The Black-White IQ Gap
3300 words
(This goes along with my refutation of Steele here: Strong Evidence, Strong Argument: Race IQ and Adoption)
There is a 15 point, 1 standard deviation between black and white IQs. I will argue that they are not biased towards any group, as well as there being both positive and negative life outcomes based on IQ, crime included. This is due to false ideas of equality, some “blank slate” idea that we all have the same capacity for cognitive ability, athletic ability and so on. These egalitarian ideas, in turn, have devastating effects on our society, as we a) deny the reality of intelligence and b) deny any type of racial gaps in intelligence.
The famous words “Compensatory education has been tried and has apparently failed” in Jensen’s paper in the Harvard Educational Review that reignited the firestorm on the race/IQ debate called How Much Can We Boost IQ and Scholastic Achievement? is the reason why this debate got thrown back into the public eye (Jensen, 1969). It will be argued in this paper that he was correct and that his main thesis that blacks need differing education than do whites is correct and needs to be done.
IQ tests were first developed off of Army Aptitude Tests in the early 1900s by French psychologist Alfred Binet. They were originally used to identify at-risk populations in terms of who is mentally retarded. People then say that due to this, that IQ tests don’t test anything of worth due to the reason why they were originally developed.
In 1976, a study was conducted called the Minnesota Transracial Adoption study where they took children of different races who were adopted into different families and tested their IQs at age 7 and again at age 17. A follow-up study was published in 1992. What was found, was that IQs of transracially adopted children didn’t differ at all from children raised by their biological parents in the same area.
Dr. David Duke states in his book My Awakening: A Path to Racial Understanding (1998), that the authors waited about 4 years to publish these findings. This, of course, has to do with the political climate of today. Any allegations of “racism” can and most likely will end someone’s career; so most individuals just go the politically correct route to play it safe and keep their credentials. Blacks raised in white families hardly did any better than blacks raised in black families. If the differences supposedly were environmental in the way environmentalists say it is, how come blacks raised in rich white families didn’t reach the IQ of whites if “IQ is malleable by the immediate environment?” Because the differences are genetic.
Though, there are other studies that state that environment matters more than genetic factors. These three studies (Moore 1986; Eyferth 1961; and Tizard, 1972) all conclude that the black-white IQ gap is environmental in nature.
A study was conducted that compared IQ scores of 23 7 to 10-year-old black children raised by middle-class white families and the same number of black children but raised in black families (normal adoption) (Moore, 1986). The findings indicated that traditionally adopted black children raised by black parents had normal IQ scores (85), whereas those black children who were adopted by white families had IQs 1 standard deviation (100) above the black mean. Moore states that multivariate analysis indicates that the behaviors of black and white mothers were different in regards to how the black children were treated. She states that white adoptive mothers reduced stress by joking, laughing, and grinning. Whereas black adoptive mothers reduced stress in less positive ways including coughing, scowling and frowning. She also says that white adoptive mothers gave more positive reinforcement to their adoptive child’s problem solving whereas black adoptive mothers gave less (as I am arguing here, these traits are mostly genetic in origin, driven by IQ). She concludes that the ethnicity of the rearing environment exerts a significant influence on intellectual ability as well as standardized test scores. The sample sizes, however, are extremely small and to infer that the black-white IQ gap is environmental in origin because of a study with a small sample size is intellectually dishonest.
One study conducted in Germany in 1959 observed IQ scores of out-of-wedlock children fathered by US soldiers stationed in Germany during WWII and reared by white German mothers (Eyferth, 1961). Mean IQ scores for 83 white children and 97 mixed-race children were 97, 97.2 for the whites and 96.6 for the mixed-race children (Rushton and Jensen, pg. 261). However, these results are disputed. One, the children were extremely young, one-third of the children in the study were between the ages of 5 and 10 whereas the remaining two-thirds of the children were between the ages of 10 and 13. The malleability of intelligence is very well-known in regards to children. The heritability of IQ at age increases with age (a phenomenon known as ‘the Wilson Effect’), which Arthur Jensen states that as a child ages, social environment can increase IQ (as heritability for children aged 5 is 22 percent and children aged 7 at 40 percent). Though, as the child ages, genes activate, and they fall to their genetic potential, with genetic effects accounting for a lion’s share of intelligence (80 to 90 percent) and environment having no effect. Second, 20 to 25 percent of the ‘black’ fathers were French North Africans (Caucasians). This shows why the mixed-race children had higher IQs in the sample: about a quarter of the sample was Caucasian (Rushton and Jensen, pg. 261). Finally, rigorous selection was done on both the white and black soldiers. With 3 percent of whites getting rejected compared to 30 percent of blacks, it is shown that high IQ blacks were selected for, therefore, skewing the sample.
Yet another study on black and white children observed 2 to 5-year-olds in a nursery setting (Tizard, 1972). The white and black children both had IQs at 102.6 and 106.3 respectively. She found no significant gap in the three groups tested (white, black and West Indian). However, she did note that the single significant difference was in that of non-white children.
All three of the above studies that get cited ad nauseum have something in common: they did not retest the children again at age 17 like was done in the Minnesota Transracial Adoption Study. This is very critical. As it was alluded to earlier, as children mature, genetics exerts more of an effect than does socialization. Any IQ differences that are brought about by socialization will be mediated by genetics at adulthood, falling to the racial mean. It also noted how the age of adoption does not influence children’s IQ scores after age 7 (Jensen 1998b). This is due to, again, genetic effects being heightened as age increases.
What the Minnesota Transracial Adoption Study (Weinberg, Scarr, and Waldman, 1992) and the Eyferth study (1961) had observed was that the children born to a white mother and a black father had statistically significant differences in IQ in comparison to those birthed by a black mother and white father. This is attributed to prenatal environment. It was observed that mothers who had higher IQs and were more educated (which both correlate highly with each other), had children which, in turn, had higher IQ scores as well (Erikson, 2013). The results of the study suggest that mothers who are more educated have children who have higher intelligence. This should end this debate right there. Since, clearly, a white mother is more conducive to foster a higher IQ than is a black mother, this shows that racial differences in IQ are largely genetic in origin.
The black-white IQ gap has been noticed for over 100 years, ever since the test has been first conceptualized. Egalitarians may say that “they’re biased against minorities” or “they don’t learn the right things on the test”, all of these are easily refutable. This was true in the 70s, according to Herrnstein and Murray, but today there is no bias of that magnitude on these tests of cognitive ability.
Jensen states that genetic and cultural factors influence the black-white IQ gap the same as individual factors (80 percent genetic factors, 20 percent environmental). Since both individual differences in IQ, as well as the mean difference in the black-white IQ gap are genetic, this shows that some individuals are genetically predisposed to have lower IQs. Moreover, a multitude of traits in life fall on a bell curve, you will have some individuals at one end, and others at the opposite end, but you’ll see a majority fall in the middle of the racial mean (85 for blacks, 100 for whites, 104 for East Asians and 107 for Ashkenazi Jews). So, with equalized environments, the gap can be closed by around 3 points, but still a lion’s share of the gap is still there, which again gives credence to the genetic hypothesis.
