Jewish people are overrepresented in fields as diverse as politics, science, the wealthiest americans, art, etc. compared to their population size. Jewish people are only 2% of Americans but they make up about 10% of senators, about 25% of nobel prize winners and fields medal winners, 20% of the wealthiest 400 americans, etc.
I can think of a few potential causes.
Jews have a higher IQ, around 115 on average for verbal and mathematical IQ, but a little lower for spatial. But there is no real correlation between IQ and wealth or life success, and the correlation between IQ and income is pretty weak. I think there is about an extra $500-1000 in average income per year per IQ point, but only about $50 in extra net wealth per IQ point (since higher income people can spend themselves into debt too). So the higher IQ could explain some of the success in fields like science, but it doesn’t explain why Jews are more successful at politics or why more wealthy people are Jewish.
There is a culture that encourages success, that could play a role. Second generation immigrants from all over the world are likely more successful than the average person, they seem to be overrepresented in fields like science, engineering or medicine (especially Asian immigrants). About 14% of doctors are Jewish (again vs 2% of the population). So a culture that emphasizes success (especially in the face of persecution, where success can function as a buffer to keep you safe from abuse) could explain part of why Jewish people make up far more than 2% of high prestige careers than their population.
Another part could be that since Jewish people have such a history of persecution, maybe there is a cultural attitude that you have to succeed to prove yourself and people like you. But I don’t know if you can really apply that to all Jews. I’ve known various Jews, many don’t really identify with that label of Jewish anymore than I identify with the nation my great grandparents came from. So I don’t know how valuable that would be.
There is the fact that maybe it is a self fulfilling prophecy. There are more white males who are 6’2" as CEOs than you would expect based on their population distribution. It isn’t that tall white males are necessarily more competent, just that people have an unconscious judgement that they are competent so they give them more power and authority. Perhaps Jewish people have the same thing, people have an unspoken assumption they are good at XYZ, so they are more likely to get hired at XYZ. But things like that don’t explain why 20% of the wealthiest americans are Jewish since they likely had to be entrepreneurs or the children of entrepreneurs to get to that level of success.
So fundamentally, why do Jewish people succeed at such a diverse group of things? A higher IQ could make them better at fields like science or academia, but it doesn’t explain their higher than average success in art or getting wealthy. There could be cultural pressures, but Asian americans also have a lot of cultural pressures to succeed and they aren’t 10% of senators. There could be a cultural attitude of success, but a lot of Jews don’t really think about their own Jewishness or what it means to their relationship to the world. And Jewish people have been persecuted just as much (if not alot more) than they’ve been viewed as exceptional. Jews were overrepresented in law, business, politics, etc in Germany before the holocaust too, hardly a society that would view Jews as individuals people ‘want’ in positions of power (the way people today might view a tall white man as someone they unconsciously want to be in charge). So even in cultures where people put up roadblocks for Jewish success, Jews still are disproportionately successful in a wide range of fields. Except sports.
