[counterintuitive] chain of thought prompting always improves reasoning

Evaluate CoT on a per-task basis. Use direct prompting for tasks requiring fast intuition or where verbalizing reasoning introduces bias; reserve CoT for tasks requiring genuine multi-step computation.

Journey Context:
CoT is treated as a universal accuracy booster. However, for tasks where humans perform better without verbalizing \(e.g., intuitive leaps, simple classifications\), forcing CoT can degrade performance. Worse, CoT can rationalize incorrect answers, making the model more confidently wrong. Research shows CoT isn't strictly necessary for many tasks and can hurt performance on simple ones by over-complicating the reasoning path.
