I seem to also remember that Ashkenazi Jews had the highest IQs of any group on the planet.
That may explain the stereotype that Jews are so miserable. Smart people aren’t the happiest people around.
>>I have read that Ashkenazi Jews have a much higher frequency of above genius level IQ than any other group of people on earth.<<
They do. That’s a given. It’s been known for decades. They are .2 percent of the world’s population, but 20 percent of Nobel laureates. (Something like that.)
“I have read that Ashkenazi Jews have a much higher frequency of above genius level IQ than any other group of people on earth.”
That seems true, except for a blind spot related to politics. ;-)
My brother-in-law is mixed German/French/English lineage, but I always thought he looks rather stereotypical Jewish. The Jews apparently think so too - when he vacationed in Israel, everyone insisted on speaking Hebrew to him.
