"Partisan media are often blamed for polarization in newly liberalized regimes. However, there is little empirical work on the subject, and information-processing theories suggest that extreme position taking is only one possible response to opinionated news. Rather, we theorize that partisan media

may cause moderation in postliberalization settings, because low political sophistication and shifting political landscapes discourage partisan-motivated reasoning. We conducted a field experiment in Ghana in which tro-tros (commuter minibuses) were randomly assigned to one of four conditions. Passengers heard live talk-radio from a progovernment, pro-opposition, or neutral station, or were in a no-radio control. We find no effect of like-minded media on polarization, but significant evidence of moderation from cross-cutting broadcasts, indicating that rival arguments persuaded subjects. Partisan broadcasts also encouraged displays of national over partisan identity. Rather than fueling extremism, we argue that partisan media can moderate by exposing citizens to alternate perspectives." (Abstract)

"This paper focuses attention on randomised field experiments in the developing world that explicitly address the use of media to achieve democracy and governance (DG) outcomes [...] The first section describes the growth of DG assistance and the increasing interest in DG field experiments. The seco

nd section describes the domain of media assistance targeted at DG outcomes. The third provides an overview of current experimental and quasi-experimental studies on the intersection between media, democracy and governance. The fourth and fifth sections describe some of the challenges to successfully employing field experiments to inform media assistance programmes. The final section concludes by arguing for the benefits of practitioner-academic collaborations that provide experimental evidence about the influences on as well as the effects of media content related to democracy and governance."
