The safest time to fly: pandemic response in the era of Fox News
研究发现，美国保守派媒体福克斯新闻的更多曝光导致人们在新冠疫情国家紧急状态后减少出行和居家概率的下降幅度更小，表明有偏见的媒体可能通过影响行为对防疫产生危害。
We document a causal effect of the conservative Fox News Channel in the USA on physical distancing during COVID-19 pandemic. We measure county-level mobility covering all US states and District of Columbia produced by GPS pings to 15-17 million smartphones and zip-code-level mobility using Facebook location data. Using the historical position of Fox News Channel in the cable lineup as the source of exogenous variation, we show that increased exposure to Fox News led to a smaller reduction in distance traveled and a smaller increase in the probability of staying home after the national emergency declaration in the USA. Our results show that slanted media can have a harmful effect on containment efforts during a pandemic by affecting people's behavior.
