Race differences in intelligence: how research changed my mind to overcome the “all races are equal” dogma.

I grew up indoctrinated by political correctness. Like a large part of citizens in Western countries I was brainwashed: Races do not exist, all are equal. Saying anything different, saying that there are racial differences, is racism, a crime.

Read this, everything you need to know about scientific research about racial differences: RACE, EVOLUTION, and BEHAVIOR: A Life History Perspective, by J.P. Rushton

In school I heard disparaging remarks about Artur Jensen and other “unscientific” “dishonest” “cheating” scientists doing faulty research about race differences.

The Bell Curve by Richard Herrnstein and Charles Murray actually looked fairly convincing to me, but if even President Bill Clinton denounced it, there must be something wrong about it.

There always was some complex theory to explain away the IQ differences:

  • different culture
  • parental expectation
  • mother’s malnourishment
  • IQ measurements are racially and culturally biased

Adopted Children's IQ by Race

My opinion changed when I read about trans-racial adoption studies. That was the last drop that really disproved all these desperate attempts to explain away racial differences in intelligence.

“The best evidence for the genetic basis of race-IQ differences comes from trans-racial adoption studies of Oriental children, Black children, and Mixed-Race children. All these children have been adopted by White parents at an early age and have grown up in middle-class White homes.”

Chart 9 summarizes the results for Oriental children adopted into White middle-class homes.
Korean and Vietnamese babies from poor backgrounds, many of whom were malnourished, were adopted by White American and Belgian families. When they grew up, they excelled in school. The IQs of the adopted Oriental children were 10 or more points higher than the national average for the country they grew up in. Trans-racial adoption does not increase or decrease IQ. The three-way pattern of race differences in IQ remains.”

In plain English: adopted Asian babies grew up to be very bright, adopted black babies grew up to have low intelligence.

One more desperate argument that was posed to save the “racial equality” dogma:

They claimed “expectancy effects,” not genes, explained the pattern. They argued that the Black and White children were not treated the same. Even if parents took good care of their children, the schools, classmates, and society as a whole discriminated against Black children and this hurt their IQs. Because we expected Black children to do poorly in school, they lived up to our low expectations.”

Even that argument got promptly destroyed.  Rushton:

A special analysis of the Scarr study compared parents who believed that they had adopted a Black baby but, really, had adopted a Mixed-Race (Black-White) child. The average IQ for these Mixed-Race children was just about the same as for other Mixed-Race children and above that for adopted Black children. This was true even though the parents who adopted these Mixed-Race children thought their babies really had two Black parents.

That did it for me. It destroyed my ingrained indoctrinated beliefs that all races must be equal. It opened up my mind to the possibility that there could be racial differences.

Before we go on, may I stress a few more points

  • I have no axe to grind against blacks. I am not interested in proving that blacks are stupid or inferior. I am not a white supremacist
  • I have an axe to grind against dogmatism, blindness, stupidity. I have an axe to grind against the catholic church for repressing Galileo’s truth about the moving and revolving earth. And I have an axe to grind about political correctness repressing the truth, repressing research.
  • This site is about human stupidity versus truth and consciousness
  • Rushton, though much maligned, is not some crazy cook but one of the most prestigious research scientists to date: Rushton holds two doctorates from the University of London (Ph.D. and D.Sc) and is a Fellow of the John Simon Guggenheim Foundation, the American Association for the Advancement of Science, and the American, British, and Canadian Psychological Associations. He is also a member of the Behavior Genetics Association, the Human Behavior and Evolution Society, and the Society for Neuroscience. Rushton has published six books and nearly 200 articles. In 1992 the Institute for Scientific Information ranked him the 22nd most published psychologist and the 11th most cited. Professor Rushton is listed in Who.  Some of Rushtons scientific publications can be found on his University page: http://psychology.uwo.ca/faculty/rushton_pubs.htm

Summary of Racial differences

Racial differences summarized (J.P. Rushton)
Racial differences summarized (J.P. Rushton): Why does history show Africa trailing behind Asia and Europe? Why do Whites average between Orientals and Blacks in so many areas? Why do the groups with larger brains have lower rates of two-egg twinning? To know the answer you must look at all of the traits taken together (see Chart 1). The traits in Chart 1 form a pattern. No known environmental factor can explain all of them taken together. There is, however, a gene based explanation. The patterns make up what is called a “lifehistory.” They evolved together to meet the trials of life -- survival, growth, and reproduction.

