The information architecture of a digital space is more than its navigation structure or site map, it is the system’s truth. When we “do” the information architecture we are understanding and shaping that truth, and then communicating it to our users. But architectures are not neutral; the decisions we make shape the larger world. How we understand our work depends on our understanding of how truth and meaning operate in a larger context. Learn what the fields of philosophy, psychology, and physical architecture have to teach us, and how can we start to think about whether the solutions we are architecting are good, not just because they are easy to use, or meet client specifications, but because they actively resist harmful structures, and support beneficial ones.
