[counterintuitive] chain of thought always improves accuracy

Restrict Chain-of-Thought \(CoT\) prompting to tasks requiring logical deduction, math, or multi-step reasoning. For simple retrieval or classification tasks, use direct prompting.

Journey Context:
CoT is often treated as a universal accuracy booster. However, for tasks where the model already knows the answer intuitively \(e.g., simple classification or entity extraction\), forcing CoT introduces unnecessary intermediate steps. This gives the model an opportunity to make a logical error or 'talk itself out of' the correct answer, degrading overall accuracy compared to zero-shot direct prompting.
