Adjudicate a stratified disagreement sample using: Which evidence most directly resolves that uncertainty?
A stratified adjudication sample with an operational rubric directly distinguishes ambiguous guidance from model error.
The question
A financial-document classifier has substantial disagreement among annotators, especially for handwritten forms. Before approval, the team must determine whether disagreement reflects unclear labeling rules rather than model failure. Which evidence most directly resolves that uncertainty?

- Compute overall accuracy on a larger labeled sample.A larger sample may improve precision, but it does not reveal whether annotators applied inconsistent or ambiguous labeling rules.
- Compare model outputs with last year’s production labels.Historical labels may reproduce the same unresolved disagreement and cannot independently establish which interpretation is correct.
- Adjudicate a stratified disagreement sample using an operational rubric. ✓Adjudication exposes disagreement causes, while stratification checks whether ambiguity concentrates in document types or subgroups.
- Run a privacy review of every document before measuring label agreement.Privacy review may be necessary for document handling, but it does not resolve whether labels were consistently interpreted.
The trap
When labels themselves are uncertain, inspect and adjudicate disputed examples before relying on model metrics. How to remember it
