Ethics courses are most commonly evaluated using reaction measures. However, little is known about the specific types of reaction data being collected and how these reaction data relate to improvements in trainee performance. Using a sample of 381 ethics training sessions, major reaction data categories were identified. Content and course satisfaction were the most frequently collected types of reaction criteria. Furthermore, content relevance and course satisfaction showed strong, positive relationships with performance criteria, whereas content satisfaction demonstrated a moderate, negative relationship. (...) These results and future directions for ethics training evaluation are discussed. (shrink)

Traditional whistleblowing theories have purported that whistleblowers engage in a rational process in determining whether or not to blow the whistle on misconduct. However, stressors inherent to whistleblowing often impede rational thinking and act as a barrier to effective whistleblowing. The negative impact of these stressors on whistleblowing may be made worse depending on who engages in the misconduct: a peer or advisor. In the present study, participants are presented with an ethical scenario where either a peer or advisor engages (...) in misconduct, and positive and the negative consequences of whistleblowing are either directed to the wrongdoer, department, or university. Participant responses to case questions were evaluated for whistleblowing intentions, moral intensity, metacognitive reasoning strategies, and positive and negative, active and passive emotions. Findings indicate that participants were less likely to report the observed misconduct of an advisor compared to a peer. Furthermore, the findings also suggest that when an advisor is the source of misconduct, greater negative affect results. Post-hoc analyses were also conducted examining the differences between those who did and did not intend to blow the whistle under the circumstances of either having to report an advisor or peer. The implications of these findings for understanding the complexities involved in whistleblowing are discussed. (shrink)

Despite the growing body of literature on training in the responsible conduct of research, few studies have examined the effectiveness of delivery formats used in ethics courses. The present effort sought to address this gap in the literature through a meta-analytic review of 66 empirical studies, representing 106 ethics courses and 10,069 participants. The frequency and effectiveness of 67 instructional and process-based content areas were also assessed for each delivery format. Process-based contents were best delivered face-to-face, whereas contents delivered online (...) were most effective when restricted to compliance-based instructional contents. Overall, hybrid courses were found to be most effective, suggesting that ethics courses are best delivered using a blend of formats and content areas. Implications and recommendations for future development of ethics education courses in the sciences are discussed. (shrink)

ABSTRACT Research examining ethical decision-making has focused on how people engage in EDM, leading many researchers to focus on sensemaking models of EDM. Although the merits of a sensemaking approach with respect to EDM are evident in the literature, less is known about the specific cognitive processes by which sensemaking impacts EDM. This study examines the impact of three late-cycle cognitive processes – idea generation, evaluation, and revision – as well as the timing of these processes on EDM. Results indicate (...) that information gathering early on is critical to EDM; a finding which supports an active sensemaking model over an intuitive one. (shrink)

What makes it true when we say that something is not the case? Truthmaker maximalists think that every truth has a truthmaker—some fact in the world—that makes it true. No such facts can be found for the socalled negative truths. If a proposition is true when it has a truthmaker, then it would be false when it has no truthmaker. I therefore argue that negative truths, such as t<p>, are best understood as falsehoods, f<p>.

The topic of fake news has received increased attention from philosophers since the term became a favorite of politicians (Habgood-Coote 2016; Dentith 2016). Notably missing from the conversation, however, is a discussion of fake news and conspiracy theory media as a market. This paper will take as its starting point the account of noxious markets put forward by Debra Satz (2010), and will argue that there is a pro tanto moral reason to restrict the market for fake news. Specifically, we (...) begin with Satz’s argument that restricting a market may be required when i) that market inhibits citizens from being able to stand in an equal relationship with one another, and ii) this problem cannot be solved without such direct restrictions. Our own argument then proceeds in three parts: first, we argue that the market for fake news fits Satz’s description of a noxious market; second, we argue against explanations of the proliferation of fake news that are couched in terms of “epistemic vice”, and likewise argue against prescribing critical thinking education as a solution to the problem; finally, we conclude that, in the absence of other solutions to mitigate the noxious effects of the fake news market, we have a pro tanto moral reason to impose restrictions on this market. At the end of the paper, we consider one proposal to regulate the fake news market, which involves making social media outlets potentially liable in civil court for damages caused by the fake news hosted on their websites.

