re: stem – there is one biological fact that seems to be universal: males have more variability than females. That would mean that the average might be same or not, but there is more males with very low abilities and with very high abilities. So, when you are talking about best CS in the world, there will be way more males even if we resolve all social and family differences. At the same time, there are more men who are the most stupid and winning Darwin awards every year.
