 The initial examples above served as the focus of much of the early literature. The early critics attempted to distinguish interventions such as Cafeteria from interventions such as merely providing information. It is clear from more recent writings that the category of nudges is intended to be quite broad. According to Sunstein all the following are nudges: reminders, warnings, a GPS, disclosure of the interest rate of a bank card, any information about what people like you do, simplification of government forms, default rules, subliminal messages urging people to eat healthy food.
