Race Is Not Biology

During the past two weeks, much outrage has arisen over former Heritage Foundation staffer Jason Richwine's Harvard doctoral dissertation, which speculated that IQ differences between "Hispanic" and "non-Hispanic' populations were genetically rooted. The claims mirrored those of Richard Herrnstein and Charles Murray's scurrilous The Bell Curve: Intelligence and Class Structure in American Life, which made similar claims about the intelligence of blacks. (Murray receives thanks in Richwine's dissertation acknowledgments and wrote recently in National Review Online in defense of Richwine.)

The fury continues. In the past couple days, a group of scholars has circulated a petition excoriating Harvard for approving the dissertation and condoning scientific racism in the process. Their petition situates Richwine within an odious lineage stretching back to the era of eugenics and charges that his work rests on shoddy intellectual foundations. (These scholars are right: the late J. Phillipe Rushton, best known for claiming associations among race, brain size, and penis length, is cited by Richwine.) A group of 1,200 Harvard University students has also put together their own petition. 

But the attacks on Richwine...
