The authors are Richard H. Sander and Stuart Taylor, Jr., and the subtitle is How Affirmative Action Hurts Students It’s Intended to Help, and Why Universities Won’t Admit It.
Here is the book’s website, and a summary:
… law professor Richard Sander and journalist Stuart Taylor, Jr. draw on extensive new research to prove that racial preferences put many students in educational settings where they have no hope of succeeding. Because they’re under-prepared, fewer than half of black affirmative action beneficiaries in American law schools pass their bar exams. Preferences for well-off minorities help shut out poorer students of all races. More troubling still, major universities, fearing a backlash, refuse to confront the clear evidence of affirmative action’s failure.
As you may know, the Supreme Court starts hearing oral arguments on affirmative action on October 9th. I have not much followed the empirical debate on affirmative action, but it seems to me this is likely the best recent book on the “anti” side. On the pro side, you can read The Shape of the River, by William Bowen and Derek Bok.
