You've obviously thought very hard about all this. But you do know that blacks commit a lot more crime (~ 10x) everywhere, not just America? The answer has everything to do with race. Most people on HN belong to another ~ 10x crime group. We're males. I personally don't mind my tendencies that much. But to say they're cultural? Stop pretending it's the sixties. The blank slate is dead. Science killed it.

It's very plausible, and indeed pretty much undeniable, that male behaviour is different to female behaviour (eg higher aggression) for biological reasons. Males and females have been under vastly different selection pressures for millions of years, so it makes sense that the survival/reproduction strategy for males should be different to that for females.

However, it's only been <100,000 years since the various ancestral lineages of modern humans split off from one another, and only in the last few thousand years that life in Europe or China has been significantly different to life in Africa (apart from the climate). Huge differences in behaviour between the different lineages are very unlikely.
