Researchers from across the social sciences have found consistent deviations from the predictions of the canonical model of self-interest in hundreds of experiments from around the world. This research, however, cannot determine whether the uniformity results from universal patterns of human behavior or from the limited cultural variation available among the university students used in virtually all prior experimental work. To address this, we undertook a cross-cultural study of behavior in ultimatum, public goods, and dictator games in a range of (...) small-scale societies exhibiting a wide variety of economic and cultural conditions. We found, first, that the canonical model – based on self-interest – fails in all of the societies studied. Second, our data reveal substantially more behavioral variability across social groups than has been found in previous research. Third, group-level differences in economic organization and the structure of social interactions explain a substantial portion of the behavioral variation across societies: the higher the degree of market integration and the higher the payoffs to cooperation in everyday life, the greater the level of prosociality expressed in experimental games. Fourth, the available individual-level economic and demographic variables do not consistently explain game behavior, either within or across groups. Fifth, in many cases experimental play appears to reflect the common interactional patterns of everyday life. Key Words: altruism; cooperation; cross-cultural research; experimental economics; game theory; ultimatum game; public goods game; self-interest. (shrink)

We would like to thank the commentators for their generous comments, valuable insights and helpful suggestions. We begin this response by discussing the selfishness axiom and the importance of the preferences, beliefs, and constraints framework as a way of modeling some of the proximate influences on human behavior. Next, we broaden the discussion to ultimate-level (that is evolutionary) explanations, where we review and clarify gene-culture coevolutionary theory, and then tackle the possibility that evolutionary approaches that exclude culture might be sufficient (...) to explain the data. Finally, we consider various methodological and epistemological concerns expressed by our commentators. (shrink)

Home diagnostic testing is becoming part of the modern medical landscape, but many ethical and policy questions remain unresolved. Most of them first surfaced during the long regulatory deliberations over the home HIV test, the first home test for a contagious illness sold in the United States. Between 1989 and 2012, federal regulators and their consultants debated the ideal metrics for such a test, its benefits, and its potential harms for both individuals and communities. Ultimately, two iterations of the home (...) HIV test were marketed in the United States; neither one of them changed the course of the national HIV epidemic, as hoped. This failure has powerful implications for home testing for other contagious diseases. (shrink)

Various laws and theories in the natural and social sciences are presented with a view to discerning the syntactic and semantic characteristics of many idealizations in science. Three different kinds of idealizations are discussed: ideal conditions, ideal cases, and idealized theories. An ideal condition is a formula in which state variables occur, whose existential closure is false, and for which there is another formula that can be constructed out of the original formula such that the existential closure of the new (...) formula is true. An ideal case is a statement which is logically equivalent to a universal conditional which has an ideal condition as its antecedent. And an idealized theory is a set of false universal conditional statements. Alternative syntactic and semantic analyses are viewed and criticized. (shrink)

This paper explores the wartime creation of veterinary expertise in cattle breeding, and its contribution to the transition between two very different types of agriculture. During the interwar period, falling prices and steep competition from imports caused farmers to adopt a ‘low input, low output’ approach. To cut costs, they usually butchered, marketed or doctored diseased cows in preference to seeking veterinary aid. World War II forced a greater dependence on domestic food production, and inspired wide-ranging state-directed attempts to increase (...) agricultural output. However, the weak connection between veterinary services and livestock productivity meant that the drive for greater milk yields did not automatically translate into a demand for improved veterinary health care. Rather veterinary expertise had to be actively created and made relevant to the new context. Leaders of the profession secured this goal through establishing a government-backed ‘scheme for the control of certain diseases of dairy cows’. Drawing on pre-existing but rarely applied reproductive technologies, the scheme provided the opportunities and education necessary for more extensive veterinary interventions in cattle breeding. I show how its operation transformed understandings of fertility, raised veterinarians to the status of experts, won them the patronage of farmers and the state, and facilitated the shift to a productivity-oriented agriculture.

