The average IQ of the ethnicity you refer to is 115 when they are of European descent. This is a full standard deviation above Western average.
Most likely, this is a result of centuries of persecution, as well as, well, inbreeding. The children of people who didn't marry inside this ethnicity simply became white.
Doctors have long noted that Ashkenazi Jews are uniquely susceptible to various genetic diseases. For example, they’re about a hundred times more likely to have Gaucher’s Disease, a hundred times more likely to get Tay-Sachs Disease, ten times more likely to have torsion dystonia, et cetera. Genetic diseases are so common in this population that the are official recommendation is that all Ashkenazi Jewish couples get screened for genetic disease before marriage. I’m Ashkenazi Jewish, I got screened, and I turn out to be a carrier for Riley-Day syndrome – three hundred times as common in Ashkenazi Jews as in anyone else.
The tradeoff is often that one copy of a gene substantially raises IQ, but two copies completely screws you up:
Gaucher’s disease, one of the Ashkenazi genetic diseases, appears to increase IQ. CHH obtained a list of all of the Gaucher’s patients in Israel. They were about 15 times more likely than the Israeli average to be in high-IQ occupations like scientist or engineer; CHH calculate the probability that this is a coincidence to be 4×10^(-19).
Torsion dystonia, another Ashkenazi genetic disease, shows a similar pattern. CHH find ten reports in the literature where doctors comment on unusual levels of intelligence in their torsion dystonia patients. Eldridge, Harlan, Cooper, and Riklan tested 14 torsion dystonia patients and found an average IQ of 121; another similar study found an average of 117. Torsion dystonia is pretty horrendous, but sufferers will at least get the consolation prize of being really, really smart.

The flip side of the coin are debilitating genetic diseases:

Does that explain how 26 Jewish scientists were part of the Manhattan Project, including key names?
C'mon.
