> They haven't been shown to be biased, merely that blacks score lower. Extensive research has show that IQ tests have equal predictive power for blacks and whites.
Now, now now. You've forgotten Political Logic.
Political Premise: There are no significant differences in intelligence between blacks and whites.
Empirical Premise: Blacks score lower than whites on IQ tests.
Conclusion: IQ tests are biased.
The first rule of Political Logic is to never question the political premise!
Oh, look: an appeal-to-emotion on "political logic" consisting of ignoring eight hundred years of the racist "political premise" (extending to present day) that whites are superior to blacks, followed by straw man, followed by false premise.
Ignoring? Not at all. I'm just pointing out that the notion of racial differences is so taboo in contemporary academic culture that it's impossible to honestly discuss the question. To honestly address the question, you have to be open to the possibility of any answer, which frankly we aren't. If certain racial differences don't exist, that's fine, but if they did exist, no one would say so anyway. So we can't take the claim that racial differences don't exist at face value, because that's the only palatable conclusion open on the question.
The taboo is a completely understandable and largely inevitable reaction against the open and largely fallacious racist claims of academics in the recent past, but it's still a taboo that inhibits honest inquiry. Perhaps in another 50-100 years.
