Jews have, more successfully than all other people, and somewhat by accident of selective upward redistribution of reproduction, transferred feminine cognitive ability (language and perception) to the males, and male cognitive ability(agency) to females, at the cost of higher rates of homosexuality and mental illness, and lower rates of creativity. (yes, really). This ‘blending’ of traits combines the best of both worlds.
The mistake is to think that they are necessarily more exceptional than our most exceptional whites (Anglicans). Anglicans produce higher average IQ. But the Jews produce more outliers because of a wider standard deviation in their distributions. And they practice nepotism on a scale that westerners can’t imagine – the same way women advance their children.
There is quite a bit of work studying these things now. So it’s getting much easier to explain the differences. I try to explain Jewish behavior by saying “all Jews are female” and while that’s an exaggeration it does explain the entirety of Jewish success: adopting the female cognitive, collective, and reproductive strategy.
This is probably the most explanatory argument available today.
