If the brightness of European Jews is primarily due to their culture, then we should all seek to be adopted by a Jewish mother. If, on the other hand, it is necessary to be actually born from Jewish parents, then any cultural tips we may get from them may be a bonus, but it is their genes that are crucial.

Some researchers have just had a look at this, and seem to have found a genetic explanation for part of the reason why European Jews are particularly bright.

Dunkel, C. S., Woodley of Menie, M. A., Pallesen, J., & Kirkegaard, E. O. W. (2019, January 24). Polygenic Scores Mediate the Jewish Phenotypic Advantage in Educational Attainment and Cognitive Ability Compared With Catholics and Lutherans. Evolutionary Behavioral Sciences. Advance online publication. http://dx.doi.org/10.1037/ebs0000158

They say:

A newly released multivariate polygenic score for educational attainment, cognitive ability, and self-rated mathematical ability in the Wisconsin Longitudinal Study was examined as a mediator of the group difference between Jews (n 53) and 2 Christian denominations, Catholics (n 2,603) and Lutherans (n 2,027), with respect to educational attainment, IQ, and performance on a similarities measure. It was found that the Jewish performance advantage over both Catholics and Lutherans with respect to all 3 measures was partially and significantly mediated by group differences in the polygenic score. This result is consistent with the prediction that the high average cognitive ability of Jews may have been shaped, in part, by polygenic selection acting on this population over the course of several millennia.

Public Significance Statement

Ashkenazi Jews exhibit high levels of general intelligence. The hypothesis that differences in general intelligence between Jews and Catholics and Lutherans is partially mediated by polygenic scores for educational attainment was tested. The results support the hypothesized partial mediation.

Data were sourced from the Wisconsin Longitudinal Study (WLS). The WLS is a longitudinal study of randomly sampled Wisconsin high school students beginning in 1957; the last wave of data collection was in 2011. The 1957 sample included 10,317 Wisconsin high school seniors. The sample is overwhelmingly of European descent.
9000 of the study participants were genotyped as part of the recent GWAS for intelligence (Lee 2018) and in this study the educational attainment polygenic score was used. It is the stronger predictor. The students were tested on the Henmon-Nelson Test of Mental Ability, a 30-min test consisting of 90 items of increasing difficulty in spatial, verbal, and mathematical ability. The reliability of the test .95; and it correlates .80 to .85 with Wechsler full scale IQ. When subjects were in their 50s they were given 8 items of the Wechsler Similarities test by phone. Intelligence was well tested.

The Jews in this sample are much brighter than the Christians. They had much, much higher educational levels, perhaps a gene-culture synergistic effect, or simply that educational levels measure ability and motivation. Perhaps the 8 point IQ advantage is enough to explain it.

To illustrate the differences between the Jewish and two Christian groups, we combined the two Christian groups and computed Cohen’s d for PGS and IQ. For PGS Cohen’s d 1.33, which is a very large effect size. For IQ, Cohen’s d .57, which is a medium effect size. These group differences are portrayed in Figure 1.

The correlations between the polygenic scores and the intellectual measures are .2 to .3 which is low. Aware that the Jewish sample is small, the authors drew 1000 same sized samples at random from the Christian population to get an estimate of the likelihood of absolutely chance differences between the Jewish and Christian students, and this turns out to be very low, so it is very likely to be a real difference.

The sample of Jewish students is small. However, researchers looking at small samples of ancient genomes argue that DNA is informative even in small samples, because it is a cumulative record of genetic pairings, and is highly informative thereby, but there is still a chance of quirky findings. The authors a well aware of this, and regard their findings as tentative. They certainly do not argue that Jewish cultural transmission is irrelevant, and say that it might support and amplify the genetic factors found by the polygenic scores.

Rare variants associated with lipid storage disorders may indeed confer a heterozygote advantage, which may have augmented the Jewish Group GCA above that which would be predicted by differences in the level of PGS alone, perhaps accounting for the relatively higher frequencies of these disorders in this population. Direct tests of this model still need to be carried out, however.