Moral distress has been characterised in the nursing literature as a major problem affecting nurses in all healthcare systems. It has been portrayed as threatening the integrity of nurses and ultimately the quality of patient care. However, nursing discourse on moral distress is not without controversy. The notion itself is conceptually flawed and suffers from both theoretical and practical difficulties. Nursing research investigating moral distress is also problematic on account of being methodologically weak and disparate. Moreover, the ultimate purpose and (...) significance of the research is unclear. In light of these considerations, it is contended that the notion of moral distress ought to be abandoned and that concerted attention be given to advancing inquiries that are more conducive to improving the quality and safety of moral decision-making, moral conduct and moral outcomes in nursing and healthcare domains.

I argue that propaganda does not characteristically interfere with individual rationality, but instead with group agency. Whereas it is often claimed that propaganda involves some sort of incitement to irrationality, I show that this is neither necessary nor sufficient for a case’s being one or propaganda. For instance, some propaganda constitutes evidence of the speaker’s power, or else of the risk and futility of opposing them, and there is nothing irrational about taking such evidence seriously. I outline an alternative account (...) of propaganda inspired by Hannah Arendt, on which propaganda characteristically creates or destroys group agency. One aspiring to control the public should have an interest in both creating and suppressing group agency, I argue, both because groups have capacities that individuals don’t, and because participation in group action can have a transformative effect upon the individual. Finally, I suggest that my characterization of propaganda suggests a vision of resistance to propaganda quite unlike the one that emerges from irrational-belief accounts, on which propaganda cannot be resisted by oneself.

This article explores a theoretical legacy that underpins the ways in which many social scientists come to know and understand obesity. In attempting to distance itself from essentialist discourses, it is not surprising that this literature focuses on the discursive construction of fat bodies rather than the materiality or agency of bodily matter. Ironically, in developing arguments that only critique representations of obesity or fat bodies, social science scholars have maintained and reproduced a central dichotomy of Cartesian thinking – that (...) between social construction and biology. In this article I examine the limitations of social constructionist arguments in obesity/critical fat studies and the implications for ignoring materiality. Through bringing together the theoretical insights of material feminism and obesity science’s attention to maternal nutrition and the fetal origins hypothesis, this article moves beyond the current philosophical impasse, and repositions biological and social constructionist approaches to obesity not as mutually exclusive, but as one of constant interplay and connectedness.

Recent scholarship in intellectual humility (IH) has attempted to provide deeper understanding of the virtue as personality trait and its impact on an individual's thoughts, beliefs, and actions. A limitations-owning perspective of IH focuses on a proper recognition of the impact of intellectual limitations and a motivation to overcome them, placing it as the mean between intellectual arrogance and intellectual servility. We developed the Limitations-Owning Intellectual Humility Scale to assess this conception of IH with related personality constructs. In Studies 1 (...) (n= 386) and 2 (n = 296), principal factor and confirmatory factor analyses revealed a three-factor model – owning one's intellectual limitations, appropriate discomfort with intellectual limitations, and love of learning. Study 3 (n = 322) demonstrated strong test-retest reliability of the measure over 5 months, while Study 4 (n = 612) revealed limitations-owning IH correlated negatively with dogmatism, closed-mindedness, and hubristic pride and positively with openness, assertiveness, authentic pride. It also predicted openness and closed-mindedness over and above education, social desirability, and other measures of IH. The limitations-owning understanding of IH and scale allow for a more nuanced, spectrum interpretation and measurement of the virtue, which directs future study inside and outside of psychology.