Those who disbelieve the validity of IQ tests at the individual level, as well as the between-group level, say that test biases are the cause for lower scores in certain individuals in minority populations. Gottfredson et al state in their publication that was released after the controversial book The Bell Curve, Mainstream Science on Intelligence, that if you speak the language, IQ tests are not biased. If you don’t speak the language, you then get a special IQ test that is culture free, based on pattern recognition called Raven’s Progressive Matrices. Even then on these culture-free, word-free IQ tests, there is still a one SD gap, 15 points, between blacks and whites.
People have tried to bridge the gap, even going so far to make a test that’s ‘culture fair’ to blacks called the B.I.T.C.H. (Black Intelligence Test of Cultural Homogeneity) IQ test (Williams, 1972). What was found was that blacks scored highly, whereas whites lagged behind. But, the thing is, this test has ridiculous concepts that don’t test actual intelligence. The way that people say that regular IQ tests are biased towards blacks don’t even realize that the way the B.I.T.C.H. IQ test is set up does not mirror the supposed biased nature of regular IQ tests on blacks.
Flynn noticed that no matter which country you look IQs have gained around 3 points per decade. Herrnstein and Murray then coined the term The Flynn Effect, after the man who focused the most attention on the phenomena. Flynn argues that since IQ scores have been gaining the same amount of points in any population no matter where you look, that the black-white IQ gap has to be environmental in origin.
However, the Flynn Effect is a fallacy and is overstated. In 1945, the average IQ of whites in America was 85, the same as the black average today. That statement is supposed to show that the between-group differences are environmental in origin and since there haven’t been any big genetic changes in both populations to account for this difference, then the gap must be environmental in origin. Just because a change in one group over time is due to an environmental change, doesn’t mean, or even make it probable, that a difference between 2 groups at the same time is due to an environmental change. The Flynn Effect make’s that highly unlikely and here’s why.
Any country you look at, the rate of increase is 3 IQ points per decade; but gaps in IQ stay the same. This shows that this same uniform factor affects all groups the same throughout the world. And due to this uniform factor, as a result, you have a difference in IQ that’s being preserved. This suggests that the response on the parts of blacks and whites is due to non-environment factors, a genetic factor, which makes the difference in IQ remain as the Flynn Effect goes into effect.
Blacks and whites also have a similar environment, especially since segregation ended. Since environments are similar, the more and more similar the environment, the less and less differences are due to environment and the more and more they are due to genetic factors. So the 15-point gap surviving this change in environments proves that the racial gap is genetic in origin.
Dickens and Flynn state that black Americans have closed the gap in recent years, but this, however, is not the case. Most of those studies were done on children; Jensen states that the black-white IQ gap becomes more noticeable as they get older because genetic effects take over at adulthood with the environment having little if no effect on IQ (Rushton and Jensen, 2005). Jensen concludes that the SD gap between blacks and whites at early adulthood is about 1.2 SDs or about 17 IQ points. In Rushton and Jensen’s 2005 paper, Flynn and Dickens sidestepped a theoretical analysis in which it’s showed that the higher amount of white admixture a black has, the higher his IQ score is.
The Flynn Effect is not on g, or the general intelligence factor, which the most heritable items on the subtests show the most differences between blacks and whites (Rushton and Jensen, 2010). Since the Flynn Effect does not fall on g, this should not even be in the discussion. A Flynn Effect is not a Jensen Effect, which is real gains in g over time (Rushton, 1998). Rushton found it ridiculous that we had a nation of mentally handicapped children 100 years ago. This was enough for him to disregard the Flynn Effect.
Other proposed causes for this gap involve a mechanism called ‘stereotype threat’ (Steele and Aronson, 1995). Stereotype threat is a situational predicament in which people find themselves falling into the stereotype of whatever group their group is a part of. Though, this is not the case for blacks. Blacks are rated as seeing themselves as more attractive, which a) shows more self-confidence and b) shows that the so-called effects of white racism making blacks feel ugly and inadequate in their own skin are simply not true. Kanazawa (2011) noted that both male and female blacks rated themselves higher than other groups; showing that there are no lingering effects of racism as well as this silly belief that just by thinking you’re going to fall into a stereotype means that you will fall into it.
Still, others may state that poverty is a cause for the IQ disparity between the races. People have causalities mixed up when they make this statement. Since lower IQ is correlated with lower SES, the cause of poverty is people being born with low intellect which manifests itself in the wealth attainment of the individual. Many recent studies have come out saying that poverty decreases IQ, yet the only environmental factors that can do such a thing is malnutrition, extreme abuse, and extreme isolation. Other than that, all a parent needs to do is just give the child an ‘OK’ environment and genetic factors will take care of the rest.
Critics of the public school system have said for decades that you can’t solve educational problems by throwing money at them, but those who believed in the public schooling system said it has yet to be tried. They did try, in Kansas, MO, and failed miserably (Ciotti, 1998). This desegregation experiment cost 11,700 dollars per student, more money spent per individual on a cost of living basis than 280 school districts around the country. This tax-payer money bought “higher teachers’ salaries, 15 new schools, and such amenities as an Olympic-sized swimming pool with an underwater viewing room, television and animation studios, a robotics lab, a 25-acre wildlife sanctuary, a zoo, a model United Nations with simultaneous translation capability, and field trips to Mexico and Senegal. The student-teacher ratio was 12 or 13 to 1, the lowest of any major school district in the country.”
Despite all of these variables to enrich the environment of the black students, even bussing in white kids from out of district, the gap did not diminish, test scores did not change and there was less, not more, integration. Moreover, numerous individuals say that poverty and schooling systems are the cause for anti-intellectualism in the black community. I, however, argue that there is a considerable genetic component to the black-white IQ gap (Rushton and Jensen, 2005 p. 279).
Where does all of this leave us? Yes, blacks are less intelligent than whites, but what does this mean for our society that we refuse to acknowledge the existence of innate intelligence, as well as racial differences in intelligence? The average IQ of a repeat juvenile criminal in America is 92 (Herrnstein, Murray, and Cullens, 1998). At adulthood, the average IQ for a repeat criminal is 85. The reason for the IQ of a repeat adult offender being lower than that of teenaged offenders is due to as you age, the environment doesn’t matter as genetics takes over at adulthood.
The fact that we are disregarding g (intelligence) and its multiple covariates is extremely alarming. The fact that America is headed down the path to dysgenesis (Lynn, 2006) and we are not doing a thing about it troubles me greatly. The way we treat black underachievement in America is completely wrong. To succeed as a country, we need to recognize biological truths in that certain groups achieve highly whereas others have low levels of academic achievement, we need to recognize that there is no insidious plot to hold down others; we need to realize that some groups are less intelligent as others due to evolution in differing climates over tens of thousands of years. The trillions of dollars we have spent on all of these programs have not worked. We have tried them, and they have failed. No matter what we do, black underachievement will always be around. By recognizing black underachievement, they will be better able to succeed relative to themselves and not compare themselves to other high-achieving groups. There is a considerable genetic component to the gap (80 percent genetic) and that due to this, blacks should have differing standards in comparison to the rest of the population (Jensen, 1969).

