Depolarization interventions produce small, decaying effects that fail to scale or shift downstream attitudes

Evidence

Building on this body of work, this article provides a multifaceted evaluation of the challenges involved in scaling depolarization. First, existing interventions typically yield modest effects, which often diminish rapidly over time. Second, the reduction of affective polarization, even if achievable, does not necessarily influence related attitudes of interest (such as support for antidemocratic actions or political violence). Finally, repeated exposure to these interventions or prolonged treatments has not demonstrated cumulative benefits, suggesting that simply increasing the intensity or frequency of such efforts is unlikely to produce meaningful results. — Derek E.
