Confidence Calibration

Do you know what you know? Most people are systematically overconfident — high certainty on questions they get wrong. This measures the gap.

How it works
1
You'll see 20 true/false questions drawn from a general knowledge database.
2
For each question, select True or False — then rate how confident you are from 50% (coin flip) to 100% (certain).
3
At the end, you'll see your calibration score: how well your confidence tracked your actual accuracy.
A well-calibrated person who says 70% should be right about 70% of the time at that confidence level. Overconfidence means your stated probability consistently exceeds your hit rate. The goal is not to be more confident — it's to be accurate about your own uncertainty.
