There is a substantial class of collective decision problems whose successful solution requires interdependence among decision makers at the agenda-setting stage and independence at the stage of choice. We define this class of problems and describe and apply a search-and-decision mechanism theoretically modeled in the context of honeybees and identified in earlier empirical work in biology. The honeybees’ mechanism has useful implications for mechanism design in human institutions, including courts, legislatures, executive appointments, research and development in firms, and basic research (...) in the sciences. Our paper offers a fresh perspective on the idea of “biomimicry” in institutional design and raises the possibility of comparative institutional analysis across species. (shrink)

In this article, I consider how recent work on the philosophy of group-agency and shared-agency can help us to understand what it is for a church to act in worship. I argue that to assess a model’s suitability for providing such an account, we must consider how well it handles cases of non-paradigm participants, such as those with autism spectrum disorder and young infants. I suggest that whilst a shared-agency model helps to clarify how individuals coordinate actions in cases of (...) reading or singing liturgy, it does not handle non-paradigm cases well and so cannot be considered a suitable model of group liturgical action. Instead, I suggest that a model of groupagency, in which a plurality of action types can contribute to the actions of a group as a whole, is better suited to explaining a church’s actions in worship.

The resurgence of interest in collective behavior is in large part due to tools recently made available for conducting laboratory experiments on groups, statistical methods for analyzing large data sets reflecting social interactions, the rapid growth of a diverse variety of online self‐organized collectives, and computational modeling methods for understanding both universal and scenario‐specific social patterns. We consider case studies of collective behavior along four attributes: the primary motivation of individuals within the group, kinds of interactions among individuals, typical dynamics (...) that result from these interactions, and characteristic outcomes at the group level. With this framework, we compare the collective patterns of noninteracting decision makers, bee swarms, groups forming paths in physical and abstract spaces, sports teams, cooperation and competition for resource usage, and the spread and extension of innovations in an online community. Some critical issues surrounding collective behavior are then reviewed, including the questions of “Does group behavior always reduce to individual behavior?”“Is ‘group cognition’ possible?” and “What is the value of formal modeling for understanding group behavior?”.

When animals share decisions with others, they pool personal information, offset individual errors and, thereby, increase decision accuracy. This is termed ‘swarm intelligence.’ But what if those decisions involve conflicts of interest between individual decision-makers? Should animals share decisions with individuals whose goals are different from, and partially in conflict with, their own? A group decision model developed by Larissa Conradt and colleagues finds that, contrary to intuition, conflicting goals often increase both decision accuracy and the individual gains derived from (...) shared decisions. Thus, conflicts of interest, far from hampering effective decision making, can actually improve decision outcomes for all stakeholders, as long as they also have some goals in common. By contrast, conflict-free decisions shared by animals which all have the same goals are often surprisingly poor. (shrink)

In this paper, I aim to show that analytic philosophy can contribute to the theological discussion of ecclesiology. By considering recent analytic work on social ontology, I outline how we might think of the Church as one entity, constituted by many disparate parts. The paper begins with an overview of the theological constraints for the paper, and then proceeds to examine recent work on the philosophy of social ontology and group agency. Drawing on this literature, I outline three models of (...) social ontology from the history of philosophy and suggest reasons why all of them fail to provide an account of the Church’s agency. Finally, I develop an alternative model which, I suggest, better fits the conditions stipulated. (shrink)
