or 'flu.
  • Vitamin C. Vitamin C can reduce the incidence of colds amongst physically stressed people by up to 50%. Amongst ordinary people, a 200mg daily dose had no effect whatsoever in reducing the incidence of colds.
  • Zinc lozenges. A 1999 study showed that the effects of zinc lozenges for treating the common cold are inconclusive.

The above is original research, and also wrong, or at least heavily debated. From the common cold page: "a rhinovirus cannot survive at elevated temperatures for more than a few minutes.[8] Because of this weakness, the rhinovirus infects the outer membranes of the throat and sinuses, where it is not exposed to normal human body temperature."

In the winter, the extremities are more likely to be cold. Is it winter? Touch your nose. Bingo. Also:

"It is not known conclusively whether cold weather or a humid climate can affect transmission by other means, such as by affecting the immune system, or ICAM-1 receptor concentration, or simply increasing the amount and frequency of nasal secretions and frequency of hand to face contact."

"researchers at the Common Cold Centre at the Cardiff University attempted to demonstrate that cold temperatures can lead to a greater susceptibility to viral infection. In the experiment, 29% of a group of 90 people who sat with their feet in ice-cold water for 20 minutes a day for five days developed cold symptoms during the five days, while 9% of a control group of 90 people who were not similarly exposed developed symptoms."

This page is hardly the place for stuff that's open to debate. If scientists are still asking questions about whether it is the case or not, then it is clearly not a "misconception" it is "not yet established".

Also see http://www.medpagetoday.com/Pulmonary/URIstheFlu/tb/2136. This states that "many of us carry around a subclinical cold infection and that chilling the feet opens the door for it to become a full-blown cold.". So exposure to cold temperatures clearly does lead to one developing a cold. This clearly is not a misconception.

Why the sky is blue

Some believe that the sky looks blue because it reflects the ocean...

Who are those fools?! This is a list about "common misconceptions", not "misconceptions held by a tiny minority of people who probably think the moon is made of cheese as well".

I hope there aren't people who believe the sky over a desert is yellow, because it reflects the sand. Psychonaut3000 03:10, 14 July 2006 (UTC)

It is quite widespread. Explanation I was given as a kid was that the earth, in general, is a blue/white sphere when seen from space; the average colour is blue. In the same way Mars' atmosphere is thought of as red. (Note: the sky over the desert can well be yellower than that over the sea, due to dust particles, which to the naïve might appear to support the ground-reflecting hypothesis). DewiMorgan 12:18, 18 May 2007 (UTC)

I agree with Dewi here, this misconception is held by a surprisingly large amount of people, and so should still remain on the list, regardless of whether the initial theory sounds silly. --Balazsh (talk) 14:08, 6 January 2008 (UTC)

As well I don't think its accurate, I have read several good (historical, non-fiction) books on pirates and privateering and was always lead to believe that well the jolly roger was different in many ways from ship to ship it still existed.

Evolution

I want to propose merging the Evolution section with the Biology section on this same page. I am just unsure of how to format the template. The Evolution section might get a separate subheader but it really belongs under Biology. Cthompson (talk) 03:54, 1 June 2008 (UTC)

I love this page :) I added a whole swathe on evolution, but now I'm thinking maybe this should be copied to the evolution page itself. These misapprehensions about evolution are, so far as I can tell, the only reason it is not universally accepted. [edit: Oops forgot to sign]DewiMorgan 22:32, 26 May 2007 (UTC)

