[gotcha] Displaying AI chain-of-thought reasoning to users backfires — creates false trust or confusion

Default to hiding raw chain-of-thought. If transparency is required, show a summarized reasoning step such as 'I checked 3 sources and compared dates' rather than the actual CoT tokens. Only expose raw reasoning in debug or developer modes. Never let users conflate 'the AI showed its work' with 'the AI is correct'.

Journey Context:
The intuition is seductive: showing the AI's reasoning builds trust, just like showing math work in school. But in practice, raw CoT has two failure modes. First, users see detailed reasoning and anchor on it — if the AI says 'Let me think step by step...' and produces a confident-sounding chain, users trust the process even when the conclusion is wrong. This is the trust-by-verbosity trap. Second, CoT often contains internal reasoning that is nonsensical or unsettling when surfaced — the AI might consider wrong paths, make strange analogies, or reveal that its reasoning is shallow. The counter-intuitive insight: transparency about process can reduce appropriate trust. Users are better judges of output quality than reasoning quality, because they have domain knowledge about answers but not about how LLMs should think. The right pattern is summarized transparency: tell the user what the AI did at a level they can evaluate, not what the AI thought internally.
