[counterintuitive] Does chain of thought prompting always improve reasoning accuracy

Evaluate CoT on a per-task basis. Avoid CoT for tasks requiring fast, intuitive, or strictly memorized responses where verbalizing the reasoning introduces noise.

Journey Context:
CoT is treated as a universal accuracy booster. However, for tasks where the model already knows the answer intuitively \(System 1 tasks\), forcing CoT can cause the model to overthink, make errors in the reasoning steps, and then confidently output the wrong answer derived from the flawed step-by-step logic rather than its correct intuition. It also dramatically increases latency and token cost.
