Confidence & Uncertainty
Confidence you can inspect.

The functional gap
A single number called confidence invites trust it has not earned. A reader needs to know what the number rests on, and what would change it.
From inputs to outputs
Takes in
- The contributions behind a state
- The age and quality of each observation
- Gaps and disagreements between sources
Does
States confidence together with its reasons and shows how it changed. Unknown stays a state of its own and is never turned into zero or into safe.
Hands on
- A confidence statement with its reasons
- The change in confidence over time
- Unknown shown as unknown
A worked example
Three steps from a synthetic scenario, in relative terms.
| Step | What is seen | What is stated |
|---|---|---|
| 1 | A second source joins | Confidence rises, and the reason is named |
| 2 | Data stops arriving | Confidence falls gradually, not at once |
| 3 | No source covers an area | The area is shown as unknown, not as clear |

- Uncertainty band
| Time (relative) | Confidence | Uncertainty band |

Confidence and uncertainty in this function
This function is the statement of confidence itself, so its own limit is simple: a stated confidence is a claim about the data, not a measurement of the world.

What this does not claim
- Confidence is not evidence; the evidence trail is a separate page.
- The page describes how confidence is stated and states no calibration result.
- A high confidence never means certainty, and unknown never means safe.
