The effects of government propaganda in electoral authoritarian regimes: Evidence from Turkey

Abstract Previous research conducted in closed autocracies indicates that government propaganda can deter opposition, shift political attitudes, and influence emotions. Yet the specific mechanisms and contextual factors influencing how and when propaganda works remain unclear. We theorize how power-projecting government propaganda works differently for government supporters and opponents in polarized electoral authoritarian regimes, focusing on emotional reactions, sense of societal belonging, and downstream effects on contentious political behavior. Through two preregistered surveys in Turkey ( N = 6,286), we find that supporters exposed to propaganda videos feel a greater sense of belonging and are more susceptible to engage in pro-government activities. Opponents report heightened anger and anxiety and seem deterred from protesting. However, the latter effect weakened during the highly contested 2023 electoral campaign. These results indicate that propaganda can help electoral authoritarian regimes deter anti-government action and encourage pro-government action, but that its deterrent effects may weaken during periods of high mobilization and contention.
