Choice architecture describes the way in which decisions are influenced by how the choices are presented. People can be "nudged" by arranging the choice architecture in a certain way without taking away the individual's freedom of choice. A simple example of a nudge would be placing healthy foods in a school cafeteria at eye level while putting less-healthy junk food in harder-to-reach places. Individuals are not actually prevented from eating whatever they want, but arranging the food choices that way causes people to eat less junk food and more healthy food.Sunstein and Thaler, p. 1.
