RESUMO

We set an experiment to track both the overconfidence and competence effects. Overconfidence is the cognitive illusion that people tend to think they are better investors than they really are. And the competence illusion refers to peopleâs willingness to bet on their own subjective judgments if compared to a fifty-fifty bet. Questionnaires were distributed to 96 (male and female) Business Administration subjects from the Catholic University of BrasÃlia, Brazil. We found evidence supportive of the overconfidence effect, but not of the competence effect, especially for the female subjects.
