First responders to chemical, biological, radiological, or nuclear (CBRN) events face decisions having significant human consequences. Some operational decisions are supported by standard operating procedures, yet these may not suffice for ethical decisions. Responders will be forced to weigh their options, factoring-in contextual peculiarities; they will require guidance on how they can approach novel (indeed unique) ethical problems: they need strategies for “on the spot” ethical decision making. The primary aim of this paper is to examine how first responders should (...) approach on the spot ethical decision-making amid the stress and uncertainty of a CBRN event. Drawing on the long-term professional CBRN experience of one of the authors, this paper sets out a series of practical ethical dilemmas potentially arising in the context of a large-scale chemical incident. We propose a broadly consequentialist approach to on the spot ethical decision-making, but one which incorporates ethical values and rights as “side-constraints”. (shrink)

Engineers must deal with risks and uncertainties as a part of their professional work and, in particular, uncertainties are inherent to engineering models. Models play a central role in engineering. Models often represent an abstract and idealized version of the mathematical properties of a target. Using models, engineers can investigate and acquire understanding of how an object or phenomenon will perform under specified conditions. This paper defines the different stages of the modeling process in engineering, classifies the various sources of (...) uncertainty that arise in each stage, and discusses the categories into which these uncertainties fall. The paper then considers the way uncertainty and modeling are approached in science and the criteria for evaluating scientific hypotheses, in order to highlight the very different criteria appropriate for the development of models and the treatment of the inherent uncertainties in engineering. Finally, the paper puts forward nine guidelines for the treatment of uncertainty in engineering modeling. (shrink)

Standard tools used in societal risk management such as probabilistic risk analysis or cost–benefit analysis typically define risks in terms of only probabilities and consequences and assume a utilitarian approach to ethics that aims to maximize expected utility. The philosopher Carl F. Cranor has argued against this view by devising a list of plausible aspects of the acceptability of risks that points towards a non-consequentialist ethical theory of societal risk management. This paper revisits Cranor’s list to argue that the alternative (...) ethical theory responsibility-catering prioritarianism can accommodate the aspects identified by Cranor and that the elements in the list can be used to inform the details of how to view risks within this theory. An approach towards operationalizing the theory is proposed based on a prioritarian social welfare function that operates on responsibility-adjusted utilities. A responsibility-catering prioritarian ethical approach towards managing risks is a promising alternative to standard tools such as cost–benefit analysis. (shrink)

In the first part of the paper, three objections to the precautionary principle are outlined: the principle requires some account of how to balance risks of significant harms; the principle focuses on action and ignores the costs of inaction; and the principle threatens epistemic anarchy. I argue that these objections may overlook two distinctive features of precautionary thought: a suspicion of the value of “full scientific certainty”; and a desire to distinguish environmental doings from allowings. In Section 2, I argue (...) that any simple distinction between environmental doings and allowings is untenable. However, I argue that the appeal of such a distinction can be captured within a relational account of environmental equity. In Section 3 I show how the proposed account of environmental justice can generate a justification for distinctively “precautionary” policy-making. (shrink)

Is it possible to redress a wrong specifically in one’s capacity as a knower? Epistemic justice has largely been conceived of as either an ideal goal guiding present and future societal endeavours, or a set of ameliorative character virtues. Yet there is also a backward-looking component of epistemic justice, which has so far been neglected. I argue that exercises of our cognitive and epistemic capacities can constitute moral redress for wrong actions and wrongful harms for which we are responsible. Epistemic (...) redress can take non-doxastic forms, but can also involve the formation of new beliefs. Acts of epistemic redress can redress not only epistemic but also non-epistemic wrongs. In the practice of natural science, epistemic redress can play legitimate and necessary roles both within and outside the core procedures of scientific reasoning, without compromising science’s truth-orientated epistemic credentials. When it plays these roles, it can contribute to generating restitutive knowledge. (shrink)

Cost-benefit analysis (CBA) is inappropriate as an aid to Covid policy-making because the plural, incommensurable values at stake are not all amenable to monetary measurement. CBA for Covid policy is also undermined by pervasive uncertainty and ignorance, and has some troubling distributional implications. However, non-consequentialist alternatives to CBA tend towards implausibly absolutist prohibitions on risk imposition. Arguments for setting aside consequentialism for special circumstances (the precautionary principle, or a medical rule of rescue) are also problematic when applied to Covid policy. (...) A broad consequentialist approach to policy guidance is defended, one which does not demand commensuration on a common monetary scale. Despite the absence of commensuration, policy guidance is still possible. (shrink)