Then of course, the non-scientific “evidence”, the hearsay, the anecdotal evidence, our daily experience, suddenly made sense:

The Whites who explored China were just as racist as those who explored Africa, but their descriptions were different from what they and the Arabs had written about Africans. In 1275 Marco Polo arrived in China from his native Italy to open trade with the Mongol Empire. He found that the Chinese had well built roads, bridges, cities connected by canals, census takers, markets, standardized weights and measures, and not only coins, but paper money as well. Even a postal system was in existence. All of these made him marvel when he compared the Chinese to what he saw in Europe and the Middle East.
Even though he was an Italian, proud of his people and well aware of the greatness of Ancient Rome, Marco Polo wrote: “Surely there is no more intelligent race on earth than the Chinese.”

In amazing ways, Rushton forms a coherent picture to make sense of all the racial differences shown in reasearch.  Some differences are biological and can not be talked away by simple psychobabble or sociology-babble.

In a few cases medical treatment and medication showed racial differences. which proves a real quagmire for race equality dogmatist. Should they talk away and hide the differences as racist and cause medical malpractice and suffering for black patients? Or should they accept the scientific facts and actively promote racial analysis of medical studies and see their beloved pet dogma undermined?

Rushton’s book sums up the relevant research. Please forgive me for always quoting Rushton, incessantly. Nobody can say it better, nobody summed up the entire field in a more concise and coherent manner then Rushton.

Many statistics in Chart 1 come from the United States, where Orientals are a “model minority.”
They have fewer divorces, fewer out-of-wedlock births, and fewer reports of child abuse than Whites.
More Orientals graduate from college and fewer go to prison.
On the other hand Blacks are 12% of the American population and make up 50% of the prison population. In the U.S., one out of every three Black men is either in jail, on probation, or awaiting trial. That is much more than the number who graduate from college.
Chapter 2 shows how this racial pattern in crime is found worldwide. INTERPOL Yearbooks show the rate of violent crime (murder, rape, and serious assault) is four times lower in Asian and Pacific Rim countries than in African and Caribbean countries. Whites in the United States and in European countries are intermediate. The 1996 INTERPOL violent crime rates clearly show this pattern: Asian countries, 35 violent crimes per 100,000 people; European countries, 42; and African countries, 149.
Chapter 2 also finds that Oriental children are slower to mature than White children while Black children are faster to mature. This is true for the rate of bone and tooth development and the age at which a child first sits, crawls, walks, and puts on clothing. Oriental children do not begin to walk until about 13 months, White children at 12 months, and Black children at 11 months.
Chapter 3 looks at racial differences in sexual activity. Orientals are the least sexually active, whether measured by age of first intercourse, intercourse frequency, or number of sexual partners. Blacks are the most active on all of these. Once again Whites are in between. These contrasts in sexual activity lead to differences in the rate of diseases like syphilis, gonorrhea, herpes, and chlamydia. There are high levels of AIDS in Africa, Black America, and the Caribbean and low levels in China and Japan. European countries again fall in between.
The races differ in rate of ovulation (Chapter 3). Not all women produce one egg during the menstrual cycle. When two or more eggs are produced at the same time, a pregnancy is more likely. So is the likelihood of producing fraternal twins (i.e., two-egg twins). The number of twins born is 16 out of every 1,000 births for Blacks, 8 out of every 1,000 births for Whites, and 4 or less for Orientals. Triplets and other multiple births are rarest in Orientals and highest in Blacks, with Whites in between.
Chapter 4 is about race and intelligence. Hundreds of studies on millions of people show a threeway pattern. IQ tests are often made to have an average score of 100, with a “normal” range from 85 to 115. Whites average from 100 to 103. Orientals in Asia and the U.S. tend to have higher scores, about 106, even though IQ tests were made for use in the Euro-American culture. Blacks in the U.S., the Caribbean, Britain, Canada, and in Africa average lower IQs — about 85. The lowest average IQs are found for sub-Saharan Africans — from 70 to 75.
Chapter 4 also looks at brain size. Bigger brains have more brain cells and this leads to higher IQs. The races vary in brain size. The Collaborative Perinatal Project followed more than 35,000 children from birth to seven years. Orientals had larger brains than Whites at birth, four months, one year, and seven years. Whites had larger brains than Blacks at all ages (see Chart 2). The data on adults in Chart 2 come from a sample of 6,325 U.S. Army personnel.
Chapter 5 asks whether differences in our brain size, our bodies and our behavior are because of genes, environment, or both. It also asks whether individual differences can tell us anything about race differences.

