Leftist Lies Destroyed as Scientists Discover the Gene Which Causes Brain Size and Intelligence

Nearly 100 years of leftist lies and deception, which has claimed that intelligence is not genetic, has been destroyed by the science of genetics.

According to a new study, just published in the University of California Los Angeles (UCLA) newsroom, scientists have definitively found the genes which control brain size and intelligence.

Even worse for liberals, dozens of studies have found race differences in brain size,whether measured by MRI, endocranial volume, brain weight at autopsy, or external head size (with or without corrections for body size).

Most were carried out on the three major races of East Asians, Europeans, and Africans. Averaging all the data, the following figures have emerged: Brain size average for East Asians = 1364cm3; Whites = 1347cm3; and Blacks = 1267cm3.

The overall mean for East Asians was 17cm3 more than for Whites and 97cm3 more than for Blacks.

Since every cubic centimeter of brain tissue contains millions of brain cells and billions of synapses, the race differences in brain size help to explain the race differences in IQ.

The latest overview, billed as the “world’s largest brain study to date,”  saw a team of more than 200 scientists from 100 institutions worldwide collaborate to map the human genes that boost or sabotage the brain’s resistance to a variety of mental illnesses and Alzheimer’s disease.

Additionally, the study (also published in the journal Nature Genetics), found new genes which control “differences in brain size and intelligence.”

 “We searched for two things in this study,” said senior author Paul Thompson, professor of neurology at the David Geffen School of Medicine at UCLA and a member of the UCLA Laboratory of Neuro Imaging.

“We hunted for genes that increase your risk for a single disease that your children can inherit. We also looked for factors that cause tissue atrophy and reduce brain size, which is a biological marker for disorders like schizophrenia, bipolar disorder, depression, Alzheimer’s disease and dementia.”

Three years ago, Thompson’s lab partnered with geneticists Nick Martin and Margaret Wright at the Queensland Institute for Medical Research in Brisbane, Australia, and with geneticist Barbara Franke of Radboud University Nijmegen Medical Centre in the Netherlands.

The four investigators recruited brain-imaging labs around the world to pool their brain scans and genomic data, and Project ENIGMA (Enhancing Neuro Imaging Genetics through Meta-Analysis) was born.

“Our individual centers couldn’t review enough brain scans to obtain definitive results,” said Thompson, who is also a professor of psychiatry at the Semel Institute for Neuroscience and Human Behavior at UCLA.

“By sharing our data with Project ENIGMA, we created a sample large enough to reveal clear patterns in genetic variation and show how these changes physically alter the brain.”





In the past, neuroscientists screened the genomes of people suffering from a specific brain disease and combed their DNA to uncover a common variant.

In this study, Project ENIGMA researchers measured the size of the brain and its memory centers in thousands of MRI images from 21,151 healthy people while simultaneously screening their DNA.

“Earlier studies have uncovered risk genes for common diseases, yet it’s not always understood how these genes affect the brain,” Thompson said.

“This led our team to screen brain scans worldwide for genes that directly harm or protect the brain.”

In poring over the data, Project ENIGMA researchers explored whether any genetic variations correlated to brain size.

Project ENIGMA investigators also discovered genes that explain individual differences in intelligence. They found that a variant in a gene called HMGA2 affected brain size, as well as a person’s intelligence.

DNA comprises four bases: A (adenine), C (cytosine), T (thymine) and G (guanine). People whose HMGA2 gene held a letter “C” instead of a “T” at a specific location on the gene possessed larger brains and scored more highly on standardized IQ tests.

“This is a really exciting discovery, that a single letter change leads to a bigger brain,” Thompson said.

“We found fairly unequivocal proof supporting a genetic link to brain function and intelligence. For the first time, we have watertight evidence of how these genes affect the brain.”

  1. That's just your bias showing. You don't seem to account for culture. Also south asians score highly in wealthier nations.(not referring to just 1st gen. high iq migrants) It's not genes that's holding them back. I assume it's the same for SE Asians.

  2. Stumbled upon this article and found it interesting. Hope everyone realizes it's not about brain size that determine intent for success. Success is also in the eyes of beholder ranging from building a rocket to explore other galaxies or preserving your indigenous culture here on Earth.

  3. "A recurring caveat in this work is that the SNP effects are not expected to be constant in all cohorts. They may depend on a person’s age, environment, or other circumstances. We now know from ENIGMA2 that the top 8 loci associated with the volumes of subcortical structures were detectable consistently worldwide, even though each one accounts for < 1% of the variance. A later screen for age x SNP effects suggested that some genes have a greater effect on brain measures later in life (Hibar 2015), perhaps because they interact adversely with other biological processes or environmental stressors." (page 11)

    As you can see, there are 8 loci that influence the volume of human brain. However, each one of them accounts for less than 1% of variance in measures. Age, biological processes, environment and other factors may be considered as well. So, the arguments above are flawed.

