This chapter addresses how research and public debate about migration interact with and inform each other, focusing on public perceptions and media coverage as important aspects. Factors including generalized public innumeracy about migration levels, effects of emotions on perceptions, and variation in the perceived credibility of different messengers make communicating information—of which research evidence is an important type—a complex process with multiple points of potential resistance. Meanwhile, the demands and expectations of public users and policy-makers can influence how research happens and the types of questions that are seen to be more meaningful. These interrelationships exist within wider social, political, and economic contexts that, in certain circumstances, are likely to favour some outcomes over others. In total, the chapter argues that the pathway from generating research evidence to impacting public debates is not only uncertain, it is also more complex than is often presumed.