Chapter 6 discusses the gene based “life-history theory” I have proposed to explain the racial pattern in brain size, intelligence, and other traits. Evolutionary biologists call it the r-K scale of reproductive strategies. At one end of this scale are r-strategies that rely on high reproductive rates. At the other end are K-strategies that rely on high levels of parental care. This scale is generally used to compare the life histories of different species of animals. I have used it to explain the smaller but real differences between the human races.

On this scale, Orientals are more K-selected than Whites, while Whites are more K-selected than Blacks. Highly K-selected women produce fewer eggs (and have bigger brains) than r-selected women. Highly K-selected men invest time and energy in their children rather than the pursuit of sexual thrills. They are “dads” rather than “cads.”

Chapter 7 shows that the race differences in reproductive strategies make sense in terms of human evolution. Modern humans evolved in Africa about 200,000 years ago. Africans and non-Africans then split about 100,000 years ago. Orientals and Whites split about 40,000 years ago.

The more north the people went “Out of Africa,” the harder it was to get food, gain shelter, make clothes, and raise children. So the groups that evolved into today’s Whites and Orientals needed larger brains, more family stability, and a longer life. But building a bigger brain takes time and energy during a person’s development. So, these changes were balanced by slower rates of growth, lower levels of sex hormones, less aggression, and less sexual activity.

Why? Because Africa, Europe, and Asia had very different climates and geographies that called for different skills, resource usage, and lifestyles. Blacks evolved in a tropical climate which contrasted with the cooler one of Europe in which Whites evolved and even more so with the cold Arctic lands where Orientals evolved.

Because intelligence increased the chances of survival in harsh winter environments, the groups that left Africa had to evolve greater intelligence and family stability. This called for larger brains, slower growth rates, lower hormone levels, less sexual potency, less aggression, and less impulsivity. Advanced planning, self-control, rule-following, and longevity all increased in the non-Africans.

I realize that these topics are controversial and that readers will have many questions. Chapter 8 lists the questions I am most asked about Race, Evolution, and Behavior, and my answers to them.

Conclusion

Race is more than “just skin deep.” The pattern of Oriental-White-Black differences is found across history, geographic boundaries, and political-economic systems. It proves the biological reality of race. Theories based only on culture cannot explain all the data shown in Chart 1. The next three chapters describe the scientific findings on race differences (summarized in Chart 1) in greater detail. Later chapters explain why these differences follow such a pattern.

Neanderthal was so stupid that they engaged in hand-to-hand combat with big dangerous animals, which is one of the things that led to their demise. Humans killed from a stand off distance. It’s even doubtful that Neanderthal had speech and language.

    1.English has “extremely close correspondence with mathematical structure” because all the words tht have “extremely close correspondence with mathematical structure” are actually derived from actual languages with “extremely close correspondence with mathematical structure” such as greek and latin, because english in its self does not have “extremely close correspondence with mathematical structure” and ” logical constructs required to define axiomatic bases are not present” so take a chill pill

    There are other variable at play here. Black people suffered centuries of subjugation and institutional societal barriers to their progress and equality. Add to that people in many black communities experience feelings of hopelessness, cynicism about their chances at moving up in the world, less than adequate educational and personal development opportunities, and low expectations. Those factors have the ability to manifest in a variety of ways within someone, including as an apparent lower intellectual capacity. People who experience that life are very unlikely to live up to their potential.
    I’d like to remind you that white Europeans often described Native Americans as less intelligent. So we must also consider an intelligence bias. In other words, creating a measure of intelligence that favors one culture or race over the other. Sometimes this is intentional, sometimes an unfortunate accident, but very real either way.
    The question is, does your analysis hold up when we account for these variables by conducting the tests on people with more similar backgrounds despite the racial differences?
    Based on some of the research posted above, I don’t think so.

    Anyone that plays chess knows that it is not a particularly intellectually challenging game. However, Scrabble is a very intellectually demanding game.

