Information Gerrymandering and Undemocratic Decisions

A Frontiers in Science Lecture by Joshua Plotkin, University of Pennsylvania

 

Many Americans receive their news and form political opinions through social media. But social media platforms are not shaping up to be the utopian spaces for human connection their founders once hoped. Instead, the Internet has introduced phenomena that can influence national elections and even threaten democracy. This talk will describe recent findings on "information gerrymandering” — how the structure of a social network can profoundly bias collective decisions. Evidence of these effects is found in large-scale human experiments, real-world social-media networks, and networks of legislative actions in the US Congress. These results motivate questions about policy.
