Protoscience or pseudoscience?[edit]

Here's what an angry reader said to the "authorized editors": --- What a stunning bunch of intellectually constipated wiki-fascists. How many centuries have humans KNOWN that we are just as susceptible and influenced by various cycles as everything else? You bunch of orifi have passed judgement on a subject much bigger than this page, your ability to discern truth from minutiae, and the purpose of Wiki. You should be ashamed of yourselves. I am disgusted with you, and shocked at the small minded turtle puppet club that edits Wikipedia. You have betrayed the idea of open information. I curse at you and spit between my fingers at your feet. -- —Preceding unsigned comment added by (talk) 05:07, 15 April 2011 (UTC) ALSO - you all discourse from the innate premise that "numeracy" is an unshakeable requirement for the understanding of any and everything in existence. IT IS NOT ! (snobs!)

This is not a protoscience becasue it has not changed much since it's inception and it Does not follow scientific protocolsGeni 11:02, 19 Aug 2004 (UTC)

It's clearly a pseudoscience. All the books I read about it are written by completely innumerate proponents. All the evidence they propose is based on math errors that give wonderful stories if you want to amuse mathematicians. The concept itself is a magical and numerological idea. --Hob Gadling 18:53, Mar 14, 2005 (UTC)

Hello, Sorry to barge in, not used to all this, but I saw need for a citation for the part about Dr. Rexford B. Hersey, and I just read an article. His work looks like genuine science. Citation would be, "Why We All Have 'Ups and Downs'", Condensed from Redbook, by Myron Stearns; copyright 1945 by The Reader's Digest Association, In.c, (December 1945 issue), condensed from Redbook, November 1945; the whole condensed version having appeared on pp. 131-134 of the hardcover book, "Getting the Most Out of Life" (collection of condensed articles),c.1955, The Reader's Digest Association, Inc.

Dr. Rexford B. Heresy was of University of Pennsylvania, studied the rise and fall of human emotions for over 17 years, collaborated with endocrinologist Dr. Michael J. Bennett of the Doctor's Hospital in Philadelphia. The first research lasted over a year, consisting of visiting four times a day each of 25 workers in a Railroad Repair shop; eventually over 5,000 subjects were involved. Looks for all the world like serious, scientific research, though I haven't seen the original source material.

Rhythm length[edit]

I changed "lasts around 23 days" to "lasts 23 days; same with 33 and 28. The reason:

If the first rhythm were 23.01 days (about a quarter of an hour more than 23 days), 100 rhythms (about 6 years) would take 2301 days instead of 2300. So, after 60 years, the rhythms would be 10 days off, and all the anecdotes used to defend biorhythms would be worthless. So it really has to be 23 days, plus/minus only very few minutes. Otherwise the whole body of "evidence" is inconsistent. Not noticing this is one of the many innumeracies of biorhythm proponents. --Hob Gadling 19:30, Mar 14, 2005 (UTC)

Too much content[edit]

Do we really have to have the fully "calculation method" in an encyclopedia? It should be removed if a good reason is not stated not to. -- 20:52, 18 July 2006 (UTC)

Biological ryhthms do exist in plants, animals, bacteria, humans, etc, (it's basically chronobiology) but the science is NOT what is described in this article (which is pseudoscience or numerology). This needs to be re-written with scientific content.

I think the calculation method is worth including for the simple fact that all information is of value, unless it is mis-information. However I have concerns about the neutrality of this article.

external links need to be cut down[edit]

Wikipedia isn't a link directory nor a place to advertise sites, so it's not really appropriate for an article to have 20+ external links, much less 10 nearly identical ones linking to different biorhythm calculators. --Delirium 13:05, 3 February 2007 (UTC)

Looks like it was taken care of; thanks! --Delirium 00:33, 4 February 2007 (UTC)

Study Shows Body Clock Affects Arthritis Pain[edit]

  • " Audio Article" Arthritis sufferers often feel more pain in the morning than in the evening. A new study explains these fluctuations are driven by the body's internal clock. Sydney Spiesel, a Yale Medical School professor and contributor to the online magazine Slate, talks with Alex Cohen. --Travisthurston 06:20, 12 April 2007 (UTC)
  • This is evidence of the Circadian rhythm affecting pain, not of the concept of biorhythms. The circadian rhythm relates to chronobiology, not this article. --Interested2 17:54, 1 May 2007 (UTC)



I am adding back the point in the intro about it being a form of pseudoscience. Biorhythms are obviously controversial and as such we should try to present a neutral point of view in the article that describes all opinions on the subject. The purpose of the introduction to the article is to give an overview of the subject, and as the question of its scientific accuracy is an important part of the article, I think it's relevant to mention the debate there. fraggle 07:51, 8 May 2007 (UTC)

