[counterintuitive] chain of thought always improves accuracy

Restrict CoT to tasks requiring complex reasoning or arithmetic; use direct prompting for simple retrieval or classification tasks where CoT introduces reasoning noise.

Journey Context:
Chain-of-thought prompting is treated as a universal accuracy booster. However, for tasks where the model already knows the answer intuitively \(System 1 tasks\), forcing a step-by-step rationale \(System 2\) can cause the model to second-guess itself, overthink, or introduce logical errors it wouldn't have made with a direct answer. CoT is a tool for eliciting reasoning, not a general-purpose accuracy dial.