    Recently, a pure black African won The World Scrabble Championships:

An intelligent person would look at myriad other variables instead of jumping to the knee-jerk conclusion that this guy just happens to be the only African capable of winning the championship, which is not at all plausible. An intelligent person would say, “hmm…if more Africans played Scrabble more Africans would win the championship.” The same is applicable to any field of endeavor or any accolade such as the Nobel Prize in the hard sciences.

    That’s an exquisitely simple deduction to make. But people of your ideological bent seem to have a rigid mental block that prevents you from recognizing the obvious. Rather you go fishing for ever more nonsensical means by which to explain away the inconvenient truths that disprove your ideology.

    To answer your question, I am Nigerian by heritage, although I was born in the USA. I don’t have a trace of white or Caucasian DNA.

    Now, let me give you a couple of examples of other pure black Nigerians who are much smarter than you and probably every other white person you know or will ever know:

    This Nigerian scored the highest GPA in the history of Johns Hopkins University:

    “A 22-year-old Nigerian student named Emmanuel Ohuabunwa has broke the record for highest GPA in the history of John Hopkins University after graduating from the prestigious school with a 3.98 GPA on a 4.0 scale. He received a degree in Neurosciences and he plans to continue his studies at Yale Medical School so that he can gain a degree in Medicine. He is also a member of Phi Beta Kappa, which is an honor society that boasts prestigious members that include U.S. Presidents, Supreme Court Justices and Nobel Peace Prize winners.”

    This Nigerian scored the highest GPA ever in Russia:

    “The Federal Ministry of Education on Wednesday in Abuja honoured Dr Victor Olalusi who scored 5.0 Cumulative Grade Point Average (GPA) in the Faculty of Clinical Sciences, Russian National Research Medical University, Moscow (RNRMU) in 2013, arguably the first in the world.”

    And guess who’s known as the smartest family in Britain. Yep, it’s a pure black Nigerian family:

    “Peter and Paula Imafidon, 9-year-old twins from Waltham Forest in northeast London, are a part of the highest-achieving clan in the history of Great Britain education. The two youngest siblings are about to make British history as the youngest students to ever enter high school. They astounded veteran experts of academia when they became the youngest to ever pass the University of Cambridge’s advanced mathematics exam. That’s on top of the fact they have set world records when they passed the A/AS-level math papers.”

    Admin,

    Yeah, women are shorter than men. So what? If you have a sample size of 10,000 women and 10,000 men, it is certain that the men will be taller than the women on average. Now, find me a credible scientist who will say that given 10,000 blacks and 10,000 whites, that the whites will be smarter on average.

    It is you who doesn’t understand statistics. It is indisputable that women are shorter than men. Are you trying to telling me that the idea that blacks are less intelligent than whites is also indisputable? If so, give me your sources. And by sources I don’t mean discredited quacks like Rushton who have been censured by the academic and scientific communities for fraudulent research and cooked up data. I mean credible mainstream scientists and academics. And if you are suggesting that the brains of black people are somehow less developed or less prone to intelligence, can you give me the precise science to support that? And I don’t mean pseudoscience.

    If, indeed, it is indisputable that blacks are less intelligent than whites, why do you and people like you spend so much time and energy trying to prove it? For some of you it’s a full-time job. After all, it should be self-evident if it were true.

    And as I’ve tried to get thorough to your undoubtedly thick skull, it is completely irrelevant who creates what. Societies have different priorities, different influences and different ways of life. Simply look at the history of Europe. Compare ancient Europe or Medieval Europe to their contemporaries. Can you identify a single ancient manuscript from Northern, Central or Western Europe? No, you can’t. That’s because they didn’t have writing until it was imposed on them by the Romans. Other cultures had been writing for thousands of years. Now, if Europeans were “superior” why couldn’t they figure out writing on their own even thousands of years after other cultures had done so? As you are positing that Europeans (Northern Europeans in particular) are smarter, we should expect to see evidence of this “superiority” throughout human history. But we don’t, do we? Just 200 years ago, Europeans still hadn’t made the connection between proper hygiene and good health. They believed that bathing was dangerous so they’d go entire lifetimes without ever taking a bath. What do you think spread the plague and made it so deadly? It was the unimaginable filth in Europe and the almost complete lack of hygiene. Mind you, other cultures, including African cultures, had figured out the connection between cleanliness and good health thousands of years before.

      You don’t really have a grasp of statistics. If some women are taller than me, or than most men, this does not refute that, on average, women are shorter than men.

