Progressive disclosure

Progressive disclosure sequences information across multiple screens to prevent cognitive overload by showing only necessary data at any given moment.

This interaction design pattern prioritizes the user's immediate task by hiding advanced or rarely used features (like 'Advanced Settings' menus or truncated 'Read More' text) until specifically requested. By deferring secondary content, interfaces reduce the initial interaction cost and help users maintain focus on primary workflows. Industry leaders like Apple and Google utilize this to manage complexity in mobile environments, ensuring that 80 percent of users get a streamlined experience while the remaining 20 percent can still access deep functionality via icons or disclosure triangles.
