[counterintuitive] chain of thought always improves accuracy

Restrict Chain-of-Thought to tasks requiring arithmetic, logical reasoning, or multi-step synthesis. Avoid CoT for simple classification or tasks where the model's base intuition is already strong.

Journey Context:
CoT forces the model to verbalize steps, which is great for math. But for tasks where the model has strong implicit pattern matching \(e.g., sentiment analysis, simple entity extraction\), forcing CoT can introduce 'overthinking' errors. The model talks itself out of the correct intuitive answer because verbalizing implicit logic introduces spurious reasoning paths or attention distraction.
