Which statement best describes corroboration in PI investigations?

• A. Rely on rumors
• B. Use independent, admissible evidence
• C. Depend solely on client statements
• D. Avoid corroboration

Answer: (B)

Corroboration means confirming information by gathering independent, admissible evidence rather than taking a single source at face value. In PI work this is crucial because it strengthens credibility and resilience against challenge by showing that the claim is supported by information from separate, reliable sources and through evidence that could be presented in court.

The statement that best describes this idea is the one that emphasizes independent, admissible evidence. It captures both the need for independent verification and the importance of using evidence that would be allowed in legal proceedings, not hearsay or unverified claims.

Relying on rumors or depending solely on client statements lacks the necessary independent verification. Avoiding corroboration leaves you with information that’s not tested or shareable in a formal setting, which weakens the investigation’s reliability.
