In response to Paniagua and Rayamajhee's (2021) proposal for a polycentric approach for pandemic governance, Frolov (2022) notes that their paper focuses on preventive measures, and neglects the deeper, cognitive dimension of coproduction. In this essay, we extend the notion of coproduction to analyze the cognitive institutions that underlie social behavior during a pandemic. We analyze the role of coproduction and polycentricity in the emergence and persistence of shared mental models, including counterproductive models such as virus skepticism, conspiracy theory beliefs, and antivaccine narratives.
