Self-reported data are regarded by medical researchers as invalid and less reliable than data produced by experts in clinical settings, yet individuals can increasingly contribute personal information to medical research through a variety of online platforms. In this article we examine this ‘participatory turn’ in healthcare research, which claims to challenge conventional delineations of what is valid and reliable for medical practice, by using aggregated self-reported experiences from patients and ‘pre-patients’ via the internet. We focus on 23andMe, a genetic testing (...) company that collects genetic material and self-reported information about disease from its customers. Integral to this research method are relations of trust embedded in the information exchange: trust in customers’ data; trust between researchers/company and research subjects; trust in genetics; trust in the machine. We examine the performative dimension of these trust relations, drawing on Shapin and Schaffer’s discussion of how material, literary and social technologies are used in research in order to establish trust. Our scepticism of the company’s motives for building trust with the self-reporting consumer forces us to consider our own motives. How does the use of customer data for research purposes by 23andMe differ from the research practices of social scientists, especially those who also study digital traces? By interrogating the use of self-reported data in the genetic testing context, we examine our ethical responsibilities in studying the digital selves of others using internet methods. How researchers trust data, how participants trust researchers, and how technologies are trusted are all important considerations in studying the social life of digital data. (shrink)

Analytic debates about truth are wide-ranging, but certain key themes tend to crop up time and again. The three themes that we will examine in this paper are (i) the nature and behaviour of the ordinary concept of truth, (ii) the meaning of discourse about truth, and (iii) the nature of the property truth. We will start by offering a brief overview of the debates centring on these themes. We will then argue that cross-linguistic experimental philosophy has an indispensable yet (...) underappreciated role to play in all of these debates. Recognising the indispensability of cross-linguistic experimental philosophy should compel philosophers to significantly revise the ways in which they inquire about truth. It should also prompt analytic philosophers more generally to consider whether similar revisions might be necessary elsewhere in the field. (shrink)

Mistrust and fear of research often exist in minority communities because of assumptions, preconceived ideas, and historical abuse and racism that continue to influence research participation. The research establishment is full of well-meaning ‘outsider’ investigators who recognize discrimination, health disparities, and insufficient health care providers in minority communities, but struggle in breaking through this history of mistrust. This article provides ethical insights from one such ‘insider-outsider’, community-based participatory research project implemented via community health advisors in the Mississippi Delta. Both community-based (...) participatory research and community health advisors provide opportunities to address the ethical issues of trust, non-maleficence, and justice in minority communities. Implications for ethics-driven nursing research are discussed. (shrink)

This article introduces the special issue on middle-range theory in science and technology studies, providing the background to its production and reviewing different notions of “middle.” It begins with Merton's ideas about middle-range theory as a way of moving beyond the production of either descriptions or theories of everything. Instead of seeing the middle as the space between the theoretical imagination and the detailed depiction of everyday practices, the authors outline three ways of thinking about the middle range: as an (...) adjective, the closest to Merton's conception; as a noun, the liminal place between theories, audiences, and levels; and as a verb, a process, a means of making connections across time, discipline, community, and place. A summary of each of the articles in this special issue is provided, preceding a call for further discussion about the role of case studies and the nature of the middle in STS. (shrink)

According to the restructuring hypothesis, insight problem solving typically progresses through consecutive stages of search, impasse, insight, and search again for someone, who solves the task. The order of these stages was determined through self-reports of problem solvers and has never been verified behaviorally. We asked whether individual analysis of problem solving attempts of participants revealed the same order of problem solving stages as defined by the theory and whether their subjective feelings corresponded to the problem solving stages they were (...) in. Our participants tried to solve the Five-Square problem in an online task, while we recorded the time and trajectory of their stick movements. After the task they were asked about their feelings related to insight and some of them also had the possibility of reporting impasse while working on the task. We found that the majority of participants did not follow the classic four-stage model of insight, but had more complex sequences of problem solving stages, with search and impasse recurring several times. This means that the classic four-stage model is not sufficient to describe variability on the individual level. We revised the classic model and we provide a new model that can generate all sequences found. Solvers reported insight more often than non-solvers and non-solvers reported impasse more often than solvers, as expected; but participants did not report impasse more often during behaviorally defined impasse stages than during other stages. This shows that impasse reports might be unreliable indicators of impasse. Our study highlights the importance of individual analysis of problem solving behavior to verify insight theory. (shrink)

Wie verändern sich Mensch und Körper durch Technik? Und welches Menschenverständnis vertritt der Transhumanismus? Anna Puzio befasst sich in der ersten philosophischen Studie zur Anthropologie des Transhumanismus mit führenden Personen des Feldes, u. a. mit Nick Bostrom, David Pearce und Natasha Vita-More. Neben Körperoptimierung und Medizintechnologien beleuchtet sie auch Alltagstechnologien wie Wearables. Dabei entwickelt sie einen neuen Ansatz zur Technikanthropologie und ein neues inklusives Menschen- und Körperverständnis im Anschluss an Donna Haraway und den Kritischen Posthumanismus im amerikanischen Raum.

