The meanings of abstract concepts depend on context. Perceptual symbol systems (PSS) provide a powerful framework for representing such context. Whereas a few expected difficulties for simulations are consistent with empirical findings, the theory does not clearly predict simulations of specific abstract concepts in a testable way and does not appear to distinguish abstract noun concepts (like truth) from their stem concepts (such as true).

Schyns, Goldstone & Thibaut present reasonable arguments for feature creation in category learning. We argue, however, that they do not provide unequivocal evidence either for the necessity or for the occurrence of feature creation. In an effort to sharpen the debate, we take the stand that a fixed feature approach is to be preferred in the absence of compelling evidence.

After surveying and criticizing some earlier definitions of "disease", we propose that a general term--malady--be used to represent what all diseases, illnesses, injuries, etc., have in common. We define a malady as the suffering, or increased risk of suffering an evil in the absence of a distinct sustaining cause. We discuss the key terms in the definition: evil, distinct sustaining cause, and increased risk. We show that the role of abnormality is to clarify these terms rather than to be used (...) directly in the definition of malady. (shrink)

Legal precedent, professional‐society statements, and even many medical ethicists agree that some situations may call for a clinician to engage in an act of lying or nonlying deception of a patient or patient's family member. Still, the moral terrain of clinical deception is largely uncharted, and when it comes to practical guidance for clinicians, many might think that ethicists offer nothing more than the rule never to deceive. This guidance is insufficient to meet the real‐world demands of clinical practice, and (...) this article endeavors to articulate a framework to help clinicians better navigate the ethics of clinical deceit. The framework articulates four morally relevant dimensions of a potential deceptive act that should be examined to better determine the moral justification that might be required: the target of the act, the nature of the information, the nature of the act, and the context of the act.

Neuroscientists have long sought to study the dynamic activity of the human brain—what's happening in the brain, that is, while people are thinking, feeling, and acting. Ideally, an inside look at brain function would simultaneously and continuously measure the biochemical state of every cell in the central nervous system. While such a miraculous method is science fiction, a century of progress in neuroimaging technologies has made such simultaneous and continuous measurement a plausible fiction. Despite this progress, practitioners of modern neuroimaging (...) struggle with two kinds of limitations: those that attend the particular neuroimaging methods we have today and those that would limit any method of imaging neural activity, no matter how powerful.In this essay, I consider the liabilities and potential of techniques that measure human brain activity. I am concerned here only with methods that measure relevant physiologic states of the central nervous system and relate those measures to particular mental states. I will consider in particular the preeminent method of functional neuroimaging: BOLD fMRI. While there are several practical limits on the biological information that current technologies can measure, these limits—as important as they are—are minor in comparison to the fundamental logical restraints on the conclusions that can be drawn from brain imaging studies.

The men and women who serve in the armed forces, in the words of Major General Joseph Caravalho, “sign a blank check, co-signed by their families, payable to the Army, Navy, Air Force, or Marines, up to and including their lives.” It is human nature to consider such a pact in polarized terms; the pact concludes in either a celebratory homecoming or funereal mourning. But in reality, surviving catastrophic injury may incur the greatest debt. The small but real possibility of (...) losing the ability to bear biological children due to genitourinary combat injury has been a topic of discussion in hushed tones, behind closed doors. But as policy changes move the conversation into the open, we must be fully aware of the far-reaching and long-term impacts of decisions on those who have sustained genitourinary injury. In January 2016, Secretary of Defense Ashton Carter outlined a set of reforms that would improve the quality of life for military families by recognizing the importance of maintaining fertility, even in the face of severe injury. This first promising step could build a solid foundation of insuring fertility preservation for wounded service members with genitourinary injury, and it could set a precedent beyond the military for insuring treatment for people who have lost their reproductive capacity. Thus, the ethical challenges raised by the new policy require careful analysis. (shrink)

The ethical tensions inherent in all Baby Doe treatment decisions are compounded by medical uncertainty. Physicians both here and abroad have adopted various strategies. Swedish doctors tend to withhold treatment from the beginning from infants for whom statistical data suggest a grim prognosis. The British are more likely to initiate treatment but withdraw it if the infant appears likely to die or suffer severe brain damage. The trend in the U.S. is to start treating any baby who is potentially viable (...) and continue until it is virtually certain that the infant will die. The “least worst” strategy is an individualized one: starting treatment gathering data, and then reassessing the decision. (shrink)

