Blacks as a group consistently score lower than whites on standard IQ tests. That is a fact no one can dispute. But the reason for the discrepancy has become a matter of heated dispute -sparked largely by the widely publicized theories of Psychologist Arthur Jensen and Physicist William Shockley. The two men suggest that genetic factors account for the differences. Others, like University of Pennsylvania Anthropologist Peggy Sanday, insist that the differences are environmental. Last week Sanday buttressed her case by reporting the results of her own study...
...article I even allowed that the heritability of IQ among white Americans could be 100 per cent for all the difference it makes to the question of race. I was willing to grant a high heritability of IQ for American whites because, for the purpose of exposing Mr. Jensen's particular brand of nonsense, it was not worth disputing...
...book The Fallacy of I.Q. (edited by C. Senna and published in 1973), the same Professor Lewontin wrote "the weight of evidence from a variety of correlations between relatives puts the heritability of I.Q. in various human populations between .6 and .8. For reasons of his argument, Jensen prefers the higher value but it is not worth quibbling over. Volumes could be written on the evaluation of heritability estimates for I.Q. and one can find a number of faults with Jensen's treatment of the published data. However, it is irrelevant to questions of the failure of compensatory education, whether...
...error of confusing the heritability within a population with the causes of differences between populations was clearly made by Arthur Jensen in his famous article in the Harvard Educational Review, when he tried to infer from heritability studies within the American white population the causes of differences between races. This elementary blunder would not be tolerated in a freshman class in statistics or genetics. We may well wonder how it came to be made by a professor! Precisely the same error is made in arguments about the genetic inferiority of the working class. By referring over and over again...
...attention (at universities, in the media) through spectacle rather than through airing their views in rational debate. We come to assume that speeches and discussion groups are rational because they are set in the university--where all sides are heard--and involve acknowledged experts. But in the case of Jensen-Shockley-Herrnstein one side is heard more often than others, and in the case of Shockley alone, no acknowledged expert is involved...
