Learning by Laughing: Humour as Moral Error Detection and the Ethics of Immoral Jokes

Abstract Philosophers tend to treat immoral jokes as best avoided, if not outright condemned. This essay challenges that consensus. I argue that many immoral jokes, far from undermining moral life, can enhance it. If moral features influence a joke’s funniness—as comic moralists and immoralists both claim—then humour can track our deepest norms, helping us perceive moral incongruity. That is the basis for what I call the humour-as-moral-error-detection thesis (HMED). Troubling jokes do not just risk harm. They can also crack open reflection, rattle certainties, and cultivate the very moral growth that critics of offensive humour aim to preserve. Joking’s distinctive features, such as its non-literality and play, make it especially well-suited to this task. Rather than viewing immoral jokes solely as threats to be policed, I propose a permissive ethical stance: one that treats immoral humour as a site of moral-epistemic possibility, and invites audiences to engage rather than retreat.
