Norway Replicates Education Genetics

A Norwegian genome‑wide association study of education (MoBa, n≈120,527) shows a genome‑wide genetic correlation of about 0.93 with the larger EA4 meta‑analysis, and a high correlation of computed population polygenic scores. However, genetic associations vary when the outcome is partitioned by finishing high school, earning a bachelor’s, or progressing to postgraduate education, indicating heterogeneous genetic architecture across attainment levels. — If education‑related polygenic signals replicate across national cohorts but differ by attainment stage, debates about polygenic score use in policy, education research, and ethical limits (e.g., selection or stratified interventions) need to account for cross‑population robustness and within‑phenotype heterogeneity.
