Didn't read it; didn't need to. I was on and around a multi-college campus through the 80s and 90s. My fields were computer science and business. The lessons of TBC were painfully obvious, even before they brought in a basketball program to that campus. Afterwards, the academic quality dropped like a rock.
Sowell also had a book back then about various college majors and the accompanying IQ/SAT scores. Big uproar among the commies.
It was bad enough back then. Wouldn't want to be there now.
shudder. You and I would probably be killed.