      Also most statistics work on large groups. A large group of people under IQ of 90 will not perform like a large group of people over IQ 110.

    “Mixed kids have the average IQ according to race admixture. That is why most successful Blacks are mulattoes. Like Obama.”

    Wrong again as usual. There are countless pure black Africans that are smarter than Obama. I don’t even think you’re interested in facts or real science. You’re just a racist ideologue.

    Here’s what Richard Nisbett, a real scientist (as opposed to a deluded racist blogger) says on this topic.

    “About 25 percent of the genes in the American black population are European, meaning that the genes of any individual can range from 100 percent African to mostly European. If European intelligence genes are superior, then blacks who have relatively more European genes ought to have higher I.Q.’s than those who have more African genes. But it turns out that skin color and “negroidness” of features — both measures of the degree of a black person’s European ancestry — are only weakly associated with I.Q. (even though we might well expect a moderately high association due to the social advantages of such features).

    During World War II, both black and white American soldiers fathered children with German women. Thus some of these children had 100 percent European heritage and some had substantial African heritage. Tested in later childhood, the German children of the white fathers were found to have an average I.Q. of 97, and those of the black fathers had an average of 96.5, a trivial difference.

    If European genes conferred an advantage, we would expect that the smartest blacks would have substantial European heritage. But when a group of investigators sought out the very brightest black children in the Chicago school system and asked them about the race of their parents and grandparents, these children were found to have no greater degree of European ancestry than blacks in the population at large.

    Most tellingly, blood-typing tests have been used to assess the degree to which black individuals have European genes. The blood group assays show no association between degree of European heritage and I.Q. Similarly, the blood groups most closely associated with high intellectual performance among blacks are no more European in origin than other blood groups.”

      Your New York times link is shortened and thus dead.

      Nisbett, in typical social science fashion, posits that the color to IQ correlation is due to social factors. Scientists should do research to prove such statements, not just dogmatically state their opinion.

      US Army Blacks are selected for higher IQ, as the lower IQ people are EXCLUDED. From what I understand, half of Blacks do not pass requirements. Armed Forces Qualifying Test (AFQT) score. The AFQT score determines whether you’re qualified to enlist in the U.S. military. http://www.dummies.com/how-to/content/asvab-afqt-qualifying-scores.html

      a) The US Army rejects over 60% of Blacks due to low IQ. Thus in the army, the IQ of Blacks and whites do not differ much. The lower IQ Blacks are not admitted into the army

      b) Nisbett is a politically correct scientist who has been casting doubt on IQ research and always been debunked by Rushton.

      It is strange that Nisbett uses skin color and negroid facial features as variable. I think we do have DNA measures of admixture, nowadays.

      This would require to read Nisbett’s sources, and Rushton’s sources.

      And additionally, it does not explain the intellectual, professional, political failure of Blacks everywhere, from Detroit to Haiti to Africa.

    Yes. This is true. The differences of races cannot be denied. Races are different. However, that doesn’t mean that all black people are more stupid than Chinese, it just shows a general range in which their “level of intelligence” stands. However, we should all be treated equally, with no doubt.

    But by the way, has anyone seen any scientific evidence that mixed kids ( half one race, half another), are smarter than most other races, including east asians?

      I plan to write a basic statistics class. Men are, on average, taller than women. Does this mean all men are taller than all women? The difference in height of men and women is about 1 Standard Deviation, similar to Whites to US Blacks.

      Mixed kids have the average IQ according to race admixture. That is why most successful Blacks are mulattoes. Like Obama.

    yes, I agree that scientifically it is the foundation of an investigation- not necessarily the end result. You made a very important point in an earlier comment- averages should not be used alone. Variance and other measures are important as well (as well as additional research etc.).

    Also, the current “race” categories are incorrect anyway. They are continuing to find more information about how humans evolved (with some studies coming out recently). (based on various Indo-European theories and such) The studies suggest that races are more complex than originally thought.

    Also, to @Lee Ta E who said: “Noticed verbal altercation between the whites and blacks here. Therefore, it is without doubt that the Orientals are the most reserved, less offended and less affected due to their genuine intellect and superior mental capacity..lol”

    ………this is an ignorant comment considering the domestic history of the United States and recent “white supremacist” propaganda by the media (many think intentionally used to divide). I wonder how the orientals would respond if this type of propaganda was used against them.

