Jew IQ

Vox Day recently disputed the notion that ZOG is a result of high Jewish IQ. In so doing, he's drawing swords with the likes of Gregory Cochran, Charles Murray, and Stephen Pinker. To atrociously mix metaphors, that prices me way out of the cognitive market, so I won't comment on the merits or demerits of Vox's assertion.

What I will do is take a look at what light the GSS can shed on the question. The following graph shows mean IQ estimates by selected demographics computed by converting the mean wordsum score among native-born non-Hispanic whites to 100 and assuming a standard deviation of 15 (N = 8,896):


To avoid language fluency issues, results are restricted to respondents who were born in the US. For contemporary relevance, all data is from the year 2000 onward.

One big issue with using wordsum as an IQ proxy--the two positively correlate at .71--is that because the vocabulary quiz only contains 10 questions, there is a converted IQ ceiling of 130, exactly two standard deviations above the white mean. Respondents who ace it all get recorded as having IQs of 130. While 4.2% of gentile whites score 10 out of 10, 12.1% of Jews do. In statistical terms, the first Pearson coefficient of skewness for gentile whites is -.20. For Jews it is -.66.

This artificially pulls the mean of high scoring group down. If the artificial ceiling was removed, the Jewish mean would likely increase by a couple of points.

The problem theoretically exists on the left side of the distribution, too, but it's of far lesser consequence because a wordsum score of zero converts to an IQ of 46.2. The number of respondents with IQs under 50 who are administered the survey must be negligible. It's unlikely they'd even be capable of completing it.

Another big issue is that estimating IQ in this way focuses entirely on verbal IQ at the expense of visuo-spatial IQ. Asians in the US tend to have modestly higher IQs than whites on account of a small visuo-spatial advantage over whites while whites enjoy a smaller advantage over Asians on verbal measures of IQ. Hispanics and American Indians also do better on visuo-spatial side of IQ tests than on the verbal side. Blacks and Jews, in contrast, do better on verbal than on the visuo-spatial.

Consequently, this method presumably modestly overstates black and Jewish IQ while modestly understating Asian, Hispanic, and American Indian IQ.

The GSS doesn't inquire about whether or not Jews are Ashkenazi, but it does ask about race. Among Jews who self-identify racially as white and so who are presumably Ashkenazi, mean IQ is 108.9. Among non-white Jews, mean IQ is 96.5.

Finally, Jewishness is inquired about in a religious rather than an ethnic context in the GSS. Some portion of ethnic Jews identify as having no religion and thus are not included in the Jewish results but are instead included in the Gentile white results. The Jewish-Gentile gap reported here is thus likely modestly understated as a result.

Parenthetically, here are the ten wordsum items. If you're reading this blog there's a good chance you'd score a perfect 10 out of 10. Forget the 2% being the cognitive elite--we outperform the vast majority of (((them))). We are the true cognitive elite!

GSS variables used: WORDSUM, BORN(1), RELIG(1-2,4-13)(3), RACECEN1(1)(2)(3)(4-10), HISPANIC(1)(2-50), PARTYID(0-1)(2-4)(5-6)(7), CLASS, YEAR(2000-2016)

It's so brutally stark that you can regenerate every harsh truth the American moral empire has been trying to obfuscate since the '60s with a ten question vocabulary test. If that's too crude the Wonderlic takes 10 minutes. IQ is the penicillin level wonder science of sociology and psychology. We restrict its prescription to universities and the military.

It's pretty obvious that most jews quietly self-explain success with superior inborn intelligence while simultaneously denying reality otherwise. It's the natural crude self-serving hypocrisy of unchecked power.

szopen said...

R. Lynn seemed to think that Ashkenazi Jews were IQ 110; VD went for 107.

The Jews from GSS data, however, would be not 100% Ashkenazis, right? VD argued that there is high intermarriage between gentiles and Jews. Assuming the GSS overstates IQ (per your points), and using guesstimates of 50% pure and 50% intermarried, the data would jibe well with assumption of "pure" Ashkenazis with 110, and "mixed" Ashkenazis with 105-106.

Sid said...

Three thoughts...

