> claims to have a proof for an upper limit in how much "general intelligence" (that would be IQ) can change in the case of individuals or in the case of populations. In fact, the existing OBSERVED degree of IQ increases all around the world I did not mention the Intelligence Quotient (which is subject to boosting). I mentioned the general intelligence factor (which is mostly innate). Using google scholar you can find many interesting articles about the general intelligence factor and its neurological basis. Using google scholar with “general intelligence factor” I found this article that is cited 417 (it just struck my eye since the citations is extremely high for such a recent paper): A Neural Basis for General Intelligence Science 21 July 2000: Vol. 289. no. 5478, pp. 457 - 460 DOI: 10.1126/science.289.5478.457 This one just struck my eye, but there are many more. In my opinion general intelligence factor has become beyond doubt – the question is now what the neurological basis for intelligence is. I also think that we will not do this complex and interesting topic justice if we discuss it here.

The cited article (thanks for the citation to that year 2000 article, which I wouldn't call "recent" on this subject) doesn't address the point I asked you about. There isn't any proof whatsoever that current human beings are fixed in "general intelligence" as soon as their genome is fixed. Rather, there is entire agreement among all researchers that each human being's neurological characteristics are shaped both by genome and by experience--on this point no informed person has any doubt. I also think that we will not do this complex and interesting topic justice if we discuss it here. You are welcome to speak for yourself on that issue, of course. But on my part, I have observed that there are some HN readers who do their homework on genetic and environmental influences on human intelligence before expressing opinions on those issues, and I have learned from some of those participants and so could anyone else who cares to read their comments. I did not mention the Intelligence Quotient (which is subject to boosting). I mentioned the general intelligence factor (which is mostly innate). It is for you to show that there is any practical way to make this distinction, because general intelligence is investigated in human subjects with IQ tests as the main instrument. See any of Ian Deary's extensive writings on this subject for how difficult it is to identify "general intelligence" without looking at IQ.

  > The cited article (thanks for the citation to that year 2000 article, which I wouldn't call "recent" on this subject) The two books you’ve cited are older than this. An article with such a high citation count is usually an old seminal work (citations increase with the age of an article). For an article to have such a high number of citations in only 8 years is somewhat unusual (even when it is a Science paper). > You are welcome to speak for yourself on that issue, of course.

Not really. Raven’s progressive matrices (RPM) are popular. Another method is a barrage of different intelligence tests (the more the better).
