Strategies for improving the explainability of artificial agents are a key approach to support the understandability of artificial agents’ decision-making processes and their trustworthiness. However, since explanations are not inclined to standardization, finding solutions that fit the algorithmic-based decision-making processes of artificial agents poses a compelling challenge. This paper addresses the concept of trust in relation to complementary aspects that play a role in interpersonal and human–agent relationships, such as users’ confidence and their perception of artificial agents’ reliability. Particularly, this (...) paper focuses on non-expert users’ perspectives, since users with little technical knowledge are likely to benefit the most from “post-hoc”, everyday explanations. Drawing upon the explainable AI and social sciences literature, this paper investigates how artificial agent’s explainability and trust are interrelated at different stages of an interaction. Specifically, the possibility of implementing explainability as a trust building, trust maintenance and restoration strategy is investigated. To this extent, the paper identifies and discusses the intrinsic limits and fundamental features of explanations, such as structural qualities and communication strategies. Accordingly, this paper contributes to the debate by providing recommendations on how to maximize the effectiveness of explanations for supporting non-expert users’ understanding and trust. (shrink)

This study aimed to identify real-life experts working for a port authority and lay people (students) who played The Sustainable Port, a serious game aiming to simulate the dynamics occurring in a port area. To achieve this goal, we analyzed eye gaze data collected noninvasively using low-grade webcams from 28 participants working for the port authority of the Port of Rotterdam and 66 students. Such data were used for a classification task implemented using a MiniRocket classifier, an algorithm used for (...) time-series classification. The classifier reached an F1 score of 0.75 (SD = 0.07), a PR AUC of 0.73 (SD = 0.14), and an ROC AUC of 0.75 (SD = 0.15) providing evidence that it is possible to identify real-life experts about maritime port management using data that can be obtained from a webcam. We speculate that the gaze direction used to train the MiniRocket may contain relevant information about the cognitive processes and decisions occurring throughout the gameplay. We suggest that the methods here presented not only can be used to detect experts playing simulations, such as serious games, but also to identify experts tackling screen-presented tasks. (shrink)

Can an event’s blameworthiness distort whether people see it as intentional? In controversial recent studies, people judged a behavior’s negative side effect intentional even though the agent allegedly had no desire for it to occur. Such a judgment contradicts the standard assumption that desire is a necessary condition of intentionality, and it raises concerns about assessments of intentionality in legal settings. Six studies examined whether blameworthy events distort intentionality judgments. Studies 1 through 4 show that, counter to recent claims, intentionality (...) judgments are systematically guided by variations in the agent’s desire, for moral and nonmoral actions alike. Studies 5 and 6 show that a behavior’s negative side effects are rarely seen as intentional once people are allowed to choose from multiple descriptions of the behavior. Specifically, people distinguish between “knowingly” and “intentionally” bringing about a side effect, even for immoral actions. These studies suggest that intentionality judgments are unaffected by a behavior’s blameworthiness. (shrink)

Brain Computer Interfaces (BCIs) enable one to control peripheral ICT and robotic devices by processing brain activity on-line. The potential usefulness of BCI systems, initially demonstrated in rehabilitation medicine, is now being explored in education, entertainment, intensive workflow monitoring, security, and training. Ethical issues arising in connection with these investigations are triaged taking into account technological imminence and pervasiveness of BCI technologies. By focussing on imminent technological developments, ethical reflection is informatively grounded into realistic protocols of brain-to-computer communication. In particular, (...) it is argued that human-machine adaptation and shared control distinctively shape autonomy and responsibility issues in current BCI interaction environments. Novel personhood issues are identified and analyzed too. These notably concern (i) the “sub-personal” use of human beings in BCI-enabled cooperative problem solving, and (ii) the pro-active protection of personal identity which BCI rehabilitation therapies may afford, in the light of so-called motor theories of thinking, for the benefit of patients affected by severe motor disabilities.

Although the analogy between macroscopic machines and biological molecular devices plays an important role in the conceptual framework of both neo-mechanistic accounts and nanotechnology, it has recently been claimed that certain complex molecular devices cannot be considered machines since they are subject to physicochemical forces that are different from those of macroscopic machines. However, the structural and physicochemical conditions that allow both macroscopic machines and microscopic devices to work and perform new functions, through a combination of elemental functional parts, have (...) not yet been examined. In order to fill this void, this paper has a threefold aim: first, to clarify the structural and organisational conditions of macroscopic machines and microscopic devices; second, to determine whether the machine-like analogy fits nanoscale devices; and third, to assess whether the machine-like analogy is appropriate for describing the behaviour of some biological macromolecules. Finally, the paper gives an account of ‘machine’ which, while acknowledging the physicochemical and organisational differences between man-made machines and biological microscopic devices, nevertheless identifies a common conceptual core that allows us to consider the latter ‘machines’.