This book intervenes in the field of intersectionality studies: the integrative examination of the effects of racial, gendered, and class power on people’s lives. While “intersectionality” circulates as a buzzword, Anna Carastathis joins other critical voices to urge a more careful reading. Challenging the narratives of arrival that surround it, Carastathis argues that intersectionality is a horizon, illuminating ways of thinking that have yet to be realized; consequently, calls to “go beyond” intersectionality are premature. A provisional interpretation of intersectionality (...) can disorient habits of essentialism, categorial purity, and prototypicality and overcome dynamics of segregation and subordination in political movements. -/- Through a close reading of critical race theorist Kimberlé Williams Crenshaw’s germinal texts, published more than twenty-five years ago, Carastathis urges analytic clarity, contextual rigor, and a politicized, historicized understanding of this widely traveling concept. Intersectionality’s roots in social justice movements and critical intellectual projects—specifically Black feminism—must be retraced and synthesized with a decolonial analysis so its radical potential to actualize coalitions can be enacted.

Research integrity climate is an important factor that influences an individual’s behavior. A strong research integrity culture can lead to better research practices and responsible conduct of research. Therefore, investigations on organizational climate can be a valuable tool to identify the strengths and weaknesses of each group and develop targeted initiatives. This study aims to assess the perceptions on integrity climate in three universities in Hungary. A cross-sectional study was conducted with PhD students, postdocs, and professors from three Hungarian universities. (...) The survey included demographic questions, such as gender, age, scientific field, academic rank, and the Survey of Organizational Research Climate. A total of 432 participants completed the survey. Our results show that postdocs and assistant professors perceived integrity climate more negatively than PhD students and full professors in every survey scale. Contrarily, PhD students perceive more positively than the other groups. Disciplinary differences show that researchers in the Biomedical sciences perceive regulatory bodies to be fairer when evaluating their projects than those in the Natural sciences. Natural sciences also perceive more negatively how the department values integrity when compared to Humanities. Humanities perceive more positively Advisor/Advisee Relations than Biomedical Sciences. Our results suggest that institutions should pay more attention to early career researchers, especially insecure and temporary positions like postdocs and assistant professors. They should provide RCR resources, socialize them in RCR, and set more reasonable expectations. Moreover, department leaders should develop initiatives to foster better integrity climates. (shrink)

Definition of the problemThe medical-ethical principle of beneficence is directed towards the well-being of patients. In clinical practice, the focus is often on the relief of pain, the elimination of symptoms and the restoration of bodily functioning. However, the significance of these health-related aspects for the overall well-being of patients also depends on individual values, desires, and life plans.ArgumentationAn overemphasis on the subjective perspective of patients on their well-being would admittedly lead to a strong substantial convergence of the two medical-ethical (...) principles of beneficence and respect for autonomy. In addition, it would not be compatible with some of the guiding principles of the medical profession. A mere objective perspective on patient well-being conversely carries the danger of imposing values on individual patients that they do not share. Consequently, actions that are intended to benefit patients instead harm them.ConclusionThrough a more detailed analysis of the relationship between health-related and overall well-being, this paper shows that health is only a relative value in our overall well-being. Basic health-related goods like a sound cardiovascular system or fully functioning lungs have special standing because they are seen as valuable independently of individual preferences and life plans, which means they are of objective value.

The growing abundance of medical technologies has led to laments over doctors’ sensory de-skilling, technologies viewed as replacing diagnosis based on sensory acumen. The technique of percussion has become emblematic of the kinds of skills considered lost. While disappearing from wards, percussion is still taught in medical schools. By ethnographically following how percussion is taught to and learned by students, this article considers the kinds of bodies configured through this multisensory practice. I suggest that three kinds of bodies arise: skilled (...) bodies; affected bodies; and resonating bodies. As these bodies are crafted, I argue that boundaries between bodies of novices and bodies they learn from blur. Attending to an overlooked dimension of bodily configurations in medicine, self-perception, I show that learning percussion functions not only to perpetuate diagnostic craft skills but also as a way of knowing of, and through, the resource always at hand; one’s own living breathing body.

