This leads to another third rail issue. Nature vs. nurture of race vs. culture. I can claim no expertise, but I think there is some ratio with variability among individuals. Related of course to the innate vs. culture issues of masculine and feminine traits. Not completely binary but unfortunately not well enough understood.

I am well-traveled throughout Asia, and I have noticed things "Asian" in countries with cultural differences from each other which are also observable. I have no explanation or theory.
