The current debate over systematicity concerns the formal conditions a scheme of mental representation must satisfy in order to explain the systematicity of thought.1 The systematicity of thought is assumed to be a pervasive property of minds, and can be characterized (roughly) as follows: anyone who can think T can think systematic variants of T, where the systematic variants of T are found by permuting T’s constituents. So, for example, it is an alleged fact that anyone who can think the (...) thought that John loves Mary can think the thought that Mary loves John, where the latter thought is a systematic variant of the former.

Diversity is an undeniable fact of nature, and there is now evidence that nature did not stop generating diversity just before “designing” the human brain :15,468–15,473. https://doi.org/10.1073/pnas.1509654112, 2015). If neurodiversity is a fact of nature, what about neurodivergence? Although the terms “neurodiversity” and “neurodivergence” are sometimes used interchangeably, this is, we believe, a mistake: “neurodiversity” is a term of inclusion whereas “neurodivergence” is a term of exclusion. To make the difference clear, note that everyone can be said to be neurodiverse, (...) but that it is almost impossible for everyone to be neurodivergent. Neurodivergence is, we claim here, a fact of society. Neurodivergent individuals are those whose cognitive profile diverges from an established cognitive norm, a norm that is not an objective statistical fact of human neurological functioning but a standard established and maintained by socio-political processes. In this paper, we describe the socio-political mechanisms that build neurodivergence out of neurodiversity which, inspired by Mihai :395–416. https://doi.org/10.1057/s41296-017-0186-z, 2018), we call “epistemic and cognitive marginalization”. First, we extend the traditional concept of neurodiversity, which we believe too closely tied to a neuroreductionist conception of cognition, to that of “extended neurodiversity,” thereby viewing neurodiversity through the lens of 4E cognition. Considering that human cognition depends on epistemic resources, both for their construction and their online dynamic expression, we hypothesize that the differential access to epistemic resources in society, a form of epistemic injustice, is an overlooked mechanism that turns neurodiversity into neurodivergence. In doing so, we shed light on a type of epistemic injustice that might be missing from the epistemic injustice literature: cognitive injustices. (shrink)

While COVID-19 spreads aggressively and rapidly across the globe, many societies have also witnessed the spread of other viral phenomena like misinformation, conspiracy theories, and general mass suspicions about what is really going on. This study investigates how exposure to and trust in information sources, and anxiety and depression, are associated with conspiracy and misinformation beliefs in eight countries/regions during the COVID-19 pandemic. Data were collected in an online survey fielded from May 29, 2020 to June 12, 2020, resulting in (...) a multinational representative sample of 8,806 adult respondents. Results indicate that greater exposure to traditional media is associated with lower conspiracy and misinformation beliefs, while exposure to politicians and digital media and personal contacts are associated with greater conspiracy and misinformation beliefs. Exposure to health experts is associated with lower conspiracy beliefs only. Higher feelings of depression are also associated with greater conspiracy and misinformation beliefs. We also found relevant group- and country differences. We discuss the implications of these results. (shrink)

Ensuring that life-saving antimicrobials remain available as effective treatment options in the face of rapidly rising levels of antimicrobial resistance will require a massive and coordinated global effort. Setting a collective direction for progress is the first step towards aligning global efforts on AMR. This process would be greatly accelerated by adopting a unifying global target — a well-defined global target that unites all countries and sectors. The proposed pandemic instrument — with its focus on prevention, preparedness and response — (...) represents an ideal opportunity to develop and adopt a unifying global target that catalyzes global action on AMR. We propose three key characteristics of a unifying global target for AMR that — if embedded within the pandemic preparedness instrument — could rally public support, funding, and political commitment commensurate with the scale of the AMR challenge.