A brief discussion is offered of what it means to say that a set of statements provides D-N explanation with special emphasis given to approximative D-N explanation. An idealized theory is seen to provide approximative D-N explanation. An ideal case provides explanation only if postulates are offered which connect the ideal antecedent condition with actual conditions. Such postulates will help in accounting for deviations between what the consequent of the ideal case entails and what actually occurs. Three ways are presented (...) for deciding on the acceptability of idealizations: (i) as actual conditions more closely approximate the ideal antecedent conditions specified in an ideal case, the more closely actual cases ought to approximate the consequent of the ideal case; (ii) the additional postulates connecting ideal antecedent conditions with actual conditions ought to account for deviations between what is entailed by an idealized theory and what actually occurs; and (iii) an idealized theory is explained by a more general theory when certain state variables in the more general theory are given extreme values. It is argued that (iii) is not a necessary condition for the acceptability of idealizations. (shrink)

When fertility centers dispose of embryos, how should this be done? Current regulatory guidelines by the Human Fertilisation and Embryology Authority state that, when terminating the development of human embryos, a clinic should act with sensitivity, taking account of the embryo’s “special status” and respecting the interests of the gamete providers and recipients. As yet, it is unclear as to how and to what extent this achieved within fertility clinics in the UK. Resultantly, this paper examines the largely undocumented domain (...) of embryo disposal practice. By undertaking an empirical study into policy and procedure and noting divergence in clinic practice, it then comments on the ethical implications of these protocols for patients and practitioners. Specifically, this paper argues for a more holistic approach to embryo disposal. An approach that effectively meets the requirements of the lab, is respectful of the “special status” of the human embryo, and, perhaps most importantly, reflects the multifaceted needs of the patient.

Good decision-making requires reliable information. In medicine, relevant information comes from clinical trials and other forms of scientific research. In business, one source is in corporate annual financial statements. As for-profit, publicly traded companies whose business is discovering, manufacturing, and marketing drugs, pharmaceutical companies sit at the nexus of these two fields. Determining the safety and efficacy of a pharmaceutical product and determining the profitability of a complex enterprise are similarly difficult tasks: each is fraught with deeply ambiguous information that (...) requires sophisticated judgment to interpret reasonably.

This article examines the limitations associated with Irigaray’s concept of a culture of difference. I suggest that her concept of sexual difference depends upon a conservative fiction of sameness. I argue that a fiction of phallic sameness underpins her evangelical championing of difference, and that such a fiction retains a conservative blindness to the complexities of contemporary social relations and erases the positive effects oppositional discourses have had on the culture of modernity. I question the debt Irigaray disavows to other (...) non-difference feminism, her insistence that woman are radically marginalized and suggest that her culture of difference is prescriptive and normative. Egalitarian feminism, understood as a postmodern project, is far more strategic, insofar as it offers a multiply-situated analysis of the relationship between women and power within modernity. I replace Irigaray’s negative image of the egalitarian feminist as an unnatural woman with the figure of the cyborg who embraces ontological impurity and strategically works within culture. (shrink)

Responding to the polemic critiques of Quentin Tarantino’s 2012 film, Django Unchained, this essay uses Lacanian and Žižekian discussions of the gaze in order to understand what the film communicates about the racist ideology of American slavery. Tarantino’s film is at once more nuanced than most Hollywood films about the period and also more clearly problematic. Unlike other recent films about slavery in the United States, such as the recent Lincoln, in Django Unchained, every character other than a German bounty (...) hunter, Dr. King Schultz, is interpellated in the racist ideology that supports the institution of slavery; and the characters of the film, black and white alike, go to great lengths to preserve the ideology that rests on the subjugation of all black Americans. Tarantino’s rendition of this interpellation is made still more enjoyable as his main characters, Schultz, and the slave-turned-bounty-hunter, Django, embody two manifestations of the gaze, the screen and the stain or spot. However, because the Lacanian letter insists on arriving at the end of the film, the conclusion to Django Unchained also appears to suggest that the film’s villain, though physically defeated, was correct in his pronouncement that 9,999 out of 10,000 black people are biologically servile.

