Interventions effective in controlled settings may fail to produce large-scale durable polarization change.

Evidence

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. Holliday, Yphtach Lelkes, and Sean J. Westwood, Why Depolarization Is Hard, 73
