Relativity Measurable at Speed of Airplane

The effects of relativity were measured on a Boeing 747 going well below the speed of light. In addition, GPS literally depends on relativistic measurements to function. Even at 26,000 mph the effect is so large that it actually affects navigation calculations. — Preceding unsigned comment added by 99.48.42.65 (talk) 22:42, 20 September 2013 (UTC)

Eugenics?

Wouldn't eugenics be outdated? —Preceding unsigned comment added by Davidfarel (talkcontribs) 03:15, 12 May 2009 (UTC)

Not necessarily. While we know that the environment and experience can play a large or larger role than genetics themselves, there are still traits which can be helpful or harmful, and many of these are based almost exclusively in genetics. It's not inconceivable that eugenics will play a larger role in society in a few years or so... --Dagonius VI (talk) 01:39, 17 February 2010 (UTC)

Paleontology

There's PILES of room for Dinosaur theories (braciosaurus living underwater, pterosaurs being aquatic, and the second stegosaur brain come to mind), as well as the Aquatic Ape theory now that I think of it. Just a thought, Mr. Tachyon.

wait, there's no 2nd stegosaur brain?? :( --dan 04:12, 20 October 2006 (UTC)


Is Newtonian mechanics really "obsolete"?

Is Newtonian mechanics really "obsolete"? The overwhelming majority of working engineers and applied scientists still rely on it to solve problems, and you know what?...it still meets their needs, most of the time. It's true classical physics has been replaced by other sciences, but it's still used in the real world, so I find it hard to hear it called "obsolete". Revolver 03:02, 24 Feb 2004 (UTC)

Quite so. It fails under extreme conditions (or, more broadly, it succeeds under certain limited conditions that we happen to function in nearly 100% of the time), but it's commonly accepted in science and is not falsified within its own sphere. Only philosophically can it strictly be called obsolete. This make it an odd case, and might deserve a brief bit of text to this effect.
Obsolete is used in the sense of "outdated" and outdated scientifically, not obsolete in a practical useful sense. this is also stated in the article: "In some cases, the theory has been completely discarded. In other cases, the theory is still useful because it provides a description that is "good enough" for a particular situation, and is more easily used than the complete theory (often because the complete theory is too mathematically complex to be usable.)". However, perhaps a (but still useful) disclaimer on newtonian mechanics could be valid to avoid confusion (someone put one in but it was deleted). Pengo 12:09, 24 Feb 2004 (UTC)
BTW what exactly is the intent of this page? (I mean, besides flame bait, intentional or otherwise, for the holders of discredited or plain stupid theories.) Is it effectively a List page? Is it envisioned as having discursive text on obsolete theories? Dandrake 04:49, Feb 24, 2004 (UTC)
This is really a list page, and the "discursive text" for each theory is expected to be in their own articles. (original title of the page was "List of obsolete scientific theories").
Hopefully there will be minimal flame-age as theories that were never widely held in the first place are already to be excluded.
The point is to itemise theories which "were once commonly accepted but (for whatever reason) are no longer considered the most complete description of reality; or falsifiable theories which have been shown to be false." Hope this all clarifies things. Pengo 12:09, 24 Feb 2004 (UTC)

I think that one ought to distinguish between two kinds of obsolete theories:

  • Highly successful theories that turn out to be special cases of other theories, like classical physics
  • Weakly-supported speculations that become completely rejected, like plum-pudding atomic structure

Cases like phlogiston are in-between cases.

As to sources, I've found Asimov - The Relativity of Wrong. He described in it the difference between those two kinds of obsolescence. Lpetrich (talk) 15:51, 30 July 2012 (UTC)

No theory is obsolete

An item of scientific knowledge has a domain of applicability; for example, Newton's laws, in their classical form, are used everyday by engineers to design quite practical devices like cars. The scientific method teaches that a theory can be verifiable, or falsifiable, or self-contradictory, or ..., but the temporal tag obsolete is not quite in that spirit. 169.207.90.148 07:46, 24 Feb 2004 (UTC)

a theory that is falsifiable can be shown to be false. if it is shown to be false it is discarded, and therefore "obsolete". self-contradictory theories would fall into this category also. the term "obsolete" means in classical, scientific sense. not in a practical sense. Pengo 12:09, 24 Feb 2004 (UTC)

Neo-Lamarckism is said to be obsolete. Read Soma-to-germline feedback to see that there is still life in it and, the Weismann Barrier is also challenged.. GerardM 12:19, 24 Feb 2004 (UTC)

