Abstract Extensive research has examined whether political satire promotes or suppresses political discussion, but far less attention has been paid to how it shapes discourse quality. This study investigates the impact of political satire on discourse quality by scrutinizing the substance of online discussions in a non-democratic context. Drawing on manual content analysis of discussions on a major Chinese social media platform surrounding China’s controversial policy to raise the age of retirement, we analysed original posts and subsequent replies (N = 3,400) to assess the impact of satire on online political talk. The results show that political satire significantly decreases topic relevance and rationality, while exerting no significant effect on civility, and virtually precludes argument reciprocity. These findings contribute theoretically by shifting the focus from whether satire stimulates political engagement to how it influences the substantive quality of deliberation. They also invite a reassessment of the often-overemphasized optimistic role of political satire, highlighting its potential to erode rational and constructive discourse.
