Race and IQ debate reignited

by Jonathan on April 26, 2005

From Eurekalert:

Black-White-East Asian IQ differences at least 50% genetic, major law review journal concludes

A 60-page review of the scientific evidence, some based on state-of-the-art magnetic resonance imaging (MRI) of brain size, has concluded that race differences in average IQ are largely genetic. The lead article in the June 2005 issue of Psychology, Public Policy and Law, a journal of the American Psychological Association, examined 10 categories of research evidence from around the world to contrast “a hereditarian model (50% genetic-50% cultural) and a culture-only model (0% genetic-100% cultural).”

…”Neither the existence nor the size of race differences in IQ are a matter of dispute, only their cause,” write the authors. The Black-White difference has been found consistently from the time of the massive World War I Army testing of 90 years ago to a massive study of over 6 million corporate, military, and higher-education test-takers in 2001.

“Race differences show up by 3 years of age, even after matching on maternal education and other variables,” said Rushton. “Therefore they cannot be due to poor education since this has not yet begun to exert an effect. That’s why Jensen and I looked at the genetic hypothesis in detail. We examined 10 categories of evidence.”

1. The Worldwide Pattern of IQ Scores. East Asians average higher on IQ tests than Whites, both in the U. S. and in Asia, even though IQ tests were developed for use in the Euro-American culture. Around the world, the average IQ for East Asians centers around 106; for Whites, about 100; and for Blacks about 85 in the U.S. and 70 in sub-Saharan Africa.

2. Race Differences are Most Pronounced on Tests that Best Measure the General Intelligence Factor (g). Black-White differences, for example, are larger on the Backward Digit Span test than on the less g loaded Forward Digit Span test.

3. The Gene-Environment Architecture of IQ is the Same in all Races, and Race Differences are Most Pronounced on More Heritable Abilities. Studies of Black, White, and East Asian twins, for example, show the heritability of IQ is 50% or higher in all races.

4. Brain Size Differences. Studies using magnetic resonance imaging (MRI) find a correlation of brain size with IQ of about 0.40. Larger brains contain more neurons and synapses and process information faster. Race differences in brain size are present at birth. By adulthood, East Asians average 1 cubic inch more cranial capacity than Whites who average 5 cubic inches more than Blacks.

5. Trans-Racial Adoption Studies. Race differences in IQ remain following adoption by White middle class parents. East Asians grow to average higher IQs than Whites while Blacks score lower. The Minnesota Trans-Racial Adoption Study followed children to age 17 and found race differences were even greater than at age 7: White children, 106; Mixed-Race children, 99; and Black children, 89.

6. Racial Admixture Studies. Black children with lighter skin, for example, average higher IQ scores. In South Africa, the IQ of the mixed-race “Colored” population averages 85, intermediate to the African 70 and White 100.

7. IQ Scores of Blacks and Whites Regress toward the Averages of Their Race. Parents pass on only some exceptional genes to offspring so parents with very high IQs tend to have more average children. Black and White children with parents of IQ 115 move to different averages–Blacks toward 85 and Whites to 100.

8. Race Differences in Other “Life-History” Traits. East Asians and Blacks consistently fall at two ends of a continuum with Whites intermediate on 60 measures of maturation, personality, reproduction, and social organization. For example, Black children sit, crawl, walk, and put on their clothes earlier than Whites or East Asians.

9. Race Differences and the Out-of-Africa theory of Human Origins. East Asian-White-Black differences fit the theory that modern humans arose in Africa about 100,000 years ago and expanded northward. During prolonged winters there was evolutionary selection for higher IQ created by problems of raising children, gathering and storing food, gaining shelter, and making clothes.

10. Do Culture-Only Theories Explain the Data? Culture-only theories do not explain the highly consistent pattern of race differences in IQ, especially the East Asian data. No interventions such as ending segregation, introducing school busing, or “Head Start” programs have reduced the gaps as culture-only theory would predict.

