Individual differences in the explicit power motive predict “utilitarian” choices in moral dilemmas, especially when this choice is self-beneficial

• We investigated moral decision making in hypothetical moral dilemmas
• Individual differences in the explicit power motive predicted utilitarian decisions
• This effect was even more pronounced in self-beneficial dilemmas
• The explicit power motive supersedes the previously found effect of BAS

We all face moral decisions, whether we are judges, politicians, or just riding the bus. The most well studied of these involve concerns of harming or caring for other people, which have often been researched by employing hypothetical moral dilemmas. This study investigated how the explicit power motive, more precisely the hope to gain power (h_Power), predicts decisions for these types of problems. We found that h_Power was positively related to deciding that it was morally acceptable to kill one person to save multiple others (i.e., making a utilitarian choice). In an exploratory analysis, we found that the probability of making such choices as a function of h_Power was even higher when participants’ own lives were at stake as compared to only the lives of others. These findings complement previous research showing that personality variables as well as situational factors predict moral decision making. Finding biases in moral decision making is important, as only when we know these biases we can consciously counteract them.
