[counterintuitive] chain of thought always improves reasoning

Evaluate CoT on a per-task basis. For simple, highly memorized tasks or tasks requiring strict adherence to a rigid format, use direct prompting to avoid introducing unnecessary reasoning steps that lead to errors.

Journey Context:
CoT is widely treated as a universal accuracy booster that forces the model to 'think'. However, for tasks where the model already has strong, direct intuitions, forcing a CoT explanation can introduce logical missteps that override the correct intuitive answer. Additionally, CoT makes the model highly susceptible to irrelevant context in the prompt, degrading performance on straightforward tasks compared to zero-shot direct prompting.
