    The Philosophy of Online Manipulation (edited book)
    Routledge. 2022.
    Are we being manipulated online? If so, is being manipulated by online technologies and algorithmic systems notably different from human forms of manipulation? And what is under threat exactly when people are manipulated online? This volume provides philosophical and conceptual depth to debates in digital ethics about online manipulation. The contributions explore the ramifications of our increasingly consequential interactions with online technologies such as online recommender systems, social …Read more

    Evolutionary Ethics
    Introduction to Philosophy: Ethics. 2019.
    This chapter first introduces naturalistic approaches to ethics more generally and distinguishes methodological ethical naturalism (the focus of this chapter), from metaphysical ethical naturalism. The second part then discusses evolutionary ethics as a specific variant of methodological ethical naturalism. After introducing the concepts of evolutionary theory that are relevant for evolutionary ethics, I will sketch the history of evolutionary ethics, which offers an interesting lesson about why…Read more

    Artificial Intelligence (AI) is increasingly adopted in society, creating numerous opportunities but at the same time posing ethical challenges. Many of these are familiar, such as issues of fairness, responsibility and privacy, but are presented in a new and challenging guise due to our limited ability to steer and predict the outputs of AI systems. This chapter first introduces these ethical challenges, stressing that overviews of values are a good starting point but frequently fail to suffice…Read more

    Social media use is soaring globally. Existing research of its ethical implications predominantly focuses on the relationships amongst human users online, and their effects. The nature of the software-to-human relationship and its impact on digital well-being, however, has not been sufficiently addressed yet. This paper aims to close the gap. I argue that some intelligent software agents, such as newsfeed curator algorithms in social media, manipulate human users because they do not intend their…Read more

    Can Moral Realists Deflect Defeat Due to Evolutionary Explanations of Morality?
    Pacific Philosophical Quarterly 98 (S1): 227-248. 2017.
    I address Andrew Moon's recent discussion (2016, this journal) of the question whether third-factor accounts are valid responses to debunking arguments against moral realism. Moon argues that third-factor responses are valid under certain conditions but leaves open whether moral realists can use his interpretation of the third-factor response to defuse the evolutionary debunking challenge. I rebut Moon's claim and answer his question. Moon's third-factor reply is valid only if we accept external…Read more

    Autonomy and Online Manipulation
    with Jeff Hancock
    Internet Policy Review 1 1-11. 2019.
    More and more researchers argue that online technologies manipulate human users and, therefore, undermine their autonomy. We call this the MAL view on online technology because it argues from Manipulation to Autonomy-Loss. MAL enjoys public visibility and will shape the academic discussion to come. This view of online technology, however, fails conceptually. MAL presupposes that manipulation equals autonomy loss, and that autonomy is the absence of manipulation. That is mistaken. In short, an in…Read more

    This article argues that manipulation is negligent influence. Manipulation is negligent in the sense that manipulators do not chose their method of influence because for its potential to reveal reasons to their victims. Thus, manipulation is a lack of care, or negligence, exclusively understood exclusively in terms of how one influences. That makes the proposed account superior to the most influential alternative, which analyses manipulation disjunctively as violation of several distinct types o…Read more

    Moral Philosophy and the ‘Ethical Turn’ in Anthropology
    Zeitschrift Für Ethik Und Moralphilosophie (2): 1-23. 2019.
    Moral philosophy continues to be enriched by an ongoing empirical turn,mainly through contributions from neuroscience, biology, and psychology. Thusfar, cultural anthropology has largely been missing. A recent and rapidly growing‘ethical turn’ within cultural anthropologynow explicitly and systematically studiesmorality. This research report aims to introduce to an audience in moral philosophyseveral notable works within the ethical turn. It does so by critically discussing theethical turn’s con…Read more

    (Online) Manipulation: Sometimes Hidden, Always Careless
    Review of Social Economy. forthcoming.
    Ever-increasing numbers of human interactions with intelligent software agents, online and offline, and their increasing ability to influence humans have prompted a surge in attention toward the concept of (online) manipulation. Several scholars have argued that manipulative influence is always hidden. But manipulation is sometimes overt, and when this is acknowledged the distinction between manipulation and other forms of social influence becomes problematic. Therefore, we need a better concept…Read more

    Debunking, Epistemic Achievement, and Undermining Defeat
    American Philosophical Quarterly 59 (1): 43-60. 2022.
    Several anti-debunkers have argued that evolutionary explanations of our moral beliefs fail to meet a necessary condition on undermining defeat called modal security. They conclude that evolution, therefore, does not debunk our moral beliefs. This article shows that modal security is false if knowledge is virtuous achievement. New information can undermine a given belief without providing reason to doubt that that belief is sensitive or safe. This leads to a novel conception of undermining defea…Read more