1. An Ashkenazi average IQ around 107-110 seems very plausible. I think Richard Lynn is on the money when he says that Jews combine high intelligence with networking. Jews tend to be extraverted, ethnocentric, and have the knack for business you see in many Mediterranean peoples. It's not farfetched to assume that they get into high IQ professions and help direct their fellow high IQ coethnics to lucrative opportunities.

Why should this be a surprise? Everyone does this. Northern Europeans have made an effort to be more inclusive and meritocratic, but even we operate on networking.

2. VoxDay points out that Israel doesn't have a particularly impressive economy or society.

I agree with him, but I think it's because Israelis were committed to a number of political, economic and cultural goals that limited their flourishing.

For one, the original Zionists envisioned Jews becoming a blood-and-soil, agricultural people. They intended to not only give Jews a homeland, but also to match 19th century nationalist ideals.

There's a lot to praise about these ideals, but they're subpar for training a cognitive elite.

Israel has had to focus its talent on maintaining its national security. You may hate Israeli foreign policy (I'm ambivalent about it), but they fought in four conventional wars within 25 years of their founding and have since had to administer occupied territories and deal with non-conventional security challenges since then. Israel has been a Sparta for decades, and that has limited their overall potential.

In recent years, however, Israel has been enjoying relative stability in the region, and their military expertise is creating a thriving tech sector. I would say that, yes, Ashkenazi Israelis probably do have an IQ around 107-110 and have finally found an avenue for realizing their cognitive potential. (Sephardic and Mizrahi Jews, however, usually don't enjoy particularly high IQ scores).

3. This thought is based less on fact and observation, and more on emotional perception, so this will be my weakest point.

Jews generally come across as less intelligent today than they did in the first half of the 20th century. Even before I took the red pill, I found the claim that Jews produced minds like Einstein and John von Neumann because they "valued education" to be specious. Sorry, but there's no way you can just "educate" yourself into being as smart as they and their generation of theoretical physicists were.

When the Nazis took power and kicked Jews out of physics departments, people lamented that those departments were empty.

Personally, I could believe that Jews in that era had an average IQ of 115, which today seems a little too high.

Jews I've talked to today (some of which are close friends) come across as Koreans do: quite clever but not necessarily scary smart. (Korean IQ is probably around 105-107, which is close to that of Jews.)

Of course, this is all just my individual perception and I definitely don't want anyone to think I'm asserting Jews have declined in intelligence on a generic level or something.

My guess is that the best and brightest Jews moved into theoretical physics in the early 20th century, and one way or another came to dominate the field. A point Steve Sailer made a few years ago is that the best and brightest British dominated biology and economics (if R.A. Fisher and Keynes weren't scary smart, who was?), while Germans dominated rocket science*. As such, I bet there is a networking effect in the sciences, where certain ethnicities cluster into specific fields and make cutting edge discoveries. The field the brightest Jews got into has the most intellectual prestige, so their glory there illuminated their own intellectual profile, but they did so with IQs around 107-110, and not 115.

SSC had a good post on Israeli underperformance: http://slatestarcodex.com/2017/05/29/four-nobel-truths/

As for dropping Ashkenazi IQs...they're almost certainly hit by the same dysgenic trend everyone else is, about -4 points from von Neumann's time. Add some losses due to intermarriage on top of that and a drop from 115 to 110 seems reasonable.

Jig Bohnson said...

What's this about Israel not having an impressive economy? Israel is 9 miles wide surrounded by hostile basket case countries and has been at perpetual war in one form or another for all of its 70 years, and is also 20 percent Arab, 10 percent religious wackos who don't work, and until recently has had essentially no exploitable natural resources. In spite of that, it has the eleventh highest GDP per capita in the world (!), the third most (in absolute number, not per capita) companies listed on the NASDAQ, and is second (to South Korea) in R&D spending per capita in the world. I'd say that's pretty impressive. (And no, mindless regurgitators, very little of that is attributable to annual US aid to Israel, which is around 1.5% of Israel's total GDP.)

All of that points to the presence of at a minimum a substantial sub-population with a mean IQ of around 115. You don't get the eleventh highest GDP per capita from nothing without that.



Sid said...

Anon,

Good point. Dysgenics and outbreeding may well have had a deleterious effect on IQ.

