[counterintuitive] does chain-of-thought always improve accuracy

Reserve CoT for complex, multi-step reasoning tasks. For simple classification or retrieval tasks, use direct prompting, as CoT can introduce overthinking and degrade performance.

Journey Context:
Developers treat Chain-of-Thought as a universal accuracy booster. However, CoT forces the model to generate intermediate steps, which can lead it to rationalize a wrong answer \(overthinking\) or change a correct intuitive answer. For tasks where the model already has strong zero-shot intuition \(e.g., simple sentiment analysis\), CoT adds latency and increases the surface area for hallucination or logical missteps.
