Race Realism: Modern Day Galileos
This will be the first in a long series of posts on who I think are Modern Day Galileos and their contribution to the study of racial differences/intelligence and all that good stuff. People who get shunned because their views aren’t ‘PC’.
Why do people deny race realism? Why do people deny that there are mental and behavioral differences between races, but acknowledge physical differences among races when science acknowledges it, but not when they mention IQ or other behavioral differences?
People deny it because people HATE hearing that they are wrong. Actually, telling someone facts on something when they are ignorant on the matter INCREASES misperceptions.
They’re scared. I find it funny that hundreds of years ago, even as recent as the early 1900s, that we knew that there are differences. What changed? Marxism. Communism. Some wacky belief that we are all the same even though races spend tens of thousands of years isolated from each other. These same people point to science when it goes against their beliefs, not when it goes against them. My brother told me that his CCD teacher said to him one day that there are Christians called “cafeteria Christians.” Meaning, that they read the Bible and cherry pick what they like and fits their views but omit the stuff that doesn’t or say it’s irrelevant. I’m pretty sure a lot of these people have differing levels of cognitive dissonance, because it’s so illogical to believe that we are all the same.
Where did this idea originate from? As far as my research indicates, the earliest was from Marxism. Anyone know if this is right or not? They need everyone to “be the same.” Racial differences don’t allow that to happen as we are all different and different groups of people, on average, some will be better than others, others not as good. People can say superiority and inferiority, but it’s just their buzz words they say so people cry racist and no further research gets done.
Let’s get to some of the leading people in this field. Let’s start with Rushton.
Rushton spent his life studying differences in races, intelligence and other factors. He got heckled as a racist and people gave character attacks in place of rebuttals to his claims. See some of this video. Start at 31 minutes to hear the end of Rushton’s part, then at 34, Suzuki gets up.
Skip to 31 minutes to get the part.
Suzuki didn’t refute not one of his points at until 3 minutes into his turn. Just ad hominems and character attacks. Sound familiar? Even well learned people still give illogical arguments to facts. Suzuki says IQ can be changed. It can be changed in children, because heritability is low but as you age, heritability increases. The way he puts his statement, makes it seem like you can make your IQ higher at any point in life. Wrong. Most people here know the reality of heritability of IQ. He says IQ doesn’t test intelligence. Why? What makes people give ad hominems in place of facts? They have been conditioned to accept these false truths from people who are scared to learn exactly how different we are.
When people do give rebuttals on why we differ in intelligence and other mental and behavioral traits, they are usually poor arguments that are easily refutable. Systemic racism, environment, which is influenced by IQ, as is culture, poverty and other easily refutable arguments. Silly arguments that quickly crumble when presented with facts.
Now Charles Murray and Richard Hernnstein, co-authors of The Bell Curve.
They also received much criticism on their book which the main topic is that human intelligence is influenced heavily by inherited and environmental factors and are indicators of success in life, income, job performance, crime involvement, out of wedlock births, parental socioeconomic status and education level.
Criticisms of the book are as follows.
Similarly, anthropologist C. Loring Brace in a review wrote that The Bell Curve made six basic assumptions at the beginning of the book. He argued that there are faults in every one of these assumptions
Human Cognitive ability is a single general entity, depictable as a single number.
It is called the g factor.
Cognitive ability has a heritability of between 40 and 80 percent and is therefore primarily genetically based.
Twin studies put heritability at .85.
IQ is essentially immutable, fixed over the course of a life span.
Yes. Only possible to raise in children as heritability is lower, as you age, heritability increases.
IQ tests measure how “smart” or “intelligent” people are and are capable of rank ordering people in a linear order.
Yes, they do measure this accurately.
IQ/g is the best single predictor, mental or non-mental. IQ/g usually predicts major life outcomes better than does any other single predictor in broad samples of individuals.
Results indicate an expert consensus that g is an important, non-trivial determinant (or, at least, predictor) of important real-world outcomes for which there is no substitute, and that tests of g are valid and generally free from racial bias.
“IQ is strongly related, probably more so than any other single measureable human trait, to many important educational, occupational, economic, and social outcomes … Whatever IQ tests measure, it is of great practical and social importance”
IQ tests are not biased with regard to race, ethnic group or socioeconomic status.
They aren’t biased. Whites and blacks get taught the same things. When they culturally load IQ tests with stuff blacks know, they score highly. For the people who say they are biased, we have Raven’s Progressive Matrices, tests based on picking the next matrice in the order. “Culture free IQ tests.”
Arthur Jensen is another great man in this field. Both him and Jensen have written great papers together. They refuted the Flynn Effect, which has stopped since the early 90s. His and Rushton’s twin studies prove IQ to be heritable at .85.
Jensen’s most controversial work, published in February 1969 in the Harvard Educational Review, was titled “How Much Can We Boost IQ and Scholastic Achievement?” It concluded, among other things, that Head Start programs designed to boost African-American IQ scores had failed, and that this was likely never to be remedied, largely because, in Jensen’s estimation, 80% of the variance in IQ in the population studied was the result of genetic factors and the remainder was due to environmental influences.
This is true. Headstart does really nothing for children.
Seems like Jensen has flipped from an environmentalist to the hereditarian position over the course of his career. Of course. Because as you attain new knowledge on a subject, you begin to reevaluate your views.
See some criticisms about Jensen.
What of the latest currents of thought? Are they likely to lead to, or at least encourage, further distortions of social policy? The indications are not all encouraging. Richard Herrnstein and Charles Murray published a book in 1994 clearly directed at policy, just as Jensen and others had in the 1960s and 1970s. The Bell Curve: Intelligence and Class Structure in American Life (New York: Free Press 1994) teamed a psychologist with a conservative policy advocate to try to prove that both the class structure and the racial divide in the United States result from genetically determined differences in intelligence and ability.
We know there are genetically determines differences in intelligence and ability. As I have said earlier, tens of thousands of years separated have resulted in mental as well as behavioral differences.
Their general assertions about genes and IQ were not very controversial, but their speculations on race were something else again.
How is that? Because they come to find that the truth, obviously, is not what people want to hear, because in the back of their minds, it makes them question what they’ve been taught their whole lives.
Jensen actually started off his career as an environmentalist, meaning he thought IQ was dictated fully by environment. He only looked in to the genetics of intelligence so he can say he looked at it and that there was no relationship between intelligence and genetics.
He wasn’t even mad at the people who attacked him for his research, he just wanted to them to look at the data. Someone who goes from an all environment outlook on IQ, to a mostly hereditary outlook on IQ, who actually follows where the data leads him, switched his position on the subject because the evidence was overwhelming. The point to bringing up Jensen’s past views on this subject are to show that even someone with a full on egalitarian mindset when it comes to this can and will switch their views when the data piles up enough, and look what came out of that. The most important psychologist of this generation, with the most cites and most papers.
