In one there is a strong history of dementia, in another there seems to be a gene that makes them unusually tall and stupid, and in the other there's a combination of bad genetic and environmental influences. Families like these must have some kind of impact on the overall picture.

This may hold in some current societies. (Possibly more for generation time than number of children per se). I did not discuss it because the original article's claims relate to changes in selection pressures across evolutionary time (or at least thousands of years), rather than differences across social strata in current societies. <br />Kevin Mitchellhttps://www.blogger.com/profile/07172255754953214162noreply@blogger.comtag:blogger.com,1999:blog-6146376483374589779.post-18422412133150964782012-12-18T14:06:30.145-08:002012-12-18T14:06:30.145-08:00Interesting article.

Your assumption is that reproduction rates are otherwise independent of intelligence. In fact, most studies seem to show a negative correlation between fecundity and IQ: http://en.wikipedia.org/wiki/Fertility_and_intelligence#Later_research. Probably is a small effect, could be confounded by SES/transgenerational epigenetic inheritance, and likely won't matter as long as education and environmental stimulation continue to improve. Plus AI. But still, worth pointing out. Andy McKenziehttps://www.blogger.com/profile/07314450642021911177noreply@blogger.com
