Transparency is most useful when it helps a person follow a claim back to something concrete. The interface should make that path understandable rather than hiding it inside a wall of numbers.
State the activity or claim in plain language.
Show the relevant record, observation or learning result.
Add location and time context when it is relevant and appropriate.
Explain the verification step instead of using the word “verified” as decoration.
Make the underlying evidence or an honest limitation visible.
If a screen contains demonstration records, it must be labelled as demo data. If evidence is incomplete, say that. Trust is built by making the boundary between known and unknown easy to see.
The answer should not be another slogan. It should be a record, a context, a limitation, or a clear explanation of what is still unknown.