In Defense of Jason Richwine
3900 words
I came across two articles today, one from The Atlantic and the other from judgybitch.com. Both have attacked Jason Richwine’s dissertation in which he calls for a change to the US immigration policy to turn away low IQ immigrants and only accept high IQ ones. I agree fully with this (if it’s completely controlled, of course). This would drop crime as well as save us more money in welfare and other government programs that low IQ peoples take.
By 2050, 9 out of 10 people in the US will be obese or overweight and by 2020 80 percent of US men will be obese or overweight. This is due, in part, to an influx of those with lower IQs from South of the Border. Jason Richwine’s argument for testing immigrants will, in turn, lower obesity rates in America.
Dr. James Thompson noted how continued mass immigration from the South of the Border would decrease IQ, this is a real and pressing issue. A country is only as good as its majority population and by allowing all of these low IQ people into the country, our country will transform into theirs, which is ironic since that’s the exact thing they’re running away from. You cannot run away from genetics. The overall ‘Hispanic’-white gap is 10.2 points or .72 SDs. That will lower the average IQ of the country even more, and in turn, give us all a lowered quality of life. The average IQ of Mexico is 88 (Lynn and Vanhanen, 2002) so by allowing unfettered mass immigration without checking average IQs to see if they’ll be of any use to us as a country will lead to eventual irreversible effects if this isn’t stopped soon.
The first article I’ll look at is the one from The Atlantic:
Let’s start with the fact that there is no such thing as a direct test of general mental ability. What IQ tests measure directly is the test-taker’s display of particular cognitive skills: size of vocabulary, degree of reading comprehension, facility with analogies, and so on. Any conclusions about general mental ability are inferences drawn from the test-taker’s relative mastery of those various skills.
IQ tests test g or the general intelligence factor which encompasses all mental abilities. I guess the author of this piece has never heard of Raven’s Progressive Matrices. It’s a ‘culture free’ IQ test where the test is based on pattern recognition. No bias there.
Even then, if they don’t speak English and speak Spanish, they can get tests in their native language which are not biased. Gottfredson (1994) and 51 other eminent intelligence researchers signed a 25 point statement in which one of the statements was:
Intelligence tests are not culturally biased against American blacks or other native-born, English-speaking peoples in the U.S. Rather, IQ scores predict equally accurately for all such Americans, regardless of race and social class. Individuals who do not understand English well can be given either a nonverbal test or one in their native language.
They will be given the nonverbal test (RPM, see below) or one in their native language, which still test the same underlying concept of the general intelligence factor.
They found that being raised by high-SES (socioeconomic status) parents led to an IQ boost of between 12 and 16 points – a huge improvement that testifies to the powerful influence that upbringing can have.
False. See below.
A study of twins by psychologist Eric Turkheimer and colleagues that similarly tracked parents’ education, occupation, and income yielded especially striking results. Specifically, they found that the “heritability” of IQ – the degree to which IQ variations can be explained by genes – varies dramatically by socioeconomic class. Heritability among high-SES (socioeconomic status) kids was 0.72; in other words, genetic factors accounted for 72 percent of the variations in IQ, while shared environment accounted for only 15 percent. For low-SES kids, on the other hand, the relative influence of genes and environment was inverted: Estimated heritability was only 0.10, while shared environment explained 58 percent of IQ variations.
Turkheimer was right that he did find gene x environment interactions that made genetic influences weaker and shared environment stronger for those from poorer homes in comparison to those from more affluent homes. Though most studies show no interaction effects, or interactions vary significantly.
Other studies have shown that heritabilities are the same both within as well as between white and black samples. That led Jensen to label this the ‘default hypothesis’. Researchers analyzed full and half siblings from the NLSY on three Peabody Achievement Tests. 161 black full siblings, 106 pairs of black half siblings, 314 pairs of full white siblings and 53 pairs of white half-siblings. with measures in math and reading. The best fitting model for all of the data was by which the sources of the sources of the differences between those within race and the differences between races were the same, at 50 percent genetic and environmental. The combined model (50/50) best explains it, whereas the culture-only and genetics-only models are inadequate.
IQ tests are good measures of innate intelligence–if all other factors are held steady.
This is wrong. IQ tests are fine all around the world. RPM is one of the best out there and correlates with g between .8 and .9.
But if IQ tests are being used to compare individuals of wildly different backgrounds, then the variable of innate intelligence is not being tested in isolation. Instead, the scores will reflect some impossible-to-sort-out combination of ability and differences in opportunities and motivations. Let’s take a look at why that might be the case.
Intelligence – g – is the same across every population in the world.
Comparisons of IQ scores across ethnic groups, cultures, countries, or time periods founder on this basic problem: The cognitive skills that IQ tests assess are not used or valued to the same extent in all times and places
This is why they get re-standardized.
Indeed, the widespread usefulness of these skills is emphatically not the norm in human history. After all, IQ tests put great stress on reading ability and vocabulary, yet writing was invented only about 6,000 years ago – rather late in the day given that anatomically modern humans have been around for over 100,000 years. And as recently as two hundred years ago, only about 15 percent of people could read or write at all.
Doesn’t matter. See Raven’s Progressive Matrices above. The general intelligence factor is the same in all populations around the world. There are ways to give intelligence tests, such as RPM, to those who don’t read or write.
More generally, IQ tests reward the possession of abstract theoretical knowledge and a facility for formal analytical rigor.
Abstract thought is linked with intelligence. Those with higher IQs are more analytical than those with lower IQs.
To grasp how culturally contingent our current conception of intelligence is, just imagine how well you might do on an IQ test devised by Amazonian hunter-gatherers or medieval European peasants.
I touched on this in my refutation of Robert Sternberg. The concept of g does not change over time. The more intelligent you are, the better chance you’ll have to survive in those places.
Such skills are used more intensively in the most advanced economies than they are in the rest of the world. And within advanced societies, they are put to much greater use by the managers and professionals of the socioeconomic elite than by everybody else. As a result, American kids generally will have better opportunities to develop these skills than kids in, say, Mexico or Guatemala. And in America, the children of college-educated parents will have much better opportunities than working-class kids.
Those skills are used much more in advanced economies because of higher average innate intelligence. The children of college-educated parents have much better opportunities than working-class kids because intelligence is strongly linked to socioeconomics status.
Among the strongest evidence that IQ tests are testing not just innate ability, but the extent to which that innate ability has been put to work developing specific skills, is the remarkable “Flynn effect”: In the United States and many other countries, raw IQ scores have been rising about three points a decade. This rise is far too rapid to have a genetic cause. The best explanation for what’s going on is that increasing social complexity is expanding the use of the cognitive skills in question – and thus improving the opportunities for honing those skills.
Let’s say Flynn is right. The average black now is as intelligent as the average white in 1945. That’s supposed to show that the race difference in IQ is environmentally caused because there hasn’t been that much genetic change in the white population and the IQ has allegedly gone up 15 points. So, you can have a 15 point difference created by just an environmental change, no one knows why. Some think better nutrition or malnourished brain, etc. That’s also a fallacy. Just because a change in one group over time is due to an environmental change, doesn’t mean, or even make it probable, that a difference between 2 groups at the same time is due to an environmental change. The Flynn Effect make’s that highly unlikely and here’s why.
