By the end of the 20th century, Whites, Indians, Coloureds and Blacks in South Africa averaged IQs of 98, 92, 82, and 69 (UK norms). Although all four “races” were in school when tested and used to paper-pencil tests, and although the test used (Standard Progressive Matrices) was culture reduced, there were enormous difference in the quality of environment the four races were exposed to including the biological environment which affects brain growth. I tried to correct for this by comparing the different rates of stunting (low height), but as commenter “some guy” noted, this measure is too confounded with genetic height to be a good proxy for environment.
Perhaps a better proxy is Human Development Index (HDI) which combines income, education, and life span. While life span is confounded with genetics to some degree, being reared in a poor uneducated home is a clear environmental effect.
In 1991, South Africa’s Whites, Indians, Coloureds, and Blacks had HDIs of 0.901, 0.836, 0.663, and 0.50 respectively (see table III).
To put these numbers in perspective, I wanted to know the HDI of black Americans because black Americans have continued to score 15 points below white Americans for roughly a century, and it doesn’t seem to matter whether they’re reared by their biological parents or adopted into White professional homes. Thus black American HDI is perhaps a ceiling beyond which environment much affects IQ.
An article in The Atlantic (October 14, 2014) by Theodore R. Johnson reported their HDI but I don’t think a 2014 figure is comparable with the 1991 figure for South Africa’s races, both because living standards have changed over time and so has the method of calculating HDI. But assuming the relative ranking of black America has been similar over time (slightly above Saudi Arabia and slightly below Qatar) then in 1991 they had an HDI of about 0.705 (Saudi Arabia) to 0.745 (Qatar) or roughly 0.725.
Black Americans (1991 HDI 0.725) score 15 points lower than white Americans, but 16 points higher than South African blacks (1991 HDI 0.5). The former gap is arguably 100% genetic judging by the results of the Minnesota transracial adoption study suggesting HDI has no effect on IQ once you hit at least 0.725. The latter gap is probably 31% genetic, because Black Americans are only 75% Black. Adjusting for this reduces the latter gap to 11 points suggesting that for people with HDIs below 0.725, subtracting the HDI from 0.725 and then multiply by 48.9 gives an estimate of how much Raven IQ (taken by people in school) has been supressed by environment.
So the IQs of South African Whites and Indians (98 and 92 respectively) are probably not supressed because their 1991 HDIs were above 0.725 but Coloureds were 0.062 below this threshold, so multiplying by 48.9 suggests their IQs were supressed by 3 points. This would raise them from 82 to 85, the same as African Americans.
Native Americans
According to one study, “by 2001, the American Indian and Alaska Native population and the Canadian Indigenous population had…HDI scores comparable to South Korea or the Czech Republic and Belarus or Trinidad and Tobago, respectively.” In 1991 Czech Republic had an HDI score of 0.733 and Trinidad and Tobago, 0.67. Averaging just those two (couldn’t find 1991 data on the other countries) suggests American Indians and Arctic people had a 1991 HDI of 0.702. This suggests their Raven IQs are supressed by 1 point. This is consistent with a study that found that several years of foster care in white homes did not at all improve the IQ of these.

peepee is an extremely sexuallly frustrated black woman who has embraced marxism because PRC and DPRK and her bizarre attraction to chinamen. but she has yet to defect to north korea…she’d find the north koreans are super racist…no north korean man would be allowed to touch her even he wanted to…sad.
peepee sees this picture and she says, “whoomp there it is…that’s what i’m talkin’ ’bout.”
and yes.
the irish of manhattan score higher than the jews is a totally reasonable hypothesis, but because…
the pill personality is one of those low IQ ghetto jews who don’t know what manhattan, what new york city people call “the city” or just “new york”, coterminous with new york county, has become…
even its shittiest neighborhoods are way too expensive for poor people.
it’s a privilege to live in manhattan.
maybe parts of the far north like parts of harlem and washington heights are still shitty, but i doubt it.
it’s like disneyland.
very very different from what it was in the 70s and earlier.
very.
No its not reasonable dumbass. Jews score much higher. We have the test scores so shutup.
you have the test scores of irish americans living in manhattan?
LIE!
you both are worse than RR with your backwards logic and your compulsions to run around in circles.
“The latter gap is probably 31% genetic, because Black Americans are only 75% Black.”
Where did the 31% come from?
IQ 85 vs IQ 69 is 16 point gap, but without white admixture it would be 80 vs 69 or 11 point gap, so 5 of the 16 points is genetic.
so nyc is down the ranks ut tokyo is still #1.
nyc metro is between 19 and 24 million depending on how wikipedia counts it.
manhattan is 1.7 m or 9% of the metro.
manhattan is where everyone in the metro would live if they could afford it + where people from all of the US and the world want to live…
it was not always so elite a habitation.
but today even a shoebox (150 sq ft apt) on the lower east side will cost $2,000 a mo. it’s insane.