Dunkel and colleagues have established a tentative link between polygenic scores and Jewish intellectual advantage. This is an important step forwards, and worth testing on larger samples and with better polygenic score data.

    BOGUS FAKE STUDY COMPARES FAKE RACE TO RELIGION.

    This is a bogus study and there are numerous flaws with it.

    Eg. It compares what it calls a race, “Jews”, to a religious group, Christians.

    This invalidates the study because it compares apples to oranges.

    Secondly, “Jews” in Israel have an IQ in the 90’s.

    If they are so intelligent, then why is Israel a failed state, living off of billions of dollars in US aid, and theft (Madoff) instead of becoming rich, when lesser countries surivive on their own?

  2. Questions arise when one considers that “Israel” is said to have an average IQ in the low nineties. Too many variables are involved with the estimate of national IQs and racial IQs. For example after reading a number of articles about this question I notice that such things as representation in certain fields such as medicine, maths and others sciences as well as Nobel prizes awarded is treated as an important indicator yet who doesn’t know the reason for this is blatant and infamously nepotism? Also as with the tests used to measure the intelligences of animals the problem arises again although more subtly, in providing a test tailored to the specific group concerned since their different circumstances entail different outlooks reflecting on how their intelligence might manifest.

    It’s not “smarts” or “IQ” that gives jews an advantage over gentile whites, but is their rabid insistence on cultural and social cohesiveness, insularity and nepotism (but only for themselves) that gives them an “advantage”. This same cultural and social cohesiveness that is prized so highly by jewish interests is denied to gentile whites. Jews, to a man will fight to deny this same cultural and social cohesiveness to gentile whites that they themselves enjoy as it is a major part of the jewish purpose–the destruction of gentile white culture, which IS superior to any jewish cultural or social society. If jews did not possess this power, they would most likely be rag merchants, liquor merchants, or furniture merchants–nothing more. As I have previously stated, jewish success is based on cultural and social cohesiveness and insularity–NOT “smarts” or “IQ”. Once enough jews get into a position of power in the work world or education systems, they will hire and promote their own, bypassing more qualified gentile white candidates.
    Jews have latched on to cultural cohesiveness and nepotism, as it serves their purpose exceedingly well.
    At the same time, jews pushed the concept of racial “equality”, (but only for gentile whites), backing it up with “civil-rights” and “equal accommodation” laws which are enforced by governments—in the United States, at the point of bayonets–but only against whites. These “civil-rights” laws are used as a “battering ram” against gentile whites to diffuse and fragment any semblance of gentile white solidarity and cohesiveness that may arise.
    A great reckoning dealing with the jews is coming. As gentile whites become more marginalized, the accusation of being tagged as “racist” or a “holocaust denier” is rapidly losing its “sting”.
    Increasingly, jews are more wary of being “called out” and recognized as “jews”. One can call a jew a shyster, shylock, bankster, criminal or ne-er-do-well, and it will roll off his back like water off a duck, BUT call a jew a “jew” and he will recoil in horror, having been “found out”.

    A sample size of 53 is ridiculous, particularly of Jews in Wisconsin who can scarcely be said to be any more representative of Jews in general or even Ashkenazi Jews than Africans in Britain are representative of Africans in general. Their chart of Jewish IQ is heavily smoothed to the point of being fraudulent. With a sample size of 53 it should be very jagged.

    They say: “the high average cognitive ability of Jews may have been shaped, in part, by polygenic selection acting on this population over the course of several millennia”, which shows remarkable ignorance of history. Ashkenazim have only existed as a distinct group for about 800 years, and Jews in general for 2800 years at the very most, and non-Ashkenazi Jews have an average IQ of less than 95, more like 90.

