>>12223248Obviously 'how much' something is genetic depends on the environment. For example, take 2 individuals with different genetics, given the exact same circumstances, their intelligence would be 100% genetic. On the other hand, if their circumstances are extremely different, that could be a large factor in intelligence differences. The same is true of the closeness of their genetics. If identical twins experience different circumstances, their intelligence differences will be 100% environmental. So there is no flat number which explains how much a certain characteristic depends on nature as opposed to nurture. It depends on the set of genes in question as well as the environment in question. Therefore, it makes more sense to ask about how genetic a certain trait is at a given time in history (and even better in a certain place), or conditional on a certain set of circumstances. That being said, this study attempts to quantify the effects of genetics on intelligence using twin studies and finds 80% heritability.

Ashkenazi Jewish people undoubtedly lost historical dice rolls and they're doing better than anyone now. Lots of groups have suffered terribly, but only the low IQ ones are still griping about it, because they're the only ones who haven't been able to turn their countries and communities around since escaping colonialism.
