Jewish IQ is usually stated to be one standard deviation above that of Gentile whites, which is about 115. Some estimates are a little lower, some a little higher.

This is Half Sigma‘s breakdown of what this would mean in different IQ groups.

The real breakdown is actually a little different because Jews have a much wider range than whites Gentiles (who in turn have a wider range than Asians). Jews, despite having a higher average IQ, are also more likely than European-Americans to score at the lower end. But in the genius range, they are even more dominant. In the 1950s, New York City conducted a study which sought to find teenagers with IQ of 170 or above. Out of 28 students they found, 24 were Jewish.

A group with a narrow range like the Asians may have a high average IQ, but produce very few Nobel Prize winners. Almost all their people are either average or above average, but few are geniuses or incapable of graduating from school. Jews are the direct opposite. Many Jews have a low IQ, but the reverse side of the coin is the high proportion of Jewish geniuses.

Supposing that Jews are 2% of the population of the United States, and Jews have a median IQ of 115, and gentiles have a median IQ of 100, and both groups have a standard deviation of 15, the following chart shows the percentage of Jews at various IQ breakpoints:

Gentiles Jews
Entire pop. 98% 2%
IQ > 100 96.7% 3.3%
IQ > 115 94.0% 6.0%
IQ > 130 87.5% 12.5%
IQ > 145 74.4% 25.6%

Jews, despite their tiny population, would naturally be a much larger percentage of people in careers that require high IQs. This would be even further distorted if Jews had a cultural tendency to prefer certain types of careers over others, such as writing over hard science.

Writing Hollywood screenplays is a very highly g-loaded task, thus Jewish people comprise a very high percentage of screenplay writers. Stand-up comedy also seems to be highly g-loaded.

With the exception of folk rock, pop music is not so highly g-loaded so Jews aren’t as disproportionately represented among pop musicians.

Just as there’s not a white conspiracy keeping blacks from scoring well on the SAT, there is not a Jewish conspiracy keeping gentiles from writing screenplays. It’s just about the distribution of IQ.

Now take a look at Arthur Hu’s Jewish Spectrum.

Genetic Clusters February 28, 2009

This is so important that I decided to make a special page and place it at the top. Were I writing a book, the following information would’ve been chapter one.

Liberal Lysenkoists who deny evolution (or at least claim that all evolution magically ended in human beings 100,000 years ago and humans stopped genetically adjusting to their environment) tell us to believe them and not “our lying eyes” when it comes to the existence of races. According to them, races don’t exist because there is no one gene for a particular race (the same rationale is given to argue that sexes also don’t exist).

Of course there would be no gene for race. What purpose would that serve? To mark someone as deserving to get affirmative action?

One must understand how races (and species) develop.

At first, there was just one little thing that was able to reproduce itself. It was the original gene, the original form of life. Slowly it multiplied and spread. Under different evolutionary pressures, the new organisms developed differently.

Eventually there were enough differences that different populations could be classified as different species. Species don’t have a genetic mark that says, “dog”, “cat” or “monkey”. There are just differences and if differences are large enough, we classify populations as being members of different species.

Sometimes species would separate from one another. If the separation lasted long enough, such as between chimps, gorillas, humans and other apes, new species emerge. But if the genetic separation isn’t as long, other classifications emerge. Among dogs, we would call those groups breeds. In humans, we call them races.

There are other classifications of life, of course: Genus, (Biological) Family, Order, (Biological) Class, Phylum, (Biological) Kingdom, Domain. That will not be a major concern of my writing as I will focus strictly on human beings.

When some humans left Africa, they faced different pressures than before. Dark skin was no longer an advantage but rather a disadvantage. In Northern Asia during the Ice Age, it was advantageous to have a layer of fat spread evenly throughout the body, so the Mongoloid people acquired this quality, giving them a yellowish color, though their skin is itself not significantly different from that of Caucasians.

Slowly but surely populations adjusted to their evolutionary pressures. Nobody acquired a genetic stamp for their race. But what they did get is a set of qualities, what scientists call a genetic cluster.

It is true that you cannot look at one gene and know the person’s race and ethnicity. But you can look at a cluster of genes and tell with certainty what race the person is, and within the race, what is the person’s ethnic group and at times even what part of the country his ancestors lived in.

