The Stag Hunt and Social Cooperation
Although most authors focus on the prisoner's dilemma as the game that best represents the problem of social cooperation, some authors believe that the stag hunt represents an equally (or more) interesting context in which to study cooperation and its problems (for an overview see Skyrms 2004).
There is a substantial relationship between the stag hunt and the prisoner's dilemma. In biology many circumstances that have been described as prisoner's dilemma might also be interpreted as a stag hunt, depending on how fitness is calculated.
| Cooperate | Defect | |
| Cooperate | 2, 2 | 0, 3 |
| Defect | 3, 0 | 1, 1 |

It is also the case that some human interactions that seem like prisoner's dilemmas may in fact be stag hunts. For example, suppose we have a prisoner's dilemma as pictured in Figure 3. The payoff matrix would need adjusting if players who defect against cooperators might be punished for their defection. For instance, if the expected punishment is -2, then the imposition of this punishment turns the above prisoner's dilemma into the stag hunt given at the introduction.

Famous quotes containing the words stag, hunt, social and/or cooperation:
“What was dancing to you then?
We went from the high gate away
To a black hill the other side of men
Where one wild stag stared
At the going day.”

“Children, then, acquire social skills not so much from adults as from their interactions with one another. They are likely to discover through trial and error which strategies work and which do not, and later to reflect consciously on what they have learned.”
—Zick Rubin (20th century)
“We fatuously hoped that we might pluck from the human tragedy itself a consciousness of a common destiny which should bring its own healing, that we might extract from life’s very misfortunes a power of cooperation which should be effective against them.”