The Flynn Effect, assuming it’s real, has been acting completely uniformly in every population. Any country you ask, the rate of increase is 3 per decade. That means it’s an environmental factor that affects whites and blacks the same way as well as the whole world. And as a result of this uniform environmental factor, you have a difference in IQ that’s being preserved. That would suggest that the response on the parts of blacks and whites is due to some non-environment factors, a genetic factor, which is making the difference in IQ remain constant as the Flynn Effect goes into effect.
What makes it even more unlikely, in the last 60 years, their environments have become very similar since segregation. These differences don’t exist now, they go to the same schools by court order, same TV shows, same movies, basically same environment for both, and yet, that increasing similarity in the environment, the Flynn Effect, the IQ gap has remained intact. Which means whatever counts for the gap is genetic and not environmental. The more and more similar the environment, the less and less of the difference can be due to the environment and the more and more it must be due to genes. So this 15 point gap surviving these changes in the environment, seems more and more likely to be genetic in origin.
So because this ‘Effect’ is the same across all populations and the gap didn’t close, that means it’s genetic. If the gap persisted even when IQs were rising 3 points per year, the B-W gap has still persisted, proving that it’s genetic.
That is why the Flynn Effect is irrelevant. This “Effect”, has been a slight upward trend in IQ, around 3 points per decade, which, in my opinion, has to do with the advent of better nutrition and an industrialized society. The rise in IQ started around 1880, almost perfectly coinciding with the industrial revolution in America. Along with a more industrialized society, it’s possible to give most citizens in the country good enough nutrition to where they are not iodine deficient (adding iodine to our salt boosted Americans IQs), as well as being deficient in zinc, iron, protein and certain B vitamins which the effects of not getting enough leads to the brain not growing to its full potential, which in turn leads to a lower IQ.
One more point on the Flynn Effect. The Flynn Effect does not occur on g, as it is not a Jensen Effect. Rushton defines Jensen Effect as follows:
Significant correlations occurring between g-factor loadings and other variables have been dubbed “The Jensen effect”.
…
Thus the secular increase in test scores (the “Lynn±Flynn effect”) is not a “Jensen effect” nor is this the first time the discriminating power of the Jensen effect has been shown.
The Flynn effect is acutely embarrassing to those who leap from IQ score differences to claims of genetic differences in intelligence.
Not at all, since it’s easily explainable by better nutrition since the beginning of the industrial revolution. It’s also not even on g so why this gets discussed is beyond me.
Specifically, it is based on the ahistorical and ethnocentric assumption of a fixed relationship between the development of certain cognitive skills and raw mental ability. In truth, the skills associated with intelligence have changed over time–and unevenly through social space–as society evolves.
The relationship exists and there is a strong correlation between cognitive skills and raw mental ability. More intelligent people have better functioning societies than less intelligent people. This is an objective fact.
But contrary to the counsel of despair from hereditarians like Richwine, those deficits aren’t hard-wired. Progress in reducing achievement gaps will certainly not be easy, but a full review of the IQ evidence shows that it is possible. And it will be aided by policies, like immigration reform, that encourage the full integration of Hispanics into the American economic and cultural mainstream.
Jason Richwine is correct. Progress in achievement gaps will not close, barring the continued dysgenesis that America is facing. Immigration reform will not change anything. They don’t want to assimilate; they want to come and leech off of our Welfare State. The denial of genetics and scholastic achievement won’t be able to be held for long. In this study in which Robert Plomin was one of the researchers, it was found that 60 percent of the difference between individual 16-year-old students in the UK could be attributed to genetic factors. We know that IQ is linked to academic achievement and since that’s heritable as well, we will soon see that race and ethnic differences in IQ and academic achievement are, without a shadow of a doubt, are real and do not exist because of any economic deprivation or some other kind of non-biologic factors.
For the second article, from judgybitch.com, in which she only says one correct thing in it and it’s:
Here’s a little pet theory of mine I’d like to throw out, just for the hell of it. I think humans prefer lighter skin and hair and eye colors because those tend to be the result of recessive genes. A man with darker tones who has a child with a woman of lighter tones will almost always see his genes expressed in the children. Dark tones tend to be dominant. The preference for lighter skin is a natural paternity test.
This is called sexual selection, which is natural selection which arises for selection of traits in the opposite sex. Selecting for certain traits which the opposite sex found appealing, for example, is how long hair got sexually selected for outside of Africa along with selection for hair, eye, and skin color. Selecting for these traits had them become more prevalent and they eventually stayed due to intense selection for them.
For example, Eurasian women got selected for beauty and Eurasian men who got selected for intelligence as men had to be more intelligent in order to hunt for food. Conversely, African women gathered and hunted for food and became slightly more intelligent than African men who became the more attractive sex (Fuerle, 2008).
But other than this she is wrong.
You know what IS linked very strongly to lower IQs?
Malnutrition.

http://www.nature.com/pr/journal/v5/n11/abs/pr1971371a.html
The idea is not even the slightest bit controversial. Children who are starved, especially in the earliest years of life, perform very poorly on IQ tests compared to peers who received adequate nutrition. Like, really poorly. IQ’s down around 60 (100 is average).
Let’s look at this world hunger map, shall we?
http://www.geographictravels.com/2008/07/world-hunger-map.html
Oh well now, would you look at that. Looks like it’s mostly black and Hispanic folks who are starving. And all those white folks are living life to the hilt, with full bellies and bright futures.
Must be a coincidence.
It’s not a coincidence. There is no coincidence that if you superimpose an IQ map over the world hunger map, that a super majority of the low IQ countries would have bad nutrition and be starving, whereas those higher IQ populations would have better nutrition and, therefore, higher IQs and lack of malnutrition and starvation. There are environmental factors involved in this, which I have gone through in my article IQ, Nutrition, Disease and Parasitic Load. Yes, those environmental variables decrease IQ; but in the case of Africa, if their full genotypic IQ were expressed in their phenotype, they would have an average IQ of 80, 9 points away from the lowest average European country which is Serbia at 89. They would then be able to have better functioning societies and not have to rely on outside aid. Though, their low IQs are the cause of evolution, those factors only cause about 10 points of difference (depending which of the variables I mentioned exist in those areas).
Let’s look at this map of food insecurity in the United States:
http://www.nextgenerationfood.com/news/food-insecurity-in-the-us/
Highest rates of food insecurity:
Mississippi
Texas
Arkansas
Lowest rates of food insecurity:
North Dakota
Massachusetts
Virginia
Gosh, I wonder where all the black and Hispanic people are? North Dakota, right?
According to the USDA, in a report titled Household Food Security in the United States in 2011, black and Hispanic families are more than twice as likely to experience food insecurity as white families (p. 11).
White 11.4% of families food insecure
Black 25.1%
Hispanic 26.2%
Gosh, I wonder where black and ‘Hispanic’ people are? Mississippi, Texas, and Arkansas right? What is the cause of the food insecurity? Lower intelligence. What is lower intelligence highly correlated with? Obesity.
If you keep in mind the fact that obesity (especially as the result of heavily processed, nutrient deficient junk foods) is also a form of malnutrition, it seems to me that there is an entirely different explanation for why certain racial groups might tend to perform lower on IQ tests.