In their report in this supplement on research regulatory systems, Barbara Bierer and Mark Barnes note that, when research misconduct has been detected but not yet proven, the individual with institutional responsibility for oversight of research misconduct investigations “may determine that notification of relevant journals or professional societies and correction or full retraction of implicated papers or presentations is appropriate. In those cases, even when a finding of research misconduct per se has not been made or has not been explicitly (...) stated, the journal, professional society, and their readers or members may draw their own conclusions as to what led to the retraction or correction.” This statement highlights an aspect of the reviewed regulatory schemes that creates vulnerability for institutions of higher education subject to the regulations: while, as the authors suggest, it may be “appropriate” to notify third parties (that is, journals, professional societies, and other academic institutions) of suspected research misconduct, there is no regulatory obligation to provide such a notification, and, in fact, providing early (or any) notification is contrary to the confidentiality provisions of the research misconduct regulations. Moreover, the institution—and individuals acting on behalf of the institution—may face legal exposure for notifying outside entities. (shrink)

Much new global genetic research employs whole genome sequencing, which provides researchers with large amounts of data. The quantity of data has led to the generation and discovery of more incidental or secondary findings and to vigorous theoretical discussions about the ethical obligations that follow from these incidental findings. After a decade of debate in the genetic research community, there is a growing consensus that researchers should, at the very least, offer to return incidental findings that provide high‐impact, medically relevant (...) information, when it is not unduly burdensome to the research enterprise to do so. Much as genetic research has been limited to U.S. and European settings, the incidental findings debate has primarily focused on research conducted in high‐income countries. In a 2015 paper, Alberto Ortiz‐Osorno, Linda Ehler, and Judith Brooks note salient differences between the circumstances of research participants in low‐ and high‐resource settings that alter the analysis of when and why incidental findings should be offered to research participants. In this article, we expand on their analysis and present a framework for thinking about how investigators’ obligations to return genomic data might change in low‐resource settings, particularly in settings where participants do not have access to the medical care needed to treat, assess, or monitor incidental findings that are actionable in settings with plentiful resources.

The release of genetically engineered organisms into the shared environment raises scientific, ethical, and societal issues. Using some form of democratic deliberation to provide the public with a voice on the policies that govern these technologies is important, but there has not been enough attention to how we should connect public deliberation to the existing regulatory process. Drawing on lessons from previous public deliberative efforts by U.S. federal agencies, we identify several practical issues that will need to be addressed if (...) relevant federal agencies are to undertake public deliberative activities to inform decision‐making about gene editing in the wild. We argue that, while agencies may have institutional capacity to undertake public deliberative activities, there may not be sufficient political support for them to do so. Advocates of public deliberation need to make a stronger case to Congress about why federal agencies should be encouraged and supported to conduct public deliberations. (shrink)

Whether adolescents should be allowed to make their own medical decisions has been a topic of discussion in bioethics for at least two decades now. Are adolescents sufficiently capacitated to make their own medical decisions? Is the mature-minor doctrine, an uncommon legal exception to the rule of parental decision-making authority, something we should expand or eliminate? Bioethicists have dealt with the curious liminality of adolescents—their being neither children nor adults—in a variety of ways. However, recently there has been a trend (...) to rely heavily, and often exclusively, on emerging neuroscientific and psychological data to answer these questions. Using data from magnetic resonance imaging and functional MRI studies on the adolescent brain, authors have argued both that the adolescent brain isn't sufficiently mature to broadly confer capacity on this population and that the adolescent brain is sufficiently mature to assume adolescent capacity. Scholars then accept these data as sufficient for concluding that adolescents should or should not have decision-making authority. Two critical mistakes are being made here. The first is the expectation that neuroscience or psychology is or will be able to answer all our questions about capacity. The second, and more concerning, mistake is the conflation of decision-making capacity with decision-making authority. (shrink)

In this issue, Alex London and Kevin Zollman provide an analysis of an influential approach to the ethics of international research, known as the “fair benefits” approach. According to them, the fair benefits approach suffers from a fatal flaw: it is either too vague to be useful, or worse, is internally inconsistent. The fair benefits approach was developed based on a presentation I gave at a workshop organized in Malawi in March 2001 by the National Institutes of Health Clinical Center’s (...) Department of Bioethics. In this presentation, I made what I still think is a valid point, which was accepted by the diverse group of participants and formed the basis of the subsequent publications: One should not ..