    Additionally, orientals may not be as affected by THIS situation for the reasons described above, but I don’t recall the Japanese being kind to the Chinese during WWII. In fact, I hear Japan isn’t even too kind to those from South Korea….if we are talking about online comments I have seen numerous forums of orientals pettily complaining about whites and blacks.

    There are numerous cruel and/ or stupid things orientals have done. The point being, your comment it is biased, ill-reasoned, and unintelligent.

    yes correlation does not equal causation and yes correlation is a good basis to start an investigation, however it is absurd to treat correlation as the finding of the investigation

    @blackstonemonkey , you do have a point that correlation doesn’t equal causation, however correlation is still very powerful causal evidence when discussing the relationship between variables (assuming the experiment is a random, large, and well-designed).

    Blacks can absolutely make efforts to improve their iqs (if desired) based on any believed extraneous variables. Also, the fact that children of different parents have varying iqs shows the influence of nurture to a partial degree (at least) regarding iq score. I believe that effort and discipline can make a huge difference regarding iq.

    It is also important to remember that humans have different but important skills, and even if this article is proved to be true (regarding iq) all people have value and all people can work to improve.

    @Admin,where i am from, statistics is taught in school and is overwhelmly considered the easiest topic in maths. my arguement is not that blacks do not test low on IQ tests, it is that the reason is not genetics or atleast that there is no reasonable evidence to suggest so. in science, for a hypothesis to become a theory it should atleast pass the ‘if test’ which is what i was using, if a hypothesis fails even a single ‘if test’ it is discredited. So when you pass a theory you should also explain its discrepancies for that theory to be valid e.g. Newtons first law of motion states that “a body stays in its state of rest or uniform motion, unless acted upon by an external force” without the “unless….” part it is wrong, but that part is what completes it and make it 100% correct all the time. every scientific law and theory has its discrepancies which are expleined within that law, making the law, or theory valid, that is what social Darwinism elitists fail to provide in their IQ-race genetics hypothesis making it invaid, which i was trying to point out on my first post on 15 july when i wrote this “so whoever supports that blacks are genetically stupid, then they have to explain what is wrong with those few that joined mensa, are they mentally defective?”. Now the statement “women are shorter than man” is good bar talk, scientifically speaking it is flawed, the correct way to put it is to say: women are generally shorter from than men from similar gene pool unless they one X chromosome that ‘escaped silencing’ in which case they may be just as tall or even taller

    Interesting about the ancestry of modern Europe from around 5,000 years ago- the Yamnayans. These peoples were NOMADIC.

    “DNA from the remains of nine individuals associated with the Yamna culture from the border between Samara Oblast and Orenburg Oblast has been analyzed. The remains have been dated to 3339-2700 BCE. Y-chromosome sequencing revealed that one of the individuals belonged to haplogroup R1b1-P25 (the subclade could not be determined), one individual belonged to haplogroup R1b1a2a-L23 (and to neither the Z2103 nor the L51 subclades), and five individuals belonged to R1b1a2a2-Z2103. The individuals belonged to mtDNA haplogroups U4a1, W6, H13a1a1a, T2c1a2, U5a1a1, H2b, W3a1a and H6a1b. A 2015 genome wide study of 94 ancient skeletons from Europe and Russia concluded that Yamnaya autosomal characteristics are very close to the Corded Ware culture people with an estimated a 73% ancestral contribution from the Yamnaya DNA in the DNA of Corded Ware skeletons from Germany. The same study estimated a 40–54% ancestral contribution of the Yamnaya in the DNA of modern Central & Northern Europeans, and a 20–32% contribution in modern Southern Europeans, excluding Sardinians (7.1% or less) and to a lesser extent Sicilians (11.6% or less).[4][7][8]”

    Another interesting excerpt from a HBR article, this reminds me of what Caroline was commenting above regarding big picture thinkers:

    “ADD confers both disadvantages and advantages. The negative characteristics include a tendency to procrastinate and miss deadlines. People with ADD struggle with disorganization and tardiness; they can be forgetful and drift away mentally in the middle of a conversation or while reading. Their performance can be inconsistent: brilliant one moment and unsatisfactory the next. ADD sufferers also tend to demonstrate impatience and lose focus unless, oddly enough, they are under stress or handling multiple inputs. (This is because stress leads to the production of adrenaline, which is chemically similar to the medications we use to treat ADD.) Finally, people with ADD sometimes also self-medicate with excessive alcohol or other substances.

