[counterintuitive] Chain-of-thought prompting always improves reasoning accuracy

Evaluate CoT on a per-task basis; avoid CoT for tasks requiring fast, intuitive, or strictly memorized responses where verbalization degrades performance.

Journey Context:
CoT is treated as a universal accuracy booster. However, for tasks that rely on implicit pattern recognition or rapid retrieval \(e.g., simple classification, identifying known anomalies\), forcing a step-by-step explanation can disrupt the model's direct access to its learned representations, a phenomenon analogous to 'verbal overshadowing' in human psychology. CoT also increases latency and token cost.
