Three‑SNP Score Still Tracks Population IQ

Across 46 population samples, a 2013 three‑SNP education polygenic score remains highly correlated with modern, much larger education and fluid‑intelligence polygenic scores and with estimated population IQ. The author reports concrete correlation numbers (e.g., 0.939 with EA3) and compares multiple recent GWAS including a new Norwegian cohort and a Pan‑UK Biobank fluid‑intelligence score. — If a tiny early genetic signal remains aligned with modern polygenic results and with population IQ estimates, it strengthens the empirical footing of public debates about genetic contributions to cognitive and educational outcomes — raising policy, ethical and communication stakes.
