[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 reflexive responses where deliberation introduces bias or overthinking.

Journey Context:
CoT is treated as a universal accuracy booster. However, research shows CoT can decrease performance on tasks where models already have strong intuitive capabilities, or where the reasoning steps force the model into a biased path. CoT also makes models highly susceptible to irrelevant context, causing them to reason using wrong premises.
