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 podcast centers on a Nature paper (Akbari et al.) making broad claims about selection on cognitive traits drawn from large genome‑wide association study (GWAS) signals — precisely the dynamic captured by the idea that big GWAS results are driving stronger public and scientific attention to IQ genetics.

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.

The article (Robert Plomin, Scientific American) summarizes twin, adoption and genome‑wide association study (GWAS) evidence showing substantial heritability (~50%) and notes that recent large GWAS identify loci that together explain a small but growing fraction (~5%) of intelligence variance — directly matching the claim that big GWAS are elevating the role of genetics in public discussions of IQ.