What I said, above. Dandrake 22:51, Feb 24, 2004 (UTC)
Ever heard about fundamentalism in science? Where is the open mind? And why call it flamebait? That is not my intention. GerardM 23:04, 24 Feb 2004 (UTC)

the term "obsolete" and page title

Seems to be some confusion about what is meant by "obsolete". Suggestions for a better term welcomed. Please see the blurb at the start of the article for what it's (meant to) mean. i'll start a brainstorm below: Pengo 12:09, 24 Feb 2004 (UTC)

Brainstorm for new titles:

  • scientifically obsolete theories (kinda odd)
  • no longer widely believed theories (too awkward)
  • falsified theories (too narrow and provocative)
  • add more
  • Superceded (Superceded scientific theories) - I started this article almost two years ago. I used the term "obsolete scientific theory" because I could think of no better term for it, and I put up the above request for a better name at the same time — "obsolete theory" does not come from the literature and I don't believe it to be in general usage. David Kernow recently changed one mention of obsoleted to superceded. Superceded is the word I'd been looking for: it is more neutral, clear, and broader than obsoleted. If no one objects I plan to change the title and headings to use the term "superceded" rather than "obsoleted". (Incomplete is a good suggestion, but Incomplete scientific theories would be a different article, as quantum mechanics may be incomplete, but has not been superceded, AFAIK). —Pengo 15:03, 12 December 2005 (UTC)

Weissmann barrier

By the way, to put the Weissmann barrier under obsolete theories, even with the qualifier that I added, is ludicrously POV. You might as well -- exacly as well -- put Evolution here, since the ID folks believe they've disproved it. It's exactly what happens when one creates a page like this: all the die-hards come out and assert that their ancient theories are not obsolete; what's obsolete is the stuff on which 99% of the science being performed in a field is based. Dandrake 02:27, Feb 27, 2004 (UTC)

most biology theories have exceptions. i actually put the weissmann barrier onto the page without thinking about it -- probably a mistake. so far there haven't been any real die hards trying to push their view point, and i dont think they will any time soon -- other than asking for a note to say their pet theory "isn't totally dead yet" -- and even then they hardly need to as that's being done for them. i think the real problem is how to classify theories that are still practical but otherwise disproven, or simply have minor exceptions (like weissmann's might) -- but i think that will sort itself out as the page grows.
perhaps a speculative page on what theories are on the way out would be more fun.. i mean.. controversial. Pengo 02:56, 27 Feb 2004 (UTC)
Sorry to keep nattering about this, but it gets more interesting. The Wiki article on the barrier leads one to a Web page that is not talking neo-Lamarckian nonsense doctrine, but raising what may be a valid problem relative to gene therapy. The relation of this to the validity of the "Weissmann barrier" is very dubious, though in a way it points out the sense in which the Wb is obsolete: it's an old dictum which, though essentially correct today, represents a 19th-century understanding. Guess I'll have to work with the Wb article. Dandrake 19:40, Feb 28, 2004 (UTC)

I removed the Weismann Barrier from the list of obsolete biology theories, because it doesn't seem to fit with things like spontaneous generation and Lamarckism. If anyone objects to this, feel free to add it back in. Factitious 03:25, Dec 1, 2004 (UTC)

Creationism

I fail to see how Creationism can be listed as an 'obsolete science', when "The Hollow Earth theory claims that the Earth is hollow, and its inside is possibly populated by a race of superbeings, humans or aliens, and possibly dinosaurs", a much less widely-held world view, is acceptable in the list of alternative, speculative and disputed theories.

Safest to leave Creationism in the list of alternative, speculative and disputed theories (where other religious or psuedo-religious theories are listed too), and remove it from the 'obsoleted' list. Tamias

Well, why is it still there? Any creationist (such as myself) could just as easily put evolution in the same place, even though the truth or falsehood of either cannot be proved. Since it is clearly POV, I have removed it. BASICwebmaster 05:04, 13 January 2006 (UTC)
But that's wrong. Evolution has been proven correct over and over again. --Dekker451 (talk) 13:38, 3 December 2010 (UTC)
Creationism shouldn't be here simply because it was never a scientific theory. --Tothebarricades 01:00, 25 February 2006 (UTC)
I agree - creationism was never a scientific theory. Bubba73 (talk), 01:10, 25 February 2006 (UTC)

Request for obsolete theories of electricity

There were several interesting but wrong (some slightly, some very) theories of electricity and magnetism. I have some references in some old college readers, but I thought someone else might be familiar with some examples (or able to find them on Google or elsewhere in the encyclopedia) before I get around to thinking about the question again (which might be several months). -- Beland 05:24, 30 Mar 2005 (UTC)

Obsolete or not?

At the moment Geocentric model is in the Category:Obsolete scientific theories while Bohr atom is not. Both are now commonly held to be ontologically deficient but both are still useful for computation and pedagogy. Surely we should be consistent but which way? Cutler 20:43, July 11, 2005 (UTC)

The Universe is Obsolete?

