The corroboration vs. repetition distinction.

Five sources saying the same thing does not verify a claim if all five are citing the same original source. True corroboration requires multiple independent sources reaching the same conclusion through independent investigation.

Perplexity makes it possible to check source independence: do the citations link to different organizations, different methodologies, different time periods?

The claim verification search.

"Verify this claim: [specific claim]. Search for multiple independent sources that either confirm or contradict it. For each source: (1) What does it specifically say? (2) Is it independent of the other sources (different organization, different methodology)? (3) Is this the most current information available?"

Reading for contradiction.

Verification is not just looking for confirmation. Perplexity should be asked to look for contradictory evidence too:

"Search specifically for research, evidence, or authoritative sources that challenge this claim: [claim]. What do the best counterarguments or contradicting sources say?"

If the claim holds up against challenge research, it is more credible than if it was only confirmed.

The source independence check.

When evaluating whether sources are truly independent, ask:

• Did they conduct independent research, or are they reporting on the same underlying study?
• Do they have different methodologies (survey vs. experimental vs. observational)?
• Are they from different organizational perspectives (government vs. industry vs. academic)?
• Are they from different time periods, or all citing the same period?

Verification confidence levels.

After research:

• High confidence: Multiple independent, authoritative sources with different methodologies and perspectives reach the same conclusion, and challenge research did not find significant contradictions
• Moderate confidence: Several sources agree, but they share some methodological or organizational overlap
• Low confidence: Sources all cite the same original, or the claim is in a rapidly evolving area where newer research might differ
• Unverified: Could not find authoritative independent confirmation – qualify or remove
