This field study demonstrates that prompts reduce food waste in a restaurant. Based on the behavioral change literature, it was hypothesized that (1) informational prompts encourage consumers to reduce food waste, and that (2) an informational prompt with a normative message is more effective than a prompt with only an informative message. The results were mixed. As expected, diners who were exposed to prompts asked to take away their leftovers more frequently than diners who were exposed to no prompts. However, prompts with an informative and normative message were no more powerful than prompts with only an informative message.
这项实地研究表明，提示可以减少餐厅的食物浪费。基于行为改变文献，我们假设（1）信息提示鼓励消费者减少食物浪费，并且（2）带有规范性信息的提示比仅具有信息性信息的提示更有效。结果喜忧参半。正如预期的那样，与没有提示的用餐者相比，接受提示要求带走剩菜的用餐者更频繁。然而，带有信息性和规范性信息的提示并不比仅具有信息性信息的提示更有效。
