Competitive Altruism

When there is an opportunity to gain a positive reputation, individuals are more willing to sacrifice their immediate self-interest. Partner choice creates opportunities for competitive altruism, i.e. individuals compete to be regarded as more generous and to be chosen for future partnerships. Tests of the competitive altruism hypothesis have focused so far on reputation based on direct observation, whereas the role of gossip has not been theoretically and empirically addressed. Partner choice can create an incentive to cooperate and to send truthful messages, but it can also work in the opposite direction. In order to understand the consequences of partner choice on cooperation and gossip, we designed an experimental study in which participants played a sequence of Public Goods games and gossip rounds. In our two treatments, we observed that cooperation increased when there was an opportunity to be selected, but also that cooperators sent more honest messages than defectors, and that this strategy was prevalent in the treatment in which inter-group competition was implemented. We also found evidence that participants detached themselves from the information more often when lying. Taken together, our study fills a theoretical and empirical gap by showing that partner choice increases both cooperation and honesty of gossip.

Benefits And Costs

Punishment and reputation-based mechanisms play a major role in supporting the evolution of human cooperation. Theoretical accounts and field observations suggest that humans use multiple tactics to intervene against offences—including confrontation, gossip and ostracism—which have unique benefits and costs. Here, we draw a distinction between direct punishment tactics (i.e. physical and verbal confrontation) and indirect reputation-based tactics (i.e. gossip and ostracism). Based on this distinction, we sketch the common and unique social functions that different tactics are tailored to serve and describe information-processing mechanisms that potentially underlie decisions concerning how to intervene against offences. We propose that decision rules guiding direct and indirect tactics should weigh information about the benefits of changing others' behaviour versus the costs of potential retaliation. Based on a synthesis of existing evidence, we highlight the role of situational, relational and emotional factors in motivating distinct punishment tactics. We suggest that delineating between direct and indirect tactics can inform debates about the prevalence and functions of punishment and the reputational consequences of third-party intervention against offences. We emphasize the need to study how people use reputation-based tactics for partner recalibration and partner choice, within interdependent relationships and social networks, and in daily life situations.

Honest Signalling

Large-scale non-kin cooperation is a unique ingredient of human success. This type of cooperation is challenging to explain in a world of self-interested individuals. There is overwhelming empirical evidence from different disciplines that reputation and gossip promote cooperation in humans in different contexts. Despite decades of research, important details of reputation systems are still unclear. Our goal with this theme issue is to promote an interdisciplinary approach that allows us to explore and understand the evolution and maintenance of reputation systems with a special emphasis on gossip and honest signalling. The theme issue is organized around four main questions: What are the necessary conditions for reputation-based systems? What is the content and context of reputation systems? How can reputations promote cooperation? And, what is the role of gossip in maintaining reputation systems and thus cooperation? This article is part of the theme issue ‘The language of cooperation: reputation and honest signalling’.

Signalling Theory

When one individual helps another, it benefits the recipient and may also gain a reputation for being cooperative. This may induce others to favour the helper in subsequent interactions, so investing in being seen to help others may be adaptive. The best-known mechanism for this is indirect reciprocity (IR), in which the profit comes from an observer who pays a cost to benefit the original helper. IR has attracted considerable theoretical and empirical interest, but it is not the only way in which cooperative reputations can bring benefits. Signalling theory proposes that paying a cost to benefit others is a strategic investment which benefits the signaller through changing receiver behaviour, in particular by being more likely to choose the signaller as a partner. This reputation-based partner choice can result in competitive helping whereby those who help are favoured as partners. These theories have been confused in the literature. We therefore set out the assumptions, the mechanisms and the predictions of each theory for how developing a cooperative reputation can be adaptive. The benefits of being seen to be cooperative may have been a major driver of sociality, especially in humans.

The Relationship

The idea and practice of sacrifice play a profound role in religion, ethics, and politics. This book explores the meaning and implications of sacrifice, developing a theory of sacrifice as an offering and examining the relationship between sacrifice, ritual, violence, and love. The book also looks at the place of self-sacrifice within ethical life and at the complex role of sacrifice as both a noble and destructive political ideal. In the religious domain, Halbertal argues, sacrifice is an offering, a gift given in the context of a hierarchical relationship. As such it is vulnerable to rejection, a trauma at the root of both ritual and violence. An offering is also an ambiguous gesture torn between a genuine expression of gratitude and love and an instrument of exchange, a tension that haunts the practice of sacrifice. In the moral and political domains, sacrifice is tied to the idea of self-transcendence, in which an individual sacrifices his or her self-interest for the sake of higher values and commitments. While self-sacrifice has great potential moral value, it can also be used to justify the most brutal acts. The book attempts to unravel the relationship between self-sacrifice and violence, arguing that misguided self-sacrifice is far more problematic than exaggerated self-love. Through the book's exploration of the positive and negative dimensions of self-sacrifice, it also addresses the role of past sacrifice in obligating future generations and in creating a bond for political associations, and considers the function of the modern state as a sacrificial community.