Dynamic Consent is both a model and a specific web-based tool that enables clear, granular communication and recording of participant consent choices over time. The DC model enables individuals to know and to decide how personal research information is being used and provides a way in which to exercise legal rights provided in privacy and data protection law. The DC tool is flexible and responsive, enabling legal and ethical requirements in research data sharing to be met and for online health (...) information to be maintained. DC has been used in rare diseases and genomics, to enable people to control and express their preferences regarding their own data. However, DC has never been explored in relationship to historical collections of bioscientific and genetic heritage or to contexts involving Aboriginal and Torres Strait Islander people.In response to the growing interest by First Peoples throughout Australia in genetic and genomic research, and the increasing number of invitations from researchers to participate in community health and wellbeing projects, this article examines the legal and ethical attributes and challenges of DC in these contexts. It also explores opportunities for including First Peoples' cultural perspectives, governance, and leadership as a method for defining DC on cultural terms that engage best practice research and data analysis as well as respect for meaningful and longitudinal individual and family participation.

This paper provides an analysis of U.S. farmland owners, operators, and workers by race, ethnicity, and gender. We first review the intersection between racialized and gendered capitalism and farmland ownership and farming in the United States. Then we analyze data from the 2014 Tenure and Ownership Agricultural Land survey, the 2012 Census of Agriculture, and the 2013–2014 National Agricultural Worker Survey to demonstrate that significant nation-wide disparities in farming by race, ethnicity and gender persist in the U.S. In 2012–2014, White (...) people owned 98% and operated 94% of all farmland. They generated 98% of all farm-related income from land ownership and 97% of income from farm owner-operatorship. Meanwhile, People of Color farmers were more likely to be tenants rather than owners, owned less land, and generated less farm-related wealth per person than their White counterparts. Hispanic farmers were also disproportionately farm laborers. In addition to racial and ethnic disparities, there were disparities by gender. About 63% of non-operating landowners, 86% of farm operators, and 87% of tenant farmers were male, and female farmers tended to generate less income per farmer than men. This data provides evidence of ongoing racial, ethnic and gender disparities in agriculture in the United States. We conclude with a call to address the structural drivers of the disparities and with recommendations for better data collection. (shrink)

This article examines the issues that are at stake in the current resurgence of interest in the subject of habit. We focus on the role that habit has played in conceptions of the relations between body and society, and the respects in which such conceptions have been implicated in processes of governance. We argue that habit has typically constituted a point of leverage for regulatory practices that seek to effect some realignment of the relations between different components of personhood – (...) will, character, memory and instinct, for example – in order to bring about a specific end. In reviewing its functioning in this regard across a range of modern disciplines – philosophy, psychology, sociology – we explore the tensions between its use and interpretation in different lineages: in particular, the Cartesian–Kantian/ravaisson–bergson–deleuze lineages. The article then identifies how these questions are addressed across the contributions collected in this special issue. (shrink)

According to many accounts, propaganda is a variety of politically significant signal with a distinctive connection to irrationality. This irrationality may be theoretical, or practical; it may be supposed that propaganda characteristically elicits this irrationality anew, or else that it exploits its prior existence. The view that encompasses such accounts we will call irrationalism. This essay presents two classes of propaganda that do not bear the sort of connection to irrationality posited by the irrationalist: hard propaganda and propaganda by the (...) deed. Faced with these counterexamples, some irrationalists will offer their account of propaganda as a refinement of the folk concept rather than as an attempt to capture all of its applications. The author argues that any refinement of the concept of propaganda must allow the concept to remain essentially political, and that the irrationalist refinement fails to meet this condition.

For much of their history, the relationship between anthropology and psychology has been well captured by Robert Frost's poem, “Mending Wall,” which ends with the ironic line, “good fences make good neighbors.” The congenial fence was that anthropology studied what people think and psychology studied how people think. Recent research, however, shows that content and process cannot be neatly segregated, because cultural differences in what people think affect how people think. To achieve a deeper understanding of the relation between process (...) and content, research must integrate the methodological insights from both anthropology and psychology. We review previous research and describe new studies in the domain of folk biology which examine the cognitive consequences of different conceptualizations of nature and the place of humans within it. The focus is on cultural differences in framework theories among Native Americans and European American children and adults living in close proximity in rural Wisconsin. Our results show that epistemological orientations affect memory organization, ecological reasoning, and the perceived role of humans in nature. This research also demonstrates that cultural differences in framework theories have implications for understanding intergroup conflict over natural resources and are relevant to efforts to improve science learning, especially among Native American children.

