Pelkistys

Pelkistys (Finnish: "simplification" or "reduction") is the process of removing nonessential elements from a concept, object, representation or system to emphasize core features. It is used across disciplines to improve clarity, usability, aesthetics or analytical tractability by concentrating on fundamental components and relationships.

In visual arts and design, pelkistys appears as minimalism and abstraction: forms are stripped to basic shapes, colors and textures to convey ideas more directly. In architecture and industrial design, it promotes functional clarity, material honesty and efficient use of space. In graphic and interface design, pelkistys reduces cognitive load by eliminating clutter and prioritizing hierarchy and affordance.

In scientific modeling and problem-solving, pelkistys involves creating simplified models that capture essential dynamics while ignoring peripheral factors. This enables analysis, prediction and communication but relies on explicit assumptions about what is negligible. In language, pedagogy and communication, pelkistys helps explain complex topics by focusing on core principles, often using metaphors or analogies.

Benefits of pelkistys include increased legibility, faster comprehension, improved performance and aesthetic coherence. Common criticisms center on the risk of oversimplification: important nuances, context or interactions can be lost, leading to misleading conclusions or reduced functionality. Effective pelkistys balances reduction with fidelity to purpose, making clear which elements have been omitted and why. Related concepts include reductionism, abstraction and minimalism.