Most histories of livestock disease in Britain treat the development of control policy as a government responsibility, to which farmers made little constructive contribution. Similarly, farmers rarely appear in accounts of disease research. This paper uses the example of contagious abortion at the turn of the twentieth century to reveal that state-farming collaboration in research and policy did in fact occur, and that it operated in various ways, with often unexpected outcomes. The collaborative approach to contagious abortion is partly attributed (...) to its clinical and epidemiological features, which made it an unsuitable candidate for the existing, state-led policy of stamping out disease. It is claimed that such collaboration has been overlooked by historians on account of their focus upon diseases that were amenable to stamping out. This focus needs to change if history is to inform present-day disease governance in Britain, which is founded on the concept of ‘partnership’ between farmers and the state. (shrink)

People who have mental health diagnoses are often subject to sanist microaggressions in which pejorative terms to describe mental illness are used to represent that which is discreditable. Such microaggressions reflect and perpetrate stigma against severe mental illness, often held unconsciously as implicit bias. In this article, I examine the sanist attitudes that underlie sanist microaggressions, analyzing some of the cognitive biases that support mental illness stigma. Then I consider what responsibility we have with respect to microaggressions. I argue that (...) all people share in a collective responsibility to engage in acts of epistemic resistance that challenge sanist attitudes so that it is easier for bystanders who witness microaggressions, and targets of microaggressions in particular, to identify microaggressions and to point out biased behavior. The act of pointing out bias is best understood as an act of epistemic resistance that is more effective and meaningful in the context of other acts of epistemic resistance. Ultimately, whether to point out bias is an individual decision that one must make after weighing the risks involved; engaging in a range of acts of epistemic resistance, on the other hand, is a moral responsibility everyone shares.

With no statutory definition of death, the accepted medical definition relies on brain stem death criteria as a definitive measure of diagnosing death. However, the use of brain stem death criteria in this way is precarious and causes widespread confusion amongst both medical and lay communities. Through critical analysis, this paper considers the insufficiencies of brain stem death. It concludes that brain stem death cannot be successfully equated with either biological death or the loss of integrated bodily function. The overemphasis (...) of the brain-stem and its consequences leaves the criteria open to significant philosophical critique. Further, in some circumstances, the use of brain stem death criteria causes substantial emotional conflict for families and relatives. Accordingly, a more holistic and comprehensive definition of death is required. (shrink)

Background Human brain organoids are a valuable research tool for studying brain development, physiology, and pathology. Yet, a host of potential ethical concerns are inherent in their creation. There is a growing group of bioethicists who acknowledge the moral imperative to develop brain organoid technologies and call for caution in this research. Although a relatively new technology, brain organoids and their uses are already being discussed in media literature. Media literature informs the public and policymakers but has the potential for (...) utopian or dystopian distortions. Thus, it is important to understand how this technology is portrayed to the public. Methods To investigate how brain organoids are displayed to the public, we conducted a systematic review of media literature indexed in the Nexis Uni database from 2013–2019. News and media source articles passing exclusion criteria (_n_ = 93) were scored to evaluate tone and relevant themes. Themes were validated with a pilot sample before being applied to the dataset. Thematic analysis assessed article tone, reported potential for the technology, and the scientific, social, and ethical contexts surrounding brain organoids research. Results Brain organoid publications became more frequent from 2013 to 2019. We observed increases in positively and negatively toned articles, suggesting growing polarization. While many sources discuss realistic applications of brain organoids, others suggest treatment and cures beyond the scope of the current technology. This could work to overhype the technology and disillusion patients and families by offering false hope. In the ethical narrative we observe a preoccupation with issues such as development of artificial consciousness and “humanization” of organoid-animal chimeras. Issues of regulation, ownership, and accuracy of the organoid models are rarely discussed. Conclusions Given the power that media have to inform or misinform the public, it is important this literature provides an accurate and balanced reflection of the therapeutic potential and associated ethical issues regarding brain organoid research. Our study suggests increasing polarization, coupled with misplaced and unfounded ethical concern. Given the inhibitory effects of public fear or disillusion on research funding, it is important media literature provides an accurate reflection of brain organoids. (shrink)

