Societies without children, on the other hand, tend to terminate within a single generation.
Since we know intelligence is heritable, it has long been obvious that educating women to the point that they decline to breed was bound to have long-term implications, especially if the women least likely to have children tended to be the most intelligent women. The hypergamous nature of women being what it is, it logically follows that unless the most intelligent women can be supplied with a selection of prospective mates who are more intelligent and more educated than they are, they will increasingly refuse to breed. This has observably been the case, and now the negative effect of encouraging equality in education has been quantified:
This study estimates the effect of dysgenic trends in Taiwan by exploring the relationships among intelligence, education and fertility. Based on a representative adult sample, education and intelligence were negatively correlated with the number of children born. These correlations were stronger for females. The decline of genotypic intelligence was estimated as 0.82 to 1.33 IQ points per generation for the Taiwanese population.What feminists consider progress is literal intellectual regression. Feminism is not only the most evil and incoherent ideology in human history, its natural consequence is the literal enstupidification of any society that permits it to take root.
The connection between the theory of Game and the continuation of civilization should now be readily apparent to even the most dubious skeptic. There is no conceptual model that better describes and predicts what has been observed taking place over the last fifty years in the West.
