The other interesting thing was the meaning of "diversity." For the students organizing the boycott, it pretty clearly was shorthand for "hiring more black and female professors, admitting more black and female students." This suggests the following question:
"Suppose the school is considering hiring a new faculty member. You discover that he has expressed the opinion that intelligence is to a considerable degree genetic, and that the distribution of intelligence probably varies significantly with race and gender. Is this fact an argument for or against hiring him?"
If the real objective is intellectual diversity, the answer is obviously "for." The opinion is a defensible one that is almost never expressed by faculty members, at least at my school, so a new hire willing to defend it would make the faculty more intellectually diverse. But I would give high odds that most of the students boycotting in favor of "diversity" would give the opposite answer.
