interesting discussion. but regarding 99%, I know of no environmental manipulation which can explain that much of individual differences. it's not just about reliability, it's also about explaining all the variance - two different things.

i see - so you're talking about gene x environment interactions. it's true this isn't accounted for in the analysis. but i find it hard to believe that environmental effects of any sort could explain 99% of the variance that we see here, an

i have trouble seeing how these comments apply to the content of the post - parenting influences are largely controlled (as you seem to indicate) and I don't see how these heritability estimates could reflect something unrelated to executiv

to preempt common criticisms: 1) 99% is not unbelievably high, given that they used factor analysis to improve the reliability of the measurements 2) this doesn't preclude a) environmental influences that interact with genetic profiles nor

You think that liPFC is involved in gain? An alternative is cue specification, which is consistent not only with the work purportedly showing a gain-like function in liPFC, but also with other work suggesting a role for liPFC in episodic r