Are you kidding me? There is ZERO proof of a multiverse. It is entirely conjecture. Conjecture which I resonate with, but not scientific knowledge. Next are you going to tell me that the 4 dimensional world is obsoleted by the 11 dimensional world? I am removing this at once. (CHF 06:13, 17 November 2005 (UTC))

Basic spelling issue

The correct spelling, both in U.S. and U.K. English, is actually "superseded"--go ahead, look it up (I didn't believe it at first, either). But I'm a relative newcomer to Wikipedia and since the word is part of the title of this article, if I correct the spelling, it will probably mess up various links to this page. So I don't know what to do. Help? Thanks. DSatz 06:07, 27 December 2005 (UTC)

  • The OED does list supercede as an alternate, but it is only quoted in 19th century texts—supersede is clearly the preferred spelling. I'll move the page. (You can read about how to do this at meta:Help:Renaming (moving) a page; it's not too hard.) Brighterorange 16:30, 27 December 2005 (UTC)

theories, hypotheses and models

Some "theories" are more properly called hypotheses (such as about the aether) and models (such as of the atom). Should such distinctions not be made here? Harald88 21:05, 24 January 2006 (UTC)

I expect that in a section that talks about theories, the examples presented ought to be theories. Start a section on superseded hypothesis or models or whatever if you want to talk about those. Re-title this page to "Superseded Ideas in Science." Pooua (talk) 16:21, 7 July 2012 (UTC)

problem with change of definition

Someone changed the difinition of "no longer considered the most complete description of reality by mainstream [[science]" to the current one. However, a change of definition causes a changes of content. For example, the old definiton applies to ether theories, but the new one doesn't - the last ether-based (nowadays called "field") theories by Lorentz and Einstein are as accurate as can get. I think that superseded should apply to all scientific theories that are not commonly used anymore and not only to "less accurate" theories. Note also that a (metaphysical)concept such as aether (or spacetime) is not a scientific theory! Harald88 18:25, 9 May 2006 (UTC)

geocentric universe

right in the intro, it says that "Some theories which were only supported under specific political authorities may be included (like Lysenkoism) or may not be included (like the model of a geocentric universe)", but then down the list i see "Ptolemaic system/Geocentric universe". is ptolemaic/geocentric different from plain geocentric, or is that a mistake? --dan 04:19, 20 October 2006 (UTC)

And He formed the earth ...

I think this has the basis of a good article but lacks the things discussed at featured list nomination above. I included expanding earth a while ago but am interested to see how this page can illustrate the formation of paradigms in science. Don't think it should be adopted by physics project only but best examples would be those. Fred.e 17:11, 16 December 2006 (UTC)

Continental Drift?

As I understood it, the theory of contiental drift simply says that the continents move about a bit. It's not been replaced by plate tectonics, but plate tectonics is simply the mechanism by which continental drift occurs. Wegener's original vague theories for the mechanism have been discredited in favour of plate tectonics, not continental drift itself. Or am I completely wrong? It has been known. --MockTurtle 18:41, 9 August 2007 (UTC)

Formatting error in the "Approximate Theories" section?

In this section, the following are two bulleted points: "Atomic theory - Atoms are no longer thought to be indivisible, but are now seen to be composites" and "Nuclei disintegrate at high energy". It seems to me that the second point was meant to be an explaination of the first point. 134.173.74.161 (talk) 08:09, 17 December 2007 (UTC)

Progression of the atomic theory

I was just reading some fun stuff in Asimov's Understanding Physics about how, historically, a lot was figured out about nuclear isotopes before the discovery of the neutron, and that all the theoreticians in this time were working with a ridiculous model (ridiculous only in hindsight, since the strong nuclear force hadn't been discovered yet) of extra electrons embedded among the protons in the atomic nucleus to cancel out the necessary amounts of charge. This model was short-lived, certainly, but some important contributions to science were made during its short lifetime. Ought it not have a name? arkuat (talk) 10:14, 7 June 2008 (UTC)

Scientific theories? I don't think so.

Geocentric universe? Flat Earth theory? Astrology? The first paragraph calls this a list of scientific theories, but this seems like a list of historical conjectures. "Theory" in everyday language is not nearly the same thing as a scientific theory.

Are Superceded/Obsolete Scientific Theories Really Pseudoscience or Something Else?

