This lecture analyzes a model in which two gunslingers—each armed with only a single bullet—must decide when to fire their gun at their opponent.

Takeaway Points

  1. In a proof by contradiction, we assumption something is true and then attempt to derive a result that is a contradiction.
  2. Since logic is truth-preserving, the assumption must be false. This process is useful for finding equilibria in what would otherwise be an extremely complex game.
  3. In the game theory galaxy, Han shot at the same time as Greedo.
