It is claimed that there is a certain kind of logical fallacy, dubbed "No true Scotsman". But the logical fallacy is only in its ever being applied, what I hereby officially dub as the "the 'No true Scotsman' logical fallacy applies here" logical fallacy. Or the TNTSLFAH fallacy, for short.
As a general, overall good rule, those who have not progressed to even intermediate reasoning skills should definitely not be trying to wield logical fallacy application. Here, dear reader, is a comprehensive, one-question test for you to see where you fall/il:
1. Bill Dog wrote that for NTS, "the logical fallacy is only in its ever being applied". What he means here is:
A. NTS is strictly absolutely never applicable.
B. NTS is, in the vast majority of times, inapplicable.
C. NTS is always applicable.
D. Monkeys are funny.
There, now score yourself; if you answered:
C: You have the reading comprehension of a Slashdotter.
D: You're a walking argument against the legalization of drugs.
A: You have the reasoning skills of a Slashdotter.
B: Congratulations, you're at the least a halfway-intelligent human being. (You rare specimen, you!)
Wikipedia, the ultimate authority on everything, speaketh amongst thusly on NTS:
When faced with a counterexample to a universal claim,
I like the dramatic "faced with". But it never applies. For example, if someone says "Strictly speaking, I am literally saying that *ALL* Mexicans love to eat beans", then certainly the presence of a single counterexample of that would be jarring for the person. However, no one says that (or esp. even means that
So in fact, it is the person who actually thinks NTS applies to a given scenario who's committed the error in reasoning. As in, not reasoning properly about human communication.
There is at least one other notable additional dimension in which NTS can be misapplied. As in, you can be a semi-normal human being and have grasped the natural, intended meaning just fine, but still err in thinking that NTS applies, thusly:
No true Scotsman is [...] an ad hoc attempt to retain an unreasoned assertion.
Therefore, NTS is only applicable to "unreasoned assertions". And not, for example, "extensively observed assertions". So take someone who's been surrounded by Mexicans all his life, and has been really paying close attention to them for the last couple of decades. His uttering "Mexicans love to eat beans" is not an assertion based on reason. He didn't say "Yada yada yada, ergo Mexicans love to eat beans". So application of NTS here would be misapplication, and a demonstration of bad reasoning in having thought otherwise.
