Oxytocin has ‘Tend-and-Defend’ Functionality in Group Conflict Across Social Vertebrates

Across vertebrate species, intergroup conflict confronts individuals with a tension between group interests best served by participation in conflict and personal interest best served by not participating. Here, we identify the neurohormone oxytocin as pivotal to the neurobiological regulation of this tension in distinctly different group-living vertebrates, including fish, birds, rodents, non-human primates, and humans. In the context of intergroup conflict, a review of emerging work on pro-sociality suggests that oxytocin and its fish and birds homologs, isotocin and mesotocin, respectively, can elicit participation in group conflict and aggression. This is because it amplifies (i) concern for the interests of genetically related or culturally similar ‘in- group’ others, and (ii) willingness to defend against outside intruders and enemy conspecifics. Across a range of social vertebrates, oxytocin can induce aggressive behaviour to ‘tend-and- defend’ the in-group during intergroup contests.

Games and enculturation: A cross-cultural analysis of cooperative goal structures in Austronesian games

While most animals play, only humans play games. As animal play serves to teach offspring important life-skills in a safe scenario, human games might, in similar ways, teach important culturally relevant skills. Humans in all cultures play games; however, it is not clear whether variation in the characteristics of games across cultural groups is related to group-level attributes. Here we investigate specifically whether the cooperativeness of games covaries with socio-ecological differences across cultural groups. We hypothesize that cultural groups that engage in frequent inter-group conflict, cooperative sustenance acquisition, or that have less stratified social structures, might more frequently play cooperative games as compared to groups that do not share these characteristics. To test these hypotheses, we gathered data from the ethnographic record on 25 ethnolinguistic groups in the Austronesian language family. We show that cultural groups with higher levels of inter-group conflict and cooperative land-based hunting play cooperative games more frequently than other groups. Additionally, cultural groups with higher levels of intra-group conflict play competitive games more frequently than other groups. These findings indicate that games are not randomly distributed among cultures, but rather relate to the socio-ecological settings of the cultural groups that practice them. We argue that games serve as training grounds for group-specific norms and values and thereby have an important function in enculturation during childhood. Moreover, games might server an important role in the maintenance of cultural diversity.

Experimental evidence for delayed post-conflict management behaviour in wild dwarf mongooses

In many species, within-group conflict leads to immediate avoidance of potential aggressors or increases in affiliation, but no studies have investigated delayed post-conflict management behaviour. Here, we experimentally test that possibility using a wild but habituated population of dwarf mongooses (Helogale parvula). First, we used natural and playback-simulated foraging displacements to demonstrate that bystanders take notice of the vocalisations produced during such within-group conflict events but that they do not engage in any immediate post-conflict affiliative behaviour with the protagonists or other bystanders. We then used another playback experiment to assess delayed effects of within-group conflict on grooming interactions: we examined affiliative behaviour at the evening sleeping burrow, 30–60 min after the most recent simulated foraging displacement. Overall, fewer individuals groomed on evenings following an afternoon of simulated conflict, but those that did groomed more than on control evenings. Subordinate bystanders groomed with the simulated aggressor significantly less, and groomed more with one another, on conflict compared to control evenings. Our study provides experimental evidence that dwarf mongooses acoustically obtain information about within-group contests (including protagonist identity), retain that information, and use it to inform conflict-management decisions with a temporal delay.

Are the Organisational Management Characteristics of Healthcare Organisations Distinguishable from Other Professional Organisations?

Organisational management characteristics occur with varying rates across industries and organisations within industries. While professional organisations tend to have fewer undesirable management characteristics than non-professional organisations, little work has been done to assess whether healthcare, with its unique legal structure that can put hospital administration at odds with physician autonomy, is an exception among professional organisations. In this study, rates of positive as well as undesirable management practices were estimated from publicly available ethnography data and compared to data from non-healthcare professional settings. A structured literature review was conducted to validate the ethnography data and further explore possible mechanisms. The main finding is that healthcare professionals do have greater group conflict with administration than other professionals and that healthcare settings exhibit greater instances of unwritten rules than other professional organisations. Overall, our results suggest that common management practices in other professional settings may not fully apply to healthcare. The potential for group conflict between physicians and administration is higher than other autonomous professional fields. Healthcare administration may benefit from examining practices in non-professional settings for beneficial ideas in management innovation.

Talking to Children About Race, Gender, and Social Issues: Review and Recommendations

Children notice group conflict and societal injustices. Educators and caregivers sometimes shield children from challenging social issues because they think that children cannot understand complex topics or because they think learning the information will be harmful. By avoiding such conversations, educators and caregivers are ignoring societal structures that privilege some groups over others. Children are aware of current events, social issues, and differences between people. They come to their own conclusions about the observed differences and differential treatment but without the tools to challenge biases and inequities. This brief reviews research on children’s developmental capacity to understand discrimination, with a focus on early-to-middle childhood and topics related to race, gender, and immigration status. Implications for policy and practice appear alongside recommendations, with a particular focus on the benefits to having these challenging conversations in schools.

Fooling ourselves and others: confirmation bias and the trustworthiness of qualitative research – Part 1 (the threats)

PurposeTo describe the implicit epistemic flaw of “confirmation bias” and to illustrate and evaluate the threats to qualitative research trustworthiness from that bias.Design/methodology/approachThe article overviews evidence and analysis from a wide range of disciplines. The adverse effect of three varieties of confirmation bias is described in some detail in illustrative examples.FindingsIt is argued that the threats from the bias go to the heart of the research. A subsequent article summarizes and critiques counter-arguments.Practical implicationsDiscussions and illustrations of varieties of confirmation bias can increase awareness of the unwitting bias and reduce its influence.Social implicationsThe bias not only threatens the trustworthiness of academic and other professional research but also underpins much ideological extremism, the effectiveness of post-truth politics and inter- and intra-group conflict. These are directly discussed in the article.Originality/valueThe article extends and enriches descriptions of threats to the trustworthiness of qualitative from confirmation bias. Such threats are inadequately recognized in many qualitative research arenas. It identifies a previously unrecognized variety of confirmation bias: hollow citations.

Calamities, Common Interests, Shared Identity: What Shapes Altruism and Reciprocity?

We conduct a large-scale survey experiment in nine European countries to study how priming a major crisis (COVID-19), common economic interests, and a shared identity influences altruism, reciprocity and trust of EU citizens. We find that priming the COVID-19 pandemic increases altruism and reciprocity towards compatriots, citizens of other EU countries, and non-EU citizens. Priming common European values also boosts altruism and reciprocity but only towards compatriots and fellow Europeans. Priming common economic interests has no tangible impact on behaviour. Trust in others is not affected by any treatment. Our results are consistent with the parochial altruism hypothesis, which asserts that because altruism arises out of inter-group conflict, humans show a tendency to favor members of their own groups.
