In my view, there is no need to test 'intelligence' or even to posit such a category. What's the point of inventing and measuring it, except that administrators might want it for the purposes of educational sorting and hierarchizing with an appearace of scientific objectivity and that 'intelligence' business helps to shore up the ideology of meritocracy?
Further, why even _ask_ questions such as, 'Do different races have different levels of intelligence?' I think that racism is inherent in questions like the above.
