[gotcha] Showing AI reasoning steps backfires when steps contain hallucinated logic

Default to hiding chain-of-thought reasoning. If you must show it: \(a\) label it clearly as 'AI reasoning — may contain errors', \(b\) visually de-emphasize it \(collapsed by default, lighter styling\), \(c\) let users flag specific reasoning steps as wrong. For high-stakes domains, never show raw chain-of-thought — summarize reasoning into independently verifiable claims instead.

Journey Context:
The intuition is seductive: showing reasoning builds trust through transparency, just like showing your work in math class. This works when reasoning is correct. But LLM chain-of-thought frequently contains plausible-sounding intermediate steps that are fabricated — the model retrofits reasoning to justify an answer it already decided on. When users spot an error in step 2 of a 5-step chain, they distrust the entire output, even if the final answer happens to be correct. This is strictly worse than not showing reasoning at all, because it actively erodes existing trust rather than simply not building it. The uncanny valley of reasoning: slightly-wrong visible reasoning is more damaging than no visible reasoning.
