Even if it weren't hereditary (although I believe that it's well accepted and uncontroversial that it is), it's still pretty clear that it's innate. Even if intelligence is randomly distributed, I've never heard anybody suggest that intelligence isn't something you're just "born with" whether you got it from your parents or just got really lucky.

Well you just heard me say it. Your thinking capacity is limited and inherited but just like physical muscle devlopment, you can develop it. Women basically have to work out 10x men to have similar muscle development (hormones) but they can develop it. Similarly,you don't just grow muscle because your ancestors had a lot of muscle,you still have to work out. All that I have read about intelligence leads me to believe that while hereditary ceiling differences exist for certain "mental muscles", it is something you develop starting from early stages of life.
