Science Confirms: Genes Determine Brain Size

Two scientific studies have definitively confirmed that genes determine brain size and intelligence—and that these are inherited traits, unaffected by environment.

The studies—both published in major scientific journals—conclusively disprove the lies put out by the race-denying “environmentalists” who claim that all races are equal and that all people are born “blank slates.”


The first study, published in the journal Molecular Psychiatry, titled “Shared genetic aetiology between cognitive functions and physical and mental health in UK Biobank and 24 GWAS consortia,” revealed a definitive link between cranial capacity—that is, brain size—and intelligence.


The paper, authored by an international team of scientists at universities in Britain, Australia, Germany, and the U.S., tested data from the U.K. Biobank for “shared genetic aetiology between cognitive functions and neuropsychiatric disorders and physical health.”

The study found “highly significant associations were observed between the cognitive test scores in the UK Biobank sample and many polygenic profile scores, including . . . body mass index, intracranial volume, infant head circumference, and childhood cognitive ability.”

In other words, the study found a conclusive link between higher intelligence and large head circumferences and brain volume.

The paper concluded that “the genetic associations between infant head circumference and intracranial volume with educational attainment and verbal-numerical reasoning are important in themselves, as are many other cognitive–mental health and cognitive–physical health associations.”

The second paper, published in the Royal Society journal Open Biology, discovered the actual genes responsible for bigger brain sizes after comparing the genomes of 28 mammals with different brain sizes.


The paper’s conclusion said that they had “identified a set of gene families whose sizes are positively associated with an expanded neocortex, providing new insights into neocortex evolution,” and that “identifying genomic signatures associated with the evolution of larger brain size and neocortex expansion will critically contribute to our understanding of the molecular pathways involved in the development and maintenance of cortical areas in highly encephalized mammals including humans.”

The papers confirm the accuracy of the science of racial craniology—which has been rejected by the race-deniers of post-World War II liberalism—and reinforces the reality of the existence of inherent, unchangeable racial differences in morphology and intelligence.

As detailed by Professor J. Philippe Rushton in his book Race, Evolution and Behavior, the average cranial capacity of Mongoloid Asiatics is 1,335 cm3, Caucasoids 1,341 cm3, and Negroids 1,284cm3—all differences, he notes, which are “highly significant within studies.”

What all these studies put together means is that brain size, intelligence, and cognitive ability vary from race to race, and are inherited and unaffected by environment.

These racial differences in intelligence are in turn the cause of differences in racial psychology and group racial behavior, as reflected in racial crime rates, social adaptability, and economic achievement.

The studies also provide conclusive evidence that the only solution to racial problems lies in complete physical and geographic separation, because the alternative can only lead to one thing: the overwhelming and destruction of the European type by other races.

The Biology of the Race Problem. By Professor Wesley Critz George. Commissioned by the Governor of Alabama in 1962, this seminal work on the reality of racial differences remains one of the most concise works on the topic. Starting with an explanation of the workings of hereditary, the author moves on to an in-depth discussion of the fundamental—and, as he points out, unchangeable—racial differences between Europeans and Africans in particular. Addressed in this volume are the standard topics of physical, psychological and intellectual differences. It then moves on to the important effects these differences have on society, providing an explanation for the ongoing and disproportionately high non-white crime rate, which, the author shows is rooted in an physical difference which creates different behavioral patterns. Click here for details.


    1. Cultural beliefs can turn the smartest people into imbeciles.

      This is why I say religion isn’t the problem, it is believing in things that not supported by the facts but rather on some ideology.

      1. Actually no, it wasn’t White people who brought them here “in the first place”. The Jews ran the entire worldwide slave trade, first from Europe and then from their huge operation based out of Newport, Rhode Island. Look it up. Without Jewish money, Jewish ships, Jewish sea crews and Jewish auctioneer houses (with a significant amount of help from African tribal kings selling off their own people) slaves never would have come here “in the first place”. In the Jews’ own literature, they brag about running the worldwide slave trade. The slave auctions in the U.S. were even closed on Jewish holidays. You can easily find this information online now. It’s well documented. Even Nation of Islam leader, Louis Farrakhan, published a two volume book series detailing it all, called The Secret Relationships Between Blacks and Jews, with reprints of lots of ads from the Jewish slave trader companies. It’s a massive scam how Whites are blamed for slavery.

        1. Well said Bell1. The jew is not white. The jew is behind some of the worst atrocities of humankind, from slavery to wars and all in between. Send the jew to israel with his muslime brothers.

        2. And it goes back a lot further. If you look into the matter with some scrutiny you are very likely to come to conclusion that all the islam slavery since 7th century on was jew controlled.
          Judeislam –
          Being thrown out of every country in Europe for treachery, pimping, usury, human sacrifice, paedophilia and a whole lot more, certain people were looking for means of revenge. Alas, their numbers were far from sufficient to do something about it, they needed “useful idiots” to do their bidding for them. Opportunity arose when they came across a madman who they befriended and encouraged. He was already a highway robber, murderer, paedophile and lot more so they were really soul mates. As they were incredibly good at infiltration they usurped leading roles in new movement that they helped to kickstart and through manipulation of the “prophet” and his followers (band of highway men) they decided to exact revenge on Europe and north africa. The rest is history. Whole 1400 years of murder, rape, slavery, child abuse… If you compare Quran and Talmud there is very little difference – kill Kafir, kill Goyim, sex with children – no problem etc. etc. So, they acquired an army that has in truth waged their revenge and desire to destroy (white) Europe ever since (now also coming to you friendly neighbourhood in US). Due to their excellence in subterfuge and infiltration over that period they have also managed to infiltrate all the royal houses of europe and all the highest positions in p[politics, law, banking and commerce and through banking managed to take over all the central banks causing all the countries to be forever in debt. As time went on there was increase in resistance to them (guess arabs have started seeing that things are not what they seem) and they now needed another lot of “free willing slaves” to sort it out. So they found perfect servants in large western country that they corrupted and that is now fighting all their wars in middle east. And, kafir/goyim are still mostly asleep.

  1. Quite right we are all born with a brain that is “a blank slate”!

    Difference is that the brains of Africans & some others remain blank!

  2. But how does this explain intelligent blacks. I’ve heard they can open coconuts by dropping them on a rock.

  3. I don’t understand why we can’t defend our human right to protect our own European culture, traditions, religion, ethnic identity and ancestral homelands, according to the United Nations Declaration of the Rights of Indigenous Peoples, without trawling around for biological evidence to support our rights, as if only “supremacy” gives us legitimacy as “Ethnic Europeans” = “Caucasians”. It seems to me that it smacks of desperation, and brings our legitimate rights into disrepute. We’re always hearing how Oriental & Indian Subcontinental students are more intelligent than our own schoolchildren, getting higher grades and becoming lawyers & doctors, the better to seize control and wipe us out. Does that mean we should welcome them as honorary members of our European tribes, and kick out our own poor boys, whose school grades lag far behind, thanks to decades of Marxist Subversion? It’s not about intelligence or superiority—it’s about humans preferring to live with their own tribes.
