Information, Fake News, and Social Networks

Welcome to the site of the research project "Information, Fake News, and Social Networks", funded by the German Research Foundation (DFG).  Over the last two decades, the digital revolution has fundamentally changed the way people consume news.  These developments have facilitated the spreading of "fake news" and disinformation, in particular on social media. In this project, we thoroughly investigate strategic communication in uncertain environments to develop a comprehensive theory of fake news and disinformation.