Extant models of moral judgment assume that an action’s intentionality precedes assignments of blame. Knobe (2003b) challenged this fundamental order and proposed instead that the badness or blameworthiness of an action directs (and thus unduly biases) people’s intentionality judgments. His and other researchers’ studies suggested that blameworthy actions are considered intentional even when the agent lacks skill (e.g., killing somebody with a lucky shot) whereas equivalent neutral actions are not (e.g., luckily hitting a bull’s-eye). The present five studies offer an (...) alternative account of these provocative findings. We suggest that people see the morally significant action examined in previous studies (killing) as accomplished by a basic action (pressing the trigger) for which an unskilled agent still has sufficient skill. Studies 1 through 3 show that when this basic action is performed unskillfully or is absent, people are far less likely to view the killing as intentional, demonstrating that intentionality judgments, even about immoral actions, are guided by skill information. Studies 4 and 5 further show that a neutral action such as hitting the bull’s-eye is more difficult than killing and that difficult actions are less often judged intentional. When difficulty is held constant, people’s intentionality judgments are fully responsive to skill information regardless of moral valence. The present studies thus speak against the hypothesis of a moral evaluation bias in intentionality judgments and instead document people’s sensitivity to subtle features of human action. (shrink)

Serious games are an effective method of reproducing aspects of the complex interplay between environments and stakeholders in business situations. In the game we describe here, The Sustainable Port, players experience what it is like to make decisions in such a complex environment. Their aim in the game is to grow the Port of Rotterdam while keeping economic growth in balance with sustainability goals. In this study, we assessed whether experienced Port of Rotterdam employees (PoR employees) show different psychophysiological patterns, (...) and more specifically EAR-derived features, compared to students. We did this on the assumption that physiological patterns will tell us something about how people who are familiar with the environment of the Port of Rotterdam, more specifically Port of Rotterdam employees, make decisions compared to those lacking such familiarity.Our sample consisted of 28 PoR employees and 65 students, all of whom played The Sustainable Port game and had their faces recorded with a camera. The Eye Aspect Ratio was extracted from these recordings and then from those we extracted EAR-derived features. Our results show that Port of Rotterdam employees perform better than students and that the two groups are characterized by different physiological variations in their EAR-derived features. A logistic regression model used to identify PoR employees and students obtained an F1 score of 0.62, a PR AUC score of 0.64, and a ROC AUC score of 0.70. performing significantly above baseline suggesting the effectiveness of using EAR-derived features for this task. Our interpretation was further confirmed by a pseudo-R2 score used to evaluate the goodness of fit of a logistic regression model on the entire dataset. We found that Port of Rotterdam employees had a lower variation in blink rate per minute (blinks/m) and higher variation in the root mean square difference of successive difference in blinks (RMSSD), the consecutive difference between two continuous blinks. Moreover, this study shows that our methods were robust enough to negate the effects of confounders, such as biological sex and age that affect some other studies that analyze blinks. (shrink)

Abstract. The rapid developments of robotics technologies in the last twenty years of the XX century have greatly encouraged research on the use of robots for surgery, diagnosis, rehabilitation, prosthetics, and assistance to disabled and elderly people. This chapter provides an overview of robotic technologies and systems for health care, focussing on various ethical problems that these technologies give rise to. These problems notably concern the protection of human physical and mental integrity, autonomy, responsibility, ...

The logic of gift and gratuitousness in business activity raised by the encyclical Caritas in Veritate stresses a deeper critical evaluation of the category of relation. The logic of gift in business includes two aspects. The first is considering the logic of gift as a new conceptual lens in order to view business relationship beyond contractual logic. In this view, it is crucial to see the circulation of goods as instrumental for the development of relationships. The second aspect is to (...) qualify the relationships established through the gift, and to think about the motivation in gift-giving, which has an ethical content. We give because we have received, and through gift-giving we develop relationships that have a high ‘bonding value’. Analysing the logic of gift in business management may permit us to gain an understanding of the ambiguity of gift-giving in organizations. Looking at the relationships between organizations and employees, and organizations and customers, we can discover why the logic of gift is often misunderstood or abused in its application, and how it should be applied to be more consistent with the message of Caritas in Veritate.

