A choice architect has the responsibility for organizing the context in which people make decisions. [T]here are many parallels between choice architecture and more traditional forms of architecture. A crucial parallel is that there is no such thing as a “neutral” design. [A]s good architects know, seemingly arbitrary decisions, such as where to locate the bathrooms, will have subtle influences on how the people who use the building interact. [S]mall and apparently insignificant details can have major impacts on people’s behavior. [I]n many cases, the power of these small details comes from focusing the attention of users in a particular direction. Good architects realize that although they can’t build the perfect building, they can make some design choices that will have beneficial effects. And just as a building architect must eventually build some particular building, a choice architect must [for example] choose a particular arrangement of food options at lunch, and by so doing she can influence what people eat. She can nudge.
