Overconfidence as a social bias: Experimental evidence

  • Proeger, Till
  • Meub, Lukas
Registered author(s):

    The overconfidence bias is discussed extensively in economic studies, yet fails to hold experimentally once monetary incentives and feedback are implemented. We consider overconfidence as a social bias. For a simple real effort task, we show that, individually, economic conditions effectively prevent overconfidence. By contrast, the introduction of a very basic, purely observational social setting fosters overconfident self-assessments. Additionally, observing others’ actions effectively eliminates underconfidence compared to the individual setting.