Advances in artificial intelligence, as well as its increased presence in everyday life, have brought the emergence of many new phenomena, including an intriguing appearance of what seems to be a variant of body dysmorphic disorder, coined “Snapchat dysmorphia”. Body dysmorphic disorder is a DSM-5 psychiatric disorder defined as a preoccupation with one or more perceived defects or flaws in physical appearance that are not observable or appear slight to others. Snapchat dysmorphia is fueled by automated selfie filters that reflect (...) unrealistic sociocultural standard. In this paper, we discuss how body dysmorphic disorder and related body image distortions could arise, using the conceptual resources provided by the active inference framework. We suggest that these disorders involve dysfunctional self-modelling which entails maladaptive internalization of sociocultural preferences during adolescent identity formation. Identity formation is hereby described as cycles of interpersonal active inference that arbitrate between identity exploration and commitment. We propose that impaired self-modelling is unable to reduce interpersonal uncertainty during identity exploration, which, over time, degenerates into uncontrollable epistemic habits that isolate the body image from corrective sensory evidence. In light of these insights, we subsequently explore some of the consequences of image-centered social media platforms on the identity formation process. We conclude that heightened interpersonal uncertainty in this novel context could precipitate the onset of body dysmorphic disorder and related body image distortions, particularly when selfie filters are involved.

Background The prioritization protocols for accessing adult critical care in the extreme pandemic context contain tiebreaker criteria to facilitate decision-making in the allocation of resources between patients with a similar survival prognosis. Besides being controversial, little is known about the public acceptability of these tiebreakers. In order to better understand the public opinion, Quebec and Ontario’s protocols were presented to the public in a democratic deliberation during the summer of 2022. Objectives (1) To explore the perspectives of Quebec and Ontario (...) citizens regarding tiebreakers, identifying the most acceptable ones and their underlying values. (2) To analyze these results considering other public consultations held during the pandemic on these criteria. Methods This was an exploratory qualitative study. The design involved an online democratic deliberation that took place over two days, simultaneously in Quebec and Ontario. Public participants were selected from a community sample which excluded healthcare workers. Participants were first presented the essential components of prioritization protocols and their related issues (training session day 1). They subsequently deliberated on the acceptability of these criteria (deliberation session day 2). The deliberation was then subject to thematic analysis. Results A total of 47 participants from the provinces of Quebec (n = 20) and Ontario (n = 27) took part in the online deliberation. A diverse audience participated excluding members of the healthcare workforce. Four themes were identified: (1) Priority to young patients - the life cycle - a preferred tiebreaker; (2) Randomization - a tiebreaker of last resort; (3) Multiplier effect of most exposed healthcare workers - a median acceptability tiebreaker, and (4) Social value – a less acceptable tiebreaker. Conclusion Life cycle was the preferred tiebreaker as this criterion respects intergenerational equity, which was considered relevant when allocating scarce resources to adult patients in a context of extreme pandemic. Priority to young patients is in line with other consultations conducted around the world. Additional studies are needed to further investigate the public acceptability of tiebreaker criteria.

The genetically manipulated organism crisis demonstrated that technological development based solely on the law of the marketplace and State protection against serious risks to health and safety is no longer a warrant of ethical acceptability. In the first part of our paper, we critique the implicitly individualist social-acceptance model for State regulation of technology and recommend an interdisciplinary approach for comprehensive analysis of the impacts and ethical acceptability of technologies. In the second part, we present a framework for the analysis (...) of impacts and acceptability, devised—with the goal of supporting the development of specific nanotechnological applications—by a team of researchers from various disciplines. At the conceptual level, this analytic framework is intended to make explicit those various operations required in preparing a judgement about the acceptability of technologies that have been implicit in the classical analysis of toxicological risk. On a practical level, we present a reflective tool that makes it possible to take into account all the dimensions involved and understand the reasons invoked in determining impacts, assessing them, and arriving at a judgement about acceptability.

As part of a (bio)colonial project, the biological information of Indigenous Peoples has historically been under scientific scrutiny, with very limited benefits for communities and donors. Negative past experiences have contributed to further exclude Indigenous communities from novel developments in the field of omics research. Over the past decade, new guidelines, reflections, and projects of genetic research with Indigenous Peoples have flourished in Australia, providing opportunities to move the field into a place of respect and ethical relationships. This review explores (...) the ethical and cultural implications of the use of biological samples from Indigenous communities in biomedical research. A structured framework outlining emerging topics of interest for the development of respectful omics research partnerships with Indigenous Australians is presented. This paper highlights aspects related to Indigenous governance, community and individual consent, respectful handling of biological samples, data management, and communication in order to protect Indigenous interests and rights and to promote communities’ autonomy.

