🌤️So is it all doom and gloom? No! While echo chambers polarize, even a half-an-hour conversation with people from the other party can reduce polarization. Interventions that encourage cross-partisan discussion, however limited, may be key to ameliorating partisan animosity. 7/n

We also show results by partisanship. These reveal that echo chambers only significantly increase affective polarization among Labour partisans. This finding may be explained by incumbency dynamics  6/n

We also find that echo chambers increase policy polarization. Being assigned to discuss in a homogeneous group, compared to a mixed group, entrenches partisans’ policy views. Conservatives become even more in favour of the policy, while Labour partisans become more opposed to it. 5/n

We find that being assigned to discuss in a partisan echo chamber, compared to a mixed group, increases affective polarization by around 5 points, or a quarter of a standard deviation.➡️ Echo chambers polarize! 4/n

We test the effect of echo chambers on polarization using a large-scale pre-registered “lab-in-the-field” experiment in the UK, randomly assigning partisans to discuss a salient policy issue in either a mixed partisan group or a homogeneous group 3/n

Partisan polarization is of increasing concern across the world. What causes polarization? We examine the argument that partisan “echo chambers” – people surrounded by likeminded partisans – fuel polarization  2/n
