Thomas Sowell made a correct prediction, based on his clear anti-racist eye sight.
In a book he wrote in the late 1980s, Professor Sowell encouraged black students to pick a college where they would be comfortable in the higher ranks of academics, rather than at a school that lowered entrance requirements for blacks.
Sowell argued that black students accepting a low class rank at an elite school with high status was counter productive.
Sowell was right, based on recent law school research. Blacks admitted because of affirmative action, who were at the bottom of the class had a higher drop out rate than comparable black students who were at law schools where they were in the upper class ranks.
Makes sense, and the data, from Richard Sanders (UCLA) supports Sowell's clear anti-racist vision of the world.
