[counterintuitive] chain of thought prompting always improves accuracy

Restrict Chain-of-Thought prompting to tasks requiring genuine multi-step reasoning; use direct prompting for simple tasks or tasks where the model has already memorized the mapping.

Journey Context:
CoT is widely treated as a universal accuracy booster. However, forcing a model to think step-by-step on simple tasks or tasks relying on intuitive pattern matching can degrade performance. CoT can force the model down a path of logical errors it wouldn't have made with a direct answer, or disrupt memorized mappings. CoT is a tool for computation extension, not a general-purpose accuracy enhancer.
