Stag Hunt
Coordinate with a stranger on a high-payoff hunt or play it safe.
Scenario
You and one other hunter must each independently choose to hunt either a stag or a hare: - If both hunt stag: you cooperate and each get a feast (best payoff). - If both hunt hare: you each get a small meal (modest payoff). - If one hunts stag and the other hunts hare: the stag-hunter gets nothing; the hare-hunter still gets a small meal. You cannot communicate. The other hunter is rational but a stranger.
