Affirmative Action Prevents Binge Drinking?

Campuses where more than 21% of students come from "minority" groups have less binge drinking according to a new Harvard University study--only 44% of students were heavy drinkers compared to 53% for campuses with less diversity. The new study may provide the biggest stretch for a justification for affirmative action ever proposed. "Such an approach could add a twist to the affirmative action debate raging at predominantly white universities and education think tanks nationwide," suggests the Washington Post. BTW, binge drinking is defined as more than 5 drinks in succession for guys and 4 for gals.
