“Even at the top colleges, professors may be disallowed from failing minority students anyway. (I know an adjunct at Harvard who was told this expressly.)”
I went to Stanford in the 70’s. The hispanics I knew were quite capable students and not much different from anyone else. I only knew 1 black and he was a geeky engineering student who was pretty good too and pretty much “an oreo”.
The students who were not good were the athletes. I knew a caucasian basketball player who dropped out, a caucasian swimmer who dropped out, and a caucasian runner and two caucasian football players who did graduate but really had to work at it.
There were a lot of blacks on campus but they tended to self segregate so it was hard to get to know them.
You do realize the ‘70s was 40 years ago?
In the early nineties they had already begun the “social promotion” policy of sending blacks to the next level of schools (above that where their qualifications would merit); as a result many of the black students were segregated into the “remedial building” taking high school classes that would have been required of white APPLICANTS. There were a good number of African students mixed with the general population, and they were serious about school/good students. Hispanics were very much assimilated with the general student body as well.
