Prisoner's Dilemma Simulator

Sam's Thought Process:

• If John stays silent:
  • Better for Sam to betray (Sam's reward: 0)
  • Than for Sam to stay silent (Sam's reward: -1)
• If John betrays:
  • Better for Sam to betray (Sam's reward: -2)
  • Than for Sam to stay silent (Sam's reward: -3)

Conclusion: It only makes sense for Sam to betray. John thinks the same way.
