average IQ of 125-130
I find it interesting that you're so sure about your original estimates for the IQ of rationalist public intellectuals. While you're trying to figure out why there's a difference between the average rationalist IQ and that of the more notable rationalist intellectuals, you're taking for granted that your estimates are right. Maybe it's worth considering that your initial guesses might not be as accurate as you think.
Shouldn't you trust high N, consistently-replicated survey data more than quick-and-dirty estimations?
You probably don’t know, but 135 is at least the 99’70th percentile, so the difference in intelligence only progresses with increasing IQ, dear author. Let me remind you that there is a difference. In addition, the rationalists in fact did not discover anything new, but that is not their task.
What this says more is that perhaps IQ isn't actually an indicator of being right. Or successful. Maybe it needs a certain personality to work...
Lex Fridman confused and euphoric to see that he somehow made it onto this list
I get your rationale for his IQ but listen to him speak on his podcast for just a couple minutes and you get very different impression of the man..