Mainly known for its links to the periodical market and radical politics, this article recontextualizes the editorship of William Nicholson (1753–1815) in terms of its roots in the metropolitan natural philosophical circles of the second half of the 18th century as well as its impact on experimenters and men of science after 1797. The article argues that Nicholson's editorship of the Journal of Natural Philosophy, Chemistry, and the Arts was a means to expand his philosophical significance among natural philosophers at (...) home and abroad—and was, in fact, a form of epistemological subversion that challenged the “Banksian Learned Empire.”.

ABSTRACT In this survey we have investigated the experiences and attitudes of Danish physicians regarding end‐of life decisions. Most respondents have made decisions that involve hastening the death of a patient, and almost all find it acceptable to do so. Such decisions are made more often, and considered ethically more acceptable, with the informed consent of the patient than without. But both non‐resuscitation decisions, and decisions to provide pain relief in doses that will shorten the patient's life, have been made (...) and found acceptable by at least 50% of the respondents, even when there is no informed consent. Furthermore, 12% have doubled morphine dosages with fixed intervals, thus providing doses substantially higher than that necessary to control pain, without the informed consent of the patient. Two per cent have helped in assisted suicide, and 5% have administered a lethal injection at the patient's request. Respectively 37% and 34% find these last two practices ethically acceptable. Amongst those that do not find them acceptable, the most important reasons to be opposed are, the doctrine of double effect, the doctrine of doing and allowing, and the view that human life is sacred. Amongst supporters, the most important reasons mentioned are, that the patient's right to self‐determination should be respected, the view that a patient should not be forced to suffer, and the view that the patient has a right to be helped to a dignified death.

In March 1986, a public symposium took place in Heidelberg about the “unresolved potential dangers of genetic engineering”. The event was organized by institutions affiliated with the environmental movement. Choosing this symposium as an example, the article shows how the public appearance of scientists can be understood as a form of political activism. The article shows how specialists from fields as diverse as biology, chemistry, physics, law and political sciences tried to place political messages by putting themselves in the limelight (...) as independent scientists. I argue that the symposium was both: a place of science communication intertwined with political agitation that, as should be noted, happened in a time when the West German government was working on the legislation of genetic engineering, legitimated by relying on independent expertise. It can be concluded that the discourse of scientific independence became a strategic tool in the controversial debate about the uses and dangers of genetic engineering. Thus, it draws attention to a dimension of political-scientific activity which cannot be fully grasped by the concept of ‘the expert’ that is established in the history of science. (shrink)

We will, we will oust you! —Lyrics of a chant at a Chicago protest rally, July 8, 20202 On July 8, 2020, in front of the Philippine Consulate of Chicago, a group of activists representing multiple transnational organizations committed to the pursuit of democracy, participated in a Global Day of Action against an Anti-Terrorism Law (ATL) passed in the Philippines five days earlier. This particular rally was led by fierce student and community organizers and workers who loudly proclaimed their opposition to President Rodrigo Duterte’s misogynistic and fascist measures. The epigraph 1. The people, the nation—today they fight / Today they fight—the people, the nation. 2. Song written by Charmaine Balisalisa. 490 Anna Romina Guevarra and Maya Arcilla above captures the lyrics of one young activist’s chant directed at Duterte and choreographed to the tune of Queen’s “We will Rock You.” People followed her steps and gestures rhythmically and in unison, accompanying her chant with sounds from a gangsa (gong), bells, a skateboard tapping the ground, and an empty bucket. There have been multiple protests denouncing Duterte since he assumed power in 2016, but on this particular day, the sense of outrage and urgency was especially palpable in the face of this new law aimed at suppressing dissent. This legislation marked a high point in Duterte’s efforts to exert authoritarian control, and it is significant that opposition to his regime has taken on a specifically feminist character. The Philippines Anti-Terrorism Act of 2020 (Republic Act No. 11479), signed into law on July 3, 2020, amends the Philippines Human Security Act of 2007 by expanding the government’s power and scope for defining what constitutes “terrorism.” It consolidates power through the creation of an Anti-Terrorism Council (ATC) appointed by the President and empowered to act without oversight from the judiciary or legislature. The ATC can order mass arrests without warrants and detain individuals without due process for the mere suspicion of being involved in “terrorist” activities. This Law violates the Philippine Constitution’s Bill of Rights by eliminating free speech, violating the people’s right to privacy, and criminalizing individuals on suspicion of wrongdoing. As the law stipulates, anyone involved in “creating an atmosphere and spreading a message of fear” and “provoking or influencing by intimidation the government or any of its international organizations” will be construed as inciting terrorism. Indeed, this law will continue to erode democratic governance in the country, with some labeling it a “stealth declaration of martial law.”3 As US Congressional Representative Jan Schakowsky (D-IL) noted at the press conference she convened on July 15 to publicly call for the Anti-Terrorism Law’s repeal, “this law represents a new weapon in the administration’s campaign to suppress dissent and will worsen attacks on ordinary people.” 3.

