Great discussion. Worrying implications for western society though.

If Caplan is right, and the data says he is, the declining birth rate among the wests richest and smartest is a death knell.

Also, it would suggest we radically re-evaluate the usefulness of almost all redistribution programs. If outcomes are almost entirely genetic, we get far more efficient results by getting the rich/smart to have more kids than by trying to uplift the downtrodden.
