[ 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

The pictogram works with labels or context.

Pair it with text and monitor interpretation.

0.50-0.64

Needs intervention

Current report

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.

[ CONVERGENCE PROFILE ]

Where Meaning Converges.

The profile compares visual evidence, semantic extraction, cultural recognition, time, and cognitive context. It describes estimated convergence, not universal validity.

Convergent meaning profile

The radar shows where meaning converges. It does not certify universal validity.

[ RECOMMENDED NEXT ACTIONS ]

What Improves This Pictogram.

Action

Run representative user testing before publication.

Action

Keep the text label visible until semantic transparency is proven.

Action

Keep visible label support when scores sit below strong clarity.

Action

Validate interpretation with representative users before high-risk release.

[ Private testing / Admin invite ]

Request an invite for pictogram clarity screening.

Access stays invite-only during private testing.

Requests feed the admin invite queue.

Useful context helps select early pilots.
