Default Rushton on BW IQ

I really had expected different findings because of genetic mixing with whites (Check Rushton & Jensen in earlier paper:Rushton, J & Jensen, AR (2005) Thirty years of research on race differences in cognitive ability. Psychology, Public Policy, and Law. 11:2, 235-294.). I think Thomas Sowell (Sowell, T. (2005) Redneck Blacks and White Liberals. San Francisco: Encounter) has solutions that don't invoke stupidity.

Anyhow, from Phil Rushton on the Evo Psych List:

"There are four published articles just released on this issue from William
Dickens at Brookings, Charles Murray at AEI, and Profs. Arthur Jensen and
myself. Also a summarizing press release from me. I can send pdfs if anyone
contacts me by private email.

"Race-IQ Gap Remains; Findings Could Undermine Affirmative Action Policies

" PORT HURON, Mich., Nov. 9 (AScribe Newswire) -- Despite widespread
claims that the gap is closing between Blacks and Whites in educational
achievement and intelligence test scores, new research shows the 15-point IQ
difference is as large today as it was 100 years ago.

" A study published in the October 2006 issue of Psychological Science
showed the same Black-White IQ difference in large standardization samples
for four major IQ tests.

" The researchers reported on the Wonderlic Personnel Test, the
Kaufmann Assessment Battery for Children, the Woodcock-Johnson test, and the
Differential Ability Scale, which all combined to show a Black gain of less
than 1 IQ point over the last 30 years.

" The study's authors were veteran IQ researchers J. Philippe Rushton
of the University of Western Ontario and Arthur R. Jensen of the University
of California at Berkeley.

" Rushton and Jensen's article countered claims made in the same
journal by William Dickens of the Brookings Institute and James Flynn of the
University of Otago in New Zealand, who had presented data showing the
Black-White IQ differences narrowing by 4 to 7 points.

" 'Such claims have been routine over several decades,' said Prof.
Rushton. 'When the totality of the available evidence is examined, the
alleged evidence disappears.'

" ''The Black-White IQ difference in the United States has remained at
15 to 18 points, or 1.1 standard deviations, for nearly a century,' said
Rushton. 'It was first clearly established in 1917 by an analysis in the
U.S. Army of 23,596 Black draftees who had an IQ of 83 (vs. 100 for

" 'Military samples continued to show the same gap during World War II,
the Korean War, and the Vietnam War era,' he said.

The Black-White gap was also shown in 2001 in an analysis of
6,246,729 individuals from military, corporate, and higher education samples
published by Philip Roth and colleagues in Personnel Psychology.

Rushton and Jensen said their new study confirmed their earlier
conclusion that Black-White IQ differences are 80 percent heritable, an
estimate based on a review of the literature in the 2005 Psychology, Public
Policy, and Law. Rushton argued that given that the IQ differences were 80
percent genetic, no more than a 3-IQ point convergence would be possible.

Prof. Rushton said the results explained the under-representation of
Blacks in high IQ occupations.

Rushton also said the results could undermine affirmative action
policies as the US Supreme Court's 2003 decision on the University of
Michigan only being permitted affirmative-action on the assumption that
Black-White test scores were converging. That assumption has been shown to
be untrue.

Prof. Rushton said that his study was not the only one showing the
non-narrowing of the race differences. He pointed to Charles Murray's 2005
article in Commentary and the just published article by Murray in the
November-December issue of the Intelligence, which showed no narrowing on
the Peabody Achievement Tests.

James, here is my question about IQ as a measure of human intelligence. If I spend my childhood at home studying math, while you are out there playing football, and I end up scoring higher on SAT or IQ tests, does that mean I'm smarter than you?

My casual observation of how much effort the main races put in studying is, Asians 10, Whites 5, Hispanics 2, Blacks 1. Now if Asians were to put in one tenth of their current effort, I'm pretty sure they are going to end up scoring as low on IQ tests as blacks.

I think intelligence has a lot to do with how children are brought up by their parents, and different races have different cultures and child rearing practices. I do not like affirmative action either, but my reason is not genetics. I think it is high time that all these cultures (African, Asian, Hispanic, Arabic, etc) received an objective scrutiny.

[Wang asks:] If I spend my childhood at home studying math, while you are out there playing football, and I end up scoring higher on SAT or IQ tests, does that mean I'm smarter than you?
Think of it this way, Wang—if a white kid dedicates his life to being a great running back, the NFL is probably still going to pick the black kid over any white hype.

Tell you what, Wang—next Sunday tune in your Sony to an NFL game and, using some of that math you’ve been studying, observe the color of the various running backs and see if you can make any casual observations.

Fred, I fully understand your sentiment. Like I said, I'm against affirmative action.

But you didn't really answer my question. My point is, children who consistently spend more effort on math and science, either due to their own interest or more often parental enforcement, do well on these tests. If a culture dictates parental enforcement, however cruel it is, then that race will excell on these tests.

I do not believe the high IQs of East Asians as a whole has anything to do with their genes (individual cases may be different).

Sure, I suppose attributes such as work ethic, conscientiousness, morality, etc. will impact IQ, but then such things themselves are almost certainly influenced by genes.

Read the materials/scientists that JimB references, and if you’re still not convinced that IQ/intelligence is essentially innate, try teaching higher math (or conscientiousness) to kids at the low end of the bell curve.

Which explains why a woman, when looking for Mr. Right, Mr. Wang (it would have worked better if you had been a "Wong"), is really only interested in whatever is in his genes, and maybe his assets.

I read some studies done by professionals on Asian psychology. One of these was conducted in the 1970s by Canadian scientists. They tested six month old babies of Asian immigrants and found that they were passive compared to Western/white babies. Their conclusion: passivity is in the Asian gene.

I know for a fact that is not true. As I have detailed in The Confucian Mind, passivity which is typical of Asians is a direct result and intended effect of Confucian family training. Back then Asian parents started the training early, especially if they wanted their babies to behave in front of strangers, so as to save their “face”. Now the training is usually delayed about two years. So if the same test is done today, one would find passivity in three year olds but not six month olds.

The problem with these studies is that Western scientists generally have no idea of what happens in the family of non-Western peoples. There is a lot of systematic abuse built in these cultures, in the core cultural values. What scientists wind up measuring is the result of these abuses and mental conditions, not genes.

If popular culture of blacks is such that reading a book is deemed “acting white”, and ridiculed by peers, it should not surprise anyone that they do poorly academically on average.

I’m inclined to believe that intelligence is largely a result of intensive brain activities in childhood, which in turn is largely determined by the prevailing child rearing practices of a particular culture, though individual cases may vary.
