Labels used on this site
Descriptive review labels, not a scientific certification and not candidate scores.
- Stated position
- What the subject has said they support or oppose.
- Promise or commitment statement
- A statement promising a future action or result. A promise is not evidence the result will occur.
- Proposal
- A specific plan, bill, or policy put forward. Proposed is not enacted.
- Recorded vote
- An attributable recorded vote, with context.
- Other documented action
- An order, administrative action, filing, or other attributable act.
- Implementation evidence
- Evidence that an enacted measure was carried out. Enactment is not implementation.
- Measured outcome
- A measured result. An outcome during a term is not proof of personal causation.
- Forecast or modeled estimate
- A projection or modeled estimate, attributed to its author.
- Attributed interpretation
- An interpretation attributed to a named source, not an observed fact.
- Evidence gap
- A question the reviewed sources do not yet answer.
- High confidence
- Strong direct/authoritative evidence for the defined claim, with applicable context and no unresolved material conflict undermining it.
- Moderate confidence
- Credible evidence, but meaningful applicability, measurement, corroboration, or attribution limits remain.
- Limited confidence
- Sparse, indirect, incomplete, or materially contested evidence; the limitation is explained.
- Insufficient evidence
- Available research cannot support a substantive finding; the gap is shown, not a forced conclusion.