This is the paper that reignited the firestorm on race/IQ and just IQ as a whole. A paper that never would have gotten written had he not looked where any and all data sent him. This is why all of our detractors should look at all of the evidence, then weigh it out themselves and not just listen to other non-experts on the subject, but actually, read it for themselves and attempt to digest all of the information and data so that they fully understand it. Even the most diehard egalitarian, if they are completely science-minded and not driven by emotions and politics will change their position.
You have people like Tim Wise putting all of this Marxist dribble into people’s heads. A class struggle, a race struggle. Those hierarchies are wrong and that everyone should be the same. Well, we know that in nature, hierarchies naturally exist. Why should humans be any different?
We all know that when people like us give facts like we give, they immediately cry racist as an attempt to stifle discourse. They think that ad hominem attacks end the conversation. We know that reality still exists whether these people want to admit it or not. They just look really ignorant denying facts.
People’s favorite ad hominem to use when we use our facts is to cry Stormfront. Like that changes the reality of facts. Because they know they can’t refute them so they do that and all of the other SJW jump in and berate the person’s accused character, all the while ignoring the facts. We all know who looks the most intelligent.
Let’s get to Guns, Germs, and Steel. For those of you who haven’t seen it, here’s the link.
Such a ridiculous argument.
So different levels of civilizations can be traced to environmental differences and not innate differences in races? Because physical environment can explain civilization differences does that mean all human brains are the same on average? Horrible strawman. Noone says environment doesn’t matter.
We can look at 2 countries within Sub-Saharan Africa. Look at South Africa. Still one of the wealthiest countries in Africa. Economic freedom isn’t the only source of wealth, human capital and natural resources are important. The lack of proper resources for civilizations in the past isn’t why Africa is poor today since we can see actual African countries that are better of by simply having more economic freedom.
The poverty today in Congo isn’t dated back to the dawn of time. Diamond says New Guineans are probably smarter then white Europeans. So does he accept that all races are the same in the brain except New Guineans? So does he then accept that human brains can differ in environments? Jared Diamond’s work is irrelevant and does nothing to explain why the various race performs differently in Europe. You can say racism or lingering effects of oppression, but the reasons for Africa’s poverty is not relevant to the racial gaps in Europe and America.
If you think it’s caused by environmental poverty in the past, you still have to argue the facts on racial differences today, the evidence still exists.
Jared Diamond is a man who spent a lot of time in Papua New Guinea. I guess he grew to like the natives there and befriended some of them so he makes ridiculous leaps in logic to actually say they may be more intelligent than Europeans. Hilarious. Any intelligent person can see the ridiculousness of what he claims. I can’t even begin to think how, when faced with all of this evidence of differences, that you can possibly believe in some warped view of equality or egalitarianism.
The same people who cry racist want to use racist policies to shoehorn minorities into places they don’t deserve to be in all in the favor of “equality and justice.” More intelligent whites and Asians lose out on a chance to get a good education all because they have to shoehorn minorities into places they don’t belong, because their, IQ simply doesn’t allow for it.
Rushton gives a great review of Diamond’s book here.
In Guns, Germs, and Steel, Jared Diamond joins the debate over racial differences in IQ. In a few ex cathedra pronouncements, Diamond brands the genetic argument “racist” (pp. 19-22), declares Herrnstein and Murray’s (1994) The Bell Curve “notorious” (p. 431), and states: “The objection to such racist explanations is not just that they are loathsome but also that they are wrong” (p. 19). He summarises his solution to one of philosophy and social science’s most enduring questions in one credal sentence: “History followed different courses for different peoples because of differences among people’s environments, not because of biological differences among peoples themselves” (p. 25).
The book grew out of an attempt to answer “Yali’s question.” Yali, a New Guinea native, allegedly asked Diamond, an evolutionary biologist, “Why is it that you white people developed so much cargo and brought it to New Guinea, but we black people had little cargo of our own?” “Cargo” refers to all that technology — airplanes, guns, steel axes — European whites brought to New Guinea, whose dark-skinned inhabitants were still using stone tools. Diamond’s answer, is that the peoples of the Eurasian continent were environmentally rather than biologically advantaged. They had the good fortune to have lived in centrally located homelands that were oriented along an east-west axis, thereby allowing ready diffusion of their abundant supply of domesticable animals, plants, and of cultural innovations.
As a card-carrying “race-realist” (Rushton, 1995), I should register my objection to Diamond’s claim that Guns, Germs, and Steel is a good faith effort to solve one of the most controversial and enduring controversies in the history of philosophy and social science. However well written, however encyclopedic in scope, and however much truth there may be in this book about 10,000 years of human history, Diamond does not give his readers the whole truth and nothing but the truth. In fact, he gives them much less. Inexcusably for an evolutionary biologist, Diamond fails to inform his readers that it is different environments that cause, via natural selection, biological differences among populations. All of the Eurasian developments he described created positive feedback loops selecting for increased intelligence and various personality traits (e.g., altruism, rule-following, etc.).
In recent years, the equalitarian dogma has been hit hard by some bad karma. In the wake of the success of The Bell Curve and other recent books about race (including my own) to provide race-realist answers to the question of differential group achievement, there has been an intense effort to get the ‘race genie’ back in the bottle, to get the previously tabooed toothpaste back in the tube. It is in such times that Diamond provides an answer that, just coincidentally, shores up the walls of the politically correct fortress, when they are being threateningly undermined by scientific research.
Rushton, as usual, gives a great review and discredits most, if not all of Diamond’s thesis in the book.
If these trends continue, we can expect to see a huge shift in the climate of America. Because the people who have the intellect and grades to get into good colleges get passed up for minorities. I don’t even need to explain how this will degrade society by putting people in a place where they don’t belong.
We all know of the SAT scores and how they correlate at .81 with intelligence. We all know how blacks consistently score lower than whites, even blacks from high socioeconomic status homes and whites from a poor socioeconomic situation. The leap in logic to say that forces are actively holding down blacks is ridiculous. The IQ gap has held consistent and there are 100 years of studies to back this up. We know it is mostly heritable.
America will go through a paradigm shift soon. A country doesn’t stay the same for too long. It was only 100 years ago that people understood the realities of race. We are due for a paradigm shift in consciousness soon. I can feel it. To actively deny things, especially when presented with well-sourced facts, is very ignorant. These same people who claim to be so intellectual show how unintellectual they are when they don’t look at evidence that differs from their own beliefs or even attempt to refute facts.
These 4 men, among many others, will be recognized as modern-day Galileos. No country can scoff at facts and reality for so long before it finally becomes accepted. It’s simply illogical to ignore facts for so long. As we all know, just because you ignore something, doesn’t make it not real.
