Borderline personality traits and empathy as predictors of moral decision-making in trolley problems and variants

BackgroundThe present study demonstrated a causal effect of participants’ perspectives on moral decision-making by using Trolley problems and variants. Furthermore, we investigated whether empathy and borderline personality traits (BDL traits) significantly predicted participants’ choices. We used a classical Trolley problem (a causing harm scenario) and an everyday trolley-like problem (a causing inconvenience scenario). MethodsSubjects voluntarily participated in our study (N = 427, women: 54%), fulfilled BDL traits and empathy questionnaires, and randomly completed the two types of Trolley problems, presenting both three perspectives. ResultsWe provided strong evidence that participants’ perspectives on trolley problems and variants caused significant changes in their moral decision-making. Additionally, affective empathy and BDL traits significantly predicted participants’ decisions of the causing inconvenience scenario, while only BDL traits predicted choices in the causing harm scenario. ConclusionsThis study addressed several originalities by providing new experimental materials, causal results, and the significant influence of BDL traits and affective empathy on moral decision-making. These findings raised fundamental questions that are developed in the discussion.

The Ethics of Automated Vehicles: Why Self-driving Cars Should not Swerve in Dilemma Cases

In this paper, I will argue that automated vehicles should not swerve to avoid a person or vehicle in its path, unless they can do so without imposing risks onto others. I will argue that this is the conclusion that we should reach even if we start by assuming that we should divert the trolley in the standard trolley case (in which the trolley will hit and kill five people on the track, unless it is diverted onto a different track, where it will hit and kill just one person). In defence of this claim, I appeal to the distribution of moral and legal responsibilities, highlighting the importance of safe spaces, and arguing in favour of constraints on what can be done to minimise casualties. My arguments draw on the methodology associated with the trolley problem. As such, this paper also defends this methodology, highlighting a number of ways in which authors misunderstand and misrepresent the trolley problem. For example, the ‘trolley problem’ is not the ‘name given by philosophers to classic examples of unavoidable crash scenarios, historically involving runaway trolleys’, as Millar suggests, and trolley cases should not be compared with ‘model building in the (social) sciences’, as Gogoll and Müller suggest. Trolley cases have more in common with lab experiments than model building, and the problem referred to in the trolley problem is not the problem of deciding what to do in any one case. Rather, it refers to the problem of explaining what appear to be conflicting intuitions when we consider two cases together. The problem, for example, could be: how do we justify the claim that automated vehicles should not swerve even if we accept the claim that we should divert the trolley in an apparently similar trolley case?

Autonomous Driving Ethics: from Trolley Problem to Ethics of Risk

In 2017, the German ethics commission for automated and connected driving released 20 ethical guidelines for autonomous vehicles. It is now up to the research and industrial sectors to enhance the development of autonomous vehicles based on such guidelines. In the current state of the art, we find studies on how ethical theories can be integrated. To the best of the authors’ knowledge, no framework for motion planning has yet been published which allows for the true implementation of any practical ethical policies. This paper makes four contributions: Firstly, we briefly present the state of the art based on recent works concerning unavoidable accidents of autonomous vehicles (AVs) and identify further need for research. While most of the research focuses on decision strategies in moral dilemmas or crash optimization, we aim to develop an ethical trajectory planning for all situations on public roads. Secondly, we discuss several ethical theories and argue for the adoption of the theory “ethics of risk.” Thirdly, we propose a new framework for trajectory planning, with uncertainties and an assessment of risks. In this framework, we transform ethical specifications into mathematical equations and thus create the basis for the programming of an ethical trajectory. We present a risk cost function for trajectory planning that considers minimization of the overall risk, priority for the worst-off and equal treatment of people. Finally, we build a connection between the widely discussed trolley problem and our proposed framework.

Small-scale utilitarianism: High acceptance of utilitarian solutions to Trolley Problems among a horticultural population in Nicaragua

Researchers often use moral dilemmas to investigate the specific factors that influence participants’ judgments of the appropriateness of different actions. A common construction of such a dilemma is the Trolley Problem, which pits an obvious utilitarian solution against a common deontological dictum to not do harm to others. Cross-cultural studies have validated the robustness of numerous contextual biases, such as judging utilitarian decisions more negatively if they require contact with other individuals (contact bias), they force others to serve as a means to an end (means bias), and if they require direct action rather than inaction (omission bias). However, such cross-cultural research is largely limited to studies of industrialized, nation-state populations. Previous research has suggested that the more intimate community relationships that characterize small-scale populations might lead to important differences, such as an absence of an omission bias. Here we contribute to this literature by investigating perceptions of Trolley Problem solutions among a Mayangna/Miskito community, a small-scale indigenous population in Nicaragua. Compared to previously sampled populations, the Mayangna/Miskito participants report higher levels of acceptance of utilitarian solutions and do not exhibit an omission bias. We also examine the justifications participants offered to explore how Mayangna/Miskito culture might influence moral judgments.

Taking Exception: Philosophy of Technology as a Multidimensional Problem Space

This essay develops three key claims made in my 2018 book, Exceptional Technologies. Part one argues for ‘trivialising the transcendental’, to remove stigmas attached to the word ‘transcendental’ in philosophy in general and philosophy of technology in particular. Part two outlines the concept of ‘exceptional technologies’. These are artefacts and practices that show up as limit cases for our received pictures of what constitutes a ‘technology’ (what I refer to as our ‘pictures of method’) and that force us to reassess the conditions for the possibility of these pictures. I focus on the case of autonomous vehicles here, arguing that Google Street View provides a relatively better picture for approaching philosophical issues at stake than the famous ‘Trolley Problem’. Part three then concludes with a focus on Heidegger’s ‘Question Concerning Technology’ essay. Heidegger asserts that philosophical questioning ‘builds a way’ (1977: 3). I argue that philosophical approaches to technologies might better be considered in terms of a multidimensional problem space.

Trolley dilemma in the sky: Context matters when civilians and cadets make remotely piloted aircraft decisions

Crews operating remotely piloted aircrafts (RPAs) in military operations may be among the few that truly experience tragic dilemmas similar to the famous Trolley Problem. In order to analyze decision-making and emotional conflict of RPA operators within Trolley-Problem-like dilemma situations, we created an RPA simulation that varied mission contexts (firefighter, military and surveillance as a control condition) and the social “value” of a potential victim. We found that participants (Air Force cadets and civilian students) were less likely to make the common utilitarian choice (sacrificing one to save five), when the value of the one increased, especially in the military context. However, in the firefighter context, this decision pattern was much less pronounced. The results demonstrate behavioral and justification differences when people are more invested in a particular context despite ostensibly similar dilemmas.
