Must simplicity and complexity be complete opposites?
As a criterion of classification, simplicity can be described as “well-structured,” complexity as poorly structured. Hence, complex forms can be well-structured and therefore simple, but also poorly structured and therefore complex. Donald Judd, the master of Minimalism, put his finger on it by saying that complicated, incidentally, is the opposite of simple, not complex, which both may be.
(Markus Frenzl, 2009; Donald Judd, Möbel Furniture, Zürich, 1986)
Simplicity therefore complements complexity, rather than competing against it.
Simplicity can also be understood as condensed information instead of filtered information. It makes complexity understandable instead of eliminating it.
Abusive simplification can also obfuscate information, just as deceiving interfaces do.
