I know your stance on saying the truth without regard to dumbing it down for audiences that shouldn't read it, but I think this is one point where you should explain more. I conjecture that a nontrivial amount of people reading that line also have the same confusion I had.

To be specific, I'm arguing that IQ between ethnic groups in the US is likely much less than 50% determined by genes. Finding genes correlated with IQ doesn't imply genes play a direct causal role, and there are very strong explanations that don't involve genes... (read more)
