[counterintuitive] Does chain of thought prompting always improve accuracy

Evaluate CoT on a per-task basis; avoid CoT for tasks requiring fast, intuitive, or strictly memorized responses where deliberation introduces noise or overthinking.

Journey Context:
CoT is widely prescribed as a universal accuracy booster because it allows models to compute intermediate steps. However, for tasks where the model already has strong, direct intuitions \(e.g., simple sentiment analysis, basic arithmetic it has memorized\), forcing CoT can degrade performance. The model may second-guess itself, introduce calculation errors in the intermediate steps, or overcomplicate simple pattern matching.
