{{cquote|Science is a liar sometimes!|||Mac, from ''Always Sunny'' <ref>[https://www.youtube.com/watch?v=Zgk8UdV7GQ0 "Science Is A Liar Sometimes"]</ref>}}
The phrase "'''science was wrong before'''" (or variations thereof, such as "'''science has been wrong in the past'''", "'''science is only human'''", "'''science keeps changing'''", or "'''science is not infallible'''") is a fallacious technique used in order to reject or disparage a current [[scientific consensus]], especially on topics such as [[evolution]] or [[global warming]]. It usually works like this:
{{cquote|'''Alice:''' A scientific consensus has built around [[theory]] X and it is supported by many lines of robust [[evidence]].<br/>
'''Bob:''' Ah, but [[science]] has been wrong before. Like bloodletting. So how can you be sure it's right this time?}}
The "science was wrong before" gambit exemplifies both the [[continuum fallacy]] and the [[nirvana fallacy]]. It is a sister-fallacy to "[[media was wrong before]]".

[[File:Scientific method.PNG|thumb|left|The [[scientific method]].]]
Usually (or at least often) "science was wrong before" is used to defend the existence of a ''[[Falsifiability|disproven]]'' phenomenon — [[alternative medicine]], [[perpetual motion]], [[crank]] [[Theory of Everything|theories of everything]], [[faster-than-light travel]]… the list is really endless for where this has been applied before. The usual examples of science being wrong (like the [[geocentric]] worldview that "science" used to hold) were theories that were in no way disprovable ''at the time'', much in the way that [[string theory]] cannot be readily disproved at ''this'' time. Many alternative medical practices, on the other hand, have been carefully shown to be utterly ineffective in one study after another — no additional information will suddenly contradict these results. When used like this, the "science was wrong before" trope is effectively like suggesting that our observations that [[gravity]] is an attractive force are ''wrong'', because one day in the future we ''might just'' see something go floating up instead of falling down, and [[Non sequitur|therefore]] [[homeopathy]] works.
So while it is true that several believed-to-be-true theories turned out to be wrong, that doesn't mean that theories that have already been proven wrong might suddenly turn out to be right, or that all theories with an overwhelming scientific consensus will necessarily turn out to be wrong.
===Missing the point===
[[File:240724175 10227181076779139 8654300658544882283 n.jpg|thumb|right|This is pretty easy to understand.<ref group=note>Totally unrelated: one word in this meme is misspelled. If you can find out in less than 10 seconds, you've shown that you actually paid attention in English class.</ref>]]
{{cquote|Scientific knowledge is often transitory: some (but not all) of what we find is made obsolete, or even falsified, by new findings. That is not a weakness but a strength, for our best understanding of phenomena will alter with changes in our way of thinking, our tools for looking at nature, and what we find in nature itself. Any "knowledge" incapable of being revised with advances in data and human thinking does not deserve the name of knowledge.|||[[Jerry Coyne]], ''Faith Versus Fact: Why Science and Religion are Incompatible'' (2015)}}
The logic behind this argument is [[fallacious]] in a number of ways. Primarily it misrepresents how science actually works by [[framing|forcing]] it into a [[false dichotomy|binary conception]] of "right" and "wrong". To describe outdated or discredited theories as "wrong" misses a major subtlety in science: discarded theories aren't really ''wrong'', they just fail to explain new evidence, and more often than not the new theory to come along is almost the same as the old one, but with some extensions, caveats, or alternatives.<ref group=note>Consider the mathematical constant [[pi]]. The value 3.14159 and the latest value calculated to millions of digits are both, in a sense, "wrong", but it would be absurd to say that mathematics doesn't know any more about pi than it did 2000 years ago. The currently calculated value of pi may be still ''absolutely'' "wrong", but it is many times ''more true'' than previous values. Similarly, though science may never know The Truth™, it certainly knows ''more'' now than it did hundreds of years ago.</ref> Often enough, these "new" theories are already in existence and just waiting in the wings, ready for new evidence to come along and differentiate them. This is well exemplified in [[Thomas Kuhn]]'s writing on scientific revolutions — a body of work that has been co-opted by many [[cranks]].
