# Independent verification


## Definition

Independent verification checks an outcome using evidence, components, context, or authority meaningfully separated from the system that produced it. The separation reduces the chance that the producer and verifier share the same hidden mistake.

Independence has several dimensions. A verifier may use a different model but the same prompt and evidence, or a different organization but the same benchmark contamination. Strong designs identify which failure needs separation, then choose an appropriate independent path such as a compiler, production metric, second data source, different toolchain, or accountable human review.

Independence reduces correlated error; it does not make the verifier correct. The verifying method still needs calibration, coverage, and a response for disagreement.

## Distinguish it from nearby terms

Self-critique reuses the producer and often its context. Cross-checking adds another check but may still share the same failure source. Independent verification deliberately separates the evidence or mechanism relevant to the risk.

## Check your understanding

Two agents using the same model inspect the same generated summary and agree on a citation. A direct check of the primary source is more independent than their agreement because it changes the evidence path.
