Large verbal/performance IQ differences have been found within Jewish populations. Levinson (1958) studied a representative sample of yeshiva students and found an average Verbal IQ of 125.6, an average Performance IQ of 105.3, and an average Full Scale IQ of 117.86, although he suggests that there may have been a ceiling effect for some students on the verbal portion. Whereas in the general population there was a correlation of 0.77 between Verbal and Performance IQs, among Jewish children it was only 0.31. Finally, Levinson (1960b) found that a sample of Jewish boys (age 10-13) with an average Verbal IQ of 117 had a Performance IQ of 98, while Irish and Italian samples matched for Full Scale IQ had Verbal/Performance differences of only approximately 5 points (approximately 110-105). Levinson (1959) provides evidence that the Verbal/Performance difference for Jewish children increases from pre-school to young adulthood. When children were matched on the basis of full-scale Wechsler IQ, pre-school children showed a small (3-point) difference between Performance and Verbal IQ, while elementary school-age and college student subjects showed a difference of approximately 20 points.
âTaken together, the data suggest a mean IQ in the 117 range for Ashkenazi Jewish children, with a Verbal IQ in the range of 125 and a Performance IQ in the average range. These results, if correct, would indicate a difference of almost two standard deviations from the Caucasian mean in Verbal IQ exactly the type of intellectual ability that has been the focus of Jewish education and eugenic practices. While precise numerical estimates remain somewhat doubtful, there can be no doubt about the general superiority of the Ashkenazi Jewish children on measures of verbal intelligence (see also Patai & Patai 1989, 149).
