Definitionv1
Progressive disclosure: the information architecture
Progressive disclosure: the information architecture principle that structures content in layers where each level provides sufficient context to decide whether to drill deeper, ensuring that overview is presented first and detail is available on demand rather than forcing users to consume everything at once
Why This Is a Definition
This definition clearly establishes progressive disclosure as a specific architectural principle with precise operational characteristics. It names the term, identifies its genus (information architecture principle), and states its differentia (layers with sufficient context for decision-making, overview first, detail on demand). It distinguishes this from mere hiding or structuring for author convenience, making it precise enough to avoid confusion with related concepts.
