Interesting, but not earth-shattering. Reminded me of studies such as those referenced here (http://freakonomics.com/2011/04/11/economics-and-genetics-of...), finding that "with a few exceptions, adoption and twin researchers find that nature overpowers nurture, especially in the long-run."

Assuming that the "nurture" is roughly comparable. It's a weird paradox that societies put great effort into countering environmental factors make genetics more important.

For an extreme example, if I "nurture" a random selection of people by killing them, then their genetic gifts will not make that much difference to their IQ, GPA or salary, because they will be dead. In a society where they all get to experience 12 years of education and socialized medicine, those random environmental factors will be dampened and genetic factors boosted.
