I'm speaking of a specific way of being irrational which is highly popular here: to explain normal behaviour in terms of "cultural memes" and "pattern matching" (misusing meanings of both), while neglecting the fact that e.g. in this specific instance, the world being what it is, if you hear that a man is training his wife, that probably implies physical abuse, whereas if you hear that a wife is training the man, that much less implies abuse, and thus one normally infers abuse from the former but not the latter (which may be unfair, but definitely isn't wrong in any other sense than fairness).
