Leaderless Group Decisions

Leaderless group decision-making denotes the idea that political decisions from a non-hierarchical discussion structure can be more legitimate and effective than those from a hierarchical structure. Since the latter half of the 20th century, such decision-making has been practiced widely in community groups, non-governmental organizations (NGOs), “deliberation” forums, as well as in the business and management settings. While one may argue its origins go back to Athenian direct democracy, it was the zeal of the 1960s participatory democracy movement in the United States that produced the more sophisticated principles, philosophies, and mechanics of leaderless group decision-making. The progressive social movement activists at that time considered non-hierarchical groups as ethically appropriate to their causes. Since then, this tradition of leaderless group decision-making processes has been adopted in many grassroots social movements. Debates and controversies abound concerning leaderless group decision-making. It has been a normative imperative for many social activists to adopt decision-making in a leaderless manner. Research to date, however, has produced no conclusive evidence that leaderless group discussion results in better or more effective decisions. Proponents argue that members of a leaderless group would develop greater capacities for self-governance because in such a setting they can take more personal and egalitarian initiatives to organize activities of the group. This, in turn, would lead to better group dynamics and discussion, and, eventually, better decisions. Critics suggest that leaderless groups are slow and inflexible in decision-making and that the supposedly leaderless groups usually end up with leaders because of the social dynamics and human nature present in group interactions. Regardless of its potential benefits and problems, the ideals of deliberative and participatory democracy are strongly propelling this egalitarian, discourse-based form of group decision-making. Researchers will gain a great deal of insight from literature in deliberation concerning the functions, problems, and future directions of leaderless groups. In addition, there is a need to study leaderless groups in a more multi-faceted way, as research to date has been dominated by psychology-based quantitative assessment of groups. Qualitative and ethnographic approaches will be helpful to further assess the dynamics of leaderless group decision-making.

Much recent research indicates that discussion predictably affects responses to choice-dilemma items. In the present experiment, 12 choice-dilemma items were discussed to consensus by 40 female groups of varying size (2, 3, 5, or 7 members). Group size did not significantly affect shift scores. Over all groups, the mean of initial risk taking on an item was an excellent predictor of the mean amount of shift that item elicited ( r = –.89), a finding consistent with certain models of group decision making as well as with the idea that discussion arguments enhance dominant values. Further analyses of the present and past research indicated that the group decision making models could not account for the observed shifts.

The purpose of this study was a comparison of influence of formal status on group decision making for two cultures, the United States and India. Two identical experiments were conducted on American and Indian subjects. In both samples 36 male and female students, 12 graduate MBA and 24 freshmen or sophomores were randomly assigned to 12 groups of three in such a way that each group comprised of one graduate and two undergraduate members. Graduate students and undergraduates respectively represented high and low “specific” statuses, while male and female students respectively represented high and low “diffuse” statuses. Prior to group discussions, the participants introduced themselves to the group by stating, among other things, their academic status. Two standard “choice-dilemma” problems were discussed by each group with the order of the problems randomly counterbalanced. The experimental procedure followed the “risky shift” paradigm. Analysis of variance revealed that educational status had significant effects for both samples: graduate students “complied” and were persuaded less and were perceived as more competent-influential than undergraduates. However, there was a substantial difference between the Indian and the U.S. samples in the status effects of gender: gender had significant main status effects on “compliance”, persuasion, and perceived competence-influence only for the Indian sample. These findings are consistent with our understanding of relatively more status-conscious and male-dominated society in India than in USA.

Research into group decision-making suggests that, dependent on the information distributed prior to a group discussion, the decision and discussion content can be predicted. While the impact to group decision-making has been studied, its impact on collaborative activities such as design review has not been well investigated. A full factorial design of experiments (3×3, DOE) is conducted to investigate the influence of group cohesion and the awareness of the presence of unshared information among group members on design review effectiveness. The results suggest that awareness may have an effect on locating design issues by representation, functional group domain, and the total amount of design issues located.

AbstractMany agent-based models (ABMs) try to explain large-scale phenomena by reducing them to behaviors at lower scales. At these scales in social systems are functional groups such as households, religious congregations, coops and local governments. The intra-group dynamics of functional groups often generate inefficient or unexpected behavior that cannot be predicted by modeling groups as basic units. We introduce a framework for modeling intra-group decision-making and its interaction with social norms, using the household as our focus. We select phenomena related to women’s empowerment in agriculture as examples influenced by both intra-household dynamics and gender norms. Our framework proves more capable of replicating these phenomena than two common types of ABMs. We conclude that it is not enough to build multi-scale models; explaining social behaviors entails modeling intra-scale dynamics.
