"whom". By us? By our culture? By the media?

Education attainment? Income? Interracial Marriage? Sure a stereotype isn't evidence. But my point is that both the nation at large "stereotypically" and alumni ( after interviewing asians ) both rated asian personalities at the same level or better than other races. Given that evidence, why did admissions officers rate asians a couple of standard deviations below other races?

> something about the personalities of individuals.

But we aren't inferring personalities of individuals. We are inferring personalities of racial groups.
