Diffusion of Innovation explains how a new practice can diffuse through a social system to the point where it becomes a social norm. Ultimately, community members, regardless of whether they have had contact with the original trendsetters, are expected to adopt the new behavior as it diffuses throughout the community’s social networks. Members of the social system in question pass through the stages of the innovation-decision process (awareness, knowledge, persuasion, adoption, and implementation) at different rates, leading to the well-known categories of acceptors: from innovators to laggards.