In conclusion, the denial of race realism is simply illogical and a stupid belief based on ignorance to facts and inability to be able to refute the facts because their mind won’t let them because of their set beliefs. I used to be like that. I used to think everyone was the same, that we are all equal. Then reality hit me. Like it will hit everyone in the country soon. As black Americans continue to riot for people, when they get killed by police when police have a right to protect their lives when they feel threatened, more Americans will wake up to the fact that we are all different and that multiculturalism doesn’t work. Black people have basically been babied for the past 50 years with trillions of dollars spent to try to make them equals, yet they all failed. All waste money. Just think, if we were to recognize these differences how much greater of a society America would be. A paradigm shift is coming, and it’s coming soon.
These and many more reasons are why these men, along with others, will be known as modern day Galileos.

Refuting Afrocentrism Part 1: Olmecs Were Africans?
All over the Internet, you may have seen ‘Beethoven is black’, with an accompanying picture. Or that Mozart was black, or Hannibal from Carthage or other historic figures from antiquity were African Negroids. We all know it’s not true. Afrocentrists just take things that agree with their viewpoint, and warp anything they can in an attempt to say that “they were African”. There are tons of these lies going around the internet, with enough people who believe in Afrocentrism religiously, convinced that the white man hid knowledge of past African greatness. This will be a series of posts on Refuting Afrocentrism, with each successive piece focusing on a different part of the Afrocentric narrative.
I’ve had an interest in Mesoamerican history since I was a kid. I was reading adult level books when I was 10 years old. I got this book, The Mayan Prophecies: Unlocking the Secrets of a Lost Civilization, which talked a lot about Maya history, as well as where they came from. It’s an extremely interesting book, which goes through the history of the Maya, their astrology, mathematics, agriculture, building methods and so on. It said nothing about the Maya being African. That’s because it’s just Afrocentric rubbish.
Recent new evidence has said that the Olmecs and the Maya were easy to differentiate in the Classic Period (250 to 900 AD, which was their Golden Age) because they had language and culture distinct from the Olmecs. It’s said that while the Olmecs were building La Venta in Mexico, the Maya were living in loosely associated nomadic groups to the east and southeast. That holds that the Maya developed from the Olmec, but Ceibal is 2 centuries older than La Venta. Though, the researcher says that there was a flow of ideas and culture between the two locations and that through those interactions, a new society developed. He says from 1000 to 700 BC that that La Venta and Ceibal were freely trading ideas, technology, culture, and maybe even people.
From this study on Maya genetics, you can see that it says the closest group to the Maya were the Arhuacs, the first recorded Caribbean inhabitants. They are not genetically close to the Mesoamerican Zapotec, Mixe and Mixtec, who generally cluster together. The Mixe are only related to the Maya on a linguistic basis. DRB1*0407 and DRB1*0802 alleles are found in 50% of Mayans, they’re also found in other Amerindians, but the Maya’s high frequencies may be because of a founder effect from the Mesoamerican-Caribbean population. They described Maya-specific HLA haplotypes (which are involved in inflammation as well as other immune system activities). Some HLA genes have many possible variations, allowing each person’s immune system different protections against certain diseases. Language and genes do not completely correlate in microgeographical studies.
“Significant genetic input from outside is not noticed in Meso and South American Amerindians according to the genetic analyses; while all world populations (including Africans, Europeans, Asians, Australians, Polynesians, North American Na-Dene Indians and Eskimos) are genetically related. Meso and South American Amerindians tend to remain isolated in the neighbour joining analyses.”
This further proves another point that I read. That Mesoamericans are the furthest genetically from Africans, because of no genetic mixing between any populations with Mesoamericans, allowing their DNA to go from distinct East Asian (because Native Americans are descended from Siberians who crossed the Bering Land Bridge 12,000 years ago, since they evolved completely separated from Africa, no gene flow from anywhere else in the world got to the Mesoamericans, and over thousands of years they developed to be a genetically distinct group), to their own distinct genetic clade.
This is attributed to isolation from the rest of the world, as well as faster evolution. That is another reason why I believe the once great Mesoamericans are how they are today, because 1) because the Spanish killed off all of the high-status people, who were more intelligent, as well as disease killing them off. The slave population they had would have been more immune to the diseases. 2) Faster evolution. With evolution in a hot climate for tens of thousands of years, in comparison to where they first evolved when they were still genetically similar to East Asians, it obviously changed their genetics to make them distinct from East Asians, but not enough to get rid of the intellect they had already due to the Ice Age evolution. Anyway, I’m digressing, that will be for a future post.
Now to see Olmec genetics (Mexican Mazatecan Indians), who are pretty similar to the Maya, as noted above.
Findings were indirect evidence of Olmec/Maya relatedness, further supporting the theory that the Olmecs were the precursor to the Maya. Again, language and genetics do not correlate in the microgeographic area, a significant genetic output is not noticed at all in Mesoamerican populations while all other world populations (Africans, Europeans, Asians, Australians, Polynesians, North American Na-Dene Indians and Eskimos) are genetically related. As I said above, Mesoamericans are so genetically distinct due to faster evolution as well as no gene mixing between regions, which, over time, caused their DNA to mutate to the clade they have today. Both Central and South American Indians are genetically distinct from the rest of the world.
So we can see that all Mesoamerican populations are mostly similar to each other, except the Maya who are pretty unique, most likely due to the founder effect from the Caribbean.
The name ‘Olmec’ is a Nahuatl word meaning ‘the Rubber People’ Nahuatl is an Aztec language. They extracted latex from rubber trees. The Olmecs were thought to have died out around 400 BC.
Now that we have a good background on the Olmec and Maya connection, as well as Maya and Olmec genetics, let’s see what this Afrocentric Olmec theory is about.
The theory of Olmecs being Africans was first developed by Ivan van Sertima in the 70s. He wrote a book called They Came Before Columbus: The African Presence in Ancient America (Journal of African Civilizations). He first developed the theory from seeing the giant stone heads the Olmecs made, which look distinctly Negroid in appearance, as seen in the picture below.
Sure, from direct outward appearance, I can see how people would believe how the head looks like that of a negroid, but genetics tells us a different story.
Van Sertima claims that Mali seafarers reached Mesoamerica, and had consistent contact with the Olmecs, trading ideas and culture with them.
As I said above, most Mesoamerican populations are related to each other, with having no admixture from other parts of the world that all other populations have. So, if the Malinese people did have contact with them, we would find some of their DNA in Mesoamerican peoples today. We obviously know how ‘Hispanics’ came to be today, Spaniards mixing with the ‘Natives’. So, if we have Spaniards mating with ‘Natives’, and Mali supposedly had contact with Mesoamerica, then logic would dictate that genetic testing would find African blood in Mesoamerican populations.
