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.
