People may choose healthier foods if they are better able to understand their nutritional contents and may choose lower-calorie meals if they are explicitly asked if they would like to downsize their side orders.
Other examples of nudges include:
- changing which option is the default option to which people will be assigned if they do not expressly make a choice,
- placing a limit on the serving size of soda, or
- automatically enrolling employees in a retirement savings program.
