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.

The findings show that, while witchcraft accusations were common, they were mostly directed at persons suspected of acting out of envy.

Socioeconomic variation in motivations for ritual practice – a new study by LEVYNA & UConn

In an ethnographic survey-based study published in the journal Religions, D. Xygalatas and P.

The findings indicate that whereas people of lower socioeconomic standing address more immediate concerns related to material security and safety in their ritual practices, people at the other end of the socioeconomic spectrum tend to focus on the fulfillment of spiritual, social, or cultural needs.

Experimentally testing the existential insecurity hypothesis

In a new Registered Report published in Collabra, M. Lang and R. Chvaja experimentally tested whether secular individuals would be willing to join religious groups when threatened with cooperative insecurity. The results showed that while this effect was weak in a behavioral test, a self-reported willingness to join was much stronger than anticipated.
