Given that the number of children one has is inversely correlated with 'intelligence'

This is very likely untrue, according to thorough statisticians and professional geneticists.

If you have a citation for professionally published research on the point I would be happy to look it up. More good information about the subject can be found at

for readers who would like to look up the facts.

I asked my wife of twenty-six years, the mother of our four children, what she thought of this link, and she commented that maybe the link just shows that IQ and intelligence are not quite the same thing. It is paradoxical to suppose that high intelligence people might have less reproductive success than average intelligence people, but it's not too far of a stretch to suppose that IQ tests fail to capture all of the intelligent behavior necessary to enjoy reproductive success.

An older but much more thorough source on some of the same issues is

with some very good discussions of differential rates of reproduction by IQ score.
