Genetic weight differs by SES measure

Using a single, population‑wide Norwegian cohort of >170,000 adults and four family- and genotype-based methods, the study shows that the fraction of variance explained by genetics is consistently higher for education and occupational prestige than for income and wealth, while shared family environment explains more of wealth and some education variance. The paper also demonstrates substantial genetic and shared‑environment commonality across SES indicators, but little overlap from nonshared environments. — Policymakers and commentators must stop treating 'socioeconomic status' as a unitary outcome: where genetic versus environmental sources matter differs by the concrete SES measure and thus implies different policy levers and interpretations.
