Models of Opinion Formation: Influence of Opinion Leaders
This paper studies the evolution of the distribution of opinions in a population of individuals in which there exist two distinct subgroups of highlycommitted, well-connected opinion leaders endowed with a strong convincing power. Each individual, located at a vertex of a directed graph, is characterized by her name, the list of people she is interacting with, her level of awareness, and her op...
متن کاملOpinion Leaders, Influence Activities and Leadership Rents∗
Consumers may observe previous consumers’ choices. They may follow their choices if they think these consumers are better informed. In turn, firms may concentrate on influencing the early consumers. This, in turn, changes the nature of early consumers’ choice behavior as a signal for other consumers. In this paper I show that firms’ influence activities need not distort earlier consumers’ decis...
متن کاملKinetic models of opinion formation
We introduce and discuss certain kinetic models of (continuous) opinion formation involving both exchange of opinion between individual agents and diffusion of information. We show conditions which ensure that the kinetic model reaches non trivial stationary states in case of lack of diffusion in correspondence of some opinion point. Analytical results are then obtained by considering a suitabl...
متن کاملA microfoundation of social influence in models of opinion formation
Models of opinion formation are used to investigate many collective phenomena. While social influence often constitutes a basic mechanism, its implementation differs between the models. In this paper, we provide a general framework of social influence inspired by the social psychological concept of cognitive dissonance. We only premise that individuals strive to minimize dissonance resulting fr...
متن کاملOpinion formation in networked societies with strong leaders
Recent studies show that many types of human social activities, from scientific collaborations to sexual contacts, can be understood in terms of complex network of interactions. Such networking paradigm allows to model many aspects of social behaviour with relatively simple computer models. The present work investigates the influence of single leaders on opinion formation within simulations of ...
