From page 63 of IQ and Wealth of Nations (thanks to Amazon):

"The IQ of 94 in Israel is higher than the IQs in the remainder of this group of nations. The explanation for this is that Israel is an ethnically diverse nation with about equal numbers of Western (European) and Eastern (Asian) Jews. Western Jews have an IQ 12 points higher than Easters Jews (Lieblich, Ninio, and Kuglemass, 1972; Zeidner, 1987). The IQ of Eastern Jews in Israel is aproximately 88 and is closely simlar to the IQs of the neighboring South Asian populations like Turkey (90), Lebanon (86), Iraq (87), and Iran (84). The IQ of Western Jews in Israel is aproximately 100, which is about the same as that of other Northern and Western European populations, although Jews in the United States and Britain have substantially higher IQs averaging 110 or even 115 (Hernstein and Murray 1994; MacDonald, 1994)...."

Three cheers for the Anglosphere's salubrious affect on Jewish intelligence!
