More troublingly, I'm not seeing any indication that they investigators accounted for a Scarr-Rowe interaction. Rookie mistake. That interaction should've been the *first* thing they looked for. Otherwise, as Eric Turkheimer has argued, they might be better off not estimating "heritability" at all <http://psycnet.apa.org/record/2011-18633-009>. --David Epstein da...@neverdave.com

Household income is incredibly highly skewed. Assuming they obliviously used a linear coefficient to obtain the 7% figure, it is probably a severe under-estimate of the true size of the effect.

A masive study using genomic info as a predictor of educational achievement showed that genes accounted for only about 11% of the difference in years of education. The Scientist Mag has a layperson friendly description of the study published in the journal "Nature Genetics". See: https://www.the-scientist.com/news-opinion/genes-explain-about-11-percent-of-differences-in-years-of-education-64552 [4] There are links in the article to additional sources. So, I guess this pretty much undermines "g" or single factor theories of intelligence (assuming intelligence drives educational achievement as certain theorists assert). In addition, household income accounts for only 7% of the variance in the differences which some might consider a unexpected low amount. I guess this all goes to show that your genetic ancestry (sorry Galton) nor wealth/poverty are the most important factors in academic acheivemnt, like getting a Ph.D. or other advanced degree. Now, I just hope the results are replicable. ;-) -Mike Palij New York University m...@nyu.edu [5] P.S.
