Holm (2022) argues that a class of algorithmic fairness measures, that he refers to as the ‘performance parity criteria’, can be understood as applications of John Broome’s Fairness Principle. We argue that the performance parity criteria cannot be read this way. This is because in the relevant context, the Fairness Principle requires the equalization of actual individuals’ individual-level chances of obtaining some good (such as an accurate prediction from a predictive system), but the performance parity criteria do not guarantee any (...) such thing: the measures merely ensure that certain population-level ratios hold.

Prediction-based decisions, which are often made by utilizing the tools of machine learning, influence nearly all facets of modern life. Ethical concerns about this widespread practice have given rise to the field of fair machine learning and a number of fairness measures, mathematically precise definitions of fairness that purport to determine whether a given prediction-based decision system is fair. Following Reuben Binns (2017), we take ‘fairness’ in this context to be a placeholder for a variety of normative egalitarian considerations. We (...) explore a few fairness measures to suss out their egalitarian roots and evaluate them, both as formalizations of egalitarian ideas and as assertions of what fairness demands of predictive systems. We pay special attention to a recent and popular fairness measure, counterfactual fairness, which holds that a prediction about an individual is fair if it is the same in the actual world and any counterfactual world where the individual belongs to a different demographic group (cf. Kusner et al. (2018)). (shrink)

This article argues that it is far from trivial to convert social science concepts into accurate categories on which algorithms work best. The literature raises this concern in a general way; for example, Deeks notes that legal concepts, such as proportionality, cannot be easily converted into code noting that ‘The meaning and application of these concepts is hotly debated, even among lawyers who share common vocabularies and experiences’ (Deeks in Va Law Rev 104, pp. 1529–1593, 2018). The example discussed here (...) is recidivism prediction, where the factors that are of interest are difficult to capture adequately through questionnaires because survey responses do not necessarily indicate whether the behaviour that is of interest is present. There is room for improvement in how questions are phrased, in the selection of variables, and by encouraging practitioners to consider whether a particular variable is the sort of thing that can be measured by questionnaires at all.

With the increasing use of algorithms in high-stakes areas such as criminal justice and health has come a significant concern about the fairness of prediction-based decision procedures. In this article I argue that a prominent class of mathematically incompatible performance parity criteria can all be understood as applications of John Broome’s account of fairness as the proportional satisfaction of claims. On this interpretation these criteria do not disagree on what it means for an algorithm to be _fair_. Rather they express (...) different understandings of what grounds a claim to a good being allocated by an algorithmic decision procedure. I then argue that an important implication of the Broomean interpretation is that it strengthens the case for outcome-based criteria. Finally, I consider how a version of the levelling-down objection to performance parity criteria arises within the Broomean account. (shrink)

Algorithm-assisted decision procedures—including some of the most high-profile ones, such as COMPAS—have been described as unfair because they compound injustice. The complaint is that in such procedures a decision disadvantaging members of a certain group is based on information reflecting the fact that the members of the group have already been unjustly disadvantaged. I assess this reasoning. First, I distinguish the anti-compounding duty from a related but distinct duty—the proportionality duty—from which at least some of the intuitive appeal of the (...) former illegitimately derives. Second, I distinguish between different versions of the anti-compounding duty, arguing that, on some versions, uses of algorithm-assisted decision procedures rarely clash with the anti-compounding duty. Third, drawing on examples of algorithm-assisted decision procedures, I present three objections to the idea that there is a reason not to compound injustice. The most important of these is that one can compound injustice in a non-disrespectful way, and that the wrongfulness of non-disrespectfully compounding injustice is fully explained by the proportionality duty.

The widespread use of algorithms for prediction-based decisions urges us to consider the question of what it means for a given act or practice to be discriminatory. Building upon work by Kusner and colleagues in the field of machine learning, we propose a counterfactual condition as a necessary requirement on discrimination. To demonstrate the philosophical relevance of the proposed condition, we consider two prominent accounts of discrimination in the recent literature, by Lippert-Rasmussen and Hellman respectively, that do not logically imply (...) our condition and show that they face important objections. Specifically, Lippert-Rasmussen’s definition proves to be over-inclusive, as it classifies some acts or practices as discriminatory when they are not, whereas Hellman’s account turns out to lack explanatory power precisely insofar as it does not countenance a counterfactual condition on discrimination. By defending the necessity of our counterfactual condition, we set the conceptual limits for justified claims about the occurrence of discriminatory acts or practices in society, with immediate applications to the ethics of algorithmic decision-making.

This article argues against the idea that European Union (EU) member states (MSs) that have turned autocratic should be ejected from the EU to ensure that the latter does not itself violate the principle of democracy identified with the all subjected principle (ASP). First, the ASP requires that MSs be democratic before a decision to eject them would be acceptable and at that point, there is no reason to eject them. Second, if EU membership is voluntary as the protagonist of (...) the above idea presupposes, any MS can decide to leave at any point in time and other MSs can decide to leave any MS behind and create a new European organization without it. Taken together, this means that the ASP, which pertains to permanent subjection (to EU law), is irrelevant already from the outset and cannot be used as the main premise for the argument for ejection. Finally, the very disagreement about what kind of organization the EU is and should become, implies that the democratic rights of citizens be given priority over the rights of states. This speaks against the legitimacy of ejecting MSs for democracy protection. (shrink)

In many Western countries, the host society expects immigrants to learn the official language and often reacts in severe ways if they do not. One of the normative questions that arise in this context is whether immigrants have a moral duty to learn the host society’s language. The paper evaluates the four most promising arguments for why immigrants might have such a duty: respect towards the host society; the unavoidability of communication situations involving duties; the duty to avoid becoming reliant (...) on assistance from the welfare system; and a contract between the host society and immigrants. The paper argues that only the third and the fourth arguments support a moral obligation, and that they do so subject to several conditions and only for particular groups of immigrants. (shrink)

