Race and IQ news + new studies

Controversial new studies and content on: Chinese IQ, Ashkenazi IQ, mixed-race IQ.

Great guy btw, he's also one of the few non-cucked WNs right now.

Here's the two studies I'd like to cover:

https://www.researchgate.net/publication/354766492_Genetic_Ancestry_and_General_Cognitive_Ability_in_a_Sample_of_American_Youths

Here we apply this technique to examine SIRE differences in g. We find that
African and Amerindian ancestry are strongly negatively associated with general
cognitive ability among African, Hispanic, and other American subsamples. This
replicates previous research which showed that genetic ancestry predicts
cognitive ability, independent of socioeconomic status and phenotypic
discrimination variables which are the usual suspects (Kirkegaard et al., 2019;
Lasker et al., 2019; Warne, 2020). The importance of such analyses within SIRE
groups is that they shed light on the cause of g differences between SIRE groups
with respect to similarities in developmental processes (Rowe, Vazsonyi &
Flannery, 1994)

The ancestry effects are consistent in direction across subsamples and hold
after controlling for a wide array of economic and social factors, including migrant
status, SIRE, ethnic attachment, measures of discrimination, phenotypic indices
of race, and general SES. These results suggest that African, Hispanic, and other
groups have inherited alleles from their African and Amerindian ancestors which
make them liable to lower levels of g. In fact, as seen in Table 5 (Model 2), 100%,
76%, 81%, and 100% of the respective Black, Native American, Other, and
Hispanic SIRE effects were explained by genetic ancestry. This association
between genetic ancestry and g suggests a partial genetic basis for observed
SIRE differences.

t should be noted that the polygenic scores represent genetic variation that
is caused by common alleles, not genetic variation that is caused by rare alleles
under mutation-selection balance. The causal alleles that are tapped by polygenic
scores are ancient. Most were already polymorphic 60,000 years ago when
people left Africa and spread all over Eurasia. Today’s racial allele frequency
differences are the cumulative effects of selection and genetic drift acting over
more than 2,000 generations, while rare variants under mutation-selection
balance are much younger, no more than one or two millennia or even less.
Therefore it is predictable that genetic race differences that evolved over a long
time are differences in polygenic scores but not necessarily differences in
mutational load. The latter are the result of strength of selection during the last
centuries.
Overall, the results suggest that genetic variants related to general cognitive
ability vary between source genetic populations and have a causal effect on
intelligence. Because individuals within SIRE groups differ in their proportion of
African, European and Amerindian ancestors, general cognitive ability varies by
genetic ancestry within SIRE group

We conducted an admixture study to assess the association between cognitive ability and European ancestry in the African- and European-American populations. Earlier researchers (e.g., [51,52]) were unable to detect significant relationships between ancestry and cognitive ability. We, however, found a strong, significant association between European genetic ancestry and cognitive ability, confirming the recent results of both Kirkegaard et al. [24] and Warne [25].

Rushton and Jensen [9] called for modern genetic studies to test the hereditarian model. They predicted that “for those Black individuals who possess more White genes, their physical, behavioral, and other characteristics will approach those of Whites” ([9], p. 262). In the present study, we confirmed that this was the case for general cognitive ability. Moreover, we showed that the association between European ancestry and g was substantially mediated by eduPGS rather than skin color PGS. These results provide support for a hereditarian model.

Both these studies replicate one another, and essentially provide to us the following:

• “Consistent with predictions from the genetic hypothesis, African and Amerindian ancestry were both found to be negatively associated with [IQ / general intelligence]. The association was robust to controls for multiple cultural, socioeconomic, and phenotypic factors.”
• Higher-levels of European ancestry in African-Americans correlates to higher-IQ
• Common alleles in various human populations can predict intelligence & various SNPs

Sadly, however, the professor who spoke up about his findings was fired:

His dismay turned to outrage when he discovered that one of the authors, Bryan J. Pesta, was a tenured professor in Cleveland State’s business school. O’Brien’s home institution was essentially providing a soapbox for racist pseudoscience.
He had a history of political activism, so he did what came naturally, talking to students and professors about Pesta’s article, and trying to get him censured.
“I didn’t know anything about academia and how difficult it would be to do anything about it,” O’Brien said. Among his acquaintances at the university, he said, “I didn’t encounter a single person who knew anything about him.”

Ofc, it was some Liberal richfag

yet another study proving us right,. but this wont really change anything in the grand scheme of things since there is already a boat-load of data supporting race and IQ that has been completely ignored by the mainstream

Im sure it's some high IQ post but i can't read it im too demoralized.

Yup, and these are the same people who claim that you can chose your sex

ovER for demoralizedcels

Just from a cursory glance, it is interesting how the mean IQ predicted from the line of best fit on the graph below (approx. -1.2 SD so 15 × -1.2 = -18 and 100 - 18 is 82) of African Americans with no self reported European ancestry almost perfectly matches the estimated genetic IQ of racially pure black africans in South Africa (80 according to Pumpkinperson)

(I assume the numbers next to the y axis is the standard deviation of General Intelligence)

Didn't know blacks had the capacity for honesty

How do they self identify as such specific numbers? Yea i am 94% european. Would you not go in 25% increments as in your grandparents ethnicity make up?

Your grandparents could also be mixed

Or they could just be making SHIEEET up

Yea i know, it did surprise me though to see so many oddly specific numbers.

High-IQ for catching this

Interesting how the g factor matches almost perfectly.

@Koomersarj @based_meme

The main IQ tests (administered by psychometricians and doctors), like the WAIS, are the best estimates of g. It's extremely accurate, and I always find it funny how IQ tests make people incredibly salty.
