    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 (...)

    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 (...)

  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 (...)

    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 (...)

    The Typicality Effect in Basic Needs.Thomas Pölzler & Ivar R. Hannikainen - 2022 - Synthese 200 (5):1-26.
    According to the so-called Classical Theory, concepts are mentally represented by individually necessary and jointly sufficient application conditions. One of the principal empirical objections against this view stems from evidence that people judge some instances of a concept to be more typical than others. In this paper we present and discuss four empirical studies that investigate the extent to which this ‘typicality effect’ holds for the concept of basic needs. Through multiple operationalizations of typicality, our studies yielded evidence for a (...)

    Governance Quality Indicators for Organ Procurement Policies.David Rodríguez-Arias, Alberto Molina-Pérez, Ivar R. Hannikainen, Janet Delgado, Benjamin Söchtig, Sabine Wöhlke & Silke Schicktanz - 2021 - PLoS ONE 16 (6):e0252686.
    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 (...)
