>>12200322I got 125 when tested for the 'gifted' programs in middle school, then scored 3 SD above the mean a few years ago. The tests were very different though, the one when I was a kid was mostly visual questions and puzzles with wooden blocks, and the other one was all multiple choice and had more of a verbal component. I think I have fairly strong verbal intelligence, but really excel at visualization and abstraction of ideas, though not amazing at mathematical abstraction.
IMO IQ tests are kinda silly. I haven't researched how the tests are developed, but it seems to me that it tries to test a specific type of intelligence, and I'm not even sure its good at doing that. If I had the choice I would be a 3 SD above the norm for creativity instead of IQ any day. I'm getting two degrees in Neurobiology and Physics this spring, but a significant part of me wants to drop science and spend my life making music in a peaceful house in the country.
But to answer your question OP, Feynman was a true mathematical genius. I know enough physics to realize I would never be able to come close to anything he accomplished in the field. His IQ might have been 125, but that doesn't mean shit. He was a genius.