But, as I noted earlier in this article, Mesoamericans are genetically distinct from all populations. We can see here that neighbor-joining analyses were done by putting together many worldwide and American populations. Both analyses show that Meso and South Amerindians are not related to the Na-Dene, because they came in one of the 3 migrations out of Siberia into the Americas. They are also not related to the Eskimos. Mesoamericans also do not show any relatedness with Polynesians, Australoids (discarding a massive Pacific colonization), Caucasians or African blacks. Genetic evidence also suggests that people moved from South America to North America into Siberia.
So why are there clear negroid features on the Olmec heads? Because they were obviously modeled after the Olmecs themselves. We know that the shapes of people’s noses comes from the climate that their ancestors evolved in. It has to do with temperature and moisture in the air. In areas where it’s extremely dry and has a lot of heat, a larger mucous area is required to moisten inspired (breathe in; inhale) air, which is why a more flat and narrow nose is needed. Olmecs and West African-descended peoples have short, flat noses because they lived in wet and tropical areas, whereas Nubians and Egyptians have longer and thinner noses due to living in the desert.
Here are some peoples who are said to be descended from Olmecs. There are pictures of statues as well as modern day people who look like them.
The Olmec statue heads are clearly of the indigenous peoples in the area, and not of West African Negroids.
Because of that one man’s theory, you have all of these Afrocentrists, with absolutely no understanding of genetics or human migration, who write these articles saying that any and all peoples and old/ancient cultures were negroid based on shoddy evidence and only physical appearance as well as cockamamie theories.
I’m pretty sure I have given way more evidence than is needed that the Olemcs were NOT negroids, but alas, you still have people who parrot this clearly refuted and untrue things, because they have absolutely no grasp on humanity in antiquity and will take any type of ‘theory’ that fits their warped worldview.
My brother told me a few years ago “If you’re looking for something, you’re going to find it”. Well, this is a perfect example of that.
In conclusion, because of genetic testing, as well as evolutionary factors which explain the ‘negroid-looking statues’, as well as most Mesoamerican populations being similar with each other completely debunk any and all notions of the Olmecs, and all Mesoamericans for that matter, to be African negroids.
Higher IQ Means Longer Life
I’ve been reading a few articles recently on how intelligence is correlated very highly with life expectancy. Researchers have found that the link between life expectancy and IQ is 95 percent. That makes a lot of sense. Those with higher IQ’s are able to think further into the future and predict outcomes based on previous events that took place, which manifests itself with a longer life expectancy. It also shows the reverse, those with lower IQ’s live shorter lives, which is because of not thinking of future actions due to a lack of abstract thought due to lower IQ, as well as all things that come with a low IQ, such as disease treatment, nutrition, etc.
Many studies have taken a look at this relationship, and each time, the correlation is a positive correlation. Which obviously signifies that IQ (even if we don’t exactly know what IQ tests test), that a higher IQ obviously leads to more favorable outcomes than if that same person were to have a lower IQ.
Looking at some high IQ countries and their life expectancies, we see that the relationship between IQ and life expectancy is very large and worth taking note of.
Taking the top 5 countries in IQ, we have Hong Kong (IQ 108, average life expectancy 83.48 years), Singapore (IQ 108, average life expectancy 82.14 years [though Singapore has a Chinese super majority of 76 percent]), South Korea (IQ 106, average life expectancy 81.37 years), Japan (IQ 105, average life expectancy 83.10 years), Taiwan (IQ 104, average life expectancy 79.84 years), and Italy (IQ 102, average life expectancy 82.94 years).
Now, from the same link in the previous paragraph (ignoring Equatorial Guinea’s numbers, since that was the average IQ of developmentally disabled children in Spain), Saint Lucia (IQ 62, average life expectancy 74 [anomaly here, HUGE anomaly, from some quick searching, I see that a majority of their hospitals are US-owned.]), Mozambique (IQ 64, average life expectancy 49.84 years), Gabon (IQ 64, average life expectancy 52), Cameroon (IQ 64, average life expectancy 54.59 years), and The Gambia (IQ 66, average life expectancy 58.61 years).
Now, the only anomaly was St. Lucia, which is explained by US-owned hospitals. So we can see, from the top as well as bottom 5 countries in IQ, that the trend holds true for the top 5 intelligent, as well as bottom 5.
We know how lower IQ came to be in peoples in the equator, so I won’t even go there.
Of course, with lower average IQ’s, come increased aggression, lack of thought into the future, as well as a myriad of other things negatively correlated with a long life span. That, obviously, like most things in life, is due to evolution and genetics. We see the same impulsivities where ever low IQ peoples go, in whichever countries they choose to live in, proving that it’s not ‘Magic Dirt‘, but genetics and intelligence which dictate life expectancy.
For a lot of those countries (most undeveloped countries I would say), they are nutritionally deprived. Having better nutrition obviously increases IQ (a lack of B vitamins, iron, zinc and protein deficiencies is partly the cause for lower IQ in regions where nutrition is horrible is part of the reason why there is lower IQ in these regions), but obviously, they don’t have the intellect to know, or even learn how to farm to make their standing better. That’s the rut that these peoples in these countries are in. They are too stupid to learn how to farm, and they can’t learn how to farm because their IQ is depressed due to bad nutrition, which is due in part to their low IQ etc. It comes down to a which causes which, and I say that the climate causes the low IQ, which leads to them not being able to adequately feed themselves to give their brains proper nourishment and development.
For instance, Richard Lynn says that with better nutrition that Africans could go from average 70 IQ to 80 (he says 67 to 80, so a 13 point boost). He also says that blacks in America with no white admixture still have an IQ of 80, so that proves that nutrition is part of the cause of lower IQ in African blacks. He claims the ‘Flynn Effect’ to be driven mainly by nutrition, which I am inclined to agree with him there as I love studying nutrition, and other than race differences, IQ and HBD, I also study that on my free time.
We have many examples, from Rhodesia/Zimbabwe, where the white farmers were kicked out. The more intelligent black farmers knew that without whites there, they wouldn’t be able to survive. So they tried to get the white farmers to teach them how to farm, but Mugabe found out and stopped it.
But now they want the farmers to come back. They know that they can’t survive just on their own, so they are now begging for what they had before they drove out the farmers who gave them their food.
Now for a fun thought experiment. What do you think the average life expectancy of Africa could be with that IQ 80? Let’s look at average life expectancies of countries with that IQ.
Barbados life expectancy, 75.13 years, IQ 80. El Salvador, life expectancy 72.10 years, IQ 80. Sri Lanka life expectancy 74.07 years, IQ 79. It’s clear that those with IQ’s in the 80’s have an average life expectancy of low to mid 70’s.
In this article, which is just an attack on racialist IQ researcher Satoshi Kanazawa, it’s of course just said that “‘ridiculous’ for Kanazawa to blame ill health on low IQ and ‘very irresponsible’ to reach such conclusions using questionable and ‘fragile’ international data on national IQ levels.'”
