For more than 20 years, research has proven the beneficial effect of natural frequencies when it comes to solving Bayesian reasoning tasks (Gigerenzer & Hoffrage, 1995). In a recent meta-analysis, McDowell & Jacobs (2017) showed that presenting a task in natural frequency format increases performance rates to 24% compared to only 4% when the same task is presented in probability format. Nevertheless, on average three quarters of participants in their meta-analysis failed to obtain the correct solution for such a task (...) in frequency format. In this paper, we present an empirical study on what participants typically do wrong when confronted with natural frequencies. We found that many of them did not actually use natural frequencies for their calculations, but translated them back into complicated probabilities instead. This switch from the intuitive presentation format to a less intuitive calculation format will be discussed within the framework of psychological theories (e.g., the Einstellung effect). (shrink)

In teaching statistics in secondary schools and at university, two visualizations are primarily used when situations with two dichotomous characteristics are represented: 2×2 tables and tree diagrams. Both visualizations can be depicted either with probabilities or with frequencies. Visualizations with frequencies have been shown to help students significantly more in Bayesian reasoning problems than probability visualizations do. Because tree diagrams or double-trees (which are largely unknown in school) are node-branch-structures, these two visualizations (compared to the 2×2 table) can even simultaneously (...) display probabilities on branches and frequencies inside the nodes. This is a teaching advantage as it allows the frequency concept to be used to better understand probabilities. However, 2×2 tables and (double-) trees have a decisive disadvantage: While joint probabilities (e.g., P(AB)) are represented in 2×2 tables but no conditional probabilities (e.g., P(A|B)), it is exactly the other way around with (double-) trees. Therefore, a visualization that is equally suitable for the representation of joint probabilities and conditional probabilities is desirable. In this article, we present a new visualization—the frequency net—in which all absolute frequencies and all types of probabilities can be depicted. In addition to a detailed theoretical analysis of the frequency net, we report the results of a study with 249 university students that shows that “net diagrams” can improve reasoning without previous instruction to a similar extent as 2×2 tables and double-trees. Regarding questions about conditional probabilities, frequency visualizations (2×2 table, double-tree, or net diagram with natural frequencies) are consistently superior to probability visualizations. The frequency net performs as well as the frequency double-tree. Only the 2×2 table with frequencies—the only visualization that participants were already familiar with —led to higher performance rates. If, on the other hand, a question about a joint probability had to be answered, all implemented visualizations clearly supported participants’ performance, and no uniform format effect becomes visible. Participants reached the highest performance in the versions with probability 2×2 tables and probability net diagrams. Furthermore, after conducting a detailed error analysis, we report interesting error shifts between the two information formats and the different visualizations and give recommendations for teaching probability.

Various philosophers have wanted to move from a (P.F.) “Strawsonian” understanding of the “practices of moral responsibility” to a non-skeptical result. I focus on a strategy moving from a “response-dependent” theory of responsibility. I aim to show that a key analogy associated with this strategy fails to support a compatibilist result. It seems clear that nothing could show that nothing we have been laughing at has really been funny. If “the funny” is similar to “the blameworthy”, then perhaps it would (...) follow that nothing could show that no one we have ever blamed has really been blameworthy. The comparison is interesting, but inconclusive: even if we grant that these properties are normatively similar, the latter has substantive empirical presuppositions, whereas the former does not. One important upshot: even if the standards operative in our practices cannot be mistaken, it could nevertheless be that no one has ever met these standards Ruling out this possibility seemingly requires re-engaging in all of the so-called "metaphysical" debates Strawsonians are keen to avoid.

Moral latitude is only ever a matter of coincidence on the most popular decision procedure in the literature on moral uncertainty. In all possible choice situations other than those in which two or more options happen to be tied for maximal expected choiceworthiness, Maximize Expected Choiceworthiness implies that only one possible option is uniquely appropriate. A better theory of appropriateness would be more sensitive to the decision maker’s credence in theories that endorse agent-centred prerogatives. In this paper, we will develop (...) and defend a modified version of this view that allows for agent-centred prerogatives and supererogation as part of its verdicts about appropriateness. (shrink)

Joe Horton argues that partial aggregation yields unacceptable verdicts in cases with risk and multiple decisions. I begin by showing that Horton’s challenge does not depend on risk, since exactly similar arguments apply to riskless cases. The underlying conflict Horton exposes is between partial aggregation and certain principles of diachronic choice. I then provide two arguments against these diachronic principles: they conflict with intuitions about parity, prerogatives, and cyclical preferences, and they rely on an odd assumption about diachronic choice. Finally, (...) I offer an explanation, on behalf of partial aggregation, for why these diachronic principles fail. (shrink)

