How do people decide whether specific minority behaviours should or should not be tolerated in society? The current research investigates the role of moralization in tolerance of Muslim minority behaviours that differ in their level of perceived normative dissent with four national samples of majority group members in the Netherlands and Germany ( N = 3628). Study 1 revealed that behaviours perceived as more normatively dissenting were increasingly moralized and tolerated less. In Studies 2 and 3, we found that more normatively dissenting behaviours prompted people to prioritize the moral value of social cohesion over freedom and become less tolerant. Finally, Study 4 shows that priming the moral value of religious freedom decreases intolerance of a highly dissenting Muslim minority practice. Taken together, these studies reveal that moralization and value prioritizing can be associated with either intolerance or tolerance of minority behaviours depending on the perceived normative dissenting nature of these behaviours.
