The messy politics of combating the COVID-19 pandemic, compounded by the confusion caused by the global (dis)infodemic, have propelled conspiracism from the fringes of society into the public mainstream. Despite the growing political impact of digitally enabled conspiracy theories, they are predominantly delegitimized on three fronts – as psychopathology, pseudoscience, and/or parapolitics. In contrast, this article employs three non-pathologizing conceptual counteroffers borrowed from critical theory, deconstructionist historiography, and citizenship studies – namely, cognitive mapping, narrative emplotment, and performative citizenship – to (...) politicize conspiracy theorizing ‘from below’. Using QAnon as a case-in-point, the article introduces two novel concepts that invite a sociological approach to conspiracism: first, the epistemic communities of the unreal, which designates the participatory, interactive, and decentralized nature of collaboratively creating unreal explanations of the real world; and second, grassroots conspiracism, which denotes the ways in which these bottom-up, horizontal, and collective meaning-making practices and knowledge-production processes are expanding spaces of and for politics.