    The Influence of Situational Factors in Sacrificial Dilemmas on Utilitarian Moral Judgments
    Review of Philosophy and Psychology 13 (3): 593-625. 2022.
    The standard way to test alternative descriptive theories of moral judgment is by asking subjects to evaluate (amongst others) sacrificial dilemmas, where acting classifies as a utilitarian moral judgment and not acting classifies as a deontological moral judgment. Previous research uncovered many situational factors that alter subject’s moral judgments without affecting which type of action utilitarianism or deontology would recommend. This literature review provides a systematic analysis of th…Read more

    Most epistemologists maintain that we are rationally required to believe what our evidence supports. Generally speaking, any factor that makes it more probable that a given state of affairs obtains (or does not obtain) is evidence (for that state of affairs). In line with this view, many metaethicists believe that we are rationally required to believe what’s morally right and wrong based on what our moral evidence (e.g. our moral intuitions, along with descriptive information about the world) su…Read more

    Moral Luck and Unfair Blame
    Journal of Value Inquiry 1-17. 2021.
    Moral luck occurs when factors beyond an agent’s control affect her blameworthiness. Several scholars deny the existence of moral luck by distinguishing judging blameworthy from blame-related practices. Luck does not affect an agent’s blameworthiness because morality is conceptually fair, but it can affect the appropriate degree of blame for that agent. While separatism resolves the paradox of moral luck, we aim to show it that it needs amendment, because it is unfair to treat two equally blamew…Read more

    Ethics of digital contact tracing and COVID-19: who is (not) free to go?
    with Hein Duijf
    Ethics and Information Technology 23 (1): 69-77. 2020.
    Digital tracing technologies are heralded as an effective way of containing SARS-CoV-2 faster than it is spreading, thereby allowing the possibility of easing draconic measures of population-wide quarantine. But existing technological proposals risk addressing the wrong problem. The proper objective is not solely to maximise the ratio of people freed from quarantine but to also ensure that the composition of the freed group is fair. We identify several factors that pose a risk for fair group com…Read more

    Why Metaethics Needs Empirical Moral Psychology
    Critica 52 (155): 27-54. 2020.
    What is the significance of empirical moral psychology for metaethics? In this article we take up Michael Ruse’s evolutionary debunking argument against moral realism and reassess it in the context of the empirical state of the art. Ruse’s argument depends on the phenomenological presumption that people generally experience morality as objective. We demonstrate how recent experimental findings challenge this widely-shared armchair presumption and conclude that Ruse’s argument fails. We situate t…Read more

    Moral Judgement and Moral Progress: The Problem of Cognitive Control
    Philosophical Psychology 34 (7): 938-961. 2021.
    We propose a fundamental challenge to the feasibility of moral progress: most extant theories of progress, we will argue, assume an unrealistic level of cognitive control people must have over their moral judgments for moral progress to occur. Moral progress depends at least in part on the possibility of individual people improving their moral cognition to eliminate the pernicious influence of various epistemically defective biases and other distorting factors. Since the degree of control people…Read more

    Evolutionary debunking arguments purport to show that robust moral realism, the metaethical view that there are non-natural and mind-independent moral properties and facts that we can know about, is incompatible with evolutionary explanations of morality. One of the most prominent evolutionary debunking arguments is advanced by Sharon Street, who argues that if moral realism were true, then objective moral knowledge is unlikely because realist moral properties are evolutionary irrelevant and mor…Read more

    Manipulation, injustice, and technology
    In Michael Klenk & Fleur Jongepier (eds.), The Philosophy of Online Manipulation, Routledge. pp. 108-131. 2022.
    This chapter defends the view that manipulated behaviour is explained by an injustice. Injustices that explain manipulated behaviour need not involve agential features such as intentionality. Therefore, technology can manipulate us, even if technological artefacts like robots, intelligent software agents, or other ‘mere tools’ lack agential features such as intentionality. The chapter thus sketches a comprehensive account of manipulated behaviour related to but distinct from existing accounts of…Read more

    Measuring Moral Development
    de Filosoof 75 21-23. 2017.
    In the aftermath of the financial crisis, heightened awareness of ethical issues has sparked increased efforts toward moral education within universities and businesses. In many cases, psychological tests are used to measure whether moral development occurs. As long as we understand moral development as synonymous with moral progress, this may seem like a good sign: it would appear that such tests give us a handle on moral progress. Alas, moral development and moral progress are two very differe…Read more

