When Washington, D.C., councilman and former Mayor Marion Barry this week said that whites need to be “more open-minded” about African-American politicians, claiming “blacks are more open-minded than” whites, he was suggesting that whites can’t do what blacks do — embrace the other race.

But a new study of 212 black college students made available to Secrets found little open-mindedness: Blacks don’t like it when other blacks associate with whites, to the point of refusing help to an African-American experiencing “a run of bad luck” — just because they have white friends.
