"Six of the nine traits, including educational attainment, showed greater genetic variance among offspring, which is inconsistent with stable assortative mating over many generations."
Ok... maybe I'm not understanding. I don't think educational attainment is inconsistent with assortative mating. In fact, I think it is consistent with the theory as it applies to passing on traits. The theory only really applies to traits with high genetic influence (for passing on). Educational attainment is not genetic. Even if it's partially associated with IQ (not really), IQ is not all that strong of a heretical trait.
> Early twin studies of adult individuals have found a heritability of IQ between 57% and 73%, with some recent studies showing heritability for IQ as high as 80%. IQ goes from being weakly correlated with genetics for children, to being strongly correlated with genetics for late teens and adults.