Ramathal et al. have employed an elegant xenotransplantation technique to study the fate of human induced pluripotent stem cells (hiPSCs) from fertile males and from males carrying Y chromosome deletions of the azoospermia factor (AZF) region. When placed in a mouse testis niche, hiPSCs from fertile males differentiate into germ cell‐like cells (GCLCs). Highlighting the crucial role of cell autonomous factors in male sterility, hiPSCs derived from azoospermic males prove to be less successful under similar circumstances. Their studies argue that (...) the agametic “Sertoli cell only” phenotype of two of the AZF deletions likely arises from a defect in the maintenance of germline stem cells (GSCs) rather than from a defect in their specification. These observations underscore the importance of the dialogue between the somatic niche and its inhabitant stem cells, and open up interesting questions concerning the functioning of the somatic niche and how it communicates to the GSCs.

This book considers what responsibilities affluent individuals have toward global poverty, given that global poverty is a problem with structural, political causes, and one that generally requires collective action. By looking at the intersection of moral, political, and legal philosophy, this book gives a pluralistic and differentiated account of individual duties based on a person's moral agency, her roles within collective groups , and her institutional identities as citizen and consumer.

In this paper I explore the way that mental illness stigma impacts epistemic credibility in people who have mental illness. While any kind of stigma has the potential to discredit a person’s epistemic agency, in the case of mental illness the basis for discrediting is in some cases and to some extent justifiable, for impairments in rationality, control, and reality perception can indeed be obstacles to participating appropriately in epistemic activities such as normal conversation and public discourse. People with mental (...) illness are still potentially subject to epistemic injustices, however, especially when we rely on stereotypes and fail to make complicated and nuanced judgments which are more accurate. In this paper, I explain some of the ways that people with mental illness may be subject to epistemic injustices, and I propose some suggestions for how epistemic injustice can be avoided. (shrink)

In 1892, the British agricultural authorities introduced a policy of slaughtering animals infected with foot and mouth disease (FMD). This measure endured throughout the 20th century and formed a base line upon which officials superimposed the controversial "contiguous cull" policy during the devastating 2001 epidemic. Proponents of the slaughter frequently emphasized its capacity to eliminate FMD from Britain, and claimed that it was both cheaper and more effective than the alternative policies of isolation and vaccination. However, their discussions reveal that (...) a less obvious but nonetheless important reason for maintaining the slaughter policy was the conviction that in its manner of operation and its outcomes, it benefited the state and status of the British nation. To its supporters, slaughter was far more than a method of disease control; it acted also as a moralizing and civilizing force, an indicator of veterinary ability and a "virility symbol" of British international leadership. This "cultural" rationale for FMD control by slaughter declined during the late 20th century and was wholly undermined by the 2001 epidemic, when extensive culling failed to convey the intended image of an organized, enlightened Britain.

The distinctly contemporary proliferation of pornography and hate speech poses a challenge to liberalism's traditional ideal of a 'marketplace of ideas' facilitated by state neutrality about the content of speech. This new study argues that the liberal state ought to depart from neutrality to meet this challenge.

Empathy is a construct that is notoriously difficult to define. Murphy and colleagues ( 2022 ) argue for leaning into the construct's inherent fuzziness and reverting to what they term a classical definition informed by the observations of philosophers and clinicians: as a dynamic, “unfolding process of imaginatively experiencing the subjective consciousness of another person, sensing, understanding, and structuring the world as if one were that person.” Although consistent with some historical conceptualizations, this definition risks incorporating so many processes it (...) would make empathy difficult to operationalize or distinguish from any generally socially sensitive interaction. Defining empathy instead as the attempted representation, or simulation, of another's subjective internal experiences (whether sensory, affective, or cognitive) would increase its clarity and empirical utility.

The international protest surrounding the Copenhagen Zoo’s recent decision to kill a healthy giraffe in the name of population management reveals a deep moral tension between contemporary zoological display practices—which induce zoo-goers to view certain animals as individuals, quasi-persons, or friends—and the traditional objectives of zoos, which ask us only to view animals as specimens. I argue that these zoological display practices give rise to moral obligations on the part of zoos to their visitors, and thus ground indirect duties on (...) behalf of zoos to their animals. I conclude that zoos might take on interspecies friendship as a new zoological objective. (shrink)