Kanazawa declined to comment on either War on Want or Atkinson’s allegations about reviving eugenics because, he said, other academics had come up with the national IQ scores that underpinned his analysis of 126 countries. In the paper he cites Ethiopia’s national IQ of 63, the world’s lowest, and the fact that men and women are only expected to live until their mid-40s as an example of his finding that intelligence is the main determinant of someone’s health.
He’s 100 percent right. I love how no rebuttal was put out, and feelings were used in place of a good, solid retort to the facts.
Fragile? Yes, scores that can be duplicated time and time again, and even when retesting of IQ tests have a correlation of .87, it’s still ‘fragile’. Got it.
The Chairman of the Kenyan Society (totally unbiased opinion there) said ‘lack of education was probably one reason why many Kenyans die young. Aids, tuberculosis and malaria were key factors too.’ Yes, lack of education. How educable you are is down to how intelligent you are, not the other way around.
The same person also stated ‘[Kanazawa’s paper is a] misrepresentation of the true causes of ill health in Kenya. It portrays a bad picture of Kenya because not everyone in Kenya has an IQ of 72. If there was more education, Kenyans would be wiser about their health.’
Yes, not everyone in Kenya has an IQ of 72, half fall below it. =^) Again, what do you think you can teach to a person with an IQ of 70? How about in comparison to a person with an IQ of 110?
So, we can see with that boost to African IQ, their life expectancy will increase along with their IQ, further proving the positive correlation between IQ and life expectancy.
The Marshmallow Experiment
This is one of my favorite studies. It proves a genetic basis for the ability to delay gratification, as well as racial differences in the ability to delay gratification.
In the late 60s and early 70s is when these experiments took place. Walter Mischel who is now a psychologist at Columbia University, thought of a groundbreaking study to see the ability to delay gratification. Taking preschoolers, the researchers presented the child with treats such as marshmallows. The child was then told the researchers had to step out of the room for a few minutes. Before they left, they were told that if they didn’t eat any of the treats, they would get an extra treat. If they couldn’t wait, they were told to ring a bell and the researcher came back and they were only allowed one treat.
There were interesting ways in which some of the children who were able to prevent themselves from eating it. Some of them pushed it further away from them, turning around in their chair and singing songs to themselves to distract themselves.
He eventually developed a framework to explain the ability to delay gratification called a hot and cold system, to see explain why willpower fails.
The cool system is the thinking system, the cognitive one. Reminding you that you will get a reward if you wait. The hot system is the impulsive system, making you want it now and not wanting to wait for the other treat.
Years later, another researcher was able to track down 59 of the participants in the study. They then tested them again, and their self-control was the same.
Some important things were found from the studies. It predicts BMI 30 years later in preschoolers, they predict SAT scores, educational achievement, as well as significant correlations being found between seconds of delay time and cognitive and academic confidence and ability to cope with stress and frustration in adolescence.
MRI scans were also given to them where they were presented with tempting stimuli, those with low self-control showed differing brain patterns in comparison to those with higher self-control. The prefrontal cortex, the part of the brain that makes choices, was more active in subjects with higher self-control. The ventrial seratum, which is thought to process desires and rewards, was more active in those with low self-control.
We see in this study that brain structures are involved in the ability to delay gratification, as well as psychopathic disorders. The hippocampus, which is associated with memory, and the nucleus accumbens, associated with pleasure, work together in making critical decisions of this type, in which time plays a role. Blacks have a smaller hippocampus, as well as nucleus accumbens due to having a smaller overall brain in comparison to whites and Asians.
In one study done in the 60s on East Indians and Negroes on the island of Trinidad, a major personality difference was expressed between the 2 groups. Many people said that the difference was that negroes are impulsive and would settle for next to nothing if they could get it right away, as well as not working or preferring to work and they preferred to accept smaller things immediately. But the Indians were able to deprive themselves and able to postpone immediate gain for a bigger gain in the future. The black took the smaller reward if they could get it right away whereas the Indian waited if they could get a bigger reward in the future.
They also say at the end of the paper that this has implications not only for the 2 ethnicities in the study but for further research for studies on relationships between personality variables and this type of behavior in our own culture.
They have also done this test on blacks and whites in the Caribbean as well as the US multiple times and are sick of doing it because the results are always the same.
Now that we have a background on the delay of gratification as well as some a study that shows how blacks fare in it, let’s see some real world examples.
We all know that blacks rape the most. They kill the most. They rob the most. They assault the most. All of that has to do with thinking in the now, ability to delay gratification. The gratification of them of raping, killing, robbing or assault. Because they have a smaller brain than we do, they’re not as developed in the areas of the brain that we are (which has to do with archaic hominid admixture in Africans). That leads to them only thinking in the now and not thinking about the future. That’s one of the causes for black over representation in murder and all other crime stats despite being 13 percent of the US population. They don’t think before they act, right when it pops into their head they act on it. With their low IQ on top of that, along with the smaller, less developed brain, leads to all of the impulsive behaviors that show itself in the crime stats on all the countries where blacks are the majority.
Ability to delay gratification is clearly largely genetic. I would reason that since Africans evolved in a hot climate where food is readily available, they didn’t need to do the planning ahead that Europeans and East Asians had to do. With the groups who weathered the Ice Age, they had to conserve their food and save it. This lead to an evolutionary effect over time, ability to delay gratification, along with high IQ and more altruistic behavior towards the group.
It’s the opposite in Africans and those who evolved in hotter climates closer to the equator. There was really no need to delay gratification for things such as food and other things of that nature because they didn’t evolve in the Ice Age.
This same trend holds true for all peoples who evolved close to the equator. So ability to delay gratification is correlated with ancestry, as well as skin color.
Another cool thing I just came across the other day is Western Europe, state formation, and genetic pacification. It says that pacification proceeded slowly from the 5th to 11th centuries, because of the Church’s opposition to the death penalty as well as belief in a man’s right to solve personal disputes as he saw fit. They began to dissolve in the 11th century with a consensus that the wicked should die so that the good may live in peace. Courts imposed the death penalty more often in the middle of the Middle Ages and by then they were putting to death .5 to 1 percent of men that generation, with the same amount dying at the scene of the crime or getting killed in prison awaiting trial.
The homicide rate plummeted from the 14th to 20th centuries. By then, most murdered were committed due to jealousy, intoxication or extreme stress. The decline in violence is attributed to more strict punishment as well as long term effects of cultural conditioning. Though, the new cultural environment may have selected against propensities for violence.
That is clearly the people with lack of ability to delay gratification being culled from society, which proved it with its murder drop in the 14th to 20th centuries.
In Sweden, those with a certain MAOA allele are said to commit between 5 and 10 percent of crime.
Sexual offending run in families.
Those are clear things that show a lack of ability to delay gratification, and as I have shown here it is genetic.
