[counterintuitive] Does chain of thought prompting always improve reasoning accuracy

Evaluate chain-of-thought on a per-task basis; for simple tasks or tasks requiring intuitive responses, use direct prompting, as CoT can introduce reasoning errors that degrade performance.

Journey Context:
Chain-of-thought \(CoT\) is treated as a universal accuracy booster. However, research shows CoT can hurt performance on tasks where models already have strong intuitive abilities or where the verbalized reasoning steps introduce logical fallacies that lead the model astray. 'Think step by step' adds latency and can cause the model to rationalize incorrect paths.