From what I remember, the percentage of National Merit Finalists has a surprisingly low number of Jews. Back in the day, Jewish mothers were notorious for being the Tiger Mother of the time. Now that they're closer to other white Americans culturally, Jewish mothers tend to let their kids slack off compared to what they would do before.

Granted, you need a lot of g to be a National Merit Finalist, but IQ is more malleable in children and adolescents than what it ultimately will end up being in adults. So it's more decisively "helpful" to have a Tiger Mother who is angry you got a 95 on your English essay instead of the 100 she was expecting when it comes to high school achievement.

Kipling said...

Tempest in a teakettle, right? The 115 number always seemed way high, while neither 107 nor 110 would shock me. I enjoy the sound and fury but it signifies nothing. Blair is just as genocidal against me and mine as Soros.

thekrustykurmudgeon said...

I'd like to think of myself as moderate on the JQ. Yes, there is probably a lot to the holocaust revisionist argument; Yes, jews in the u.s. shouldn't be dual citizens; but I don't mind having jews in the united states as fellow citizens.

Getting to the brass tacks of jewish IQ - my view is that they are pretty good at the "rhetorical arts" such as law, academia, media etc but probably about neck-and-neck with other whites in more objective things like STEM or what have you.

The Z Blog said...

What I found amusing about the Beale post is he correctly pointed out that people tend to conflate Ashkenazim with all Jews (Ashkenazi, Sephardic, Mizrahi, etc). Then in his zeal to "prove Jews are not that smart", he does the same thing. All discussions of this topic in the context of the JQ are limited to the Ashkenazim.

In America, Ashkenazim are 90% of the Jews. Sephardic Jews immigrated in small numbers, but they also married into the local population at much high rates than Ashkenazim that arrived in the 20th century. There's also the fact that the Jews from the Pale of Settlement should probably be treated as a separate group.

That's not an unimportant topic. The studies done have put the range of Ashkenazim IQ between 107 and 117, a spread of two-thirds of a standard deviation. Imagine if the Pale of Settlement Jews are clustered at one end while German Jews are at the other. The gap between 117 and 107 does not sound like a lot, but it means about 30 times more geniuses.

There's another thing to keep in mind. Reality. When you look at areas where all the hobgoblins of the anti-Semites are excluded (math, science, chess, etc), the results point to an Ashkenazim IQ around 112. Group evolutionary strategy does not explain Jewish performance in chess competitions.

pointED, HAD not explainED.

The past performance is indication of past capabilities, not of the current ones.

(1) German Jews were overrepresented, but were they similarly spread in cities/villages as German gentiles?

(2) Are modern Jews the same in terms of genetic as Jews from the beginning of XX century? Google tells me there was very high intermarriage rate, meaning quite a lot of modern Jews are not exactly "pure" Ashkenazim

DissidentRight said...

Well, I think that pretty conclusively demonstrates that Jewish IQ is not 115 as I once thought.

In unrelated news, I am starting to see signs that Alt-Christian vs. Alt-Secular makes a difference on the JQ. Which makes perfect sense and is absolutely hilarious.

5318Anon,

It's not talked about enough--because human biodiversity is never talked about enough!--how as Nature's understood influence rises and Nurture's understood influence declines, noblesse oblige becomes an easier moral sell and so does pity and sympathy for those bumping along at the bottom. This shift is bad for Jews since it insinuates that they didn't do anything to earn their high perches. We don't tend to give people credit for choosing their parents, after all.

szopen,

Jewish intermarriage rates are now approaching 75% among non-Orthodox Jews. The vast majority (though not all) Jews in the GSS sample self-ID racially as white. That's a pretty good indication that they're probably Ashkenazi, but it's not guaranteed.

Sid/Anon,

Yes, the intermarriage seems the most likely explanation to me. It is one Jewish publications talk about occasionally (though not as often as I'd expect them to) and that non-Jewish publications never say a word about. But it's a big deal. If three out of four non-Orthodox Jews are marrying non-Jews, Jewishness is going to look a lot different in a century than it does now.

