Correcting Misperceptions about Support for Social Distancing to Combat COVID-19
研究纠正人们对社交距离支持度的误解是否会影响实际行为，发现平均效果接近零，但在病例少时减少社交距离，病例多时增加社交距离。
the perceived benefits from social distancing. We estimate impacts on social distancing, measured using a combination of self-reports and reports of others. While experts surveyed in advance expected the treatment to increase social distancing, we find that its average effect is close to zero and significantly lower than expert predictions. However, the treatment's effect is heterogeneous, as predicted by theory: it decreases social distancing where current COVID-19 cases are low (where free-riding dominates), but increases it where cases are high (where the perceived-infectiousness effect dominates). These findings highlight that correcting misperceptions may have heterogeneous effects depending on disease prevalence.
