Is There a Gene for Left and Right?

The maximum amount of the variability of pluric attitudes that could be explained on the base of this is 40%, which first of all leaves a lot more to be explained by social and cultural effects. And even that 40% I think it's certainly not that there's a gene for left and right. So when you say we can trace some of this to genetics, you're not saying people are born in liberal. It's just a weird, but people are very, very, very hypersensitive about that kind of essentializing.
