Deliberation depolarizes only when structured by deliberative-democracy design features, otherwise discussion polarizes.

Evidence

First, and in line with the contradictory findings of previous studies, we argue that group discussions do not consistently reduce polarization. Rather, we argue that the effects of communicative encounters on polarization are conditional on how those types of communication were conceptualized across disciplines. More precisely, we generally find depolarizing effects when group discussions adhere to a deliberative democracy framework, and more frequent polarization effects when they do not. … In particular, design factors that are often implemented in deliberative democracy studies, such as group composition, facilitation, and interaction mode, are positively associated with depolarization. In other words, deliberation seen as a form of organized group decision-making with specific design features as advocated in the field of deliberative democracy, does indeed decrease polarization; but other forms of group discussion with less stringent design factors increase polarization. — Didier Caluwaerts et al., Deliberation and Polarization, 18
