This paper introduces a general logical framework for reasoning about diffusion processes within social networks. The new “Logic for Diffusion in Social Networks” is a dynamic extension of standard hybrid logic, allowing to model complex phenomena involving several properties of agents. We provide a complete axiomatization and a terminating and complete tableau system for this logic and show how to apply the framework to diffusion phenomena documented in social networks analysis.

In many social contexts, social influence seems to be inescapable: the behavior of others influences us to modify ours, and vice-versa. However, social psychology is full of examples of phenomena where individuals experience a discrepancy between their public behavior and their private opinion. This raises two central questions. First, how does an individual reason about the behavior of others and their private opinions in situations of social influence? And second, what are the laws of the resulting information dynamics? In this (...) paper, we address these questions by introducing a formal framework for representing reasoning about an individual’s private opinions and public behavior under the dynamics of social influence in social networks. Moreover, we dig deeper into the involved information dynamics by modeling how individuals can learn about each other based on this reasoning. This compels us to introduce a new formal notion of reflective social influence. Finally, we initialize the work on proof theory and automated reasoning for our framework by introducing a sound and complete tableaux system for a fragment of our logic. Furthermore, this constitutes the first tableau system for the “Facebook logic” of J. Seligman, F. Liu, and P. Girard. (shrink)

We propose a new dynamic hybrid logic to reason about social networks and their dynamics building on the work of “Logic in the Community” by Seligman, Liu and Girard. Our framework distinguishes between the purely private sphere of agents, namely their mental states, and the public sphere of their observable behavior, i.e., what they seem to believe. We then show how such a distinction allows our framework to model many social phenomena, by presenting the case of pluralistic ignorance as an (...) example and discussing some of its dynamic properties.

We study the logic of so-called lexicographic or priority merge for multi-agent plausibility models. We start with a systematic comparison between the logical behavior of priority merge and the more standard notion of pooling through intersection, used to define, for instance, distributed knowledge. We then provide a sound and complete axiomatization of the logic of priority merge, as well as a proof theory in labeled sequents that admits cut. We finally study Moorean phenomena and define a dynamic resolution operator for (...) priority merge for which we also provide a complete set of reduction axioms. (shrink)

We take a logical approach to threshold models, used to study the diffusion of e.g. new technologies or behaviors in social net-works. In short, threshold models consist of a network graph of agents connected by a social relationship and a threshold to adopt a possibly cascading behavior. Agents adopt new behavior when the proportion of their neighbors who have already adopted it meets the threshold. Under this adoption policy, threshold models develop dynamically with a guaranteed fixed point. We construct a (...) minimal dynamic propositional logic to describe the threshold dynamics and show that the logic is sound and complete. We then extend this framework with an epistemic dimension and investigate how information about more distant neighbors’ behaviors allows agents to anticipate changes in behavior of their closer neighbors. It is shown that this epistemic prediction dynamics is equivalent to the non-epistemic threshold model dynamics if and only if agents know exactly their neighbors’ behavior. We further show results regarding fixed points and convergence speed,and provide a partial set of reduction laws, venues for further research, and graphical representations of the dynamics. (shrink)

We take a logical approach to threshold models, used to study the diffusion of opinions, new technologies, infections, or behaviors in social networks. Threshold models consist of a network graph of agents connected by a social relationship and a threshold value which regulates the diffusion process. Agents adopt a new behavior/product/opinion when the proportion of their neighbors who have already adopted it meets the threshold. Under this diffusion policy, threshold models develop dynamically towards a guaranteed fixed point. We construct a (...) minimal dynamic propositional logic to describe the threshold dynamics and show that the logic is sound and complete. We then extend this framework with an epistemic dimension and investigate how information about more distant neighbors’ behavior allows agents to anticipate changes in behavior of their closer neighbors. Overall, our logical formalism captures the interplay between the epistemic and social dimensions in social networks. (shrink)

In this paper, we investigate the social herding phenomenon known as informational cascades, in which sequential inter-agent communication might lead to epistemic failures at group level, despite availability of information that should be sufficient to track the truth. We model an example of a cascade, and check the correctness of the individual reasoning of each agent involved, using two alternative logical settings: an existing probabilistic dynamic epistemic logic, and our own novel logic for counting evidence. Based on this analysis, we (...) conclude that cascades are not only likely to occur but are sometimes unavoidable by "rational" means: in some situations, the group’s inability to track the truth is the direct consequence of each agent’s rational attempt at individual truth-tracking. Moreover, our analysis shows that this is even so when rationality includes unbounded higher-order reasoning powers, as well as when it includes simpler, non-Bayesian forms of heuristic reasoning.

