Making expert advice public in a time of emergency: Independent SAGE and the contestation of science during the Covid pandemic in the UK

This article presents a situational analysis of the expert advice offered by Independent SAGE, a group of scientists that formed in May 2020 in the UK to provide advice on the Covid response. Based on interviews with the group's members and partners, we argue that through its interventions Indie SAGE demonstrated an important alternative approach to linking science and politics in a time of emergency. They showed that the only way to ensure that policy and decision-making on Covid-19 was grounded in knowledge was by making expert advice public. Indie SAGE's decision to 'go public' was a response to the political situation in the UK, one in which scientific advice, in particular public health expertise, was being ignored, sidelined and contested as such. We identify four rationales for making expert advice public: openness, calling out, translation, and responsive engagement. We describe associated modes of intervention that Indie SAGE adopted in relation to different critical situations of Covid-19. Distinctive about their advice, we argue, is its prioritization of <i>situational adequacy</i>. Much of it was explicitly oriented towards addressing practical and existential challenges experienced by particular social groups, professions and everyday publics. We argue that this way of making science public in an 'ontological' register acquires critical importance in a political situation like the UK Covid response, which was marked not just by disagreements about science but growing contestation of science as such. In this respect, our study holds a wider lesson for the understanding of the role of evidence in public politics. To advocate for evidence-based governance, as Indie SAGE did, is not necessarily to endorse a post-political vision of government. When science is contested in a time of emergency, making evidence public becomes a key means for responding to the demands of situations. It is not only pragmatic but a critical accomplishment.
