Serum urate among Ashkenazim

I am, alas, up to my eyeballs in study ideas with little patience or ability to carry them out. Here’s one such idea.

Ashkenazi Jews have high intelligence (IQ ~110) but their achievement is in excess of this. There is also some evidence for high psychological ‘intensity’ among Ashkenazim,  and for high levels of serum urate. In the study of Erdberg, Boner, van Dyk and Carel (1991; http://www.karger.com/Article/Abstract/186728), Ashenazi patients with insulin-dependent diabetes mellitus and controls had significantly (p < 0.05) higher levels of serum urate than Sephardics. This suggests to me that Ashkenazim have high serum urate levels, which may explain their achievement and intensity (serum urate is a psychostimulant and correlates with high academic achievement when controlling for g). What do you think?

  1. Reader says :

    The real secret to Ashkenazi success is not IQ (which is only part of the equation) but their relentless ethnic networking. Ashkenazis have high IQs and are extremely ethnocentric, unlike high IQ whites who tend not to be so ethnocentric. Lack of ethnocentrism is the Achilles heel of white people.

  2. elijahlarmstrong says :

    That’s true, but high serum urate of Ashkenazim could help to explain the psychological intensity I noted (and possibly, in an indirect manner, high ethnocentrism. serum urate ––> high intensity ––> ethnocentrism?).

  3. Arman says :

    How does their achievement exceed what their IQ would predict?

    • elijahlarmstrong says :

      Check out Richard Lynn’s “The Chosen People.”

      TL;DR: Suppose that the average IQ of winners of the Nobel Prize in physics is IQ 145. Suppose that Jews are overrepresented 10-fold amongst persons with IQs of 145, as they would be if their IQ is 110 (SD = 15). If Jews are 2 percent of the population, their expected representation amongst Nobel winners is 16 percent. If the average IQ is 160, Jews’ expected representation is 40 percent. So Jews may not in fact be overrepresented when correcting for IQ, at least amongst physics Nobelists.

      • Arman says :

        “If jews are 2 percent of the population, their expected representation amongst Nobel winners is 16 percent”

        Given what you said with the 145 IQ model + a general population IQ of 100, their expected representation would be 13%.

        Now, to test the real numbers:

        Given what you said, modifying the US Jewish IQ to the 110.4 estimated by Lynn in the aforementioned book, their population proportion to 2.1%, and the US non-Jewish population’s IQ to 96.3(based off Lynn & Vanhanen(2012)’s US IQ estimate of 97.5 + a factoring out of the Jewish IQ), and a 145 IQ model, their expected representation would be approximately 28%.

        With a 160 IQ model, the expected representation would be approximately 48%.

        Not very far from what is actually the case.

        “So Jews may not in fact be overrepresented when correcting for IQ, at least among physics Nobelists.”

        Concluding this, how can you say that their achievement is in excess of their IQ?

    They are overrepresented relative to intelligence in some fields, such as finance and entertainment. As far as academia goes, I admit that I am wrong.