Brain death, or the determination of death by neurological criteria, has been described as a legal fiction. Legal fictions are devices by which the law treats two analogous things (in this case, biological death and brain death) in the same way so that the law developed for one can also cover the other. Some scholars argue that brain death should be understood as a fiction for two reasons: the way brain death is determined does not actually satisfy legal criteria requiring (...) the permanent cessation of all brain function, and brain death is not consistent with the biological conception of death as involving the irreversible cessation of the functioning of an organism as a whole. Critics counter that the idea that brain death is a legal fiction is deceptive and undemocratic. I will argue that diagnosing brain death as a hidden legal fiction is a helpful way to understand its historical development and current status. For the legal‐fictions approach to be ethically justifiable, however, the fact that brain death is a legal fiction not aligned with the standard biological conception of death must be acknowledged and made transparent.

Bioethics is reexamining how to implement diversity, equity, inclusion, and justice concerns into scholarship. However, bioethicists should question the categories used to define diversity. The act of categorization is value laden, and classification systems confer power and benefits and generate harms. For example, what conditions count as disabilities? We should consider the equity implications of offering only “male” and “female” options for self‐identification in health records. However, we should also interrogate all ideas about categorization, including how categories are formed, why (...) they are formed, and who decides. Bioethicists cannot comprehend fully what equity and justice mean for underrepresented, underserved, or marginalized people until there is an understanding of how the boundaries of marginalization are created.

Like other science, technology, engineering, and mathematics fields, ecological research needs ethics. Given the rapid pace of technological developments and social change, it is important for scientists to have the vocabulary and critical-thinking skills necessary to identify, analyze, and communicate the ethical issues generated by the research and practices within their fields of specialization. The goal of introducing ethics education for ecological researchers would be to promote a discipline in which scientists are willing and able to engage in ethical questions (...) and problem solving, even if they do so inadequately at first. Practicing ecologists ought to be able to identify and critically evaluate the ethical dimensions of their field studies because ecologists are at the forefront of important interfaces between humans and other-than-human organisms and natural systems. They are among the first to identify the impact of anthropogenic changes to the environments. Rapidly changing local and global environments mean that ecologists will be on the front line of any efforts to create a sustainable lifestyle for humans on this planet. (shrink)

This essay introduces a special report from The Hastings Center entitled Democracy in Crisis: Civic Learning and the Reconstruction of Common Purpose, which grew out of a project supported by the John S. and James L. Knight Foundation. This multiauthored report offers wide‐ranging assessments of increasing polarization and partisanship in American government and politics, and it proposes constructive responses to this in the provision of objective information, institutional reforms in government and the electoral system, and a reexamination of cultural (...) and political values needed if democracy is to function well in a pluralistic and diverse society. The essays in the special report explore the norms of civic learning and institutions, social movements, and communal innovations that can revitalize civic learning in practice. This introductory essay defines and explains the notion of civic learning, which is a lynchpin connecting many of the essays in the report. Civic learning pertains to the ways in which citizens learn about collective social problems and make decisions about them that reflect the duties and responsibilities of citizenship. Such learning can occur in many social settings in everyday life, and it can also be facilitated through participation in the processes of democratic governance on many levels. Civic learning is not doctrinaire and is compatible with a range of public goals and policies. It is an activity that increases what might be called the democratic capability of a people. (shrink)

Many older people need external support for their daily living. A large minority of older adults with low or modest pension incomes face financial strains from the high cost of illness, and many older people in urban areas live in social isolation. Indeed, population aging has become a policy topic of concern. The policy debate since the end of the twentieth century about the future of public pensions and health and long‐term care programs has increasingly framed the growing numbers of (...) older people in alarmist terms. Unfounded claims about the unaffordability and unsustainability of social policies supporting older people have become common currency, often disguised as concerns about intergenerational justice. Such claims and concerns hinder clear thinking about proper social and fiscal policies, housing, health care, and labor markets to safeguard the well‐being of older people in aging societies.

Prescription opioid policies too often reflect over a century's worth of moralizing about the nature of opioid use disorder, the value of pain, and the meaning of suffering. The social and legal penalties to prescribers run in one direction—avoid overprescribing, however defined, at all costs. The lack of shared definitions is problematic for formulating and evaluating opioid policy. For example, the variant definitions of “misuse,” “abuse,” and “addiction” complicate estimates of morbidity. There are also no widely accepted definitions of misprescribing (...) and overprescribing. I offer here a modest attempt at the categorization of misprescribing: inadvertent overprescribing, corrupt overprescribing, qualitative overprescribing, quantitative overprescribing, multiclass overprescribing, and underprescribing.
