Thanks to the generous support from the Operational Programme “Research, Development and Education”, we have just launched a new project “Scarring Rituals, Fierce Intergroup Conflict, and Extreme Prosociality” (SACRIFICE). Martin Lang will use this opportunity to study the role that extreme rituals play in intergroup conflict.
Under the supervision of David Václavík (Masaryk Uni) and Ben Purzycki (Aarhus Uni), Martin will study how participation in costly rituals affects the willingness to sacrifice one’s resources during inter-group conflict, both in the lab and in Mauritius.
In an incentivized controlled lab experiment published in the Journal of Economic Psychology, Miloš Fišar together with members of LEVYNA and other colleagues show that there are no systematic effects of ovulatory shift on salient behavioral outcomes like risk preferences, rule violation, and exploratory attitude.
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.
