There are consequences of every policy ever developed. As we are human, and not omniscient, there will be adverse consequences. In an honest society, these will be discussed. The correct approach to bad outcomes is to name them, and work out how to correct them.
But we are too neurotic, as a society, to be honest. Quotas for admission to elite courses is starting to mean that you had different populations, and here the USA is an example of what not to do.
In short, the affirmative action process, as it plays out, inevitably puts the black students at schools like Georgetown into a separate intellectual category and sets them up for failure. The issue is particularly acute at just-short-of-top-tier places like Georgetown. You can well understand why black students there might come to feel isolated. And thus this has become a phenomenon that everybody knows is true, and that has to be true, and is obvious, and yet it cannot ever be mentioned. As Lott puts it:
Some simple, obvious facts are too politically incorrect for academics to state publicly.
I don't really care if we produce a bunch of more shoddy lawyers. We have enough shoddy lawyers anyway, and the sensible ones do something else.
I do care when this affects medical schools, engineering schools and other places where if you make a mistake people die. Right then, right now, without any appealate court.
