Could you cite those for my own edification?
That doesn't seem to be the case, though.

In 1900 in London Jews took a disproportionate number of academic prizes and scholarships in spite of their poverty (Russell and Lewis, 1900). In the 1920s a survey of IQ scores in three London schools (Hughes, 1928) with mixed Jewish and non-Jewish student bodies showed that Jewish students had higher IQs than their schoolmates in each of three school, one prosperous, one poor, and one very poor. The differences between Jews and non-Jews were all slightly less than one standard deviation. The students at the poorest Jewish school in London had IQ scores equal to the overall city mean of non-Jewish children.
The Hughes study is important because it contradicts a widely cited misrepresentation by Kamin (Kamin, 1974) of a paper by Henry Goddard (Goddard, 1917). Goddard gave IQ tests to people suspected of being retarded, and he found that the tests identified retarded Jews as well as retarded people of other groups. Kamin reported, instead, that Jews had low IQs, and this erroneous report was picked up by many authors including Stephen Jay Gould, who used it as evidence of the unreliability of the tests (Seligman, 1992).
