アリゾナ大学の研究チームは、人が物を集める行動の根底には「構造や秩序を求める心理」があることを明らかにした(Journal of Consumer Research掲載)。6つの実験を通じて、収集は単なる趣味ではなく、不安定な状況で安心感やコントロール感を得る手段であると示された。例としてパンデミック期のコレクター商品の需要増や、ゲーム『原神』でキャラクターセットが「ほぼ揃っている」状態で収集意欲が急増する現象が挙げられる。研究では「コントロール欲求」が強い人ほど収集意欲が高まることも確認され、未完成のセットが購買を強く動機づけることがわかった。企業にとっては収集性を持たせた商品設計が有効だが、消費者にとっては過剰支出につながるリスクもあると指摘される。

From vinyl albums to items in video games, humans love to collect. But what we really crave is order during chaotic times, says Eller College of Management’s Martin Reimann.

Abstract

Across six studies, we provide converging and robust lab and field evidence that the fundamental human desire for control motivates consumer engagement in collecting, defined as the act of acquiring items that belong to an existing collection. This is because consumers who desire control seek structure, which is created when interconnected components form a holistic entity. A collection can provide such a structure, as it comprises related items that together create a whole set. Hence, as consumers add items to a collection, they are also manifesting a structure. Indeed, we demonstrate that desire for control’s motivating effect on engagement diminishes when structure-seeking is hindered or when the collection is far from completion. This work contributes to extant consumer research by identifying desire for control as a fundamental motivation of collecting behavior, explaining when and why consumers work toward completing their collections, and explicating the structured nature of collecting. Of practical relevance, we provide implications for the enhancement of consumer well-being; the design, positioning, and communication of collectible products; and the creation of policies regulating the collectibles market.
