With all of the affirmative action and minority scholarships, the Negro College Fund, and the intense recruitment of blacks for diversity, there is no reason for the grim statistics quoted other than the obvious. The Bell Curve states the facts and one cannot make a silk purse out of a sow's ear. Unfortunately, you are speaking the truth that very few admit openly. Another reason is that many blacks are attending top colleges when they are only qualified to attend mid-level colleges. In other words, the black kid who can make the dean's list at NJ's Rutgers U. would barely make it through Princeton.
The Bell Curve as one man's set of 'facts'. I am continually amazed at how some FReepers just trod out one researcher's book to entertain their own prejudice.
