Um, Affirmative Action. Also tail ends of distributions.

I was under the impression that AA applied to college admissions, and that college graduation is still entirely contingent on one's performance. (Though I've heard tell that legacy students both get an AA-sized bump to admissions and tend to be graded on a much less harsh scale.)

Additionally, it seems that there's a lot of 'different justification, same conclusion' with regards to claims about black people. For instance, "black people are inherently stupid and lazy" becomes "black people don't have to meet the same standards for education". The actual example I saw was that people subconsciously don't like to hire black people (the Chicago resume study) because they present a risk of an EEOC lawsuit. (The annual risk of being involved in an EEOC lawsuit is on the order of one in a million.)
