Disgust, Shame, and Soapy Water: Tests of Novel Interventions to Promote Safe Water and Hygiene
研究测试了基于厌恶和羞耻情绪的信息对孟加拉国贫民窟居民洗手和饮用水氯化行为的影响，发现传统健康宣传和情绪干预均未显著提高氯化使用率，但低成本洗手设施略有改善。
Lack of access to clean water is among the most pressing environmental problems in developing countries, where diarrheal disease kills nearly 700,000 children per year. While inexpensive and effective practices such as chlorination and hand washing with soap exist, efforts to motivate their use by emphasizing health benefits have seen only limited success. This paper measures the effect of messages appealing to negative emotions (disgust at consumption of human feces) and social pressure (shame at being seen consuming human feces) on hand-washing behavior and use of and willingness to pay for water chlorination among residents of slum compounds in Dhaka, Bangladesh. Neither the traditional, health-based message nor the new disgust-and-shame message led to high levels of chlorination during a free trial, nor to high willingness to pay for the chlorine at the end of the free trial. Provision of low-cost hand-washing facilities did increase hand washing, although the effect size is modest.
