The 2012 estimate from SATs was about 128, since the 1994 renorming destroyed the old relationship between the SAT and IQ. Our average SAT (on 1600) was again about 1470, which again maps to less than 130, but not by much. (And, again, self-reported average probably overestimates actual population average.)

It's very interesting that the same mistake was boldly made again this year... I guess this mistake is sort of self reinforcing due to the uncannily perfect equality between mean IQ and what's incorrectly estimated from the SAT scores.

According to Vaniver's data downthread, SAT taken only from LWers older than 36 (taking the old SAT) predicts 140 IQ.

I can't calculate the IQ of LWers younger than 36 because I can't find a site I trust to predict IQ from new SAT. The only ones I get give absurd results like average SAT 1491 implies average IQ 151.