The my-side bias is a well-documented cognitive bias in the evaluation of arguments, in which reasoners in a discussion tend to overvalue arguments that confirm their prior beliefs, while undervaluing arguments that attack their prior beliefs. The first part of this paper develops and justifies a Bayesian model of myside bias at the level of individual reasoning. In the second part, this Bayesian model is implemented in an agent-based model of group discussion among myside-biased agents. The agent-based model is then (...) used to perform a number of experiments with the objective to study whether the myside bias hinders or enhances the ability of groups to collectively track the truth, that is, to reach the correct answer to a given binary issue. An analysis of the results suggests the following: First, whether the truth-tracking ability of groups is helped or hindered by myside bias crucially depends on how the strength of myside bias is differentially distributed across subgroups of discussants holding different beliefs. Second, small groups are more likely to track the truth than larger groups, suggesting that increasing group size has a detrimental effect on collective truth-tracking through discussion. (shrink)

In this paper, I claim that the personal/subpersonal distinction is first and foremost a distinction between two kinds of psychological theory or explanation: it is only in this form that we can understand why the distinction was first introduced, and how it continues to earn its keep. I go on to examine the different ontological commitments that might lead us from the primary distinction between personal and subpersonal explanations to a derivative distinction between personal and subpersonal states. I argue that (...) on one of the most common metaphysical interpretations of the explanatory distinction, talk of a distinction between personal and subpersonal states simply makes no sense. When people insist on applying the personal/subpersonal terminology to psychological states, I allow that they are often making a genuine distinction, but one that it is best understood in terms of Stich's (1978) distinction between doxastic and subdoxastic states. I end the paper by considering some other common misinterpretations of the personal/subpersonal distinction, such as those involving consciousness, normativity, or autonomy. (shrink)

Daniel Dennett's distinction between personal and subpersonal explanations was fundamental in establishing the philosophical foundations of cognitive science. Since it was first introduced in 1969, the personal/subpersonal distinction has been adapted to fit different approaches to the mind. In one example of this, the ‘Pittsburgh school’ of philosophers attempted to map Dennett's distinction onto their own distinction between the ‘space of reasons’ and the ‘space of causes’. A second example can be found in much contemporary philosophy of psychology, where Dennett's (...) distinction has been presumed to be equivalent to Stephen Stich's distinction between doxastic and subdoxastic states. Both these interpretations of the personal/subpersonal distinction, and also Dennett's own philosophical views of the mind, go beyond the personal/subpersonal distinction itself. They each involve supplementing the distinction between personal and subpersonal explanations with metaphysical claims about the relationship between the two kinds of explanation and the entities they posit.

Language provides rich social information about its speakers. For instance, adults and children make inferences about a speaker's social identity, geographic origins, and group membership based on her language and accent. Although infants prefer speakers of familiar languages, little is known about the developmental origins of humans’ sensitivity to language as marker of social identity. We investigated whether 9-month-olds use the language a person speaks as an indicator of that person's likely social relationships. Infants were familiarized with videos of two (...) people who spoke the same or different languages, and then viewed test videos of those two individuals affiliating or disengaging. Results suggest that infants expected two people who spoke the same language to be more likely to affiliate than two people who spoke different languages. Thus, infants view language as a meaningful social marker and use language to make inferences about third-party social relationships. (shrink)

review essay on Gaukroger, Collapse of Mechanism and Rise of Sensibility (OUP).

Summary People with disabilities still show lower participation rates in mainstream sports clubs. Even when they are members of mainstream sports clubs, their participation is often limited to structural integration, while broader social integration including cultural and affective dimensions is only partially achieved. Thus, this study analyses the broader extent of social integration of members with disabilities in sports clubs, applying Esser’s model of social integration, which is comprised of four dimensions: culturation, interaction, identification, and placement. The article describes multiple (...) case studies conducted with this model on a sample of three mainstream clubs, including 14 members with disabilities. Results show overall high scores on the four dimensions, consequently pointing to effective social integration of members with disabilities. Moreover, the studies also reveal indications of factors that are relevant for social integration. This knowledge is helpful for clubs with regard to managing social integration strategies and practices. (shrink)

This paper goes beyond critiques of western philosophical notions of space as passive, feminine, and unintelligent by reconfiguring containment as an active process. The author draws on work in the history of technology, on a cybernetic epistemology that emphasizes the interdependence of organism and environment, and on intersubjectivist psychoanalytic theories of the maternal provision. A more unexpected ally is found in Heidegger, whose writings on holding and supply are read in ways that contribute to the development of an urgently required (...) philosophy of container technologies.

