Variance misperception explains illusions of confidence in simple perceptual decisions
Confidence in a perceptual decision is a judgment about the quality of the sensory evidence. The quality of the evidence depends not only on its strength ('signal') but critically on its reliability ('noise'), but the separate contribution of these quantities to the formation of...

Confidence in a perceptual decision is a judgment about the quality of the sensory evidence.

We studied subjective confidence reports in a multi-element perceptual task where evidence strength and reliability could be manipulated independently.
