Repost from the old site: There is some pretty exciting news coming out of the race-IQ studies lately, especially a new study by Flynn and Dickens (F & D henceforth) that seems to show that younger Blacks are closing the ominous Black-White IQ gap. Traditionally, this gap has been about 15 points or so. But that does not necessarily mean that Blacks are dumb; instead, it means that on average they are less intelligent than Whites. This is on the type of intelligence that is measured on IQ tests, that does seem to be correlated with many things, including life success. The various attacks against IQ tests have pretty much all been shown to be worthless, and no test has yet been made in which the typical racial delineation is not present. Culture-fair tests score about the same as culture-loaded tests. IQ is indeed a reliable metric of pure brainpower, even as measured by such things as reaction time. On the other hand, it is not necessarily correlated with social skills, certain subtypes of intelligence (Blacks outscore all races on verbal memory – think rappers), musical or artistic skills, “common sense”, “street skills”, etc. As I noted in another post, the Flynn Effect has shown that IQ’s have been rising in the West, and even in some parts of the 3rd World, for about 50 years now. There is no way that genes operate that fast in the human race in the way it is currently structured. So the notion that IQ is all or almost all genetic can be safely tossed aside – otherwise we would not be seeing this huge rise in IQ scores. All IQ’s in the West have been going up about 3 points per decade from the early 1940’s to the early 1990’s at least. So that means that if White IQ’s had stayed the same during that period, Blacks and Whites would currently be tied for IQ. Since Black IQ’s have risen 15 points over the past 60 years, it becomes increasingly difficult to call Blacks “stupid”. Furthermore, an 85 score (the Black average) now is a full 15 points higher than an 85 score 60 years ago. F & D’s paper discusses various reasons why IQ’s might be rising. What does the F & D’s paper mean? It means that even while both Black and White IQ’s have been rising, Black IQ’s have been rising faster than White IQ’s. The main difference in F & D’s work and that of their detractors is that F & D only used standardized samples, which have become more available and of better quality in recent years. Even including the nonstandardized results that they excluded yields a Black score of about 90.5, which is about what they found in the standardized tests. Bottom line, F & D found that young Blacks gained 5-6 IQ points over young Whites during the last 30 years. Even including less quality tests gives the same result. Black-White gaps differ by age for unknown reasons. According to F & D, Black IQ is 98.4 at age 4, 92.5 at age 12, 92.4 at age 14, 90.0 at age 18 and 86.4 for 24 yr olds. By age 24, the familiar 15 t gap is back with us. F & D’s paper has been criticized by J. Philippe Rushton and Arthur Jensen (R & J henceforth), two authors who have long argued that the gap is immutable. Both have taken money from The Pioneer Fund, which is an openly racist eugenics organization founded by a US Nazi sympathizer. Not that that matters. We need to look at their science. Even R & J argue that Blacks have closed the gap by 3.44 points, so I am not sure what they are arguing with the authors about. In a response to R & J, the authors use Jensen’s own data to point out that R & J’s own data shows a Black rise of 5.25 IQ points for young Blacks. They also note why they did not use several tests, an argument that has been used to say that the authors cherry-picked their results. The 1983 K-ABC data was rejected due to too great a variance in the scores. The original author of that notion was none other than Jensen himself. The authors excluded Woodcock-Johnson results; they quote an expert saying that the sample was not representative of the US population, and the subsample even more nonrandom. The authors analyze R & J’s rejoinder to the paper and find that R & J found an IQ of 89.88 for Black 15 yr olds. This is even higher that what the authors themselves found. It is hard to understand what R & J are arguing about, as their data tends to confirm and not disconfirm the authors’ paper. Bottom line: Black children have gained 5-6 IQ’s over Whites in the Black-White gap over a 30 yr period. The 15 pt Black White IQ gap is neither fact nor immutable. Nevertheless, by adulthood, Blacks have lost all of their gains and have reverted to the 15 pt gap again. Black adults are not maintaining the gains that Black children made. There are many reasons why this might be so. Perhaps Black children are being challenged more and this is stimulating their IQ’s. As they leave school, many fall into an anti-intellectual