HN discussionI saw numbers for supreme court justices a couple years ago but I can't find it. https://pumpkinperson.com/2015/07/26/anne-roes-study-of-extr... Says Nobel prize winners had an average IQ of 155, which is a 1 in 4000 score that couldn't be driven by just sub 100 effects. Hard to find IQ scores on really high performers, I guess it's hard to convince a CEO or a supreme court justice to take an IQ test.

HN discussionThe article basically says when you look at a 1000 really smart 11 year olds you don't get any Nobel prize winners. Which is a pretty obvious straw man because the base rate of Nobel prize winners is 1 in a million, plus childhoold IQ doesn't perfectly correlate with adult IQ. For instance a group of children with an average IQ of 150 will have an average IQ of 130 as adults. https://pumpkinperson.com/2015/07/26/ann…
