This paper reports from a simple natural field experiment based on an eco-nomics exam. Part of the exam consisted of 30 multiple choice questions, where the students obtained 1 point per correct answer while 1 point was deducted for each in-correct answer. We find no significant gender differences in overconfidence, irrespec-tive of how we measure it, i.e., whether we regard the number of questions answered, the number of questions answered incorrectly or the answering patterns for the most difficult questions. Hence, the data provides no support for the frequently proposed hypothesis that men are more overconfident than women.
