“”It is not enough to wear the mantle of Galileo: that you be persecuted by an unkind establishment. You must also be right.
|—Robert L. Park|
The Galileo gambit (also Galileo fallacy; users of the fallacy are Galileo wannabees) is a logical fallacy that asserts that if your ideas provoke the establishment to vilify or threaten you, you must be right. It refers to Galileo Galilei's famous persecution at the hands of the Roman Catholic Church for his defence of heliocentrism in the face of the orthodox Biblical literalism of the day (though some alternative medicine proponents use Ignaz Semmelweis instead of Galileo). People use this argument repeatedly in response to serious criticisms that more often than not they just don't understand.
The structure of the argument is:
P1: A is X and Y
P2: B is X.
C1: B is Y.
- They made fun of Galileo, and he was right.
- They make fun of me, therefore I am right.

“”The chief problem with the Galileo gambit is the failure to understand the difference between a well-established scientific law and religious dogma.
In reality, taking up the mantle of Galileo requires not just that you are scorned by the establishment but also that you are correct — that is, that the evidence supports your position. There is no necessary link between being perceived as wrong and actually being correct; if people perceive you to be wrong, you usually are wrong. However, the selective reporting of cases where people who were persecuted or ostracized for beliefs and ideas that later turned out to be valid has instilled a confidence in woo promoters and pseudoscientists that is difficult to shake. They forget the part where they have to prove themselves right in order to be like Galileo.
The gambit takes many forms, but in most cases someone using it to promote their ideas will highlight their perceived persecution. This supposed persecution is blown out of all proportion until an observer almost has no choice but to accept their ideas practically as a sympathy vote. Such tactics are used in the "documentary" Expelled: No Intelligence Allowed, which focused on several academics who supposedly lost jobs because they promoted intelligent design as a valid hypothesis. The film portrayed this as a violation of academic freedom, and played the persecution card extensively. Among those capable of indulging this gambit, mere opposition to their crankery alone may be sufficient to induce the belief that they are being persecuted, and hence, were right all along.
An additional irony arises when we consider that if the maverick idea does manage to amass enough evidence to win over the majority, it will become the new consensus — at which point, by the fallacy's own reasoning, the idea must become wrong! After all, a new "Galileo" might assert that the Earth is indeed the universe's stationary center (some people actually do assert this). The astronomers who would disagree and point and laugh, by the fallacy's line of reasoning, are just the Catholic Church all over again, and they won't have the last laugh (though taking this a step further, neither will the new "Galileo"; an alternating series of laughs will terminate only when the human race disappears). This kind of madness may be consistent with certain flavors of postmodernism, but then again, so is everything else.
 The Galileo gambit in politics
In the West, this dodge was first employed on a large scale by early Christians, many of whom deliberately entered into confrontations with the Roman state and then obtained martyr status when they were executed, all according to plan. This allowed the Church to ask such questions as, "Would the Disciples die for a lie?"
 You get the most flak when you're over the target
"You get the most flak when you're over the target" is a pseudo-logical gambit, a favorite of Internet argument used as a substitute for rational rebuttal. Its intention, of course, is to prove that a hopelessly irrational woo proposition must be right because opponents are taking the trouble to criticize it. This fallacy is a major reason for real scientists' reluctance or refusal to debate creationists.
- Apparently, the converse does not apply. Woo-proponents have never been known to write "I must be wrong because I'm not being criticized", and will also use a lack of criticism as evidence for their position.
- You can also get plenty of flak if you're over the wrong target.
- Often anti-aircraft defences are set up in a ring around a target — so when you're directly over the target you would get less flak.

- ↑ One might argue that, since Nicolaus Copernicus was not persecuted for his theory (he died in 1543), it's just Galileo. (The difference here is Copernicus did not actively spread the idea, while Galileo did. Also, Galileo tended to provoke those holding the opposing viewpoint, and this often leads to one's ideas not getting the reception they deserve.)
