A Theory of Group Stability

  title={A Theory of Group Stability},
  author={Kathleen M. Carley},
  journal={American Sociological Review},
Some groups endure longer, are more stable, and are better able than other groups to incorporate new members or ideas without losing their distinctiveness. I present a simple model of individual behavior based on the thesis that interaction leads to shared knowledge and that relative shared knowlege leads to interaction. Using this model I examine the structural and cultural bases of group stability. Groups that are stable in the short run do not necessarily retain their distinctiveness in the…

The aim is to consider simple mathematical models incorporating a selection of social and psychological theory which will help a federation model the behavior of extremist groups, and determine not only when an intervention is necessary, but also the best course of action to take to induce the fracture of such groups.

Cultural Integration and Differentiation in Groups and Organizations

It is demonstrated that two empirically grounded mechanisms of social differentiation lead to different patterns of polarization, radicalization, and factionalism and the implications for cultural dynamics in organizations are discussed.

Similarity and Group Performance

This paper investigates the effects that different patterns of similarity among group members have on a group s performance on a problem-solving task. I discuss and test hypotheses on the effects of

A preliminary model of participation for small groups

It is demonstrated that the preliminary version of the participation model generates individual differences that in turn have a meaningful impact on group performance, and suggested that a group member’s location with respect to other group members and observers can be an important exogenous source of individual differences.

Exit, Cohesion, and Consensus: Social Psychological Moderators of Consensus among Adolescent Peer Groups

This study uses longitudinal data on adolescent social networks to show how meso-level social structures, such as informal peer groups, moderate the process of consensus formation, and uses a novel method for controlling for selection into a group to find that centralized peer groups have very low levels of consensus, while cohesive peer groups are found to have very high levels.

Models of Social Influence: Towards the Next Frontiers

It is proposed that a new generation of empirically-based computational social influence models can make unique contributions for understanding key societal challenges, like the possible effects of social media on societal polarization.

How Groups Can Foster Consensus: The Case of Local Cultures

The dynamics of agent interaction in clusters as modelled here, are conducive to consensus among all or a majority of agents, whereas for open-minded agents (high e) this does not necessarily hold.

The satisfaction and stress of being a market maven: A social network perspective

Compared with the average consumer, market mavens possess a unique set of characteristics including a greater depth of knowledge of the marketplace and its products, as well as a strong social

Creation, evolution, and dissolution of social groups

The utility that members gain from ingroup interactions as a function of the levels of homophily of opinions of group members with opinions of a given individual in this group is formally defined.

Friendship Patterns and Culture: The Control of Organizational Diversity

Organizational culture is often described as a management control device, but this view obscures the importance of informal social interactions for the emergence and modification of culture. We

Homophily in voluntary organizations: Status distance and the composition of face-to-face groups.

Recent work on the organized sources of network ties and on the social structural determinants of association are synthesized to produce several hypotheses about homophily. These hypotheses are
