> It's true - black people tend to underperform relative to their SAT.

Its actually a lot more complicated than that; the degree to which each objective factor predicts grades (and the degree of difference in expected college grades each unit change in the factor represents) differs by race, income, and other factors. (In the case of SAT scores, higher SAT scores mean more in terms of better college grades than they do for whites.)

So the average black student underperforms based on their SAT scores -- but that is less true (and eventually the opposite of the case) for blacks with higher SAT scores.

> So your real critique seems to be that SAT is unfair because it gives a non-predictive boost to blacks and hispanics.

No, my real critique is that the assertion that without AA, existing admissions would be meritocratic is unsubstantiated, and that there is plenty of reason to be skeptical of it.

And I will maintain it until someone presents a coherent definition of the merit sought and evidence that supports the claim based on that definition.

...that is less true (and eventually the opposite of the case) for blacks with higher SAT scores.

From the cited article: "Blacks with the highest SAT scores and high school GPAs...are those underperforming the most.

Do you have have data showing the opposite? Note that your source on the other thread did linear regression, so it can't possibly capture this effect.

No, my real critique is that the assertion that without AA, existing admissions would be meritocratic is unsubstantiated...

Your sole evidence for this is a source stating that SAT and GPA are good predictors of college performance, but SAT and GPA plus a penalty for black people is even better.
