> There was a school district in a small town that for the first time gave IQ tests to all of the children in some younger age group, I think around 7 or 8. The results showed a several point difference between the white kids and the Black kids. The district wrote this off as due to cultural bias in the tests.

A "several point difference" sounds like an unusually narrow gap - depressed white scores, maybe? On an unbiased test with no environmental problems, you'd expect to see a gap of around 15 IQ points.
