Evidence, sources, and time
How source lineage, freshness, and independence affect what can be supported.
Keep each result linked to its source
- Source and observation coordinates
- Receipt or observation time
- Integrity reference
- Correction, withdrawal, and counter-evidence state
Freshness is inquiry-specific
Old evidence is not automatically false. It may still be insufficient for a question that requires a current state.
Copies are not independent corroboration
Multiple publications derived from the same origin should not be counted as multiple independent sources.
