A little more than a year ago, a coalition of multidisciplinary researchers at Stanford, MIT, Northwestern, the University of Pennsylvania and Columbia set out to crowd source ideas to address the political divide in what was dubbed the Strengthening Democracy Challenge. “Anti-democratic attitudes and support for political violence are at alarming levels in the US," said Robb Willer, Director of the Polarization and Social Change Lab and Professor of Sociology at Stanford, at the time of the announcement. "We view this project as a chance to identify efficacious interventions, and also to deepen our understanding of the forces shaping these political sentiments.”

After reviewing more than 250 submissions from researchers, activists and others, the research coalition selected 25 interventions it deemed most promising to test against one another in an "experimental tournament" utilizing a sample of 31,000 U.S. adults. To learn more about the challenge, some of the promising projects that emerged from it, and whether tech platforms may play a role in efforts to address polarization, I spoke to Willer and his colleague, Jan Gerrit Voelkel, a Ph.D. student in the Department of Sociology at Stanford University and also a member of the Polarization and Social Change Lab.
