!Prisoner Dilemma

• Consider Ali perspective
  • If Bo testify. The best action for Ali is to testify with -5 cost
  • If Bo refuse. The best action for Ali is to testify with 0 cost
  • In both cases, the best action is always to testify → Dominant strategy
• When all players choose the Dominant strategy, this results in a Dominant strategy equilibrium
