[counterintuitive] always use chain of thought prompting for better reasoning

Use Chain-of-Thought \(CoT\) only for tasks requiring genuine multi-step reasoning; for simple retrieval or single-step tasks, CoT increases latency and introduces hallucination or overthinking errors.

Journey Context:
CoT is a powerful tool for math and logic, leading to the belief that 'thinking step by step' always helps. However, forcing an LLM to articulate reasoning for a simple factual question or single-step classification gives it more tokens to diverge, hallucinate, or overcomplicate the answer. Research shows CoT can decrease accuracy on simple tasks compared to zero-shot direct answering.
