Here’s a scenario that has totally never happened to me before: you’ve had a long day of classes and you’re ready to finally head home to your apartment in Collegetown, when you find yourself pulling on a push door as you exit, say, Upson Hall. You feel like an idiot; you’re a junior and here you are, looking like a prospective student visiting campus for the first time. But what if I told you that’s not your fault? That, instead, you’ve fallen prey to one of the most common design errors: the Norman door. First coined in the 1988 novel The Design of Everyday Things, the Norman Door is the result of poor and conflicting design decisions that make it difficult to determine how to operate the door, often resulting in a reliance on signage, or allowing its users to feel like idiots every day.
