Abstract

Can communicative interventions by the government influence political trust and increase public compliance during crises? This study examines the impact of a televised speech by German Chancellor Angela Merkel at the onset of the COVID-19 pandemic. Using an unexpected-events-during-survey-design, we find that the speech led to a 7-percentage point increase in trust in the federal government and up to a 25-percentage point decrease in citizens' mobility. We also observe demographic variation in susceptibility to speech. We explore the underlying mechanisms by comparing Merkel's speech with similar televised addresses by Mark Rutte and Boris Johnson, where we observe no comparable effects on attitudes. We suggest that specific content, such as an emphasis on solidarity and positive sentiment, may have played a role in mobilizing public support. Our findings indicate that effective leader communication can be a powerful tool for sustaining public support and ensuring compliance with crisis measures.
