mangelfullt

Mangelfullt is a term used in critical design and information visualization to describe systems that deliberately withhold or obscure elements of information, thereby inviting user interpretation and active participation. In practice, mangelfullt refers to interfaces, narratives, or data presentations that balance transparency with opacity, creating space for ambiguity and inquiry rather than definitive answers.

Etymology and origins: The word combines roots related to deficiency ("mangel" in several Germanic languages) with a suffix implying completeness or fullness. In contemporary design discourse, mangelfullt emerged in the late 2010s as a descriptor for practices that treat gaps in data or function as a design resource rather than a flaw.

Characteristics: Key features include partial disclosure, open-ended outcomes, user-supplied inputs to complete a system, and a focus on process over finished state. Mangelfullt designs often incorporate ethical considerations regarding user effort, accessibility, and bias, since gaps can affect interpretation and inclusivity.

Applications: The concept appears across software interfaces, interactive installations, and data storytelling. Examples include dashboards that show only a subset of metrics, narratives that require audience contribution to progress, or visualizations that reveal the data collection process only in part to stimulate critical thinking.

Reception and critique: Proponents credit mangelfullt with increasing engagement and critical literacy, while critics warn that excessive opacity may hinder comprehension and accessibility, potentially alienating users with different needs or expertise.
