This document summarizes the Law of Diffusion of Innovation, which explains how new ideas or products gain adoption over time through a population. It identifies five factors that influence adoption - relative advantage, compatibility, complexity, triability, and observability. It then applies this model to categorizing the Charles Koch Institute network into innovators, early adopters, early majority, late majority, and laggards. For each group, it identifies their needs and how CKI can engage them to further the diffusion of ideas. Resources on starting movements and applying these diffusion principles are also provided.
