[counterintuitive] chain of thought always improves accuracy

Restrict Chain-of-Thought \(CoT\) prompting to tasks requiring genuine multi-step reasoning or math. For simple classification or factual retrieval, use direct prompting to avoid reasoning-induced errors.

Journey Context:
CoT is often treated as a universal accuracy booster. However, research shows CoT can degrade performance on tasks where models already have strong intuitive \(System 1\) capabilities. Forcing a model to explain its reasoning on simple tasks can cause it to overthink, rationalize incorrect paths, or alter a correct initial intuition to match a flawed generated explanation.
