The Long-Term Impact of Mobilization and Repression on Political Trust

Authoritarian regimes respond to threatening student movements with repression and censorship. In many cases, failed movements are effectively erased from public memory. Do such movements affect long-term attitudes? We use a survey of college graduates to measure the impact of a failed student movement. Some of our respondents began college immediately before a major protest; others started after the movement had been suppressed. Using a fuzzy regression discontinuity, we find that individuals who attended college during the movement are significantly less likely to trust the government, more than twenty-five years later, than individuals who enrolled after the protests. The effects are strongest for trust in the central government, and weakest for local government. These results are robust to a range of specifications, and show that the experience of mass mobilization and state repression can have a long-term impact on public attitudes, even if the event in question remains taboo.