This article examines ethical implications of the growing AI carbon footprint, focusing on the fair distribution of prospective responsibilities among groups of involved actors. First, major groups of involved actors are identified, including AI scientists, AI industry, and AI infrastructure providers, from datacenters to electrical energy suppliers. Second, responsibilities of AI scientists concerning climate warming mitigation actions are disentangled from responsibilities of other involved actors. Third, to implement these responsibilities nudging interventions are suggested, leveraging on AI competitive games which would (...) prize research combining better system accuracy with greater computational and energy efficiency. Finally, in addition to the AI carbon footprint, it is argued that another ethical issue with a genuinely global dimension is now emerging in the AI ethics agenda. This issue concerns the threats that AI-powered cyberweapons pose to the digital command, control, and communication infrastructure of nuclear weapons systems. (shrink)

The fulcrum of this work is knowledge: what it is and how it is generated within the context of a capitalist society. First, Marx’s analysis of the objective labour process is extended to the mental labour process. Then, objective and mental labour processes are defined in terms of objective and mental transformations, with consideration paid to which of the two types of transformation is determinant. This requires a discussion of dialectical logic and formal logic. Within dialectical logic, two types of (...) processes are introduced: open ended and pre-determined. It is argued that computers (both traditional and quantum) and Artificial Intelligence cannot generate new knowledge, because they (a) rely on formal logic, i.e. they cannot engage in open-ended dialectical processes, and (b) are impervious to social determination. Connectedly, Artificial Intelligence systems such as ChatGPT cannot be a substitute for human thought or writing, because of the inevitability of ‘model collapse’. Next, focus is shifted to a specific form of knowledge: the ‘Copenhagen interpretation’ of quantum mechanics. It is shown that this interpretation is steeped in irrationalism and that it is a variant of pro-capitalist ideology. Finally, the social-historical roots of this ideology are revealed. (shrink)

This work focuses exclusively on the modern economic aspects of imperialism. We define it as a persistent and long-term net appropriation of surplus value by the high-technology imperialist countries from the low-technology dominated countries. This process is placed within the secular tendential fall in profitability, not only in the imperialist countries but also in the dominated ones. We identify four channels through which surplus value flows to the imperialist countries: currency seigniorage; income flows from capital investments; unequal exchange through trade; (...) and changes in exchange rates. We pay particular attention to the theorisation and quantification of international UE and of exchange-rate movements. Concerning UE, we extend Marx’s transformation procedure to the international setting. We use two variables in the analysis of UE: the organic composition of capital and the rate of exploitation, and we measure which of these two variables is more important in contributing to UE transfers. We research a time span longer than in any previous study. We also introduce the distinction between narrow and broad unequal exchange according to whether two countries are assumed to trade only with each other or also with the rest of the world. As for the analysis of the exchange rates as a channel for appropriation of international surplus value, we reject conventional approaches because they are rooted in equilibrium theory. We find very strong empirical evidence that exchange rates tend towards the point at which the productivities are equalised. This is only a tendency because this equalisation is inherently incompatible with the nature of imperialism. Finally, given its topicality, we apply our analysis to the relation between the US and China and find that China is not an imperialist country according to our definition and data. (shrink)

Brenner's ‘The Economics of Global Turbulence’ is a review of the world economy in the second half of the 20th century and its momentous changes. It deals with a wide range of issues and developments and is supported by a wealth of statistical and historical material. At the same time, it debunks many of the myths upon which recent history has been written. Perhaps even more importantly, it seeks the causes of crises in the laws of motion of capital itself.

For a general formulation of the undecidability and incompleteness theorems one has to characterize precisely the notion of formal system. Such a characterization is provided by the proposal to identify the intuitive concept of effectively calculable function with that of partial recursive function. A proper understanding of this identification, which is known under the name of "Church's thesis", is crucial for a philosophical assessment of these metamathematical results. The undecidability and incompleteness theorems suggest one major but certainly not the only (...) reason for interest in Church's thesis. The thesis provides a sharp characterization of a concept that has played an epistemologically motivated role in many logical and foundational investigations and that has been appealed to in methodological discussions concerning computational approaches in cognitive psychology. ;In spite of these various motives of interest a detailed philosophical analysis of the meaning and the epistemological status of Church's thesis has been neglected; a thorough and balanced presentation of arguments for it is lacking. This seems to me to be due to two widespread views of the thesis, both tending to discourage analytical work. According to the first of these views, Church's thesis is unproblematic because the classical arguments for the identification are convincing. According to the second view, it is hopeless to try to evaluate the adequacy of a proposed mathematical characterization of effectiveness, because the intuitive notion is too vague. The analysis undertaken in this thesis conflicts with both views. ;I All classical arguments for Church's thesis, including Turing's, have unconvincing aspects. ;II Some generalizations of Turing's work show that unconvincing aspects of Turing's argument can be dispensed with and provide conceptually significant contributions to the problem of a "natural" mathematical characterization of the mechanically calculable functions. ;III One can isolate meanings of effectiveness conceptually more inclusive than mechanical calculability and distinguish between corresponding interpretations of Church's thesis. ;The analytical work supporting these claims bears significantly on the philosophical issues mentioned above: it plays a crucial role in a philosophical evaluation of the undecidability and incompleteness theorems and in a clarification of the conceptual background of computational approaches in cognitive psychology.

