A 269,867‑person meta‑analysis identified new genetic loci and functional annotations linked to intelligence, enlarging the genetic signal researchers can combine into polygenic scores. That empirical expansion makes genetic prediction of cognitive traits measurably better and more robust across cohorts.
— As polygenic‑score performance improves, debates about educational policy, meritocracy, testing, and fairness will increasingly cite genetic evidence, raising ethical and policy questions about use and misuse.

The article's meta‑analysis sample size (269,867) and reported new genome‑wide significant loci and functional follow‑ups (Savage et al., Nat Genet 2018) exemplify the empirical expansion that strengthens polygenic prediction.
