🧵 Eskimo/Inuit advantage in visual memory & perceptual cognition being mostly genetic in origin: some lines of evidence

Inuit children outperformed whites in visual memory comparably _regardless of_ acculturation level to majority society + outperform in Raven's matrixes For comparison: As for one Sami (people of Northern Nordics) group from area w/ little contact with dominant culture & another from area w/ more frequent contact w/ dominant culture: _Both_ showed higher visual perceptual skills than Finns; degree of acculturation had no impact.

Ashkenazi Jews are on average more disagreeable & open to experience than gentiles. These are very heritable traits that, along w/ high mean general (& verbal) IQ, result in their huge overrepresentation in a plethora of competed intellectually demanding domains.

Why so? /1 Not because of their "Jewish culture" supposedly elevating these traits postnatally (Sephardic & Mizrahi Jews have been for a long time on average even more Jewish culturally). But, for ~millennium in Europe, aspects of Judaism combined w/ external factors to maintain an... /2

🧵on the intelligence of North American Ashkenazi Jews and essential lines of evidence for the hereditarian—i.e., mostly genetic—hypothesis Using data from 17 IQ studies (15 in USA, 2 in Canada) during a period of 50 years (1944–1994), I compiled the following table.

As Ashkenazi Jewish children age, the only Performance IQ scale subtest that raises relative to gentiles is Coding, and the raise is barely over 1 IQ point. It happens to be the one with BY FAR the SMALLEST g (general intelligence) loading. Why interesting? Coding doesn't.../1 ...differentiate much b/w low & high SES parents & offspring. g loading & heritability have positive correl.

Ashkenazim Verbal IQ increases A LOT, Performance very little & is due to low g, low heritability test.

White gentiles w/ decades of scientific research on very high mean
- visual memory of Australian aboriginals,
- perceptual reasoning of Inuits,
- Performance IQ of Chinese, &
- Verbal IQ of Ashkenazi Jews
would've by now copied recipes if it was possible.

They are in genomes. PS Bear in mind that Sephardic Jews, THE population with the deepest connection to the Jewish culture outside of Ashkenazim, haven't - in centuries - been able to copy the presumed magic recipe.

Why? They've faced the same obstacle: the recipe is in the genome not of their own.

🧵Memory & cognition of aboriginal peoples

Inuit children outperform whites in visual memory comparably regardless of acculturation level to majority society + outperform in Raven's matrixes.

Sami outperform major popul. in 2 perceptual tests.

"North Africa was never conquered by the Mongols...internal causes were responsible for the divergence between Christian Europe and the rest of the world" "In sum, between 500 and 1500 AD the Western Church created a system of social reproduction that would have far-reaching demographic, behavioral, and economic consequences."

🧵"Discrimination of Jews in Soviet Mathematics"

Jews were ~2x MORE likely to have been Olympiad winner (~3x MORE likely to have been a multiple Olympiad winner) yet were 7x LESS likely to have been admitted than gentiles (non-Jewish whites).

From 3038.org/press/shen.pdf "By 1973, the "special program" of elimination of...especially Jews, was in full swing."

In these two institutions, 61 % of gentiles accepted; 11 % of Jews were accepted (despite their higher mean cognitive ability & proportion of geniuses)

From 3038.org/press/shen.pdf

🦣🧵compiled from papers & articles about Ashkenazi #Jewish intelligence & its (high g & verbal IQ) causal link to their stratospheric achievements in domains rewarding high g & verbal #IQ yet no high visuospatial IQ, & its origin (=evolutionary selection --> genetic chance) Achievements at the highest levels in arts & sciences 🏅

Jews, never comprising more than <0.3 % of world population & <2 % of developed world population, up until early 2021 had ammassed these achievements.

Estimate for mean IQ of Ashkenazi Jews is ~107 in early childhood (WISC) & 113 by early adulthood (WAIS). These tests give equal weight to their Verbal & Performance IQ domains.

👇IQ tests (not only WISC/WAIS) administrated in North America during a 50-year period (1944-1994) Ashkenazi Jews do much better on subtests with higher verbal, numerical, & conceptual factor loadings than perceptual & spatial ones; they excel at comprehending & applying conceptual understandings to problems that are presented in or transferred into a verbal or symbolic mode.

🧵Some genetic diseases among Ashkenazi Jews are linked to evolutionary selection for high general & verbal intelligence:

J. Diamond was the 1st to argue that chance cannot explain the high prevalence of so many lysosome storage disorders in a single population (Ashkenazi Jews). They’re about a hundred times more likely to have Gaucher’s Disease, a hundred times more likely to get Tay-Sachs Disease, ten times more likely to have torsion dystonia, et cetera. Riley-Day syndrome – three hundred times as common in Ashkenazi Jews as in anyone else.

"“testing results regularly show that math students in the United States are lagging behind those in other industrialized nations...within the country, there is a persistent racial gap in achievement.”"

Same in Finland despite of equalizing education (!)

quillette.com/2022/02/13/its… How would progressives feel if policies would eliminate e.g. overrepresentation of blacks in top-level college & national basketball & American football leagues? In track & field sprints? In hip-hop?

Jews & Asians in universities? Oh, sorry, it's been done already.

Arthur R. Jensen on Eysenck (hanseysenck.com by @KirkegaardEmil):
“Eysenck was a kind of genius...or at least a person of very unusual talents, and the only person of that unusual caliber that I have come across in the field of psychology."

amren.com/news/2018/10/a… "Still, Prof. Jensen did not abandon his conventional beliefs in the power of environment to raise or lower intelligence, and went on to publish 30 papers and build a non-controversial reputation before he finally concluded that Eysenck and Burt were right."

"That their [fraternal twins who grew up together] IQ scores...differ significantly more than those of identical twins who didn’t even grow up in the same family suggests that heredity is more important than environment in determining IQ." "studies have shown that the IQs of adopted children are closer to those of their biological parents than to those of their foster parents...in a family whose children are all adopted, there will be a greater variation in IQ than in a family whose children are all biological."

It's remarkable that compared to #NYTimes who reads like a notebook of evolution denier Lysenko, Stalin's favored "scientist", #AmericanReneissance reads like a peer reviewed science journal as for content, arguments, & accuracy in #HBD (human biodiversity) related content (!). Having read tens of AmRen articles, I've not discovered pure racisim. It's been scientifically informed, utilitarian & logical albeit at times blunt population level analysis & worry about the West's outgroup favoritism - not discrimination against any given individual.

"deaf children get low scores on verbal intelligence tests. However, they get normal scores on non-verbal tests and by the time they are adults they have overcome most of the verbal deficit." "children with catastrophic motor disabilities, who lead lives that are severely restricted by any definition, apparently have higher tested intelligence levels than blacks who are not physically handicapped."

Amazon has removed this interesting book as part of their social "justice" campaign so I'll be quoting it here.

"Fuerle’s Erectus Walks Among Us is another example of race-realist scholarship that could not have found a place in today’s mainstream." "Erectus Walks Among Us is several books in one, all written from a firmly race-realist perspective. It is a primer on evolution and genetics, a catalog of how populations differ, an introduction to sociobiology and the concept of genetic interests, and a plea for white survival"

Imagine environmental & cultural factors explained the black:white intelligence difference. It would be magical & not follow any internal logic. Why would blacks & whites matched for IQ have a mean 0.5 SD dif. in visuospatial IQ? Or:

"When you compare black and white mean scores on a battery of subtests, you do not find a uniform set of differences; nor do you find a random assortment. The size of the difference varies systematically by type of subtest."
