A few years ago I was looking into affirmative action admissions in med schools and unfortunately found that it was alive and well there too. I’d bet Peter Allen didn’t get into other med schools because he was a white male even though in aggregate males score better than females on MCAT. The fact that he got into Pitt suggests his MCAT score was pretty good.
A couple years ago I dated a girl who was in med school. She told me that some med schools’ admissions processes favor admitting practicing homosexuals as some sort of “minority.” Please note, I never verified this, but it unfortunately sounds like the sort of lunacy you’d expect from some in academia these days.
