But none of these things is a matter of talking about how clever we are; they're about talking about what to do with our cleverness. The thing a bunch of people are skeptical about the value of is yet another attempt to quantify exactly how smart LW's population is (according to some particular numerical measure of some particular kinds of smartness), which is not at all the same thing.
The latest survey shows that the average LessWronger who entered his SAT or ACT is roughly in the top 0.11%. This is insanely high. For comparison, top 2% can be Mensa members. I do not know the correlation between SAT/ACT and IQ, but I know it's fairly high. Anyway, I'm very curious to see the average score on a real, culture-fair IQ test. Those are the only two tests that are free, online, correct and culture fair, from what I know.

Many people would prefer not to have people knowing their scores. That's great, but please please please do post it anonymously. Especially if it's a low one, but not if it's low because you rushed the test.
JCTI might take a while, so I recommend keeping your answers on Notepad in case you want to leave it and continue later.
Edit: I have included polls, thanks to the commenters.
