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

Evaluate CoT vs direct prompting on a per-task basis; avoid CoT for intuitive or highly memorized tasks where it can introduce reasoning errors.

Journey Context:
CoT is widely adopted as a default for improving reasoning. However, forcing a model to explain its reasoning step-by-step can actually degrade performance on tasks it has already internalized, or when the required reasoning steps are so simple that the generation process introduces unrecoverable errors. CoT is a tool for eliciting latent reasoning, not a universal accuracy booster. It can also increase latency and token usage unnecessarily.
