Note: If you haven’t listened yet, check out the Archispeak podcast for a satirical take on this topic.
Why do landscape architects and architects use philosophical language that even they can’t understand to describe their work?
Why does the description of a chair claim that its form is a response to the conflict in Syria and world hunger?
Why does a site’s design have to be a commentary on the confluence of ecotypes and cultural norms independent of time constraints along the space axis?
Because we want it to be. It puts the user or reviewer into a state in which they want to experience something sophisticated and magical. And, with help from the placebo effect, they do.
This is independent of what is actually happening outside of the viewer’s mind, but is extremely powerful and real. Design could probably use a little more of it (placebo effect, that is, not ego-driven grandstanding).
Just describe your grand visions in more accessible language and with vivid analogies. You get your placebo effect, and it will stick better.
