[synthesis] Why displaying AI confidence scores reduces trust instead of increasing it

Replace probability-oriented confidence displays \('90% confident'\) with action-oriented confidence \('I can definitely do X, I'm uncertain about Y, I cannot do Z'\). Design UIs that let users act on confidence—auto-execute, confirm-before-executing, suggest-alternatives—rather than merely observe a number.

Journey Context:
The intuition is that showing confidence scores helps users calibrate trust. In practice it often reduces trust because users and models interpret confidence on fundamentally different scales. A model's '90% confident' means 'in 9 out of 10 similar training-distribution cases, the output was near-correct.' Users interpret it as 'this answer is 90% likely to be right for my specific situation right now.' These are different statements—the former is about the training distribution, the latter about the user's current context. When the model is wrong despite high confidence \(which happens routinely due to distribution shift\), users feel betrayed at a deeper level than if no confidence had been shown. The fix is to translate confidence into action affordances: high confidence → autonomous execution, medium confidence → execute with confirmation, low confidence → suggest alternatives or hand off. This makes confidence actionable rather than informational, and avoids the calibration-mismatch problem entirely.
