Second, the differing conceptualizations of the role of game-changers in transformative social innovation across the set of articles are discussed. Third, an overview is provided of the different empirical examples of game-changers and transformative social innovations addressed; examples were drawn from different geographical contexts across Europe, North America, South America, Africa, and Asia. Fourth, the differing epistemological approaches used to explain social change are noted, and lessons for interdisciplinary and transdisciplinary research on social change discussed. Finally, a synthesis is provided of the main insights and contributions to the literature.
