Race and Intelligence

My colleague Charles Murray, with co-author Richard Herrnstein, wrote the best-selling Bell Curve. It said there was a difference in cognitive intelligence between between blacks and whites, but it didn't matter much because the curves over-lapped.
Now, these definitions are not precise, but consider: Recent Sub-Saharan blacks and Carribean blacks have often been college educated, and are doing quite well, thank you.
And athleticism. NFL coaches believed that blacks couldn't hack it as quarterbacks. Cornerbacks, yes. But a a raft of black QBs have come on the scene (Donovan McNabb, Doug Williams, others.) The job requires split-second timing, tough training regimens, and disciplined thinking. For me that's intelligence.
