[counterintuitive] chain of thought always improves reasoning accuracy

Evaluate CoT on a per-task basis. Avoid CoT for tasks requiring strict adherence to rules or memorized sequences where verbalizing reasoning introduces interference.

Journey Context:
CoT is treated as a universal accuracy booster. However, for simple tasks, it increases latency and cost without accuracy gains. For tasks requiring rigid rule-following or implicit/memorized skills \(e.g., recognizing toxic content, simple classifications\), forcing a step-by-step explanation can actually degrade performance because the model rationalizes a wrong answer \(post-hoc rationalization\) or loses track of the rigid rule in the verbose explanation.
