that's just "God's chosen people!" with extra words
No it's science: https://www.cambridge.org/core/journals/journal-of-biosocial... . Unless you believe God forced the Europeans to persecute the Ashkenazi Jews in order to create selection pressure for intelligence.
No, why? Apart from the not very plausible explanation with selection pressures in the middle ages, Jewish intelligence is pretty obvious if you look at the data- just as obvious as it's Jewish economic and media power, Jewish influence in Western politics, Jewish contributions to arts and literature, and so on. It really couldn't be more obvious. I think we need to recognise it and find ways to deal with it, from both sides.
