If KH has said he was one of the greatest 20k financial minds I wouldn't have disagreed, and if he said he was one of the greatest 20k analytic minds today, I wouldn't have argued.
Based on my understanding of science and testing, I don't see how it couldn't be undetermined. For much more simple systems which are much better modeled, I and other physicists are have a very hard time determining differences of that nature. I expect that there is a difference that you can be sure about between 170 and 140, though.
You aren't arguing that those with genius achievements don't have very high IQs (greater than 140, for example). You are arguing that they had IQs uniformly in the top of the distribution (in the top 20k, say).
Francis Crick has an IQ of 115.
Bobby Fischer has an IQ of 187.
James Woods an IQ of 180.
Kim Ung-Yong an IQ of 210.
Marilyn vos Savant with an IQ of 228 (more accurately 190, I think).
Einstein was not tested, but in the method that people use to assign scores to people would not have had a high score.
Most studies I have seen agree that above some point (definitely above 160, and some even say below 155) differences in IQ have no real meaning. From this I would guess that it becomes less useful in comparing people with scores above 140.
