Much like an overexploited ecosystem, the increasingly polarized political landscape in the United States — and much of the world — is experiencing a catastrophic loss of diversity that threatens the resilience not only of democracy, but also of society, according to a series of new studies that examine political polarization as a collection of complex ever-evolving systems.

Fifteen interdisciplinary teams of political scientists and complex systems theorists in the natural sciences and engineering explored how polarization is produced and influenced over time by the actions and interactions of individual voters, people in power, and various social networks. Ultimately, as social interactions and individual decisions isolate people into only a few intractable camps, the political system becomes incapable of addressing the range of issues — or formulating the variety of solutions — necessary for government to function and provide the services critical for society.

The studies were published Dec. 6 in a special issue of the Proceedings of the National Academy of Sciences that stemmed from a collaboration between Princeton University and Arizona State University (ASU) and includes several papers led by Princeton researchers.
