Depolarization interventions work in lab settings but fall short of reversing societal polarization.

Evidence

Reducing partisan hostility is a desirable goal with the potential to improve societal cohesion and democratic resilience. This paper contributes to this effort by providing a realistic assessment of the magnitude and durability of effects from common interventions. Our findings suggest that while these interventions are often effective in controlled settings, they may have limitations for producing the kind of large-scale, durable change needed to meaningfully reverse societal polarization. This highlights the value of distinguishing between two important research goals: testing the theoretical mechanisms of polarization and developing scalable strategies for societal change. — Derek E.
