A recent study shows that, when you hold constant for nearly everything imaginable, minority students, on average, receive lower law school grades than white students. This has some commentators , who find the study "carefully done" and compelling, wringing their hands about what can be done.
Increasingly I think white liberals want to classify deep social issues as exclusively matters of race. This means they can continue to ignore matters of class -- of which there is a great variety within races -- more generally. The reason for this is easy. Class differences, more than race differences, are responsible for their successes and we would not want the legitimacy of their success questioned, now would we?
In fact, something makes me uncomfortable about the use of race as a variable in a study about grades or scores that are blind graded. Some of that discomfort comes from the possibility of stereotyping -- minority students do worse can too easily become all minority students do worse. Or, worse yet: Since you are a minority student, you will do worse.
