Evaluation
Despite expanding access to sanitary options such as community toilets, many individuals, especially in urban slums, continue to practice open defecation. One potential explanation is that open defecation has become an ingrained habit. Applying lessons from psychology and neuroscience, researchers are evaluating whether a combination of economic incentives and a marketing campaign can foster a new habit—using hygienic latrines instead defecating in the open—among slum dwellers in Kenya.
