--- - |2 Conversing with diverse points of view stands as the central tenet of deliberative democracy, yet empirical evidence has suggested mixed outcomes related to perspective change as a result of deliberative encounters. I propose a difference‐driven model that suggests individual predispositions moderate the processing of dissimilar views when changing policy preferences. My analysis is based on a random sample of over 400 voters at a California‐wide deliberative event, where participants discussed proposals for reforming the state politics. I find that encountering more and different arguments transforms policy attitudes. Yet it is more difficult for people to change their minds on issues about which they hold strong beliefs. Some evidence suggests that different psychologies are at play for people who enter deliberation with substantial or weak political knowledge and for those who deliberate while holding strong or moderate prior opinions. Well‐grounded strong opinions are resistant to change, while well‐grounded moderate opinions are persuadable in deliberative groups. Uninformed positions can become entrenched in like‐minded groups, yet they can be adjusted once participants deliberate with dissimilar views, especially opinions that are held strongly without good informational ground. The findings urge deliberative forums that introduce participants to diverse perspectives to foster a considered public opinion. - Political Psychology, EarlyView.
