The widespread need for standardized moral dilemmas has been increasingly
motivated by the recent criticism raised against the stimulus material employed by
Greene et al. (2001). The present study aimed at presenting a novel and standardized
set of moral dilemmas, controlled for some relevant features that affect people's moral
judgment. Specifically, in this study we provide the following normative data for 75
moral dilemmas (60 experimental dilemmas and 15 filler dilemmas): a) the percentages
of affirmative responses to the resolution of the dilemma, b) the decision times, c) the
judgments of moral acceptability to the resolution of the dilemma, and d) the affective
ratings of Valence and Arousal.
