      Maybe the debate should focus on the scientific common ground that is beyond any serious dispute: there are mean phenotypic IQ differences across human groups, regardless of their origin. They exist in every multi-group society. What should we do about them?

      We don't yet have good data on the polygenic IQ scores across populations, whether they show structural invariance, and how they relate to ancestry informative markers. In 5-10 years, we will. Til then, genetic influences on group differences are very hard to measure.

      Tep. Heritability is specific to population, context, and cohort. Height has a heritability of about 80% within a cohort, but height can increase dramatically across generations with improved nutrition and medicine (e.g. in China now). Same might have been happening with IQ.
