Practice with the test improves scores, but only to a point
Working on brain improving activities, especially age 0-3, and 3-25, but somewhat at any point will make your brain work better
There is a huge genetic component to people’s maximum possible score, after 1 & 2, as well as their baseline score before 1 & 2, and how well #2 works.
Sadly, I can only share the synthesized results of years of reading—I don’t keep track of where my ideas come from (though I do try to avoid known-bad sources)
#1 is seen with SAT scores—taking the test a second time / taking a prep course improves the median student’s score by ~10 percentage points. I (and others) attribute this to improvements in the “IQ test taking ability” portion of the SAT, not the “have memorized vocabulary and rules of math” portion.
#3 is clearly seen in results from twin studies, adoption studies, and just looking at the world (ie we see a wider range in “ability to do things we would predict high IQ people to be better at” among people with similar childhoods than we do among people with dis-similar childhoods in extended families.
Just stick “heritability of intelligence” in scholar.google.com. I have only had experience of intelligence tests on 4-6 six year olds. Quite a few dimensions to the test—but nothing that would have been practiced at home. A very limited sample, but the resultant ranking fitted my pre-determinations in terms of general problem solving abilities.
There are three components:

Interesting, can you direct me to some scientific papers which prove conclusions (1) and (3)?
(I already believe (2))
