Racism does not explain differences

Tom Sowell writes in the WSJ:

For most of the history of this country, differences between the black and the white population--whether in income, IQ, crime rates, or whatever--have been attributed to either race or racism. For much of the first half of the 20th century, these differences were attributed to race--that is, to an assumption that blacks just did not have it in their genes to do as well as white people. The tide began to turn in the second half of the 20th century, when the assumption developed that black-white differences were due to racism on the part of whites.

Three decades of my own research lead me to believe that neither of those explanations will stand up under scrutiny of the facts. As one small example, a study published last year indicated that most of the black alumni of Harvard were from either the West Indies or Africa, or were the children of West Indian or African immigrants. These people are the same race as American blacks, who greatly outnumber either or both. ...

What then could explain such large disparities in demographic "representation" among these three groups of blacks? Perhaps they have different patterns of behavior and different cultures and values behind their behavior. ...

Disparities between Southern whites and Northern whites extended across the board from rates of violence to rates of illegitimacy. American writers from both the antebellum South and the North commented on the great differences between the white people in the two regions. So did famed French visitor Alexis de Tocqueville.

None of these disparities can be attributed to either race or racism. Many contemporary observers attributed these differences to the existence of slavery in the South, as many in later times would likewise attribute both the difference between Northern and Southern whites, and between blacks and whites nationwide, to slavery. But slavery doesn't stand up under scrutiny of historical facts any better than race or racism as explanations of North-South differences or black-white differences.

I think that it is amazing that Harvard can give an assortment of lofty justifications for affirmative action, and then fill its black admissions quota with students from Africa and the West Indies.