The Religious War of Science. Historical Argumentation in the Academic Speeches of Emil DuBois‐Reymond (1818–1896). Among the protagonists of the “laboratory revolution” (Cunningham/Williams) in 19th‐century physiology were the self‐proclaimed ‘organic physicists’ (“organische Physiker”), who shared a mechanistic conception of life processes. One of their key figures was the physiologist Emil DuBois‐Reymond (1818–1896) who not only excelled in the field of neuroscience but also became known, over the decades of his active career, as an orator at the Berlin Academy of Sciences (...) and Humanities. In his academic speeches, DuBois‐Reymond regularly commemorated heroes of the history of science. On closer inspection, these references went far beyond paying the usual homage to precursors: This paper argues that DuBois‐Reymond made use of episodes from the history of science as a means to legitimate his own reductionist research programme and, at the same time, decry idealistic natural philosophy and vitalistic positions. Drawing upon biblical rhetorics, DuBois‐Reymond systematically construed experimental physiology as the culmination of a teleological development, and, hence, organic physicists as the incarnation of scientific ‘redeemers’. According to him, the success of ‘organic physics’ displayed the peak of an inevitable development. (shrink)

This article examines the early modern household's importance for producing experimental knowledge through an examination of the Halifax household of Margery and Henry Power. While Henry Power has been studied as a natural philosopher within the male-dominated intellectual circles of Cambridge and London, the epistemic labour of his wife, Margery Power, has hitherto been overlooked. From the 1650s, this couple worked in tandem to enhance their understanding of the vegetable world through various paper technologies, from books, paper slips and recipe (...) notebooks to Margery's drawing album and Henry's published Experimental Philosophy. Focusing on Margery's practice of hand-colouring flower books, her copied and original drawings of flowers and her experimental production of ink, we argue that Margery's sensibility towards colour was crucial to Henry's microscopic observations of plants. Even if Margery's sophisticated knowledge of plants never left the household, we argue that her contribution was nevertheless crucial to the observation and representation of plants within the community of experimental philosophy. In this way, our article highlights the importance of female artists within the history of scientific observation, the use of books and paperwork in the botanical disciplines, and the relationship between household science and experimental philosophy.

This paper investigates the relationship between economic theory and theories of justice in the design of public policy. In particular, it focuses on the role of mechanism design in policy contexts beset with issues of social, racial and distributive justice. Economists’ involvement in redesigning Boston’s algorithm for allocating K-12 students to public schools serves as an instructive case study. The paper draws on the distinction betweenideal theoryandnon-ideal theoryin political philosophy and the concept ofperformativityin economic sociology to argue that mechanism design (...) can enact elaborate ideal theories of justice. Anormative gapthus emerges between the goals of the policymakers and the objectives of economic designs. As a result, mechanism design may obstruct stakeholders’ avenues for normative criticism of public policies, and serve as a technology of depoliticization. (shrink)

The use of genetically modified organisms in agriculture makes great promises of better seeds, but also raises many controversies about ownership of seeds and about potential hazards. I suggest that owners of these seeds bear the responsibility to do no harm in using these seeds. After defining the nature of this responsibility, this paper asks, if ownership entails moral responsibility, and ownership can be transferred, then how is moral responsibility transferred? Building on the literature on use plans, I suggest five (...) conditions for a good transfer of moral responsibility for genetically modified seeds. I also look at the Monsanto Technology Use Guide and Technology/Stewardship Agreement, as an examplar of a use plan, to explore the extent to which these conditions are present. I conclude that use plans can play a role in the distribution and transfer of moral responsibility for technologies with high benefits and potential harmful uncertainties. (shrink)

This paper explores the relationship between several ideas about the mind and cognition. The hypothesis of extended cognition claims that cognitive processes can and do extend outside the head, that elements of the world around us can actually become parts of our cognitive systems. It has recently been suggested that the hypothesis of extended cognition is entailed by one of the foremost philosophical positions on the nature of the mind: functionalism, the thesis that mental states are defined by their functional (...) relations rather than by their physical constituents. Furthermore, it has been claimed that functionalism entails a version of extended cognition which is sufficiently radical as to be obviously false. I survey the debate and propose several ways of avoiding this conclusion, emphasizing the importance of distinguishing the hypothesis of extended cognition from the related notion of the extended mind.

