This chapter approaches the institutional role of the media as a facilitator of trust relationships. Political journalism and the news media function as the principal mediator of trust relationships in democracy. More specifically, the mass media provide information that is relevant for (a) assessing critically the trustworthiness of political representatives in light of their outputs and performances, and (b) engaging citizens themselves in trust-building activities among each other and vis-à-vis government. As a mediator of trust relationships in democracy, political journalism and the news media need however to be trusted themselves and their products in the form of political news need to be found trustworthy. The chapter therefore introduces a distinction between (1) trust in the media, and the way media actors, organisations, content and opinion are found trustworthy, and (2) trust-building through the media and the effects of media content and debates on political trust (and democratic legitimacy).