Ethnographic Data

Why do humans, uniquely among animals, cooperate in large numbers to advance projects for the common good? Contrary to the conventional wisdom in biology and economics, this generous and civic-minded behavior is widespread and cannot be explained simply by far-sighted self-interest or a desire to help close genealogical kin. This book shows that the central issue is not why selfish people act generously, but instead how genetic and cultural evolution has produced a species in which substantial numbers make sacrifices to uphold ethical norms and to help even total strangers. The book describes how, for thousands of generations, cooperation with fellow group members has been essential to survival. Groups that created institutions to protect the civic-minded from exploitation by the selfish flourished and prevailed in conflicts with less cooperative groups. Key to this process was the evolution of social emotions such as shame and guilt, and our capacity to internalize social norms so that acting ethically became a personal goal rather than simply a prudent way to avoid punishment. Using experimental, archaeological, genetic, and ethnographic data to calibrate models of the coevolution of genes and culture as well as prehistoric warfare and other forms of group competition, the book provides a compelling and novel account of human cooperation.

<p></p><p>In the present experimental study different interaction ‘modes’ those took place between a psychologist and a child were tested for the role of these towards health recovery of the child? Following were the interaction modes, a) presenting a flower with smile plus inquiring about health, b) offering a blessing plus inquiring about health, c) making an indifferent presence plus inquiring about health with flat tone, d) inquiring about health with providing precautions about prognosis. It was assumed that all modes would differently influence health outcomes? 100 hospitalized children located in child wards of different hospitals with randomized pre-post block design interacted. One each from four interaction modes was used for a group of 25 participants each. Actual ward discharge was compared with anticipatory estimated by each ward in-charge to calculate effect of mode on outcome. Face Pain Scale, The Children Happiness Scale and a Demographic Sheet were also used. Results reflected ‘modes’ relationship with outcomes. More studies would clarify further.</p><br><p></p>

Role Of Information

Misinformation often continues to influence people’s cognition even after corrected (the ‘continued influence effect of misinformation’, the CIEM). This study investigated the role of information relevance in the CIEM by questionnaire survey and experimental study. The results showed that information with higher relevance to the individuals had a larger CIEM, indicating a role of information relevance in the CIEM. Personal involvement might explain the effects of information relevance on the CIEM. This study provides insightful clues for reducing the CIEM in different types of misinformation and misinformation with varying relevance.

Fluid Interpretation

BackgroundWhile no normative definition exists, medical professionalism emphasises a set of values, behaviours and relationships that underpin public trust in a physician. The empirical setting for this study is the Irish health care system where GPs receive income through a unique mix of private fee income and state funded capitation. GPs’ income per patient has fallen by 33% under state schemes between 2008 and 2013 due to changes in health policy and national fiscal constraints.AimThis paper examines how general practitioners conceptualise and operationalise medical professionalism and financial self-interest in the Irish healthcare system.MethodTo address this research aim, a historical documentary analysis (2009–2016) of national and medical newspapers was used to investigate GPs’ expressions of medical professionalism and financial self-interest.ResultsThe vagueness of language in differing definitions of medical professionalism may lead to a GP having a fluid interpretation depending on the situation. While general practitioners expressed core humanistic values, such as empathy and compassion, the expression of altruistic values were limited when practitioners indicated there was constraint on the financial resources of a practice.ConclusionCentral to the analysis of a medical practitioner’s treatment of patients and receipt of fee income is the tension between medical professionalism and financial self-interest. Developing an understanding of this tension has implications for those undertaking healthcare policy initiatives and the recruitment and retention of general practitioners in primary care.

This study addresses respiratory and motor impairments in an experimental reserpine-induced model of parkinsonism in rats. The role of chronic hypoxia due to diminished ventilation in the development and course of neurodegeneration is addressed. An attempt was made to distinguish between central and peripheral dopamine pathways in the mechanisms of neurodegeneration. A dissociation of putative mechanisms of respiratory and motor impairments is tackled as well. Although this purely experimental study cannot be directly extrapolated to human pathophysiology, the corollaries have been drawn concerning the potential repercussions of the respiratory and motor impairments for the physiotherapeutic procedures in the management of chronic neurodegeneration.