Had a back and forth with Richard Spencer on twitter over the weekend. He disputed the idea that Jews in Israel are more secure than Jews in the diaspora. I doubt it--more secure from bodily harm, sure, but far less secure in terms of existing distinctly as Jews in the future.

Jig,

The CIA World Factbook puts it at a little below the EU mean, about in line with italy and South Korea. Yeah, yeah, if you can't trust the CIA, who can you trust? Still, that's just about exactly what I'd expect given its demographics and history.

Kipling,

That the discussion is happening in several places is more important than the specifics of each discussion. "Jewish privilege" needs to be a recognizable concept. If the 2% don't like that phrase, then let's offer them this compromise--stop using the phrase "white privilege"!

Krusty,

Yes, the high voibel definitely shines through in their accomplishments. High visuospatial provides a good living for STEM professionals, but its takes high verbal to become uber rich.

Z,

Well put. You are our voice of reason on the JQ.

Yes, it was humorous how VD did that. It's almost as though he wrote the latter part of the post first and then added the first part latter and then didn't read through it from start to finish after that.

Interesting:

https://www.cnbc.com/video/2018/05/07/top-reading-recs-from-buffett-munger-and-gates.html

Buffett, Munger and Gates all are reading stuff to try to convince themselves that the world is getting better. Which it is in a number of ways.

Buffett and Munger have a combined age of 181 so they aren't going to be around all that much longer. Before they go, will someone please ask them about Steve Sailer's THE MOST IMPORTANT CHART IN THE WORLD?

The present and coming demographic shift toward the least productive people in the world would seem like a relevant question, no? I mean it seems like perhaps the most relevant question related to human progress, no?

There is more truth in this deplorable corner of the blogosphere than there is from the world's leading lights. I suspect that Buffett knows a lot more than he lets on since Planned Parenthood has always been his charity of choice. Bill Gates probably knows too. But as Gregory Cochran notes, "you have to state important facts every so often, or nobody knows them anymore".

Buffett/Munger/Gates think its a problem that people with pessimistic views make their views known, which led, alas, to Trump. Or at least, that's how they talk.

I feel pretty sure that Trump and his Deplorables have instead planted a flag in history which will show that we *knew* all the way back in 2016, of the biggest issue of the third millennium. We the Trump voters of 2016 will be proved by history to be the greatest intellectuals.

Dan,

Bill Gates was allegedly obsessed with IQ testing at Microsoft. He has to have an understanding that more mouths to feed in Africa is going to make it harder to make sure Africa is fed. How could he not connect the dots? It has to be a lack of intellectual courage (and a sense of reputational self-preservation, I guess).

Feryl said...

The comments about "marrying out", or even more ludicrously, "purity", are kinda funny. Ash. Jews are to begin with the by-product of several ethnic groups (those hailing from the Middle East and also from Europe). If anything, the real out-marriage, or betrayal of the blood, would come from eloping with knuckle dragging prole gentiles, since Ash. Jews were drawn from the elite of two different worlds (the ME and Europe). I suppose introducing more Northern Euro blood would be a change of pace, given how non-blonde Ash. Jews are.

It wouldn't surprise me one bit that in the race to the cultural and ethical bottom of the last 50 years, that successive generations of Jews are getting worse at picking partners. That being said, there's no way to discern Jewishness exactly on the GSS. There are way too many Jews self-IDing as Buddhists, atheists, hell, even some converts to Christianity are probably along for the ride too. Looking at pre-Boomer Jews would be easier, since they came of age before the 70's which is the decade when all kinds of multi-culturalism and decadence began to get out of control (the 60's was about some of the Boomers telling tradition to fuck off since most people still were, well, traditional).

Dan said...

AE,

The most charitable interpretation is that Bill Gates has the power to pull down the scary curve of The Most Important Chart In The World and getting labeled a racist would wreck his ability to help solve it. I hope that is the case.

Bill Gates gushed about this book by Swedish POS Hans Rosling
https://www.amazon.com/Factfulness-Reasons-World-Things-Better/dp/1250107814

Hans Rosling's job seems to be to soothe everyone by spouting off ways that the world has gotten better in the past while ignoring the biggest issue of all.

