The psychology of collecting is an area of study that seeks to understand the motivating factors explaining why people devote time, money, and energy making and maintaining collections. There exist a variety of theories for why collecting behavior occurs, including consumerism, materialism, neurobiology and psychoanalytic theory. The psychology of collecting also offers insight into variance between similar behavior that can be recognised on a continuum between being beneficial as a hobby and also capable of being a mental disorder.[1] The large diversity of different types of collected objects and variance of collecting behaviors across these types has also been subject to research in psychology, marketing and game design.[2][3]
Collecting is known to be a common behavior, with one estimate suggests that 40% of United States households engage in some form of collecting behavior,[4] with another source suggesting a global estimate closer to 30% assuming low variance between countries.[5]
