AbstractDespite having faced severe criticism in the past, mereological approaches to group ontology, which argue that groups are wholes and that groups members are parts, have recently managed a comeback. Authors such as Katherine Ritchie and Paul Sheehy have applied neo-Aristotelian mereology to groups, and Katherine Hawley has defended mereological approaches against the standard objections in the literature. The present paper develops the mereological approaches to group ontology further and proposes an analysis of group membership as parthood plus further restrictions. While all mereological accounts agree that group members are parts of the group, it has become clear that this analysis is insufficient. I discuss three proposals to develop the mereological analysis of group membership and then put forward a combined solution to the puzzle. According to my proposal, the members of a reading group are agents who are part of the group and have been designated to contribute to the group.

When a group or institution issues a declarative statement, what sort of speech act is this? Is it the assertion of a single individual (perhaps the group’s spokesperson or leader) or the assertion of all or most of the group members? Or is there a sense in which the group itself asserts that p? If assertion is a speech act, then who is the actor in the case of group assertion? These are the questions this chapter aims to address. Whether groups themselves can make assertions or whether a group of individuals can jointly assert that p depends, in part, on what sort of speech act assertion is. The literature on assertion has burgeoned over the past few years, and there is a great deal of debate regarding the nature of assertion. John MacFarlane has helpfully identified four theories of assertion. Following Sandy Goldberg, we can call these the attitudinal account, the constitutive rule account, the common-ground account, and the commitment account. I shall consider what group assertion might look like under each of these accounts and doing so will help us to examine some of the accounts of group assertion (often presented as theories of group testimony) on offer. I shall argue that, of the four accounts, the commitment account can best be extended to make sense of group assertion in all its various forms.

Objective: To profile the posts on open orthodontic Facebook groups and identify which communication strategies and media modalities generate the most engagement from users. Design: A cross-sectional content analysis. Setting: Facebook Internet-based search. Methods: Post data were collected over a one-month period from the 10 largest public orthodontic Facebook groups. Evaluation of group characteristics included membership levels, number of administrators, time each group had been in existence and growth rate of each group. The number of posts, the numbers and types of engagement (likes, emojis, comments, shares) and engagement rate were calculated. The communication strategies (e.g. case presentation, course promotion, etc.) and media modalities (e.g. plain text, photograph, etc.) were recorded. Results: The study identified 190,268 Facebook members from the 10 largest orthodontic Facebook groups (median 17,811; interquartile range [IQR] 11,977). The median time the groups had existed was six years (median 2175 days; IQR 2311 days) and the median number of new group members in the past month was 1257 (IQR 2773). The median number of new group members in the past month was 1257 (IQR 2773). There were 227 postings during the study period with 2546 engagements. The overall median number of engagements was 196 (IQR 445) and the engagement rate of posts was 1.3% overall. Posts relating to course promotion (n = 63, 28%) followed by product promotion (n = 42, 19%) were the most common. Case presentation style posts accounted for 15% (n = 35). The level of engagement was greater for posts that had a clinical component compared to posts that did not ( P < 0.001). For media modality, posts that included a photograph had greater engagement ( P < 0.001). Conclusion: There are frequent posts on course and product promotion in orthodontic Facebook groups; however, these are associated with low levels of engagement. Posts that are clinically orientated and include photographs have higher levels of engagement.

Les programmes d’intervention en contexte de nature et d’aventure (INA) font l’objet d’études depuis plus d’une cinquantaine d’années. Malgré la reconnaissance des effets qui leur sont attribués, peu de travaux portent sur les processus s’opérant dans ces interventions. L’objectif de cet article est d’identifier ces processus et de mieux comprendre leur influence sur l’expérience de groupe. Pour ce faire, le modèle des facteurs d’aide (FA) a été retenu. Des entrevues semi-dirigées ont été réalisées auprès de 23 sujets âgés de 17 à 21 ans ayant participé à une expédition de 18 jours. Les éléments-clés de l’INA sont les suivants : la multitude de défis, la déstabilisation, la relation entre les enseignants et les participants et le milieu naturel. Ensuite, leur relation avec les FA est mise en relief. Il est question de : l’altruisme, les comportements d’imitation, la cohésion, la connaissance de soi, le partage d’information, l’universalité et les techniques de socialisation. Les apprentissages interpersonnels, la catharsis, l’espoir, les facteurs existentiels et la récapitulation corrective de la famille sont absents. Ces résultats mettent en lumière l’interaction entre les éléments-clés de l’INA et les FA, et la pertinence de s’y intéresser en travail social de groupe.A number of studies have addressed outdoor and adventure programs over the past fifty years. Despite empirical evidence that demonstrates the personal benefits of these programs, research investigating the key features responsible for these effects is scarce. The purpose of this article is to identify them and understand their influence. In order to achieve this goal, the data were examined from the perspective of helping factors (HFs). Semi-structured interviews were undertaken with 23 subjects aged between 17 and 21 who had participated in an 18 day expedition. The results show that participation in the program promoted key features: multiple challenges, the experience of destabilization, the relationship between the facilitators and group members and finally, the experience of being in wilderness. Then, relationships between key features and HFs are highlighted. Many of them are found: altruism, imitative behavior, cohesiveness, self-understanding, imparting information, development of socializing techniques, and universality. Interpersonal learning, catharsis, hope, existential factors, and corrective recapitulation of the primary family group are absent. These results give a better understanding of how key features interact with HFs in nature and adventure settings and its relevance in social work with groups.