It would be extremely useful if someone on the alt right wrote:

Factfulness II: Ten Reasons Why Things Are Worse Than You Think

Dropping HBD truth on the heads of the world. The name is very important as a counter to Rosling and if Rosling's estate sued, all the better because of the Streisand effect.

There's a good blog (called Unfoldinghistory) by a professor of history. Being a Boomer, he himself admits that he sees many weaknesses in his generation, and a willingness to roll the dice because, well, it just feels right is something that he says many Boomers do. Boomers like Bill Gates may by superficially concerned with solving a problem, but at the end of the day, they often succumb to their feelings at the expense of rationality. That blogger says that many of the West's great achievements could be credited to the triumph of reason over sentiment and toxic partisanship, yet it's precisely the latter qualities that Boomers embraced in the 60's and have never let go of, in spite of mounting evidence of diminishing returns.

If it feels good to simultaneously have intelligent workers while promoting reckless aid to Africa, then well, go ahead and do it.

The blog often contrasts the materialistic and productive consensus of most of the citizenry in the 1930's-1960's with the emphasis on one's comfort, pleasure, and feelings that began to dominate in the 1970's, the decade in which social popularity of big programs and team-work collapsed. He says that Boomers encouraged unhappy people (who frequently were young and also racial, sexual, and political minorities) to soap box their rage and sorrow with no concern for it's effect on our ability to put differences aside and get things done. Hell, for that matter many Boomers relished the inability to get things done as they once were, given that it freed up more time to screw around. It was from this attitude that PC grew; no longer was it shameful to be a self-centered dick, so long as your were perceived to have a legit grievance. The perception, the feeling of being hurt and unloved has grown to surpass traditional Western and Anglo conceptions of justice in importance and status. It's hard to think of something more audacious than the Boomers mocking other generations for being whiners, but, there ya go.

Also a big deal is that according to the blogger, it's important that Boomer type generations not be exposed to institutional failure at a young age, as Boomers were with Vietnam. They can be conditioned to either begrudgingly respect authority, or reject it entirely. Should the latter happen due to a big mistake by leaders, they will never consider the idea that the individual should take a back seat to authority, or to the group.

Sailer mocking the Left's saccharine rhetoric, that has no concern for any widely shared concept of reality or truth, is appropriate. But his peers are to blame for pedestalizing victimhood and personally felt notions of justice back in the 60's and 70's.

Feryl said...

As good a time as any to note that Brits are the least sentimental people in the entire world, which is exactly why they became such adroit analysts and wordsmiths. And also why they (once) were so productive, and had such a steady hand with their political affairs (within their own borders, at any rate). Teutons outside of Britain are fairly similar, too, though esp. in Germany, they can be a bit too.....Tightly wound and credulous. Traditionally, Brits would find credulity to be perhaps the most shameful sin of all.

Not for nothing is the word "reasonable" such a key element of the Anglo legal system. Being reasonable.....Whatever happened to that? Ask the Boomers.

For our elites their secular religion is their fervent belief in Progress.

If you want to break to souls our secular elite, hit at their belief in Progress. This is their substitute for religion and it is a false God that can be smashed on the rock like any other idol.

Maybe its good that Hans Rosling has written about how great things were way back now, so that we can use the same statistics going forward.

The elites worked to wreck the religion of the poles. Well they are about to have their Religion (Progress) wrecked. Buckle up.

Jack Nicholson, in one of his movies, once said that his character writes women well because "I take a man and strip out reason and accountability". The modern West is the West with no reason or accountability. Boomers are a Western generation with no reason or accountability. Unfolding History talks about many of the stupidest foreign policy blunders of the last 25 years being motivated by Boomers whimsically deciding that it's no use being concerned with tradition or other people's opinions, or even realistic notions of what's beyond our grasp, and just forging ahead with whatever half-assed scheme you think sounds good enough. Meanwhile, the most flagrantly inept shot callers who by any logic ought to have been demoted to Walmart greeter often continue to ride high.

There's mountains of evidence to convict many of our elites of treason, fraud, graft, etc., but nothing happens. Seems as if in our post-modern legal and political system there's no consensus agreement on what constitutes inappropriate conduct anymore, for the most part. As best we can tell the only way to really get in trouble is via rape, pedophilia, racism, sexism, and homophobia. Everything else goes.

