he Chosen People: A study of Jewish Intelligence and Achievement is the most recent work of Richard Lynn dealing with group differences in IQ and their ramifications. As in all of his previous work over the past decade, he substantiates his arguments with huge quantities of empirical data. He advances his positions dispassionately and lets the facts speak for themselves, which they do in impressive, nearly irrefutable fashion. In his previous books he examined racial and ethnic differences in IQ for many groups.The Chosen People is a case study of one distinct group that has shown remarkably similar patterns of achievement in a wide variety of settings.

Professor Lynn begins by pointing out the extraordinary success of Jews in almost every field. In the 19th century the restrictions that had prevented most Jews from advanced nonreligious study began to be lifted in most of Western Europe, and by mid-century, “people began to observe that Jews were outstandingly successful, and began to speculate that this was attributable to their intellect.” (Unless otherwise noted, all quotations are from Professor Lynn.)

At that time the great bulk of Jews were still living in Eastern Europe, but owing to pogroms beginning around 1880, Jews began migrating to Western Europe and especially to the United States. They formed part of the massive immigration to the US in the period from 1880 to 1924.

Prof. Lynn writes:

They arrived as penniless refugees unable to speak the languages of their new countries; they were the “huddled masses” from the most backward region of Europe. Yet by the middle decades of the 20th century, the children and grandchildren of these immigrants were doing far better than their Gentile hosts on all indices of socioeconomic status and earnings and outperforming them by several orders of magnitude in obtaining elite academic distinction . . . .

The development of IQ tests confirmed the impression that Jews were unusually intelligent, and Professor Lynn’s extensive review of the literature indicates that Jews in the US have an average IQ of 110 compared to 100 for other Europeans. This would help account for their outstanding performance in a variety of fields. Though Jews are only about 0.2 percent of the world population, half the world’s chess grandmasters, for example, and 16 percent of Nobel Prize winners for science have been Jews. For Professor Lynn, the purpose of his book “is to document and explain such achievements.” It would be a mistake to think that these are the accomplishments of all Jews, however, as they are mainly the achievements of Ashkenazi Jews, the Jews of Eastern Europe.
