lisab said:Feynman's IQ was 125.
That number and that factoid about Feynman are often bandied about by those skeptical of IQ tests. I believe it's almost certain that that number was an aberration, caused by a multiplicity of factors - a poor test (maybe one emphasising verbal ability, or prior recall of facts/trivia), Feynman's lack of seriousness in taking the test and/or well-known antipathy toward psychometrics in general.
You only have to read his autobiographical "Surely you're joking, Mr. Feynman!" to know how he viewed shrinks and their ilk.
Psychometrics wasn't that far along those days, and there were plenty of bad tests floating about. I'm willing to wager that a properly administered "culture-fair" modern test that tests symbolic logic and reasoning ability would have demonstrated Feynman to have had a VERY high IQ (at least 160), provided Feynman were serious about taking it. Unfortunately, we'll never know.
I believe that IQ is correlated with cognitive ability, and the top achievers in any intellectual field will have high IQs. It's certainly not the only factor that's important - motivation, emotional adaptability (I hate the catchphrase "emotional intelligence") and other factors play very important roles. But it's unnecessary to measure IQs to judge the worth of these top achievers, because their achievements speak for themselves.
IQ remains important in stratifying the cognitively subnormal, but it's really fairly useless in quantifying supernormal cognition, except to provide underachievers with dubious bragging rights.
