[T]he privilege of establishing what value the default is set at is an act of power and influence. Defaults are a tool not only for individuals to tame choices, but for systems designers -- those who set the presets -- to steer the system. The architecture of these choices can profoundly shape the culture of that system's use. Even the sequences of defaults and choices make a difference too. Retail merchandisers know this well. They stage stores and websites to channel decisions in a particular order to maximize sales. If you let hungry students make their desert choice first rather than last, this default order has an impact on their nutrition.
