Social innovations are creative products and changes that are motivated by social needs and bring value to society by meeting those needs. This article uses case studies to investigate the cognitive and social processes that contribute to creativity in social innovation. The cases are: Wendy Kopp with Teach For America in education, Cicely Saunders with hospices in health care, Mark Zuckerberg with Facebook in technology, Elizabeth Fry with prison reform in social movements, Millard Fuller with Habitat for Humanity in organizations, and Muhammad Yunus with microfinance in finance. These cases illustrate the cognitive processes of combination of mental representations, problem solving, emotion, association, analogy, and method generation. They also illustrate the social processes of emotional communication, support, and conflict.
