[counterintuitive] Applying chain-of-thought prompting to all tasks for better accuracy

Reserve CoT for complex, multi-step reasoning tasks; use direct prompting for simple, factual, or intuitive tasks.

Journey Context:
CoT is widely treated as a free lunch for accuracy. However, forcing a model to 'think step by step' on tasks it already knows intuitively increases the surface area for reasoning errors, leading to rationalization of wrong answers or overthinking. Smaller models also struggle to generate valid CoT, often degrading performance compared to zero-shot.
