Report #10756

[research] LLM generates plausible but fabricated reasoning steps to justify a hallucinated conclusion

Use Chain-of-Thought \(CoT\) prompting, enforce a 'reasoning before conclusion' structure using strict formatting, and validate intermediate steps programmatically if possible.

Journey Context:
Unconstrained generation allows the model to state an answer and then rationalize it, or to make a logical leap in the middle of a CoT. By forcing the model to output the reasoning first \(e.g., using structured XML tags for steps\) and separating it from the conclusion, you reduce the chance of post-hoc rationalization, though it doesn't eliminate logical leaps entirely.