So you won’t acknowledge gorilla achievement despite no HDI?
^^^^
Answer this.
LOL! Gorillas actually have very good environments because they are living the life they evolved to live. Human biological development suffered precipitously when we switched to agriculture and only the developed world has recovered.
^^Totally and categorically false. Many gorillas are endangered and suffer from human encroachment in their living areas meaning many do not receive an education, healthcare or social services which can effect their cognitive development.
Pill youre retarded do you know anything about science!? you dont even know how to properly use “effect/affect” how the fuck are you going to tell people who devote their lives to science (especially as a fucking outsider) that what anything you say is credible?
im sick and tired of autists misconstruing everything everybody says on here. either you know or you dont simple as that stop guessing at things you simply cannot comprehend just to appease your irrationalities!
he’s making fun of social justice warriors
i get the joke but sometimes even Pill is autistic enough to let his jokes turn into a framework for how he really views science and reality.
and it’s even more than that.
those who know about such things know that the german armin hary is still the fastest man to 30m ever…and he had negro proportions…
the point is the very early part of a sprint is much more dependent on the brain and nervous system than the rest of it.
the boy named su is tied for 5th fastest time in the 60m ever.
he’s tied for 14th best at 100m.
why does it take you so long to post comments? my reasoning is because your social intelligence is either low or because youre a psychopath.
PP, could I induce you to estimate the I.Q. of Bobby Fischer (both at his peak and after the onset of his ‘illness’, assuming he really was crazy)?
Yes he would be a good one. I’ll discuss him before the end of February. He has a lot of high IQ correlates like chess rating, Ashkenazi ancestry, height, arguably extreme liberalism (even though it was a very politically incorrect liberalism).
I already estimated his I.Q., but I won’t tell you because I want to see how close our figures are without spoiling it.
You said Michael Jackson leaving money to his kids was an extreme act of conservatism because they aren’t black enough. Fischer was a hardcore antisemitic Jew. That is profoundly illiberal by your definition. I’ll read your post on him to see how you argue otherwise.
Black enough? They aren’t black at all, and I think at least one of them is Jewish. Antisemitism can be both liberal and conservative depending on the motive. When Jews are resented for supposedly pushing affirmative action and Third World immigration, that’s conservative, but when Jews are resented for running big banks & pushing neocon agendas, that’s arguably liberalism because liberals oppose social inequality and Jews are at the top of socio-economic hierarchies.
Pumpkin reads too much into things that maybe are there but no one would hundred percent claim to be their motivator.
there is a false belief that im acting unstable when in fact i am the most stable individual here. dont get your motives twisted people. have faith in what you know to be true and nothing else.
HALLELUJAH!
Accusing Jews of controlling money is liberal. That’s one I hadn’t heard before. Liberals don’t oppose social inequality; they oppose white goyim having power. That’s the whole point.
That’s the whole point of the media which has hijacked the liberal movement but true liberals are concerned about more than just demonizing white people. True liberals are very concerned about Palestinian rights for example.
Any modern “true liberal” mildly receptive to explanation for intergroup difference beyond white supremacy and misogyny is considered a Nazi enabler. Such people are becoming more and more rare as they defect to the aptly named right. You’re a de facto conservative (because you understand the nature of hierarchy and its implications) with an anachronistic conception of liberalism and emotional biases that prevent you from reconciling to HBD’s most significant corollary: modern conservatism.
I agree HBD is conservative and one of the reasons its conservative is it promotes inequality by blaming the disadvantaged (poor black women) for their own poverty and crediting the advantaged (rich Jewish men) for their own success.
By contrast anti-Semitism is arguably liberal because it blames the advantaged (rich Jewish men) for the problems of the less advantaged (working class whites). There’s a reason Nazis were called national socialists. Even anti-immigration can be considered liberal in the sense that immigration benefits the upper class at the expense of the underclass.
The reason for defining these views as liberal is it better fits with the fact that several super high IQ whites (Chris Langan, Bobby Fischer etc) are ant-semetic. If we call these high IQ men conservative, then they’re a pretty big exception to the fact that high IQ people tend to be liberal. So rather than argue the correlation changes at higher levels, one could just argue that liberalism itself changes at higher levels.
You’ve gotta get out of this “conservatism = worshiping power” thing. Modern liberals are the biggest bootlickers of all time. They’re usually just too stupid to see it. Most on some level believe a politburo of aristocrats and social scientists who spent 6 figs on book recommendations should tell the rest of mankind what to do.
Pumpkin “I make good use of the words I do know” Person:
Stop using that ancient definition and ascribing it to obvious right-wingers because they don’t like certain authorities. If you want to say “classical liberalism,” that’s more appropriate. Using “liberal” and “doesn’t like authority” interchangeably is anachronistic and insane.
Fischer is one of my heroes. I look forward to reading your upcoming post.
I recently estimated his I.Q.. Will be interesting to see how widely my figure diverges from yours.
