You are right. And that's at least the second time I've made that mistake, so hopefully I'll learn from it.

Let me ask the sociological question I should have asked: It appears that many of the folks invested enough in "rationality" to be active participants in LW not only don't have children, but think that having children is not a good goal. That constellation of beliefs suggests that there is some selection pressure that links those two beliefs. Should the existence of that selection pressure worry us on "Add up to normal" grounds?
