IQ and the sciences
According to many studies, Ashkenazi Jews have the highest average intelligence of any ethnic group as measured by IQ, leading East Asians, who also perform highly in IQ. Many of these studies indicate that the primary Ashkenazi advantage is in verbal reasoning and the East Asian advantage in spatial (mathematical) reasoning.
Ashkenazi jews also perform highly in correlated areas. For example, while only 0.25% of the world population is Jewish, Jewish scientists make up 28% of Nobel prize winners in physics, chemistry, medicine, and economics, and have accounted for more than half of world chess champions.[10] In the U.S., Ashkenazi Jews represent 2% of the population, but have won 40% of the US Nobel Prizes in science, and 25% of the ACM Turing Awards (the Nobel-equivalant in computer science). A significant decline in the number of Nobel prizes awarded to Europeans and a corresponding increase in the number of prizes awarded to US citizens occurred at the same time as Nazi persecutions of Jews during the 1930s and the Holocaust during the 1940s.[11]
Whether this difference in IQ and achievement is due entirely to a culture of study and vocational training (environment), or partially to a difference in genetic variables, is presently unknown and controversial. (See Race and intelligence)
