It displays a common misunderstanding - that if genetic variants are associated with a trait, then they must be revealing some proximal *biological mechanism*. This is not the case.

Of course, for some traits and some variants, there is a direct molecular mechanism underlying the association. (Think of eye colour, for example).

But for complex traits (and especially for social outcomes), the effects of genetic differences may also be mediated through environmental or cultural mechanisms

For educational attainment, we know this is the case. As described here, for example: The nature of nurture: Effects of parental genotypes

...which showed effects on educational attainment of parental genotypes that were NOT transmitted to the offspring (i.e., mediated by "nurture")

So, the idea that polygenic scores for social traits somehow give you a pure look at innate *biological mechanisms* is simply wrong.

There will always be a complex interplay of innate predispositions, family environment and societal and cultural factors, often acting in amplifying loops...

The evolution of reading clearly demonstrates that nature and nurture are intimately linked.

More than most traits, educational attainment is strongly influenced by the "Matthew effect": For to every one who has will more be given, and he will have abundance; but from him who has not, even what he has will be taken away. — Matthew 25:29

try explaining this to shallow behavioural 'scientists', it's a tour de force. comparable to implementing prediction models with black box processes. the same ignorant mistakes get made over and over again. you'd think we'd gotten rid of John Watson by now.
