[counterintuitive] Chain-of-thought gives a plausible rationale that does not actually explain the answer

Treat CoT as a heuristic explanation, not an audit trail. For safety-critical reasoning, verify outputs independently with code, formal checks, or external solvers instead of trusting the rationale.

Journey Context:
CoT is widely used as a transparency mechanism: if the model explains itself, we can catch errors. Research shows generated rationales can be post-hoc confabulations that do not determine the answer. The model may select an answer early and then produce a convincing story. Better prompts cannot guarantee faithfulness; external verification does.
