[ SCORE SCALE ]
The Public Verdict Has A Range.
The level explains the estimated context. It is not a certification.
0.80-1.00
Strong clarity
The pictogram communicates well in this context.
Use it, then keep testing with real users.
0.65-0.79
Usable with support
Current report
The pictogram works with labels or context.
Pair it with text and monitor interpretation.
0.50-0.64
Needs intervention
The pictogram carries meaningful clarity risk.
Improve the symbol before relying on it.
0.00-0.49
Not reliable
The pictogram does not communicate enough alone.
Replace it or add strong alternative support.
