For new services to be successful, users (customers, patients, citizens, etc.) must embrace and sometimes engage in behaviors that are both new and difficult for them. As research has put more and more emphasis on the importance of being user-centric, it is hard to understand why the behavior change that many times are required for the user has not been problematized more. In this chapter we present five evidence-based ways that describe and explain how behavior change can enable important services such as sustainability, education, and health—services make the world a better place.
