Preference for Disorder
Preference for disorder is not the same as living in a mess. Rather, it means a preference for asymmetry—things that are not necessarily lined up in straight columns. If everything is laid out in straight lines, form is highly predictable. This consistency of pattern tells us where the next addition will be made.
Our brains ultimately get bored with repetition. Part of this capacity also includes feeling comfortable in a tenuous, changing universe, one not quite so sane or orderly. Something that is more unpredictable is inherently more interesting to the brain, perhaps because it is more dangerous and therefore more exciting. The ability to surprise with beauty, insight, or humor is also a part of preference for disorder.