Those that live in/evolved in hotter climates have a higher propensity to commit crimes and other negative things to due certain pressures that they didn’t have to go through, leading to the long list of things that all strongly correlate with each other due to the reason (evolution and hot climate) why we are all different from each other.
Ethnicity and Obesity Rates
Figured I would take some time to talk about some Racial-Ethnic Disparities in obesity, and for as of right now (while the populations still show differentiation, it will be way different for all ethnic groups in 20 years with 9 out of 10 people being obese or overweight, and I would assume it would show the same levels of it in all populations), the ethnic-racial differences in the pattern as they apply to HBD.
To quote from the Food, Research and Action Clinic, which just did an overview of studies from the last year on the percentage, as well as racial-ethnic disparities on obesity:
Recent national data show that 82.0 percent of Black women and 77.2 percent of Hispanic women are overweight or obese compared to 63.2 percent of White women (Ogden et al., 2014).
Women as a whole are more likely to carry more fat mass than men, especially in their hips and around their waste, as estrogen distributes fat more around hips and the lower body, as it’s better for childbearing.
In addition, over half of Black women are obese (versus 37.1 percent of Black men and 32.8 percent of White women) (Ogden et al., 2014). Extreme obesity continues to be higher among women (8.3 percent) than men (4.4 percent), especially among Black women who have more than double the rates of extreme obesity as White and Hispanic women (16.4 percent versus 7.4 percent and 7.6 percent) (Ogden et al., 2014).
Black women have a higher rate of super obesity (over 40 percent BMI) due to EBT and other programs where they are able to buy high fat, high carb foods, which obviously leads to more weight gain. Double the fact that they are women and genetically predisposed to carry more fat than men, and you have your answer.
There is also a genetic component, which I will get in to later.
Rates of overweight or obesity are higher for Hispanic men (78.6 percent) compared to Black men (69.2 percent) and White men (71.4 percent) (Ogden et al., 2014).
Definite genetics at play here, with Hispanic men having a higher rate than black or Hispanic men. Studies show that Hispanics have fat-hoarding genes left over from their ancestors, genes that were required to live through cycles of feast and famine, which obviously have deleterious effects today. (Type 2 Diabetes goes hand in hand with obesity, which I will cover in a future post.)
This also goes to people who say that there are no genetic causalities for obesity, sure kcal in and kcal out are king, but it’s ignorant to think that there are no genetic causes for obesity.
There is a gene that is associated with waist circumference, as well as insulin resistance. Asian Americans have that, which also is a cause for obesity. Also, that same MCR4 sequence has been linked to binge eating.
Now to talk about some genes associated with obesity in African Americans.
In a study published back in 2013, researchers were looking for obesity genes in African Americans. The study, which involved more than 70,000 men and women of African descent, they were able to identify 3 SNPs that were associated with obesity and BMI in the sample population. What was also found, was that those same genetic sequences also heighten rates of obesity in peoples with no African ancestry, all of the genetic variants associated with obesity were also found in European populations. The same genes found in African populations did the same in European populations, and vice versa.
The map shown above shows obesity rates among black adults. Of course, where blacks are most prevalent, the southeast shows higher concentrations of obesity, of course, environmental factors are at play here (with ‘soul food’ being super high in fat and carbs, which make you hungry sooner).
This map shows the obesity rate of whites in America. Notice how most of the concentration of obese whites is in the southeast of America, which correlates with the lower IQ average of those states as seen in the map of IQ by State.
The above map shows obesity rates for Hispanics in America, again, matching up to where the majority of Hispanics in America are, furthering the causality of low IQ (see map).
Notice how there is no Asian obesity map? That’s because of their higher average IQ. Asian countries have some of the lowest prevalence of obesity and being overweight worldwide. Though, that is changing with a more ‘Americanized’ Asia, us bringing our shit lifestyle habits to other countries will increase the overall prevalence of obesity in the world, as well as America.
You can see the average IQ scores by State that it roughly matches up with all 3 maps. It’s not a coincidence. Lower IQ people don’t grasp what they are doing to their bodies by eating so much, leading to higher rates of obesity. I have already touched on how high fat diets slow microglia, which eats neuron connections in the brain, which is, yet again, another cause for lower IQ in obese/overweight people.
On top of some genetic reasons for obesity and predisposing populations to obesity, there are also environmental effects which cause differing levels in the populations. Socioeconomic status has a say as well (which is one of the only times this is applicable).
With differing levels of government assistance in groups, the more people who get government assistance are, for the most part, on the left side of the Bell Curve, which in turn means that they have a higher chance of being obese or overweight, due to low intellect. Low intelligence is correlated with abstract thought, so the low IQ person won’t be able to see what they are doing to their bodies in the now as well as into the future. That is the relationship between IQ and obesity.
Kanazawa also found, looking at a nationally representative sample of white Britons, (n=10,000), that IQ measured in childhood predicts obesity by age 51. (I will make a longer post on IQ and obesity in the future.)
Also, in a study that came out last month, when diets make us overweight/obese, it prompts normally active cells in our brain called ‘microglia’ to stop moving around so much and actually consume pathways to our neurons, which of course can sap intellect.
Percent of population on Food Stamps by Race:
As you can see here, blacks have the highest rate of receiving food stamps in the country. The above quote is taken from the link.
It doesn’t follow the obesity trends of 67.3% for whites, 75.6% for blacks, and 77.9% for Hispanics, genetic factors take care of the rest for Hispanics to show their numbers in the obesity statistics. Obviously, we are being bombarded with tons of ads a day, telling us to eat all of this unhealthy food, and who is more likely to be home and not at work? Blacks and Hispanics. So that propaganda from the TV effects them more, to eat this or drink that, and they give in, due to their low IQ (which I have linked 2 Kanazawa studies to show reasons why).
In a meta-analysis of 140,525 people, they found the heritability of BMI was .75 to .82. So we can see that heritability of BMI is pretty large.
The causes for race/ethnic differences in obesity are partly genetic and partly environmental (socioeconomic), one would reason, in equal environments, that we would see Hispanics take the top spot, with blacks following behind and finally whites.
The greater your IQ, the lower your weight. Researchers found that people with a BMI of 20 or less were able to recall 56 percent of words in a vocabulary test while those with a BMI over 30 could only recall 44 percent. This directly goes hand in hand with my other link about microglia.
In this study, the cohort members who became obese had low IQ, as expected. Obese cohort members showed no excess decline in IQ, they instead had lower IQ since childhood. Further proving the low IQ/obesity correlation.
By 2020, 75 percent of Americans will be obese or overweight and by 2020, 80 percent of men are going to be overweight or obese. Now, the cause of these trends going up are due to more illegal/legal immigration from the south of the border. Though, without that, we would still be on our way to being a super obese country, because of the dysgenic effects in all populations, which cause a drop in IQ, which causes a gain in weight. Not to mention the propaganda that gets put to kids to want to eat sugary, unhealthy things.
