CORE DEFINITION

Two people go hunting. If they cooperate to hunt a stag, each gets a lot of meat (high payoff); if they hunt a hare alone, they are guaranteed to catch a hare to fill their stomach (low payoff, but safe). The problem is that hunting a stag requires perfect coordination; if one person goes for a hare midway, the stag hunter gets nothing. -

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Trade-off between safety and cooperation. - Difference from the Prisoner's Dilemma (where betrayal is the dominant strategy): In the Stag Hunt, cooperation is win-win but requires high trust. It explains why many good projects (stag hunting) are not undertaken; everyone flocks to low-end markets (hare hunting). Trust is the only lever that lifts everyone from the 'hare equilibrium' to the 'stag equilibrium'.

anchor

Anchor fast decisions

A two-person hunting game conceived by Rousseau: cooperative stag hunting yields high payoff but requires coordination, while solitary hare hunting yields low but safe payoff. There are two Nash equilibria: both hunt stag (high-payoff cooperation) and both hunt hare (low-payoff safety). The choice depends on expectations about the partner's cooperative belief (trust), not on unilateral dominance.
