We routinely observe others’ choices and use them to guide our own. Whose choices influence us more, and why? Prior work has focused on the effect of perceived similarity between two individuals, such as the degree of overlap in past choices or explicitly recognizable group affiliations. In the real world, however, any dyadic relationship is part of a more complex social structure involving multiple social groups that are not directly observable. Here we suggest that human learners go beyond dyadic similarities (...) in choice behaviors or explicit group memberships; they infer the structure of social influence by grouping individuals based on choices, and they use these groups to decide whose choices to follow. We propose a computational model that formalizes this idea, and we test the model predictions in a series of behavioral experiments. In Experiment 1, we reproduce a well-established finding that people's choices are more likely to be influenced by someone whose past choices are more similar to their own past choices, as predicted by our model as well as dyadic similarity models. In Experiments 2–5, we test a set of unique predictions of our model by looking at cases where the degree of choice overlap between individuals is equated, but their choices indicate a latent group structure. We then apply our model to prior empirical results on infants’ understanding of others’ preferences, presenting an alternative account of developmental changes. Finally, we discuss how our model relates to classical findings in the social influence literature and the theoretical implications of our model. Taken together, our findings demonstrate that structure learning is a powerful framework for explaining the influence of social information on decision making in a variety of contexts. (shrink)

Flexibility is one of the hallmarks of human problem‐solving. In everyday life, people adapt to changes in common tasks with little to no additional training. Much of the existing work on flexibility in human problem‐solving has focused on how people adapt to tasks in new domains by drawing on solutions from previously learned domains. In real‐world tasks, however, humans must generalize across a wide range of within‐domain variation. In this work we argue that representational abstraction plays an important role in (...) such within‐domain generalization. We then explore the nature of this representational abstraction in realistically complex tasks like video games by demonstrating how the same model‐based planning framework produces distinct generalization behaviors under different classes of task representation. Finally, we compare the behavior of agents with these task representations to humans in a series of novel grid‐based video game tasks. Our results provide evidence for the claim that within‐domain flexibility in humans derives from task representations composed of propositional rules written in terms of objects and relational categories.

Our objective is to test an optimality model of human fertility that specifies the behavioral requirements for fitness maximization in order (a) to determine whether current behavior does maximize fitness and, if not, (b) to use the specific nature of the behavioral deviations from fitness maximization towards the development of models of evolved proximate mechanisms that may have maximized fitness in the past but lead to deviations under present conditions. To test the model we use data from a representative sample (...) of 7,107 men living in Albuquerque, New Mexico, between 1990 and 1993. The model we test proposes that low fertility in modern settings maximizes number of grandchildren as a result of a trade-off between parental fertility and next generation fertility. Results do not show the optimization, although the data do reveal a trade-off between parental fertility and offspring education and income.We propose that two characteristics of modern economies have led to a period of sustained fertility reduction and to a corresponding lack of association between income and fertility. The first is the direct link between costs of investment and wage rates due to the forces of supply and demand for labor in competitive economies. The second is the increasing emphasis on cumulative knowledge, skills, and technologies in the production of resources. Together they produce historically novel conditions. These two features of modern economies may interact with evolved psychological and physiological mechanisms governing fertility and parental investment to produce behavior that maximizes the economic productivity of lineages at the expense of fitness. If cognitive processes evolved to track diminishing returns to parental investment and if physiological processes evolved to regulate fertility in response to nutritional state and patterns of breast feeding, we might expect non-adaptive responses when returns from parental investment do not diminish until extremely high levels are reached. With high economic payoffs from parental investment, people have begun to exercise cognitive regulation of fertility through contraception and family planning practices. Those cognitive processes maynot have evolved to handle fitness trade-offs between fertility and parental investment. (shrink)

Issues of reliability are claiming center-stage in the epistemology of machine learning. This paper unifies different branches in the literature and points to promising research directions, whilst also providing an accessible introduction to key concepts in statistics and machine learning – as far as they are concerned with reliability.