Feryl said...

Progress is fine when it had good foundations. As in being rooted in logic and reality, and evolving but common sense standards of science, politics, behavior, etc.

That all got thrown totally out the window by smartass Boomers in the late 60's, who society completely caved to by the mid 70's, I guess for no other reason to make them SHUT THE FUCK UP.

For us Gen X-ers and Millennials, we've for decades had to pay lip service to the (heavily) enforced standards of Boomer created sentiment over muh feelings and muh civil rights. If we don't, our ass is grass. And nobody sure as hell ever asked us if we wanted it this way. Conservative Boomers could've righted these wrongs by agreeing to economic accountability (via prog. taxes, not deregulating things, etc.) in exchange for maintenance of our intellectual and social culture, but nope. God forbid you ask Boomers to ever make compromises and accept the fact that they can't get their way on everything (such refusal is going to make it unlikely that Millennials or Gen Z will ever get anything they wanted, in terms of how society should function).

"While 4.2% of gentile whites score 10 out of 10, 12.1% of Jews do." -- could one use the method of thresholds here? La Griffe du Lion explains method of thresholds here:http://www.lagriffedulion.f2s.com/fuzzy.htm

Normsinv(.958)= 1.7279 standard deviations from the mean
Normsinv(.879) = 1.17 standard deviations from the mean.

The difference between the two is .5579 standard deviations.

My other comment is I suspect that Ashkenazi and gentiles differ in conscientiousness. Conscientiousness is a big predictor, after IQ, of life outcomes. I wonder if there is a way to measure that in the GSS.

Feryl,

I am not sure what you are aiming at. The question whether Ashk. Jews are same group now as hundred years ago seems to be not funny at all and highly relevant to the question of their average IQ.

Europeans are results of mixing of at least two very different ancient group. Does that mean Europeans as a group NOW do not exist and you can't say about "mixed" Europeans?


It does not matter how Ashk. came to exist. What's matter is that the resulting group is purported to have IQ significantly higher than neighbouring population. That means that if that group, however it was created, started to mix with a population with lower IQ, due to regression to mean the resulting offspring will have, on average, lower IQ.

Imagine you would separate a herd of horses and one part would be bred horses for speed. Finally you get ultra-fast horse-racing breed - and mixing the horses from ultra-fast breed with normal horses will get you horses only somewhat faster, despite the both groups would come from the same herd.

Hence I think it is more than possible that AShk. Jews the beginning of XX century had higher average IQ than people claiming to be Jews (Ashkenazi) now.

Dan said...

"Hence I think it is more than possible that AShk. Jews the beginning of XX century had higher average IQ than people claiming to be Jews (Ashkenazi) now."

Possible.

Another thing is this:
I think an error that just about everyone makes is to assume a simple normal distribution when it comes to populations and IQ, extrapolatable all the way up to genius. But there are specific genes involved; either you have them or you don't. There may be some gene that is very useful for high brain function in that population which could make for a barbell-type distribution. The folks who have that gene are non-continuously better than those without.

Consider physical strength in the example of bully whippets (a subset of the whippet dog breed with a single genetic difference -- do a google image search on bully whippet to see the point). If you assumed whippet size were a normal distribution, you would be wrong. Surely many genetic differences account for whippet size but one genetic difference is really important.

I don't know the answer to the JQ, but I suspect the normal distribution isn't followed.

Don't we still need to have a reliable median for that method? The artificial restriction of range means our median values are what is suspect.

I think you may be onto something.

Dan,

That's certainly the case among among Jews in a religious sense. It could be among Ashkenazis, too, though I'm unaware of any evidence that suggests as much.

"Hence I think it is more than possible that AShk. Jews the beginning of XX century had higher average IQ than people claiming to be Jews (Ashkenazi) now."

" Possible."

If one takes into account that Jews born before circa 1940 had to adopt a highly defensive and insular posture as the result of many generations of migrations, pogroms etc. while still studying up for high IQ occupations, then it stands to reason that for quite some time Jews infrequently out-married (and occasionally attracted gentile converts), and when they did so it was only with very intelligent gentiles. The ancestry of Ash. Jews reveals that they did indeed absorb Euro gentile DNA over time, but one can only assume that it was VERY selective out-marriage/conversion that took place.

