The No True Scotsman (NTS) fallacy is a logical fallacy that occurs when:
- during argument, after their favored group has been criticized, someone re-defines the group in order to deflect uncomfortable counter-examples and thus makes the group entirely praiseworthy; or
- before argument, someone preemptively defines the group such that the group definitionally must be entirely praiseworthy, but said definition was created arbitrarily for this defensive purpose, rather than based on actual qualities of the group.
NTS is generally used in order to make the argument that no element worthy of criticism can ever be held against some group.
Despite all of these remarkable qualities, the NTS fallacy is a vital tool in the promotion of denialism.
The term was coined by Antony Flew, who gave an example of a Scotsman who sees a newspaper article about a series of sex crimes taking place in Brighton, and responds that "no Scotsman would do such a thing."
When later confronted with evidence of another Scotsman doing even worse acts, his response is that "no true Scotsman would do such a thing," thus disavowing membership in the group "Scotsman" to the criminal on the basis that the commission of the crime is evidence for not being a Scotsman.
However, this reasoning is fallacious, as there exists no premise in the definition of "Scotsman" which makes such acts impossible (or even unlikely).
“”Angus declares that Scotsmen do not put sugar on their porridge[.] [...] Lachlan points out that he is a Scotsman and puts sugar on his porridge. Furious, like a true Scot, Angus yells that no true Scotsman sugars his porridge.
P1: All X are Y.
P2: Clearly, not all X are Y.
C1: All true X are Y.
In practice, application of the NTS fallacy is far more subtle than this, but the line of thinking always boils down to a denialistic attitude towards counterexamples.
 Retroactive No True Scotsman
When used in the past tense, NTS can also be used to retroactively disqualify group membership based on future wrongdoing. In this scenario, the axiom becomes "having done something bad just proves how you never really were a member of this group in the first place", a statement as comfortably shallow (and unapplicable to reality) as the claim that your sports team is the best, because it is by definition "the team that wins the game".
NTS is a fuzzily-defined fallacy, because the nature of "groups" themselves is fuzzy. It's hard to definitively say where one group ends and another begins (think Catholics versus Protestants: how many Catholic traditions does one have to follow to be Catholic?). Thus, there are some notable exceptions to NTS.
 Well-defined Scotsman
Noteworthy is that the fallacy does not occur if there is a clear and well understood definition of what membership in a group requires, and it is that definition which is broken (e.g., "no honest man would lie" or "no theist can be an atheist" and so on). Thus, the NTS fallacy only occurs if the group is later redefined for no valid reason.
NTS places no restrictions on whether a definition is sensible or not. NTS only concerns if a definition is applied consistently or not.
 Constantly-shrinking Scotland
The fallacy does not occur in defining a group narrowly to begin with (unless said definition skips the intermediate steps shown here), but rather in continously narrowing the definition of said group by specifically excluding evidence that contradicts an initially broad (and generally flattering) definition. For example, a definition that began "Christians claim Jesus Christ as their savior" might become "Christians claim Jesus Christ as their savior and follow his morals" and "Christians claim Jesus Christ as their savior and follow his morals and love homosexuals" and so on. Thus, the NTS fallacy, taken to its logical conclusion, would suggest that the "best" member of a group represents it.
Ann: "Dolphins don't swim in the water."
Bob: "*points out a photo of dolphins in the water*"
Ann: "Those aren't true dolphins -- no true dolphin swims in the water."
 In religion
“”No man can ever be opposed to Christianity who knows what it really is.
|—Henry Drummond, the Scopes Trial|
With respect to religion, the fallacy is well used, often even overused. Religious apologists will repeatedly try to use NTS to distance themselves from more extreme or fundamentalist groups (and vice versa), but this does not prevent such extremists actually being religious — they themselves would certainly argue otherwise. Moderate Muslim leaders, for example, are well known for declaring Islamic extremists as "not true Muslims" as Islam is a "Religion of Peace."
