Attention economics is an approach to the management of information that treats human attention as a scarce commodity, and applies economic theory to solve various information management problems. Put simply by Matthew Crawford, "Attention is a resource—a person has only so much of it." In this perspective Thomas H. Davenport and J. C. Beck define the concept of attention as: Attention is focused mental engagement on a particular item of information. Items come into our awareness, we attend to a particular item, and then we decide whether to act. As content has grown increasingly abundant and immediately available, attention becomes the limiting factor in the consumption of information. A number of software applications either explicitly or implicitly take attention economy into consideration in their user interface design, based on the realization that if it takes the user too long to locate something, they will find it through another application. This is done, for instance, by creating filters to make sure the first content a viewer sees is relevant, of interest, or with the approval of demographics. ==History== Herbert A. Simon was perhaps the first person to articulate the concept of attention economics when he wrote: "...in an information-rich world, the wealth of information means a dearth of something else: a scarcity of whatever it is that information consumes. What information consumes is rather obvious: it consumes the attention of its recipients. Hence a wealth of information creates a poverty of attention and a need to allocate that attention efficiently among the overabundance of information sources that might consume it" . He noted that many designers of information systems incorrectly represented their design problem as information scarcity rather than attention scarcity, and as a result they built systems that excelled at providing more and more information to people, when what was really needed were systems that excelled at filtering out unimportant or irrelevant information . In recent years, Simon's characterization of the problem of information overload as an economic one has become more popular. Business strategists such as Thomas H. Davenport or Michael H. Goldhaber have adopted the term "attention economy" . Some writers have even speculated that "attention transactions" will replace financial transactions as the focus of our economic system (Goldhaber 1997, Franck 1999). Information systems researchers have also adopted the idea, and are beginning to investigate mechanism designs which build on the idea of creating property rights in attention (see Applications). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Attention economy」の詳細全文を読む スポンサード リンク