In the section on plausability, the following sentence occurs: "The plausibility of biorhythmics is contested by mathematicians, biologists and other scientists." This is very vague, considering that the Biorhythmics section of the Research publications lists 3 papers specifically discounting "biorhythmics". In addition, the reference to chorobiology seems to largely exist to link biorhythmics (which seems to be a pseudoscience) with chronobiology (a recognised field of science). I think the distinction needs clarifying. pvanheus 21:14, 17 June 2007 (UTC)

I changed the first reference to Effects of circadian rhythm phase alteration on physiological and psychological variables: Implications to pilot performance (including a partially annotated bibliography) because the originally listed paper was merely quoting this one. However, I don't have access to that paper so I can't check the quote. Paul Sinnett (talk) 14:57, 30 May 2009 (UTC)

1970s Popularity[edit]

I remember this was something of a fad in the 1970s. The real significance here seems to be that biorhythms were a part of popular culture - perhaps that could be mentioned in the article if anyone cares to find references. —Preceding unsigned comment added by Johnelwayrules (talkcontribs) 01:56, 16 September 2008 (UTC)


Copied from my talk. The edit in question is here. - 2/0 (cont.) 06:56, 18 November 2009 (UTC)

Hi! I guess that's a better place to post my comment. Why did you remove product names and links altogether? I think it's not the way it should be! This is supposed to be an objective, factual, and modern encyclopedia. Biorhythm software is a major part of biorhythm application today! In fact software nowadays in the area of biorhythms is much more important than it used to be in the 80s when biorhythm were more popular. Thus simply mentioning it in one phrase generically does not suffice at all, in my opinion. Besides there is an enormous amount of articles that mention software and do include external links. For instance this is the article I came across yesterday - - and under PC Integration it mentions all major software products for DLNA and their external links! In that regard I see no reason not to mention 2 or 3 most popular and recent software products for biorhythms and external links to them. I certainly see your point that Wikipedia is not a directory; however the inclusion of links to prevaling software on a particular subject, in my opinion, by no means violates this rule. In fact, there exist so many pages on Wikipedia that actually compare different software in their functionality anbd of course include external links. Sure, biorhythm software is not as popular as say Photoshop, but it cannot be a reason to ignore it, because within the area of biorhythms, it is an important part of today's subject on biorhythms.--George (talk) 09:25, 17 November 2009 (UTC)

Reading that section of the article, it was my impression that the primary purpose seemed to be to drive traffic to a particular website rather than to edify our readers. Basically, we need to offer more information and deeper coverage than is available simply by scanning the first page of search engine results; almost as importantly, article content cannot be based on our own original research. Saying that a particular company offers the best biorhythms calculator or interface without citing a reliable source makes your text look like spam. - 2/0 (cont.) 06:56, 18 November 2009 (UTC)
Thanks for moving the discussion here. I certainly agree with you for the most part on that. However, in that respect there are several things to keep in mind: 1) "edifying readers" and "driving traffic to a particular website" more often than not, cannot be separated. Because through mentioning factual and objective information about anything (including a particular software product), you have to provide meaningful reference that a) proves what is written in the Wikipedia article, and b) allows those curious readers to investigate the subject matter further. Thus, in this sense driving traffic (which may or may not occur) is nonetheless just a side effect of the main point, which is to substantiate claims in the article by providing references and allow readers to investigate further; 2) While the search engine results are certainly not the best way to judge importance/popularity/relevance of anything, in some cases, there may be a few alternatives, as is in this case here, because a) most if not all books on biorhythms would not mention software, as they were written way before software became popular, and b) since the whole subject is rather very small and niche-oriented, you would be unlikely to find any detailed reviews of any biorhythm software.--George (talk) 11:24, 18 November 2009 (UTC)
You have a point, but the unlikely to find any detailed reviews of any biorhythm software still makes me worry that this is giving undue weight to this aspect of the topic. Would it be alright with you if we ask for a neutral, uninvolved third opinion at Wikipedia:Third opinion? I would word it as Question regarding inline external links at Talk:Biorhythm#Software. If you think that that wording is unlikely to bias whoever answers the call, go ahead and copy it over there or indicate here and I can do it. - 2/0 (cont.) 19:24, 18 November 2009 (UTC)
As for the undue weight - I would disagree, - how can we have a section on biorhythms application, nowadays the biggest part of which is software, - without mentioning a few prevalent software titles and referencing these titles with appropriate links? I would like to also point out, however, that this article is tagged with {{morefootnotes}}, and thus putting small inline references inside the text only improves the article, by addressing the issues outlined in this template. I have no objection to third opinion, however I think it may be best to let this discussion stay for sometime to collect more different opinions on the matter. --George (talk) 15:02, 19 November 2009 (UTC)

