Interindividual-intergroup discontinuity in the domain of correspondent outcomes: The roles of relativistic concern, perceived categorization, and the doctrine of mutual assured destruction. *Journal of Personality and Social Psychology, 94*, 479-494. **Target of replication.** We intend to replicate the original authors finding regarding that the discontinuity effect in which groups make more competitive choices than individuals is moderated by the level of Partner Control-Joint Control (PCJC) in a given decision matrix. More specifically, we seek to replicate the finding that the discontinuity effect exists when payoffs for mutual competition are moderately low (low PCJC) and disappears when the payoffs for mutual competition are extremely low (high PC-JC). As a secondary goal, we intend to examine choice reasoning by testing two mediation models, one in which the motivation to maximize relative outcomes serves as the mediator, and one in which distrust is included as the mediator. **A prior replication criteria.** A successful replication of the target effect would find that groups make a greater proportion of corrected competitive choices than individuals with a low PC-JC Chicken matrix, and no difference is found with the high PC-JC Chicken matrix. A successful replication of the mediation effects would find that both maximizing relative outcomes and distrust mediate the moderated discontinuity effect when included in separate models. **Materials, and data.** Study materials can be found in the [study materials component][1] of this project. The study materials component includes experimenter materials, and materials for each of the four conditions. [1]:
