The role of committed minorities in shaping public opinion has been recently addressed with the help of multiagent models. However, previous studies focused on homogeneous populations where zealots stand out only for their stubbornness. Here we consider the more general case in which individuals are characterized by different propensities to communicate. In particular, we correlate commitment with a higher tendency to push an opinion, acknowledging the fact that individuals with unwavering…

Opinion Formation Dynamics with Contrarians and Zealots
Mean-field type ODE models for opinion dynamics often assume that the entire population is comprised of congregators, who are agreeable. On the other hand, a contrarian opinion dynamics ODE model
The Role of Active Leaders in Opinion Formation on Social Networks
The intentional polarization of opinions and controlled changes of a consensus represent potentially harmful processes for any liberal society. Within the framework of a simple model for constructive
Human collective behavior models: language, cooperation and social conventions
This thesis presents the first extensive quantitative analysis of the phenomenon of norm change by looking at 2,365 orthographic and lexical norms shifts occurred in English and Spanish over the last two centuries as recorded by millions of digitized books.
Can honesty survive in a corrupt parliament?
In this work, we study a simple model of social contagion that aims to represent the dynamics of social influences among politicians in an artificial corrupt parliament. We consider an agent-based
Collective Dynamics of Belief Evolution under Cognitive Coherence and Social Conformity
This work proposes a unifying framework that connects cognitive and social forces together in order to study the dynamics of societal belief evolution, and argues that the inclusion of cognitive factors into a social model could provide a more complete picture of collective human dynamics.
The impact of variable commitment in the Naming Game on consensus formation
This work studies the effect that making commitment variable has on the dynamics of the system and shows that if different nodes have different values of w, higher standard deviation of w increases the critical fraction for waning commitment and decrease this fraction for increasing commitment.
Manipulating the Online Marketplace of Ideas.
A model of information spreading where agents prefer quality information but have limited attention is introduced, and it is found that infiltrating a critical fraction of the network is more damaging than generating attention-grabbing content or targeting influentials.
The emergence of consensus: a primer
This short review focuses on those situations in which consensus emerges ‘spontaneously’ in the absence of centralized institutions and covers topics that include the macroscopic consequences of the different microscopic rules of behavioural contagion.


Social consensus through the influence of committed minorities
We show how the prevailing majority opinion in a population can be rapidly reversed by a small fraction p of randomly distributed committed agents who consistently proselytize the opposing opinion
Activist Challenges to Deliberative Democracy
Screen and song celebrate social justice movements that protested in the streets when they were convinced that existing institutions and their normal procedures only reinforced the status quo. Many
Social Movements, Mobilization, and Contestation in the Middle East and North Africa
Before the 2011 uprisings, the Middle East and North Africa were frequently seen as a uniquely undemocratic region with little civic activism. The first edition of this volume, published at the start
Collective action and the civil rights movement
Collective Action and the Civil Rights Movement is a theoretical study of the dynamics of public-spirited collective action as well as a substantial study of the American civil rights movement and
Persistent Pacifism: How Activist Commitment is Developed and Sustained
How and why do activists persist in their commitment to a social movement beyond its initial mobilization phase? How do they manage their commitments? What role does creativity play in helping them
Encouraging moderation: clues from a simple model of ideological conflict.
Seven plausible strategies for deradicalizing a society are tested and it is found that only one of them significantly expands the moderate subpopulation without risking its extinction in the process.
Connect and win: The role of social networks in political elections
It is found that for a large region of the parameter space the result of the competition between the two parties allows for the existence of pluralism in the society, where both parties have a finite share of the votes.

The Journal of Peace Research (JPR) celebrates 50 years in 2014. Thematically, JPR is broadly oriented. The journal encourages a wide conception of peace, but focuses on the causes of violence and
The spontaneous emergence of conventions: An experimental study of cultural evolution
Experimental results are presented that demonstrate the spontaneous creation of universally adopted social conventions and show how simple changes in a population’s network structure can direct the dynamics of norm formation, driving human populations with no ambition for large scale coordination to rapidly evolve shared social conventions.