Oops, I removed the links again before I noticed this discussion. However, I would agree completely with 2over0, and I am convinced a third opinion would site with removing the links. George585 seems to have a conflict of interest. Haakon (talk) 11:52, 22 November 2009 (UTC)

What's the footnote for Biorhythms for Windows doing in that section then - which is quite outdated and a much-much less featured program then the two ones that were listed? Besides I emphasize once again the importance of mentioning specific software titles, as it constitutes a major area of biorhythm application. And no, I do not have a conflict of interest at all. I simply want a more through, relevant, and up to date presentation of information on biorhythm application. --George (talk) 12:10, 22 November 2009 (UTC)
I simply missed the other link, no ill faith was intended. I'm also not going to get into a revert war with you (note that you are now reverting two different people, which may be an indication that consensus disagrees with you), so at this point we need a third opinion. I have requested this here.
Can we take your statement that you have "no conflict of interest at all" as a declaration that you are not George Stivenson, owner of Haakon (talk) 12:40, 22 November 2009 (UTC)
Yes, I simply happen to be a user of some of their products that I like. I have no idea who the owner is. And in fact George585 is a nickname not a name! I also read on your userpage your attitude towards external links, however I think it is plain wrong to remove all relevant external links, even if some of them may link to commercial websites, because as was pointed out above by me, they serve a purpose of 1) edifying interested readers, 2) referencing factual information in an article, and 3) making encyclopedia contemporary (vs what you could read in a paper encyclopedia of 20 years ago). The reason I reverted your edit, was because I felt it was worng on your part to simply delete the links, without first discussing it here, so take no offense please. --George (talk) 13:31, 22 November 2009 (UTC)
Also note that I changed the format of the links and turned them into footnotes, as I guess that's what the debate was about, and footnotes are probably more appropriate in this case.--George (talk) 13:32, 22 November 2009 (UTC)
We're not debating whether they should be footnotes or links on some other formats; we're discussing whether or not Wikipedia should serve as a repository of external links if those links are perceived by some as "relevant". This involved interpreting or changing Wikipedia policy, which is why I requested a third opinion. Haakon (talk) 13:36, 22 November 2009 (UTC)
"We're not debating whether they should be footnotes or links on some other formats" - originally this was the exact issue that was debated! I would like to also add that simply mentioning the fact that there exist some software on biorhythms is not substantiated. In fact I say once again that this article was tagged that it needs more footnotes, and by mentioning specific software titles in the appropriate section with footnotes one is actually improving this article. --George (talk) 20:31, 22 November 2009 (UTC)
No, the exact issue was this edit, with an edit summary pointing out WP:NOTDIRECTORY -- Wikipedia is not a directory of links to products. The "footnotes" issue is not about footnotes as in the typographical practice, but about citing sources. A collection of links to products is not the same as citing sources. Haakon (talk) 20:46, 22 November 2009 (UTC)

Third opinion[edit]

I've undone George585's edits. Adding links into the prose like this is still a violation of WP:EL. It comes off a little like an advertisement, as if we're promoting those products over any others. This isn't a directory of links. — HelloAnnyong (say whaaat?!) 03:38, 23 November 2009 (UTC)

