IQ and other psychometric assessments are not actually backed by hard science but vibes

so when someone brags about having a "genius level IQ", just write them off as a narcissist

sincerely, your local psychologist turned software engineer

humans and other animals are complex systems, while there are diagnostic tests which measure a degree of performance in specific skill areas, you can't really boil someone's intelligence down to a single number: the person who sucks at math might be a great strategist, for example

incidentally: psychometric evaluation is heavily biased toward performance in math and other hard logic categories in general, so-called IQ tests especially.

also while I am dropping truth bombs: Mensa has problematic connections with the eugenics movement

@ariadne The Mensa test is very good at selecting the kind of person who would take a Mensa test.
