π Topic Summary
Hierarchical diffusion is the spread of a trend or idea from persons or nodes of authority or power to other persons or places. Think of it like a ripple effect, often starting in major cities and then trickling down to smaller towns. This pattern occurs because the early adopters are typically connected to major hubs of innovation and influence. For example, a new fashion trend might originate in Paris or New York before appearing in local boutiques.
