Categorization is omnipresent in our thinking and being, and helps us navigate the complexity of human experience. This suggests a collective, universal matrix that determines our relationships with each other and our environment by sorting knowledge, and influencing design. But who or what decides on this supposedly objective structure? Can such a matrix be universal? Or is it informed by patriarchal, colonial, capitalist, and ableist legacies? This work examines the epistemic and social dimensions of categorization and the power structures on which it is based. An examination of design history reveals the close entanglement of design and categorical thinking. An experimental design work emerges from the system-theoretical speculation, which translates values such as diversity, non-linearity, simultaneity, and ambiguity into a design language. A mixed-media poster series challenges design conventions and uncovers the fertile potential offered by Miscellaneous Matter.
