Durable depolarization requires structural or institutional rather than one-shot interventions

Evidence

As one prominent paper notes, “durable effects likely require structural and/or institutional interventions that repeatedly and/or more strongly implement the general strategies identified in this work” (12). — Derek E. Holliday, Yphtach Lelkes, and Sean J. Westwood, Why Depolarization Is Hard, 50