In this paper, we describe how critical data designers have created projects that ‘push back’ against the eclipse of environmental problems by dominant orders: the pioneering pollution database Scorecard, released by the US NGO Environmental Defense Fund in 1997; the US Environmental Protection Agency’s EnviroAtlas that brings together numerous data sets and provides tools for valuing ecosystem services; and the Houston Clean Air Network’s maps of real-time ozone levels in Houston. Drawing on ethnographic observations and interviews, we analyse how critical (...) data designers turn scientific data and findings into claims and visualisations that are meaningful in contemporary political terms. The skills of critical data designers cross scales and domains; they must identify problems calling for public consideration, and then locate, access, link, and create visualisations of data relevant to the problem. We conclude by describing hazards ahead in work to leverage Big Data to understand and address environmental problems. Critical data designers need to understand what counts as a societal problem in a particular context, what doesn’t, what is seen as connected and not, what is seen as ethically charged, and what is exonerated and discounted. Such recognition is produced through interpretive, ‘close reading’ of the historical moment in which they operate. (shrink)

BackgroundIn the Canadian Alliance for Healthy Hearts and Minds (CAHHM) cohort, participants underwent magnetic resonance imaging (MRI) of the brain, heart, and abdomen, that generated incidental findings (IFs). The approach to managing these unexpected results remain a complex issue. Our objectives were to describe the CAHHM policy for the management of IFs, to understand the impact of disclosing IFs to healthy research participants, and to reflect on the ethical obligations of researchers in future MRI studies.MethodsBetween 2013 and 2019, 8252 participants (...) (mean age 58 ± 9 years, 54% women) were recruited with a follow-up questionnaire administered to 909 participants (40% response rate) at 1-year. The CAHHM policy followed a restricted approach, whereby routine feedback on IFs was not provided. Only IFs of severe structural abnormalities were reported.ResultsSevere structural abnormalities occurred in 8.3% (95% confidence interval 7.7–8.9%) of participants, with the highest proportions found in the brain (4.2%) and abdomen (3.1%). The majority of participants (97%) informed of an IF reported no change in quality of life, with 3% of participants reporting that the knowledge of an IF negatively impacted their quality of life. Furthermore, 50% reported increased stress in learning about an IF, and in 95%, the discovery of an IF did not adversely impact his/her life insurance policy. Most participants (90%) would enrol in the study again and perceived the MRI scan to be beneficial, regardless of whether they were informed of IFs. While the implications of a restricted approach to IF management was perceived to be mostly positive, a degree of diagnostic misconception was present amongst participants, indicating the importance of a more thorough consent process to support participant autonomy.ConclusionThe management of IFs from research MRI scans remain a challenging issue, as participants may experience stress and a reduced quality of life when IFs are disclosed. The restricted approach to IF management in CAHHM demonstrated a fair fulfillment of the overarching ethical principles of respect for autonomy, concern for wellbeing, and justice. The approach outlined in the CAHHM policy may serve as a framework for future research studies.Clinical trial registrationhttps://clinicaltrials.gov/ct2/show/nct02220582. (shrink)

A recently proposed approach to relativistic quantum mechanics is applied to the problem of a particle in a quadratic potential. The methods, both exact and approximate, allow one to obtain eigenstate energy levels and wavefunctions, using conventional numerical eigensolvers applied to Schrödinger-like equations. Results are obtained over a nine-order-of-magnitude variation of system parameters, ranging from the non-relativistic to the ultrarelativistic limits. Various trends are analyzed and discussed—some of which might have been easily predicted, others which may be a bit more (...) surprising. (shrink)

A viable evolutionary cognitive psychology requires that specific cognitive capacities be (a) heritable and (b) ‘quasi-independent’ from other heritable traits. They must be heritable because there can be no selection for traits that are not. They must be quasi-independent from other heritable traits, since adaptive variations in a specific cognitive capacity could have no distinctive consequences for fitness if effecting those variations required widespread changes in other unrelated traits and capacities as well. These requirements would be satisfied by innate cognitive (...) modules, as the dominant paradigm in evolutionary cognitive psychology assumes. However, those requirements would also be satisfied by heritable learning biases, perhaps in the form of architec- tural or chronotopic constraints, that operated to increase the canalization of specific cognitive capacities in the ancestral environment (Cummins and Cummins 1999). As an organism develops, cognitive capacities that are highly canalized as the result of heritable learning biases might result in an organism that is behaviourally quite similar to an organism whose innate modules come on line as the result of various environ- mental triggers. Taking this possibility seriously is increasingly important as the case against innate cognitive modules becomes increasingly strong. (shrink)

