...But pride has always been haunted by fear that public acknowledge of Jewish achievement could fuel the perception of "Jewish domination" of institutions. And any characterization of Jews in biological terms smacks of Nazi pseudoscience about "the Jewish race." A team of scientists from the University of Utah recently strode into this minefield with their article "Natural History of Ashkenazi Intelligence," which was published online in the Journal of Biosocial Science a year ago, and was soon publicized in The New York Times, The Economist, and on the cover of New Yorkmagazine.

The Utah researchers Gregory Cochran, Jason Hardy, and Henry Harpending (henceforth CH&H) proposed that Ashkenazi Jews have a genetic advantage in intelligence, and that the advantage arose from natural selection for success in middleman occupations (moneylending, selling, and estate management) during the first millennium of their existence in northern Europe, from about 800 C.E. to 1600 C.E. Since rapid selection of a single trait often brings along deleterious byproducts, this evolutionary history also bequeathed the genetic diseases known to be common among Ashkenazim, such as Tay-Sachs and Gaucher's.

The CH&H study quickly became a target of harsh denunciation and morbid fascination. It raises two questions. How good is the evidence for this audacious hypothesis? And what, if any, are the political and moral implications? (Registration required)
