Right, and without identifying what one means by "formal education" it doesn't provide meaningful data either way.
The other thing that I find curious about this article (that is, the original quoted); there is a globalization of the findings, which clearly are about the Terman cohort.
Can one really generalize to "all children" from a relatively small sample of children with very high IQ?
Or is the author suggesting that both the study cohort AND the controls experienced the effect?
That part is not at all clear.
