Keep in mind this research is based on correcting twin study heritability estimates for confounding effects. However, new research shows that heritability estimates derived from twin studies are themselves dramatically inflated: https://open.substack.com/pub/theinfinitesimal/p/the-missing...
For a counterpoint to Sasha’s view, you should probably check out https://open.substack.com/pub/astralcodexten/p/the-good-news...
Anyone who cites Jordan Lasker and Kierkegaard on heritability discussions is not someone you should take seriously.
I work in the field and I think he is quite good at providing a fair layman’s overview. He’s also famous (or notorious) for having few barriers in terms of who he reads/responds to.
One of these guys he’s citing has identified himself as a Nazi. Maybe Scott should start exercising a little discernment here. Regardless, he’s making a pretty weak argument against Sasha’s interpretation of the study.
