False carbon dating reads
It is the “leading international body for the assessment of climate change,” * The first IPCC report (1990) contains the following graph of average global temperature changes over the past 1,000 years based upon proxies.
It shows a “Medieval warm period” that was warmer than the present era and a “Little Ice Age” that was cooler.
By extension, you aren't considered a real fan of the genre if you don't know of these works.
Sometimes, when dealing with a Dead Horse Genre or another sufficiently ghettoized field, the fallacy is used to try and distance a well-liked entry from it.
Works or creators are discredited as not part of the genre due to not living up to arbitrary standards (or just being popular).
The study found that water temperatures increased on average by 0.23ºF (0.13ºC) per decade between 19, while air temperatures cooled by 0.02 to 0.09ºF (0.01 to 0.06ºC) per decade during the same period. examined the locations of 1,007 of the 1,221 monitoring stations used to determine average surface temperature changes across the continental United States.In real life, it's most commonly found in arguments about politics, race, nationality, or religion, usually when it comes to perceived stereotypes that something negative "can only be done" in a specific region or group of people (especially The Rival) and the accuser's own group; with of course ignoring the fact that it can.Essentially a form of Begging the Question, in that, to accept the argument that No True Scotsman would do X, one must accept that the definition of "True Scotsman" includes "would not do X." It's also a good example of Confirmation Bias in action.In regards to Real Life examples, what may be considered as "a true/not a true (whatever)" often relies on personal interpretation which can result in heated arguments, so let's not go there.It's perhaps also worth mentioning that, among those who wear the kilt, a "True Scotsman" is the humorous term for someone who is confident enough to go commando.
So if someone asks "Are you a true Scotsman," it might not be this fallacy— they may just be wondering about your underwear.
