Common Genes Partly Predict Income

A genome‑wide study of 668,288 people of European ancestry found 162 loci linked to a common 'Income Factor' and built a polygenic index that explains about 1–5% of differences in income. The results suggest genetic variation systematically correlates with socio‑economic position and with health gradients tied to that position, but effect sizes are small and sociopolitical interpretation requires care. — This reframes debates about inequality and the health gradient by adding robust, quantitative genetic evidence that can inform (and complicate) policy conversations about causation, intervention, and the risks of genetic determinism.
