To push or not to push? Affective influences on moral judgment depend on decision frame

People’s moods can influence moral judgment. Such influences may arise because moods affect moral emotion, or because moods affect moral thought. The present study provides evidence that, at least in the footbridge dilemma, moods affect moral thought. The results of two experiments are reported in which, after induction of positive, negative, or neutral moods and presentation of the footbridge scenario, participants were asked one of two differentially framed closing questions. In the active frame, participants were asked whether they would be active and push the man, making thoughts about pushing accessible; in the passive frame, they were asked whether they would be passive and not push the man, making thoughts about not pushing accessible. The results show that affective influences on moral judgment depended on participants’ decision frame. Compared to neutral moods, positive moods induced utilitarian responding – i.e., deciding to push – in the active decision frame, but induced nonutilitarian responding – i.e., deciding to not push – in the passive decision frame; in negative moods, exactly the opposite picture arose. The results suggest that people’s moods affect moral judgment by conferring value on moral thought. Positive moods promote and negative moods inhibit accessible thoughts.