Sure it is. A big cause for obesity is lowered intelligence (Kanazawa 2007). What he found was that those studies that concluded that obesity causes lowered intelligence only observed cross-sectional studies. Longitudinal studies that looked into the link between obesity and intelligence found that those who had low IQs since childhood then became obese later in life and that obesity does not lead to low IQ. The average IQ for an individual suffering from PWS is 65 (Butler, Lee and Whitman 2006, p. 13), so that is one reason they have a tendency to be obese. He states that those with IQs below 74 gained 5.19 BMI points, whereas those with IQs over above 126 gained 3.73 BMI points in 22 years, which is a statistically significant difference. Also noted, was that those at age 7 who had IQs above 125 had a 13.5 percent chance of being obese at age 51, whereas those with IQs below 74 at age 7 had a 31.9 percent chance of being obese. This clearly shows that those obese individuals who score low on IQ tests, more often than not, are obese because of their intelligence. The lack of ability to delay gratification is also correlated with low IQ (Mischel and Metzner, 1982).
Becoming obese is largely in part related to environmental factors, but there are correlates with obesity and genetic factors, as well as racial and ethnic differences in obesity, which are due, in part, to environmental as well as genetic factors. All of these factors fall back to a) lower intelligence, b) differing physiology and c) differing nutritional habits. Lower IQ is the main reason, though, for these differences which manifest itself as differences in scores of cognitive ability. Those with lower scores than have higher chances of having negative effects in life, such as low SES, higher chance of becoming obese and so on.
Correlation is not causation.
This is the liberals word phrase they use when they cannot contest data and know it so use the same old boring phrase. When you get the same result over and over using the scientific method, then it’s safe to say that the same results and conclusions that get brought up time and time again are real and cannot be explained away by the correlation does not mean causation line.
And furthermore, I haven’t read Richwine’s dissertation, nor do I plan to, so I don’t know if he offered any tentative explanations for his findings.
Didn’t even read it and is giving a critique of it. How does that work?
It looks to me like Richwine is a gigantic racist asshole, because he is using his findings to try and limit the opportunities for Hispanic people to come to the United States, because dumb spics.
Lower IQ people commit more crimes than do higher IQ people. This phenomenon is well-noted that those with lower intelligence commit crime, as the average IQ of a criminal in America, is 85, whereas the average IQ for a juvenile is 92. The average juvenile IQ is higher because more often than not, those who are habitual offenders in childhood become habitual offenders in adulthood, and at adulthood IQ drops from childhood where the environment was able to artificially boost their IQs.
What if I’m right? What if IQ differences are traceable to malnutrition? That would indicate a whole different set of interventions and policies than just turn them away.
You are part right, but that won’t put any big dent in any genetic/phenotypic IQ differences and still, mass immigration from South of the Border still wouldn’t be OK in the first place.
In shutting down the conversation about race and IQ, Harvard students are explicitly saying they don’t WANT to find a reason behind low performance on IQ tests amongst certain racial groups. They don’t CARE why some groups are not reaching their full human potential. They don’t give ONE SINGLE FUCK about anyone other than themselves. It could be as simple as making certain children have access to proper food and nutrition.
I at least give her credit for acknowledging the biological reality of race and the reality of IQ. But she thinks that malnutrition plays too big a part in the ethnic IQ gap than it does in reality.
As I have covered here before, people will do anything they can to deny the validity of IQ tests. However, their explanations cut it.
People who attempt to deny biological differences in intelligence because they strongly predict positive life outcomes will do anything to deny their validity. But that doesn’t change how strong a predictor they are in regards to predicting both positive and negative successes in life.
Those who attempt to deny any differences between races, like Chanda Chisala (I know you can see this Chanda, still waiting for a response to the criticism of your horrible article that “redneck genes” are the cause for the black-white IQ gap), who are wrong in their premises on the cause as well as how to fix the gap. They will do anything to attempt to explain away a gap which is, at least, 50 percent genetic in origin.
The attack on Jason Richwine is because, of course, he’s right. They don’t want to admit he is right so they do whatever they can to discredit his argument, by calling him a ‘racist’. But that doesn’t negate his data, and as seen above, any arguments against Richwine’s dissertation are unfounded.
Germany is going to begin IQ testing their immigrants, why can’t we?
Differential K Theory, GFP, and the Evolution of Conscientousness
There is a link between higher IQ and higher ability to be more conscientiousness, which is then linked to the GFP or General Factor of Personality. Two meta-factors were identified beyond the Big Five Personality Traits and were described as ‘Plasticity’ and ‘Stability’ (Deyoung et al, 2002). To quote from the paper:
Stability subsumes Conscientiousness, Emotional Stability (the reverse ofNeuroticism), and Agreeableness, and refers to the extent to whichan individual is consistent in motivation, mood, and social interac-tions. Plasticity encompasses Extraversion and Openness to experi-ence, and refers to the extent to which a person actively searchesfor new and rewarding experiences, both intellectual and social.
Why did this evolve, especially so closely with high intellect? It evolved due to conscientiousness, which is defined as being thorough, careful, and vigilant.That, coincidentally enough, being needed to survive the harsh winters of Northern Europe and Siberia. Higher conscientiousness was is also another reason for the formation of European societies. With being able to be more conscientious, this, along with genetic pacification, is yet another cause for the cucking of Europe.
When our ancestors trekked out of Africa and into Siberia and Northern Europe, they needed differing abilities than those peoples who stayed in the more tropic climates. Those in the tropics, for the most part, could just lounge around all day. With food being readily available, there was really no pressing need to “save” or “partition” their findings (as Africa is full of mostly a hunter-gatherer societies). Conversely, in Europe and Asia, with harsh conditions in regards to their environment, which made food less plentiful than in the tropics, this meant that more cooperation was needed. Due to more cooperation being needed to survive, planning ahead (abstract thought) evolved to better help cope with the harsh environment.
The aforementioned factors in Europe and Asia then led to the higher rates of altruism seen today. Ancient Europeans needed to be thorough, vigilant and careful. Whether they needed to be careful with food storage, how much to eat, whether or not to help someone, etc, it’s clear that conscientiousness evolved with higher intelligence. Since higher intelligence is correlated with those three things involving conscientiousness, they evolved hand in hand, as selection only selects for good traits and discards the ones that aren’t useful.
These two environments that the three races evolved in then set the stage for what’s going on today. With Africans’ lack of conscientiousness, this leads to them not being vigilant, careful or thorough. This can be seen with how sloppy they are when they commit crimes. Their ancestral environment wasn’t conducive to conscientiousness, and in turn, higher IQ, so they evolved without the need of conscientiousness, as their societies (for what they are), function ‘well’ in their perception. This is yet another reason why that we cannot live together. Differing evolutionary strategies lead to these causes, yet we still think we can acclimate some peoples into society when their biology says otherwise.
JP Rushton proposed that the GFP (General Factor of Personality) and IQ were linked. It was found that the correlation between the GFP and IQ was -.23. The higher the g score, the higher the individual scores on the GFP. He noted that the correlation is so low, possibly due to the restricted range of the sample. Rushton provided an argument for the evolutionary process of cognitive ability and personality evolution. This is clear evidence of the GFP and IQ evolving hand-in-hand.