Based on arbitration and clarification on same, the Pseudoscience category, which has been applied to this page, and the Obsolete Scientific Theories category, requires a citation from a reliable general source like the Encyclopedia Britannica describing the subject as pseudoscience, or a reliable academic source such as an Academy of Science which considers the subject to be pseudoscience, so as to sustain the category's placement. Can you point out some reliable source that will settle the matter? If not, we'll need to remove the Pseudoscience category tag from this page and its corresponding category. Thank you.-- self-ref (nagasiva yronwode) (talk) 22:34, 13 October 2008 (UTC)

This is getting tedious...would it pain you to finish a relevant & related conversation before jumping into the talk page of a highly related subject to apply your template message? Maybe even link to a relevant discussion?
Regarding this page...did you read the list of topics? There are clearly topics on this page that should be (and are) categorized as pseudoscience. That makes Category:Pseudoscience a generally applicable category. As with the categorization of a category (this discussion), the categorization of a list is common sensically more utilitarian than a single article--and the linkage is, to me, self-evident. As with obsolete theories, any adherents to a superseded may display the hallmarks of pseudoscience. — Scientizzle 00:28, 14 October 2008 (UTC)

Unreferenced tag

This article will need references if it is to ever reach GA status. It frankly amazes me that it was ever assessed as a B class article in its present unreferenced state. While it appears well written it is not verifiable without references. I don't consider that to be a major problem in the portion which is just a list of wikilinks, but the introduction at least should be referenced.Trilobitealive (talk) 13:02, 9 May 2010 (UTC) (See Wikipedia:Featured list candidates/Superseded scientific theory for other opinion about its lack of references.) Trilobitealive (talk) 13:04, 9 May 2010 (UTC)

Uh, what?

This article reads as if it were written word for word by creationist lobbyists or someone else attempting to discredit the scientific process. It refers to conjectures and widespread beliefs as if they were scientific theories. For example, it refers to miasmatic theory as if it were a scientific theory, despite the fact that miasmatic theory came about in Ancient Greece, millenia before the scientific method was even established! This disinformation is multiplied by the fact that the definition of a scientific theory is stated in the opening of the article, and then the term, "theory," is used for its common use repetitively after that. If this were the only error it could be fixed, however it appears as though the entire article has been written for the sole purpose of attempting to show the previous errors in science, and then expanding that list to include the previous errors of human thought, and then make no distinctions between the two. To actually fix this article would take much more effort than I have to spare at the moment, and is properly more editing than one person should do to an article, but there is so much disinformation and misleading information in this article that it is somewhat unbelievable.

This afternoon I'm going to create a new article for previously widely held beliefs in humanity's history, and then properly sort the items into the two. As it stands, this article is just creationist propaganda.

Additionally, there is no need for this article to be under the pseudoscience tag. A superceded scientific theory is not pseudoscience, it is obsoleted science. That is a grave distinction. Also, an idea that was created before the scientific theory was is also not pseudoscience, but just a myth.—Preceding unsigned comment added by 124.212.161.229 (talk) 04:00, 3 December 2010 (UTC)

Misapplies specific disproof into too many applications.

Geological catastrophism is only partially obsolete, since some catastrophic events have undeniably happened. Of course much of geology is gradual, but not all.

Lamarckian inheritance is actually partially vindicated by epigenetics.

Telogeny is in a (very) small part vindicated by chimera research, that fetus cells can stay in a mother`s body, although of course only if it was a pregnancy. By the way, the Nazi Nurenberger laws from 1935 did not mention previous mates of the mother at all, only parents and grandparents.

Cultural "universals" (more properly called "globals") do not prove that it is innate. Similar behaviors can be instrumentally invented because of similar problems.

The definition of "purely behaviorist theory of language acquisition" is unclear. Poverty of the genome debunks nativist reductionism at least as much as poverty of the stimulus debunks behaviorist reductionism. Emergent theories are undeniably necessary. Classical Skinnerian behaviorism is obsolete. But arguments on the lines of "language is very complicated yet children learn it easily" are invariably symptoms of the "general intelligence is reducable to mental age" fallacy. Human brains differ in general ability from animal brains not only in learning ability but also in neurological precision, since brainpower improves the precision of conceptualization. All differences between human symbolic language aquisition and animal associative learning can be explained by the difference in conceptual precision, as shown by the fact that human language differs from animal communication primarily by having specific words for specific concepts instead of just signals for whole contexts. As shown by studies of science-like exploration of the world performed by human children, the ability to ask questions can also be explained by conceptual precision.

