Gender Differences in Overconfidence
This graph measures the CDF of subjects' overconfidence about their performance relative to others. Overconfidence subtracts actual percentile performance (which ranges from 0 to 100) from predicted percentile performance (also from 0 to 100). Positive numbers indicate overconfidence.
The results show a clear pattern of male overconfidence: men are 13 percentage points more likely to be overconfident than underconfident, while women are similarly likely to be overconfident or underconfident.
