Why do people seem to be more utilitarian in VR than in questionnaires?

Abstract

Several experimental studies on moral judgment and moral decision-making show that in virtual reality people tend to make more “characteristically utilitarian” decisions than when responding to standard questionnaires. An explanation of this phenomenon that has been considered by many authors states that the feature of VR studies that is responsible for this effect is the visual salience of the harmful consequences of “deontologi cal” decisions. The present paper makes three points, the first of which is theoretical: we argue that this explanation, which draws from Cushman’s dual-process account of moral judgment, is in fact not coherent with this account’s predictions with respect to behavior in VR. The second point is that this explanation does not sufficiently explain the existing empirical findings concern ing the footbridge dilemma because these studies differ in important aspects of experimental design from studies on the switch dilemma. The third point is empirical: we present two original VR studies that were designed to check the robustness of the increased “utilitarian” tendency and directly test the explanation that is based on the visual salience of harmful consequences. The results of the experiments provide evidence that the effect is quite robust but the proposed explanation is inadequate
