Is Journalistic Truth Dead? Measuring How Informed Voters Are about Political News
中文摘要
为考察美国新闻信息的一般模式，我们结合了识别重大政治新闻故事的方案、11次月度调查（15,000名参与者）以及新闻辨别模型。当面对一条真实新闻故事和一条虚假新闻故事时，47%的受试者确信选择真实新闻故事，3%的受试者确信选择虚假新闻故事，其余一半则不确定。社会经济差异与选择真实新闻故事的概率的大幅变动相关。个体与新闻故事之间的党派一致性具有影响，但其影响量级最多小一个数量级。(JEL D72, D83, L82)
Abstract
To investigate general patterns in news information in the United States, we combine a protocol for identifying major political news stories, 11 monthly surveys with 15,000 participants, and a model of news discernment. When confronted with a true and a fake news story, 47 percent of subjects confidently choose the true story, 3 percent confidently choose the fake story, and the remaining half are uncertain. Socioeconomic differences are associated with large variations in the probability of selecting the true news story. Partisan congruence between an individual and a news story matters, but its impact is up to an order of magnitude smaller. (JEL D72, D83, L82)
