there is no affirmative action scoring, although the writing section may have a small bias if the writer can convince the marker that she is black. the math and verbal portions are scored the same for everyone.
it is the race norming afterwards with the scores that upsets people. a black 1200(1800) will get you into elite schools that a white 1500(2250) wont. unfortunately those that get in under preferences often perform at the standard of their scores. which only serves to preserve the stereotype of black inferiority.
In the early 70s I taught at two private liberal arts colleges in Mississippi. One was historically black and the other had the only Phi Beta Kappa chapter in the state (a couple of years later Ole Miss got the Beta Chapter; you got know that stuck in their craw!).
Anyway a few of us taught classes at both (I got swapped out for an accounting prof, they were short a finite math instructor and statistician) and most had a few students from the other college from time to time from a cross-enrollment agreement. Consensus was that the black students were more intelligent, but had inferior backgrounds. It made sense, as a segregated educational system did a lousy job of preparing black students, and the black students that made it to college had to have compensated for the inferior education, and they sure didn't do it by having rich parents.
Needless to say, the white students had far better SAT scores, but the black students had better GRE scores. People who think that SATs say something about intelligence by race need to explain the GRE scores.
