This article considers the normative and critical value of popular comedy. I begin by assembling and evaluating a range of political theory literature on comedy. I argue that popular comedy can be conducive to both critical and transformative democratic effects, but that these effects are contingent on the way comedic performances are received by audiences. I illustrate this by means of a case study of a comedic climate change ‘debate’ from the television show, Last Week Tonight. Drawing from recent scholarship (...) on deliberation, judgment and rhetoric, I highlight both critical and transformative dimensions of the performance. I attribute these to the vignette’s likely reception, which I describe as ‘dissonant’ – unresolved, affectively turbulent and aesthetically attuned. I argue that comedy is uniquely positioned to spur such ‘dissonant’ modes of engagement and, in so doing, to promote acknowledgement and reflective judgment. (shrink)
