[counterintuitive] Chain-of-thought prompting always improves reasoning accuracy

Evaluate CoT vs. zero-shot on your specific task. Avoid CoT for simple, intuitive tasks or tasks requiring strict adherence to formatting without explanation, as it can degrade performance.

Journey Context:
CoT is celebrated for math and logic, but forcing a model to explain its reasoning can lead it down a path of rationalizing an incorrect answer \(self-delusion\). For tasks the model already knows intuitively, CoT introduces unnecessary tokens, increasing latency and the chance of diverging from the correct path. Zero-shot often outperforms CoT on straightforward classification or extraction.
