Network Propaganda: Manipulation, Disinformation, and Radicalization in American Politics

One of the most rigorously empirical books produced in the field. Benkler, Faris and Roberts — researchers at Harvard's Berkman Klein Center — analysed four million stories shared on social media across the 2016 US election cycle to map, with data, the structure of the American information ecosystem. Their findings challenged several prevailing assumptions: the problem was not symmetric across the political spectrum, it was not primarily caused by Russian interference, and it was not reducible to social media algorithms. The dominant driver was the asymmetric radicalisation of the right-wing media ecosystem, which had over decades developed an internal logic that prioritised outrage and tribal identity over factual accuracy.

Network Propaganda is important for practitioners because it insists on structural analysis over event-based explanation. Understanding why disinformation takes hold in a particular information environment requires understanding the architecture of that environment — its media outlets, its audience behaviours, its platform dynamics — not just the tactics of individual operators. The methodology is transferable: the same network mapping approach can be applied to any national or institutional information environment to identify vulnerabilities before they are exploited.
