Lie Machines: How to Save Democracy from Troll Armies, Deceitful Robots, Junk News Operations, and Political Operatives

Philip Howard — founding director of the Oxford Internet Institute's Computational Propaganda Project and one of the field's leading empirical researchers — synthesises a decade of research into the infrastructure of political disinformation. Lie Machines examines the full production chain of modern disinformation: the political operatives who commission it, the junk news operations that produce it, the bot networks and troll farms that amplify it, and the social media platforms whose algorithmic architecture distributes it. The book is based on the largest comparative study of computational propaganda ever conducted, spanning dozens of countries.

Howard's central contribution is the concept of the lie machine as an integrated system rather than a collection of individual bad actors. Disinformation at scale requires coordination across multiple components — content production, amplification infrastructure, targeting data, and platform exploitation — and effective counter-disinformation requires understanding and disrupting each component. For practitioners designing institutional responses to information threats, this systemic perspective is more operationally useful than accounts that focus on individual actors or specific incidents. Clear, evidence-based, and practically oriented.
