Confidence Levels

Confidence Is Not a Mood

Confidence often feels like an internal intensity, but epistemically it should be a relation between a claim and its support. A calm person can be overconfident; an anxious person can be correct. The feeling of certainty is not the same as warrant for certainty.

A confidence level should answer a practical question: how much risk of being wrong am I implicitly accepting by holding or acting on this belief?

Useful Ranges

Low confidence marks live uncertainty. Moderate confidence permits leaning without closure. High confidence permits strong action but should remain updateable. Near certainty should be rare and reserved for claims with overwhelming support, definitional truths, or extremely stable background knowledge.

The model encourages this range-sensitive language because many failures come from using high-confidence behavior on medium-confidence evidence.

Confidence and Stakes

The same confidence level can justify different actions under different stakes. A 70 percent credence may justify bringing an umbrella, but not convicting someone of a crime. Credence and decision threshold are related but distinct.

Keeping that distinction visible prevents a common error: pretending to be more certain than one is because action is required.
