An astute commenter asks why we should oppose race-based decision making, if there is real correlational information to be had from ethnicity. I offer two reasons: 1. this country has a bad record on race, and striving towards a race-blind society is worth some small sacrifices, 2. the evidence for genetic group differences is not conclusive and should be treated with great caution.(Boldface mine.)
For political and quasi-Marxist (oppressed minority = oppressed class) reasons, US anti-discrimination policy is formulated in terms of groups. Differences in group outcomes are attributed to discrimination. The finding of outcome-affecting genetic differences (if they exist) between groups would be mitigated were social policy focused on treating individuals fairly.
