中文摘要
这项在巴基斯坦某社交媒体平台上开展的随机实验, 衡量了两种能够完全控制虚假信息获取的处理相对于一种更标准的事后控制虚假信息方法的影响。在第一种处理中, 平台上不允许出现任何虚假信息; 在第二种处理中, 允许出现虚假信息, 但需附带官方辟谣。该实验聚焦于有关 COVID-19 的虚假信息, 并与一项在该平台上传播疫情官方信息的干预相结合。通过任一种处理控制虚假信息都会减少平台使用; 它对官方信息接触的减少幅度还超过其对虚假信息接触的减少幅度。
Abstract
This randomized experiment on a social media platform in Pakistan measures the impact of two treatments that fully control access to misinformation relative to a more standard ex-post approach to controlling misinformation. In the first treatment, no misinformation was allowed on the platform, while in the second, it was allowed with an o ffi cial rebuttal. The experiment focuses on misinformation regarding COVID-19 and is combined with an intervention to disseminate o ffi cial information about the pandemic on the platform. Controlling misinformation through either treatment reduces platform usage. It also reduces exposure to o ffi cial information by more than it reduces exposure to misinformation.