  8. The Jews in this sample are much brighter than the Christians

    Lawrence Auster, a Jew who converted to Christianity, wrote that American Christians were ‘the Jews’ best friends in the world’. Given the strength of Christian Zionism, few would disagree with him. In which case, it isn’t particularly bright of Jews to engineer the mass immigration which will reduce their best friends to a powerless minority. For example, Stephen Steinlight worried himself sick that non-whites would be less servile:

    ‘Will a country in which enormous demographic and cultural change, fueled by unceasing large-scale non-European immigration, remain one in which Jewish life will continue to flourish as nowhere else in the history of the Diaspora? In an America in which people of color form the plurality, as has already happened in California, most with little or no historical experience with or knowledge of Jews, will Jewish sensitivities continue to enjoy extraordinarily high levels of deference and will Jewish interests continue to receive special protection?’

    Jews may well have a higher IQ but they are sorely lacking in common sense.

    It’s called “infiltration”. You see, jews start small, inserting themselves into desired positions by hiding their “jewishness”. Once their numbers are large enough, it is “too late”. Jewish cultural and social cohesiveness and nepotism takes over. You see, “multiculturalism” and “diversity” are only for gentiles. Jews have always reserved the right to exclude themselves from such destructive practices.
    A good video on this phenomenon is “Der Ewige Jude” which is available with English subtitles. This video shows jewish infiltration into gentile society, with its disastrous consequences.
    “Hiding their jewishness” is one of the oldest “tricks” that they use to complete their infiltration.

    It would be interesting to see a scatterplot (say IQ vs. PGS). I am surprised the Christian IQ plot is more jagged than the Jewish IQ plot given the data size disparities. I assume they used the same smoothing for both?

    Even if that plot is oversmoothed I think calling that fraudulent is a stretch. Do you think it materially changes the point being conveyed?

    several millennia

    A number of people have jumped on this. I think there is a good argument for the strongest Jewish IQ selection to have occurred over more recent periods, but I don’t think that makes their statement false or provide cause to dismiss the overall results.

    Jews in general for 2800 years at the very most

    This gives numbers like 3200-3500 years: https://en.wikipedia.org/wiki/Jewish_history
    Pretty much what I would term “several millennia.”

    As a “tentative link”, very well,

    Agreed. Sample size is too small and specific to justify sweeping conclusions about “Jews.” Especially without specifying smaller groups (here probably Ashkenazi): https://www.myjewishlearning.com/article/sephardic-ashkenazic-mizrahi-jews-jewish-ethnic-diversity/

    it is completely overwhelmed by the within-group evidence for genetic IQ from sample sizes orders of magnitude larger.

    I think you are missing the point here. This study supports the assertion that Jewish-Christian differences in IQ are partially genetic-based. Within group studies don’t speak (much) to that question. As some people tirelessly remind us when debating the causes of group differences in IQ.

  17. EH says:
    @res

    The smoothing gives the impression that they had vastly more data than they really did. Only a few of the points on their plotted line are based on actual data, the rest interpolated and would likely not replicate. Even NLSY or AFQT data sets with hundreds of thousands of subjects look much more lumpy when plotted honestly than the n=53 sample here.

    The Jewish history article prior to 586BC depends entirely on their claims. Going by the evidence of archaeology and the neighboring peoples, there was probably no Abraham or Moses, definitely no David or Solomon, no First Temple as described, and even by their own account, prior to the Babylonian conquest no Jewish people as such, but a confederation of separate tribes of various backgrounds with considerably differing and contending religious practices. There were various Canaanite peoples, there were Semitic peoples, and these, in part, became the Jews as a more-or-less unified people during the Babylonian captivity. But the Jews’ account of their history up to that point is disputed. DNA evidence with big sample sizes from modern Israel and their neighbors compared with ancient samples from the area will, I think, put the final nail in the coffin of the claims of the antiquity of Jewish origins as a distinct people.

    As for the within-group vs. between group evidence: first, the evidence of average Ashkenazi IQ is extraordinarily weak, with all sample sizes being tiny and unrepresentative and the fraction of them achieving high scores e.g. on NMSQT/PSAT having collapsed in past three decades; and second, the “within-group” variation for the large, supposedly homogeneous White gentile population actually is many different groups that were, and to a considerable extent still effectively are, different lineages that could be compared to show that IQ variations between groups are largely genetic. In fact, they would be better for the purpose than Black-White comparisons since the same genetic variants will be causing the IQ differences, which doesn’t seem to be the case with the B-W difference.

