Confidence & Uncertainty

Confidence you can inspect.

Evidence levelE1Architecture Defined

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

Low confidence is never shown in red.Limitation: The value is invented. Confidence here is a way of reading, not a score.

A worked example

Three steps from a synthetic scenario, in relative terms.

A worked example Synthetic example
StepWhat is seenWhat is stated
1A second source joinsConfidence rises, and the reason is named
2Data stops arrivingConfidence falls gradually, not at once
3No source covers an areaThe area is shown as unknown, not as clear

Confidence and its drivers CH04Data status: Synthetic dataEvidence level: E0 · ConceptQuestion answered: How did confidence evolveA line with a shaded band shows confidence rising when a new source joins and falling when one drops out. The band narrows as more sources agree.Limitation: The band is a drawn example of uncertainty, not a computed interval.

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.

Evidence and maturity

This page claims nothing above the level of the projects it rests on.

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.
