Heritability of traits is not always directly genetic.

Heritability of traits is not always directly genetic.
- hntrader 6y agoCorrect. I was asking what the basis is for your confidence that it positively isn't substantially genetic. We know that intelligence is highly heritable, which leaves a few possible explanations, genetics being one of them (along with prenatal nutrition, prenatal lead exposure, etc). If you're going to claim that genetics is only a small part of the reason that it's heritable, then that has its own burden of proof that needs to be met.
