The fact there is a growing backlash to immigration in communities around the world is well established. What is less discussed are the solutions to address decline in social cohesion and rise in mistrust, misinformation, and prejudice. Meaningful contact between different groups can reduce tensions. Under the right conditions, this dynamic can strengthen social cohesion when newcomers and members of established communities come together and build meaningful relationships. Linda R. Tropp, a professor at the University of Massachusetts Amherst, has spent decades studying how members of diverse groups experience contact with each other. In this episode, she and Natalia Banulescu-Bogdan, Deputy Director of MPI’s International Program, discuss contact theory and the triggers that can make such relationships succeed or fail.
