[counterintuitive] Does chain of thought prompting always improve accuracy

Evaluate CoT on a per-task basis. Avoid CoT for tasks requiring strict adherence to simple rules or fast, low-latency responses where intuitive 'System 1' responses are already highly accurate.

Journey Context:
CoT is widely prescribed as a universal accuracy booster, but it can degrade performance on tasks where models are already well-trained and the reasoning path introduces opportunities for error or 'overthinking'. It also dramatically increases latency and token usage. For simple tasks, forcing a model to explain itself can lead it astray.
