[counterintuitive] chain of thought prompting always improves accuracy

Restrict CoT to tasks requiring reasoning or arithmetic; for simple retrieval or memorization tasks, use direct prompting to avoid reasoning-induced hallucinations.

Journey Context:
CoT is treated as a universal accuracy booster. However, for tasks where the model already knows the answer intuitively, forcing it to reason step-by-step can lead it down incorrect paths, increasing error rates and latency. CoT trades off direct retrieval accuracy for compositional reasoning accuracy. Think or don't think depending on the task complexity.
