@SashaGusevPosts @kalle_leppala @_twolfram https://t.co/xEbHrHa1a1 Interestingly the older NTFD IQ studies find a negative cultural transmission too. They dismiss it as unlikely, however ascertainment can't really bias this method as argued by Young ? http

The samples used for that plot were not very large and they're not relevant either, but I wanted to picture something. The finding that a model of phenotypic assortment beats a social homogamy model has replicated. Sources: https://t.co/NJCPKUK0La https:
@PGKroeger "Heritability estimates of general intelligence in adulthood generally range from 75 to 85%, with all heritability due to additive genetic influences, while genetic dominance and shared environmental factors are absent, or too small to be detect

@aaronclauset Importantly, it may be the case that estimates of shared family influences are themselves overestimated; more complicated twin modeling suggests that these estimates for cognitive traits in reality reflect genetic influences from assortative
@itsbirdemic @AlpacaDeGuerra @Airmanareiks Perhaps! But extended twin & family studies which account for gene-environment correlation, dominance & assortative mating report even *higher* heritability estimates for adult IQ & *no* shared environ
@robkhenderson This is just the breeder's equation. The value in (3) is wrong, it should be the additive (narrow) heritability, not broad heritability. This value is about 0.5, not 0.8. This is probably the best family study we currently have. https://t.

With regards to advanced modeling of heritability of intelligence, these are the two most important papers to replicate and expand upon. 1) Extended family design for examining other variance components. 2) Measurement model. https://t.co/Fm88meBvxi htt
