Democratic survival depends on social norms that enforce democratic behavior and punish behavior associated with authoritarianism. Who enforces these norms? Based on social psychological literature, I argue that in post-authoritarian democracies, these norms are enforced by individuals who have a stronger personal experience of authoritarian repression. I test this expectation with newly collected archival data from individuals repressed by the Francoist dictatorship, in Spain. In this presentation, I will discuss a research design for an experiment testing the individual-level mechanism. Because I know the surnames of individuals who were repressed, I can leverage that information as a treatment to update individuals’ perception that their family members may have been repressed. I expect upward updates to increase the probability of enforcement of pro-democracy norms.