    Thanks for elaborating. I don’t think that really refutes anything I said (e.g. ancient Jewish history is controversial, “several millennia” is not outright incorrect given current knowledge), but you make clear the well thought out details of your position.

    We really need the raw data to judge how representative their smoothed plot is. Even with histograms the dependence on bin size can be troublesome. Do you disagree that the shape of the smoothed Jewish IQ curve is likely to be in the ballpark of reality for the group sampled from?

    Good point about looking for genetic influence on intra-white group differences. Presumably small differences will be harder to detect than large differences though.

    Regarding evidence of Ashkenazi IQ, the best evidence for me is just noting their representation in high achievement professions overall and at successively higher levels of performance.
    The collapse of test scores is a puzzle to me.

    I wonder if Emil et al. have looked at which particular variants account for the bulk of the group difference in PGS. That seems like an interesting question to try to answer.

  22. Actually, Askenazi Jews are more likely to have bred with non-Jews (witness the pale complexions, occasionally paired with blue eyes and light brown or even blond hair) than Sephardic Jews–something on which the Sephardic Jews pride themselves. A friend of mine had parents so lineage-conscious they referred to his then-girlfriend as “The Ashkenazi,” despite the fact that she had an olive complexion and jet-black hair. (He later moved in with a red-haired lapsed Lutheran practicing Wiccan, but that’s another story.)

    So what’s really going on here is what any horse-or dog-breeder can tell you: pure breeds may have the most cachet, but they also have exaggerated characteristics. A good mutt or grade horse often has the most even temperament.

    This is not a subject about which I know particularly, but I have my doubts about such genetic investigations and what you say is also what I think. Jews are not a race at all as Shlomo Sand showed in his book. There are Jews from all genetic backgrounds. Jews in Europe are mostly Berbers from North Africa, Turks who converted quite late to Judaism and Slavs who problably converted even later to Judaism, and possibly many other european groups.

    One possibility that Jews became more intelligent would be that intelligent Jews reproduced more effectively than intelligent people in other groups and at the same time prevented stupid Jews from having offspring becase otherwise while there might be more intelligent Jews, there would also be more “stupid” Jews in the Jewish population than “stupid” people in other populations. If this happened, it would be the case that the sons of well educated rabbis who also became rabbis had a better chance to have children than other Jews. But is it necessarily true that a more educated person (who basically studied religious texts) is also a more intelligent person? Is it the case that rabbis were really more intelligent than other parts of the Jewish population? If that was the case, it doesn’t seem to be the case anymore. Are there many rabbis who have interesting intellectual works? I have never heard that this is the case (it could be the case that children of rabbis who are not rabbis anymore have interesting works).

    It’s true that many extremely well educated Catholic priesters didn’t have children, but the reality was that Priesters were often homosexual while the others had children anyway. Was it then the case that children of priesters didn’t have a good education and didn’t marry? Protestant priesters had children. Other people in Europe who succeeded socially had children. So, where is the Jewish advantage? We have to make many doubtful assumptions to believe that Jews are more intelligent.

    If I had told the Jews I knew that they were supposed to be more intelligent than other people, they would have laughed because they knew that that was not true. Of course, this is not a proof of anything. I believe that there are bright people anywhere and that it’s a question of chance who and what they are.

    Just a few decades ago we could easily have said that the Chinese were a complete desaster, but now they are showing that they can compete with the West.

    We know from larger sample sizes Ashkenazim don’t have a standard deviation gain on whites. In fact, the two are rather close. The authors admit the sample size is small, yet still say that Jews are more intelligent. We just had Audacious Epigone give different estimates with GSS and Nyborg. They ranged from 108-112.

    Ashkenazi are simply a subset (Ethnicity) of White Europe, with a possible admixture of some Asiatic genes. It has been argued that Jews went through possibly one or more “bottlenecks” in which the most intelligent were able to survive and reproduce. Not unlike most people groups, but with a tighter core, and more in-group preference. It may go back (See Behar studies) to four female founders, which account for the mtDNA of most Ashkenazi (Haplogroup K subsets).

