[gotcha] showing AI reasoning chain-of-thought decreases trust rather than increasing it

Default to hiding reasoning. Only show reasoning on demand or when the user explicitly asks why. When showing reasoning, format it as a concise summary rather than a raw token stream. Test trust metrics with reasoning visible versus hidden before shipping.

Journey Context:
The intuition is that showing the AI's reasoning increases transparency and trust. In practice, it often does the opposite. When users see AI reasoning, they evaluate it against human reasoning patterns. AI reasoning often includes restating the problem in obvious ways, considering and dismissing alternatives for unclear reasons, or making logical leaps that do not match human intuition. This alien reasoning can be more unsettling than no reasoning at all—it is the uncanny valley of AI cognition. Users think: if this is how it reasons, how can I trust the answer? Additionally, showing reasoning reveals the AI's uncertainty and hedging, which users find concerning even though uncertainty is actually a sign of good calibration. Raw chain-of-thought streams are especially problematic: they show the model talking to itself in a way that feels neither human nor machine, landing squarely in the uncanny valley. The fix is to treat reasoning display as an opt-in feature, not a default. When shown, summarize the reasoning into human-legible steps rather than showing the raw stream. Anthropic's extended thinking feature, for example, shows a summarized version of reasoning rather than the full token stream for exactly this reason.