Moral judgment – even the type discussed by Knobe – necessarily relies on substantial information about an agent's mental states, especially regarding beliefs and attitudes. Moreover, the effects described by Knobe can be attributed to norm violations in general, rather than moral concerns in particular. Consequently, Knobe's account overstates the influence of moral judgment on assessments of mental states and causality.

Much of the current research in regenerative medicine concentrates on stem-cell therapy that exploits the regenerative capacities of stem cells when injected into different types of human tissues. Although new therapeutic paths have been opened up by induced pluripotent cells and human mesenchymal cells, the rate of success is still low and mainly due to the difficulties of managing cell proliferation and differentiation, giving rise to non-controlled stem cell differentiation that ultimately leads to cancer. Despite being still far from becoming (...) a reality, these studies highlight the role of physical and biological constraints (e.g., cues and morphogenetic fields) placed by tissue microenvironment on stem cell fate. This asks for a clarification of the coupling of stem cells and microenvironmental factors in regenerative medicine. We argue that extracellular matrix and stem cells have a causal reciprocal and asymmetric relationship in that the 3D organization and composition of the extracellular matrix establish a spatial, temporal, and mechanical control over the fate of stem cells, which enable them to interact and control (as well as be controlled by) the cellular components and soluble factors of microenvironment. Such an account clarifies the notions of stemness and stem cell regeneration consistently with that of microenvironment. (shrink)

In this paper, we report on the development of The Sustainable Port video game, which aims to simulate the complex dynamics and decisions occurring in the present and future development of a port area considering environmental aspects (CO2 emissions) and profit. To evaluate if this game fulfills its purpose, we asked 75 students and 34 employees at the Port of Rotterdam (PoR) to play The Sustainable Port. Our results show that PoR employees score higher than students suggesting a transfer between (...) real-life experience of being an employee in the port and performance in the game. Furthermore, port participants reported that The Sustainable Port can be successfully used to start discussions about the future of the Port of Rotterdam and to raise awareness about the complexity characterizing the decision-making processes occurring in a port environment. Our results, taken together, provide evidence of the effectiveness of The Sustainable Port in simulating dynamics occurring in port development and give us optimism about future applications.

Moral judgments about an agent's behavior are enmeshed with inferences about the agent's mind. Folk psychology—the system that enables such inferences—therefore lies at the heart of moral judgment. We examine three related folk-psychological concepts that together shape people's judgments of blame: intentionality, choice, and free will. We discuss people's understanding and use of these concepts, address recent findings that challenge the autonomous role of these concepts in moral judgment, and conclude that choice is the fundamental concept of the three, defining (...) the core of folk psychology in moral judgment.

Artificial agents are progressively becoming more present in everyday-life situations and more sophisticated in their interaction affordances. In some specific cases, like Google Duplex, GPT-3 bots or Deep Mind’s AlphaGo Zero, their capabilities reach or exceed human levels. The use contexts of everyday life necessitate making such agents understandable by laypeople. At the same time, displaying human levels of social behavior has kindled the debate over the adoption of Dennett’s ‘intentional stance’. By means of a comparative analysis of the literature (...) on robots and virtual agents, we defend the thesis that approaching these artificial agents ‘as if’ they had intentions and forms of social, goal-oriented rationality is the only way to deal with their complexity on a daily base. Specifically, we claim that this is the only viable strategy for non-expert users to understand, predict and perhaps learn from artificial agents’ behavior in everyday social contexts. Furthermore, we argue that as long as agents are transparent about their design principles and functionality, attributing intentions to their actions is not only essential, but also ethical. Additionally, we propose design guidelines inspired by the debate over the adoption of the intentional stance. (shrink)

I offer a framework for impossibility in the legal domain. I argue for two main points: the use of ‘impossibility’ and ‘impossible’ in the legal domain is often incoherent; in the law we often different concepts of impossibility as well as concepts that differ from impossibility that are nonetheless called ‘impossibility’.
