Dare dey go agin, dissin minorities. Gonna lower dare self-esteems.
I would venture to say that if a student scores low on the SAT, his self-esteem is lowered, no matter how high his assigned racial group scores on average. If a student scores high, his self-esteem will be fine, no matter how low his assigned racial group scores on average.
The problem is, when his "assigned group" scores low on average, his self-esteem isn't lowered, but his chances of getting a good job are.
