Shared Intentionality and the State of Nature: Punitive Sentiment in the Psychology of Cooperation

The shared intentionality hypothesis aims to explain the evolution and psychology of human cooperation, but it lacks the means to deal with the free-rider problem. To resolve thisproblem, I propose that the shared intentionality hypothesis can be supplemented with an account of how punitive sentiment in humans evolved as a psychological mechanism for strong reciprocity. Supplementing the shared intentionality hypothesis in this manner affords us additional insight into the normative nature of human cooperation.
