Test a Belief at Its Edges

A useful idea for examining a belief: look for the case where its words stop fitting.

Try this three-step check:

1. State the claim plainly—for example, “More practice means more progress.”
2. Imagine a case where practice increases but the result you care about does not.
3. Ask what that example reveals: Is the claim too broad, is “progress” unclear, or is practice only one part of the explanation?

This doesn’t prove the belief false. It helps separate a value—what kind of progress matters—from a factual claim about what causes it. That distinction can make the next question easier to investigate, instead of arguing over a sentence that means different things to different people.