Lacking a high IQ, and therefore, lack of g, Africans (as well as other colored peoples), on average, have lower g and therefore lower conscientiousness, which then is a huge cause for crime. Increases criminality has been correlated, like I’ve said here before, to a lower verbal intelligence. Though this higher IQ and higher GFP is being taken advantage of. Ever since that fateful day in 1964, white pathological altruism has been taken advantage of. Those with lower conscientiousness know they can take advantage of those with higher IQ and higher conscientiousness as altruism is correlated highly with IQ and conscientiousness.
There is an altruistic personality; the altruist has a high IQ, is conscientious, and altruistic. Those on the opposite end of the spectrum, however, take advantage of that and this can be seen with the political climate around the world in regards to other races’ feelings towards whites.Conversely, those who are r-selected and have a low IQ and GFP tend to be more hostile and commit acts of aggression. This multiculturalism due to the altruistic personality on a large scale is one of the reasons for the mass immigration into Western societies. People, as a whole, become collectively altruistic. Then, those lower IQ, lower GFP, r-selected people then take advantage of the more altruistic people. They then turn into a parasitic entity, sucking the host dry before moving on to their next victim.
This is where a high GFP does not work, in multicultural societies. Of course, this is also due to ethnic dissimilarity, but the other thing I brought up along with that ethnic dissimilarity are all of the negative effects of those that are r selected, which, in their own societies is ‘fine’, but to who are K-selected and have complex societies, those behaviors are archaic.
There is a high correlation between low IQ, low conscientiousness, archaic actions, lack of abstract thought, and lack of society building. We know that those with lower IQs commit more crime on average than those with higher IQs.
This is why allowing non-Western people who are abnormal to our societies is a bad move, since they don’t share the same evolutionary track, and therefore, due to differing selections due to evolution, evolved differing behaviors to better adapt to the climate, environment, and surroundings.
Since skin color and IQ correlate at -.92, meaning the darker the skin the lower the IQ and vice versa, this is yet another great assessor on whether an individual has a high IQ, and is, therefore, conscientious. This is due to, as I alluded to earlier, the environment in sub-Saharan Africa being conducive to lack of ability to delay gratification. Due to that, we can infer, on average, whether someone will be conscientious or not. Since their ability to delay gratification is impeded due to certain evolutionary pressures not put on Asians and Europeans, they will, therefore, be less conscientious, which is a crucial building block in maintaining a successful society.
The research of Templer and Arikawa (2006) supports Rushton’s contention that higher intelligence develops in colder climates. They used 129 countries with primarily indigenous populations (Asia, Africa, and Europe) and correlated culture fair IQ (Lynn & Vanhanen, 2002) with temperature. In addition to temperature, Templer and Arikawa used skin color provided by an anthropology book (Biasutti, 1967). IQ correlated .92 with darker skin color, .76 with winter highs, .66 with winter lows, and .63 with per capita income. Previous research by Meisenberg (2004) reported a correlation of .89 between skin reflectance and IQ in a similar study. Templer (2010b) found a correlation of .96 between skin color measure used by the Templer and Arikawa and the one by Meisenberg’s skin reflectance. Because both measures were independently determined using different methodology, they both can be regarded as highly valid measures of skin color.
The cause of these two variables being correlated is evolution. They paired well with each other, so over tens of thousands of years, they got selected for with each other and persisted to today. Since we have modern societies and are much more civil (some of us), we can better see these differences in personality as well as behavior. There are This General Factor of Personality was able to evolve due to evolution in cold climates. The altered intelligence, which then altered personality. This r/K Life History Theory of Rushton’s blend’s beautifully with the GFP and intelligence. Evolution in cold climates along with genetic isolation caused differing evolutionary trajectories for each race/ethnicity which led to differences in crime, IQ, socioeconomic status, sexual maturity, cultures, and so on. There are clear genetic differences brought on by the environment (due to evolution), which leads to differing societies based on differing evolutionary trajectories. Conscientiousness and intelligence, the whole General Factor of Personality, evolved in Northern populations since it was more beneficial in that environment, and to survive, this is what done to adapt to the environment through natural selection, which then led to racial differences.
Germany Begins to (Slightly) Wise Up: Will Begin IQ Testing “Migrants”
800 words
Haaretz reported today that Germany was going to begin IQ testing on the ‘migrants’ to assess where talent and what occupational groups that they could put them in. This is a slightly positive change with all of the negativity this past year.
The mean IQ of Arab countries is 84 (Templer, 2010). With around 1.2 million ‘refugees’ coming from land and sea, assuming a SD of 15 (seeing as Arabs are Caucasian, I’ll assume a SD of 15), 50 percent of them fall at or below 84. So 600k at 84 or below. 16 percent fall at 100. 192k fall at 100. 12k at 120 and 1,680 fall at 130. 50 percent fall below 84. In America the average IQ for a repeat criminal is 85. With an IQ of 85, you can see that criminality begins to increase. This is due to lack of abstract thought(linked to verbal ability), which has them not think of the consequences of their actions before they act. At or below 85 is 1 in 6, 68% of the population is within 1 SD of 100, and 2.5% of people are 130 or more.
I can’t find any data on Arab testosterone at the moment, so I’ll just assume that it’s higher than Europeans due to the Arabs’ closer proximity to the equator (someone correct me if I’m wrong), as that’s why African’s testosterone is high. Due to higher average testosterone combined with low IQ, this leads to increased aggression along with increased sex crime, which is a cause for some of the sex assaults on European women by Muslim men. I can’t find anything on terrorist IQ, the closest I can find is how the FBI convinced a man with an IQ of 51 to attempt terrorist acts, though that’s an extreme case. Since low IQ is correlated highly with lack of abstract thought, it was easier for him to become convinced to do it. Like in most organizations, the more intelligent ones are at the top so they tell the lower IQ ones what to do. Though, by administering these tests, they will greatly lower their chances for another terrorist attack, seeing as those actions are correlated with low IQ.
In a study on prison inmates, IQ predicted inmate misconduct. Using a sample of 2500 inmates over 30 institutions from August 2004 to June 2006, it was found that those inmates who had higher IQs were involved in fewer incidents as well as being less likely to commit violent behavior. Verbal intelligence has been posited to be some of the cause for increased crime, seeing as verbal IQ is correlated with delinquent behavior, which is due to lack of abstract thought being correlated with lower IQ. With higher testosterone being correlated with low IQ and increased androgen sensitivity along with higher sperm counts (both are indicators of higher testosterone) being correlated negatively when measured by speed of neuronal transmission which causes a trade-off between g (general intelligence) and neuronal transmission, this shows that increased testosterone means decreased IQ. This is also seen with how higher IQ people have a lower sex drive.
I did say in my article Non-Western People are Abnormal for Our Society, that, as the title says, non-Western people are abnormal for our society due to not sharing our cultural values, which, we know is genetic. Though, higher IQ individuals will be better able to acclimate into society, as well as have a decreased proclivity to commit crime.
Since there are some evoultionary reasons for suicide bombings due to increased inbreeding this increased genetic similarity between them which led to increased altruism due to genetic similarity, by allowing those with higher IQs, this will lead to a greatly increased chance for attacks to happen as higher IQ people are better at controlling impulses.
