LEVYNA conducted field research in Mauritius
In an experimental study published in the European Journal of Social Psychology, Radim Chvaja, Martin Lang and colleagues show that religious *costly* signals are more effective in communicating trustworthiness to religious/secular receivers than secular signals.
Previous research shows that costly religious signals increase trust and cooperation. However, the authors were the first to experimentally test the difference in these effects between religious and costly signals. To do so, they conducted a series of five studies using the pilgrimage to Santiago de Compostela as a costly display of commitment. They discovered that pilgrims base their pilgrim identity on physical effort and that (long-distance) pilgrims/hikers are perceived as more trustworthy, especially so in a religious context.

In a new study published in Human Nature, LEVYNA was part of a team lead by A.K. Willard, studying how witchcraft beliefs affect social norms and behaviors. 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.