Please make the article more precise and stop doing false generalizations!217.28.207.226 (talk) 11:53, 6 December 2011 (UTC)Martin J Sallberg

The bullet-point form of this article doesn't lend itself to explaining the subtleties you've outlined (not to say we shouldn't try), though sometimes there's already hints of it. For example, Lamarckism does mention epigenetics as one of the theories it's been obsoleted by. If you'd like to contribute to the article, adding a discussion of the topics you mention would be most welcome. —Pengo 23:16, 8 December 2011 (UTC)
The article doesn't state that all are completely discarded, the lede says "... in these cases, the older theory is often still useful because it provides a description that is "good enough" for many purpose". This is the case for some of the obselete theories. IRWolfie- (talk) 16:38, 20 December 2011 (UTC)

Dates might be helpful

The reader would have a much better idea of context if some dates were judiciously used. As it might be difficult to date theories or their obsolescence, it would be possible to include birth-death dates of specific persons. Any thoughts? YBG (talk) 13:55, 25 January 2012 (UTC)

Removed 'Lumniferous Aether' and 'Classical physics'

While I agree that there are obsolete and superseded scientific theories, you cannot simply dismiss classical physics as superseded altogehter! That would be deafening arrogance towards the very history of science. Besides, many different kinds of lumniferous aether have been proposed, and until quantum physics comes up with an even remotely sensible explanation for the mechanisms responsible for natural law, and as long as mainstream science remains where we are now, in the dark about what 70% of the universe is even made of, it makes no sense to conclusively discard such theories, aspects of which may still bear importance for future research.

I understand that there is a reasonable interest in keeping the hordes of pseudo-scientist-tesla-free-energy-amateurs at bay with their conspiracy theories etc.; but we have an obligation to be humble towards truth itself, since history has demonstrated how false our beliefs about a certain principle or concept often are.

"Steady State Theory, a model developed by Hermann Bondi, Thomas Gold, and Fred Hoyle whereby the expanding universe was in a steady state, and had no beginning. It was a competitor of the Big Bang model until evidence supporting the Big Bang and falsifying the steady state was found." Again, evidence thought to support the Big Bang theory does _not_ prove it true, and thus does _not_ disprove or prove any other theory regarding the state of the universe (steady, expanding, contracting, etc.). — Preceding unsigned comment added by 178.190.24.26 (talk) 10:55, 30 July 2012 (UTC)


JJ — Preceding unsigned comment added by 178.190.24.26 (talk) 08:36, 30 July 2012 (UTC)

Classical physics while useful has been superseded: being superseded doesn't mean that something isn't useful. I don't think anyone is arguing that the Big Bang theory has been proved to be true; but that the evidence has invalidated steady state theory. There is a difference. That is what science does; it puts hypotheses to the test and invalidates them if they fail the test. From a wikipedia point of view we can add theories that are regarded as being superseded to the list as long as they are regarded as such by the scientific mainstream. If you are uncertain about any specific entry, mark them with the citation needed template, and someone will get the citation. IRWolfie- (talk) 11:03, 30 July 2012 (UTC)

Confuses the concept of a scientific theory

Many of the "theories" included in this article are simply historical ideas and do not fit the definition of a modern scientific theory. This article simply adds to the rampant confusion between the concept of the scientific theory and the more common use of the word "theory".

Here is a quotation from the American Association for the Advancement of Science:

""A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported theories are not "guesses" but reliable accounts of the real world. The theory of biological evolution is more than "just a theory." It is as factual an explanation of the universe as the atomic theory of matter or the germ theory of disease. Our understanding of gravity is still a work in progress. But the phenomenon of gravity, like evolution, is an accepted fact.""

I believe that this definition excludes many of the "theories" listed in this article. Of course each topic could have its own debate as to its eligibility as a theory, I don't think that Wikipedia is the place. Just like Wikipedia is not the place to debate the legitimacy of biological taxonomic classifications. I suggest that this article be renamed to "Superseded scientific ideas". And the word "theory" should be avoided in most cases to remove the confusion. — Preceding unsigned comment added by Xyrtex (talkcontribs) 21:56, 4 November 2014 (UTC)

  • I agree, most of these "theories" are hypotheses, a very different beast. --Randykitty (talk) 14:54, 14 December 2014 (UTC)

Telegony

'Telegony – the theory that an offspring can inherit characteristics from a previous mate of its mother's as well as its actual parents, often associated with racism'.

Should this be counted as superseded or obsolete? While it may not be true in humans, the page for telegony states that 'a group from The University of New South Wales[14] has showed telegony to be a true and valid phenomenon for the first time in a species of fly'.

Improved lead

Presuming that the current deletion discussion results in a 'keep' decision, I think the best way forward is to first improve the lead, and then, if necessary, move the article to an appropriate title.

Here is how I think the lead should be organized:

  1. Define the topic
  2. Clarify the universe of ideas topics to be considered
  3. Clarify what it means to be superseded, ie, rejected as false or replaced by something more accurate.

Next, my stab at the first sentence:

  • This is a list of ideas about the natural world that were once widely accepted by natural scientists (or their predecessors, natural philosophers) which have now been superseded by more accurate ideas.

