The following chart shows the results of the WISC-IV (UK version) given to several small samples of South African children (circa 2013):

Black Africa’s Wechsler full-scale IQ

Of the six demographic groups tested, the one most representative of black Africa would likely be disadvantaged black Xhosa speakers (DBXS) and these had an average full-scale IQ of 77.08 (UK norms).

However this number is likely an overestimate because the UK WISC-IV was nine years old at the time this study was published. Although I believe the Flynn effect is overestimated because of the kaufman effect and other methodological problems, Weiss et al., 2015 were able to sidestep these issues and show that at least from the 2000s to the 2010s, WISC-IV IQ increased by 0.31 points per year in the U.S.. Assuming UK norms became inflated at the same rate, DBXS have an adjusted IQ of 74.

Of course I realize the absurdity of using a sample of just 12 kids to represent all of black Africa, but it’s so rare to get a non-elite sample of black Africans taking a test as indepth as the Wechsler that I have little choice.

Black African Matrix IQ

Because the verbal subtests of the Wechsler require cultural knowledge that many black Africans have not been exposed to, people might think they would do better on a culture reduced test like the Raven Progressive Matrices. Richard Lynn however cited a series of studies showing black Africans did even worse on the Raven, averaging an IQ no better than 70.

However Wicherts et al,, 2009 accused Lynn of cherry-picking studies and argued that the true average Raven IQ of black Africa was 80. It is therefore interesting to note that on the matrix reasoning subtest of the WISC-IV, DBXS averaged an IQ equivalent of 83 (79 after adjusting for the Flynn effect).

Does this mean Wicherts et al. were right and Lynn was wrong? Probably not. The matrix reasoning subtest on the Wechsler has a test-retest reliability of around 0.66, while the Raven’s might be as high as 0.95. Taking the square root of these values tells us that matrix reasoning correlates 0.81 with true score while the Raven correlates 0.975.

What this means is that if the true score IQ of black Africans on this type of test is 31 points below the UK mean set at 100, they’ll score 31(0.975) = 30 points lower on the Raven, but only 31(0.81) = 25 points lower on the matrix reasoning subtest. The observed subtest score of 79 is not far from this prediction.

How would black Africans score on a truly culture reduced test?

The Raven is often described as a culture reduced test, however given the huge Flynn effect it has shown in some countries, many people are skeptical. One source of cultural bias might be exposure to columns and rows in school and media.

In my opinion, the most culture fair “verbal” subtest on the Wechsler is Digit Span and the most culture fair performance subtest is Block Design. Unlike Matrix reasoning, Block Design is a concrete task that is considered fun, and its fast pace makes it less dependent on culturally acquired values like persistence, cognitive confidence and intellectual discipline.

Thus, it’s interesting to note that after Flynn effect adjustments, DBXS averaged IQ 86 on Digit Span and IQ 80 on Block Design. Given the moderate correlation between these subtests, that works out to a composite IQ of about 80 which I take as a rough estimate for the real intelligence of black Africa.

Note, real intelligence should not be confused with genomic intelligence. Rather, real intelligence refers to a valid measure of the cognitive phenotype, but in the case of black Africans, the genotype is likely higher since even scores on the most culturally reduced tests can be depressed by sub-optimum nutrition and disease.

Because intelligence can be defined as the ability to adapt situations to your advantage, it’s only natural to expect smart populations to exploit less smart populations. In the extreme case this is known as slavery. For example, humans are smarter than animals and thus enslave horses, camels and other beasts of burden.

Thus if HBD is true, we should expect that among humans, high IQ races turn lower IQ races into beasts of burden, and indeed this has been a major theme of history. Caucasoids enslaved blacks, and among blacks, the Bantu enslaved the lower IQ pygmies. Meanwhile among Caucasoids, the high IQ Ashkenazim have arguably enslaved whites to the extent that they have tricked them into fighting Israel’s enemies for them in the Middle East.

There are exceptions though. Whites have higher IQs than Arabs yet Arabs enslaved whites. East Asians have higher IQs than whites, yet whites have never been enslaved by East Asians.

Aside from our enormous brains, it’s our ability to enslave other animals that most shows the supremacy of human intelligence. Thus among humans we should find that on average, big brained races are smarter than small brained races and that slave master races are smarter than slave races.

Of course some slave races are smarter than the very groups who enslaved them (i.e. whites vs their Arab slave masters ), and some smaller brained races are smarter than their bigger brained counterparts (high IQ Ashkenazim vs the big brained white race), however if my race not only enslaved your race, but ALSO has a bigger brain, I guarantee my race is smarter than yours AND that it’s genetic (on average of course).

The 20th century has been a period of great social change. Feminism, civil rights, gay rights, affirmative action, mass immigration, rock and roll, hip-hop, the welfare state, transgender people, secularism etc.

At first I thought all these changes were a sign of the Flynn effect. Better nutrition was increasing brain size, thus creating a smarter and thus more open-minded and tolerant society. However the rise in intelligence (and its correlation with social views) is way too small to explain such massive changes, especially since the Flynn effect has more to do with spatial ability than social and moral reasoning.

I then considered the Mug of Pee/Chomsky theory: Elites are focusing on identity politics as a divide and conquer strategy to keep the working class from uniting against the gazillionaires. But that theory failed to explain why this massive social change had occurred primarily in Western late 20th century environments. The rich have been thwarting the working class everywhere and always.

Finally I was forced to consider the alt-right theory that this massive social change is a deliberate attempt to replace whites with non-whites. I’m not normally one to indulge in conspiracy theories, but when a single theory unifies so many disparate facts, Occam’s razor demands we consider it.

When one looks at all the social changes of the last 50 years, what they all seem to have in common is the subversion of white population growth. Feminism gave white women careers, making them much less likely to have white babies. Civil rights, hip-hop, rock ‘n’ roll, and affirmative action increased the sexual market value of black men at the expense of white men, thus decreasing white male fertility.

The rise of gays, transgender people and securlarism gave millions of whites permission to abandon a traditional family lifestyle, thus damaging their genetic fitness.

Meanwhile, the welfare state encouraged poor women (who tend to be non-white) to have more children and mass immigration spread non-white genes into traditionally white countries.

But why would elites want to subvert white population growth? Perhaps because elites were persecuted by whites during Nazi Germany, and thus see them as a threat. Once these survivors of Hitler’s regime migrated to America as poor refugees, they used their high verbal IQs to achieve media and academic power and the wealth to buy politicians. But still lacking the power to challenge white dominance directly, they took the more subtle approach of changing the culture.