In their article, Rushton and Jensen also address some of the policy issues that stem from their conclusions. Their main recommendation is that people be treated as individuals, not as members of groups. They emphasized that their paper pertains only to average differences. They also called for the need to accurately inform the public about the true nature of individual and group differences, genetics and evolutionary biology.

What Dr. James D. Watson said is totally True.

The races do have different races.

Africans in usa have IQ of 82-85.

15-18 gap with whites of 100

Africans in africa have IQ of 70 in sub-saharian africa.

All facts known to the world via internet and google.

Google the truth. google truth.

Look at SAT scores from NSF: national science foundation.

Races do diifer in IQ scores.

Races differ in SAT scores. From the National science foundation

First,
Jewish people are the most intelligent. They win almost 40% of the Nobel Prize’s and they have a small population of only 14 million. So by far they exceed the other races in intelligence. The other races having huge numbers and such small contributions.

Second,
IQ tests, test intellectual conformity, not creativity and originality. This would explain the Asian high IQ’s. They as a people are the ultimate conformists.

In IQ tests there is typically only one answer to the problem. That problem being a social conformity to reason. But everyone knows that Genius’s and all the greatest developments in the world are not the product of conformity. Conformity never breeds creativity. We can see this in the lack of influence the Asian population has had on Science. China used to be called the “sick man” of Asia. Their population is massive and their contribution to innovation is almost nil. We can see this lack of originality in their adoptation of European philosophies, I.e. Communism.

Friedrich Nietzsche and other Philosophers have made critized Asian. Nietsche used the words “Pallid osification” to describe Orientals.

Pallid: lacking sparkle or liveliness, dull.

Osification: Process of becoming inflexible: the process of becoming set and inflexible in behavior, attitudes, and actions. Inflexible conformity: rigid, unthinking acceptance of social conventions.

The reality is Asian people have yet to understand that laws and rules are arbitrary. Europeans make the rules and Asian’s follow them.

It also doesn’t make sense that Asian’s are considered smart because of the fact that they have destroyed their own countries. This is due to over-population and their basic lack of enviromental understanding.

It is also common scientific fact that women who have many children are ignorant, and those who have less children are more intelligent. This has already been proven in studies. So it seems strange to say that Asians are smart when the obviousness of their backwards countries, and medieval lifestyle makes them contrary to that premise.

Europeans have the most advanced civilizations and every other race has yet to meet these levels other than the Japanese. The Japanese only being good at copying other people’s inventions and making them better. Other than that their original creativity is lacking as well. They took American cars and made them better. They took the German camera and made it better. And they took German steel and made it better. Otherwise the greatest advances still come from Europeans and Jews. Other than that the Orientals have yet to produce an Einstein or a Thomas Edison.

When it comes to Black people. It makes sense that they have low intellectual comformity, I.e. IQ tests. They are far too creative to be trapped in this unoriginal form of conditioning. You can tell their creative capacity in their athletics, music, dance, and the way they talk. They by far exceed the Asiatic races in these areas. Being better singers, musicians ect. Blacks far exceed Asians in emotive expression. In all of North America there is only one or two famous high-paid Asian actors.

Reality, Europeans rule the world and they have allowed others to exist only out of desire for economic bennifet. They, (Europeans) are also the physically strongest, winning the Strongest Man competitions again and again. And they have become the most effective hunters due to their neccesity for animal food stuffs in a northern climate with lack of vegetables.

The greater the conformity, the weaker the race. Thus we see the races as they are today. The wild animal being bred out of man, and the physically impotent, conformist thriving.

Otherwise “Group psychology” is the most destructive thing in the world. All these stereotypes are false when it comes to the individual. Individualism is the most important thing for this time. All countries, Relgions, groups need to dissolve for man to live in peace.

Hello,my name is Robyn King I am a 24-year-old female living in Los Angeles,California The United States Of America and I would say that all 100 percent japanese people both males and females all over the world with all 100 percent of them both males and females having and getting straight A+’s and straight A’s also all 100 percent of them both males and females having and getting 228 very high I.Q.s.The japanese race of people constantly rank at the very top of their education and have the top very best education system in the world out of the rest when it comes to education and they really always value extremely very high get extremely very high grades in school and in college and have an extremely very high excellent education rate.The japanese race of people and the rest of the oriental asian race of people are the smarest race of people in the world and they are really always known for that.It is really always extremely very rare to see an illiterate unintelligent japanese person.

