Using the case of the Scientific Advisory Group for Emergencies in the United Kingdom as illustration, this essay offers a framework for understanding the role of narratives and competition among narratives in mediating the relationships between scientific advisers and policymakers during the COVID-19 pandemic. Throughout the pandemic, competing judgments about scientific independence and democratic accountability, about the risks of action and inaction, and about the appropriate balance of costs and benefits to society as a whole and to subgroups of the population were filtered through the narrative perspectives of different discourse coalitions. This narrativization of the process had both positive and negative effects. On the one hand, it provided common platforms for the integration of disparate types of knowledge relevant to policymaking. On the other hand, narratives provided platforms for rival coalitions in ongoing contests that left unresolved the central normative questions of distributional fairness and democratic accountability.
