Genetic Proxies Replace IQ Tests

Updated: 2018.07.05 7Y ago 2 sources
Genome‑wide polygenic scores (PGS) for intelligence and education now explain a measurable share of IQ variance and can be computed from birth, allowing researchers to use DNA‑based proxies for intelligence where formal testing is impractical. That shifts how many studies could measure and control for cognitive ability and opens debate over early‑life stratification, consent, and misuse. — If genetic proxies become a standard research covariate or screening tool, it will reshape education policy, medical research, and ethical norms about using genetic data to predict cognitive traits.

By identifying additional genetic variants and functional pathways associated with intelligence, the paper strengthens the technical basis for substituting or supplementing traditional cognitive testing with genetic proxies in research or policy settings, with implications for hiring, education, or insurance uses.
