Deontology and Utilitarianism in Real Life: A Set of Moral Dilemmas Based on Historic Events.

Abstract

Moral dilemmas are frequently used to examine psychological processes that drive decisions between adhering to deontological norms and optimizing the outcome. However, commonly used dilemmas are generally unrealistic and confound moral principle and (in)action so that results obtained with these dilemmas might not generalize to other situations. In the present research, we introduce new dilemmas that are based on real-life events. In two studies (a European student sample and a North American MTurk sample, total N = 789), we show that the new factual dilemmas were perceived to be more realistic and less absurd than commonly used dilemmas. In addition, factual dilemmas induced higher participant engagement. From this, we draw the preliminary conclusion that factual dilemmas are more suitable for investigating moral cognition. Moreover, factual dilemmas can be used to examine the generalizability of previous results concerning action (vs. inaction) and concerning a wider range of deontological norms.
