        That's the worst sentence in a good article. Biased is a loaded word. Being correlated with race doesn't by itself render a practice (and thus a model control) illegitimate. Business necessity is a valid defense to disparate impact claims.

        If the only Xs in your model other than race are orthogonal to race, what do you think their inclusion does to the size of the estimated race difference?

        Holy smokes. I knew there wa a disparity between acceptance rates between Blacks / Hispanics and Asians... but not that much. Very dispiriting for an Asian parent with a high school aged student.

        but isn’t a core tennant of affirmative action to push aside fairness and impartiality? it’s implicit that the standards be skewed to benefit certain groups at the expense of others. @cmonnn_mannn “The university’s reputation for fairness and impartiality emerges bruised”

        Affirmative actions was SUPPOSED to be for fairness and impartiality, in getting people who might otherwise not meet the criteria because of factors outside of their academic capability, for schools, or their workplace acumen, for business hiring. It's not been, for a long time.

        ummm not sure of your point here dude but if we’re saying Group A needs an SAT of X for admittance while @ the same time saying Group B needs X - 30% then we’ve suspended the concept of “fairness” which is all well & good but let’s not pretend like Group A is getting a fair deal.

        That's literally the OPPOSITE of what I said, so, no. How in the bloody fuck you got that from my post I have no idea, unless you skimmed it, caught like 5 words, then assumed the rest.

        i’m disagreeing with you bro- AA was never designed with fairness as a principle. maybe to right past wrongs or to bolster diversity but never fairness.

        Mkay, stop, and actually READ what I wrote, mate, and then actually address what I said, not some bullshit you made up in your head about what I said. You can't just say "I'm just disagreeing with you" on one small aspect, when you were attacking everything I said.

        not sure why the article uses the asian/white contrast as the reference point when the truly egregious disparities lie within the asian/black and asian/hispanic rates.

        Isn’t there an implicit missing at random assumption in these calculations?