In a recently published paper, we argued that theories of cultural evolution can gain explanatory power by being more pluralistic. In his reply to it, Dennett agreed that more pluralism is needed. Our paper’s main point was to urge cultural evolutionists to get their hands dirty by describing the fine details of cultural products and by striving to offer detailed and, when explanatory, varied algorithms or mechanisms to account for them. While Dennett’s latest work on cultural evolution does marvelously well (...) on the first point, it has only whet our appetite on the second. Accordingly, the present paper aims to show what an evolutionary explanation of culture that takes the variety of cultural evolution mechanisms seriously would look like. We will focus on the cultural evolution of social epistemic mechanisms and we will propose that Darwinian algorithms should be complemented with a cultural analogue of the error reduction mechanism proposed to account for human cognition, with a particular emphasis on the necessity to build independencies between different sub-systems in charge of tracking states of the world. To illustrate our point, we will present how the evolution of the legal system as epistemic systems can be understood as a process of building increasingly better independencies and how various criticisms of the actual legal system calls for building even more of them.

In developmental lexical–gustatory synesthesia, specific words can trigger taste perceptions and these synesthetic associations are generally stable. We describe a case of multilingual lexical–gustatory synesthesia for whom some synesthesias were bidirectional as some tastes also triggered auditory word associations. Evoked concurrents could be gustatory but also tactile sensations. In addition to words and pseudowords, many voices were effective inducers, suggesting increased connections between cortical taste areas and both voice-selective and language-selective areas. Lasting changes in some evoked tastes occurred during childhood (...) suggesting that some plasticity can be present after the initial learning of associations. Inducers were often linked to taste concurrents phonologically or semantically, but also through identifiable childhood episodes . Several inducers were phonologically linked to episodic inducers suggesting a process of secondary acquisition for many inducers. Implications of these observations are discussed. (shrink)

Tout : vague et imposant petit mot. Présent à tout bout de champ, dans tant d'expressions, de toute éternité et en toute modestie. Ce mot-là, ce n'est pas rien. Les articles qui suivent explorent les rapports de tout et de rien, et les valeurs que prend le tout à différentes époques : comment il est représenté – personnifié? – et comment il est présupposé dans la démarche même d'écriture. Car l'ambition de la littérature est peut-être bien de dire tout : (...) dire la totalité du monde, d'une société, d'une époque, dire le rapport – forcément spirituel? – au tout qui ne se laisse saisir, tout dire de soi, ou encore utiliser tous les mots du dictionnaire.

The medical record, as a managerial, historic, and legal document, serves many purposes. Although its form may be well established and many of the cases documented in it routine in medical experience, what is written in the medical record nevertheless records decisions and actions of individuals. Viewed as an interpretive text, it can itself become the object of interpretation. This essay applies literary theory and methodology to the structure, content, and writing style(s) of an actual medical record for the purpose (...) of exploring the relationship between the forms and language of medical discourse and the daily decisions surrounding medical treatment. The medical record is shown to document not only the absence of a consistent treatment plan for the patient studied but also a breakdown in communication between different health professionals caring for that patient. The paper raises questions about the kind of education being given to house staff in this instance. The essay concludes with a consideration of how such situations might be more generally avoided.

RésuméLa sémiotique a inventé ou utilisé plusieurs modèles logiques pour représenter la structure élémentaire de la signification. Le carré sémiotique est sans doute l’un des plus célèbres de ces modèles. Il faut se demander, devant l’importance des phénomènes triadiques, si les modèles dyadiques sont (toujours) adaptés à leur description ou s’il ne faudrait pas se tourner (aussi) vers des modèles triadiques. Or, les modèles triadiques de la structure élémentaire de la signification nous apparaissent bien moins nombreux. À notre connaissance, seule (...) la sémiotique de Peirce et le templum de Boudon occupent cet espace autrement laissé vacant. Nous voulons ici à la fois présenter et exemplifier le templum et le compléter, en nous inspirant du carré sémiotique, pour le faire évoluer vers un « prisme sémiotique ». Nous proposerons également d’autres modèles logiques, comme le pentalemme et le cube sémiotiques. Au passage, nous étudierons plusieurs questions et problèmes – dont la décidabilité – entourant les modèles logiques. Nous ferons quelques applications sommaires de certains modèles, sur le temps, l’espace et la transcendance principalement. (shrink)