The paper questions the view that the alleged lack of autonomy displayed by certain practices and cultural behavior may constitute a sound justification for limiting toleration of those practices. Not only is the concept of autonomy open to endless controversy, but it also entails a conflict with liberal public morality and often nurtures double standards. To this end, the paper first examines the assumptions and basis of the lack-of-autonomy approach; this analysis perforce leads the author to unravel the notion of (...) autonomy and its rival conceptions. Second, it will be argued that liberal and democratic politics, though indebted to the value of personal autonomy in a fashion, requires only a purely political principle of autonomy. It is also contended that if comprehensive notions of autonomy are used instead of a purely political conception, unacceptable consequences for the public morality of liberal democracy may follow. Finally, the point will be illustrated with some examples drawn from multicultural politics. (shrink)

Although the moral foundations of voting rights regulations have been the subject of widespread scrutiny, there is one aspect of the debate which has gone largely unquestioned and is currently accepted in every state’s actual voting rights regulations. This is the requirement of prior residence, which stipulates that immigrants are granted the right to vote only once they have lived in the host country for a certain period of time. It is this requirement I call into question in this paper. (...) Taking up the most plausible justifications for this requirement, I aim to put substantial pressure on its moral acceptability by arguing that it is not directly grounded by any of the principles that are currently defended as a means to determine the demos, nor a proxy for some other morally relevant feature, nor a warrantor for abilities held to be significant for the right to vote.

Background Older patients are often vulnerable and highly dependent on healthcare professionals’ assessment in the event of acute illness. In the context of ambulance services, this poses challenges as the assessment is normally conducted with a focus on identifying life-threatening conditions. Such assessment is not fully satisfactory in a patient relationship that also aims to promote and protect patient autonomy. Aim To describe ambulance clinicians’ understanding of older patients’ self-determination when the patient’s decision-making ability is impaired. Research design A qualitative (...) design with an inductive approach, guided by descriptive phenomenology. Participants In total, 30 ambulance clinicians, comprised of 25 prehospital emergency nurses, 1 nurse and 4 emergency medical technicians participated in 15 dyadic interviews. Ethical considerations The research was conducted in accordance with the Declaration of Helsinki, and permission was granted by the Swedish Ethical Review Authority. Findings The findings are presented in two themes: (1) Movement between explicit and implicit will; and (2) Contradictions about the patient’s best interests. The clinicians’ interpretations are based on an understanding of the patient’s situation using substitute decision-making in emergency situations and conversations that reveal the patient’s explicit wishes. Sometimes the clinicians collaborate to validate the patient’s implicit will, while they at other times subordinate themselves to others’ opinions. The clinicians find themselves in conflict between personal values and organisational values as they try to protect the patient’s self-determination. Conclusion The results indicate that older patients with an impaired decision-making ability risk losing the right to self-determination in the context of ambulance services. The clinicians face challenges that significantly affect their ability to handle the older patient’s unique needs based on a holistic perspective and their ability to be autonomous. (shrink)

This article locates a theoretical reflection on the form of legal subjectivity against twenty-first century complexities and pressures, including the structural complexities visible in biotechnological developments, new hybridities and numerous contemporary theoretical and practical manifestations of heterogeneity, multiplicity and complexity emerging in a range of disciplines, including cybernetics, techno-theory, post-humanism and ecology. The author defends the theoretical and critical utility of understanding the legal subject as an explicit (and explicitly limited ) constructus . Criticising the constructed naturalism (and the historical (...) and contemporary exclusions) of the 'human being' of law, the author suggests that the language and concept of the 'legal entity' (rather than that of the 'legal person') draws attention to the patterned 'gap' between law and life (and to related injustices enacted by the form of the materialisation of legal subjectivity) while simultaneously providing the degree of theoretical plasticity now required by the mutable complexities of the twenty-first century and beyond.

