I have no clear memory of ever having been administered an IQ test, although there's some possibility that I was given one as part of the battery of tests which I vaguely recall as a preliminary to my being placed in some "gifted" program after 5th grade, in my passage through American grade school. I never sought one out afterward, but I didn't always think (as I think now) that IQ is bullshit; there was some span of childhood years in which I accepted the concept uncritically, and wondered about what my score was. But thanks to the enormous cult following that "IQ" has gathered unto itself, I can look up my 1989 SAT score (1550) in a table (if you're curious, https://www.iqcomparisonsite.com/satiq.aspx) and get an estimate of about 150. Whatever that's actually supposed to mean. It's never been very clear to me how a test that chiefly rewards rote memorization and cramming, like the SAT, is supposed to be representative of "intelligence"—not in the grandiose, all-encompassing sense by which an elite-class nerd means "intelligence", anyway.
Occasionally I've run into someone on Twitter—it's always been on Twitter—who brags about their IQ, and I wonder where they get their figures, assuming that the guy—it's always been a guy, putatively—didn't just make up a nice high figure on the spot. I've generally assumed that the sort of programming geek or financebro who boasts of their high IQ has either done what I just did, i.e. went to a lookup table that purports to map a commonplace standardized test score to IQ, or they answered a few multiple-choice questions on a website as if they were trying to find out what Vampire: The Masquerade class best suited them, except that they're trying to find out how "intelligent" they are. I suppose the next time I see someone with a specific brag about their IQ, I'll ask them where they got the number.
That's assuming I bother with Twitter again. Which I probably will feel forced to do anyway.
