Rituals signal mate quality
Peter Maňo, Radek Kundt, and Eva Kundtová Klocová, together with Dimitris Xygalatas, published an article on rituals as signals of mate quality in the journal Current Research in Ecological and Social Psychology.
Advertising cooperativeness
Around the world, people engage in practices that involve self-inflicted pain and apparently wasted resources, such as various religious rituals. Previous research suggests that these practices reliably communicate commitment to group cooperative norms and that benefits from increasing cooperation offset the cost of these practices.
Using a Public Goods Game, the research team shows that cooperative participants are willing to waste part of their monetary endowment to signal their intentions, and as a result, contribute more to a common group pool. By understanding factors affecting the reliability of cooperative communication, this study may help us appreciate the cooperative peculiarity of humankind.