In this essay, I study the contested role of magnification as an observational strategy in the generation theories of William Harvey and René Descartes. During the seventeenth century, the grounds under the discipline of anatomy were shifting as knowledge was increasingly based on autopsia and observation. Likewise, new theories of generation were established through observations of living beings in their smallest state. But the question formed: was it possible to extend vision all the way down to the first points of (...) life? Arguing that the potential of magnification hinged on the metaphysics of living matter, I show that Harvey did not consider observational focus on the material composition of blood and embryos to be conducive to knowledge of living bodies. To Harvey, generation was caused by immaterial, and thus in principle invisible, forces that could not be magnified. Descartes, on the other hand, believed that access to the subvisible scale of natural bodies was crucial to knowledge about their nature. This access could be granted through rational introspection, but possibly also through powerful microscopes. The essay thus ends with a reflection on the importance of Cartesian corpuscularianism for the emergence of microscopical anatomy in seventeenth-century England. (shrink)

The past twenty years have seen an increase in the importance of the body in psychology, neuroscience, and philosophy of mind. This 'embodied' trend challenges the orthodox view in cognitive science in several ways: it downplays the traditional 'mind-as-computer' approach and emphasizes the role of interactions between the brain, body, and environment. In this article, I review recent work in the area of embodied cognitive science and explore the approaches each takes to the ideas of consciousness, computation and representation. Finally, (...) I look at the current relationship between orthodox cognitive science and the study of mental disorder, and consider the implications that the embodied trend could have for issues in psychopathology.

Testimonial accounts of mathematical problem choice typically rely on intrinsic constraints. They focus on the worth of the problem and feelings of beauty. These are often developed as both descriptive and normative constraints on problem choice.

A number of elements for the relationship between mathematician and his audience make up this contact. This constraint stems from the (...) mathematician’s role as an arguer, as one of the pre-requisites to argumentation is contact of minds. I examine two exceptional cases which fail to be explained by intrinsic constraints on motivation and posit how this contact could influence usual cases. While not the only constraint or drive in problem choice, establishing contact of minds plays an important role worth further examination. (shrink)

Church has contributed a lot to the safeguard of G. Frege's theory of meaning after the discovery of antinomies in it. To achieve this he has adapted it by keeping parts, discarding others and adding new ones, most of which are clearly exposed in an informal way in the introduction to his Introduction to Mathematical Logic. As for any modification of a theory by another person, it is interesting to understand how the thoughts of the former survive in the new (...) theory even though radical changes have occurred, or on the contrary how it retains only the appearance of the initial theory. We shall therefore go through the basic concepts of logic he introduces in this introduction and assess their relation to Frege's original theory. (shrink)

Individuals with chronic pain often experience co-existing sleep problems and depression-related states. Chronic pain, sleep problems, and depression interrelate, and have been shown to exacerbate one another, which negatively impacts quality of life. This study explored the relationships between pain severity, pain interference, sleep quality, and depression among individuals with chronic pain. Secondly, we tested whether sleep quality may moderate the relationship between pain and depression. A cross-sectional survey was completed by 1,059 adults with non-malignant chronic pain conditions and collected (...) measures related to pain severity, pain interference, sleep quality, and depression. Multiple regression analyses found that pain severity, pain interference, and sleep quality are all significantly associated with depression. Secondly, moderated regression analyses revealed that sleep quality moderates the relationship between pain interference and depression among individuals with chronic pain such that good sleep quality attenuates the effect of pain interference on depression, and poor sleep quality amplifies the effect of pain interference on depression. These findings suggest that sleep quality may be a relevant therapeutic target for individuals with chronic pain and co-existing depression. (shrink)

In August of 1971, President Nixon announced that the United States was “closing the gold window,” bringing an end to the postwar system of international exchange rate stability and precipitating a period of significant uncertainty and transformation in global institutions. Although this critical historical episode is important for an understanding of historical “neoliberalism” and institutional change, modern sociological perspectives have scarcely been applied to it. The present analysis uses archival data to show that closing the gold window was never the (...) goal or preferred strategy of the Nixon administration, which had spent years preparing much more modest reforms. Nevertheless, US policymakers took this unilateral action as a contingency plan to achieve a short-term goal, knowing that it would dramatically change the functioning of the international economy. Surprisingly, the autonomous structure of the IMF did not channel US initiatives toward gradual evolution but rather helped determine a radical change in strategy. (shrink)

