Field notes
The sample calibration display compares a user's 70% confidence rating with a 63% observed success rate and labels the gap as overconfidence. Another example carries base-rate reasoning from medical testing into face recognition, illustrating how a high accuracy figure can still produce many false positives when the relevant group is small.