In lieu of an abstract, here is a brief excerpt of the content:Graffiti and Colonial Unknowing:A Comment on Mishuana Goeman's "Caring for Landscapes of Justice in Perilous Settler Environments"Anna Cookin "caring for landscapes of justice in Perilous Settler Environments," Dr. Goeman shows how the NDN Collective's initiatives, Chemehuevi photographer Cara Romero's Tongvaland project, and the works of Gabrieliño Tongva artist Mercedes Dorame "exemplify communities of care" that work toward "the unmapping of settler terrains" ("Caring for Landscapes" 51). Her address (...) highlights how these cartographic art productions are processes of (re)mapping that challenge colonial spatialities. Drawing on Michi Saagig Nishnaabeg scholar Leanne Betasamosake Simpson's poem "i am graffiti," Goeman frames these art works as Indigenous graffiti, insofar as they are everyday acts of resurgence1 that resist erasure and enact rematriation.My comments aim to articulate how Romero's and Dorame's works both reveal and disrupt a colonial unknowing by showing the cracks of settler colonial spatiality. I take Goeman's address to illustrate that the changing of minds and unsettling of settler identity will not occur through argumentation, facts, and figures alone, but rather through aesthetic and cartographic practices that "provide a way of seeing Indigenous futurities and relationalities" ("Caring for Landscapes" 52).Maps as Tools of Settler ColonialismIn order to highlight how these art practices enact a kind of (re)mapping that breaks through the veneer of colonial permanence, we first need to consider the way mapping transforms land into property in the service of Indigenous erasure and land dispossession. In her address, Goeman offers a short history of what is now called Los Angeles through the lens of dispossession that occurs through "international claiming of property and burgeoning US property law" ("Caring for Landscapes" 53). Tovaangar was divided into Spanish (and [End Page 64] then Mexican) land grants that, after 1846, were "registered under the US as property" (Goeman, "Caring for Landscapes" 53; emphasis added). The Land Act of 1851 "established the domestication of the California landscape under US governance" by legitimating existing Mexican land rights and mapping out territory yet "unclaimed" ("Caring for Landscapes" 54). The mapping of this so-called "unclaimed" territory propelled a violent erasure of California Indians by "establishing new and ongoing commerce centers" ("Caring for Landscapes" 53). Land was transferred into property—as a thing owned—without "the consent of those who … lived on the land since time immemorial, following the settler structure of passing land between Christian nations" ("Caring for Landscapes" 53). By showing how property rights legitimate conquest and violence, Goeman illustrates how mapping has been (and continues to be) an "essential settler-colonial tool to domesticate land in Southern California and propel development" ("Caring for Landscapes" 54). While she demonstrates how the mapping of Tovaangar using 493 hand-drawn Diseños maps served to sever Indigenous communities (and their relationships with land, such as the Gabrieliño Tongva with the San Gabriel Mountains), she emphasizes that this is an ongoing process that has not been left in a distant past. Newer maps that may seem more objective and scientific with "better models of scale or a more realist representation" remain, at their core, maps of dispossession ("Caring for Landscapes" 54).The very desire to objectively determine location by assigning latitude and longitude reveals a colonial spatiality, which "territorialize[s] the physical landscape by manufacturing categories and separating land from people" and conceives of space in terms of property logics (Goeman, "[Re]Mapping Indigenous Presence" 296). In addition to Indigenous land dispossession, this colonial spatiality rejects relationality by creating dualist boundaries between human and non-human, in which land is the raw material for human development and the creation of culture. Cherokee philosopher Brian Burkhart speaks of relationality in terms of locality, which he defines as "being-fromthe-land, knowing-from-the-land, and meaning-from-the-land" (Indigenizing Philosophy xvii). The severing of locality can be understood in terms of the transformation of land as relative to inert matter to be acted upon. Mapping serves as a tool of settler colonial erasure insofar as it delocalizes "land as the relational ground of kinship" into "land as a mere object that only has meaning or value in relation to people" ("Indigenizing Philosophy...