IQ, Inbreeding and Clannishness
The effects of inbreeding have an effect on IQ, as well as the amount of clannishness that leads to more inter-group violence.
According to one of my favorite researchers, Linda Gottfredson, in this article she wrote for the New Scientist:
Not only that, as more people travelled and married outside their local group, populations may have benefited genetically from hybrid vigour.
Inbreeding is known to lower intelligence, and outbreeding can raise it.
“Marrying outside their local population” means not marrying the immediate people in their local group, not other races.
So inbreeding (up to first and second cousins) is the cause of lower IQ. According to Razib Khan, inbreeding can lower IQ by 2.5 to 10 points. Outbreeding meaning breeding with others with less similar genes (not race-mixing). Talking about inbreeding and lowered IQ, we have to talk about Islam.
In a paper on the mean IQ of Muslims and non-Muslim countries, Donald Templer states that the Muslim world, which used to have great intellectual achievements from the 7th to 12th centuries, has seen an underrepresentation in highly creative contributions in science journals. This is because of the inbreeding effect (2.5 to 10 point drop in IQ) of close cousin marriage. He ends up saying that genetic factors are more important than social/cultural/religious values (back to the inbreeding, causing defects and lowering IQ) in regards to IQ.
In this great article by hbd chick, her definition for clannishness is:
“a set of behaviors and innate behavioral traits and predispositions which, when found in a population, result in the members of that population strongly favoring, in all areas of life, themselves, their family members — both near and extended, and even closely allied associates (esp. in clannish societies which are not arranged into clans), while at the same time strongly disfavoring those considered to be non-family and all unrelated, non-allied associates.”
Which you can obviously see in populations that are more inbred than others.
Those innate behaviors which result in the favoring in all areas of life, themselves and their family, is a result of genetic similarity because of the closely related genes they share (the father’s brother’s daughter type is the most common in the Muslim world). Also, first and second cousin marriages are more common, which also result in increased altruism for their own family because of the close genetic similarity, but also those in their own group, which is mediated by the brain hormone oxytocin. I would assume that all of these clannish/inbred groups would have higher levels of oxytocin in the brain. The same chemical is also known as the ‘love chemical’, which would make sense with ‘love for your own group or family’.
That same drop in IQ also made them more susceptible to the dominant religion (Islam) in the region. Causing more fanaticism (which is already there from the low IQ, as well as the between group strife with other ‘clans’), this also leads to more strife between groups in the region.
In the map seen above, you see the consanguinity rates for the world. The rates with the highest amount in the world, are in the Middle East and North Africa, as well as South East Asia, the majority Muslim parts of the world, which leads to depressed IQ, group violence, and violence against others not like themselves (as mediated through oxytocin).
That same clannishness is being brought to Europe, and with more increased cousin/brother/sister marriages, clannishness/genetic defects will increase, causing more strain (as well as violence due to that clannishness) that is already currently put on them through the ‘migration’.
Whites in Europe, as well as America, need that same clannishness. But obviously breeding too closely with those related to you (having genes that are too similar, which lead to a multitude of effects of inbreeding depression, lower IQ included) leads to a slew of negative effects.
Let’s see this article where a Muslim says “Why Ban Cousin Marriage?”.
The risk of birth defects in children born to first cousins is increased from a baseline of 3-4 percent to 4-7 percent according to the National Society of Genetic Councilors (NSGC). In this modern age, this risk could be mitigated by mandating — as the State of Maine has done — pre-marital genetic testing. The NSGC, however, considers the risk to be so insignificant that it does not recommend additional testing or screening.
31 percent of all anomalies in Pakistani children could be contributed to consanguinity. Really solid case of trying to keep first-cousin marriage alive. Also, just see how IQ drops when first-cousin marriage is done as well as the birth defects.
As you cross the scientific hurdles, you will be confronted with a mountain of taboo cloaked in words like “gross,” “icky,” “yucky.” But where do such taboo feelings originate from? Not a single verse in the Torah, Bible or Quran — books revered by three billion followers of the three Abrahamic religions — prohibits cousin marriage, which were common in Jewish, Christian and Islamic history. The Bible even mentions various accounts of cousin marriages, such as Jacob and Rachel, Milcah and Nahor, and Jacob and Leah, in the book of Genesis. And please don’t quote the incest prohibitions listed in Leviticus 18. It never mentions first cousins.
Third cousins have the greatest number of kids. Also, third cousin marriage doesn’t seem to affect IQ being that Iceland’s average IQ is 101. I don’t even think anyone brings up a religious basis for first cousin marriage, just the deleterious effects of it are the reason why not to mention it’ll be someone you’ve most likely grown up with your whole life. Your family has a unique smell, which obviously evolved to make you not want to mate with your family. This shows that nature made it so that we don’t inbreed too closely, and that for fertility, third cousin marriage is best.
This is the ultimate argument made in support of banning cousin marriages. It’s so obviously wrong that “You don’t have to be an Einstein to figure it out.” In the evidence driven societies we have a different word to describe such claims: myth. Myths are best broken by data. The fact that 20 percent of global marriages take place between first cousins and most societies, including Europe and Canada, consider cousin marriages to be legal should give us a pause.
It’s fine guys!!! Einstein did it too!! I’m sure this is a logical fallacy though it escapes me at the moment. Just because someone who is extremely intelligent does something, doesn’t mean that it’s OK to do.
To conclude, the cause for the constant strife (not even getting in to any other external factors) in the Middle East is due to constant inbreeding depression, which dropped IQ, which led to more clannishness due to more cousin marriage, and more inter-group violence.
Third cousin marriages, as seen in Iceland, are fine, it has no negative effects on IQ and they are more fertile because of it.
I personally think a huge part of the reason for the current situation in Europe is obviously the high European altruism and a high rate of individualism. As you can see from the map above, the countries with the highest amount of individualism have the most problem with the ‘migrants’ and are also the most liberal and atheist. The collectivist countries obviously have a stronger religious component, which in Eastern Europe you see them pushing back harder against Islam. The same in Spain, and Southern Italy (also the Mafia said they will take care of IS). Those collectivist countries (or regions) push back harder because they have something to fight for, their religion as well as people, being that they are more collectivist than the individualist countries. This map roughly matches up to this situation in Europe.
Collectivist countries are clearly more religious than the clearly atheistic, liberal, socialistic and individualist Northern European countries.
The more collectivist countries are more clannish, due to religion. Those countries will push back the hardest, even harder than the individualist countries.
Genetic Similarity Theory
Genetic Similarity Theory is a theory, first though of by JP Rushton, that states that altruism is heritable. In Rushton’s beginning years in psychology, he began his research on altruism, having authored 2 books on the subject.
The theory itself holds that people will be more altruistic to genetically similar people than to people more genetically distant from themselves. European peoples are the most altruistic, having weathered the Ice Age for tens of thousands of years, leading to more group cooperation and more trust in the societies, that we still see today.
