Introduction
practice-index-offset: 1000Four Different Judgments
- Verifiable: Could evidence establish or disprove the claim?
- Supported: Does this passage provide evidence for it?
- True: Does reliable evidence confirm it?
- Evaluative: Does it depend on a value, preference, or standard?
A factual claim can be false. An uncited claim can still be true. An opinion can be supported by facts. Classification does not settle accuracy.
| Type | Example |
|---|---|
| Verifiable factual claim | “The library closes at 8 p.m. Tuesday.” |
| Opinion/value judgment | “The library's evening hours are convenient.” |
| Misconception | A belief contradicted by strong evidence |
| Mixed claim | “The 90-minute film is far too long.” |
Bias and Point of View
Point of view is a position. Bias is a systematic leaning that can shape selection, emphasis, interpretation, or wording. Disagreement alone does not prove bias. Look for loaded labels, omitted relevant perspectives, stereotypes, conflicts of interest, or selective samples and time frames. Bias also does not make every statement false; test the specific claim.
A Claim-Testing Routine
- Isolate the exact claim.
- Mark checkable components and value language.
- Identify evidence supplied and missing.
- Ask whether the source is positioned to know this fact.
- Corroborate consequential claims with an independent relevant source.
The new route adds two stops and is a terrible use of public funds.
“Adds two stops” is verifiable. “Terrible” evaluates according to unstated criteria. Evidence might strengthen the opinion but would not make that value word purely factual.
Corroborating a Contested Claim
Corroboration is strongest when an independent source has relevant access to the same fact. Repetition is not automatically confirmation: several pages may copy one unsupported post. Prefer evidence that can be traced to its own observation, record, or method.
Quick Reference
- Verifiable, supported, and true are separate questions.
- Opinions evaluate or recommend and may still use evidence.
- Diagnose bias from wording, selection, incentives, and omissions—not disagreement alone.