    It’s arguable that of Europe, both Finland and Anglo-Saxons had, at least the past, high IQs for the same reasons. If you get to know any Episcopalians, liberal and annoying as they may be, they are clearly the most intelligent people you will meet, along with Ashkenazi (save perhaps Japanese). Even now, most Episcopalians (American Anglicans), that are multi-generation (meaning not late joiners), are of Anglo-Saxon, Anglo-Norman or high Celtic ancestry (Scottish). Because of Admixture, I’ve found Americans of Scottish ancestry to be very intelligent–even the (gasp) Scots-Irish, the latter having a bit more of a temper.

    American/European Jews are almost entirely Ashkenazi. But in Israel, Ashkenazi Jews are only about half of the Jews, the other half are Mizrahi Jews who are very very similar to Arabs (in appearance, culture and IQ). Culturally, Israel today resembles more a middle eastern country than a European country. Mizrahi Jews have pulled it way down.

    Thanks for your polite reply Res, I should try to be more so myself.

    “Do you disagree that the shape of the smoothed Jewish IQ curve is likely to be in the ballpark of reality for the group sampled from?”

    I highly doubt that the curve for several thousand 14-17 year olds randomly selected from the Jewish population of Israel or even New York would resemble the curve of the 53 Wisconsin Jews of 1957 more than it would resemble a curve for contemporaneous Wisconsin White gentiles. In the case of Israel, I’d expect the mean would be about -.33 to -0.7 s.d compared to today’s White Wisconsin gentile high school students, and in the case of New York I’d expect the Jewish average to be about +0.3 to +0.6 compared to Wisconsin, but the high-fertility lower-IQ ultra-Orthodox who seldom attend public schools might bring the N.Y Jewish average down to a 0 – +0.4 gap.

    There might be a bimodal curve for Jews as shown in the article, but I’d expect it to disappear with a bigger sample, with the s.d. about the same size as Wisconsin gentiles 14.5 – 15.5. If the different Jewish subgroups were treated separately, I’d expect a slightly lower s.d. than gentiles for non-ultra-Orthodox considered alone (14- 14.5) and a substantially lower s.d. for ultra-Orthodox (12.5 – 13.5).

    Of course, that’s all just my guess, but I doubt there will be a good study of Jewish IQ anytime soon.

    I suspect the reason that there hasn’t ever been any good IQ study with an n in the thousands from a reasonably representative sample of even the non-ultra-Orthodox is that they really don’t want to know the truth and, even more, they don’t want gentiles to know the truth. Even the idea that there is a truth is probably projecting my goyishe kopf thinking onto them.

    By yiddishe kopf thinking, if they test smarter they’ll envied and suspected by the goyim of using their intelligence to take unfair advantage (this is the default Jewish belief, almost an article of faith). If by some chance Jews test equal – or, G-d forbid, even lower IQ – than the goyim, that would just prove to this group with an unshakeable faith in their own superiority that the tests are no good anyway, and the goyim would once again start kvetching that maybe Jewish relative wealth isn’t entirely due to merit. So what’s the upside for the Jews? Bupkis. I don’t see that reflexive attitude changing any time soon, maybe not within the next several thousand years. 😉

    It can be hard to be polite when talking about such controversial topics. I try, but don’t always succeed. I also try to limit my impoliteness to those who both initiate and persist in the same. I am a big fan of the “Tit for Tat with forgiveness” strategy. Both in a theoretical and practical sense.

    I generally agree with you, but one more charitable reason I would offer is Jews not wanting a detailed IQ study to cause divisiveness between Ashkenazi, Sephardi, and Mizrahi. I have my criticisms of Israel, but do admire what they have achieved and can understand how important it is to not let the country become divided over something like that.

    Good point about maintaining cohesion among the various Jewish sub-groups, not to mention the Ethiopian Jews, but there isn’t much fellow-feeling for them from the other groups; the Falasha have recently been protesting in the streets of Tel Aviv.

