Behavioral games
Run a Stag Hunt Game
Study coordination between a high-value joint outcome and a safer individual action.
The basic idea
Stag Hunt represents assurance and strategic coordination: mutual stag choice gives the largest coordinated payoff, while hare is safer when a player doubts the other will coordinate. The payoff matrix should preserve both the reward for coordination and the relative security of hare.
Compare whether models and humans coordinate on stag after no communication, selected prior messages, or a deliberative exchange.
How to do it
- 1
Assign two seats and set the stag, hare, and mismatch payoffs.
- 2
Check that mutual stag is attractive while hare remains the safer response to expected noncoordination.
- 3
Choose identity, communication, repetition, and feedback conditions deliberately.
- 4
Report action pairs, successful coordination, payoffs, and transitions between strategies across rounds.
What to watch for
- Different payoff matrices can shift risk dominance.
- Communication turns the study into a communication-and-coordination treatment.
- Repeated games can reflect learning or reputation rather than one-shot assurance.
What a useful result looks like
The result distinguishes successful high-payoff coordination, safe-action coordination, and failed coordination for each configured actor pair.
