Here is a recent article from the Duke Chronicle on the continuing “problem” of having enough faculty diversity.
The really funny stuff is at the end. One professor had the nerve to suggest that part of the problem might be that few black youths are interested in academic careers. For that, he was rebuked by another professor who said there was no evidence for the “acting white” theory and pronounced herself “offended.”
It won’t do anything to reduce her level of offendedness, but there is some good evidence that black students, even from affluent families, don’t apply themselves very seriously to their studies. The late John Ogbu pursued that line of inquiry. You can read about his career and scholarship here.
