Much of the evolutionary literature on mate choice presumes that individual mate preferences function to increase individual fitness, and this assumption has been confirmed in several experimental studies with animals. However, human mate choice, in many cultures, is heavily controlled by parents via arranged marriages, rather than the selection of...
Mate preferences probably evolved to increase fitness; however, studies using arranged and non-arranged marriage as proxies for limited and free mate choice (respectively) do not find any reproductive differences. We explore why arranged and non-arranged marriages are an imperfect proxy for limited and free-choice matings and what fitness effects d...
In many species, females and males form long‐term mating bonds, but marriage—and especially arranged marriage—are uniquely human traits. While marriage practices impact many cultural phenomena, they also can have evolutionary (i.e., fitness) consequences. Strongly felt but not necessarily conscious mating preferences presumably evolved because they...

This set of experiments shows that in 15 traditional small-scale societies there is an extraordinarily close correspondence between ( i ) the intensity of shame felt if one exhibited specific acts or traits and ( ii ) the magnitude of devaluation expressed in response to those acts or traits by local audiences, and even foreign audienc...
