Witchcraft, Envy, and Norm Enforcement in Mauritius

Specifically, researchers investigated whether witchcraft is regarded to be motivated by envy and how this notion influences community interactions. 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. Maňo looked at variation in motivations for ritual practice and how it relates to the socioeconomic status of respondents. 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.
