Making pandemics big: On the situational performance of Covid-19 mathematical models

Abstract: In this paper, we trace how mathematical models are made ‘evidence enough’ and ‘useful for policy’. Working with the interview accounts of mathematical modellers and other scientists engaged in the UK Covid-19 response, we focus on two weeks in March 2020 prior to the announcement of an unprecedented national lockdown. A key thread in our analysis is how pandemics are made 'big'. We follow the work of one particular device, that of modelled ‘doubling-time’. By following how modelled doubling-time entangles in its assemblage of evidence-making, we draw attention to multiple actors, including beyond models and metrics, which affect how evidence is performed in relation to the scale of epidemic and its policy response. We draw attention to: policy; Government scientific advice infrastructure; time; uncertainty; and leaps of faith. The ‘bigness’ of the pandemic, and its evidencing, is situated in social and affective practices, in which uncertainty and dis-ease are inseparable from calculus. This materialises modelling in policy as an ‘uncomfortable science’. We argue that situational fit in-the-moment is at least as important as empirical fit when attending to what models perform in policy.