For example, take geocentrism. One of the strongest arguments against [[heliocentrism]] was the apparent lack of stellar [[parallax]] (or an apparent shift in the position of the [[star]]s from season to season). Because there was no evidence, Greek [[astronomer]]s assumed either that the stars were fixed in the sky (geocentrism), or that they were ''so far away'' that parallax was not noticeable. For almost 2000 years, there was no evidence for parallax, and it was not until the 1800s that parallax was proven to be correct and geocentrism soundly quashed.
Another example: the [[quantum theory]] doesn't explain gravity, but it does not invalidate the [[Schrödinger's cat|Schrödinger equation]] or the quantisation of [[energy]]; it merely says that the current formulation of the theory is incomplete and there are modifications to quantum theory already being formulated, ready for when the next big leap in observational evidence occurs.
That science can be "wrong" in this way is a ''feature'', not a bug, as one of the differences between science and [[pseudoscience]] is that science builds upon itself, whereas pseudoscience [[PRATT|rails on one claim and doesn't let up]], despite evidence to the contrary.<ref group=note>For instance, homeopaths will often cite an example of evidence disproving a previously-held scientific theory, and say that therefore people should believe in homeopathy – despite the fact that the scientific evidence overwhelmingly shows homeopathy to be ineffective. In other words, evidence against a mainstream theory is valid, but evidence against an unconventional one (such as homeopathy) [[Special pleading|is apparently not]]. (It's like pseudoscientists are more concerned about competing theories being correct than their own theories being wrong… probably because they're [[confirmation bias|entirely willing]] to resort to [[Escape hatch|dirty]] [[Moving the goalposts|tricks]] to [[handwave]] away any evidence that suggests that their theories are wrong.)</ref> These pseudoscientists present "science" as a monolithic entity with no differentiation between different sciences and the uncertainties and overlaps associated with each field. For example, an [[economic]] study of the [[minimum wage]] that uses the scientific method cannot be [[Reproducibility|replicated]] as easily as, say, a basic [[chemistry]] experiment that can be repeated in a lab — like finding the boiling point of a chemical. Thus, the economic study may not be "wrong", but has a lower degree of certainty attached to it than the chemistry experiment. Inability to make this distinction is often the result of the failure to think in a [[Bayesian]] fashion, in which the subtleties of errors are more accurately appreciated. Thus, the "science was wrong before" argument conflates different types of errors within science, confusing incompleteness of theories with being ''outright'' wrong. This, as [[Isaac Asimov]] called it in his essay ''The Relativity of Wrong'',<ref name=relativityofwrong /> is a form of being [[wronger than wrong]].
===Basic logical flaws===
But more than just being a complete misrepresentation of science, claiming that "science was wrong before" is flawed at even the basic logical level. First, this phrase can be considered a ''[[non sequitur]]'' or [[red herring]] because it usually has ''nothing'' to do with the subject at hand. For example, that {{wpl|phlogiston}} was wrong has no bearing on whether or not evolution is correct, and whether [[neutrino]]s may travel [[speed of light|faster than light]] has absolutely no relevance to homeopathy,<ref name="homeopathy">[http://gaia-health.com/gaia-blog/2011-09-23/subnuclear-particles-may-move-faster-than-light-who-says-homeopathy-cant-work/ Gaia-Health.com - Subnuclear Particles May Move Faster Than Light. Who Says Homeopathy Can’t Work?]</ref> as that is already governed by [[evidence for homeopathy|a certain evidence base]].
