Three years ago, UCLA law professor Richard Sander published an explosive, fact-based study of the consequences of affirmative action in American law schools in the Stanford Law Review. Most of his findings were grim, and they caused dismay among many of the champions of affirmative action — and indeed, among those who were not.Easily the most startling conclusion of his research: Mr. Sander calculated that there are fewer black attorneys today than there would have been if law schools had practiced color-blind admissions — about 7.9% fewer by his reckoning. He identified the culprit as the practice of admitting minority students to schools for which they are inadequately prepared. In essence, they have been “matched” to the wrong school. …

Now Sanders is trying to continue his research, but some are trying to block him from data that ought to be publicly available.

Take William Kidder, a University of California staff advisor and co-author of a frequently cited attack of Sander’s study. When Mr. Sander and his co-investigators sought bar passage data from the State Bar of California that would allow analysis by race, Mr. Kidder passionately argued that access should be denied, because disclosure “risks stigmatizing African American attorneys.” At the same time, the Society of American Law Teachers, which leans so heavily to the left it risks falling over sideways, gleefully warned that the state bar would be sued if it cooperated with Mr. Sander.Sadly, the State Bar’s Committee of Bar Examiners caved under the pressure. The committee members didn’t formally explain their decision to deny Mr. Sander’s request for this data (in which no names would be disclosed), but the root cause is clear: Over the last 40 years, many distinguished citizens — university presidents, judges, philanthropists and other leaders — have built their reputations on their support for race-based admissions. Ordinary citizens have found secure jobs as part of the resulting diversity bureaucracy.If the policy is not working, they, too, don’t want anyone to know.
