Deliberation depolarizes groups only when sufficient disagreement is present.

Evidence

In line with Dryzek et al. (2019) argument, data suggest that deliberation among likeminded individuals is more likely to polarize groups (63.6%) than to moderate groups (27.3%) even though the number of studies with exclusively homogeneous groups is low (n = 11). Informational or affective inbreeding is thus reported to push groups to extremes more often than internally diverse groups. After all, heterogeneous groups observe more depolarization effects (54.8%) than polarization effects (26.2%). Based on the analyzed publications, deliberation can thus have depolarization effects, as long as there is sufficient disagreement in the deliberating group. — Didier Caluwaerts et al., Deliberation and Polarization, 117