This is a move I agree with. All countries should implement this procedure (obviously not enough to where it begins to displace the native population). With there being a cut-off limit on IQ, lets say 105 or even 110, that guarantees a high chance of those who are immigrating will be of value to the country and bring something to the table instead of the current situation with the benefits they currently receive (and lets be honest, you know these rules aren’t being followed). So by implementing this policy not only in Germany, but around the world, this would be a great thing for the West, to restrict immigration only to high-skilled workers, with a background check, intelligence test and someone with good credentials. Of course, only in sectors that really need the help. I of course advocate for the natives of any country to have first dibs when it comes to getting a job.
All in all, this is good move because a) rapes will be lessened and b) there won’t be as much individuals on welfare because there will be an (assumed) moratorium on those with lower IQs, leaving the higher IQ ones to find jobs and contribute to the economy.
Black Crime, Black Physical Attractiveness and Testosterone
I touched on black crime a bit a few months ago. I will now go more in depth on reasons for black crime.
First, what is the caused of all crime, no matter the race?
People have always said that parental socialization was the cause of black crime. But, genetic confounding was never considered in those studies. Kevin Beaver et al found in an analysis of adoptees that once genetic confounds were properly controlled, the effects of parenting on criminal justice measures were nonsignificant. That’s weird. I thought parental socialization was the cause of a kid turning out bad or good.
What is the cause of rape?
In a 37 year nationwide study in Sweden, it was found that sex offending runs in families. They reported strong evidence of familial clustering of sex offenses, mostly accounted for by genes and NOT shared environmental influences (ie, the same thing happening to both people in the family, therefore being the environmental cause of rape).
It’s of course genetics. We know that there is huge variation between individuals of the same race/ethnicity, how about between races? It also follows Rushton’s Rule of Three, Asians on top, whites intermediate and blacks on the bottom.
There are testosterone differences between blacks and whites. On top of those testosterone differences, men who stay and raise children have, on average, lower testosterone. This was noted in the West, but non-Western samples gave differing numbers. The study was conducted in two East African populations from Tanzania, Hadza foragers and Datoga pastoralists. They predicted that high levels of paternal care by the Hadza fathers would be associated with lower testosterone and that no difference would be found in non-fathers and fathers of Datoga men, who provide direct paternal care. The measurements in both populations confirmed the hypothesis, as well as adding further support that decreased testosterone leads to more paternal care.
What does that have to do with crime? Not having a father is detrimental to a young child, studies have shown in the UK that those from broken homes are more likely to commit crime than those from stable families. Also, seven out of ten offenders come from broken homes.
In this paper by Steven Ruggles, he says that analysis confirms that the high incidence of black Americans of single parenthood and children residing without their parents is not a recent phenomenon. Data shows that from 1880 through 1960, black children were two to three times more likely to reside without one or both children than white parents. This directly goes in the face of what liberals say is the cause of the demise of the black family structure. Ever since blacks have been free from slavery has this begun to happen.
Why did black father rates jump so much after the Civil Rights Movement?
I have my own theories.
Today, the black single mother rate is at 72 percent. In 1965, 24 percent of black infants were born without a father. What is the cause for that?
Blacks weren’t allowed to marry whites, and the CRA changed that. So with them being legally allowed to court white women, they obviously shied away from attempting to court black women. We can see that the trends show huge changes in 50 years. The cause is desegregation obviously, but what exactly is that environmental cause? Being able to court white women.
So with those men who DO stay around to raise children who show a decrease in testosterone, it’s extremely safe to say that those men who leave, regardless of race, have higher testosterone than those men who stay. This is reflected in racial single parent stats that show, again as for many more variables, Rushton’s Rule of Three.
What is wrong with black women? How come when segregation got lifted, black single motherhood rose exponentially?
Satoshi Kanazawa knows why. He noted in this study on why black women are not as attractive as other races, that women, on average are more physically attractive than men. EXCEPT BLACK WOMEN. The data shows black women as not being statistically different from the average, and far less attractive than whites, Asians and Native American women.
The cause is higher testosterone. Kanazawa says that the cause for this is due to the mean BMI of black women being 28.5 among black women and 26.1 among non-black women. Though he says that’s not the reason why black women are less physically attractive. Black women have lower levels of intellect net of BMI. Even the racial differences in intelligence don’t account for these differences. Black women are STILL less physically attractive, net of BMI and intelligence. Kanazawa says: “Net of intelligence, black men are significantly more physically attractive than nonblack men.”
Why is that? He says the reason is testosterone. He ends up concluding that testosterone differences are the only cause for these differences. With blacks having the highest testosterone out of all the races, black women obviously have higher rates of testosterone than white women. Those women with higher levels of testosterone have more masculine features, therefore making them less attractive.
Previous research has suggested that perceived attractiveness and personality are affected by the race such that White faces are more attractive but less masculine than Black faces. Such studies, however, have been based on very small stimulus sets. The current study investigated perceived attractiveness and personality for 600 Black, White and mixed-race faces. Many of the investigated personality traits were correlated with race when rated by White participants. Attractiveness specifically was greater for Black male faces than White male faces and among mixed-race faces. Blackness correlated with increased attractiveness. A reverse pattern was found for female faces with Whiteness being associated with attractiveness. The results are discussed in terms of the sexual dimorphism demonstrated in skin color. (Lewis 2010)
That’s the same as was noted in the Kanazawa paper. Darker-skinned males were more attractive, lighter-skinned women were more attractive.
Rushton wrote, in his last paper before his death, that skin color as a multi-generational adaptation to differences in climate over the past 70,000 years. He proposed life history theory (formerly known as r K selection theory) to explain the covariation found between human and non-human pigmentation and variables such as birth rate, infant mortality, longevity, the rate of HIV/AIDs and violent crime.
Dark skin is correlated with these things because of evolution.
High testosterone is linked to crimes of violence and sex. Men who gave saliva samples in prison were shown to violate more rules in prison, especially rules involving overt confrontation. Dabbs et al say: “the variety of rule violations suggests the behavior of high testosterone individuals reflects intractability, unmanageability, and lack of docility as well as aggression and violence.” Higher testosterone levels were associated with more violent crimes, parole board decisions against release, and more prison rule violations. This same thing was noticed in women, high-testosterone women had more crimes of unprovoked violence, increased number of prior charges, and decisions against parole.
For chronic adult offenders, the average IQ is 85, 1 SD below the mean of 100. Why do criminals have low IQ? Lack of abstract thought for one. Those with low IQ have a lack of ability to think of what their actions will do. Along with the lack of ability to delay gratification, paired with high testosterone and low IQ, that is the cause for higher than average crime in the black community in America.
Men with lower intelligence may be more likely to resort to evolutionarily familiar means of competition for resources and mating opportunities, and not to fully comprehend the consequences of their criminal behavior.
Even just a few points of IQ matter to criminality. There is a lot of data on the link between crime and low IQ. Who just so happens to have the lowest IQ in America on average?
It was noted in this study that states with lower IQs have more property crime and violent crime.
Increased intelligence is also linked to lower sex drive. I would reason that as shown above, those with higher IQs will be able to resist natural urges better than those with lower IQs. This shows in NLSY data with lower IQ people having more kids, higher IQ people fewer kids.
