Distinguishing Active and Passive Outgroup Tolerance: Understanding Its Prevalence and the Role of Moral Concern.

Tolerance, the acceptance of disapproved conduct of others, is considered an indispensable feature of diverse societies. Yet tolerance can be expressed in one of two distinct ways, which is not reflected in the literature. In one way, tolerance is passive and involves suppressing the inclination to interfere with the disapproved conduct of others. In the other way, tolerance is active and involves endorsing the ability of others to engage in a disapproved practice. Using two nationally representative samples of Dutch majority members and eight scenarios involving real-world debates about the accommodation of Muslim minority practices, we find that while a significant minority of people engage in passive tolerance toward disapproved outgroup practices, very few people are willing to engage in active tolerance by proactively supporting disapproved practices. Furthermore, we also find that people who have stronger moral concerns about particular minority practices are less willing to engage in either active or passive tolerance. These results emerged both in contexts where Muslim minority practices had a direct impact on one's personal life as well as those that impacted on society as a whole. Collectively, these results illustrate two different forms of tolerance and the influence of moral concern in tolerance.
