Do as I say, don't do as I do:differences in moral judgments do not translate into differences in decisions in real-life trolley problems

Many people judge that it is permissible to harm one person in order to save many in some circumstances but not in others: it matters how the harm comes about. Researchers have used trolley problems to investigate this phenomenon, eliciting moral judgments or behavioral predictions about hypothetical scenarios where five people can be saved at the cost of harming one other person. We operationalized trolley problems in the laboratory, with economic incentives and real-life consequences, allowing us to observe not only judgments but actual decisions. We varied whether the five were saved by clicking a switch that diverted the harm to the one or by dragging the one in front of the harm. We found differences in moral judgments between the two tasks, but no differences in behavior. The judgments of actors and observers also differed, with observers judging it more right to act. Our results suggest that the difference between moral judgments and actions arises because participants think that doing the right action still involves doing something morally discreditable, and that the morality of taking action does not exhaust the normative reasons for acting.
