A big new and important study came out today on the heritability of intelligence and other traits.
Even better, Alexander Young, one of the study’s co-authors, wrote a blog post that, though I wouldn’t say is totally accessible to laypeople, is a helluva’ lot more understandable than the actual study itself.
And, best of all, Kirabo Jackson, one of the top researchers out there for making studies accessible, shared these tweets about the study:
This is by far the most credible approach to date on the nature/nurture question (in my humble opinion). The blog is well worth a read for social scientists!! https://t.co/gaiIx31lfS

Using much more detailed genetic data than in the past, new study finds that heritability of educational attainment is only about 17%. Much lower than twin or sibling studies would suggest. My sense is that this may even be an upper bound.

That is exactly my interpretation of this emerging lit & consistent with findings from the largest GWAS study to date: https://t.co/s5Q4gmHM1U (11%-13%). One reason it is likely higher in the one you mention is that environmental variability is quite low in egalitarian Iceland.
