Evidence Notes.
8 Findings Published
Evidence
Primary referent: arrow shape up stack 2 numeric.
Evidence
Implied function: The icon must communicate Arrow Shape Up Stack 2 in a digital interface..
Evidence
Metaphor type: functional.
Evidence
The icon effectively represents the concept of 'Arrow Shape Up Stack 2' as a functional UI action symbol, indicating upward movement or elevation in a layered hierarchy.
Evidence
Visual metrics indicate strong perceptual clarity and robustness, with a perceptual convergence score of 0.75, showing the icon maintains form under size, blur, and contrast variations.
Evidence
Semantic and functional convergence scores (0.58 and 0.61 respectively) suggest the icon generally maps well to its intended meaning and function but with moderate ambiguity potential.
Evidence
Cultural convergence is the weakest axis at 0.53, indicating moderate cultural recognition and some risk of misinterpretation across diverse user groups.
Evidence
Temporal convergence score of 0.53 and a semantic obsolescence score of 0.34 suggest the icon's meaning is moderately stable over time but may require reinforcement through context or labels.

[ RECOMMENDED NEXT ACTIONS ]
What Improves This Pictogram.
Action
Conduct representative user testing across diverse user groups to validate semantic transparency and functional clarity before publication.
Action
Maintain visible text labels or tooltips alongside the icon until user testing confirms that the icon alone reliably communicates its intended meaning.
Action
Enhance contextual cues in the interface, such as placement and grouping, to reduce confusion with similar icons representing upload, sorting, or single upward arrows.
Action
Consider accessibility adaptations to support users with different cognitive styles, ensuring the icon's meaning is clear and transferable.
Action
Monitor cultural recognition trends and update icon design or usage guidelines accordingly to maintain relevance and reduce semantic obsolescence risk.
