NHAI is quite firm on the Ashkenazi IQ advantage: Ashkenazi Jews have the highest average IQ of any ethnic group for which there are reliable data. They score 0.75 to 1.0 standard deviations above the general European average, corresponding to an IQ of 112-115... although a recent review concludes that the advantage is slightly less-only half a standard deviation (Cochran et al. 2006, 3) The "recent review" they mention conveys a very different impression from that forceful assertion (Lynn 2004). It has often been asserted that Jews have a higher average level of intelligence than non- Jewish whites of European origin... Despite these assertions, the purported high IQ of the Jews has never been systematically reviewed... Despite the widespread consensus on the high Jewish verbal ability, not all studies have shown that Jews have a higher verbal IQ than gentiles. Furthermore, virtually all the existing studies are unsatisfactory because the samples have been unrepresentative, very small or for other reasons (pgs. 201-202)... There is only one study of the intelligence of American Jews in the last century which appears to be representative and had a reasonable sample size. This is Backman's (1972) analysis... The mean IQs of the Jew in relation to gentile white means of 100 and standard deviations of 15 were as follows: verbal knowledge (described as "a general factor, but primarily a measure of general information".. .)--107.8, English language 99.5; mathematics-109.7; visual reasoning ("a measure of reasoning with visual forms")-91.3; perceptual speed and accuracy-102.2; memory (short term recall of verbal symbols)-95.1 (pg. 203). Lynn compares this result with an analysis of vocabulary scores using national survey data broken down by categories including Jewish and non-Jewish white. This he translates into a verbal ability score (not full-scale IQ) of 107.5 for American Jews, compared to 100.0 for gentiles (pg. 204). Other estimates come in higher or lower. MacDonald (1994, 190)~whose three volume series is dedicated to demonstrating a Jewish evolutionary strategy of promoting their own reproductive success at the expense of gentiles-comes in at the top, with a general IQ around 117 and a verbal IQ around 125. Hughes (1928, 90), cited in NHAI, made a large study of London school children under the supervision of Cyril Burt. He found Jews scoring about 10 points higher than gentiles, regardless of economic well-being. But Hughes also refers to previous studies of Jewish immigrants to the U.S.: "four of them find that Jews are not more intelligent than the non-Jewish American population, and four of them find that they are." Patai and Wing (1975, 146-149) review studies, most of which give Jews higher IQ, but a few of which do not. That same year, Dershowitz and Frankel (1975, 127) compiled other findings. The average verbal IQ (WISC) from two studies of American Jews was 8.4 point higher than Italian-Americans, 7.5 points higher than Irish-Americans, and 3.1 points lower than WASP-Americans. For performance IQ, Jews came out lower all around, 2.7, 2.6, and 9.2 points below, respectively. For full scale IQ, Jews beat Italians and Irish both by 3.2 points, and lost to WASPs by 6.8 points. Another study by the authors of 185 Israeli Jewish children found a much lower score than for the Americans, with an average IQ of 96.13. Taking all the information together, it is fair to say that most, though not all, studies give Ashkenazi descendants a higher IQ than non-Jewish whites. How much? Take your pick Reply With Quote
