Point completely missed by DeepLeftAnalysis🔸 . Sure, you can mathematically calculate averages of different groups. That doesn’t make those averages meaningful, or a good description of those groups, or a good guide for public policy. The newest science tells us that racial-ethnic groupings don’t line up well with DNA and that race is a poor causal model of human evolution given millennia of admixture (not to mention the most recent work on environmentally induced epigenetic change). My article acknowledges mild inherited differences between populations due to different selection pressures over time but argues that the predictive power of these differences on success is much weaker than the kinds of environmental factors you can tweak with good policy.
