How to Think in Credences
Thinking in credences means replacing all-or-nothing belief with explicit degrees of confidence.
Start With a Number or Range
The first skill is to stop hiding behind yes-or-no belief when the evidence is graded. You do not always need a precise number, but you do need a sense of strength: barely leaning, moderately confident, highly confident, or nearly certain.
A range is often better than fake precision. Saying "I am somewhere between 0.6 and 0.7" is more honest than pretending to know you are at exactly 0.64.
Name What Would Move You
A credence becomes more rational when it is updateable. Ask what evidence would raise it, lower it, or leave it unchanged. If no possible evidence would move the credence, you may be dealing with identity protection rather than inquiry.
Practice
Choose three ordinary claims each day and assign rough credences. Then write one sentence explaining the evidence and one sentence naming what would change your mind. The goal is not mathematical performance. The goal is to make confidence answerable.
