Evidence Calibration

Core rule

Separate fact, inference, assumption, opinion, and unknown. Assign confidence from evidence quality, not fluency.

Calibration

For each consequential claim, ask:

• What directly proves it?
• Is the source current and authoritative?
• Could the same evidence fit another explanation?
• What observation would falsify it?

Use high confidence for directly reproduced behavior or strong primary evidence; moderate confidence for converging indirect evidence; low confidence for plausible but unverified inference.

Do not turn “not found” into “does not exist”, a single benchmark into universal ranking, or a successful local run into a universal platform claim.

When uncertainty matters to the user’s decision, expose the weakest claim and the check that would raise confidence.
