You don’t have to lose in order for me to win

• Prisoners dilema strategies that win:

  • Nice
  • Forgiving
  • Retaliatory (strike back right away)
  • Clear
  • (Nice guys really can finish first?)
  • This is all given infinite time (but time is very important)

• I think everybody agrees with this - but also you can “show” that something is tit for tat even if it is not

• Explains cooperation

• Life and death matters

• Tit for tat vs not tit for tat could set off a constant retaliations

  • So why not firgive 10% more often (9/10 times don’t defect after a defection)

• Tit for tat never wins 1v1

• Difference between life and sports?

  • Zero sum (1v1) where tit for tat would always lose and always defect would always tie or win
  • Life is not zero sum? Cooperation pays? Why does cooperation pay?
    • What are win/win situations?
  • In a world where you play games vs a lot of people you will come across a lot of different strategies and you don’t have to win against everybody (especially if cooperation produces more points)
  • In the short term:
    • The environment shapes the player
  • In the long run:
    • The players shape the environment
  • THE GOAL IS TO ACCUMULATE POINTS - NOT TO DEFEAT THE OPPONENT
