What leads people to contribute to public life, to strengthen social cohesion, and work to better society? We investigated how co-curricular aspects of college life relate to social cognitive processes foundational for civic virtues and contribute to their development. We examined one widespread type of co-curricular college experience--studying abroad. When studying abroad, students encounter different social norms and cultures and often interact with others using a non-native language. How does immersion in an unfamiliar society affect psychological capacities, such as epistemic humility and regard for others, that may be central to civic virtues? We compared measures of civic virtues across students who studied abroad, students interested in studying abroad who had not yet had that experience, and students with no interest in studying abroad to understand how differences in civic engagement and civility relate to aspects of students' psychology such as epistemic humility, empathy, and need for cognition.
