[counterintuitive] Should I always use chain of thought prompting

Only use Chain-of-Thought for tasks requiring complex, multi-step reasoning. For simple classification, extraction, or tasks the model has already mastered intuitively, use zero-shot or direct prompting.

Journey Context:
CoT is widely treated as a universal accuracy booster. However, forcing a model to verbalize reasoning for tasks it can already do intuitively \(System 1 tasks\) often introduces 'overthinking' errors. The model may second-guess correct snap judgments or introduce logical flaws during the unnecessary step-by-step generation. This not only degrades accuracy but drastically increases latency and token costs. CoT is a tool for extending computational depth, not a blanket best practice.
