To say that one side does not have any proof, according to you, does not in itself merit that you must believe the other side as true. That said, there can be no hatred or racism for asking such questions... or perhaps it is in the eye of the beholder?
    Thunder, is this going to be ignored?

    I have made no assertions. The only one who needs to provide evidence is those who make assertions.

    Yes a test like that would show that IQ is higher; but the findings are confounded by socioeconomic class - what is better is an adoption study (which someone has already posted evidence of .. see above posts on this page or the previous one) - even then, if all that was tested were IQ, it would have its shortcomings as there are more than one intelligence tests (as we've mentioned)

    can someone please post a link to the actual adoption study?

    if 1,000 black babies were adopted at birth by white upper middle-class parents, and yet scored lower than their white counterparts on IQ tests, that would be interesting.

    i would love to see such a study.

    EDIT: I personally believe that African-American culture is infected by a disease called "self-destruction" & "self-regression". They actually encourage others NOT to succeed educationally & intellectually. I have seen it, heard it, and experienced it in my public school years in NYC.

    I believe this cultural phenomenon is responsible for these lower IQ scores.

    Evolution didn't create humanity So no.

    Probably because, unlike us, he has a Nobel Prize for discovering DNA, and his other contributions. He has a bit more experience.

    Interesting .. it did not do that when I clicked on it .. wierd

    Anyway .. I'll just quote mbig .. see below:

    Medical Research News
    26-Apr-2005

    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)."

    The paper, "Thirty Years of Research on Race Differences in Cognitive Ability," by J. Philippe Rushton of the University of Western Ontario and Arthur R. Jensen of the University of California at Berkeley, appeared with a positive commentary by Linda Gottfredson of the University of Delaware, three critical ones (by Robert Sternberg of Yale University, Richard Nisbett of the University of Michigan, and Lisa Suzuki & Joshua Aronson of New York University), and the authors' reply.

    "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.
    [.....]
    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.
    [.............]
    I have yet to check if this is a peer reviewed article (it may not be as most researchers and achademics would not want to touch the subject with a 50 ft pole) ..

    Even an adoption study would add the new variable of the effects of adoption. Intelligence tests, IQ or otherwise, are very difficult to use as objective measurements of intelligence and mental capacity.

No one in this thread has argued that human populations are identical. Therefore, the existence of differences in narrow, highly-specific areas is irrelevant to the broader question.
    Evidence abounds which invalidates your liberal creationist assumption that all of humanity has an identical intelligence profile. There is absolutely no scientific basis upon which we should presume that some creationist nonsense is in play within the human species. The quick rise and sweep of lactose tolerance points to how quickly an advantage which is used within its environment can spread through a population.

    The evidence in support of variance in intelligence is so damn broad it's amazing to behold and all of the different lines of evidence reinforce one another and all of the extremist environmentalist determinist explanations are not able to account for the variance.

    There are plenty of people with Nobel Prizes for important scientific discoveries, why not pick them? What's so special about Mr. Watson?