Jews in North America in particular have now had (relative) ease of blending with gentiles for over 50 years, and the results speak for themselves, with out-marriage rates being perhaps at their greatest levels ever.


"Europeans are results of mixing of at least two very different ancient group. Does that mean Europeans as a group NOW do not exist and you can't say about "mixed" Europeans?"

Northern Europeans are less "mixed" than Ash. Jews. What I'm getting at is nerding out over "purity" or what have you is a pointless waste of time, and it gets more ridiculous the closer you get to Sub-Saharan Africa. Not that it stops Japanese or Han Chinese from defining themselves as basically separate races as a matter of ethnic pride. In other words, there's no such thing as a "pure" or "typical" Ash. Jew. They aren't East Asian, fer crying out loud, and they aren't even Swedish or Catholic Irish in terms of genetic homogeneity. Ash. Jews are a cross between Semites and Med. whites, mostly genetically notable for their extremely high IQ and verbal orientation. Presumably, if Ash. Jews were very selective about breeding with Asians or Northern Euros, there wouldn't be much change in their IQ genes, except perhaps being more weighted towards visual-spatial abilities (blue eyed whites and Asians best dark eyed whites at stationary target shooting).

I agree that mixing with dumb gentiles has probably diminished Ash. Jew IQ. But that says more about Western decadence and dysgenics than it does keeping Jews free of intermarriage altogether, which is both impossible and not in keeping with history (Ash. Jews to begin with being the result of mixing Semites with high IQ gentiles).

What's the male female difference?

Imagine you would separate a herd of horses and one part would be bred horses for speed. Finally you get ultra-fast horse-racing breed - and mixing the horses from ultra-fast breed with normal horses will get you horses only somewhat faster, despite the both groups would come from the same herd.

Except they're not the same herd at that point, there's a general population and a selected population.  The selected traits will be much more prevalent in the selected population.

What likely happened to the Ashkenazim some centuries ago is what is on-going in the Amish today.  The Amish have "rumspringa" and let their teens decide which society they want to be part of.  Those who "boil off" leave the remaining population with more Amishness by selection pressure.  IIUC the Ashkenazim encouraged their least-successful members to convert to Christianity, taking their traits un-suited to the Ashkenazi model with them and leaving the rest.  Cutting out 10% per generation can achieve large shifts in gene frequency in a few hundred years.

I have been chased by Jewish women and mistaken for Jewish by an Orthodox, probably because I am sharp.  Today I am red-pilled on the JQ.

Passerby,

Marginal. Women do 1/20th of a SD better--0.8 IQ point advantage by this method, but of course women tend to do slightly better than men on verbal portions of IQ tests and worse than men on visuospatial portions.

Mr. Rational,

The Amish have the TFR to sustain boiling off. So do Mormons. Ashkenazi Jews do not, though. Elite status arguably matters more than population quantity. After all, George Soros is just one man. Otoh, it takes a network. I think American Jews a generation ago will look a lot more distinct than American Jews a generation from now do.

Joe,

... is going to make this an executable program relevant to the post's content. Will share when he's finished.

We're not talking today.  We're talking pre-contraception, when the Ashkenazim were a distinct population in Europe and noted for out-breeding their ability to feed themselves (as did so many others).  It was under THOSE conditions that their unique mix of abilities was refined.

Thanks.

AE, What is the age range of the population sample?

Audacious Epigone said...

Passer by,

Ages 18-89 Wordsum varies a little by age, peaking around the late 50s and early 60s.

The Jewish Race is a social construct, and therefore does not exist. Why do so many Jews get worked up about the Holocaust specifically? It’s humans killing humans, just like the Holodomor, the Katyn Massacre, and the liquidation of the kulaks. There’s more genetic variation within the Jewish “race”. Than between Jews and Gentiles. But people who think they are Jewish insist on following a racial supremacist ideology, as detailed in the Talmud. To solve the problem of institutional worldwide racism, we need to promote mass immigration into Jewish areas, and only Jewish areas. Jews need to blanda upp.
