[counterintuitive] Does chain of thought prompting always improve accuracy

Evaluate CoT on a per-task basis; avoid CoT for tasks requiring fast, intuitive pattern matching or where verbalizing the reasoning introduces bias or overthinking.

Journey Context:
CoT is treated as a universal accuracy booster. However, for tasks where the model already has strong intuitive capabilities, forcing step-by-step reasoning can cause the model to second-guess itself, introduce logical loops, or rationalize incorrect answers. Research shows CoT can hurt performance on smaller models or simple tasks where zero-shot intuition is more reliable.
