This teacher is definitely off the wall and his views on slavery around the bend. I doubt that he's capable of giving black kids a fair shake (but that's not really my right to say).

But differential performance by various racial and ethnic groups on a variety of tests and measures of achievement is undeniable...and the causes in dispute.

30 years prior - in "Ethnic America" - Sowell attributed many black problems to the topography and climate of Africa. 15 years ago his criticism of "The Bell Curve" was limited to a claim that Herrstein and Murray didn't give enough weight to "IQ creep". Here's a nice review of his current offering.

I don't know the state of the dispute today but I very much doubt it's been resolved.

What's most interesting to me are the differences in results of tests that have no virtually no verbal/math/cultural component, such as measuring times to react to light changes and times to move to press another button.