Comments? YBG (talk) 03:52, 23 December 2014 (UTC)

Here is a revised idea for the first sentence:

  • This is a list of ideas about the natural world that were once widely accepted by natural scientists (or their predecessors, natural philosophers) which as a result of experiments are now widely understood to be inadequate, incomplete or false and so superseded by more accurate ideas.

It is disappointing that in the two years since my suggestion above there have been no comments. It is my belief that until a better lede is constructed, we will continue to have periodic discussions as the one that prompted my 2014 comment and the one currently going on.

Requested move 29 December 2014

The following is a closed discussion of a requested move. Please do not modify it. Subsequent comments should be made in a new section on the talk page. Editors desiring to contest the closing decision should consider a move review. No further edits should be made to this section.

The result of the move request was: No consensus to move. There is a general sense that some move may be needed, but no agreement that the proposed title is the best one. It's therefore best to follow the suggestions made in comments below to come up with the best title before starting a new RM. (non-admin closure)  — Amakuru (talk) 18:36, 19 January 2015 (UTC)



Superseded scientific theoriesSuperseded scientific ideas – The article is more about ideas than theories, at least to the extent that testability is important in theories. See the recent discussion at Wikipedia:Articles for deletion/Superseded scientific theories. This new title may help frame the issues in the above /* Improved lead */ section, and thos ethat led to the Afd in the first place. This new title seems to meet the requirements of being recognizable, natural, concise, and relatively precise, given the subject matter. The term "superseded scientific ideas" has some usage, see quotes here. Bejnar (talk) 10:06, 29 December 2014 (UTC)

  • Oppose the move as proposed. I'm sympathetic to the nominator's issues with the present title, but what's a "scientific idea"? Is it distinct from a mere "idea"? If so, how? Are there ideas that aren't scientific? Which of those are in scope, and which aren't? You might think that the answers to these questions are obvious (they are), but a short page title has no room for a discussion of those answers. The word "theory", with a loaded scientific meaning, at least acts as a proxy definition of the scope. 209.211.131.181 (talk) 15:18, 29 December 2014 (UTC)
  • Comment - This probably merits a discussion thread on possible names before proposing the move. --— Rhododendrites talk \\ 15:43, 29 December 2014 (UTC)
  • Comment I am not sure that Superseded scientific ideas is the right title. Perhaps "Superseded Ideas in Science and Natural Philosophy". In my opinion a scientific idea would be an idea that arose from the application of the scientific method. Many of the entries in this article came from an era that predates the scientific method or a time when the application of the scientific method was a bit fuzzy. It seems to me that this article is meant to document changes in human perceptions toward the natural world. I think that we need a title that is inclusive to the early ideas of natural philosophy, but exclusive of things like theology ect., or we could keep the current title and start deleting all the entries that shouldn't be there. In the spirit of good faith, I will wait before making deletions. Although, I do think that a few like "Island of California" will need to be removed regardless of a new title.Xyrtex (talk) 18:22, 29 December 2014 (UTC)
Xyrtex I think that you make a valid idea with Superseded ideas in science and natural philosophy. While not wanting to supersede this I would also like to suggest: Superseded ideas, concepts and theories in science and natural philosophy. GregKaye 06:58, 30 December 2014 (UTC)
  • Oppose move. Nothing wrong with current title. Theory is a broad concept and the article seems to cover that in a sufficiently balanced way. - DVdm (talk) 18:57, 29 December 2014 (UTC)
  • I'm confused. What concept of theory are you referring to? Numerous references are available that discuss the definition of a scientific theory and the difference from the common use of the word theory. Do you have a reference for the broad concept that you speak of? Are you suggesting that all (or even a majority )of the entries in this article are scientific theories?Xyrtex (talk) 19:52, 29 December 2014 (UTC)
Referring to the concept(s) as outlined in our article Theory. - DVdm (talk) 19:58, 29 December 2014 (UTC)
The article clearly is referring to scientific theory.Xyrtex (talk) 20:09, 29 December 2014 (UTC)
So is this one, at least in a sufficient way to keep the title, i.m.o. - DVdm (talk) 20:53, 29 December 2014 (UTC)
Once again I am confused. Are you saying that theory is synonymous with scientific theory? I think that the point here is that most of the content of this article will need to be removed as it stands under the title of scientific theories. Do you feel that all the entries that are not scientific theories should be deleted, or do you feel that the term scientific theory is, for the most part, properly used here?Xyrtex (talk) 21:22, 29 December 2014 (UTC)
But many of the ideas in the article are not scientific in the sense of "scientific theory". --Bejnar (talk) 21:27, 29 December 2014 (UTC)
  • Comment As I mentioned above, I think the best way forward is to re-write the lead paragraph before deciding what is the best title. YBG (talk) 19:41, 30 December 2014 (UTC)
  • Support in theory, but share the concerns expressed above. Regardless, the present title is clearly misleading.  — SMcCandlish ¢ ≽ʌⱷ҅ʌ≼  10:47, 15 January 2015 (UTC)

The above discussion is preserved as an archive of a requested move. Please do not modify it. Subsequent comments should be made in a new section on this talk page or in a move review. No further edits should be made to this section.

