[counterintuitive] chain of thought always improves reasoning

Restrict Chain-of-Thought \(CoT\) to tasks requiring genuine multi-step reasoning or compositional logic. For simple classification or retrieval tasks, use zero-shot direct answering to avoid 'over-thinking' which introduces reasoning errors and latency.

Journey Context:
CoT is treated as a universal accuracy booster. However, for tasks the model already knows implicitly \(simple classification\), forcing it to explain its reasoning introduces a chance for it to talk itself out of the correct answer, or hallucinate a rationale that leads to the wrong conclusion. CoT trades off latency and token cost for reasoning depth, which is counterproductive for trivial tasks.
