Does it matter who pulls the switch? Perceptions of intentions in the trolley dilemma

This research examines the automatic moral and intentional inferences that third parties generate as a function of outcomes for the actor. Participants were asked about the moral acceptability of redirecting a train to save five lives by sacrificing one, as well as the intentions of the person directing the train, and the consequences of doing so. Actor position was varied with respect to whether the person redirecting the train stood to benefit by doing so. Across four studies in international and US samples, participants rated the redirection as less morally acceptable or more punishable when the actor redirecting the train was saving their own life in the process. The implications of these findings for moral claims are discussed. (C) 2014 Elsevier Inc. All rights reserved.
