Rapid advances in neuroscience may enable us to identify the neural correlates of ordinary decision making. Such knowledge opens up the possibility of acquiring highly accurate information about people’s competence to consent to medical procedures and to participate in medical research. Currently we are unable to determine competence to consent with accuracy and we make a number of unrealistic practical assumptions to deal with our ignorance. Here I argue that if we are able to detect competence to consent and if (...) we are able to develop a reliable neural test of competence to consent, then these assumptions will have to be rejected. I also consider and reject three lines of argument that might be developed by a defender of the status quo in order to protect our current practices regarding judgments of competence in the face of the availability of information about the neural correlates of ordinary human decision making.

Liberalism welcomes diversity in substantive ideas of the good but not in the process whereby these ideas are formed. Ideas of the good acquire weight on the presumption that each is a person's own, formed independently. But people differ in their capacities to conceptualize. Some, appropriately characterized as cerebral, are proficient in and profoundly involved with conceptualizing. Others, labeled cognitively disabled, range from individuals with mild limitations to those so unable to express themselves that we cannot be sure whether their (...) behavior is mediated by concepts at all. Constricted cognitive capacities have been thought to prevent participation in the prescribed process for forming personalized ideas of the good. So liberal theory, when formulating principles and practices of justice, often disregards cognitively disabled peoples' perspectives. We put aside metaphysically driven notions about personhood and show how interpersonal processes of “prosthetic” thinking (different from surrogacy) can satisfy liberalism's standards, positioning cognitively disabled individuals as fully participating subjects of justice.

Heated debate surrounds the question whether the relationship between physician-researcher and patient-subject is governed by a duty of care. Miller and Weijer argue that fiduciary law provides a strong legal foundation for this duty, and for articulating the terms of the relationship between physician-researcher and patient-subject.

In many Western jurisdictions, the law presumes that adult persons, and sometimes children that meet certain criteria, are capable of making their own health care decisions; for example, consenting to a particular medical treatment, or consenting to participate in a research trial. But what exactly does it mean to say that a subject has or lacks the requisite capacity to decide? This last question has to do with what is commonly called “decisional capacity,” a central concept in health care law (...) and ethics, and increasingly an independent topic of philosophical inquiry.

Limits to paternalism are, in the liberal democracies, partially defined by the concepts of decision-making capacity/incapacity (mental competence/incompetence). The paper is a response to Ian Wilkss (1997) recent attempt to defend the idea that the standards for decisional capacity ought to vary with the degree of risk incurred by certain choices. Wilkss defense is based on a direct appeal to the logical features of examples and analogies, thus attempting to by-pass earlier criticisms (e.g., Culver Gert, 1990) of risk-based standards. Wilkss (...) argument is found wanting on the grounds that he misconstrues the logic of such capacity, especially in accounting for conceptual and pragmatic ties with issues of decisional authority. A diagnosis is offered as to the source of Wilkss error (the assumption that mental competence is a species of wider genus of competence), and an alternative way of accounting for risk within the predominant contemporary legal framework is sketched.

Mental competence, or decision‐making capacity, is an important concept in law, psychiatry, and bioethics. A major problem faced in the development and implementation of standards for assessing mental competence is the issue of objectivity. The problem is that objective standards are hard to formulate and apply. The aim here is to review the limited philosophical literature on the place of value in competence in an attempt to introduce the issues to a wider audience. The thesis that the assessment of competence (...) must incorporate elements of value and rationality is defended, and some tentative suggestions offered about how this might be achieved in a clinical setting.

Book reviewed in this article: Principles of Biomedical Ethics. By Tom L. Beauchamp and James F. Childress.

