As we know from natural experiment of Dutch famine of 1944 mother’s health is extremely important. This brief event had significant effects on two generations.
I get the impression that multi-generational effects don’t get into the popular press much. I’m guessing that people don’t want to think about problems which would take a long time to get better.
Do you know whether two generations was enough to undo all the effects of the famine?
Why’s that relevant, when the question is what parents can change by how they treat their children? (It would be highly relevant if the question were “how much of these differences are genetic?”, but on this occasion it isn’t.)
Also, twins share their uterine environment.
This wouldn’t apply to IVF twins reared apart, but I doubt there’s much of that in the studies.

I’m addressing the piece taw linked to, which was about flaws in studies of twins separated at birth.
Some degree of topic drift is normal here. Have you been in venues where all comments are supposed to address the original topic?
No, I have no problem at all with topic drift. It just wasn’t clear to me that that was what had happened. My apologies for any unnecessary confusion.
Caplan’s arguments are totally wrong, it doesn’t make his thesis wrong. I’d expect his thesis to be very likely to be at least mostly correct.