Thanks, but I'm going to try to pare down the list. As it is, it seems somewhat redundant and inaccurate. --Allen 03:30, 1 July 2007 (UTC)
I ended up only making some small changes... after doing that I think the bigger problem is that most of the points aren't shown to be common misconceptions in the first place (in fact, I think that's a serious problem with much of this article). I'll plan to wait a while and then remove points that don't have a source to demonstrate that they're misconceptions, unless it seems to me that they obviously are. --Allen 03:39, 1 July 2007 (UTC)
How I should prove the evolutionary misconceptions are such. I could link to many forum discussions on the topic where people are being blatantly wrong on each of the points, but I think that showing the poor people in those forums to be retarded would be immoral. I don't think there have been many scientific papers on what the common evolutionary misconceptions are, so I'm not sure that kind of references I should give. I guess maybe Intelligent Design sites? But the idea of using those sites as a reference, even as a reference for wrong-thinking, turns my stomach. As it is, as someone who has been in many discussions on evolution, I find it hard to tell which of the list are not "obviously" misconceptions: I've seen them all, countless times. Also, it seems that someone added a similar section to the evolutionary basics page, so I suspect that they are pretty common. DewiMorgan
One of the items in this section is unclear: "Evolution is a "theory" in the same way as the theories of gravity, thermodynamics, etc.", stated as fact, which I believe it is. It continues: ""The word "theory" has a different meaning in a scientific context than in a casual, which may have lead to this misunderstanding." The first part is another fact, but then the sentence ends referring to "this misunderstanding", but... what exactly is the misunderstanding? It's never mentioned. Retodon8 14:41, 4 July 2007 (UTC)
Good call - I prepended "Some believe that as Evolution is a "theory", it is merely a hypothesis, rather than a proven fact of life." to clarify. DewiMorgan 17:52, 4 July 2007 (UTC)

Made some changes. In particular, I returned the two sections:

  • Evolution does not happen within just one creature: you need the entirety of a population to observe evolution. You need some of them to breed, and some not to.

You hear this one so often it's painful: definitely a misconception/strawman, but which one to link to as a ref?

  • Evolution is not progress from "lower" to "higher". In that sense, "Evolution" is a misnomer.

Same again. Not so much a question of whether it's a misconception, but rather, link to use to show that it is?

Also did some cleaning up, added a link to http://en.wikipedia.org/wiki/List_of_misconceptions#Evolution and so on.DewiMorgan 18:47, 4 July 2007 (UTC)

Actually, there was a real article here at one time, a fork of evolution, called Misconceptions about evolution or something similar. It was deleted I believe, but still might be retrieved and mined potentially. Some of this material is ok, but some of it needs some editing and pruning and correction, in both the evolution section and the other sections.--Filll 16:26, 22 July 2007 (UTC)
  • Please clarify in the article what counts as a mutation in the following statement: The claim that "almost all mutations are harmful" is false. In fact, most mutations have no noticeable effect.

Spaghetti Bolognese

Spaghetti Bolognese did not originate in Italy. [citation needed]

This is not supported by the current article on SB or anything else I have ever read. Perhaps it is a confusion based on the well attested fact that "Bolognese sauce" is called ragu in Bologna.1Z 16:16, 12 August 2007 (UTC)

"Spaghetti bolognese did not originate in Italy. The actual name in Italian is spaghetti con ragù, which means spaghetti with ragù. Spaghetti bolognese is actually the German name." FALSE. First of all, the common way of saying is "spaghetti AL ragù" not "spaghetti CON ragù". Moreover, "ragù" is a meat sauce that can be done in many ways, and "ragù alla bolognese" is one of them. You can say "Spaghetti alla bolognese" (omitting the preposition is an error) to mean "Spaghetti (al|con) ragù alla bolognese". Writing from Italy, not that far from Bologna :) Barabba 14:05, 9 November 2007 (UTC)

Uncertainty principle

Would this article benefit from a discussion of the Heisenberg uncertainty principle, which is often misinterpreted to mean "everything is uncertain" is some sweeping way. 1Z 16:25, 19 August 2007 (UTC)

Coriolis formula

I have removed the formula from the section on the Coriolis force affecting bathtub draining.

  • The formula is for an object falling vertically; but weather, ocean currents, missiles and draining water move horizontally.
  • The equation predicts a maximum effect at the equator, λ = 0, whereas the effect on drains and weather would change sign (be zero) there.
  • The text makes the assertion that cosλ is a maximum at λ=1, which is false.

Native Americans/Aborigines couldn't see the Europeans' ships

What about adding this misconception - that 'uncivilised' peoples couldn't see the Europeans' ships because they didn't have the concept for it? I've heard this idiocy from various intelligent British people.Malick78 07:46, 10 September 2007 (UTC)

I don't think it's a common misconception, so probably isn't appropriate for this list. It's a misconception solely of those who've uncritically swallowed certain ideas from the postmodern cultural studies movement. Furthermore, as I'm British, I feel honour-bound to point out that this misconception is not by any stretch confined to the United Kingdom.  ;-) The article on the Sokal Affair should illuminate those less familiar with this particular streak of postmodern craziness. --Plumbago 07:59, 10 September 2007 (UTC)
