Good questions start with good evidence.

What qualifies as evidence

We prefer primary documents, official statistical datasets, election authorities, manifestos, and international legal texts. Independent reporting can supply context and corroboration. A link is not a verification badge: inspect who produced the information, what it actually supports, when it was published, and which uncertainties remain.

Claims, interpretation, and disputed information

The tools distinguish objective answers from educational interpretations and hypothetical scenarios. Political policy summaries are normalized for comparison and must be read beside their linked evidence. A public statement establishes what was said; it does not prove delivery or accuracy. Unknown evidence is represented as unknown, not converted into agreement.

Review dates and corrections

Question explanations and conflict briefs show their review or as-of dates. A historical dataset stays labeled historical. Evidence can become stale; a dated snapshot should not be treated as a live update. To report a correction, include the question or briefing title, the disputed claim, and a reliable source. Unverified legacy demo claims and invented attributions are not part of these tools.

Primary starting points

These organizations provide useful source material. Individual questions and briefings link the specific evidence used for their claims.
