The designed environment is social and can create opportunities for people to explore and expand ideas together. When used in a self-guided manor, well-designed environments motivate the solo explorer to share their experience with others.
A 2011 study found that people were more likely to share content with others when it was paired with a physiological sensation When study participants absorbed content while running on a treadmill, they were more likely to share the information than when they received it standing still. By nature, exhibits and environments encourage people to interact using multiple senses and to absorb content in novel ways--leading to more sharing during and after the exhibit expereince.
