From The Atlantic:
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 are missing something far more insidious than neo-eugenic claims about innately inferior intelligence between races. The backlash against Richwine and Murray, after all, gives some indication that their views are widely considered beyond the respectable pale in the post- Bell Curve era. Richwine and Murray are really extreme branches of a core assumption that is much more pervasive and dangerous because it isn't necessarily racist on the surface: the belief in biological “races.” This first assumption is required to get to claims like Richwine's, which argue that between Race A and Race B, differences exist (in “intelligence” or whatever else) that are grounded in the biological characteristics of the races themselves. Public outcry always greets the second Richwine-Murray-esque claim. But the first assumption required to reach it is more common and based on as shaky an intellectual foundation, even as it continues to escape equal scorn. Even so, the critique of biologically innate race is hardly new. In 1972, the Harvard biologist Richard Lewontin famously observed more genetic variation within populations than between them, undercutting the case for fixed and timeless genetic boundaries that demarcated “races.”
