Methods
Methods note: communicating quantification confidence without false precision
How to present uncertainty and confidence bands in calculators and dashboards without weakening decision clarity.
Quantification interfaces often fail in one of two ways: they either imply more certainty than the model supports, or they present uncertainty so vaguely that users cannot act on the result. Both outcomes weaken trust.
Communicating confidence well
A better approach is to communicate confidence in structured terms: what assumptions matter most, what range is reasonable, and where the result should be treated as directional rather than definitive.
The goal is not to remove uncertainty. It is to make uncertainty legible enough that better decisions remain possible.
