[counterintuitive] Chain-of-thought prompting always improves accuracy

Evaluate CoT on a per-task basis; use direct prompting for simple, intuitive tasks or tasks where the reasoning path is likely to mislead the model.

Journey Context:
CoT is treated as a universal accuracy booster. However, for tasks where the model already has strong, direct intuitions, forcing a step-by-step reasoning path can introduce errors or lead the model down a flawed logical path that overrides the correct intuitive answer. CoT is only reliably beneficial for complex, multi-step reasoning tasks like math or coding, and can degrade performance on simple classification or retrieval tasks.