    On the positive side, those with ADD usually possess rare talents and gifts. Those gifts often go unnoticed or undeveloped, however, because of the problems caused by the condition’s negative symptoms. ADD sufferers can be remarkably creative and original. They are unusually persistent under certain circumstances and often possess an entrepreneurial flair. They display ingenuity and encourage that trait in others. They tend to improvise well under pressure. Because they have the ability to field multiple inputs simultaneously, they can be strong leaders during times of change. They also tend to rebound quickly after setbacks and bring fresh energy to the company every day.
    Executives with ADD typically achieve inconsistent results. Sometimes they fail miserably because they’re disorganized and make mistakes. At other times, they perform brilliantly, offering original ideas and strategies that lead to performance at the highest level.”

    Admin,

    They don’t play chess in Africa. Not because they’re not capable, they just don’t. I happen to be an African who grew up in the United States. I did play chess. And I cleaned the clock of every white kid in every competition. Get it? It’s all about culture, upbringing, what someone is exposed to, influences, etc. A child should know these things, but you don’t and you’re trying to pontificate on intelligence? Why are you even judging Africans on the basis European ideals and European standards that took thousands of years of trial and error for the Europeans to refine and perfect? Africans have been exposed to these things for a very short time. It would be like if the Ancient Romans walked into a village in Briton or Germany expecting the barbarians to instantly know how to build an aqueduct or the Colosseum. Thankfully, the Romans weren’t that dumb. Grow up, man. You’re embarrassing yourself.

    White nationalists, race realists, white supremacists, etc. tend to be the absolute dumbest people walking the planet. Concepts and ideas that are plain and easy to grasp absolutely elude you. It’s a great irony that it’s the dumbest whites who go around trying to proclaim their superiority. Intelligent, thoughtful whites stay away from this junk.

      Chinedu, I think I asked you before: tell me your exact ethnicity. Are you half white like Obama, or part East Asian? Did you have your IQ tested officially? You could be theo one in a Million top Black IQ. But the IQ that is one in a Million in Blacks is much more frequent in Ashkenazi Jews.

      Did you apply to Mensa? They could use Blacks, I don’t think they have many Blacks in Mensa.

      Why don’t Blacks play chess? It might not be natural for their lower IQ cultures to engage in such a high IQ pastime. You are very welcome to check if among US chess masters and Grand Masters Black are represented with over 10%. And what percentage white admixture those Grand Masters have.

      Can you find any support for your hypothesis that in the USA Blacks perform as good as Whites in chess? I would bet that is not the case, as IQ is highly relevant in chess skills.

    using mean IQ to justify genetic differences is like finding a cube of ice floating in a volcano then you dismiss it as insignificant because it is too small, which is stupid. finding ice in molten lava nomater how small would be the greatest discovery of all time since that would disprove the laws of thermodynamics , ice nomater how small cannot coexist with fire. in the same sense, if blacks are genetically stupid, then its impossible for any single one black to not be stupid. Since mensa has more than one black person, that one person is evidence enough to show that it is not genetic, ie they got the stupid gene but not stupid, which means the ‘stupid gene’ does not make you stupid in the same way that if you could show that an ice cube can coexist with fire, you would have disproved thermal equillibrium, it does not mater if the ice cube was only a few cubic pico meters

      @blackstonemonkey, I wish statistics was taught in school. Either you don’t understand statistics, or you are dishonest, or both. Women are shorter than men, I think there is no doubt. Thus all women are short (what nonsense, but that is your logic). So one tall woman proves that women are not shorter than men.

      I plan to post “statistics for Dummies”, so at least honest people understand the meaning of statistics. Unfortunately, politically correct anti-racists try to confuse people with such faulty logic.

      A very long post, claiming to debunk Rushton and Jensen. It describes Rushton’s theory very well in details. It needs detailed study to analyze the veracity. After years of serious study, I can not imagine a honest true rebuttal of Rushton. I have seen too many failed attempts, debunked by Rushton and others in their papers.

      The entire world wide religion of political correctness depends on Rushton being wrong. So they wonder why African IQ is so low, without explaining why there is no scientific progress from Africa, and why African states are the only ones in the world that don’t get out of poverty. As the APA American Psychologica Association states elsewhere, the low African IQ correctly predicts low life success.
