[counterintuitive] chain-of-thought always improves accuracy

Apply chain-of-thought only for tasks requiring complex reasoning or math; use direct prompting for simple factual retrieval or intuitive tasks to avoid 'overthinking' and logical tangents.

Journey Context:
The 'think step by step' paradigm led developers to append CoT to every prompt. For simple tasks, forcing a model to verbalize reasoning often degrades accuracy. The model can talk itself out of the correct answer, introduce logical fallacies during the verbalization, or get distracted by its own generated context. CoT is a crutch for reasoning, not a universal accuracy booster.
