In an earlier post, I discuss Finkel and Eastwick's fascinating finding that, under some circumstances, women can be just as indiscriminate in mate choice as men are, and, in the followup post, suggest one possible evolutionary psychological explanation for it by my colleague. Now a very insightful reader offers another possible explanation.

Just to recap, Finkel and Eastwick's experiment using the speed-dating format showed that, when men rotate among women, women were much more selective in mate choice than men (as one would expect), but when women rotate among men, they were just as indiscriminate and aggressive in mate choice as men were. Since sex differences in mate selectivity is a deeply ingrained part of male and female evolved human nature, it doesn't make sense that the typical pattern can be so easily reversed by a temporary change in the institutional arrangement of who approaches whom.

My friend and colleague, Diane J. Reyniers, then offered one possible explanation based on the Savanna Principle about the evolutionary limitations of the human b
