Does religion promote tolerance or fuel conflict? This article examines how specific religious ideas—universal love versus the notion of one true religion—affect prosocial behavior.
Experimental Context: Conducting field experiments in Ghana and Tanzania with Christians and Muslims.
- Universal Love Idea: Fosters equal treatment across groups.
- One True Religion Idea: Increases intergroup discrimination.
These findings offer clear insights into how different religious concepts influence social outcomes—and crucial guidance for policymakers seeking to promote tolerance.
