@cicerone imposter,
Many stupid things have been written by Harvard professors. The guy who wrote the piece I believe you were referring to was not a Harvard professsor, he was William Shockley, a scientist, formerly with Bell Labs and the inventor of the transistor.
In fact Shockley was reporting the real results of IQ tests, which are a reasonably accurate, but imperfect, measure of intelligence. The reported results themselves were accurate descriptions of the data on which they were based, but more was made of the real, but small average difference between blacks and others than many observers thought warranted. More importantly Shockley's speculations that the measured difference was surely the result of a genetic difference, and not merely the consequence of changeable social and family conditions, was not supported by any scientific evidence at all. In fact there are readily observable social & cultural factors that themselves could make all the difference. Denying their existence is common in politically correct circles, but that is certainly just as stupid as Shockley's jump to his conclusion.
