[counterintuitive] always use chain of thought prompting for higher accuracy

Evaluate CoT on a per-task basis. Avoid CoT for tasks requiring strict adherence to prior rules, intuitive/fast processing, or where the model already has strong zero-shot capabilities.

Journey Context:
CoT is treated as a universal accuracy booster. However, research shows CoT can degrade performance on tasks where models already have strong intuitive \(System 1\) capabilities, or where the verbalized reasoning steps introduce 'derailment' \(the model follows a flawed logical path confidently\). CoT also makes models more susceptible to irrelevant context. If a task doesn't require multi-step logic, the intermediate steps just add latency and opportunities for error.
