What do We Know about Social Media, Political Polarization, and Political Disinformation?

The Hewlett Foundation has just published a report that provides an overview of the current state of the literature on the relationship between social media, political polarization, and political disinformation. The report was coordinated by Josh Tucker and features contributions from Andrew Guess, Pablo Barberá, Alexandra Siegel, Sergey Sanovich, Denis Stukal, Brendan Nyhan, and myself. Importantly, the report also identifies key gaps in our knowledge of these phenomena and the kinds of data we need to overcome them.

Here is the executive summary:
