Megastudy Identifying Successful Interventions to Strengthen Americans’ Democratic Attitudes

Deep partisan conflict in the mass public threatens the stability of American democracy. We conducted a megastudy on a national sample of American partisans (n = 32,059) testing 25 interventions designed to reduce anti-democratic attitudes and partisan animosity.  Our findings provide a toolkit of promising interventions for practitioners, and shed new theoretical light on challenges facing American democracy.
