[counterintuitive] Forcing Chain-of-Thought reasoning always yields more accurate results

Evaluate CoT vs direct generation per task. Use CoT for complex multi-step logic, but avoid it for simple factual retrieval where direct mapping is sufficient, as CoT can introduce overthinking errors.

Journey Context:
CoT is treated as a universal accuracy booster. However, forcing a model to explain its reasoning step-by-step for simple tasks can cause it to second-guess correct snap judgments, leading to logical detours or sycophantic reasoning where the CoT rationalizes a wrong answer. Research shows unguided CoT and self-correction loops without external feedback can degrade performance compared to direct answering.
