[counterintuitive] Chain-of-thought prompting always improves reliability and reduces errors.

Reserve chain-of-thought for problems where reasoning steps are verifiable; always validate the final answer independently, because CoT can produce coherent justifications for wrong answers and amplify sycophancy.

Journey Context:
CoT elicits step-by-step reasoning and can boost performance on structured tasks, but it also gives wrong answers a plausible-looking explanation, making them harder to catch. On adversarial or ambiguous prompts, models can rationalize toward user-preferred conclusions. The right model is: CoT is a reasoning scaffold, not a correctness guarantee. Pair it with execution, unit tests, external checks, or self-consistency sampling, and be especially wary when the task's correctness cannot be mechanically verified.
