A Confidence Calibration Exercise
Do you know what you know?
Answer each true/false question below, then set the slider to how confident you are in your answer. 50% means you have no idea (a coin flip between the two choices); 100% means you are completely certain.
Good judgment is not just being right. It is knowing how likely you are to be right. Skip any question you like; only answered questions are scored.
How you stack up
Everyone who has completed the quiz, on the same three measures. Bars show where people land; the dashed line is the typical person and the red diamond is you.

What happened at each confidence level
For every level of certainty you claimed, the gray bar is that stated confidence and the red bar is how often you were actually right. When red falls short of gray, that is overconfidence.