Black culture that derides education and learning. Hence, their IQ drops. But Black children, at least, are closing the gap, and Blacks of all ages are experiencing dramatic IQ gains. For a ferocious look at the angry White nationalist community and its rage towards Blacks and Asians, see this American Renaissance paper. AmRen is, frankly, an openly racist White Nationalist publication, but they are pretty polite about it. Curiously, AmRen is hardly anti-Semitic at all. Perhaps this is due to the influence of White Nationalist Jared Taylor. Taylor takes the perfectly reasonable line that Jews are White. Well, of course they are. What other major race could they possibly fall into? Consider that there are 12 major races: White, Black, Asian, Amerindian, East Indian, Polynesian, Melanesian, Micronesian, Negrito, Hottentot, Pygmy and Aborigine. Now exactly where do we put Jews? They can only go into White. Some White Nationalist Jews show up in the comments now and again, and they are welcomed with open arms. I am not a fan of White Nationalism, but promoting the notion that Jews are White seems reasonable enough. Look for the comments at the end for the ferocity and naked racism mentioned above. The comments of the parole officer (the first comment) commenting about how almost all of his Black criminals scored below 80, however, are most interesting. It underscores what we said on this blog earlier, that those scoring at the lowest end of the IQ chart cause the most problems, including crime, as a group. The superb anthropology blog Dienekes notes that the Black White gap in the US cannot possibly be totally genetic. This is because US Blacks score 50 Hopefully, in this post, and in F & D’s paper and response to R & J linked above, we have demolished the rejoinders of “Uncomfortable Truth” in the comments on Dienekes’ blog. I print them here so you can see what he is complaining about. Evaluate for yourself whether or not we have effectively dealt with his complaints:
Well, the paper that egalitarians are hoping will save them has been thoroughly debunked by now. They cherry picked their data.On the whole, the IQ gap remains and American blacks still find themselves with an average IQ of 90. To claim a 4- to 7-point gain for Blacks, Dickens and Flynn chose three independent tests showing medium gains (the Wechsler, Stanford-Binet, and Armed Forces qualification tests)and relegated to their Appendix B four or more tests showing lesser gains. They excluded the Wonderlic Personnel Test, which they acknowledge showed a gain of only 2.4 points for Blacks between 1970 and 2001. (Dickens and Flynn suggest that more ‘‘high quality’’ Whites than Blacks had taken the test.) They excluded the Kaufman Assessment Battery for Children (K-ABC), which Murray (2005) described as showing a loss of 1 IQ point for Blacks between 1983 and 2004. (Dickens and Flynn say the data contained an inflated standard deviation.) They excluded the very g-loaded Woodcock-Johnson test, which Murray (2005; whom they cite) described as showing the conventional gap of 1.05 standard deviations for the third (2001) standardization sample. (Dickens and Flynn say the Blacks were an unrepresentative “subsubsample.”) They also excluded the Differential Ability Scale, which in Lynn’s (1996) analysis (which they cite) showed a maximum gain of 1.83 IQ points for Blacks between 1972 and 1986. (Dickens and Flynn say the sample lacked “quality.”) To be compelling, however, researchers must take the totality of available evidence into account. A strong adherence to an egalitarian dream made them unwilling to.
See the post above for arguments against Uncomfortable Truth’s comments. The K-ABC test has been rejected by none other than Jensen himself. The Woodcock-Johnson sample has also been rejected by a top expert in the field as unrepresentative of the US population and the subsample used was even less representative. As we can see above, using R & J’s own figures, F & J arrived at a recent IQ of about 90 for 15 yr old Blacks. This alone should effectively deal with Uncomfortable Truth’s argument above. The always interesting but frustrating and frankly somewhat racist and sexist Steve Sailer agrees with this post that Blacks have gained 5-6 IQ points on Whites, but also backs up my notion that as Blacks age, they are not being challenged enough intellectually. He blames rap culture. I’ll stay quiet on that one. Steve is a good writer and I read his site often; many times, he makes some excellent points. But he makes his biases quite clear – he feels that males are superior to females and that Whites are superior to Blacks, Hispanics, American Indians, etc. And he is, sadly, quite happy to report studies which back up these notions, while I feel pained, as it is the last thing in the world that I want to believe.
