The document discusses behavioral design theory and provides examples of how it has been applied to influence behaviors and choices. Behavioral design theory recognizes that human behavior is influenced by both reflective and automatic thought processes, and that people are not always rational. A few applications are described, including using identifiers like color and shape to nudge drivers to park in the correct commuter, staff, or resident spots in a parking lot. The goal is to apply insights from behavioral science to gently influence behaviors.
