most research estimates it at 50/50.See overview of research Wow, that is quite the interesting PDF.
By age 26 when you have a fully formed adult brain, your intelligence is 88% genetic. But at age 5, only 22% of intelligence is genetic. I can understand why people are supportive of early education programs like Head Start that target disadvantaged youths. It must be horribly confusing to find that almost all the benefits of early nurture vanish by adulthood.
Anti-social behavior is about 40% tied to genetics. Makes you wonder how often rehabilitation is even possible. Perhaps felons should be sterilized
Right wing authoritarianism, which I think was just a bizarre thing to test for, is 50%-64% genetic. I wonder if the same can be said for Liberalism? Perhaps reeducation camps just aren't feasible
