Expert knowledge and policymaking: a multi-disciplinary research agenda

The role of experts and expert knowledge in policymaking has attracted growing public and academic attention. Scholarship on the topic has, however, remained deeply fragmented. It is discussed in separate silos of the literature – such as evidence-based policymaking, epistemic communities, and ideas and politics – and this has hindered sustained empirical study. This article argues that to stimulate more systematic research on the role that experts play in policymaking and develop a theoretical understanding of it, we need to foster dialogue across these literatures. To facilitate this, the article critically reviews how the role of expert knowledge in policymaking is conceptualised and explained in existing literatures, and offers suggestions about how to create common ground for future research by reframing research around the question of the influence of experts, and examining more closely the administrative underpinnings of expert influence.
