Through the Grapevine: Socially Transmitted Information and Distorted Democracy
In this book, I argue that learning about politics through the proverbial grapevine fuels distorted democracy. Distorted democracy is marked by an underinformed, polarized, and engaged public. Analyzing a collection of nearly a dozen experiments, original survey data, and a new dataset of over 180 million comments on over 5 million Tweets by media outlets, I show that as people discuss what they read in the news, the actual information exchanged in conversations becomes heavily distorted: it becomes sparse, carries more partisan bias, and is somewhat less accurate. This means that when individuals primarily learn about politics from others instead of from the news, as about one-third of the American public does, they are likely to be exposed to distorted information that can affect their decision-making. Although they can sometimes learn more than they would had they received no information at all, when this casually informed segment of the public relies on social information, they are more likely to believe misinformation and hold more extreme and sorted policy preferences. What is more, the changes in content as information flows through the grapevine can also be mobilizing, leading to a world in which a large segment of the public is politically engaged based on distorted information.
