Stag Hunt, Coordination
The Stag or the Rabbit
The Stag or the Rabbit is a Stag Hunt and Coordination scenario. The core lesson: High-reward cooperation requires trust, and trust requires knowing what the other person will do. You and a hunting partner can either team up to catch a stag (big reward, but only if both show up) or each catch a rabbit alone (small reward, guaranteed). Neither of you can communicate. DecisionPlay maps the players, payoffs, and equilibrium dynamics that shape how this situation typically resolves.
The situation
You and a hunting partner can either team up to catch a stag (big reward, but only if both show up) or each catch a rabbit alone (small reward, guaranteed). Neither of you can communicate. Do you hunt the stag?
Background
The Stag Hunt is the cleanest model of the tradeoff between risky cooperation and safe solo action. Unlike the Prisoner's Dilemma, both players prefer the cooperative outcome. The problem isn't misaligned incentives, it's coordination under uncertainty. This shows up in startup cofounding, union organizing, political coalition-building, and roommate cleanliness norms.
What this reveals
Trust is a self-fulfilling prophecy
When people expect cooperation, they cooperate, and cooperation happens. When they expect defection, they defect preemptively, and cooperation collapses.
How to counter it: In situations where mutual benefit is possible, invest early in signaling your own cooperative intent. The other person is deciding based on what they think you'll do.
A question to sit with
Where in your life are you choosing the rabbit because you don't trust someone to show up for the stag? What would it take to actually test that assumption?
