[counterintuitive] Chain-of-thought reasoning makes LLM outputs more trustworthy

Treat reasoning traces as decoration, not evidence. Verify the final answer independently with tests, citations, or a second model; ask the model to state confidence separately from its reasoning.

Journey Context:
Developers often believe that a step-by-step explanation signals reliability. Research on reasoning budget and calibration shows that generating more tokens can inflate confidence faster than it inflates accuracy: the model becomes confidently wrong. The visible logic also creates an illusion of transparency; humans anchor on a coherent narrative even when the conclusion is wrong. The right model is that CoT is a search/optimization technique, not a guarantee or an audit log.
