P6 fights the stupid. And dude, if folks teased you in school, don't take it out on all the rest of us black folk,ok? Just one comment, though. One other possible confound is that high GPA black kids may end up being placed in honors and AP with the white kids. I did talk to other blacks in high school, but mostly in the few classes I had on the regular track, in the lunch room, and outside of school. I was tracked with nearly all whites, so thus, I had more white friends than black. I'm not sure if they removed this possible confound. Also, what if blacks who go to schools with more whites are richer(and thus more likely to have high GPAs)? That could also confound the research.
