[counterintuitive] chain of thought prompting always improves reasoning accuracy

Evaluate CoT on a per-task basis; for simple or highly memorized tasks, use direct prompting to avoid unnecessary latency and potential rationalization errors.

Journey Context:
CoT is often treated as a universal accuracy booster. However, for tasks where the model already knows the answer intuitively \(System 1 tasks\), forcing a step-by-step reasoning path can introduce errors or lead the model down a wrong path that it then rationalizes to a wrong conclusion. CoT is only reliably beneficial when the task genuinely requires multi-step computation or logic \(System 2 tasks\).