In this paper, I revisit Kimberlé Crenshaw's argument in “Demarginalizing the Intersection of Race and Sex” (1989) to recover a companion metaphor that has been largely forgotten in the “mainstreaming” of intersectionality in (white-dominated) feminist theory. In addition to the now-famous intersection metaphor, Crenshaw offers the basement metaphor to show how—by privileging monistic, mutually exclusive, and analogically constituted categories of “race” and “sex” tethered, respectively, to masculinity and whiteness—antidiscrimination law functions to reproduce social hierarchy, rather than to remedy it, denying (...) Black women plaintiffs legal redress. I argue that in leaving the basement behind, deployments of “intersectionality” that deracinate the concept from its origins in Black feminist thought also occlude Crenshaw's account of the socio-legal reproduction of hierarchical power.

Among the myriad longstanding political, socioeconomic, and moral debates focused on the fair distribution of health-care resources within the United States, those addressing intergenerational justice tend to produce the most heat and, often, the least amount of light. The familiar narratives tend to be binary ones of opposing generational stakeholders. While a great number of proposed solutions focus on reconfiguring rationing priorities, this paper will instead shift the discourse to intergenerational interdependence, suggesting that these conflict-born moral dilemmas are in important (...) ways false. The alternative view of intergenerational relations defended here is grounded in an interdependent, rather an oppositional, model of human relationships. I argue that this interdependence can best be realized through a deliberate movement toward intergenerational narrative understandings, as well as through physical proximities. I conclude by considering several ongoing intergenerational projects directed at just such a goal. (shrink)

Human and automated tutors attempt to choose pedagogical activities that will maximize student learning, informed by their estimates of the student's current knowledge. There has been substantial research on tracking and modeling student learning, but significantly less attention on how to plan teaching actions and how the assumed student model impacts the resulting plans. We frame the problem of optimally selecting teaching actions using a decision-theoretic approach and show how to formulate teaching as a partially observable Markov decision process planning (...) problem. This framework makes it possible to explore how different assumptions about student learning and behavior should affect the selection of teaching actions. We consider how to apply this framework to concept learning problems, and we present approximate methods for finding optimal teaching actions, given the large state and action spaces that arise in teaching. Through simulations and behavioral experiments, we explore the consequences of choosing teacher actions under different assumed student models. In two concept-learning tasks, we show that this technique can accelerate learning relative to baseline performance. (shrink)

The ability to be creative is often considered a unique characteristic of conscious beings and many efforts have been directed at demonstrating a relationship between creativity and the personality construct of psychoticism. The present study sought to investigate this link explicitly by focusing on discrete facets of creative cognition, namely the originality/novelty dimension and the practicality/usefulness dimension. Based on Eysenck’s conceptualisation of psychoticism as being characterised by an overinclusive cognitive style, it was expected that higher levels of psychoticism would accompany (...) a greater degree of conceptual expansion and elevated levels of originality in creative imagery, but would be unrelated to the practicality/usefulness of an idea. These hypotheses were confirmed in 80 healthy participants who were contrasted based on their EPQ psychoticism scale scores. Our findings suggest that the link between psychoticism and creativity is based on associative thinking and broader but weak top-down activation patterns rather than on goal-related thinking.

Watching another person take actions to complete a goal and making inferences about that person's knowledge is a relatively natural task for people. This ability can be especially important in educational settings, where the inferences can be used for assessment, diagnosing misconceptions, and providing informative feedback. In this paper, we develop a general framework for automatically making such inferences based on observed actions; this framework is particularly relevant for inferring student knowledge in educational games and other interactive virtual environments. Our (...) approach relies on modeling action planning: We formalize the problem as a Markov decision process in which one must choose what actions to take to complete a goal, where choices will be dependent on one's beliefs about how actions affect the environment. We use a variation of inverse reinforcement learning to infer these beliefs. Through two lab experiments, we show that this model can recover people's beliefs in a simple environment, with accuracy comparable to that of human observers. We then demonstrate that the model can be used to provide real-time feedback and to model data from an existing educational game. (shrink)

Wittgenstein likens philosophy both to an illness and to a therapy. The reflections he dedicates to mental disturbance in On Certainty shed some light on this ambivalence, by pointing at the intertwined themes of common sense, doubt, mistake, reasonableness, and normality. Wittgenstein’s remarks have sometimes been compared to the description of the symptoms of what psychopathologists have called the loss of natural self-evidence, or the loss of common sense. Besides briefly recalling some of the outcomes of this debate in literature, (...) I focus on Wittgenstein’s conception of “hinges”, the basic practical certainties which patients suffering from the loss of common sense seem to lack. By working on this comparison, I offer an interpretation of Wittgenstein’s idea of philosophy that clarifies both its insane and its therapeutic side. (shrink)
