[gotcha] Showing AI chain-of-thought reasoning to users reduces trust instead of increasing it

Default to hiding reasoning in consumer-facing products. If you must expose it: \(a\) clearly label it as 'draft notes' or 'working notes', not 'explanation'; \(b\) visually separate it from the final answer \(collapsible, different panel\); \(c\) never show raw reasoning in high-stakes domains \(medical, legal, financial\) where flawed justifications for correct answers create liability.

Journey Context:
The intuition is seductive: showing reasoning increases transparency, so it should increase trust. In practice, it often does the opposite. \(1\) Chain-of-thought can contain factual errors even when the final answer is correct—users who spot a reasoning error distrust the entire output. \(2\) LLM reasoning is often post-hoc rationalization, not an actual decision process; showing it creates a false model of how the AI works. \(3\) Raw reasoning can leak system prompt fragments, safety instructions, or embarrassing internal corrections \('wait, that's wrong, let me reconsider'\). \(4\) Verbose reasoning adds cognitive load without actionable value for the user. OpenAI's o1 model hides its chain-of-thought by default, showing only a summarized 'reasoning' section—a deliberate design decision acknowledging these problems. The exception: in developer/debugging contexts, showing reasoning is valuable because the audience can properly contextualize it.
