Persuadable perceptions: the effect of media content on beliefs about corruption
结合大型家庭调查数据与受访者当日接触腐败新闻的准随机暴露，发现新闻数量增加一个标准差会使腐败感知上升3.5%，且主要受非具体事件新闻影响，符合说服机制。
SUMMARY We study the impact of news content on individuals’ perceptions about corruption. To this purpose, we combine individuals’ beliefs about the likelihood that corruption events may occur in everyday life, as obtained from questions introduced in a large household survey, with their as-good-as-random exposure to corruption-related news on the date of the interview. Results show that a 1 SD increase in the number of corruption news items raises corruption perceptions by 3.5%. Consistently with a mechanism of persuasion, perceptions respond mainly to news not related to specific corruption events rather than to those reporting on arrests, investigations or convictions.
