Race and IQ debate, responses to The Bell Curve. I don't recall these responses since I read the book so long ago, but the original Bell Curve was stupid. Even if it is true that Race X has an average IQ of perhaps 5 points lower than the average IQ of Race Z, what difference should this make to social policy? The overlap between the two populations is much larger than the difference. There is little, if any predictive value since, lacking other information, you cannot guess the IQ of a given individual based on their race. Nor is IQ the sole determinant of accomplishment or social value. Would you rather be friends with a sociopath of 130 IQ or a normal individual of 100 IQ? An ambitious person of average IQ may accomplish much more than a slacker of high IQ. And so forth. There may be value in measuring the IQ of individuals when deciding whether they will benefit from or be suited for particular education or training. But averages of races are just pointless attempts to justify prejudice.

Worth reading in light of the re-emergence of 'the bell curve' debate and the re-emergence of Charles Murray