    As for politeness, my natural inclination is much like Mencken’s: “every normal man must be tempted, at times, to spit on his hands, hoist the black flag, and begin slitting throats”, so I have to make extra effort.

    Good Mencken quote. A problem of mine is that I can flip dramatically between politeness and hoisting the black flag (e.g. see some of my interactions with trolls here, though I do try to keep things under control with some self imposed rules) and I think that can be off-putting to people and make them unsure what to expect from me. I think it mostly comes from some experience with bullying when younger and my concluding that the best response to a bully is a (literal or metaphorical) punch in the face. And I process the people trying to shut down debate on these topics (and the ones who write what I perceive as bogus papers, like this one) as bullies.

    Your effort is appreciated. You have made many interesting comments here (and IIRC also in your blog which you link occasionally) so it is good to be able to have constructive discussions.

    So this PGS is mainstream enough now to come pre-computed in the datatset. Wow.

    They come pre-computed for a few datasets now. I expect in the future, these kinds of datasets will provide 100s of pre-computed PGSs.

    If you have full DNA data in the future would it be possible to work with impute.me to look at ALL of their PGS? It seems like that would be a good way to look at genetic group differences en masse. They have open sourced their code (they use R) at https://github.com/lassefolkersen/impute-me

    Sure, but we don’t need impute.me/DNA.land etc. to compute these, as it is trivially easy with access to the array data files using plink/PRSice.

    P.S. I assume you saw this paper showing how at least some GWAS loci translate across races?

    Yes, we follow these PGS across populations studies very closely. See also the FAQ. http://emilkirkegaard.dk/en/?p=7680

    The bimodal distribution results from a large sex difference in this dataset (5 IQ). We are doing a meta-analysis of sex difference in IQ among Jews because apparently it is quite marked across the 5 datasets we looked at so far. Stay tuned.

    Thanks! I did not know about PRSice. Does it include the breadth of pre-loaded PGS that impute.me has? That was not obvious to me from their home page.

    Did you ever fix your 1000 genomes SQL server? https://emilkirkegaard.dk/en/?p=6255
    I am looking for a freely available dataset (other ideas gladly welcomed) to experiment with tools like this, and that seemed like one of the best candidates.

    I saw your FAQ a couple of days ago. Very interesting.

    P.S. For others interested in this topic, this summer course mentioned at the PRSice home page looks interesting: https://www1.kcl.ac.uk/prospectus/shortcourses/index/name/polygenicriskscoreanalysis2019/alpha/month/day/header_search/polygenic+risk

    Thinking about this some more, has anyone done PCA or a correlational analysis of (hundreds of) PGS results on a large population (say the UKBB)? It would be interesting to see if genetic load pops out as a general factor and might help cast some light on which traits are under balanced vs. directional selection. It would also be interesting to look at between group PGS differences in the same way. Mapping the group PGS differences to differing group selective pressures might be informative.

    No, it’s a scoring tool.

    Did you ever fix your 1000 genomes SQL server? https://emilkirkegaard.dk/en/?p=6255

    No. Use the public 1000 genomes files to compute the frequencies using standard binf tools. I still have the precomputed results somewhere, should probably upload them to mega or something for ease of reuse by others.

    That is an interesting point, and way too accurate.
    If you look at the work over the decades to control the governments and media by the Zionists, or “Jews,” what stands out strongly is how much is done in the shadows, or simply in secret.
    Recent history of 9/11 and the misadventures in the middle east stands out.

    If “push comes to shove” the jews will align themselves with the moslems, as islam has sprung from the jewish “root”. You see, islam is an arabicized form of judaism, always has been, and always will be.
    The “animosity” that jews show for moslems is part of the “plan”, and is false on its face.
    The only real animosity that moslems show for jews is from the black “Nation of Islam” in which Louis Farrakhan correctly states that blacks are being “used” as “useful idiots” by the jews to further their own aims. Jews actually have disdain for blacks. Witness the Ethiopian jews who are some of the first jews around, who are still denied Israeli citizenship, despite “the law of return” (which is supposed to apply to ALL jews).
