Take that with a grain of salt. According to IQ scores, the average person in the 1930s was within one standard deviation of litetally being retarded, and when Feynman was alive, he was a mere two standard deviations above the norm. Personally I dont believe IQ correlates with g. And anyways, how can you even define g in the first place, let alone IQ? There seems to be some colloquial tautology here: Ddoing so by defining it as IQ, then testing for IQ and calling that g. It is ridiculous. From Wikipedia: >Ulric Neisser estimated that using the IQ values of 1997, the average IQ of the United States in 1932, according to the first Stanford–Binet Intelligence Scales standardization sample, was 80. Neisser states that "Hardly any of them would have scored 'very superior', but nearly one-quarter would have appeared to be 'deficient.'" He also wrote that "Test scores are certainly going up all over the world, but whether intelligence itself has risen remains controversial."