First of all, right now it looks as if you are promoting "Biorhythms for Windows" in the first paragraph of that section. How is that better than the products I listed? I therefore presume that that footnote should also be removed, as it is a link to product's homepage and not to an RS that cites the pilot using that program, which is what that sentence is about. Secondly, why did you remove my text as well? Removing links is one thing, and removing the text is another thing. It therefore creates an impression that there is only one good biorhythms program, which is simply not true. I therefore re-edited that section, with no links this time.--George (talk) 11:11, 23 November 2009 (UTC)
You seem hellbent on keeping the BinaryMark mention in the article. It was established in Wikipedia:Articles for deletion/Biorhythms Calculator, an AfD for an article you created, that the product is not notable. Haakon (talk) 11:23, 23 November 2009 (UTC)
First of all notability was established for the whole article, not for the mention in another article. Wikipedia's policy, makes a clear distinction between these two cases. Secondly, if you were careful enough, you would have noticed that I included company names for all three software products mentioned in that section, nothing special about BinaryMark at all. Company name serves to clarify the name of the software titles, so that those interested can find it, because names such as Universal Biorhythms or Biorhythms Calculator are no good in that respect. --George (talk) 22:25, 23 November 2009 (UTC)
I didn't comment on other sections of the article, but I would promote removal of promotional stuff as a whole. — HelloAnnyong (say whaaat?!) 15:01, 23 November 2009 (UTC)
I found and added a source for the use of biorhythms software by United Airlines, which looks like it was the book on which our text was originally based. As an independent source, it passes the minimum bar for mention, though it is not necessary. Given that Biorhythms for Windows is unlikely to have existed in the 1970s, I would be okay with rewording the specific program out. - 2/0 (cont.) 21:24, 23 November 2009 (UTC)
In my opinion it would be best to keep all three software titles in here, as otherwise this article is rapidly turning into a 1970s encyclopedia stub, which I guess is what some of the users here want many articles to look like. In any case, if you do remove the two titles I added, also remove Biorhythms for Windows, because nowhere is there a reference to a source that actually says this particluar product was used by a pilot as is mentioned in the section. --George (talk) 22:25, 23 November 2009 (UTC)
We have to stay true to the sources. If the source doesn't say Biorhythms for Windows was used, then it should not be included. Any text that's in here that's not attributable to a source is inherently original research. And adding a link to a product as a reference doesn't work for that either, by the way. — HelloAnnyong (say whaaat?!) 22:36, 23 November 2009 (UTC)
The problem as I see it is the following: 1. The main idea of that sentence is about a pilot using biorhythms in his daily life, not about the software. 2. Leaving only that software title in the whole article goes against the principle of objectivity, especially considering the fact that software (and websites) nowadays plays a major role in biorhythm application. In that regard, either Biorhythms for Windows should be removed from the text, because now it looks like advertising to me (at least the way it is phrased), and for the reasons listed above; or else this section be expanded and a few other software titles be mentioned.--George (talk) 15:16, 25 November 2009 (UTC)
And now it's gone. — HelloAnnyong (say whaaat?!) 15:32, 25 November 2009 (UTC)

I replaced all external links with a link to Dmoz. --Enric Naval (talk) 10:18, 25 September 2010 (UTC)

Fourth cycle?[edit]

The "calculations" section mentions a 38-day "intuitive" cycle, which is mentioned nowhere else in the article. Dare one say "citation needed"? (talk) 19:52, 7 May 2011 (UTC)

Odd phrasing?[edit]

Opening sentence:

"Biorhythm is an attempt to predict various aspects of a person's life through simple mathematical cycles."

Does this sound like correct English to everyone else? "Biorhythm is..." sounds strange to me. (talk) 00:29, 15 June 2011 (UTC)


It doesn't seem very plausible to me that a biological cycle of, say, 28 days could keep so exactly in sync throughout someone's life that one could pinpoint an exact day when the cycle peaked after forty years or whatever has elapsed. Is that what proponents believe? I'm wondering whether they think the cycle is automatically kept in sync by the daily rhythm, thus preventing it from drifting from an exact whole number of days. That would be much more plausible. I can't find out anything about this, and don't see it mentioned in the article, unless I missed it. I'd be interested to see these issues discussed in the article if anyone knows anything about it. (In case people get the wrong idea about my stance on this, yes, I know the whole theory is actually total nonsense, but that doesn't, and shouldn't, prevent us from documenting what supporters claim!) (talk) 01:03, 15 June 2011 (UTC)

Try Menstrual synchrony#Criticism. There is some discussion on how the cycles are difficult to measure and how they can be confused with random variations. --Enric Naval (talk) 16:20, 15 June 2011 (UTC)

Unsourced/dubiously sourced paragraph removed[edit]

In the workplace, railroads and airlines have experimented the most with biorhythms. A pilot describes the Japanese and American attitudes towards biorhythms.[1] He acknowledges, researching his pilot logbook, that his greatest errors of judgment occurred during critical days, but concludes that an awareness of one's critical days and paying extra attention is sufficient to ensure safety. A former United Airlines pilot confirmed that United Airlines used biorhythms until the mid-1990s, while the Nippon Express air freight still uses biorhythms.

The source given is a personal blog -- anecdotes are not great sources. It refers to another article for which it gives no reference. The blog does not back up the rest of claims about railways and airlines. — Preceding unsigned comment added by (talk) 09:39, 28 May 2012 (UTC)

Quote at end of lead[edit]

What is the quote ("The theory of biorhythms is a theory...") doing at the end of the lead. There are sources attached to it, but the text of the lead doesn't say who said it, or why it is notable - it's just sitting there randomly. It seems to be restating what the lead already says, and would suggest deleting it; if anyone thinks it's particularly important, it should be properly attributed, and probably put into a separate paragraph.Girth Summit (talk) 16:06, 3 June 2018 (UTC)