Big Ideas for Little Kids includes everything a teacher, a parent, or a college student needs to teach philosophy to elementary school children from picture books. Written in a clear and accessible style, the book explains why it is important to allow young children access to philosophy during primary-school education. Wartenberg also gives advice on how to construct a "learner-centered" classroom, in which children discuss philosophical issues with one another as they respond to open-ended questions by saying whether they agree (...) or disagree with what others have said.

Cette étude essaye d’établir qu’il y a deux notions très différentes de « fondation » à l’œuvre dans les Recherches logiques de Husserl. Dans la IIIème Recherche, où le terme est formellement introduit, lorsqu’il se demande quels sont les contenus qui peuvent exister d’une manière autonome (indépendants) et lesquels peuvent exister uniquement en tant que moments d’autre chose (dépendants), Husserl suit ce que j’appelle un « modèle ontologique ». Selon ce modèle, le concret possède une priorité sur à l’abstrait qui (...) est fondé en lui. Dans la VIème Recherche, en revanche, Husserl s’oriente principalement sur un « modèle gnoséologique » qui voit le complexe comme fondé sur ce qui est relativement simple, étant donné que les expériences d’ordre supérieur (telles les perceptions de types d’objets plus complexes) sont « fondées sur » des expériences plus simples, bien qu’elles ne puissent pas y être réduites. L’exemple principal ici est celui des intuitions catégoriales : fondées sur les intuitions sensibles, elles n’y sont pas réductibles. Mais cette distinction entre deux sens différents du terme de « fondation » peut également nous aider à mieux comprendre de nombreuses thèses husserliennes plutôt controversées. Par exemple, elle peut nous permettre de mieux comprendre dans quelle mesure faire l’expérience d’un être humain comme un tout se fonde sur l’expérience d’un corps physique, et cela même si l’étant que nous rencontrons inclut à la fois des aspects corporels et des aspects spirituels – les deux étant vus, d’une manière essentielle, comme des moments de cette unique personne qui fait l’objet de notre expérience.

This paper lays the groundwork for a theory of time allocation across the life course, based on the idea that strength and skill vary as a function of age, and that return rates for different activities vary as a function of the combination of strength and skills involved in performing those tasks. We apply the model to traditional human subsistence patterns. The model predicts that young children engage most heavily in low-strength/low-skill activities, middle-aged adults in high-strength/high-skill activities, and older adults (...) in low-strength/high-skill activities. Tests among Machiguenga and Piro forager-horticulturalists of southeastern Peru show that males and females focus on low-strength/low-skill tasks early in life (domestic tasks and several forms of fishing), switch to higher-strength/higher-skill activities in their twenties and thirties (hunting, fishing, and gardening for males; fishing and gardening for females), and shift focus to high-skill activities late in life (manufacture/repair, food processing).

FOSTER J, CHIANG F, HILLARD RC, HALL P and HEATH A. Nursing Inquiry 2010; 17: 309–316 Team process in community‐based participatory research on maternity care in the Dominican RepublicA cross‐cultural team consisting of US trained academic midwife researchers, Dominican nurses, and Dominican community leaders have partnered in this international nursing and midwifery community‐based participatory research (CBPR) project in the Dominican Republic to understand the community experience with publicly funded maternity services. The purpose of the study was to understand community (...) perceptions of maternity services. This article highlights the activities that the research team carried out during each phase of the research process, and how they established team identity, team trust, and team efficacy. This research has created a platform for new avenues for health providers and community to partner to improve maternal‐newborn care. Community‐based participatory research is one way forward to address the past and present inequities constitutive of global health disparities. (shrink)

In this book, T. M. Scanlon offers new answers to these questions, as they apply to the central part of morality that concerns what we owe to each other.

