Overconfidence bias is the most thoroughly documented cognitive bias in decision-making research. It manifests in three forms:
1. Overprecision: Being too certain your estimates are correct 2. Overplacement: Believing you perform above average (90% of drivers think they're above-average drivers) 3. Overestimation: Believing your performance will be better than it actually turns out
Overconfidence has real-world costs. Studies of physicians, lawyers, and engineers all show systematic overconfidence in their domain predictions. In financial contexts, overconfident traders make 45% more trades and earn 3.7% less annually than calibrated peers (Barber & Odean, 2001).
MindFrame's calibration training directly targets overconfidence by giving you precise, immediate feedback on the gap between your stated confidence and your actual accuracy.
