The claim that race is a myth because of the overall genetic similarity of human beings was transparently silly, but people bought it because they liked the way it sounded. It’s hard to know whether the genome researchers who promoted it believed it or not, but it certainly helped them avoid funding problems. Here’s evidence on one point that’s been hard to work into the accepted dogma of the absolute unity of mankind: Race plays role in drugs’ effectiveness. The story was inspired by a recent finding that blacks who took the AIDSVAX vaccine had almost 80% fewer HIV infections than blacks who took the placebo, while whites had less than 4% protection from infection. The issue might seem a minor one for any consideration of racial differences, and it is, but the extremism of accepted antiracialist positions gives it importance.
