Stable diffusion can also occur in social movements, where a new idea or movement spreads and becomes widely adopted in a stable and predictable manner. One example of this is the movement for marriage equality.
The movement for marriage equality began in the United States in the 1990s and slowly gained momentum over the next two decades. The movement was successful in large part because it followed a predictable pattern of adoption, with early adopters being followed by a larger group of mainstream supporters, and then by the late majority.
The movement for marriage equality also benefited from a number of other factors that contributed to stable diffusion. For example, it had strong leadership, effective messaging, and support from a wide range of allies, including civil rights groups, faith communities, and political leaders.
Another example of stable diffusion in social movements is the #MeToo movement. The movement began in 2017 and quickly spread around the world as more and more people shared their stories of sexual harassment and assault. Like the movement for marriage equality, the #MeToo movement followed a predictable pattern of adoption, with early adopters being followed by a larger group of mainstream supporters.
The success of the #MeToo movement was also due to a number of other factors, including the power of social media to amplify voices, the bravery of survivors who shared their stories, and the support of allies who helped to spread the message.
