Voluntary physical distancing is essential for preventing the spread of COVID-19. We assessed the role of political partisanship in individuals' compliance with physical distancing recommendations of political leaders using data on mobility from a sample of mobile phones in 3,100 counties in the United States during March 2020, county-level partisan preferences, information about the political affiliation of state governors, and the timing of their communications about COVID-19 prevention. Regression analyses examined how political preferences influenced the association between governors' COVID-19 communications and residents' mobility patterns. Governors' recommendations for residents to stay at home preceded stay-at-home orders and led to a significant reduction in mobility that was comparable to the effect of the orders themselves. Effects were larger in Democratic- than in Republican-leaning counties, a pattern more pronounced under Republican governors. Democratic-leaning counties also responded more strongly to recommendations from Republican than from Democratic governors. Political partisanship influences citizens' decisions to voluntarily engage in physical distancing in response to communications by their governor.
自愿保持身体距离对于防止 COVID-19 的传播至关重要。我们使用了 2020 年 3 月美国 3100 个县的手机移动数据、县一级党派偏好、有关州州长政治归属的信息以及他们关于 COVID-19 预防的交流时间，评估了个人对政治领导人保持身体距离建议的遵守情况与政治党派之间的关系。回归分析研究了政治偏好如何影响州长的 COVID-19 交流与居民的移动模式之间的关系。州长建议居民待在家里，这先于居家令，并导致移动性显著减少，与居家令本身的效果相当。在倾向民主党的县比在倾向共和党的县中效果更大，在共和党州长的情况下更为明显。倾向民主党的县对共和党和民主党州长的建议的反应也更为强烈。政治党派偏见影响公民根据州长的建议自愿参与身体距离的决策。
