I read something relating. I read that during WW1 the army tested every recruit for IQ levels. Jewish people tested 10 points below the average. Then, in WW2 the army had another huge group of people and tested them again. Jewish people tested 10 points above the average. So, this raises the possibility that an entire group raised its' IQ.
I agree with Sowell in the article when he said that cultural pathologies are causing IQ problems for some groups. I also think public schools and bad tv habits are causing low IQ's for many people. You must read what smart well trained minds wrote and let your own mind be trained by them in order to develop a high IQ.

There is something called the "Flynn effect" that has been confirmed by numerous studies. Usually there is a pattern of an average increase of over three IQ points per decade. This is found in virtually every type of intelligence test, delivered to virtually every type of group. The increase was highest, 20 points per generation (30 years), in Belgium, Holland and Israel, and lowest, 10 points per generation, in Denmark and Sweden. Although the data are limited, it moreover seems that the increase is accelerating. In Holland, for example, scores went up most (over 8 points) for the last measured period, 1972 to 1982. For one type of test, Raven's Progressive Matrices, Flynn found data that spanned a complete century. He concluded that someone who scored among the best 10% a hundred years ago, would nowadays be categorized among the 5% weakest. Essentially, this is why IQ tests must be re-standardized.
The explanation for this is unclear. At least one item is that nutrition seems to be a crucial variable on the left hand side of the bell curve. Also, there is a suggestion that learning how to deal with timed tests, having taken other tests may play a part as well.
As far as Black/White IQ's see Rushton's Book Review of Jensen's book on the "g" factor. It is found on Stalking the Wild Taboo. The difference has been constant for over 80 years. Controlling for socio-economic background makes at most a four point difference. Both culture fair and non-verbal tests do not improve things. Blacks for 80 years have also consistently scored lower than Native Americans, Mexicans and Asians.
It really is too bad everyone has become upset about this. The real problem is a solution. Jensen found 40 years ago that on rote learning and shor-term memory tests Blacks score very favorably as compared to Whites. So what do liberal educators discourage? You got it --rote memory.
While there are always quarrels as to what an IQ test measures and whether it is valid, remember that we now have evoked potential and other physiological tests that correlat quite well with what is called "g" or general intelligence.

All Army IQ testing can do is measure the IQs of people who decide to show up to go into the Army -- which might not be a representative sample of the population.