I have seen some people. like Jayman state that “Ethnic Genetic Interests Don’t Exist and Neither Does Group Selection”. That is so ridiculous, where do I start?
Well first off, we are genetically close to our friends, research shows that our close friends are as similar to us as 4th cousins. We also have altruistic behavior towards our friends, I would assume, because of genetic similarity. That same altruism for people with your genetics had our ancestors weather the Ice Age and led to the development of altruistic behavior and high trust societies.
We know that Europeans are the most altruistic peoples, so with that innate altruism, it obviously helped group selection in the Ice Age to select for more altruism, which led to high trust between them.
There are neurological reasons for having more altruistic behavior for your own people. To quote from the paper Oxytocin promotes human ethnocentrism:
Human ethnocentrism—the tendency to view one’s group as centrally important and superior to other groups—creates intergroup bias that fuels prejudice, xenophobia, and intergroup violence. Grounded in the idea that ethnocentrism also facilitates within-group trust, cooperation, and coordination, we conjecture that ethnocentrism may be modulated by brain oxytocin, a peptide shown to promote cooperation among in-group members.
Results show that oxytocin creates intergroup bias because oxytocin motivates in-group favoritism and, to a lesser extent, out-group derogation. These findings call into question the view of oxytocin as an indiscriminate “love drug” or “cuddle chemical” and suggest that oxytocin has a role in the emergence of intergroup conflict and violence.
There is a genetic basis for ‘racism’, it’s actually called human ethnocentrism, but that doesn’t stop people from creating new buzzwords in order to make a person appear like they’re unintelligent and barbaric for going against the hivemind of political correctness.
Now that we know the reasons for human ethnocentrism, let’s talk about the ‘selfish gene’.
George R Price, a physical chemist later turned science journalist, developed his theory with a math equation. He later had a conversion to Christianity and set out to disprove his theory. No matter what he did, people would take advantage of him. He later killed himself because he couldn’t disprove his theory.
Now, you may say that that disproves ethnic genetic interests as well as group selection, but, the Price Equation is still the widely held to be the best mathematical, biological and evolutionary representation of altruism.
In a paper in which Price was the co-author, he applied Game Theory to evolutionary biology. Game theory is a model that looks at relationships between people in a particular model and attempts to predict their optimal decisions. To quote from the paper he co-authored, The Logic of Animal Conflict:
Conflicts between animals of the same species usually are of “limited war” type, not causing serious injury. This is often explained as due to group or species selection for behaviour benefiting the species rather than individuals. Game theory and computer simulation analyses show, however, that a “limited war” strategy benefits individual animals as well as the species.
So we can see here, that conflicts between those of the same species are of ‘limited war’ and not causing serious injury. That is because of genetic similarity.
Price also stated that in the same way an organism might sacrifice itself to spread its genes, that same organism will sacrifice itself to eliminate those of the same species if it enabled closely related organisms to better spread their genes.
So, what Price stated right there, as well as his 2 papers, directly refute what Jayman says on this.
Altruism, ethnic genetic differences, and group selection all do exist within humanity, though at different rates in different populations.
Genetic Reasons for Human Migration
It’s always talked about in race realist circles what caused the migration Out of Africa and what gives us an urge and sense of wonder for adventure. Well, like with most things in life, there is a genetic reason behind it.
So I use this website called StumbleUpon and I was Stumbling in the Genetics section, and I came across this article, and as I was reading it, I knew that it was going to be rare in Africans.
And what do you know, I was right.
Seems like the gene developed around 40,000 years ago. It’s obviously not just a coincidence or ‘correlation doesn’t equal causation’ argument, as a whole bunch of research backs this gene, and specific alleles, to certain traits in humans, compared to migration, or lack thereof, around the world.
From some research, I found that the abstract of the article says: it’s linked to hyperactivity, novelty-seeking and risk-taking behaviors. Consistent with findings in animal studies was: having more exploratory behavior as well as increased speed and locomotion. Populations with a history of migration in the past 1 to 30,000 years will show the highest instance of having the DRD4 alleles. Those that migrated more miles have a higher rate than those that migrated less. Sedentary populations show a lower instance of the DRD4 allele.
The abstract also says “After compiling existing data on DRD4 allele frequencies of 2,320 individuals from 39 populations and on the migration pattern of these groups, we found that, compared to sedentary populations, migratory populations showed a higher proportion of long alleles for DRD4.”
A correlation of .85 was found with km traveled and rate of DRD4 allele frequency distributions, which support the hypothesis. Nomadic populations had a 10.4 percent higher rate of DRD4 long alleles than sedentary ones.
Here is a blog post talking about the DRD4-7 genes and how they are involved with dopamine levels in the brain and have to do with motivation and behavior.
It cites a researcher saying that the gene occurs in populations that migrated first and furthest out of Africa are more likely to have the gene.
Another blog talks about how Africans with the 4R allele stayed in Africa whereas those with the 7R left and explored the world.
Research has found that it’s easier for the 2R allele to mutate into a 7R allele than for a 7R allele to mutate back to a 4R allele.
So it’s thought that those who emigrated but remained closer to Africa, such as Asia, lost the behavior to explore and settled rather than explore the Americas (which Siberians did do, who eventually became Indians. I would assume that they would have a higher prevalence of this gene, being as they migrated to the Americas while the Africans stayed in Africa, as well as Indians being the furthest genetically from Africans, it also makes sense there). Also saying that those who emigrated to Asia had the 7R, but stayed and it mutated to the 2R over time.
It says looking at the global prevalence of certain allele frequencies, the 4R is more common in Africa, the 2R in Asia, the 7R in the Americas (mostly South), supporting the theory for the 7R allele being the cause for global expansion and positive selection.
Found this article talking about how the DRD4 allele is a role “in the escalation of substance use during adolescence and potential for an enhanced understanding of early-onset substance use.” and those with the 7R allele “Supporting the differential susceptibility to parenting hypothesis, the results suggest a greater preventive effect for youths carrying a 7-repeat allele”.
This NatGeo article says “Most provocatively, several studies tie 7R to human migration. The first large genetic study to do so, led by Chuansheng Chen of the University of California, Irvine in 1999, found 7R more common in present-day migratory cultures than in settled ones. A larger, more statistically rigorous 2011 study supported this, finding that 7R, along with another variant named 2R, tends to be found more frequently than you would expect by chance in populations whose ancestors migrated longer distances after they moved out of Africa. Neither study necessarily means that the 7R form of the gene actually made those ancestors especially restless; you’d have to have been around back then to test that premise with certainty. But both studies support the idea that a nomadic lifestyle selects for the 7R variant.”
All in all, this shows a genetic reason WHY the migration OoA began. It’s very telling that the DDR7 allele first arose when we migrated OoA.
