[research] Trusting Chain-of-Thought reasoning as proof that the final answer is factually grounded
Treat CoT as a suggestion of reasoning, not a guarantee. If factuality is critical, verify the individual claims in the CoT against an external knowledge base, rather than assuming the CoT proves the final answer is grounded.
Journey Context:
Developers often use CoT to 'show work' and assume that if the steps look logical, the answer is factually grounded. However, models often generate the answer first and then rationalize it \(post-hoc rationalization\), or the CoT ignores provided context in favor of parametric memory \(unfaithfulness\). Trusting CoT gives a false sense of anti-hallucination security.