Similarly, moderate Christians, such as those in Europe, are sometimes aghast when viewing their fundamentalist counterparts in the US, immediately declaring them "not true Christians," even though they believe in the same God and get their belief system from the same book. Many of these statements stating that the extremists are not true believers are often used as a reaction against Guilt by Association. The NTS fallacy likewise occurs when believers attribute any and all good fortune to divine intervention on their behalf, yet insist that the same can never be true when things go awry.
The NTS fallacy can also run the other way when it comes to extremism. Extremists will make a religious statement and when someone points out that there are many believers who don't believe the extremist's viewpoint, the moderates are deemed to be not true believers (i.e., Christians who support gay marriage are not "real Christians" or Muslims who support women's rights are not "real Muslims"). Modern pagans do it all the time, perhaps even more than other religions, due to the fact that there is no agreed-on orthodoxy for the whole group, with some well-established practices in one setting being considered unpalatable in others. Silver Ravenwolf, one of the best selling "leaders" of neopagans, has done this with multiple ancient, well-established practices.
It's a tricky business, as being a member of a religious group, to the minds of those involved, encompasses adhering to a certain standard of behavior. For example, charity can certainly be called an essentially Christian ethic, considering the emphasis that Jesus placed on it. The man himself would most definitely disavow the greedy and "What's mine is mine" mindset of many right-wingers who call themselves Christians. However, strictly speaking, a Christian is defined as "one who professes belief in the teachings of Jesus Christ"; there's no rule saying they have to do it right.
Another problem has to do with conversion. EG:
Ann: "No member of Religion X has ever converted to Religion Y.
Bob: "But what about Person Z, member of Religion X? Didn't he convert to Religion Y? "
Ann: "Oh, but Person Z wasn't a TRUE member of Religion X!"
 In nonreligion
Atheists can also be guilty of the fallacy, such as someone hypothetically exclaiming that "true atheists" don't believe in ghosts or UFOs when such disbeliefs actually have nothing to do with an atheistic philosophy (although they can be linked by concepts of observational evidence and rationalism).
 In politics
“”Argentina was then under the rule of these neo-Nazi generals, and I was sent La Prensa from Buenos Aires, the big newspaper in Argentina−there was a big article saying, "You can't read this guy's linguistics because it's Marxist and subversive." The same week I got an article from Izvestia in the Soviet Union which said, "You can't read this guy's linguistics because he's idealist and counter-revolutionary." I thought that was pretty nice.
NTS can be used to uphold positive, neutral, or negative stereotypes by portraying people who do not conform to them as exceptions. An example would be claiming that feminists, being "well-educated and having strong opinions about gender issues," do not speak for "typical" women. It is also commonly used as a form of name-calling (i.e. "Real men eat meat", "Real americans don't question the existence of God", "Real artists don't use a computer", etc.)
Phrases such as "un-American," "un-Christian", "un-Islamic" or "inhuman" are widely used in politics and media to distance oneself from a subject, defining them as outside the bounds of what the speaker considers to be truly 'American,' 'Christian', 'Muslim' or 'human' behaviour. These phrases strongly suggest NTS is in use, since the use, for example of "un-American" to describe specific political activities by some American citizens implies some special definition of "American" beyond mere nationality.
In recent years with the advent of the Tea Party Movement, the turn of phrase "Republican in name only" (RINO) has come into more prominence from people who want to disassociate from other people of the party. The trouble with this phrase is that it is not useful at all since its use tends to be a replacement for "Republican I don't agree with, despite being in the same party." People who use this phrase tend to throw it even if there is only one issue the supposed RINO doesn't toe the party line on, such as being Pro-choice. The term of art Cuckservative has similarly been used for otherwise conservative persons who believe that racial and gender inequality persist in the United States. This also exists on the other side as well, but having terms that identify subgroups like Blue Dog Democrat is far less damning and more useful.
