A headline score is a starting point. The explanation should tell you whether that starting point is relevant to your decision.
Two people can look at the same building and ask different questions. One is deciding where to live. Another is evaluating an ownership case. A useful standard needs a shared evidence base and room for both perspectives.
Ask what supports the conclusion.
A reason card should identify a specific quality or concern. “Good location” is too broad. A clear description of access, recurring costs or a condition that needs checking gives the reader something to investigate.
The evidence label matters just as much as the statement. Was the information verified in a document, observed in context or estimated from a proxy? A model output should not borrow the authority of a checked fact.
Look for the watchpoints.
An explanation that contains only advantages is not much of a decision tool. The things that hold an assessment back may be the things that change a buyer’s mind.
That is why the NUVAREL approach includes visible risks and uncertainty. A strong first impression should not push a serious reliability concern out of view.
Check the context of the comparison.
A building is not an individual apartment. An investor lens is not a resident lens. An old assessment may not describe current conditions. Entity, lens, evidence date and methodology version all belong in a responsible comparison.
Precision in the display should never suggest certainty that the evidence cannot support.
A score should leave you with better questions.
The goal is not to remove your judgement. It is to give it a clearer structure: what is supported, what is uncertain, what matters to you and what to verify next.
That is the role we intend reason cards to play in NUVAREL. The number makes a comparison concise. The reasons make it usable.