In this study we use dual process theory of self-regulation to develop a framework that outlines the mediating and moderating mechanisms explaining the relationship between leader emotional exhaustion and leadership style (transformational leadership and abusive supervision). Using Glomb et al.’s (2011) framework, we identify empathy and negative emotion as mediators that are of particular importance for leaders. In addition, we propose that leader mindfulness moderates these processes to improve leadership style. Using a time-lagged survey of leaders (N = 505) we (...) found that leader empathy and negative emotion mediated the relationships between emotional exhaustion and leadership style. Furthermore, we found that leader mindfulness significantly moderated the indirect effect of leader emotional exhaustion on leadership style through negative emotion. However, leader mindfulness did not moderate the relationship between emotional exhaustion and empathy. Theoretical and practical implications are discussed. (shrink)

The field of science communication is plagued by challenges. Communicators face the difficulty of responding to unjustified public skepticism over issues like climate change and COVID-19 while also acknowledging the fallibility and limitations of scientific knowledge. Our goal in this paper is to suggest a new model for science communication that can help foster more productive, respectful relationships among all those involved in science communication. Inspired by the pragmatist philosophy of John Dewey, we develop an experience model, according to which (...) science communication consists in people’s experiences with science and the meanings they develop from those experiences. Three principles are central to the model: experience is cumulative, context matters, and audiences have agency. We argue that this model has significant implications both for communication research and practice, which we illustrate by applying it to the phenomenon of vaccine hesitancy. We show how science communicators can help to identify and alleviate structural factors that contribute to skepticism as well as fostering opportunities for meaning making around shared experiences.

Persons with dementia often prefer to participate in decisions about their health care, but may be prevented from doing so because healthcare decision-making law facilitates use of advance directives or surrogate decision makers for persons with decisional impairments such as dementia. Federal and state disability law provide alternative decision-making models that do not prevent persons with mild to moderate dementia from making their own healthcare decisions at the time the decision needs to be made. In order to better promote autonomy (...) and wellbeing, persons with dementia should be accommodated and supported so they can make their own healthcare decisions. (shrink)

This paper takes up the question of how videographic public announcements (VPAs)---i.e. videos that a wide swath of the public sees and knows that everyone else can see too--- have functioned to mobilize people politically, and how the presence of deepfakes in our information environment stands to change the dynamics of this mobilization. Existing work by Regina Rini, Don Fallis and others has focused on the ways that deepfakes might interrupt our acquisition of first-order knowledge through videos. But I point (...) out that even where every audience member takes a video to be veridical, where first-order knowledge acquisition is secure, an audience aware of deepfakes in their environment will not acquire higher order knowledge in the way that has erstwhile been characteristic for audiences of VPAs. Engaging with ideas from the literatures on public announcement logic, common knowledge, and convention, I enumerate a variety of ways in which we should expect this absence of higher order knowledge to throw up barriers to political mobilization. I go on to apply my analysis of VPAs to the mechanisms by which an uptick in publicly available videos of police brutality over the last decade, mediated by camera phones and social media, was responsible for the largest mass protests in US history in summer 2020. This makes vivid the stakes of the transformation in our mobilizing environment that I've claimed deepfakes effect: where we lose the common-knowledge-generating effects of VPAs, there are fresh obstacles to this sort of mass mobilization.

