    Trolleys, Triage and Covid-19: The Role of Psychological Realism in Sacrificial Dilemmas.Markus Kneer & Ivar R. Hannikainen - 2022 - Cognition and Emotion 36 (1):137-153.
    At the height of the Covid-19 pandemic, frontline medical professionals at intensive care units around the world faced gruesome decisions about how to ration life-saving medical resources. These events provided a unique lens through which to understand how the public reasons about real-world dilemmas involving trade-offs between human lives. In three studies (total N = 2298), we examined people’s moral attitudes toward the triage of acute coronavirus patients, and found elevated support for utilitarian triage policies. These utilitarian tendencies did not (...)

    Experimental Philosophical Bioethics and Normative Inference.Brian D. Earp, Jonathan Lewis, Vilius Dranseika & Ivar R. Hannikainen - 2021 - Theoretical Medicine and Bioethics 42 (3-4):91-111.
    This paper explores an emerging sub-field of both empirical bioethics and experimental philosophy, which has been called “experimental philosophical bioethics” (bioxphi). As an empirical discipline, bioxphi adopts the methods of experimental moral psychology and cognitive science; it does so to make sense of the eliciting factors and underlying cognitive processes that shape people’s moral judgments, particularly about real-world matters of bioethical concern. Yet, as a normative discipline situated within the broader field of bioethics, it also aims to contribute to substantive (...)

  3. Fuller and the Folk: The Inner Morality of Law Revisited.Raff Donelson & Ivar R. Hannikainen - 2020 - In Oxford Studies in Experimental Philosophy, Volume 3. Oxford: pp. 6-28.
    The experimental turn in philosophy has reached several sub-fields including ethics, epistemology, and metaphysics. This paper is among the first to apply experimental techniques to questions in the philosophy of law. Specifically, we examine Lon Fuller's procedural natural law theory. Fuller famously claimed that legal systems necessarily observe eight principles he called "the inner morality of law." We evaluate Fuller's claim by surveying both ordinary people and legal experts about their intuitions about legal systems. We conclude that, at best, we (...)

Vosgerichian, Xueyi Zhang & Jing Zhu - 2019 - Frontiers in Psychology 10.
    Philosophers have long debated whether, if determinism is true, we should hold people morally responsible for their actions since in a deterministic universe, people are arguably not the ultimate source of their actions nor could they have done otherwise if initial conditions and the laws of nature are held fixed. To reveal how non-philosophers ordinarily reason about the conditions for free will, we conducted a cross-cultural and cross-linguistic survey (N = 5,268) spanning twenty countries and sixteen languages. Overall, participants tended (...)

    The Folk Concept of Law: Law Is Intrinsically Moral.Brian Flanagan & Ivar R. Hannikainen - 2022 - Australasian Journal of Philosophy 100 (1):165-179.
    ABSTRACT Most theorists agree that our social order includes a distinctive legal dimension. A fundamental question is that of whether reference to specific legal phenomena always involves a commitment to a particular moral view. Whereas many philosophers advance the ‘positivist’ claim that any correspondence between morality and the law is just a function of political circumstance, natural law theorists insist that law is intrinsically moral. Each school claims the crucial advantage of consistency with our folk concept. Drawing on the notion (...)

    Legal Decision-Making and the Abstract/Concrete Paradox.Noel Struchiner, Guilherme da F. C. F. De Almeida & Ivar R. Hannikainen - 2020 - Cognition 205:104421.
    Higher courts sometimes assess the constitutionality of law by working through a concrete case, other times by reasoning about the underlying question in a more abstract way. Prior research has found that the degree of concreteness or abstraction with which an issue is formulated can influence people's prescriptive views: For instance, people often endorse punishment for concrete misdeeds that they would oppose if the circumstances were described abstractly. We sought to understand whether the so-called ‘abstract/concrete paradox’ also jeopardizes the consistency (...)

