ABSTRACT Conspiracy culture cultivates suspicion towards the hidden workings of power. While some modes of suspicion direct critical attention towards the crimes and cruelties of oppressive social relations, other modes misdirect that same attention. When such misdirection serves to reproduce oppressive social relations, entrapping its adherents in the promise of emancipation, this may be understood as ‘repressive suspicion’. Empirically, this concept is characterized, herein, via a reception study of the QAnon conspiracy theory, reconstructing how one of the most prominent participants in the insurrection in Washington, D.C., on 6th January 2021 became wrapped up in ‘Q’ culture – a story that paints a poignant, complex picture of repressive suspicion. This concept is then further developed in historical and theoretical terms, in dialogue with the works of Herbert Marcuse, leading to an analysis of QAnon as a microcosm of the contemporary crisis of hegemony, drawing on Antonio Gramsci, Stuart Hall, and Nancy Fraser. While, in the 1960s, and even in the 1990s, repressive suspicion could be largely ignored by practitioners of political critique, in the current conjuncture this is no longer the case. Thus, as well as constructing a diagnosis, this article also poses a question: If this is what repressive suspicion looks like, how must we conceive its opposite?
