Report #12496
[research] Agent generates a plausible-sounding but fabricated explanation to justify a hallucinated fact or incorrect code output
Separate the generation of the answer from the generation of the reasoning. Use a 'Critic' agent to independently verify the reasoning steps against the generated output, looking for logical leaps or unsupported claims.
Journey Context:
LLMs are next-token predictors and will happily generate a coherent narrative to justify a false premise \(a form of motivated reasoning\). If the model hallucinates a non-existent function in code, it will invent a library that contains it. Self-correction within the same context window often just reinforces the hallucination. A separate, isolated Critic agent with a different system prompt \(e.g., 'Find the flaw in this reasoning'\) breaks the rationalization loop.