The “received wisdom” in contemporary analytic philosophy is that intuition talk is a fairly recent phenomenon, dating back to the 1960s. In this paper, we set out to test two interpretations of this “received wisdom.” The first is that intuition talk is just talk, without any methodological significance. The second is that intuition talk is methodologically significant; it shows that analytic philosophers appeal to intuition. We present empirical and contextual evidence, systematically mined from the JSTOR corpus and HathiTrust’s Digital Library, (...) which provide some empirical support for the second rather than the first hypothesis. Our data also suggest that appealing to intuition is a much older philosophical methodology than the “received wisdom” alleges. We then discuss the implications of our findings for the contemporary debate over philosophical methodology. (shrink)

Perceptual experiences are not immediately responsive to reasons. You see a stick submerged in a glass of water as bent no matter how much you know about light refraction. Due to this isolation from reasons, perception is traditionally considered outside the scope of epistemic evaluability as justified or unjustified. Is perception really as independent from reasons as visual illusions make it out to be? I argue no, drawing on psychological evidence from perceptual learning. The flexibility of perceptual learning is a (...) way of responding to new epistemic reasons. The resulting perceptual experiences are epistemically evaluable as justified or unjustified. (shrink)

Many philosophers subscribe to the view that philosophy is a priori and in the business of discovering necessary truths from the armchair. This paper sets out to empirically test this picture. If this were the case, we would expect to see this reflected in philosophical practice. In particular, we would expect philosophers to advance mostly deductive, rather than inductive, arguments. The paper shows that the percentage of philosophy articles advancing deductive arguments is higher than those advancing inductive arguments, which is (...) what we would expect from the vantage point of the armchair philosophy picture. The results also show, however, that the percentages of articles advancing deductive arguments and those advancing inductive arguments are converging over time and that the difference between inductive and deductive ratios is declining over time. This trend suggests that deductive arguments are gradually losing their status as the dominant form of argumentation in philosophy. (shrink)

Chapter 8 argues against the view that the moral rightness of an act is not a reason to perform it, and our reasons are instead the features that make the act right. Philosophers typically defend this view by noting that it seems redundant to take rightness to be an additional reason, once it has been acknowledged that the right-making features are already reasons. The author shows that this argument dramatically overgeneralizes, ruling out all cases in which two or more reasons (...) are arranged in relationships of metaphysical constitution. She then proposes an alternative way of thinking about these metaphysical hierarchies: Rather than assuming that at most one of the facts in each hierarchy is the “real” reason, bearing all the normative weight, it should be accepted that these facts can all be genuine reasons, whose normative weight is shared in virtue of the metaphysical relationships between them. Some tests are offered that can be used to determine which facts occur in metaphysical hierarchies with shared weight, and it is argued that the fact that an act is morally right passes the tests. The author then explains what she takes to be some kernels of truth underlying the redundancy argument, arguing that these phenomena are pragmatic, not metaphysical. (shrink)

Is theistic evolution (TE) a philosophically tenable position? Leidenhag argues in his article “The Blurred Line between Theistic Evolution and Intelligent Design” that it is not, since it, Leidenhag claims, espouses a view of divine action that he labels “natural divine causation” (NDC), which makes God explanatory redundant. That is, in so far as TE does not invoke God as an additional cause alongside natural causes, it is untenable. Theistic evolutionists should therefore “reject NDC and affirm a more robust notion (...) of divine agency.” However, this will, Leidenhag claims, have the effect that theistic evolutionists “will move their position significantly closer to Intelligent Design,” and so the line between TE and intelligent design is (or ought to be?) blurred. If successful, the criticism by Leidenhag would be bad news for theists who want to take science seriously and good news for those scientistic atheists according to whom there simply is no scientifically respectable way of combining theism and modern natural science in an overarching worldview. So, is TE stuck between a rock (of redundancy) and a hard place (of pseudo‐science)? No, at least not due to the criticism offered by Leidenhag—but maybe religious naturalism is? (shrink)