Here are two widely held positions on the ethics of dating: First, people are generally morally justified in excluding people they don’t find attractive from their dating pool. Second, people are not justified in maintaining a dating pool that is racially exclusive, even on grounds like attraction. In this paper, we demonstrate how these positions are consistent. To do so we differentiate our attitudes in dating and our dating behavior. Then we show how existing criticisms of racialized attitudes in dating (...) are incomplete as practical criticisms of our behavior. Finally, we give our account of the moral reasons whites have to change their dating preferences when they exclude people of color. In doing so, we supplement existing discussions of race-based discrimination in dating. (shrink)

Developmental origins of health and disease and epigenetics have expanded understanding of how the environment affects the health of women before and during pregnancy—with lifelong health consequences for the fetus. This has translated to a narrow focus on women’s lifestyle during pregnancy, especially for women classified as obese. In this study, we show that psychosocial harms such as distress or shame felt by pregnant women are rarely countenanced in these endeavors. To demonstrate this, we examine published documents about a large (...) set of trials of lifestyle interventions united through an international consortium. Yet there is now a literature in which pregnant women with large bodies report feeling humiliated and a wider literature on the stigma of obesity. We argue that shame is produced and reproduced through the discursive and material knowledge-making scientific practices of DOHaD translation. Interventions that intensify the shame of large body size in pregnancy may be stressful, and neurophysiological stress pathways are well-known within DOHaD to have consequences for fetal development, so these interventions potentially undermine the very processes they set out to protect. A feminist response may protect women from shame and redirect attention to the social and structural determinants of health. (shrink)

According to a recent survey by the HR Research Institute, as the presence of artificial intelligence (AI) becomes increasingly common in the workplace, HR professionals are worried that the use of recruitment algorithms will lead to a “dehumanization” of the hiring process. Our main goals in this paper are threefold: i) to bring attention to this neglected issue, ii) to clarify what exactly this concern about dehumanization might amount to, and iii) to sketch an argument for why dehumanizing the hiring (...) process is ethically suspect. After distinguishing the use of the term “dehumanization” in this context (i.e., removing the human presence) from its more common meaning in the interdisciplinary field of dehumanization studies (i.e., conceiving of other humans as subhuman), we argue that the use of hiring algorithms may negatively impact the employee-employer relationship. We argue that there are good independent reasons to accept a substantive employee-employer relationship, as well as an applicant-employer relationship, both of which are consistent with a stakeholder theory of corporate obligations. We further argue that dehumanizing the hiring process may negatively impact these relationships because of the difference between the values of human recruiters and the values embedded in recruitment algorithms. Drawing on Nguyen’s (2021) critique of how Twitter “gamifies communication”, we argue that replacing human recruiters with algorithms imports artificial values into the hiring process. We close by briefly considering some ways to potentially mitigate the problems posed by recruitment algorithms, along with the possibility that some difficult trade-offs will need to be made.

Reductionism is a central issue in the philosophy of biology. One common objection to reduction is that molecular explanation requires reference to higher-level properties, which I refer to as the context objection. I respond to this objection by arguing that a well-articulated notion of a mechanism and what I term mechanism extension enables one to accommodate the context-dependence of biological processes within a reductive explanation. The existence of emergent features in the context could be raised as an objection to the (...) possibility of reduction via this strategy. I argue that this objection can be overcome by showing that there is no tenable argument for the existence of emergent properties that are not susceptible to a reductive explanation. (shrink)

To address climate change fairly, many conflicting claims over natural resources must be balanced against one another. This has long been obvious in the case of fossil fuels and greenhouse gas sinks including the atmosphere and forests; but it is ever more apparent that responses to climate change also threaten to spur new competition over land and extractive resources. This makes climate change an instance of a broader, more enduring and - for many - all too familiar problem: the problem (...) of human conflict over how the natural world should be cared for, protected, shared, used, and managed. -/- This work develops a new theory of global egalitarianism concerning natural resources, rejecting both permanent sovereignty and equal division, which is then used to examine the problem of climate change. It formulates principles of resource right designed to protect the ability of all human beings to satisfy their basic needs as members of self-determining political communities, where it is understood that the genuine exercise of collective self-determination is not possible from a position of significant disadvantage in global wealth and power relations. These principles are used to address the question of where to set the ceiling on future greenhouse gas emissions and how to share the resulting emissions budget, in the face of conflicting claims to fossil fuels, climate sinks, and land. It is also used to defend an unorthodox understanding of responsibility for climate change as a problem of global justice, based on its provenance in historical injustice concerning natural resources.