Thomas Reid , the Scottish natural and moral philosopher, was one of the founding members of the Aberdeen Philosophical Society and a significant figure in the Scottish Enlightenment. Reid believed that common sense should form the foundation of all philosophical inquiry. He criticised the sceptical philosophy propagated by his fellow Scot David Hume and the Anglo-Irish bishop George Berkeley, who asserted that the external world did not exist outside the human mind. Reid was also critical of the theory of (...) ideas propagated by Locke and Descartes, arguing that it was incompatible with physical and experiential facts. For Reid, our senses demonstrate that the external world must exist, and this work is organised in chapters examining each of the senses in turn. The book, based on his lectures, was first published in 1764 when Reid was a regent professor at King's College, Aberdeen, and was reissued in 1818. (shrink)

This paper is an exposition and evaluation of the Agustín Rayo's views about the epistemology and metaphysics of mathematics, as they are presented in his book The Construction of Logical Space.

In recent years an increasing number of psychologists have begun to explore the prevalence, causes and effects of ordinary people’s intuitions about moral realism. Many of these studies have lacked in construct validity, i.e., they have failed to measure moral realism. My aim in this paper accordingly is to motivate and guide methodological improvements. In analysis of prominent existing measures, I develop general recommendations for overcoming ten prima facie serious worries about research on folk moral realism. G1 and G2 require (...) studies’ answer choices to be as metaethically comprehensive as methodologically feasible. G3 and G4 prevent fallacious inferences from intuitions about related debates. G5 and G6 limit first-order moral and epistemic influences. G7 address studies’ instructions. And G8 and G9 suggest tests of important psychological presuppositions. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Things Are NOT OkayLynne HillardThree doctors, each with good intentions, led us to believe that everything would be all right for our son Ben. In the fall of 2008, Ben presented with two documented seizures. We first saw a doctor from our pediatrician’s office. He told us not to worry since the basic neurological physical exam showed nothing, but recommended that we see a pediatric neurologist. He gave us (...) a list of recommended doctors, and upon leaving the examining room the doctor then said, “Don’t worry. It’s not a brain tumor.”We arranged a meeting with one of the pediatric neurologists who had been practicing for a long time and had worked in one of the well–respected children’s hospitals before going into private practice. She was attentive and kind and spent a couple hours with us as we went over Ben’s medical history. She examined Ben and found nothing unusual, in fact per her notes, “his neurological examination is better than normal.” She said that she would order an EEG and a brain MRI because he had two witnessed seizures. She asked us to look into family history to see if there was anyone with a history of seizures in either one of our families. Upon leaving she said not to worry that it was probably something that he would out grow.After looking into family history, I found out that my older brother had had a couple of seizures when he was about twelve. He was put on phenobarbital. He eventually outgrew the seizures. Armed with this information I felt certain that Ben’s issues were hereditary. It was right before Christmas 2008, so I delayed on getting the EEG and brain MRI until January of that new year. The results of the EEG were unremarkable. The following week was the MRI. The day after the MRI, the receptionist at the neurologist’s office called. She requested that we come in the next day and asked that Ben not come to the appointment.“I am sorry to tell you, but Ben has a brain tumor.” What? I couldn’t even concentrate on what the doctor was saying. Ben’s tumor was located in the right temporal lobe and extensively involved the right amygdala and right hippocampus.I remember feeling completely overwhelmed with the process of choosing the individual who would ultimately perform brain surgery on our son. My husband and I interviewed three surgeons within a few weeks. On March 20 of 2009 Ben underwent surgery. The neurosurgeon was able to remove about 75 percent of the tumor. Two days after surgery Ben was released from the hospital. I remember that surreal feeling. My son had just had brain surgery and now we were going home with a list of medications and a schedule for administering the medications. I felt inept, unprepared, and yet relieved that my son had made it through; he could talk, he could move all his limbs and everything appeared to be normal. The only distinguishing feature that anything had happened was the six–inch scare on the side of his head.The pathology report said it was a DNET tumor (Dysembryoplastic Neuroepithelial Tumor), one that should not re–grow or cause any further problems. I remember the audible sigh of relief that came out of my mouth. I remember the neurosurgeon’s words: “Ben will grow up to be a fi ne young man, and you will dance with him at his wedding.” I wanted to be happy, like I had won the lottery, but I had this feeling that there must be something more to this, it couldn’t be this easy.In his second year at preschool Ben’s behavior problems became more obvious. When Ben became overwhelmed he would just sit down and not budge. Even when the director of the preschool asked us if there were any problems that were the result of his anti–seizure medication or his surgery, we said “no” because we were told “all should be good.” But all along there was that nagging feeling that not all was good in Ben’s world.

