Polygenic scores as routine research covariates

Genome‑wide polygenic scores for intelligence are now predictive enough that researchers can include them as a measured covariate in biomedical, social‑science and education studies instead of relying solely on psychometric testing. That would let investigators control for inherited cognitive differences from birth and test environmental effects against a genetic baseline. — If widely adopted, this shifts how studies are designed and interpreted (from childhood through health and education policy), and it raises ethical and equity questions about using genetic controls in public‑policy research.
