[counterintuitive] Chain-of-Thought \(CoT\) prompting always improves model accuracy

Evaluate CoT vs. standard prompting on a per-task basis; avoid CoT for simple, intuitive tasks or tasks requiring strict adherence to formatting without explanation.

Journey Context:
CoT is widely treated as a universal accuracy booster. However, research shows CoT can degrade performance on tasks where models already have strong intuitive capabilities, or where verbalizing reasoning introduces unfaithful rationalizations. CoT trades computation for reasoning, but if the reasoning path is flawed or unnecessary, it amplifies errors and increases latency/costs.