Puppy estimate the IQ of a gorilla raised by a middle class family.
I actually will at some point. There’s been a lot of interesting research on this.
Remember the Sandy Hook shooter? He called in John Zerzan’s anarcho-primitivist radio show to discuss Travis the Chimp.
youre a fool Pill. with all the cognitive decline you went through as a schizophrenic i doubt you maintain an IQ over a hundred any more and your IQ might as well be retarded-functioning with the stupidity you bring to this blog.
Gorilla IQ >Loaded IQ
the only gorilla i can think of with a lower IQ than Koko might be Donald Trump your savior and hero who is so stupid he did not correctly calculate anything worthwhile and failed to factor in [redacted by pp. 2022-01-30]
You Pill are a cultist who worships orange clowns like him (he does indeed wear makeup) and classifies himself as being superior for such said stupidities.
Pill your ignorance is your curse and schizophrenia has blinded you from truth. come back to reality man. you are worshipping Boomers who had fucked their existences up before they could even walk!
Are you drunk? You have a very disordered mind.
how is any of that discorded? im naturally much more creative than you despite you having the schizophrenia advantage you are the least creative and most black-and-white mind i have ever met!
Here I estimated Koko had a verbal IQ of 23
https://pumpkinperson.com/2021/05/12/the-verbal-iq-of-apes/
monkeys probably have a higher nonverbal than even humans when verbal heuristics become dissolved from the human repertoire of ability.
a lot of nonverbal is basically manipulated by verbal ability. this is done to emphasize how people will conduct organized tasks in their mind!

Where my country gone?
I was playing Galactic Civilizations II last night when I got this technology discovery description, and I laughed my ass off because it’s basically my “optimize the genotype for I.Q.” idea
Pumpkinmeister you need to sell your blog to someone who can actually identify talent in your industry. right now it seems like the superstars of your blog are ill-fated for the future.
i now suspect you have both bipolar AND PTSD to go along with your suite of mental illnesses.
and this has happened. yet now british classism in the form of francis galton is used to excuse the jewish takeover of americastan and thw anglosphere in general.
and avoiding war is the excuse for the german takeover of europe. no afro. france is not germany’s consort. france is germany’s butt boy. just like hen hitler was alive. sad.
WHy do you keep saying Germany owns Europe. Germany is basically a severe cuck in Europe. They give money to every European country and apologise continuously for WW2. Its embarrassing.
neither you nor Pumpkin are politicians. only politics you both aware of are blog politics.
germany IS the economy.
stupid.
germany USES the rest of europe to keep its currency price low so it can keep on kicking the world’s ass.

guess who’s second?
japan!
https://en.wikipedia.org/wiki/List_of_countries_by_current_account_balance
seriously!
the idea that denazification is possible is an idea only some low IQ sociology professor could come up with.
germans are like if japanese people could think.
pill: germans aren’t conmen.
mugabe: that’s just what they want you to think. remember the “showers”?
you don’t get the point.
nazism and bolshevism were moments in the weltgeist which have been temporally superseded by neoliberalism…
hegel’s prediction is that because neoliberalism defines itself first against bolshevism and much more recently with wokeness against nazism that it too is a mere moment in the weltgeist. whatever defines itself as “not that” is not a lasting ideology.
and the next moment, the aufhebung, must affirm and at the same time reject all three ideologies.
a video example of what will happen to neoliberalism per hegel:
Loaded have you ever considered seeing a psychiatrist? You have a lot of neuroses from what I can see but maybe nothing clinical as yet.
Your biggest weakness is that youre a dumbass.
youre biggest weakness is that youre a conman who cant even get the job done properly.
*your
you have so many problems you cannot have an IQ of over a hundred id put money on that. you are a retard.
any semblance of reality you may hold is shattered daily its because you yourself are a dumb and arrogant prick!
PP will be interested in this article on the Rushton-Wilson relationship.
https://magazine.scienceforthepeople.org/online/the-last-refuge-of-scoundrels/
Looks interesting. Thanks for the link.
and if hitler said the sky was blue rr would say, “no it’s not racist!”
i read enough to see that the authors were dishonest and mentally retarded.
my guess is all wilson did was support flushton’s right to exist which totalitarian satansts like rr don’t.
rr wants to put all people who disagree with him in prison or in the ground.
he loves hitler and stalin and mao and pol pot.
only a totalitarian pos would even suggest banning IQ tests.
rr is too dumb to unnuhstan that he’d have to ban all tests.
so how would learning be assessed rr?
rr says, “wypipo all get Fs. black people all get A+s.”
i was thinking about rr’s low IQ and the low IQs of the authors of that article.
they literally can’t understand the difference between tolerating “racists” and the expression of ideas they label “racist” and tolerating actual racism, discrimination based on race. in fact they are so low IQ the call opposition to discrimination based on race (affirmative action) “racist”. they should move to north korea to experience actual racism for the first time in their lives.
