Unit 1 · Lesson 4 of 20
What makes an experience trustworthy?
Relate clarity, evidence, control, privacy, and reversibility to the stakes of a decision.

The idea
Trustworthy UX lets people form accurate expectations and retain appropriate control. The interface should make the proposed action, recipient, source material, and consequence visible before commitment. A fluent draft or confident tone is not proof that the content is correct or that the user has authority to send it.
The amount of review should reflect possible harm and reversibility. A small formatting change may need light feedback; a message to thousands of customers needs a reviewable payload, permissions, and a recovery plan. Privacy also matters: previewing sensitive information to the wrong role can be harmful even if no message is sent. Record uncertainty honestly and test whether users notice material limitations.
A generic 'Are you sure?' prompt creates informed consent. Confirmation without decision-critical context can increase clicks while leaving understanding unchanged.

Worked example
Fictional scenario
An AI assistant drafts a customer message and offers to send it to an entire account list.
An expert examines a 'Send now' button next to an AI draft. They add a review step showing recipients, the exact outgoing content, source status, and the operator's authority. If a source is outdated, the flow blocks the unsupported claim and offers editing or escalation. The design is judged by whether the human can actually catch a harmful action, not by the presence of a modal.
Try a decision →03 / Decide
Guided decision
The draft cites a superseded policy, but the operator can see the approved current policy. Which flow would you test first?
Feedback on your choice
What could change the answer: If no approved policy can be reached or source errors are systematic, pausing the affected feature becomes more defensible until the source and review path are repaired.
This feedback helps you examine the decision; it does not grade your written reasoning.
Apply it somewhere new →04 / Apply elsewhere
Independent application
Fictional scenario
A shared physical access terminal lets a supervisor revoke a contractor's building access immediately.
Describe the review, authority, confirmation, and reversal or support path for this action. Include what should and should not be displayed on a shared terminal.
Make: A concise risk and control map with an annotated action sequence.
The proposal matches controls to consequence, identifies authority and privacy, and does not treat a generic confirmation as sufficient evidence of understanding.
