Why would you believe anyone's estimates of the IQs of historical figures? Doesn't it seem likely to you that successful people, or those the estimator likes or respects, will have their IQs overestimated, at least relative to the others? Further, people do a poor job at estimating the intelligence of those who are smarter than they are.

I know many highly intelligent people who are fantastic at puzzles and games and making sharp observations, yet who have had mediocre success in their professions. I know many extremely successful people whose IQs are below 130, sometimes much lower. Intelligence is not the same thing as talent, and both are merely partly correlated with accomplishments.

I feel dumber after reading your post.