It will be noticed that, in the stemma above, no line of descent is marked from the first generation registered therein to the following generations. The genealogy of the Emperor Nerva is customarily traced back to the consul of 36 b.c., M. Cocceius Nerva. This short note will underline the ancient testimony found amongst the Pseudacroniana tracing his descent from the latter's brother, the consummate diplomat. There are ramifications. Amongst the items of interest will be the light shone upon what (...) Dio and Eutropius understood to be Nerva's standing at the time of his accession. Before passing on to Pseudacron's datum, it might be worthwhile pausing on that point, as well as briefly contemplating the factors that actually bore upon the emperor's ancestral training. (shrink)

In recent years, a plethora of high-profile scientific publications has been reporting about machine learning algorithms outperforming clinicians in medical diagnosis or treatment recommendations. This has spiked interest in deploying relevant algorithms with the aim of enhancing decision-making in healthcare. In this paper, we argue that instead of straightforwardly enhancing the decision-making capabilities of clinicians and healthcare institutions, deploying machines learning algorithms entails trade-offs at the epistemic and the normative level. Whereas involving machine learning might improve the accuracy of medical (...) diagnosis, it comes at the expense of opacity when trying to assess the reliability of given diagnosis. Drawing on literature in social epistemology and moral responsibility, we argue that the uncertainty in question potentially undermines the epistemic authority of clinicians. Furthermore, we elucidate potential pitfalls of involving machine learning in healthcare with respect to paternalism, moral responsibility and fairness. At last, we discuss how the deployment of machine learning algorithms might shift the evidentiary norms of medical diagnosis. In this regard, we hope to lay the grounds for further ethical reflection of the opportunities and pitfalls of machine learning for enhancing decision-making in healthcare. (shrink)

Thomas Reid is now recognized as one of the towering figures of the Enlightenment. Best known for his published writings on epistemology and moral theory, he was also an accomplished mathematician and natural philosopher, as an earlier volume of his manuscripts edited by Paul Wood for the Edinburgh Reid Edition, Thomas Reid on the Animate Creation, has shown. The Correspondence of Thomas Reid collects all of the known letters to and from Reid in a fully annotated form. (...) Letters already published by Sir William Hamilton and others have been reedited, and roughly half of the letters included appear in print for the first time. Writing in 1802, Reid's disciple and biographer Dugald Stewart doubted that Reid's correspondence &"would be generally interesting.&" This collection proves otherwise, for the letters illuminate virtually every aspect of Reid's life and career and, in some instances, provide us with invaluable evidence about activities otherwise undocumented in his manuscripts or published works. Through his correspondence we can trace Reid's relations with contemporaries such as David Hume and his colleagues at both King's College, Aberdeen, and the University of Glasgow, as well as his engagement with the most controversial philosophical, scientific, and political issues of his day. If anything, the letters assembled here serve as the starting point for understanding Reid and his place in the Enlightenment. (shrink)

Conciliatory theories of disagreement require that one lower one’s confidence in a belief in the face of disagreement from an epistemic peer. One question about which people might disagree is who should qualify as an epistemic peer and who should not. But when putative epistemic peers disagree about epistemic peerhood itself, then Conciliationism makes contradictory demands and paradoxes arise.

