How Information Creates Power: Yuval Noah Harari on Democracy, Propaganda and AI

In Chapter 5 of Nexus, Yuval Noah Harari examines how information networks shape political power, from ancient empires and mass propaganda to social media and artificial intelligence.

Mark and Jeremy discuss why information doesn’t automatically produce truth, and how both democracies and totalitarian systems use stories, institutions and communication technologies to organise society. The central issue is who controls the network, who can challenge its claims and whether errors can be corrected.

In this episode, we discuss:

• How information networks create and maintain political power

• Why democracy depends on distributed information and self-correction

• How totalitarian systems centralise information and suppress feedback

• What ancient societies can teach us about collective decision-making

• How Roman rulers such as Nero used propaganda to protect authority

• Why pamphlets and printing helped destabilise established political systems

• How social media feeds influence political beliefs and public debate

• Whether AI-generated memes and propaganda could reshape political movements

• How artificial intelligence could strengthen democratic or authoritarian systems

• Why independent discussion groups and institutions still matter

Harari’s argument is that the struggle between democracy and totalitarianism is partly a struggle between different kinds of information networks. Democracies tolerate competing accounts and mechanisms for correcting mistakes. Dictatorships concentrate control and punish contradiction.

This conversation examines what happens when AI systems begin producing political messages, filtering information and influencing public opinion at a scale no earlier propaganda system could achieve.
