Field Before After
Paper Abstract Can shared social identities help to break echo chambers? We investigate this question through a field experiment with 4,620 unique Twitter users conducted over six months during the 2022 Brazilian elections. Although both political congruence (supporting the same candidate) and social non-political congruence (rooting for the same football team) increase follows and reduce blocks, the positive effect of shared social identity weakens substantially when political identity information becomes available. The effect of political congruence remains strong even after the election and is unaffected by the Brazilian national team's positive results during the 2022 FIFA World Cup, despite the team being a quintessential national symbol. Text analysis of live-streamed tweets of Brazilian nationals during the tournament suggests that this shared national experience failed to reduce political polarization in our setting because polarization had extended to the players themselves. Overall, our results indicate that political polarization can undermine the potential of other shared identities to reduce political divides and foster social cohesion.