Without getting too technical with scientific explanations (those will come later, but I am just trying to establish the basics for now), you can think of genetic clusters in the following manner: curly hair does not in and of itself prove that the person is black. A person of any race, and in particular a Caucasoid, could have curly hair. A Caucasoid may have thick lips and even somewhat dark skin. Any one of these does not prove the person to be black. But when you see that a person’s hair is curly, his lips are thick, his skin is dark, his bone, cranial and dental structure is like most other blacks, and so on, so forth for hundreds and even thousands of different qualities, you realize that the person can only be someone of African descent. You know this just by looking at a person. Geneticists know this by looking at a person’s DNA.

Any single quality doesn’t prove the person to be of a particular race, but hundreds of qualities create an unmistakable cluster where even if the person is different from his race in one or two ways (such as an albino African who has light skin), we can still know the exact race of the person.

Similarly with genes: any gene could potentially be found in any population. But a cluster of genes will give you a certain answer.

Within each race, there are further divisions. White Scandinavians are different from white Mediterraneans. A further division is again possible: Scandinavians who are ethnic Norwegians are somewhat different from ethnic Swedes.

The closer one gets, the less differences one sees. Thus, Swedes may be different from Norwegians, but not as much as they are different from Italians. And the differences with Italians are less than the differences with Koreans. The differences with Koreans are less than with Zulus.

The reason is the time of separation into different groups (the later the separation, the fewer differences) and the amount of gene flow back and forth.

Whites separated from Asians later than from Blacks, so the differences aren’t as stark when it comes to everything from skin color to IQ.

So why are races determined at a particular level?

For one, races have common ancestors much later with each other than with other races. All humans descended from one woman who lived 140,000 years ago. This is what makes us part of the same specie.

All Caucasoids – Europeans, North Africans and Middle Easterners – descended from 7 women who lived 20,000 to 30,000 years ago. This is what makes all Caucasoids part of the same race.

Almost half of Ashkenazi Jews came from 4 women who lived in the last 1,000 years. This is what makes them part of not only the same ethnic group (the Jews), but the same group (Ashkenazim) within their ethnicity.

It is obvious that people who have a joint descendant 1,000 years ago will exist fewer differences among themselves than they would with a person with whom they share an ancestor all of 140,000 years ago. I will explain this in great detail in the future for those who are unconvinced.

The second explanation is that ethnic groups of the same race tended to live in relative proximity to each other, which allowed for some gene flow. While the European gene flow into the Ashkenazi Jewish community was only 0.5% per generation until the 20th century, European Jews still wound up with an average of 40% Gentile genes. Whether through marriage or rape by invading soldiers, ethnic groups mixed. Germany, for instance, invaded Russia in 1941 and proceeded to rape and have sex the local women. Four years later, the Soviet troops were in Germany, raping and having sex with the local women. This exchange of genetic material is as long as mankind, probably even longer.

There was some inter-racial mixing too, but nowhere near as much, with exception of places such as the United States where almost all descendants of slaves have at least some Caucasian blood.

Therefore, the greatest differences are from race to race. One for example may mistake a Swede for a Norwegian, or in some cases a Swede for Jew, but neither a Swede, nor a Norwegian, nor a Jew, nor any other Caucasoid may ever be mistaken for a Zulu, even if the Zulu is an albino and the Swede/Norwegian/Jew has curly hair.

Likewise, a Zulu may be mistaken for a Shona or a Kikuyu, but never for a Korean.

The existence of biracial or biethnic people does not disprove the existence of races and ethnic groups. If you mix a German Sheppard and a large Poodle, the result will be a mixed breed dog. It will not, however, prove that dog breeds don’t exist. The same is true for human races.

Just as genetic clusters can prove that you are a member of one race, they can prove that you are a member of multiple races or multiple ethnicities.

This is an oversimplified explanation, but one that should serve as an introduction. In my future entries, I will explain what the specific differences are, which haplogroups are associated with which ethnic and racial groups, and other information that will fill in any blanks left out in this introduction.

