  1. Ethics of digital contact tracing and COVID-19: who is (not) free to go?Michael Klenk & Hein Duijf - 2020 - Ethics and Information Technology 23 (1):69-77.
    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 composition along with an analysis (...)

    Should one trust experts?Hein Duijf - 2021 - Synthese 199 (3-4):9289-9312.
    Should one trust experts? My answer to this question is a qualified ‘no’. In this paper I explore the conditions under which it is rational to trust and defer to experts, and those under which it may be rational to refrain from doing so. I draw on two important factors for an actor’s trust in a partner: trust depends on the partner’s competence and on the partner’s interests. I propose that the conditions under which it is rational to trust and (...)

    Responsibility Voids and Cooperation.Hein Duijf - 2018 - Philosophy of the Social Sciences 48 (4):434-460.
    Do responsibility voids exist? That is, are there situations in which the group is collectively morally responsible for some outcome although no member can be held individually morally responsible for it? To answer these questions, I draw a distinction between competitive and cooperative decision contexts based on the team-reasoning account of cooperation. Accordingly, I provide a reasoning-based analysis of cooperation, competition, moral responsibility, and, last, potential responsibility voids. I then argue that competitive decision contexts are free of responsibility voids. The (...)

  4. Collective obligations, group plans and individual actions.Allard Tamminga & Hein Duijf - 2017 - Economics and Philosophy 33 (2):187-214.
    If group members aim to fulfill a collective obligation, they must act in such a way that the composition of their individual actions amounts to a group action that fulfills the collective obligation. We study a strong sense of joint action in which the members of a group design and then publicly adopt a group plan that coordinates the individual actions of the group members. We characterize the conditions under which a group plan successfully coordinates the group members' individual actions, (...)

  5. Cooperation, fairness and team reasoning.Hein Duijf - 2021 - Economics and Philosophy 37 (3):413-440.
    This paper examines two strands of literature regarding economic models of cooperation. First, payoff transformation theories assume that people may not be exclusively motivated by self-interest, but also care about equality and fairness. Second, team reasoning theorists assume that people might reason from the perspective of the team, rather than an individualistic perspective. Can these two theories be unified? In contrast to the consensus among team reasoning theorists, I argue that team reasoning can be viewed as a particular type of (...)

    Expressivity results for deontic logics of collective agency.Allard Tamminga, Hein Duijf & Frederik Van De Putte - 2021 - Synthese 198 (9):8733-8753.
    We use a deontic logic of collective agency to study reducibility questions about collective agency and collective obligations. The logic that is at the basis of our study is a multi-modal logic in the tradition of *stit* logics of agency. Our full formal language has constants for collective and individual deontic admissibility, modalities for collective and individual agency, and modalities for collective and individual obligations. We classify its twenty-seven sublanguages in terms of their expressive power. This classification enables us to (...)

    When should one be open-minded?Hein Duijf - 2024 - Philosophical Studies 181 (5):1257-1296.
    It is widely believed among philosophers and educated people that it is virtuous to be open-minded. Instead of thinking of open-mindedness as universally or unconditionally epistemically valuable, I argue that it is vital to explicate the conditions that must obtain if open-mindedness is to be epistemically valuable. This paper critically evaluates open-mindedness given certain realistic cognitive limitations. I present and analyse a simple mathematical model of open-minded decision-making that incorporates these limitations. The results are mixed. The bad news is that (...)

    Conflicting intentions: rectifying the consistency requirements.Hein Duijf, Jan Broersen & John-Jules Ch Meyer - 2019 - Philosophical Studies 176 (4):1097-1118.
    Many philosophers are convinced that rationality dictates that one’s overall set of intentions be consistent. The starting point and inspiration for our study is Bratman’s planning theory of intentions. According to this theory, one needs to appeal to the fulfilment of characteristic planning roles to justify norms that apply to our intentions. Our main objective is to demonstrate that one can be rational despite having mutually inconsistent intentions. Conversely, it is also shown that one can be irrational despite having a (...)

    A Logical Study of Moral Responsibility.Hein Duijf - forthcoming - Erkenntnis:1-42.
    This paper proposes a logical framework for studying the structure of moral responsibility for outcomes. The analysis incorporates two vital features: an agency condition and a negative condition of an alternative possibility. The logical language allows us to identify and disambiguate seven plausible criteria for moral responsibility. To accommodate interdependent decision contexts, the semantics are given in terms of so-called responsibility games. The logical framework enables us to classify the logical relations between these seven criteria for moral responsibility. Although all (...)

  10. An impossibility result on methodological individualism.Hein Duijf, Allard Tamminga & Frederik Van De Putte - 2021 - Philosophical Studies 178 (12):4165-4185.
    Methodological individualists often claim that any social phenomenon can ultimately be explained in terms of the actions and interactions of individuals. Any Nagelian version of methodological individualism requires that there be bridge laws that translate social statements into individualistic ones. We show that Nagelian individualism can be put to logical scrutiny by making the relevant social and individualistic languages fully explicit and mathematically precise. In particular, we prove that the social statement that a group of (at least two) agents performs (...)

    Doing Without Action Types.Hein Duijf, Jan Broersen, Alexandra Kuncová & Aldo Iván Ramírez Abarca - 2021 - Review of Symbolic Logic 14 (2):380-410.
    This paper explores the analysis of ability, where ability is to be understood in the epistemic sense—in contrast to what might be called a causal sense. There are plenty of cases where an agent is able to perform an action that guarantees a given result even though she does not know which of her actions guarantees that result. Such an agent possesses the causal ability but lacks the epistemic ability. The standard analysis of such epistemic abilities relies on the notion (...)

    Uniting social constructivism and logic.Hein Duijf - forthcoming - Metascience:1-4.
    Mahoney undertakes the wide-reaching project of providing foundations for the social sciences by building on the set-theoretic framework. I enjoyed reading the book and laud the accessible writing style and the wealth of examples from case studies, making it an engaging read despite its methodological aim. The main aims of the book are threefold: (1) to introduce the theory of scientific constructivism, (2) to introduce the set-theoretic methodology that captures the logic of scientific-constructivist research, and (3) to provide and develop (...)

    The Logic of Responsibility Voids.Hein Duijf - 2022 - Springer Cham.
    This book focuses on the problem of responsibility voids: these are cases where responsibility for a morally undesirable outcome cannot be attributed to any of the involved agents. Responsibility voids are thought to occur in collective decision-making and in the context of artificial intelligent systems. In these cases, philosophers worry that there is a shortfall of moral responsibility. In particular, such voids are often assumed to justify a notion of collective responsibility that cannot be reduced to individual responsibility. One of (...)