All of this data piles up, and the only thing that jumps out, is that lower IQ people have more testosterone, lower IQ people commit more crimes, therefore, high testosterone and low IQ is the cause of black criminality.
IQ, socioeconomic status, success in life and criminality
1700 words
Lower IQ people can’t work in the same jobs, or do the jobs they can get better than lower IQ people. This is a huge part of the reason why blacks talk about ‘oppression’ because they are too dumb to see that they are the reason for their downfall so they blame it on imaginary forces such as ‘white privilege’ or ‘white supremacy’. They don’t even know that 1) whites are the majority in this country and, therefore, have a majority of the jobs and 2) lower IQ people don’t succeed as much or do as better than higher IQ people.
To begin, IQ, along with height are 2 of the most heritable things for humans. IQ is malleable in children, seeing as the heritability of IQ is 22 percent at age 5, 40 percent at age 7, and 82 percent at age 18. So IQ is malleable in children when they are younger so you can change their IQ through the environment, but as they age to adulthood, to quote Jensen, their genes ‘turn on’ and fall to the average for that racial grouping. So in effect, the environment does nothing for IQ in adulthood as it did in childhood. Some people say that IQ is 100 percent environmental, and that is a really stupid position to hold as, through sub-tests and seeing the g loading in them, we can see that the most g loaded tests are highly heritable. People who say that IQ is 100 percent environmental are intellectually dishonest and are true ideologues.
Let’s talk about IQ in relation to job potential. Job performance can be measured in a lot of different ways. Sometimes through how many units per day per hour someone produces, or structured ratings by supervisors or peers or sometimes by analyses of a work sample. With that being said, the correlation between IQ and job performance is .4, with the correlation being higher on for more complex jobs. (pg 72) It is known that the higher someone’s IQ is, the better they perform at jobs and are better than people who have a lower IQ at that same job. They may be able to memorize more things, be more productive in the workplace or just have better motivation due to being more intelligent and knowing that his skills are being applied correctly in the workplace.
With the above being said, can you think of how that relates to blacks and how they cry oppression that whites hold them down because of ‘white supremacy’? It’s completely nonsensical and sounds completely baseless to anyone with a brain. Now that we know that IQ is highly heritable and is modestly correlated with job success, let’s see what it looks like in regards to getting a job and job applications.
According to The Bell Curve by Charles Murray and Richard Herrnstein, IQ tests are a better predictor of job success than compared to a job interview. They state that, while it may be surprising to many, IQ tests are a better predictor of job performance than any other single measure. This conclusion is drawn from a meta-analysis on the different predictors of job performance which are: (pg 80 and 81):

As you can see, the job interviews correlation is extremely low. That means that the relationship between the two are not highly correlated, meaning the relationship between them don’t have a good relationship. The cognitive test score (IQ test) is correlated at .53 with job performance. In social sciences, that is a pretty high correlation. A .6 correlation in social sciences is said to be a very high correlation. Think about how blacks act and then think about how they may act at a job interview. With that correlation, .14, being so low, it’s safe to say that they will not get a job based on that job interview. Even education has an extremely low correlation. Yes, your IQ is a great predictor of college success, but according to the table, which was found in a study of 23,000 civilian employees at 3 levels of mental ability (high, medium and low) using supervisor ratings as the measure of performance which also extended out to job tenures of 20 years or more, we see that the correlations that we believe are a good predictor of job success don’t have as high of correlations as we thought they did. We see that cognitive test scores are the best predictor of job success from that table, so with that being said, is it really ‘white supremacy’ or ‘white privilege’ being used to hold down blacks?
Now let’s get on to success in life. I pretty much covered that above, but let’s get more in-depth. According to Linda Gottfredson, the correlation for scores that are averaged has a correlation with job performance at .90. (pg 106) IQ is correlated with increased income, increased wealth, economic growth, livability in a US state, cooperation and life expectancy. IQ correlates negatively with socially undesirable outcomes such as crime, welfare dependence, and illegitimacy. Why people deny IQ having anything to do in life is crazy. All you need to do is look at your local down and out people and see how they act and how that comes to their ability to find and keep a job. You don’t even need to see these correlations and information to see this in real life, all you have to do is observe your surroundings and draw your own conclusions and if you are intellectual, you will see these things and draw the correct conclusions on the matter that don’t involve ‘white supremacy’ or ‘white privilege’.
Now let’s get to crime and how it is correlated with IQ. According to Arthur Jensen in The g FACTOR The Science of Mental Ability, IQ has a well-established correlation between a number of social variables such as poverty, crime, illegitimacy and chronic welfare status. He also states that verbal test scores are somewhat highly correlated with delinquent and criminal behavior than are nonverbal (spatial) suggests that other cognitive factors, in addition to g are most likely responsible for the correlation of IQ with the most common forms of antisocial behavior. (pg 294) Lower IQ is also known to be correlated with a lack of abstract thought and thinking into the future. Thinking of blacks, with an average IQ of 85 (Rushton and Jensen say that some data says 78) we can see how criminality is correlated with low IQ and how blacks have, on average the lowest IQ and commit the most crimes per capita in America. People may point to that data and say “Whites commit the most crime in America”, and while true, they don’t think of per capita rates as well as the population percentage in the country, which is 63 percent white and 13 percent black. That is what really matters.
The average IQ for a criminal is 84 in America right by the average IQ for blacks in America which is 85. That can not be a coincidence. We see how much crime they commit and how it has an effect on American life in regards to how the media portrays them as Saints in a crusade against ‘white supremacy’ and ‘white privilege’. We see that the problem in the black community isn’t whites “holding them down”, it’s due to their own biology, which they don’t have the average IQ to grasp that it’s them and not the people they blame for their downfalls.
A correlation is a mutual relationship between 2 things. So if the correlation was 1.00, then that would mean there is a relationship between the 2 things being tested. With that number, .92 being so close to the perfect correlation of 1.00, it’s safe to say, that the darker someone’s skin is, the less intelligent they are. You may point me to some outliers, but that is perfectly explained by the relationship not having a perfect correlation. If the correlation were perfect, then that would mean every dark-skinned person’s IQ would be low, but that’s not the case so you get some people who don’t fall into that category.
Rho is a population coefficient or the population Pearson correlation coefficient. It’s a measure of a linear correlation (dependence) between two variables, X and Y, giving a value of +1 and -1 inclusive where 1 is a total positive correlation, 0 is no correlation, and −1 is a total negative correlation. It is widely used in the sciences as a measure of the degree of linear dependence between two variables.
So we can see that the darker someone’s skin is, the more likely all of the above variables are to be seen in those with darker skin pigmentation. We can see that skin color DOES matter and anyone who says otherwise has no idea what they are talking about.
So the people harping on about how skin color doesn’t matter, it does and as you can see through this whole post, with IQ being THE best predictor of success in life, we can see how skin color matters as well.
In conclusion, what white SJWs and blacks say in regards to blacks being held down by the rich white men in America is clearly hogwash as I have shown to you in this thread. The black community will not succeed until segregation is put back into place. During segregation, they actually “succeeded” in their own lives because there was a clear separation of whites and blacks. Today, the single mother rate in the black community is 72 percent. 50 years ago it was 24 percent and in the 20s, it was 5 percent. The downfall of the black community is not white people.