Cumulative Cultural Evolution

Surprisingly little is known about how social groups influence social learning. Although several studies have shown that people prefer to copy in-group members, these studies have failed to resolve whether group membership genuinely affects who is copied or whether group membership merely correlates with other known factors, such as similarity and familiarity. Using the minimal-group paradigm, we disentangled these effects in an online social-learning game. In a sample of 540 adults, we found a robust in-group-copying bias that (a) was bolstered by a preference for observing in-group members; (b) overrode perceived reliability, warmth, and competence; (c) grew stronger when social information was scarce; and (d) even caused cultural divergence between intermixed groups. These results suggest that people genuinely employ a copy-the-in-group social-learning strategy, which could help explain how inefficient behaviors spread through social learning and how humans maintain the cultural diversity needed for cumulative cultural evolution.

The capacity to empathize with others facilitates prosocial behavior. People’s willingness and capacity to empathize, however, is often contingent upon the target’s group membership – people are less empathic towards those they categorize as out-group members. In competitive or threatening intergroup contexts, people may even feel pleasure (counter-empathy) in response to out-group members’ misfortunes. Social dominance orientation (SDO), or the extent to which people prefer and promote group-based inequalities, is an ideological variable that is associated with a competitive view of the world, increased prejudicial attitudes, and decreased empathy. Thus, higher levels of SDO should be associated with reduced empathy and increased counter-empathy in general, but especially towards those whose subjugation maintains group inequalities. Across three studies we show that among White individuals, higher SDO levels are associated with less empathy, and more counter-empathy in response to others’ good and bad fortunes. More importantly, these reductions in empathy and increases in schadenfreude as a function of SDO were significantly stronger for Asian and Black targets than for in-group White targets when group boundaries were made salient prior to the empathy ratings. Finally, in a fourth study we show that this phenomenon is not dependent upon a history of status differences: higher SDO scores were associated with decreased empathy and increased counter-empathy for competitive out-group (relative to in-group) targets in a novel group setting. We discuss implications of these effects for hierarchy maintenance.

Media Choices

This study provides a clearer understanding of how audience members’ race influences their media choices. It finds that in today’s overwhelmingly negative media environment, people prefer reading negative stories about persons in their own racial group over stories about racial out-group members. This suggests social movements seeking to change the attitudes of people of different races using media (e.g., Black Lives Matter) might not be as successful as those in the past (e.g., Civil Rights Movement). Today, people tend to ignore such news when there is other bad news that affects people in their own racial group.

AbstractWe present a refined moving group membership diagnostics scheme based on Bayesian inference. Compared to the BANYAN II method, we improved the calculation by updating bona fide members of a moving group, field star treatment, and uniform spatial distribution of moving group members. Here, we present the detailed description of our method and the new results for Bayesian membership calculation. Comparison of our method with BANYAN II shows probability differences up to ~90%. We conclude that more cautious consideration is needed in moving group membership based on Bayesian inference.

While we know that the degree to which humans are able to cooperate is unrivalled by other species, the variation humans actually display in their cooperative behaviour has yet to be fully explained. This may be because research based on experimental game-theoretical studies neglects fundamental aspects of human sociality and psychology, namely social interaction and language. Using a new optimal foraging game loosely modelled on the prisoner's dilemma, the egg hunt, we categorized players as either in-group or out-group to each other and studied their spontaneous language usage while they made interactive, potentially cooperative decisions. Both shared group membership and the possibility to talk led to increased cooperation and overall success in the hunt. Notably, analysis of players' conversations showed that in-group members engaged more in shared intentionality, the human ability to both mentally represent and then adopt another's goal, whereas out-group members discussed individual goals more. Females also helped more and displayed more shared intentionality in discussions than males. Crucially, we show that shared intentionality was the mechanism driving the increase in helping between in-group players over out-group players at a cost to themselves. By studying spontaneous language during social interactions and isolating shared intentionality as the mechanism underlying successful cooperation, the current results point to a probable psychological source of the variation in cooperation humans display.

Many scholars draw on evidence from evolutionary biology, behavioral economics, and infant research to argue that humans are “noble savages,” endowed with indiscriminate kindness. We believe this is mistaken. While there is evidence for an early-emerging moral sense—even infants recognize and favor instances of fairness and kindness among third parties—altruistic behaviors are selective from the start. Babies and young children favor people who have been kind to them in the past and favor familiar individuals over strangers. They hold strong biases for in-group over out-group members and for themselves over others, and indeed are more unequivocally selfish than older children and adults. Much of what is most impressive about adult morality arises not through inborn capacities but through a fraught developmental process that involves exposure to culture and the exercise of rationality.
