Scholars have struggled for decades to explain why Jews have succeeded extravagantly in modern science. A variety of controversial theories—from such intellects as C. P. Snow, Norbert Wiener, and Nathaniel Weyl—have been promoted. Snow hypothesized an evolved genetic predisposition to scientific success. Wiener suggested that the breeding habits of Jews sustained hereditary qualities conducive for learning. Economist and eugenicist Weyl attributed Jewish intellectual eminence to "seventeen centuries of breeding for scholars."
Rejecting the idea that Jews have done well in science because of uniquely Jewish traits, Jewish brains, and Jewish habits of mind, historian of science Noah J. Efron approaches the Jewish affinity for science through the geographic and cultural circumstances of Jews who were compelled to settle in new worlds in the early twentieth century.