  4. TV docco about that– posited simply getting off all fours and standing upright enables our brains to achieve more activity (burn more sugar) because there is always a lower air temperature due to small aircurrents measured with a handheld fan windmeter 4ft off the ground.

    Much depends on whether we believe in Darwinian Evolution. Its about the only metaphor we have to explain our origins. And Modern Neo Darwinism espoused by Richard Dawkins (small mutations create everything) has been utterly disproven by mathematicians, geneticists and physiologists. Ex 80pc of gene knockouts have no effect on a yeast organism. Cellular machinery works very hard to prevent mutations affecting outcomes.
    A further prob with brainsize comparison is that there are a few individuals who have 90pc of their brain missing and they function quite normally. Hydrocephaly I think its called. Confirmed in brain scanners.
    Further prob with brainsize is that mediums have proven contact with deceased people yrs after their brain has disappeared.
    Proven with the same statistical rigour used in medicine. Victor Zammit provides a free weekly email service detailing the 150yrs of research on this subject. Its astounding.

    Better than evolution seems to be that Genetic makeup contains many possibilties for an organism to flourish in a variety of environments. Lizards have completely changed their digestion from herbivore to carnivore in just 50yrs.It seems DNA reads the environment somehow like an antenna. It radiates visible light and likely reads and responds to visible light. Otherwise how do so many animals precisely match their background ? Intelligence might be affected by how easy it is to get food. And we do have far more capacity than we need for mere survival. And we bury our dead. No other animal does that. Conventional Evolution ( continuous mistakes producing everything) seems to be simplistic19th century materialism. The 70,000 yr question Why no evolution? Actually disproves continuous evolution. Too many creatures remain the same for hundreds of millions of years.

  5. If present-day Aboriginal Australians are the oldest population of humans living outside of Africa, then how come they have what is considered a very low IQ? If they descended from an early wave that left Africa about 70,000 years ago, (before the ancestors of Asians and Europeans) should not their society have evolved more by now, including their IQ level?
    Apart from inherited genes & brain size due to race, maybe the human brain (like a computer) works better in colder climates and worse when being in hot. I have no proof of this, just my own idea because when the summer comes and temperature rises my brain works slower. Of course you do not make a genius out of someone by just moving that person from a warm zone to a cold climate, but maybe you could gain lets say 5%. And in a long distance of time of lets say 70.000 years you'd might gain 25% and the rest might be differences in racial parameters?

  6. Another factor in development is emotional, assertiveness, namely studies reveal Euro babies put into an uncomfortable face down position on a pillow struggle rage and cry until they achieve a more comfortable position, while Asian babies tend to be more passive and enduring and put up with discomfort and struggle less.
    If you watch asian babies in pushchairs you notice they cry a lot less than caucasians. There must be some value in rage LOL

  7. I agree with one of the previous posters, that the Asian (I assume East Asian) and not the Low IQ South/South-Eastern Asians, have a marginally higher On Average IQ than Europeans (most would say insignificant).

    That said why is it, that most of the technological innovation/development (and our modern world and the industrial revolution) has been via European dominant societies. In fact even the East Asians accept, that they emulated Euro Societies/Western Civilization, to modernize (post WW2).

    I agree as the above poster mentioned East Asian IQ/Brain size may be slightly more than Euros. But I think going beyond an Agrarian/Proto-Industrial civilization, requires more than just IQ, it requires creativity and innovation (which I firmly believe is also mostly genetic). One thing I noticed with many East Asians (and some many high IQ southern Asians), having worked with many of them is they lack the creativity and innovation or Europeans/Westerners (on average).

    Much of their modernization has been via Emulating the West. I think they are very good at rote learning and passing tests, but lack the creative/adventurous/innovative spark, that Europeans/Westerners have. Just my 2 Cents!

  8. Facts are facts and should not open to dispute. However, many or perhaps most people want to ignore simple facts when it concerns differences between the races regarding brain size or intelligence but few people dispute other factors such as darkness of skin or average height.

    They become emotional and try to change the subject from simple facts to claims of racism, environmental differences, etc.

  9. The whole world has known about this differences always, but in this "free world" of ours there is actually laws against talk about it. Labeled as racism. The question will be what to do about is and what consequences it may have to have a large population of blacks in a civil society.

