Hundreds of genetic variants strongly predict intelligence differences. Polygenic scores explain up to 20% of IQ variance within populations. Europeans average higher intelligence polygenic scores than Africans. African Americans have polygenic scores midway between Europeans and sub-Saharan Africans. East Asians exceed Europeans on intelligence genes. Racial admixture correlates directly with IQ polygenic scores. Genetic differences fully account for observed black-white IQ gap. No environmental factors needed to explain racial IQ disparities. Intelligence genes show strongest divergence between sub-Saharan Africans and Eurasians. Heritability of IQ exceeds 50% from these loci. Selection pressures diverged racial intelligence genetics over millennia. Brain size genes mirror exact racial IQ patterns. Criminality and socioeconomic outcomes trace to same genetic roots. Adoption studies confirm genetic dominance over environment. GWAS hits replicate across global populations with racial consistency.