Consensus?

The first sentence of this article states that superceded scientific theories were once accepted by the "mainstream scientific consensus." Consensus doesn't seem to be an essentieal part of superceded scientific theory; in what Thomas Kuhn once called the pre-paradigm stage, there were several competing scientific thories, most (or all) of which are now consideed to have been inadequate. Taking a couple of examples from the list: preformationism was one of a number of rival theories of the origin of biological organisms; the emission theory of vision coexisted for a long time with intromission theories, until finally superceded by Alhacen's theory intromission theory which creatively drew elements from the mathematics of the emission theory.

At the least, the requirement for consensus should be removed from the lead. --SteveMcCluskey (talk) 02:13, 20 March 2016 (UTC)


This is a critical discussion, because the value of contemporary "science" is often attacked by non-scientists with no understanding of the scientific method. Their argument is typically, "Many ridiculous scientific theories were accepted in the past. Therefore, science is untrustworthy. We should not trust scientific theories of today." That argument is based on a false premise, which must be corrected in this article.

Here is the false premise: the discredited ideas listed in the article are scientific. They are not.

The discredited ideas listed in the article, e.g. "miasma theory of disease," are properly called "philosophies," "beliefs," "convictions," "deductions," "speculations," "conjectures," etc. All of those descriptions fit the colloquial, not the scientific, definition of the word "theory."

For example, the article itself states there was "no experimental support" for the "miasma theory." That is an oxymoron. A scientific theory MUST have robust empirical support; if not, it is not a scientific theory.

The confusion arises among the non-scientific public because the Scientific Method has proven so successful in explaining the natural world, that all methods which purport to explain the natural world are often today (mistakenly) called "scientific." The natural world is the domain of many explanatory methodologies (e.g. religion, folklore, mythology, voodoo). Only one methodology is properly called "scientific": the one grounded in the Scientific Method.

Hence, it's as misleading to call "miasma theory" a superseded scientific theory, as it is to call "voodoo" a superseded scientific theory.

Some of the discredited ideas listed in this article predate the first known description of what we now call the Scientific Method by thousands of years. What we now call the Scientific Method was first described by Francis Bacon in 1620, who called it "Novum Organum Scientiarum," (New Instrument of Knowledge). It wasn’t until the 19th Century that Bacon’s “Instrument of Knowledge,” due to its demonstrated success, acquired the name “Science” (from the Latin “scientia,” from “sciens,” which means having knowledge, from the present participle of “scire,” meaning to know).

In the context of the Scientific Method, “theory” has a related, but different meaning than in colloquial English. **Everything** in science is a theory. For example, “Gravitation” is a theory (https://en.wikipedia.org/wiki/Gravity#Newton.27s_theory_of_gravitation). Scientific theories are never “proved,” the way a deduction can be logically proved. The Scientific Method does not prove theories. It empirically disproves false ones. So, scientific theories are inductively substantiated on a continuum of confidence from “weak” to “strong". Indeed, the whole process of “doing science” is one of continuously trying to empirically disprove current theories, discarding them, creating new theories, then attempting to disprove those. In the process, confidence in the current theory grows. Thus, “the theory of gravity” *could* be wrong. By analogy, one *could* win a lottery ticket. The question is, where do you want to place your bet? Though not perfect, scientists are rigorously trained to place good bets on their explanation of the natural world.

Please see description of The Scientific Method (https://en.wikipedia.org/wiki/Scientific_method). Any idea predating the invention of the Scientific Method is, by definition, not scientific. Nor is any idea which originates in a non-scientific methodology, scientific. What makes something “scientific” isn’t the domain (the natural world); it is the methodology.

