      • Common knowledge
      • Bayesian common knowledge
      • The ideal situation
    • Response to the assumptions
    • You can't agree to disagree
    • Which of this assumptions is wrong?
      • Fragile versus robust results
      • Common knowledge
      • We need to know that we disagree
      • We have to know what you will say next

      • Irrelevance of information
    • Common priors
      • Prior definition
      • Why not let people believe different things if they know nothing?
      • Not all priors produce believes that you would endorse
      • The process to produce the prior
      • We are not special
      • Example: Two astronomers
    • Lying or misunderstanding?
    • The complications of the theory
    • We usually believe we are honest
    • Why do people disagree to the theory?
      • Ego
      • We have different goals than believing on the truth
        • We don't like to admit it
        • We can sense it on other people

    • How do you separate believingand knowing?
    • We choose to believe things, whether they are true or not. How could that explain disagreements?
    • What do time and effort relate with disagreements?
    • Is it better to reach a bad agreement than a great lawsuit?

About this video

Robin Hanson explains his point of view about disagreements. Hanson's mathematical orientation leads his opinions to a peculiar point of view: analyzing disagreements as a theorem. Hanson supports this idea using the Bayesian model, which he points out as a valuable tool for analyzing arguments.