Causation is everywhere in the world: it features in every science and technology. But how much do we understand it? Mumford and Anjum develop a new theory of causation based on an ontology of real powers or dispositions.

A key feature of unregulated mHealth research is the diversity of participants in this space. Applying an approach drawn from user experience design, we describe a set of archetypal unregulated mHealth researcher “personas,” which range from individuals who seek empowerment or have philanthropic objectives to those who are primarily motivated by financial gain or have misanthropic objectives. These descriptions are useful for evaluating policies applicable to mHealth to understand how they will impact various stakeholders.

SUMMARYContemporary scholars seeking to advance the study of political phenomena identify their inquiry as a ‘science' that attains success through rigorous method. Thus the ‘methodological anarchism' of Paul Feyerabend's philosophy of science might seem an inauspicious place to find a fruitful disciplinary vision. Nonetheless, it echoes a longstanding conception of the ‘science' of politics articulated by Niccolò Machiavelli. Looking to Feyerabend, we propose to surmount the impasse between Machiavelli's account of politics and the demands of modern science and recover his (...) contribution to the scientific study of politics. In doing so, Machiavelli illustrates the potential of a Feyerabendian political science. (shrink)

Some claim that a commitment to egalitarianism is in tension with support for reparations for historical injustice. This tension appears to arise insofar as egalitarianism is a forward-looking approach to justice: an approach that tells us what kind of world we should aim to build, where that world is not defined in terms of the decisions or actions of previous generations. Some have claimed that egalitarianism thereby renders reparations redundant. One popular option for egalitarians who aim to reject this thesis (...) is to insist that historical injustices demand reparations when they have caused present-day inequality. A promising alternative, skilfully defended by Alasia Nuti in Injustice and the Reproduction of History, is to argue that historical injustices stand in need of repair when they are reproduced into the present-day, such that some past and present injustices are in fact the same injustice. In this paper, I assess these egalitarian responses to the redundancy thesis. I find that Nuti’s account is equipped to reject this thesis, but that the same lines of reply can be adopted by proponents of the causal approach. I suggest that both approaches therefore be viewed as potential ways to conceptualise the relationship between historical injustice and our present normative circumstances; and that in choosing between them, we should understand ourselves to be engaged in an ameliorative project – a project that is guided by, and designed to help us to achieve, our legitimate purposes.

Generative artificial intelligence has given us synthetic media that are increasingly easy to create and increasingly hard to distinguish from photographs and videos. Whereas an existing literature has been concerned with how these new media might make a difference for would-be knowers—the viewers of photographs and videos—I advance a thesis about how they will make a difference for would-be communicators—those who embed photos and videos in their speech acts. I claim that the presence of these media in our information environment (...) reduces our ability to show one another things, even as it may increase our resources for telling. And I argue that this has consequences beyond the disruption of knowledge acquisition; showing is a way that we preserve relational equality through superficial asymmetries in political communication, and thereby express respect for our audiences. If synthetic media reduce our options for showing, they then interfere in the way that we manage our relationships in the context of collective political action. (shrink)

In this paper I aim to make sense of our pre‐theoretic intuitions about dispositions by presenting an argument for the identity of a disposition with its putative categorical base. The various possible ontologies for dispositions are outlined. The possibility of an empirical proof of identity is dismissed. Instead an a priori argument for identity is adapted from arguments in the philosophy of mind. I argue that dispositions occupy, by analytic necessity, the same causal roles that categorical bases occupy contingently and (...) that properties with identical causal roles are identical. The validity of the argument depends upon the possibility of overdetermination of disposition manifestations being rejected. ‘Ungrounded dispositions’ are dismissed as not genuine dispositions. Identity conditions for dispositions and categorical bases are outlined. (shrink)
