Why is the IQ of Ashkenazi Jews so high?
Ashkenazi Jews are smart. Shockingly brilliant, in general. Impressively greater in brain power than the bulk of the human population. How did they get that way?
Ashkenazi Jews, aka Ashkenazim, are the descendants of Jews originally from medieval Germany, and later, from throughout Eastern Europe. Approximately 80% of the Jews in the world today are Ashkenazim; the remainder are primarily Sephardic.
Researchers who study the Ashkenazim agree that the children of Abraham are on top of the IQ chart. Steven Pinker – who lectured on “Jews, Genes, and Intelligence” in 2007 - says “their average IQ has been measured at 108-115.” Richard Lynn, author of “The Intelligence of American Jews” in 2004, says it is “only” a half-standard higher: 107.5. Henry Harpending, Jason Hardy, and Gregory Cochran, University of Utah authors of the 2005 research report, “Natural History of Ashkenazi Intelligence,” state that their subjects, “score .75 to 1.0 standard deviations above the general European average, corresponding to an IQ of 112-115.” Charles Murray, in his 2007 essay “Jewish Genius,” says “their mean is somewhere in the range of 107-115, with 110 being a plausible compromise.”
A Jewish average IQ of 115 is 8 points higher than the generally accepted IQ of their closest rivals—Northeast Asians—and approximately 40% higher than the global average IQ of 79.1 calculated by Richard Lynn and Tatu Vanhanen in IQ and Global Inequity.
Plus, contemplate this astounding tidbit: Ashkenazi “visual-spatial” IQ scores are only mediocre; in one study their median in this category was a below-average 98. They surmount this liability by logging astronomic figures in “verbal IQ”, which includes verbal reasoning, comprehension, working memory and mathematical skill; a 1958 survey of yeshiva students discovered a median verbal IQ of 125.6.
I’m not asserting Ashkenazi cognitive specialness because I’m philo-semitic, or a Zionist, or pro-Israeli. I’m pointing it out because it is irrefutably true. People who can’t comprehend the easily understood data verifying high Ashkenazi IQ may not simply be anti-semitic; they must also be crippled in the math/logic zone of their inferior parietal cortex, with subsequent IQ in the ~85 range.
In the 19th century, Mark Twain noted that:
[The Jews] are peculiarly and conspicuously the world’s intellectual aristocracy… [Jewish] contributions to the world’s list of great names in literature, science, art, music, finance, medicine, and abstruse learning are.. way out of proportion to the weakness of his numbers. He has made a marvelous fight in this world… and has done it with his hands tied behind him.
Twain’s observation is not dated. Ashkenazi Jews have continued to mentally out-compete other demographics since his statement, often suffering horrendous consequences for their toil. Here is a brief list of Ashkenazi accomplishments in the last 90 years.
Nobel Prizes: Since 1950, 29% of the awards have gone to Ashkenazim, even though they represent only 0.25% of humanity. Ashkenazi achievement in this arena is 117 times greater than their population.
Hungary in the 1930s: Ashkenazim were 6% of the population, but they comprised 55.7% of physicians, 49.2% of attorneys, 30.4% of engineers, and 59.4% of bank officers; plus, they owned 49.4% of the metallurgy industry, 41.6% of machine manufacturing, 72.8% of clothing manufacturing, and, as housing owners, they received 45.1% of Budapest rental income. Jews were similarly successful in nearby nations, like Poland and Germany.
USA (today): Ashkenazi Jews comprise 2.2% of the USA population, but they represent 30% of faculty at elite colleges, 21% of Ivy League students, 25% of the Turing Award winners, 23% of the wealthiest Americans, and 38% of the Oscar-winning film directors.
Israel: In 1922, this swamp and desert land was inhabited by a impoverished population of 752,000. Today there are 7,746,000 residents, with an Ashkenazi majority that have elevated it into a high-tech entrepreneurial nation with the highest per capita income in the region.

Ashkenazi Jewish intelligence, often referred to as the "Jewish genius",[1][2][3][4] is a subject that explores why Ashkenazi Jews tend to have a higher intelligence than all other ethnic groups and excel disproportionately in many fields, and has been an occasional subject of scientific controversy.
The average IQ score of Ashkenazi Jews has been calculated to be from a range of 110–115, significantly higher than any other ethnic group in the world.[5][6][7]

Ashkenazi Jews rank smartest in world
Studies show descendants of Jews from Medieval Germany, throughout Europe have IQ 20% higher than global average
Is it possible for your ancestry, religious affiliation, or nationality to determine your intellect?
According to a study performed by Cambridge University called, "From Chance to Choice: Genetic and Justice," Ashkenazi Jews have a median IQ of 117.
That’s 10 points higher than the “accepted” IQ of their biggest competition, Northeast Asia, and 20% higher than the global average.
