Modest affective depolarization gains fail to shift downstream attitudes and behaviors.

Evidence

These findings suggest a significant challenge for the field. Our analysis indicates that the modest changes in out-party affect produced by common interventions may not be sufficient on their own to translate into meaningful changes in downstream social or political outcomes. This highlights the need for future research to develop interventions that can produce more robust effects on a broader suite of attitudes and behaviors. — Derek E.

Categorization

• ADDENDUM: Directly supports my article hypothesis that de-coercion/dialogue interventions produce small, decaying effects — evidence that even at their best (~5 pts) they don’t translate to real behavioral change, pushing toward elite/structural fixes.