Abstract:The ethical principle of autonomy requires physicians to respect patient autonomy when present, and to protect the patient who lacks autonomy. Fulfilling this ethical obligation when a patient has a communication impairment presents considerable challenges. Standard methods for evaluating decision-making capacity require a semistructured interview. Some patients with communication impairments are unable to engage in a semistructured interview and are at risk of the wrongful loss of autonomy. In this article, we present a general strategy for assessing decision-making capacity in (...) patients with communication impairments. We derive this strategy by reflecting on a particular case. The strategy involves three steps: (1) determining the reliability of communication, (2) widening the bandwidth of communication, and (3) using compensatory measures of decision-making capacity. We argue that this strategy may be useful for assessing decision-making capacity and preserving autonomy in some patients with communication impairments. (shrink)

This paper examines the moral import of a distinction between natural and social inequalities. Following Thomas Nagel, it argues for a “denatured” distinction that relies less on the biological vs. social causation of inequalities than on the idea that society is morally responsible for some inequalities but not others. It maintains that securing fair equality of opportunity by eliminating such social inequalities has particularly high priority in distributive justice. Departing from Nagel, it argues that society can be responsible for inequalities (...) not only when they are the unintended result of justifiable projects, but even when their alleviation would be very costly. Sharing Nagel’s general concept of ‘social inequality’, then, this paper proposes a far more expansive conception. We argue that many disadvantages due to disability fall under this conception. Eliminating or alleviating those disadvantages should be regarded as securing fair equality of opportunity, not improving the condition of the worst-off. (shrink)

With the waves of reform occurring in mental health legislation in England and other jurisdictions, mental capacity is set to become a key medico-legal concept. The concept is central to the law of informed consent and is closely aligned to the philosophical concept of autonomy. It is also closely related to mental disorder. This paper explores the interdisciplinary terrain where mental capacity is located. Our aim is to identify core dilemmas and to suggest pathways for future interdisciplinary research. The terrain (...) can be separated into three types of discussion: philosophical, legal and psychiatric. Each discussion approaches mental capacity and judgmental autonomy from a different perspective yet each discussion struggles over two key dilemmas: whether mental capacity and autonomy is/should be a moral or a psychological notion and whether rationality is the key constitutive factor. We suggest that further theoretical work will have to be interdisciplinary and that this work offers an opportunity for the law to enrich its interpretation of mental capacity, for psychiatry to clarify the normative elements latent in its concepts and for philosophy to advance understanding of autonomy through the study of decisional dysfunction. The new pressures on medical and legal practice to be more explicit about mental capacity make this work a priority. (shrink)

Bioethics is currently witnessing unprecedented debate over the moral and legal norms governing the conduct of clinical research. At the center of this debate is the duty of care in clinical research, and its most widely accepted specification, clinical equipoise. In recent work, we have argued that equipoise and cognate concepts central to the ethics of clinical research have been left unnecessarily vulnerable to criticism. We have suggested that the vulnerability lies in the conspicuous absence of an articulated foundation in (...) moral and legal theory of the physician-researcher's duty of care to the patient-subject. We have repeatedly suggested that the requisite foundation is in the ethics of trust and the law of fiduciaries.Curiously, despite the absence of a published thorough exposition of our position, some have preemptively criticized our suggestion that the relationship between physician-researcher and patient-subject is fiduciary. Others have offered their own accounts of the implications of fiduciary law for the relationship. (shrink)

This paper explores the ethical and conceptual implications of the findings from an empirical study (reported elsewhere) of decision-making capacity in anorexia nervosa. In the study, ten female patients aged thirteen to twenty-one years with a diagnosis of anorexia nervosa, and eight sets of parents, took part in semistructured interviews. The purpose of the interviews was to identify aspects of thinking that might be relevant to the issue of competence to refuse treatment. All the patient-participants were also tested using the (...) MacArthur Competence Assessment Tool—Treatment test of competence. This is a formalized, structured, interviewer-administered test of competence, which is a widely accepted clinical tool for determining capacity. The young women also completed five brief, self-administered questionnaires to assess their levels of psychopathology. The issues identified from the interviews are described under two headings: difficulties with thought processing and changes in values. The results suggest that competence to refuse treatment may be compromised in people with anorexia nervosa in ways that are not captured by traditional legal approaches. (shrink)
