[counterintuitive] Force the model to use Chain-of-Thought reasoning for every task to maximize accuracy

Use CoT only for complex, multi-step reasoning tasks; for simple retrieval or intuitive tasks, use direct prompting, as CoT can introduce verbosity and reasoning errors.

Journey Context:
CoT is widely touted as an accuracy booster, leading developers to append 'think step by step' to every prompt. However, for tasks where the model has already internalized the mapping \(e.g., simple translation, basic factual retrieval, or implicit statistical learning\), forcing CoT introduces unnecessary tokens where the model can contradict itself, overthink, or introduce logical fallacies. CoT is a tool for decomposing complexity, not a universal accuracy charm; it often hurts performance on simple tasks by increasing the surface area for error.
