Using administrative records for 170,000 Norwegians aged 35–45, researchers decomposed genetic and environmental influences on education, occupational prestige, income, and wealth. They found genetic variation explains more of educational attainment and occupational prestige, while shared family environment explains more of education and wealth, with little commonality from non‑shared environment across the four. Estimates also differed by heritability method, even in the same population.
— This shows policies and arguments about 'merit' and inequality must reckon with which SES dimension is under discussion and avoid treating heritability as a single, context‑free number.

The paper decomposes PGS prediction into within‑ and between‑family components and finds SES largely accounts for the between‑family effects on cognitive and educational traits, directly echoing the idea that social environment interacts with genetic signals differently across outcomes.

The article documents changing heritability of educational attainment across time and regions (Fig. 1) and argues SES is constituted differently across contexts; this directly corresponds to the existing idea that measured SES heritability depends on which SES indicator and timeframe are used.
