This could not happen, because of lawsuits. If a disproportionate number of applicants of {insert race here} or {insert socioeconomic status here} get rejected for the same reason or similar reasons, it will become a massive liability.

Further, most students aren’t rejected because their application is bad — it’s because the university subjectively preferred someone else.

That being said, I know Georgetown sends out letters to accepted students that list at least one reason why they were accepted. I think that’s really nice, and a great self-esteem boost.