Robyn… You are a fuckin idot. and E.C. aren’t most jewish people white? Or is there a new race? Jewish..?? Hmm..
Fuck Jews and Fuck Niggers..
All this article does is helps to explain black inferiority in the United States. While Asian may be the most itelligent of all races, it sucks for them because they are still a bunch of yellow backed slopes. I call it unconditional surrender. We vaporized over 100,000 rice eaters in WWII and now your tellin me that they are smarter? Not on that day.. BANG!!!
If only we could have dropped one or ten on Africa before we brought all of those niggres over here, the world would truly be fantastic!
Evidence is mounting.. Soon they will prove that homosexuality isa LEARNED behavior and all of the fairy faggot flower boys will have no excuse (i.e. “I was just born this way”) for wanting to fondle another mans hairy ball sack..
Fuck Niggers, Fuck Jews, Fuck Slopes, Fuck Spics, and Fuck Faggots..

Later

Your anger is unfounded..If people do not look or act the way you do, that is because we have variation in race, culture and sexuality. Life is about diversity and not about conforming to your perceptions of “the way things ought to be” Archie Bunkerstein

I always wondered “why” my asian classmates in L.A. did so well in school. I always wondered “why” my black classmates in Merced did so poorly..and “why” us white people and Mexicans were somewhere between the 2 groups REGARDLESS OF THE BEST BUSING OR HEAD START PROGRAMS IN EMPLOYMENT. It’s the genes, the genes, the genes….Black anger in America is not caused from perceived predjudice; rather, Black Anger stems from frustration because they cannot learn…

I find most of the people on here racist. Although I agree with a little bit of E.C.’s post. But I wouldn’t consider Jewish people to be the most intelligent, more of average. It depends on what traits you consider intelligent. I mean there’s street smarts and school smarts. It depends on what you’re talking about.

I myself consider imagination to be of superior intelligence. It’s just like what E.C. said, intelligence has its flaws in so many ways. I base it on originality.

It is said that man only uses 1/10th of his brain power. I believe we’re discovering the other 1/10th of it.

Jews didn’t invent anything until the industrial revolutin phenomenon occured in Europe. Caused by geographic competition in europe by several smal countries such as england and france, this phenomenon was instigated.China,separaed by the himalayas for most of the ancient period independently developed cannons, gear work machines, printing, paper, fire lances, siege engines, crossbows, south facing mechanical chariots, etc, flame throwers, conveyer belts that collected minerals fromthe mountains, If china was geographicaly where england is today,and it was constantly in competition with france and gemany technologically during the mid 1700s, it would no doubt be the most powerful european power and rule the entire world today.

The way i see it most of the ppl in here are racist or just speaking their mind. first let me start with Frank Avalon who the fuck are you saying what u saying u fucking mother fucker…. talking about destroying other places u mother fucker i wish i could find u and destroy you. Now going back to the topic… I believe that white people had a better chance in life than any other race. And im not saying they are the smartest 1 in the World example u are not going to compare some1 that had an Education with some1 that never been in school.. cause IQ tests are not just any tests they ask u things about school cultures etc… The most powerfull people in the world are those that can control their feelings and know how to handle life. White people are the weaker ones when it comes to mental problems, depressions, and other mental issues. so if thats the case if u so Intelligent why cant they control it? Black people are judge in their IQ because they dont think about school as much as Asians or Whites but that doesnt mean they are stupid, it means they are not into school beacause they focus on other things in life, money success etc.. and for those that think im wrong just holla and we can go on on,.

“it means they are not into school beacause they focus on other things in life, money success etc..”

How’s that working out for them? because I could swear they haven’t gained much money or success either. Now if you said STIs and jail sentences, that’s another story.
