A social norms approach is cyclical in nature; it is a marathon rather than a sprint. A successful social norms project builds momentum through repetition and time. In other words, running a social norms campaign one year and switching to a different tactic the next will generally fail to show results. The social norms approach requires diligence and perpetual motion. The lifecycle of a social norms approach consists of several distinct stages: Formative evaluation, surveying, intervention, and summative evaluation, which will ultimately feed back into the campaign fueling future efforts.
