[ 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

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.

Evidence Notes.

8 Findings Published

Evidence

Primary referent: format underlined squiggle.

Evidence

Implied function: The icon must communicate Format Underlined Squiggle in a digital interface..

Evidence

Metaphor type: functional.

Evidence

The icon effectively represents the 'Format Underlined Squiggle' function as a compact symbolic control in digital text editing interfaces, aligning well with provider metadata and expected message.

Evidence

Visual metrics indicate strong perceptual clarity and resilience, with a high overall visual score (0.77) and good performance in size, blur, and contrast robustness, supporting usability across platforms and display conditions.

Evidence

Semantic and functional convergence scores are moderate (0.53 and 0.57 respectively), showing that while the icon generally conveys its intended meaning, some ambiguity remains, especially due to possible confusion with similar text formatting icons or spelling/grammar check indicators.

Evidence

Cultural convergence is low (0.31), reflecting limited widespread recognition and cultural saturation; this is supported by low referent recognition (0.37) and evidence reliability (0.09) scores, indicating sparse public evidence and research on this symbol's comprehension.

Evidence

Temporal convergence (0.57) and neurocognitive convergence (0.59) suggest moderate persistence of meaning over time and reasonable alignment with pictogram reading principles, but the symbol requires a moderate learned convention load (0.4) and carries a notable neurocognitive transfer risk (0.48).
