Deliberative mini-publics are forums for citizen deliberation composed of randomly selected citizens convened to yield policy recommendations. These forums have proliferated in recent years but there are no generally accepted standards to govern their practice. Should there be? We answer this question by bringing the scholarly literature on citizen deliberation into dialogue with the lived experience of the people who study, design and implement mini-publics. We use Q methodology to locate five distinct perspectives on the integrity of mini-publics, and map the structure of agreement and dispute across them. We find that, across the five viewpoints, there is emerging consensus as well as divergence on integrity issues, with disagreement over what might be gained or lost by adapting common standards of practice, and possible sources of integrity risks. This article provides an empirical foundation for further discussion on integrity standards in the future.
