Fertility and intelligence may be correlated, but that does not state much about intelligence and birth rate. Just because two -things are correlated, does not imply causation, and even if they are, their may be non-listed effects which cause results opposite those that would be anticipated with only two factors taken into consideration.
Gah. Classical evolution is over. To clarify: Evolution is real, but it is also glacially slow. Social changes are orders of magnitude faster, and technology faster still.
The odds of selective effects causing any changes whatsoever to human nature before someone rewrites our genome like it is a manuscript in dire need of editing are zero. The time scales are wrong. As far as evolution is concerned, if it takes us 300 years to master genetic engineering, and another 500 before the laws against it stop being enforced, then that is a bullet Darwin cannot dodge. And after that point, evolution is no longer blind.
Fertility and intelligence are negatively correlated.
Religiosity and intelligence seem to be negatively correlated.
Therefore all the efforts of Dawkins, Yudkowsky etc. to make the world more rational seem to be futile or at least inefficient. Pretty scary...
