Ashkenazi Jews have an average IQ of 108-112 compared to a European average of ~100. This shifted mean means they have a much higher percentage of very smart people (~6 times per capita rate of >140iq which is the norm for Nobel prize winners)

This over representation of high IQ is similar to the historical over representation in Nobel prizes for hard sciences.

You can't make conclusions about the number >140 based on a shift of the mean. IQ is scaled so that the general population has a normal distribution. That doesn't necessarily mean some subpopulation has a normal distribution. Even if that was the case, the subpopulation distribution would still have a different standard deviation. (It would partly depend on the level of assortative mating within that population.)

Thanks for expanding on the assumptions I was lazy and just used a ~ to indicate it was approximate.
