Ashkenazi Jews rank one standard deviation above the rest of the world’s white population in IQ. I do not know how they rank against Asians.
The mean IQ for Askenazi is 112.6, with 100 being average white European
Asian IQ depends on country, but it’s 100 to 105ish.
What matters, IMHO, is not the mean, but the number of 140+ IQ people, which are much heavier in Jewish families.
You don’t need many geniuses for a country or a group to get ahead.
I mean, it took one Einstein.
Interestingly, the USA and Israel have pretty similiar bi-modal IQ distributions -— 80 and 120 for an average of 100, so to speak.
This results in a good mix of manual labor and brain power — which is really a very effective mix.
