Protest Ongoing

Previous research on protest frequently focuses on societal impacts — how protests influence elites and policymaking — but much less is known about how protests affect bystanders in exposed communities. Our research focuses exactly on these bystanders: how they perceive protest and how direct exposure in local communities matters.

Approach

• Field experiment: Large-scale randomized field experiment randomly routing pedestrians past or away from demonstrations in Berlin, measuring changes in perceptions, social-norm beliefs, and behavioral intentions.
• Fine-grained local data analysis: Street-level data on PEGIDA rallies (2014–2018) and difference-in-differences and matching methods to estimate impacts on local electoral outcomes and immigration attitudes.
• Vignette survey experiment: Comparing reactions to identical protest tactics by farmers versus climate activists to uncover democratic hypocrisy.

Key Findings

1. Bystander behavior: Witnessing protests increases bystanders' alignment with protest demands in their actions, even though underlying attitudes remain largely unchanged.
2. Electoral spillover: Exposure to PEGIDA rallies leads to significant increases in radical-right vote shares and support for stricter migration controls among mainstream right-leaning voters, while left-leaning voters exhibit a backlash.
3. Heterogeneous responses: Effects vary across social identities and prior political orientations — protest exposure can mobilize sympathizers and provoke counter-mobilization among opponents.
4. Selective tolerance: Citizens are significantly more willing to endorse undemocratic responses when protests involve climate activists versus farmers engaging in identical tactics.