But for now just remember: just because there’s no one gene for race, does not mean that races don’t exist. There is no one gene for any given specie, and that doesn’t mean that we as humans are no different from gorillas and tigers. It’s not one gene, it’s many genes.

Races developed not because one magic gene popped up inside your body, but because of tens of thousands of years of evolution made you different from a person whose ancestors lived on another continent. And it is those differences, taken together, that make you part of your race, your ethnicity and your sex.

Why Study Jewish Genes? February 27, 2009

The blog will hopefully deal with a lot of different ethnic groups. Right now I am beginning with Jews and consider such study essential.

There are several reasons for this.

For religious reasons and due to anti-Semitism (such as segregation into the Jewish ghetto and the Pale of Settlement), Jews have been isolated genetically from other populations. Even when a Jew married a Gentile, the children were more likely to join the dominant majority rather than a persecuted minority. The lack of outside genetic inflow makes Jews a gold-mine in the study of ethnicity.

Jews are also distinct in several ways. Ashkenazi Jews also score the highest IQ of any ethnicity, with estimates ranging from 107 to 117 (half to full standard deviation). On the flip side of the coin is the lack of Jewish athletes, false myths about the Golden Age of Jewish Athleticism notwithstanding.

It is also less taboo to discuss Jews than others. Jews have a higher IQ than Gentiles passes much easier than whites have a higher IQ than  blacks.

And finally, while rank and file Jews usually acknowledge, at least in private, their intelligence and lack of athleticism, it is also the leftist Jews such as Stephen Rose, Gerald Dworkin and Richard Lewontin who’ve led the offensive of Lysenkoism (genes don’t matter, one can always adjust to become Albert Einstein or Tiger Woods) against evolution and genetics.

The funny thing is that there’s more information on Jewish genetics than on anyone else.

And to answer the question that I will surely face as to whether I am “some kind of Nazi” for writing about Jewish genetics: No, I am not a Nazi. The Nazis made it illegal to study intelligence differences because Jews outscored the Aryans. Sure they misused science in other ways. But that some people misuse science and turn it into political pseudo-science isn’t a reason to suppress the spread of legitimate information.

The second question I expect is that Jews aren’t a race or an ethnicity, but a religious group. This is false. Jews are both, but because the religious group and the ethnic group overlap more than 90% of the time, many English-speakers do not realize that there is a difference. In the Hebrew language, however, there are two words for it: ivri (Hebrew), meaning ethnic Jew and yehud (Jew), meaning a believer in Judaism. For obvious reasons, I will be concerned with Jews as an ethnicity rather than religion.

The Study of Race and Ethnicity February 27, 2009

Races exist. and so do ethnicities within races. It’s that simple. Yes, ladies and gentlemen, the Emperor has just been pronounced naked.

You don’t have to believe me, you can see it yourself. Many may fall for the Politically Correct dogma that tells you not to believe “your lying eyes”, but have no fear of your own common sense.

Race isn’t about skin color. A black albino isn’t part of the Caucasian race. Race is the result of tens of thousands of years of evolution, and it effected everything about you: your nose, your hair, your hormones, your brain, your disease predisposition. Those telling you not to believe “your lying eyes” tell you that evolution only effected the things you can see such as hair and skin. That is only because they cannot lie and tell you that skin color, nose shape and hair texture is the same since you can see every day that it really is different. But the politically correct tell you that everything you can’t see is the same. Does that seem believable? Why would evolution change your hair, but not your hormones? Your skin, but not your brain? What sense does that make?

Studies of course show that there are differences between races and ethnicities, even for those qualities one cannot see. These differences aren’t universal, but a cluster of qualities (and genes) will show a person to be within a particular race and ethnicity. A white person may have curly hair. That doesn’t make him black because all his other features will be more consistent with the Caucasian race.

Nor is ethnicity only about one’s citizenship. A Russian living in France is still an ethnic Russian and not an ethnic Frenchman. He may be loyal to France, but he will still have Russian DNA, and therefore he will look Russian, he will have predisposition to diseases common among Russians, and so on.

Environment surely matters, but it’s not everything. Your genes matter more than environment, as studies on separated identical twins as well as unrelated children adopted by the same parents have shown.

This will be the blog that will document just such studies.