This is also a [[false dichotomy]]; someone using the argument is apparently suggesting that all science and [[rationalist]] thought must be perfectly correct the first time '''or''' their own selected ''[[woo]]-du-jour'' must be correct. Using a ''[[reductio ad absurdum]]'', the argument can apply to ''any and all'' forms of science and technology. (If [[hypotheses]] and theories which have been tested time and time again and been proven correct can be "wrong", what does that say about unproven, or even disproven, claims?) Therefore, there would be no way to test the validity of any claims, at all. But no one would say, "I'm not going to drive in a [[car]]! Science has been wrong before!" If "science has been wrong", and this disproves the effectiveness of earwax, doubly does it disprove the effectiveness of [[Ear candling|ear candles]].
For these reasons, "science was wrong before" is an objection that is [[not even wrong]], and tends to be used as a last-ditch [[escape hatch]] when the crank has run out of concrete objections or [[talking point]]s.
===The Bible was wrong before===
According to some Christians, [[But that was the Old Testament|the Old Testament was wrong before]] and needed to be "corrected" by the [[New Testament]]. Hence, if one accepts the premise of the "Science Was Wrong Before" argument, then one would have to conclude that The Bible cannot be trusted because it, too, was wrong before.
If you point this out to Christians who say "science was wrong before," they might respond by asserting that [[Special pleading|The Bible should not be held to the same standard as science]].

==Realism versus anti-realism in science==
While "science was wrong before" is most often used in service of science [[denialism]], though superficially similar, it should not be confused with a traditional argument found in the [[philosophy of science]] that is leveled against scientific realism, namely, the pessimistic meta-induction from past falsification of accepted scientific theories, which roughly goes like this: Since our best scientific theories have in the past been shown to be largely false, it is probable that our current accepted scientific theories are in large measure false. Therefore, we ought to be scientific anti-realists.<ref>Laudan, Larry "A Confutation of Convergent Realism", Philosophy of Science, Vol (48), No (1), (March 1981): 19-49.</ref> The realist vs. anti-realist debate concerns whether the theoretical entities (e.g. micro-physical particles, fields, etc.) postulated by our best scientific theories correspond to real entities or whether said entities, and the wider [[mathematical]] framework in which they are situated, are merely [[empirical]]ly adequate (i.e., computational tools via which we make successful predictions).<ref>For further detail, see the Stanford Encyclopedia of Philosophy entries for [http://plato.stanford.edu/entries/scientific-realism/ scientific realism], [http://plato.stanford.edu/entries/constructive-empiricism/ constructive empiricism] and [http://plato.stanford.edu/entries/scientific-underdetermination/ scientific underdetermination.]</ref>
Needless to say, this debate in the philosophy of science is much more complex and nuanced than shouting "Phlogiston! Hah, where is your science now?"

Similarly, though science may never know The Truth™, it certainly knows ''more'' now than it did hundreds of years ago.</ref> Often enough, these "new" theories are already in existence and just waiting in the wings, ready for new evidence to come along and differentiate them. This is well exemplified in [[Thomas Kuhn]]'s writing on scientific revolutions — a body of work that has been co-opted by many [[cranks]].
-
-For example, take geocentrism. One of the strongest arguments against [[heliocentrism]] was the apparent lack of stellar [[parallax]] (or an apparent shift in the position of the [[star]]s from season to season). Because there was no evidence, Greek [[astronomer]]s assumed either that the stars were fixed in the sky (geocentrism), or that they were ''so far away'' that parallax was not noticeable. For almost 2000 years, there was no evidence for parallax, and it was not until the 1800s that parallax was proven to be correct and geocentrism soundly quashed.
-
-Another example: the [[quantum theory]] doesn't explain gravity, but it does not invalidate the [[Schrödinger's cat|Schrödinger equation]] or the quantisation of [[energy]]; it merely says that the current formulation of the theory is incomplete and there are modifications to quantum theory already being formulated, ready for when the next big leap in observational evidence occurs.
