[counterintuitive] chain of thought always improves accuracy

Evaluate CoT on a per-task basis; avoid CoT for tasks requiring strict adherence to priors or where verbalization degrades implicit pattern recognition.

Journey Context:
CoT is widely prescribed as a universal accuracy booster. However, for tasks where humans perform better without verbalizing \(implicit learning or fast pattern recognition\), CoT can disrupt the model's implicit reasoning. Furthermore, CoT can sometimes amplify biases by generating plausible but incorrect justifications post-hoc, or cause the model to overthink simple instructions and deviate from strict formatting rules.
