What Mr. Sander and Mr. Taylor have accomplished here is incredibly impressive. The authors have done an excellent job of pulling together the available research, and Mr. Sander in particular has been dogged in his pursuit of fresh numbers. He’s even used lawsuits and Freedom of Information Act requests to extract data from admissions departments.
Mr. Sander summarizes the excellent research he’s done on law schools, for example. Black students admitted under racial preferences tend to drop out at much higher rates than black students who attend schools that match their qualifications, and black law school graduates are far more likely than whites to fail their bar exam. By Mr. Sander’s estimation, more blacks would succeed in becoming lawyers if they attended schools that would accept them without preferences.