-
-That science can be "wrong" in this way is a ''feature'', not a bug, as one of the differences between science and [[pseudoscience]] is that science builds upon itself, whereas pseudoscience [[PRATT|rails on one claim and doesn't let up]], despite evidence to the contrary.<ref group=note>For instance, homeopaths will often cite an example of evidence disproving a previously-held scientific theory, and say that therefore people should believe in homeopathy – despite the fact that the scientific evidence overwhelmingly shows homeopathy to be ineffective. In other words, evidence against a mainstream theory is valid, but evidence against an unconventional one (such as homeopathy) [[Special pleading|is apparently not]]. (It's like pseudoscientists are more concerned about competing theories being correct than their own theories being wrong… probably because they're [[confirmation bias|entirely willing]] to resort to [[Escape hatch|dirty]] [[Moving the goalposts|tricks]] to [[handwave]] away any evidence that suggests that their theories are wrong.)</ref> These pseudoscientists present "science" as a monolithic entity with no differentiation between different sciences and the uncertainties and overlaps associated with each field. For example, an [[economic]] study of the [[minimum wage]] that uses the scientific method cannot be [[Reproducibility|replicated]] as easily as, say, a basic [[chemistry]] experiment that can be repeated in a lab — like finding the boiling point of a chemical. Thus, the economic study may not be "wrong", but has a lower degree of certainty attached to it than the chemistry experiment. Inability to make this distinction is often the result of the failure to think in a [[Bayesian]] fashion, in which the subtleties of errors are more accurately appreciated. Thus, the "science was wrong before" argument conflates different types of errors within science, confusing incompleteness of theories with being ''outright'' wrong. This, as [[Isaac Asimov]] called it in his essay ''The Relativity of Wrong'',<ref name=relativityofwrong /> is a form of being [[wronger than wrong]].

-===Basic logical flaws===
-But more than just being a complete misrepresentation of science, claiming that "science was wrong before" is flawed at even the basic logical level. First, this phrase can be considered a ''[[non sequitur]]'' or [[red herring]] because it usually has ''nothing'' to do with the subject at hand. For example, that {{wpl|phlogiston}} was wrong has no bearing on whether or not evolution is correct, and whether [[neutrino]]s may travel [[speed of light|faster than light]] has absolutely no relevance to homeopathy,<ref name="homeopathy">[http://gaia-health.com/gaia-blog/2011-09-23/subnuclear-particles-may-move-faster-than-light-who-says-homeopathy-cant-work/ Gaia-Health.com - Subnuclear Particles May Move Faster Than Light. Who Says Homeopathy Can’t Work?]</ref> as that is already governed by [[evidence for homeopathy|a certain evidence base]].
-
-This is also a [[false dichotomy]]; someone using the argument is apparently suggesting that all science and [[rationalist]] thought must be perfectly correct the first time '''or''' their own selected ''[[woo]]-du-jour'' must be correct. Using a ''[[reductio ad absurdum]]'', the argument can apply to ''any and all'' forms of science and technology. (If [[hypotheses]] and theories which have been tested time and time again and been proven correct can be "wrong", what does that say about unproven, or even disproven, claims?) Therefore, there would be no way to test the validity of any claims, at all. But no one would say, "I'm not going to drive in a [[car]]! Science has been wrong before!" If "science has been wrong", and this disproves the effectiveness of earwax, doubly does it disprove the effectiveness of [[Ear candling|ear candles]].
-
-For these reasons, "science was wrong before" is an objection that is [[not even wrong]], and tends to be used as a last-ditch [[escape hatch]] when the crank has run out of concrete objections or [[talking point]]s.
-
-===The Bible was wrong before===
-According to some Christians, [[But that was the Old Testament|the Old Testament was wrong before]] and needed to be "corrected" by the [[New Testament]]. Hence, if one accepts the premise of the "Science Was Wrong Before" argument, then one would have to conclude that The Bible cannot be trusted because it, too, was wrong before.
-
-If you point this out to Christians who say "science was wrong before," they might respond by asserting that [[Special pleading|The Bible should not be held to the same standard as science]].
