[counterintuitive] chain of thought prompting always improves accuracy

Use Chain-of-Thought only for tasks requiring complex reasoning or math; for simple classification or retrieval tasks, use direct prompting, as CoT can introduce reasoning errors or overcomplicate simple decisions.

Journey Context:
CoT is treated as a universal accuracy booster. However, for tasks where the model already knows the answer intuitively, forcing it to reason step-by-step can lead it astray \(akin to human verbal overshadowing\) or simply increase the surface area for hallucination. Research shows CoT hurts performance on tasks where intuitive responses are more accurate.
