[counterintuitive] Chain-of-thought always improves reasoning accuracy

A/B test CoT against direct answers for your task. When you use CoT, verify the reasoning chain against the final answer rather than treating verbosity as evidence of correctness.

Journey Context:
CoT helps on multi-step symbolic tasks, but it is not free. It can increase sycophancy, overconfidence, and confabulated intermediate steps that contradict the model's actual processing. On simple intuitive questions, forcing step-by-step reasoning can degrade accuracy. Treat CoT as a hypothesis to validate, not a universal upgrade.