Thus a better title for this article is, “Pre-Scientific Explanations of the Natural World,” or perhaps, “Pre-Science.” Fredric5765 (talk) 03:20, 23 March 2016 (UTC)

If the proposer wants to advance this proposal for a change in the article's title, it should be done by a formal request to move the article. I should point out it will be a controversial proposal (I, for one, would oppose it).
The proposal misses the fact that this is a history of science article and historians of science include the sciences of different times and cultures among their definition of science. I could quote many definitions of science proposed by historians of science but one fairly complete and generally accepted one is that of David Pingree: "Science is a systematic explanation of perceived or imaginary phenomena, or else is based on such an explanation. Mathematics finds a place in science only as one of the symbolical languages in which scientific explanations may be expressed. This definition deliberately fails to distinguish between true and false science, for explanations of phenomena are never complete and can never be proved to be 'true'".[1]
Such a broad definition encompasses all attempts to come to a systematic explanation of natural phenomena -- everything from Aristotle's Physics to Stephen Hawking's -- within the framework of scientific theory. Hence the title of the article is well-founded. --SteveMcCluskey (talk) 20:01, 23 March 2016 (UTC)

Thank you for your thoughtful reply. I will either make the formal request to move (your suggestion), or propose edits to this article to differentiate the "Pre-Scientific Era" from the "Post-Scientific Era" in the "History of Science."

Definition of prescientific

   :  of, relating to, or having the characteristics of a period before the rise of modern science or a state prior to the application of the scientific method

http://www.merriam-webster.com/dictionary/prescientific

Re: the Pingree quote (above), most any modern scientist would likely agree. His (valid) point is that mathematics is merely a useful scientific tool, as a telescope is a useful scientific tool. Neither the use of mathematics nor the use of a telescope makes any theory, about anything, more credible. Mathematical proofs can be epistemologically certain within the domain of mathematics, period. Scientific theories can never be epistemologically certain, even if they rely upon mathematics. But they are still very different from non-scientific theories: scientific theories become strengthened by empirical evidence, else they are discarded.

The first sentence of this article is, "A superseded, or obsolete, scientific theory is a scientific theory that was once widely accepted within the mainstream scientific community..." None of the examples cited in this article meet that criterion. The "mainstream scientific community" (i.e. practitioners of the Scientific Method) did not even exist until the invention of the Scientific Method. "The concept of scientific communities emerged in the second half of the 19th century, not before, because it was in this century that the language of modern science emerged, the professionalization of science occurred, specialized institutions were created, and the specialization of scientific disciplines and fields occurred." https://en.wikipedia.org/wiki/Scientific_community

Re: the McCluskey quote (above), it's true that "such a broad definition encompasses all attempts to come to a systematic explanation of natural phenomena." But based on the comments here, that seems quite misleading for everyone except, perhaps, historians of science. It's a problem because skeptics of modern science (post-scientific method) argue that no result of modern science should be trusted, because there exist examples of bad results achieved by practitioners in the same domain, using antiquated methods, and results from modern methods are not perfect (mathematically provable). That's like arguing that modern indoor plumbing should not be trusted, because people once got cholera from water wells, and people sometimes still get cholera from water.

Most people reading this article are neither scientists nor historians. Granting that historians and scientists define "science" differently, at the very least, the different meanings of the word should be provided here:

"In the context of modern historical studies, 'science' encompasses all explanations of the natural world, such as the methods used by ancient Greek philosophers. In all other contexts, 'science' means the application of the Scientific Method to the study of the natural world, a practice which began in the late 18th Century."

Also, see e.g. "History of Medicine" https://en.wikipedia.org/wiki/History_of_medicine#19th_century:_Rise_of_modern_medicine

"During the Age of Enlightenment, the 18th-century, science was held in high esteem and physicians upgraded their social status by becoming more scientific." "19th century: Rise of modern medicine"

Another idea is, if this is an article about "History of Science," then it should be organized chronologically and divided into "Pre-Modern" and "Modern" era. "Modern" means after the invention of the Scientific Method.

Made obsolete by Copernicus

The article says Geocentric theory and the ptolemaic system were made obselete by Copernicus but at his time most scientists rejected heliocentricism and it was later discoveries that led to geocentricism being abandoned.Ilikerabbits! (talk) 15:21, 18 June 2017 (UTC)

Citations needed

Since 2008 this article has had a template flagging that citations are needed. Very few have been provided.

The Manual of Style specifies that "Stand-alone lists are subject to Wikipedia's content policies and guidelines for articles, including verifiability and citing sources. This means statements should be sourced where they appear, and they must provide inline citations if they contain any of the four kinds of material absolutely required to have citations." The four kinds of material mentioned here include "Any statement that you believe is likely to be challenged."

As it stands, most of this article is unverified and open to challenge and has been so for almost a decade, and is therefore liable to deletion. Would editors please provide citations for each item on the list. --SteveMcCluskey (talk) 21:39, 21 February 2018 (UTC)

I just came across a further section of the MOS, which spells out citation policies for lists more clearly: "all individual items on the list must follow Wikipedia's content policies: the core content policies of Verifiability (through good sources in the item's one or more references), No original research, and Neutral point of view, plus the other content policies as well." --SteveMcCluskey (talk) 17:22, 22 February 2018 (UTC)
