Orderliness

Orderliness is a personality trit, associated with other qualities such as cleanliness and diligence—and the desire for order and symmetry, and is generally considered to be a desirable quality.

In psychology, an excessive desire for orderliness can be associated with obsessive–compulsive disorder and the term anal retentive, (or simply anal)—from Freudian psychoanalysis—is used conversationally to describe a person with such attention to orderliness and detail that it becomes close to a mental disorder.

Thomas J. Bouchard, Jr. explored the heritability of this trit in his twin studies.
