Imagine environmental & cultural factors explained the black:white intelligence difference. It would be magical & not follow any internal logic. Why would blacks & whites matched for IQ have a mean 0.5 SD dif. in visuospatial IQ?

Or:

"When you compare black and white mean scores on a battery of subtests, you do not find a uniform set of differences; nor do you find a random assortment. The size of the difference varies systematically by type of subtest."

"Some of the largest differences are found on subtests that have little or no cultural content, such as ones based on abstract designs."

Or:

"Digits-backward is much more g-loaded than digits-forward. Try it yourself and you will see why. Digits-forward is a straightforward..."

"...matter of short-term memory. Digits-backward makes your brain work much harder."

"The black-white difference in digits-backward is about twice as large as the difference in digits-forward."

"It is a clean example of an effect that resists cultural explanation. It cannot be explained by differential educational attainment, income, or any other socioeconomic factor. Parenting style is irrelevant. Reluctance to “act white” is irrelevant. Motivation is irrelevant."

"There is no way that any of these variables could systematically encourage black performance in digits-forward while depressing it in digits-backward in the same test at the same time with the same examiner in the same setting."

"Creating double standards for physically demanding jobs so that women can qualify ensures that men in those jobs will never see women as their equals. In universities, affirmative action ensures that the black-white difference in IQ in the population at large is brought..."

"...onto the campus and made visible to every student. The intentions of their designers notwithstanding, today’s policies are perfectly fashioned to create separation, condescension, and resentment — and so they have done."