    Are There Cross-Cultural Legal Principles? Modal Reasoning Uncovers Procedural Constraints on Law.Ivar R. Hannikainen, Kevin P. Tobia, Guilherme da F. C. F. De Almeida, Raff Donelson, Vilius Dranseika, Markus Kneer, Niek Strohmaier, Piotr Bystranowski, Kristina Dolinina, Bartosz Janik, Sothie Keo, Eglė Lauraitytė, Alice Liefgreen, Maciej Próchnicki, Alejandro Rosas & Noel Struchiner - 2021 - Cognitive Science 45 (8):e13024.
    Despite pervasive variation in the content of laws, legal theorists and anthropologists have argued that laws share certain abstract features and even speculated that law may be a human universal. In the present report, we evaluate this thesis through an experiment administered in 11 different countries. Are there cross-cultural principles of law? In a between-subjects design, participants (N = 3,054) were asked whether there could be laws that violate certain procedural principles (e.g., laws applied retrospectively or unintelligible laws), and also (...)

    How Pills Undermine Skills: Moralization of Cognitive Enhancement and Causal Selection.Emilian Mihailov, Blanca Rodríguez López, Florian Cova & Ivar R. Hannikainen - 2021 - Consciousness and Cognition 91:103120.
    Despite the promise to boost human potential and wellbeing, enhancement drugs face recurring ethical scrutiny. The present studies examined attitudes toward cognitive enhancement in order to learn more about these ethical concerns, who has them, and the circumstances in which they arise. Fairness-based concerns underlay opposition to competitive use—even though enhancement drugs were described as legal, accessible and affordable. Moral values also influenced how subsequent rewards were causally explained: Opposition to competitive use reduced the causal contribution of the enhanced winner’s (...)

    Act Versus Impact: Conservatives and Liberals Exhibit Different Structural Emphases in Moral Judgment.Ivar R. Hannikainen, Ryan M. Miller & Fiery A. Cushman - 2017 - Ratio 30 (4):462-493.
    Conservatives and liberals disagree sharply on matters of morality and public policy. We propose a novel account of the psychological basis of these differences. Specifically, we find that conservatives tend to emphasize the intrinsic value of actions during moral judgment, in part by mentally simulating themselves performing those actions, while liberals instead emphasize the value of the expected outcomes of the action. We then demonstrate that a structural emphasis on actions is linked to the condemnation of victimless crimes, a distinctive (...)

    Background Consent policies for post-mortem organ procurement (OP) vary throughout Europe, and yet no studies have empirically evaluated the ethical implications of contrasting consent models. To fill this gap, we introduce a novel indicator of governance quality based on the ideal of informed support, and examine national differences on this measure through a quantitative survey of OP policy informedness and preferences in seven European countries. -/- Methods Between 2017–2019, we conducted a convenience sample survey of students (n = 2006) in (...)

    Do Formalist Judges Abide By Their Abstract Principles? A Two-Country Study in Adjudication.Piotr Bystranowski, Bartosz Janik, Maciej Próchnicki, Ivar Rodriguez Hannikainen, Guilherme da Franca Couto Fernandes de Almeida & Noel Struchiner - forthcoming - International Journal for the Semiotics of Law - Revue Internationale de Sémiotique Juridique:1-33.
    Recent literature in experimental philosophy has postulated the existence of the abstract/concrete paradox : the tendency to activate inconsistent intuitions depending on whether a problem to be analyzed is framed in abstract terms or is described as a concrete case. One recent study supports the thesis that this effect influences judicial decision-making, including decision-making by professional judges, in areas such as interpretation of constitutional principles and application of clear-cut rules. Here, following the existing literature in legal theory, we argue that (...)

    Guilt Without Fault: Accidental Agency in the Era of Autonomous Vehicles.Fernando Aguiar, Ivar R. Hannikainen & Pilar Aguilar - 2022 - Science and Engineering Ethics 28 (2):1-22.
    The control principle implies that people should not feel guilt for outcomes beyond their control. Yet, the so-called ‘agent and observer puzzles’ in philosophy demonstrate that people waver in their commitment to the control principle when reflecting on accidental outcomes. In the context of car accidents involving conventional or autonomous vehicles, Study 1 established that judgments of responsibility are most strongly associated with expressions of guilt–over and above other negative emotions, such as sadness, remorse or anger. Studies 2 and 3 (...)
