[counterintuitive] chain of thought always improves reasoning

Evaluate Chain-of-Thought on a per-task basis; avoid CoT for tasks requiring strict rule adherence or where the model has strong, fast intuitive mappings.

Journey Context:
While CoT is powerful for math and logic, it can degrade performance on simple tasks or those requiring strict adherence to prior rules. CoT can introduce 'overthinking' or rationalization errors, where the model talks itself out of the correct answer. It also increases latency and token usage. For tasks where zero-shot is already highly calibrated, forcing the model to 'think step by step' can actually increase hallucination rates.
