The point is that you can improve IQ scores a lot by education, some of which helps you do better on IQ tests. Whether it is by practicing IQ tests specifically is not relevant.

  I'm no fan of educating people simply to score higher IQs. But the effect of education could be very large: e.g., give an illiterate person an IQ test, educate them and repeat. The change will be ~100 points. To be correct you can improve IQ up to a point (depending on the individual) with education.

    No. It can't be 100. IQ tests don't require literacy. They don't even require language. You could administer IQ test to analphabet who doesn't speak you language and if he cooperates he could get result faily close to their best capacity that could be achieved.

  15 points over two decades is an entire standard deviation improvement for the whole population. One-on-one tutoring has been shown to make a two standard deviation difference. That's the difference between median intelligence and genius. If that isn't large, what is? https://en.wikipedia.org/wiki/Bloom%27s_2_sigma_problem https://en.wikipedia.org/wiki/Bloom%27s_2_sigma_problem Your study is about the effect of an extra year of badly done education on people who drop out of school, which is worth 1 IQ point. That same study shows that the value of mediocre education on people who don't drop out of school is 5 IQ points.

    That improvement might come from all sources. Health and nutrition improvements can have very high impact. Deworming, using safer water. Contribution of education to this 15 points might be just few points. > https://en.wikipedia.org/wiki/Bloom%27s_2_sigma_problem https://en.wikipedia.org/wiki/Bloom%27s_2_sigma_problem It's not about IQ, also, was it ever replicated?

      > Contribution of education to this 15 points might be just few points. It certainly isn't genetics. You're not going to cause a population-wide one sigma increase within a single generation using any genetic mechanism. > It's not about IQ, also, was it ever replicated? Yes, this has been replicated repeatedly. As far as IQ, if you apply for a private school that uses IQ tests for admission, you will find that all of them explicitly forbid test coaching because it is well known that it works. Even a video will cause large gains. https://www.sciencedirect.com/science/article/abs/pii/S0160289620300519 https://www.sciencedirect.com/science/article/abs/pii/S01602...
