You shouldn't invoke Turkheimer's three laws paper (which is a good paper) to make a statement with which Turkheimer would disagree. Turkheimer certainly agrees with the factual observation that formal education (which is part of the environment not necessarily shared by siblings in the same family) can raise IQ. You can look up a paper on which he is a co-author for more details. (I correspond with Turkheimer from time to time, and know many of his co-authors and colleagues.)

The link to the paper here is from Eric Turkheimer's faculty webpage at the University of Virginia, which I visit often to read his latest publications.

Turkheimer's laws are not the property of the man himself! I think it's pretty safe to say there's no clear winner on what the effects of schooling is on the margin at least.

You're right to correct me on school being part of the nonshared environment that's my mistake, you probably know more than me how complicated it is to extract meaning from the nonshared environment. Also the temporary nature of the improvements are very confusing. Thanks for the paper.
