Change Blindness
The failure to detect changes in a visual scene when the change occurs during a brief interruption, eye movement, or distraction.
Explained
- People routinely miss changes to a screen when their attention is elsewhere during the change.
- A swap that happens across a page load or behind a spinner can go completely unnoticed.
- The eye assumes stability, so it does not re-scan what it believes it already understands.
- This is why silent updates to totals, states, or content often confuse users later.
