Conflict in moral and nonmoral decision making: an empirical study coupled with a computational model.

Résumé

While moral psychology research has extensively studied decision making using moral dilemmas, such high-conflict situations may not fully represent all moral decisions. Moreover, most studies on the effect of conflict have focused on nonmoral decisions, and it is unclear how it applies to the moral realm. The present mixed-method research investigates how conflict impacts moral compared to nonmoral decision making. In a preregistered empirical study ( N = 42 ), participants made moral and nonmoral decisions with varying levels of conflict while their mouse trajectories were recorded. Results indicate that moral decisions were more stable in the presence of conflict, while still seeking compromise. In addition, decisions were more affected when conflict got higher. Mouse-tracking data further indicate that some factors are impacting the decision process earlier than others, supporting the relevance of tracing methods to dig into finer-grained decision dynamics. We also present a computational model that aims to capture decision mechanisms and how conflict and morality influence decision making. The model uses dynamic neural fields coupled with sensorimotor control to map a continuous decision space. Two model versions were compared: one with greater perceptual weight for moral information, and another with earlier processing of moral versus nonmoral information. The simulated data more successfully reproduced empirical patterns for the second version, thus providing insights into the underlying decision processes for both moral and nonmoral decisions, in the presence of conflict or not.
