Things that sit near each other are read as belonging together. The Law of Proximity is one of the original Gestalt principles, established by Max Wertheimer in 1923, and it describes how spatial distance is one of the strongest and most automatic cues the brain uses to infer relationships between elements. Proximity works without labels, without connecting lines, and without color. It is purely spatial, and it operates below conscious awareness: people group nearby elements and separate distant ones without ever deciding to.
