The charge
On hard tasks we are usually too confident, and on easy tasks we are often not confident enough.
How it operates
Confidence does not move as much as true task difficulty does, so judgments drift toward a middle level even when performance does not.
Logged incidents
- Incident 01
A turnaround plan for a troubled business is given a 70% success estimate even though similar cases rarely work.
- Incident 02
A hiring panel feels only mildly confident about rejecting an obviously unqualified candidate.
- Incident 03
Forecasters give similar confidence levels to simple and extremely complex product bets.
What to watch for
Look for confidence ranges that barely change across clearly different task difficulties. Ask: 'Have I adjusted confidence enough for how hard this really is?'
Recommended action
Track calibration curves by task difficulty and use forecast training with scored probabilities.
