Cascade (theory of diffusion)

The cascade theory of diffusion describes how innovations or new ideas spread through a population in stages, like a series of falling dominoes. It suggests that early adopters influence others, who then influence more people, creating a ripple effect. Each person’s decision to adopt depends on social influence, perceived benefits, and timing. The process continues as the innovation gradually reaches a wider audience, eventually becoming mainstream. This theory helps explain the patterns and speed at which new technologies, practices, or ideas are adopted within societies or groups.
