How to run it
Set up properly
Be clear on which icons you are testing and what each is meant to communicate. Test both with and without labels, since they answer different questions.
Include icons you consider obvious. Those are the ones that fail, because nobody thought to check them.
Run the method
Icon guideComprehension TestingAssessing whether users understand content, messaging, or functionality as intended so meaning is clear and actionable.Open guide checks whether icons communicate what they are meant to. Very few do on their own, and the ones people assume are universal frequently are not.
- Present icons both with and without labels, in separate rounds so the label cannot teach the icon.
- Ask people to explain the meaning or the expected action in their own words.
- Observe hesitation, errors and misinterpretation, including confident wrong answers.
- Capture qualitative glossaryFeedbackFeedback is the system response that informs users about the result of their actions.

- Iterate on the icons that failed, and retest rather than assuming the replacement is better.

It is the outcome that matters, and it can fail even when the text is short, clear, and well presented.Open glossary term rather than recognition. After testing, document:
- Icons consistently understood, and consistently not
- Common misinterpretations, which often suggest the better icon
- Whether labels were doing all the work
- Icons needing replacement or a permanent label
Use this before committing to an icon set, and on anything carrying a destructive or irreversible action.
Key takeaway
Use this to make navigation and interactions seamless.