    Sterilization in a grande scale will not happen I guess. My hope goes to Chinese scientists that may find a DNA treatment for bringing the IQ up in surrten populations for the good and the bether for all in the world.

  10. You do realise that the difference in size between East Asian brains and White European brains is statistically insignificant don't you?

    In addition, it has long been recognised that East Asians are highly intelligent, therefore the findings in fact do correlate with the brain size/intelligence ratio.

  11. The fact that you responded by lashing out, rather than putting forth a contrary argument, reveals not the "fears" of white conservatives, but those of yourself (and other presumably white leftists who agree with you). But all studies aside, all one needs to do is look at history and the relative achievements of the races. Which societies are the least advanced? Obviously African societies. Which societies display the greatest products of the mind? It's a close call between European and Asian societies. But if one considers the purely mental quality of Asian cerebral achievements such as the development of one's "chi", as opposed to the intellectual (idea based) achievements of European societies, and the fact that through such development one can completely control one's mind, body and emotions, then clearly Asians deserve recognition for the greatest "achievement of the mind" in history. Also, if we are to subscribe to the prevailing scientific theory that all humans migrated from Africa, then using a "time on task" analysis, one can conclude that those that migrated first are likely to be the most evolved while those that are the last to migrate, or haven't migrated at all, are the least evolved. Given that some of the world's oldest civilizations are in Asia and Europe (esp. southern Europe), it stands to reason that those civilizations are among the most evolved from a scientific, migratory perspective. In the case of Asian migration, the fact that the distance from Africa to Asia is substantially greater than to Europe coupled with the exceptionally large Asian population (which indicates that these societies must have been settle a very long time ago), also provides evidence that these societies are the world's most evolved. And if we have the courage to put political correctness aside, we can conclude that if we did in fact evolve from ape-like creatures, then those that most resemble apes (Africans) are likely to be the least evolved. Finally, while we might not want to admit it, we all know from our own experiences in school & work that Asians are the most capable and Africans are the least capable, while at sports and other physical activities their respective rankings are reversed (and Europeans are somewhere in the middle). This the general rule. Are there exceptions, yes, but the rule itself is patently obvious, at least to those of us who value history, science and common sense.

  12. I am a "white racist" – a white person who recognises, like every non-white on the planet, that race differences exist and that they matter, and I know that most white people like me are perfectly aware that IQ tests and data on brain size both show that Orientals have higher IQ and larger brains on average than do white people of European ancestry. Facts are facts and since you acknowledge, as white racists, do, that Asians are smarter, then you must therefore acknowledge that there are different levels of average intelligence between the Races of Man. So to cut to the chase, blacks are less smart and their low IQ (not white racism) is what causes them to do less well in white societies than Orientals. You accept that, right, even as a possibility?
    Anyway, in my experience it is conceited liberal types that get upset concerning the Asian IQ data, since white liberals have this conceit that they are the smartest people and that it is their job to lift poor old non-whites up. It is the liberal ego that is hit.

  13. so what? It has long been known that different racial or cultural groups have different brain sizeson average.What has never been proven is that a bigger brain makes you intellectually superior, and this article does not prove it either. And aren't we mathematically talking about averages, and the scientists were identifying a gene for something else not intelligence?

    Makes me wonder why white conservatives aren't shit scared of smarter East Asians,if tthey believe this to be true. The thought of whites not being the most intelligent race on the planet, must be horrifying to arrogant white supremacists who might be taking out the trash for their East Asian overlords in a few centuries time. I am being tongue in cheek here, but It is good to know that some of them will be then have found a vocation to be successful at. Maybe though, you could marry an intelligent East Asian, and have kids that are more intelligent than both their parents. That of course won't happen because that would blow ideas of cultural purity and superiority out of the water.

    we should not be comparing brain sizes with each other, but comparing brains with penises. In the case of penises,it is not the size but whether you know what to do with it. There are plenty of people with big brain but do not know what to do with them. not to mention those guys who carry their brains in their penises…

    "The purpose of this study was to determine whether demographic and clinical factors are associated with a diagnosis of depression among persons with schizophrenia and to determine the association of depression with subjective quality of life. A consecutively admitted sample of psychiatric inpatients diagnosed with schizophrenia (n = 123) were assessed for depression and quality of life. Logistic regression was used to determine factors associated with a diagnosis of depression. Multiple regression analyses were used to determine the relationship between depression and quality of life. The odds of being diagnosed with depression were seven times greater in Caucasians than in African-Americans, and three times greater in persons who were ever married. Depression was significantly associated with reduced life satisfaction in Caucasians but not African-Americans."
