This is part two of a series of articles ordered by 150 IQ Ganzir for $3.50 (he was smart enough to order early before the free market realizes my true value :-)).
In the comment section it was claimed that Jews have a math, verbal, memory and spatial IQ of 113, 109, 96, and 93 respectively. The source for this claim was likely an article I wrote back in 2016. My source was journalist Daniel Seligman who had expressed the test score differences between Jewish & Gentile Caucasians in SD units, which I converted to IQ by assuming an SD of 15 and assuming the Gentile mean was 100.
However Seligman neglected to mention that the groups were equated for socio-economic status (SES). Richard Lynn writes:
These differences were calculated on Jews and Gentiles matched for socioeconomic status. Because Jews have a higher average socioeconomic status than Gentiles, the reported differences are not an accurate measure of the true differences, and there is no way of estimating the Jewish IQ from this study.
Although sociologists commonly control for SES as a way of equating environment, they don’t understand that controlling for SES may also indirectly control for genetic intelligence and thus minimize group differences. This mistake occurs so frequently Jensen coined the term “sociologist’s fallacy” to describe it.
