How Information Systems Shape Truth and Power: Yuval Noah Harari on Religion, Books and AI

In Chapter 4 of Nexus, Yuval Noah Harari examines how information systems shape belief, authority and our understanding of truth.

Mark and Jeremy discuss how religious texts, books and institutions created durable systems for organising knowledge and legitimising power. They also examine the difference between traditions that claim access to unquestionable truth and the scientific method, which treats human error as unavoidable and correction as essential.

In this episode, we discuss:

• How religious narratives create legitimacy and political authority

• Why written texts transformed the control and transmission of knowledge

• How books became tools for preserving doctrine and enforcing belief

• What the Oracle of Delphi reveals about information and power

• How witch hunts emerged from collective belief and institutional reinforcement

• Why false narratives can persist even when evidence is weak

• How the scientific method changed society’s approach to truth

• Why admitting error is central to reliable knowledge systems

• What historical information networks can teach us about AI and algorithms

• How automated systems could strengthen or distort modern narratives

  
  

Harari’s argument is that information systems don’t merely describe reality. They also create the stories, institutions and categories through which people interpret it.

This conversation examines what religion, books, witch trials and science reveal about the relationship between truth and power, and what those lessons mean in an age increasingly shaped by artificial intelligence.