As is often the case when scientific or engineering fields emerge, new concepts are forged or old ones are adapted. When this happens, various arguments rage over what ultimately turns out to be conceptual misunderstandings. At that critical time, there is a need for an explicit reflection on the meaning of the concepts that define the field. In this position paper, we aim to provide a reasoned framework in which to think about various issues in the field of distributed cognition. (...) We argue that both relevant concepts, distribution and cognition, must be understood as continuous. As it is used in the context of distributed cognition, the concept of distribution is essentially fuzzy, and we will link it to the notion of emergence of system-level properties. The concept of cognition must also be seen as fuzzy, but for a different reason: due to its origin as an anthropocentric concept, no one has a clear handle on its meaning in a distributed setting. As the proposed framework forms a space, we then explore its geography and visit famous landmarks. (shrink)

In our critical review of Doing without Concepts, we argue that although the heterogeneity hypothesis (according to which exemplars, prototypes and theories are natural kinds that should replace ‘concept’) may end fruitless debates in the psychology of concepts, Edouard Machery did not anticipate one consequence of his suggestion: Definitions now acquire a new status as another one of the bodies of information replacing ‘concept’. In order to support our hypothesis, we invoke dual-process models to suggest that prototypes, exemplars and theories (...) are ‘Type 1’ concepts (automatic, implicit) and definitions ‘Type 2’ concepts (controlled, explicit). In the context of this argument, we suggest that one must better distinguish between Type 1 theories (e.g., Bayesian causal nets) and Type 2 theories (e.g., scientific) that explicitly control definitions.

Cet ouvrage est né d'une réalité et d'un besoin. La petite Maëlle, enfant autiste, est devenue adolescente, alors il fallait la suivre pour mieux l'accompagner dans cette nouvelle étape de sa vie. Comme cela arrive chez les autres enfants qui entrent dans l'adolescence, tout est remis en question : les idéaux, l'identité, l'amitié, l'amour. Entre-temps, il y a eu la publication de la cinquième version du Manuel diagnostique et statistique des troubles mentaux (DSM-5). Il fallait donc étudier cette entrée dans (...) l'adolescence à partir des données diagnostiques les plus récentes. Autisme et adolescence est la suite de L'autisme, un jour à la fois et d'Accompagner un enfant autiste. Encore ici, la mère Catherine Kozminski et la psychologue Nathalie Poirier entrent en dialogue afin de se mettre à l'écoute des besoins de l'adolescente et d'élaborer les meilleures formes d'accompagnement. Il en résulte un ouvrage plein de sensibilité et rempli de solutions pratiques. (shrink)

Ce texte revient sur le parcours intellectuel de Castoriadis pour réfléchir le lien entre sa situation d'exilé en France et sa pensée philosophique. Sans parler de rapport intrinsèque entre l'existence et la pensée, on peut toutefois entendre certaines résonances entre un parcours de vie marqué par l'exil et un cheminement intellectuel travaillé par le mise en question des concepts philosophiques traditionnels. Ainsi la réflexion menée par Castoriadis, à travers sa critique de l'ontologie déterministe et identitaire, permet d'articuler autrement le rapport (...) entre désordre et institution. Ne pouvant se prévaloir d'aucune autorité sous-jacente, la politique démocratique doit dès lors se composer en vertu de la créativité dont peuvent faire preuve les individus et les sociétés.

Many accounts of scientific modelling assume that models can be decomposed into the contributions made by their accurate and inaccurate parts. These accounts then argue that the inaccurate parts of the model can be justified by distorting only what is irrelevant. In this paper, I argue that this decompositional strategy requires three assumptions that are not typically met by our best scientific models. In response, I propose an alternative view in which idealized models are characterized as holistically distorted representations that (...) are justified by allowing for the application of various modelling techniques.
