We investigate how being exposed to media influences levels of anxiety and political attitudes in conflict-affected areas. Exploiting exogenous variation in signal strength of a radio station in South Sudan's Western Equatoria State, we compare original qualitative and quantitative data from areas with differing radio coverage. Civilians living in areas with more exposure to radio are more afraid of attacks by the Lord's Resistance Army (LRA). This anxiety means civilians rely more on a civilian militia, the arrow boys, and less on the state army. Hence media, through fear, can contribute to changing social and political structures. Can the power of media be harnessed to positive effect to improve situations of violent conflict? In conflict situations, media has been considered both as contributing to hatred, most prominently during the Rwandan genocide (Yanagizawa-Drott, 2012), as well as a force for peacebuilding (Paluck and Green, 2009a; Paluck and Green, 2009b; Orme, 2010; BBC Media Action, 2012). Setting up a radio station has become standard UN practice in post-conflict situations (Orme, 2010). However, the role of media in situations of violent conflict or developing countries, be it a positive or a negative one, is under-theorised and empirical evidence is scarce (Paluck and Green, 2009b; Schoemaker and Stremlau, 2014). The same cannot be said of theories and empirical studies on the role of media in developed countries without violent conflict. In these contexts, media is sometimes thought to cultivate fear (Furedi, 1997; Furedi, 2005). Numerous theories describe how media might influence risk estimation, ranging from rational choice models (Fielding and Shortland, 2009) to theories emphasizing 'automatic' and subconscious modes of thinking (Tversky and Kahneman, 1973; Gerbner, Gross, Morgan and Signorielli, 1980). Research on the fear-inducing effect of media goes back more than thirty years (Gerbner et al., 1980) but whether and through what mechanism media contributes to anxiety remains subject of debate and evidence is heavily dominated by studies in developed countries. The potential fear-inducing effect of media is of interest especially in light of a growing literature on the role of emotions in the formation of political attitudes, in
