AllI have to say is "The Bell Curve"
It explains it all.
"The Bell Curve" has nothing to do with this. Something changed in the 1960s that made black culture worse than it had been in the previous hundred years. I agree with the author that what changed was the introduction of unearned welfare entitlements.
"All I have to say is 'The Bell Curve'"
Oh boy, you are just looking for trouble, aren't you? Whatever differences in average IQ, if any, that exist between various racial groups, I don't think the effect comes anywhere near explaining what we are seeing. I teach at a university and I can tell you that the difference between female and male black students is like night and day. Some of my best students have been black females - sharp, respectful and very engaged in learning. On the other hand the majority of black males have serious attitude problems - I get the impression from them that I am at best an inconvenience and they really have much more important things to be doing than listening to what I have to teach; they seldom ask questions or even make eye contact. Most of them probably won't make it to graduation and many of them don't even make it through the first 4 weeks of my class. There is much more going on here than just some small differences in average IQ between various racial groups. The thing same could be said about the dearth of caucasian students in engineering and computer science courses - again, the differences claimed in the Bell Curve are not significant enough to account for this in my opinion.
