[counterintuitive] Forcing chain-of-thought reasoning unconditionally improves task accuracy

Restrict chain-of-thought prompting to tasks requiring genuine multi-step reasoning or math. For simple retrieval or classification tasks, use zero-shot direct answering.

Journey Context:
CoT can degrade performance on tasks where the model's intuitive \(direct\) answer is correct, but verbalizing the reasoning introduces logical fallacies or distracts the model. Over-thinking simple tasks leads to higher latency and lower accuracy. CoT is a tool for decomposing complexity, not a universal accuracy booster.
