Hierarchy
n. the willful ranking of variables.
Lidwell, Holden, and Butler present a version of hierarchy for design that only considers the information organizing perspective. Hierarchy in Corporeal Design is far more ubiquitous and powerful than just the choice to utilize menus in a web page. Hierarchy is the basis of free will. The empowered citizen can arrange their priorities to their values. The intentional actor can design their own unique interaction where the lemming actor is forced to follow mindlessly. Hierarchy preexists experience. One can choose personal levels of attention in advance, or if not, a designer may choose these for them.