Existing research suggests that people's judgments of actual causation can be influenced by the degree to which they regard certain events as normal. We develop an explanation for this phenomenon that draws on standard tools from the literature on graphical causal models and, in particular, on the idea of probabilistic sampling. Using these tools, we propose a new measure of actual causal strength. This measure accurately captures three effects of normality on causal judgment that have been observed in existing studies. (...) More importantly, the measure predicts a new effect ("abnormal deflation"). Two studies show that people's judgments do, in fact, show this new effect. Taken together, the patterns of people's causal judgments thereby provide support for the proposed explanation. (shrink)

A growing number of decision theorists have, in recent years, defended the view that rationality is permissive under risk: Different rational agents may be more or less risk-averse or risk-inclined. This can result in them making different choices under risk even if they value outcomes in exactly the same way. One pressing question that arises once we grant such permissiveness is what attitude to risk we should implement when choosing on behalf of other people. Are we permitted to implement any (...) of the rationally permissible risk attitudes, is there some specific risk attitude that is required when choosing for others, or are we required to defer to the risk attitudes of the people on whose behalf we are choosing? This article elaborates on this question, explains its wider practical and theoretical significance, provides an overview of existing answers, and explores how to go about providing a more systematic account of how to choose on behalf of others in risky contexts.

Cet essai présente une description de plusieurs travaux inédits de Jacques Derrida au sujet de Marx et d'Althusser datant des années 1960 et 1970. Au-delà du travail philologique, il s'agit aussi d'une étude théorique de notions telles que 'idéologie', 'fétichisme', 'reproduction', 'division du travail', 'différence sexuelle', 'domination', 'économie politique', 'matérialisme dialectique', ou 'production culturelle' — tout autant à travers les textes marxistes que dans les lectures déconstructives qu'en propose alors Derrida. Durant les années 1970, dans le cadre de son séminaire, (...) Derrida s'efforce de penser une autre économie politique, au-delà de l'économie du propre qu'il identifie aussi bien chez les économistes classiques que chez leurs critiques marxistes. Ces lectures détaillées et combattives de textes marxistes restent aujourd'hui inédites. Leur prise en compte contribue à redéfinir l'image de Derrida et de la déconstruction, en témoignant de ses discussions très avancées de Marx, d'Althusser, et de la pensée marxiste — et ce dès la fin des années 1960 et le début des années 1970, plus de 20 ans avant la publication de Spectres de Marx (1993). -/- Une version plus courte de cet article fut traduite en espagnol par Ramiro Parodi, et publiée en 2019 dans le numéro 7 de la revue Demarcaciones — numéro consacré au 25ème anniversaire de la publication de Spectres de Marx.

The picture of L. Appuleius Saturninus' last days is usually derived from the straightforward narrative account found in Appian's Civil Wars, an account which modern analysis has shown to be flawed. That narrative may be glossed as follows. At the consular elections for the year 99, Saturninus and Glaucia instigated the death of a more hopeful contender. Chaos followed. On the following day, when the People had made its intention to do away with the ‘malefactors’ absolutely plain, Saturninus, Glaucia and (...) the quaestor Saufeius seized the Capitol with followers from the country. The Senate voted for their suppression and Marius invested the hill. With hopes of a safe conduct, the beseiged surrendered and Marius detained them in the curia.

Typically, nudging is a technique for steering the choices of people without giving reasons or using enforcement. In benevolent cases, it is used when people are insufficiently responsive to reason. The nudger triggers automatic cognitive mechanisms – sometimes even biases – in smart ways in order to push irrational people in the right direction. Interestingly, this technique can also be applied to doxastic attitudes. Someone who is doxastically unresponsive to evidence can be nudged into forming true beliefs or doxastic attitudes (...) that are propositionally justified. When doxastic nudging uses non-rational mechanisms, the worry is that nudging cannot result in justified beliefs or knowledge, as the resulting doxastic attitudes lack the right kind of basis. In this paper, I will argue that given the right background views about knowledge, justified beliefs and the relevant processes, epistemic nudging is possible even in these cases. That is, all kinds of nudging can – in appropriate circumstances – produce justified beliefs or knowledge in the nudgee. (shrink)
