Intelligence and fertility are known as complex traits. The fact they are complex doesn't mean they are not acted on by genetics: they are just highly polygenic. Almost all attempts to measure the heritability of intelligence have reached estimates between 50 and 80%.

Did you really read my post?

Anyway, I often hear that claim of 50-80% but I can never find the publications backing up that claim. Can you list some, please?
