Many of the approaches to engagement through which researchers seek to consider their work have emerged from democratic framings of participation and such settings are explored within this chapter, as context for researchers keen to use such approaches, along with the citizens’ role in such negotiations. The chapter considers why deliberative approaches might appeal to the research communicator, before discussing in depth public engagement and what this can involve in research communication contexts. The chapter also considers the role of communication and engagement within policymaking processes, and the part which researchers may or may not wish to play in it.