The important question of the legality of the state obliging trial incompetent defendants to receive competency-restoring treatment against their wishes, is one that has received much attention by legal scholars. Surprisingly, however, little attention has been paid to the, in many ways more fundamental, moral question of whether the state ought to administer such treatments. The aim of this paper is to start filling this gap in the literature. I begin by offering some reasons for thinking it morally acceptable to, (...) at least sometimes, oblige trial-incompetent defendants to receive competency-restoring treatments. The paper then discusses whether three prominent arguments (and their variations) offered by legal scholars against using non-consensual treatment to restore trial competence provide grounds for thinking there to be a general moral prohibition against these treatments. I argue that they do not. (shrink)

Does political realism have anything to contribute to the debates about migration in normative political theory? Anything well-established ‘moralist’ theories do not already acknowledge, that is? Addressing Jaggar’s (_Aristotelian Soc Suppl_ Vol. XCIV, pp. 87–113, 2020) and Finlayson’s (_Aristotelian Soc Suppl_ Vol. XCIV, pp. 115–139, 2020) critical intercessions into contemporary discourse about migration I argue that a political realist approach to the theory of migration faces what I call the ‘surplus challenge’: realists supposedly have no normative surplus over (liberal) cosmopolitan (...) and nationalist moralist approaches. This nothing-more-to-add narrative is a common argument against the possibility and integrity of political realism (as seen in, _inter alia_, Leader-Maynard and Worsnip in _Ethics_ 128(4), pp. 756–787, 2018). I show how it misconstrues the realist agenda. Finlayson, on the other hand, paints the realist intervention as primarily about paying closer attention to colonialism’s long legacy. A properly radical intrusion, however, addresses the unchecked and unwarranted, overbearing normative power of moral principles. I will conclude that for the realist, shaking up the discipline will not come as easy as pointing at some overly historicised facts. However, and despite this, the realist intervention rightly problematises contemporary philosophy of migration for its moral normativism. A radical realist approach to issues of migration, which unmasks the unjustified ‘microphysics’ political power hiding behind normative veneers, is a properly cataclysmic intrusion and the right way forward.

This article provides a normative framework for evaluating the moral permissibility of various defences of European Union (EU) values against their violation in EU member states. This requires, first, a coherent interpretation of EU values as the values of liberal democracy; second, a clear notion of when they are violated; third, a theory of how liberal democracy can be defended with measures that are consistent with the values of liberal democracy themselves; and, finally, a discussion of what the EU’s role (...) is in this defence. The article argues that it would be permissible for the EU to combine a number of political, cultural, socio-economic and legal responses in a concentric defence of liberal democracy as long as they respect the separation of powers doctrine and do not rely on problematic notions of collective responsibility.

Conscience is an idea that has significant currency in liberal democratic societies. Yet contemporary moral philosophical scholarship on conscience is surprisingly sparse. This paper seeks to offer a rigorous philosophical account of the role of conscience in moral life with a view to informing debates about the ethics of conscientious objection in medicine. I argue that conscience is concerned with a commitment to moral integrity and that restrictions on freedom of conscience prevent agents from living a moral life. In section (...) one I argue that conscience is a principle of moral awareness in rational agents, and that it yields an awareness of the personal nature of moral obligation. Conscience also monitors the coherence between an agent’s identity-conferring beliefs and intentions and their practical actions. In section two I consider how human beings are harmed when they are forced to violate their conscience. Restrictions on the exercise of conscience prevent people from living in accord with their own considered understanding of the requirements of morality and undermine one’s capacity for moral agency. This article concludes with a consideration of how a robust theory of conscience can inform our understanding of conscientious objection in medicine. I argue that it is in the interest of individual practitioners and the medical profession generally to foster moral agency among doctors. This provides a prima facie justification for permitting at least some kinds of conscientious objection. (shrink)

Recently, there has been an effort to make libertarianism compatible with a redistributive inheritance tax: When the tax is levied, the taxpayer in question is already dead and as such she cannot be a bearer of rights. The state is therefore allowed to redistribute the (value of) the estate according to some distributive principle. I consider (and finally dismiss) four successive arguments, each concluding that the state is allowed to use the estate for redistributive purposes. I show that neither of (...) them is able to reconcile (right-) libertarianism with a redistributive inheritance tax. Instead of trying to square the circle, proponents of such a tax should meet the theoretical essentials of (right-) libertarianism head-on. (shrink)

Algorithmic discrimination has rapidly become a topic of intense public and academic interest. This article explores three issues raised by algorithmic discrimination: 1) the distinction between direct and indirect discrimination, 2) the notion of disadvantageous treatment, and 3) the moral badness of discriminatory automated decision-making. It argues that some conventional distinctions between direct and indirect discrimination appear not to apply to algorithmic discrimination, that algorithmic discrimination may often be discrimination between groups, as opposed to against groups, and that it is (...) not necessarily the case that morally bad algorithmic discrimination gives us reason to not use automated decision-making. For each of the three issues, the article explores implications for algorithmic discrimination, suggests some alternative answers, and clarifies how we may want to think of discrimination more broadly in light of lessons drawn from the context of algorithmic discrimination.

Several philosophers argue for the ‘convergence thesis’ for positional goods: prioritarians, sufficientarians, and egalitarians may converge on favouring an equal (or not too unequal) distribution of goods that have positional aspects. I discuss some problems for this thesis when applied to two key goods for which it has been proposed: education and wealth. I show, however, that there is a variant of the thesis that avoids these problems. This version of the thesis is significant, I demonstrate, because it applies to (...) a person’s status as a citizen, which I suggest is the central concern of social or ‘relational’ egalitarianism.
