Calibration Transparency Requires Behavioral Guidance
The Principle
Informing users about AI uncertainty characteristics is necessary but insufficient. Users need explicit guidance on how to adjust their behavior, not just awareness of the problem.
Why This Matters
Transparency has become a default recommendation in AI ethics and design: “Tell users what the system is doing.” But research on miscalibrated confidence reveals a gap between awareness and appropriate action.
When users learn their AI collaborator is overconfident, they appropriately reduce reliance. But when they learn it’s underconfident, they also reduce reliance, even though the correct response is to increase it. Users default to “trust it less” as a response to any uncertainty disclosure.
This creates a situation where well-intentioned transparency can worsen outcomes. A designer who faithfully communicates “this model tends to understate its confidence” may inadvertently cause users to ignore good advice.
How to Apply
-
Don’t stop at labeling: Naming the calibration problem doesn’t tell users what to do about it
-
Provide directional guidance: “This model is underconfident, its predictions are usually better than its stated confidence suggests. Consider trusting it more when it seems uncertain.”
-
Design for the behavioral response, not just comprehension: Test whether users actually adjust behavior appropriately, not just whether they understand the label
-
Consider confidence transformation: If possible, recalibrate displayed confidence rather than labeling miscalibration, showing accurate confidence eliminates the need for users to mentally adjust
Exceptions and Limitations
This principle applies most clearly when users must make decisions based on AI advice. In pure information contexts without decision pressure, transparency for its own sake may have value regardless of behavioral outcomes.
The research examined a specific task (city image recognition) with non-expert users. Domain experts who understand calibration concepts might respond differently to transparency labels.
