Mike thinks we need more threads and less shoutboxing.
Mike and Thomas were discussing the transformation of the marriage institution in Anglo-American society and Mike offered a version of the Devlin/Roissy explanation of female sexual behavior: unrestrained female sexual selection is hypergamous, repeatedly selecting for mates that exhibit signals of strength and status as they existed 50,000 years ago according to a three-year temporal rhythm (by Devlin's study of modern female adulterous behavior.)
The accompanying theory of decivilization, advanced by both Devlin and Roissy, maintains that female sexual behavior tends to select for more present-oriented, low-IQ mates because the 50,000-year-old signals mentioned above tend to cluster among lower-class males. The reproductive consequences, according to Devlin and Roissy, will reduce civilization to the level of the primitive matriarchal sexual economy of sub-Saharan Africa where females entertain a constant stream of alpha males who provide almost nothing for the females or resulting offspring.
Assuming that something like this is true, we would expect to see the suppression of female sexual selection to the benefit of a broad spectrum of male types in more civilized cultures. For example, in Henri de Bracton's medieval treatise on the common law, female sexual selection is subject to the sanction of parents and ultimately the chief lord while male sexual selection is not . The reason for this was primarily the fact that women carried inheritances and the common law marriage rules effectively dissolved a bride's legal personhood and transferred all of her property to the husband. Accordingly, the living owners of the property to be inherited would prefer to exercise control over its distribution and not allow it to be transferred to the first PUA to seduce the female issue.
Although these rules were not motivated by broad, civilization-building concerns, the economic motivation behind them ultimately served as a eugenic protection of the woman's biological inheritance.
