ABSTRACT
Social dilemmas are ubiquitous. Any situation in which (a) people are rewarded more for selfish choices (in the short-term) than for cooperative choices and (b) everyone is better off when everyone makes cooperative choices than when everyone makes selfish choices, is a social dilemma (Dawes, 1980). They permeate our home lives (e.g., clean up or leave it to others), daunt public policymakers and politicians (e.g., exploit a natural resource now for short-term gain or manage it conservatively to preserve it), and pervade every work group (e.g., put in effort and pull your weight or free-ride on others’efforts).
