Ego depletion theory postulates that the ability to exert self-control depends upon the availability of a limited mental resource. In this experiment, we investigated the effects of ego depletion on risky decision-making. We also examined the moderating effect emotional intelligence may have on this relationship. First, participants completed a trait emotional intelligence questionnaire and a self-control task. This was followed by a mood questionnaire and a series of risky-decision scenarios. Results showed (1) participants who were depleted made more risky decisions than non-depleted participants, (2) no differences in perceived task effort between groups, (3) no evidence of a moderating effect for emotional intelligence and (4) depleted participants were more aroused and their moods were more negative than non-depleted participants. Taken together, these results imply that ego depletion enhances the inclination to take risks and that decisions involving risks should not be made under these conditions.
