Critical mass sociodynamics In social dynamics critical mass

Critical mass (sociodynamics) • In social dynamics, critical mass is a sufficient number of adopters of an innovation in a social system so that the rate of adoption becomes self-sustaining and creates further growth. It is an aspect of theory of diffusion of innovations, written extensively on by Everett Rogers in his book Diffusion of Innovations. • Social factors influencing critical mass may involve the size, interrelatedness and level of communication in a society or one of its subcultures. Another is social stigma, or the possibility of public advocacy due to such a factor. 2

Critical mass (sociodynamics) • Critical mass may be closer to majority consensus in political circles, where the most effective position is more often that held by the majority of people in society. In this sense, small changes in public consensus can bring about swift changes in political consensus, due to the majority-dependent effectiveness of certain ideas as tools of political debate. • Critical mass is a concept used in a variety of contexts, including physics, group dynamics, politics, public opinion, and technology. 3