    Prometheus' Legacy: Responsibility and Technology
    In Birgit Recki (ed.), Welche Technik?, Text & Dialog. pp. 23-40. 2020.
    A prominent view in contemporary philosophy of technology suggests that more technology implies more possibilities and, therefore, more responsibilities. Consequently, the question ‘What technology?’ is discussed primarily on the backdrop of assessing, assigning, and avoiding technology-borne culpability. The view is reminiscent of the Olympian gods’ vengeful and harsh reaction to Prometheus’ play with fire. However, the Olympian view leaves unexplained how technologies increase possibilities. A…Read more

    Omnivores and Synthesisers: Academic Philosophers as Interdisciplinary Specialists
    In Wouter Floria Kalf, Michael Klenk, Jeroen Hopster & Julia Hermann (eds.), Philosophy in the Age of Science?: Inquiries Into Philosophical Progress, Method, and Societal Relevance, Rowman & Littlefield Publishers. pp. 173-194. 2020.
    I stipulate that an academic discipline is societally relevant insofar as it helps to resolve a society’s real problems. What makes such a view correct depends on meta-normative views. I show how one’s meta-normative view significantly determines the likelihood that disciplinary philosophy is of societal relevance. On normative non-naturalism, normative naturalism, and normative scepticism, the societal relevance of philosophy is in doubt. I then argue that philosophers should aim for two remedi…Read more

    Third factor explanations and disagreement in metaethics
    Synthese 197 (1): 427-446. 2020.
    Several moral objectivists try to explain the reliability of moral beliefs by appealing to a third factor, a substantive moral claim that explains, first, why we have the moral beliefs that we have and, second, why these beliefs are true. Folke Tersman has recently suggested that moral disagreement constrains the epistemic legitimacy of third-factor explanations. Apart from constraining third-factor explanations, Tersman’s challenge could support the view that the epistemic significance of debun…Read more

    Higher Order Evidence and Moral Epistemology (edited book)
    Routledge. 2020.
    This book offers a systematic look at current challenges in moral epistemology through the lens of research on higher-order evidence. Fueled by recent advances in empirical research, higher-order evidence has generated a wealth of insights about the genealogy of moral beliefs. Higher-Order Evidence and Moral Epistemology explores how these insights have an impact on the epistemic status of moral beliefs. The essays are divided into four thematic sections. Part I addresses the normative signific…Read more

    I make a case for distinguishing clearly between subjective and objective accounts of undercutting defeat and for rejecting a hybrid view that takes both subjective and objective elements to be relevant for whether or not a belief is defeated. Moderate subjectivists claim that taking a belief to be defeated is sufficient for the belief to be defeated; subjectivist idealists add that if an idealised agent takes a belief to be defeated then the belief is defeated. Subjectivist idealism evades some…Read more

    Recent Work on Moral Revolutions
    with Elizabeth O’Neill, Chirag Arora, Charlie Blunden, Cecilie Eriksen, Lily Frank, and Jeroen Hopster
    Analysis 82 (2): 354-366. 2022.
    In the last few decades, several philosophers have written on the topic of moral revolutions, distinguishing them from other kinds of society-level moral change. This article surveys recent accounts of moral revolutions in moral philosophy. Different authors use quite different criteria to pick out moral revolutions. Features treated as relevant include radicality, depth or fundamentality, pervasiveness, novelty and particular causes. We also characterize the factors that have been proposed to c…Read more

    How Do Technological Artefacts Embody Moral Values?
    Philosophy and Technology 34 (3): 525-544. 2020.
    According to some philosophers of technology, technology embodies moral values in virtue of its functional properties and the intentions of its designers. But this paper shows that such an account makes the values supposedly embedded in technology epistemically opaque and that it does not allow for values to change. Therefore, to overcome these shortcomings, the paper introduces the novel Affordance Account of Value Embedding as a superior alternative. Accordingly, artefacts bear affordances, th…Read more

    Thomas Pölzler, Moral Reality and the Empirical Sciences (review)
    International Journal for the Study of Skepticism 11 (1): 78-86. 2019.
    Thomas Pölzler’s book offers the first detailed study that focuses explicitly on the promise of science-based arguments for and against moral realism (of both the natural and non-natural kind). His two central claims are that sound arguments bearing on the realism/anti-realism debate are possible, and, yet, that four central attempts to derive metaethical conclusions from science-based arguments uniformly fail. The book then provides several recommendations for future science-based contributions…Read more
