Show me the number of 90-95 I.Q. people who have graduate with a four year degree with honors.<. Obama, Durbin and Biden became lawyers but that's an anomaly too. It is possible to be of lower I.Q. and earn a college degree.
My guess is that Feynman didn't care much and basically flubbed the test on purpose or due to lack of motivation. That's why i've always been dubious of seeing this person or that person touted as the smartest in the world because of some IQ score: there are those who are highly motivated to score well and then there are others who are content to let their work testify to their genius. Feynman i'm sure was in the latter category and probably got a kick out of scoring only 125.