The idea of an inevitable conflict between science and religion leading to relentless hostility between the two emerged in the nineteenth century and has become a powerful narrative of modernity. Most historians of science trace the origins of the so-called ‘conflict thesis’ to the English-speaking world, more precisely to scientist-historian John William Draper and literary scholar Andrew Dickson White. Their books on the history of scientific-religious conflict turned into bestsellers. Yet, if we look beyond the Anglo-American world, the conflict thesis (...) appears in new historical settings. This paper argues that the science vs. religion narrative flourished already in Germany before Draper and White announced the warfare between science and religion in England and the USA. Focusing on Germany, we aim to show that the conflict thesis emerged in a polycentric process shaped by various political, cultural, and social struggles. It became a rhetorical weapon for liberal scientists in Germany to oppose Ultramontanism and, at the same time, to discredit their rivals as unscientific, fanatic, or even as ‘henchmen’ of the Pope. Our paper makes a case for a decentred approach to the history of the conflict thesis, which brings to the fore specific political and cultural tensions shaping this narrative in the nineteenth century.

According to a traditional picture, perception and belief have starkly different epistemic roles. Beliefs have epistemic statuses as justified or unjustified, depending on how they are formed and maintained. In contrast, perceptions are “unjustified justifiers.” Core cognition is a set of mental systems that stand at the border of perception and belief, and has been extensively studied in developmental psychology. Core cognition's borderline states do not fit neatly into the traditional epistemic picture. What is the epistemic role of these states? (...) Focusing on the core object system, the author argues that core object representations have epistemic statuses like beliefs do, despite their many prototypically perceptual features. First, the author argues that it is a sufficient condition on a mental state's having an epistemic status as justified or unjustified that the state is based on reasons. Then the author argues that core object representations are based on reasons, through an examination of both experimental results and key markers of the basing relation. The scope of mental states that are subject to epistemic evaluation as justified or unjustified is not restricted to beliefs. (shrink)

The author, an ordained Lutheran pastor, reflects upon his experiences as chaplain at a small hospital in southwestern Germany (Tropenklinik – Paul Lecher Krankenhaus, Tübingen). Besides its expertise in the treatment of tropical diseases this 100 + bed hospital serves as the referral hospital for terminally ill and dying patients from the local University hospitals and the surrounding area.

They made him to discover three essentials as the very basis of such ministry, which he shares in this article.

Modular approaches to the architecture of the mind claim that some mental mechanisms, such as sensory input processes, operate in special-purpose subsystems that are functionally independent from the rest of the mind. This assumption of modularity seems to be in tension with recent claims that the mind has a predictive architecture. Predictive approaches propose that both sensory processing and higher-level processing are part of the same Bayesian information-processing hierarchy, with no clear boundary between perception and cognition. Furthermore, it is not (...) clear how any part of the predictive architecture could be functionally independent, given that each level of the hierarchy is influenced by the level above. Both the assumption of continuity across the predictive architecture and the seeming non-isolability of parts of the predictive architecture seem to be at odds with the modular approach. I explore and ultimately reject the predictive approach’s apparent commitments to continuity and non-isolation. I argue that predictive architectures can be modular architectures, and that we should in fact expect predictive architectures to exhibit some form of modularity. (shrink)

Perception provides us with access to the external world, but that access is shaped by our own experiential histories. Through perceptual learning, we can enhance our capacities for perceptual discrimination, categorization, and attention to salient properties. We can also encode harmful biases and stereotypes.

Perceptual learning raises the possibility that our inquiries into topics such as epistemic justification, aesthetic criticism, and (...) moral knowledge should include not only an examination of cognition but also of perception.

Safe-by-design aims at addressing safety issues already during the R&D and design phases of new technologies. SbD has increasingly become popular in the last few years for addressing the risks of emerging technologies like nanotechnology and synthetic biology. We ask to what extent SbD approaches can deal with uncertainty, in particular with indeterminacy, i.e., the fact that the actual safety of a technology depends on the behavior of actors in the value chain like users and operators. We argue that while (...) indeterminacy may be approached by designing out users as much as possible in attaining safety, this is often not a good strategy. It will not only make it more difficult to deal with unexpected risks; it also misses out on the resources that users can bring for achieving safety, and it is undemocratic. We argue that rather than directly designing for safety, it is better to design for the responsibility for safety, i.e., designers should think where the responsibility for safety is best situated and design technologies accordingly. We propose some heuristics that can be used in deciding how to share and distribute responsibility for safety through design. (shrink)
