Not surprisingly the whole humanity is afraid of all accidental — removes random elements from automotive design, food, etiquettes, safety rules — because the incident is a danger! Everything left from everchanging nature is traffic, weather, mood, - everything else are organized into rules, rows and routines. Art saves the world, hiding the glances of contemporaries into the chaotic magic of jazz, abstractions, cinema. Why we need randomness? Because it is the state of subconsciousness — the 80% of our poor mind. Src
