The article is pretty interesting and I didn't read the whole thing. The correlations are positive but not 1, sometimes less than 0.5. So it shows genes are positively correlated, but very different than saying it's an exclusive factor? So the problem with this is that even if something is correlated at 10% (for arguments sake), it can have predictive power. But that doesn't mean it can become the sole basis. Thats the cognitive jump most folks are incapable of and these discussions often lead to very wrong outcomes. Indeed this bias has led to many horrific examples of discrimination. Also the heritability seems to be put at 0.5, not a sure thing? So it obviously can be heritable, but that doesn't rule out that it is only heritable and no other avenues for it exist?
