Title: The role of counterfactual reasoning in responsibility judgments
Abstract: To hold someone responsible, we need to assess what causal role their action played in bringing about the outcome. Causality, in turn, can be understood in terms of difference-making -- C caused E if E would have been different had C been different. In previous work, the counterfactual of “C being different” is often construed as “C being absent”. Here, we explore how in social situations, this counterfactual can be alternatively construed by imagining how a different person would have acted in the same situation. We propose a model that formalizes this idea of counterfactual replacement by comparing what actually happened with what would have happened had the person of interest been replaced by someone else. The model then predicts responsibility to the extent that the replacement person would likely have changed the outcome. We test this model against people’s responsibility judgments in three different paradigms across several experiments.