It remains controversial whether touch is a truly spatial sense or not. Many philosophers suggest that, if touch is indeed spatial, it is only through its alliances with exploratory movement, and with proprioception. Here we develop the notion that a minimal yet important form of spatial perception may occur in purely passive touch. We do this by showing that the array of tactile receptive fields in the skin, and appropriately relayed to the cortex, may contain the same basic informational building (...) blocks that a creature navigating around its environment uses to build up a perception of space. We illustrate this point with preliminary evidence that perception of spatiotemporal patterns on the human skin shows some of the same features as spatial navigation in animals. We argue (a) that the receptor array defines a ‘tactile field’, (b) that this field exists in a minimal form in ‘skin space’, logically prior to any transformation into bodily or external spatial coordinates, and (c) that this field supports tactile perception without integration of concurrent proprioceptive or motor information. The basic cognitive elements of space perception may begin at lower levels of neural and perceptual organisation than previously thought. (shrink)

Interactions in service ecosystems, as opposed to the service dyad, have recently gained much attention from research. However, it is still unclear how they influence a customer’s experiential value and trigger desired prosocial behavior. The purpose of this study is to identify which elements of the multi-actor service ecosystem contribute to a customer’s experiential value and to investigate its relation to a customer’s interaction attitude and inter-customer helping behavior. The authors adopted a scale development procedure from the existing literature. Service, (...) brand, retail and tourism management research as well as expert feedback is used to generate a pool of 33 items. Exploratory and confirmatory factor analysis were conducted. The scale was validated based on more than 468 responses to a CASI at one of the world’s largest trade shows. Scale-development procedure was followed by structural equation modeling. CFA supports that experiential value in multi-actor ecosystems comprises five dimensions. The functional value of personnel, the perception of other customers’ appearance, the perception of other customers’ behavior, multisensory stimuli, and a customer’s enjoyment. Experiential value positively and directly relates to a customer’s interaction attitude and inter-customer helping behavior. Furthermore, the effect of experiential value on inter-customer helping behavior is partially mediated by interaction attitude. Managers interested in getting more out of interactions with customers will develop an understanding for the interplay between the physical environment and individuals within a multi-actor ecosystem. Social scientists and managers can use the scale to assess experiential value, encourage a customer’s interaction attitude and utilize the customers’ influence on their peers. This paper synthesizes insights from existing research on experiential value, from various fields, in one scale. This holistic approach is the first to simultaneously account for a customer’s interactions with the multisensory physical environment, personal interactions with employees and interactions between customers in a multi-actor service ecosystem.

The Hong and Page ‘diversity trumps ability’ result has been used to argue for the more general claim that a diverse set of agents is epistemically superior to a comparable group of experts. Here we extend Hong and Page’s model to landscapes of different degrees of randomness and demonstrate the sensitivity of the ‘diversity trumps ability’ result. This analysis offers a more nuanced picture of how diversity, ability, and expertise may relate. Although models of this sort can indeed be suggestive (...) for diversity policies, we advise against interpreting such results overly broadly. (shrink)

One prominent welfarist axiology, critical-level utilitarianism, says that individual lives must surpass a specified ‘critical level’ in order to make a positive contribution to the comparative status of a given population. In this article I develop a new dilemma for critical-level utilitarians. When comparatively evaluating populations composed of different species, critical-level utilitarians must decide whether the critical level is a universal threshold or whether the critical level is a species-relative threshold. I argue that both thresholds lead to a range of (...) axiological puzzles and objections as yet undiscussed within the literature, and therefore conclude that critical-level utilitarianism should not be taken as a morally plausible welfarist axiology. I show that certain competitive formulations of critical range utilitarianism are subject to the argument too, and that further attempts to relativise critical levels to a particular group or category of welfare bearer are unsustainable.

Conceptual Engineering alleges that philosophical problems are best treated via revising or replacing our concepts (or words). The goal here is not to defend Conceptual Engineering but rather show that it can (and should) invoke Neutralism—the broad view that philosophical progress can take place when (and sometimes only when) a thoroughly neutral, non-specific theory, treatment, or methodology is adopted. A neutralist treatment of one form of skepticism is used as a case study and is compared with various non-neutral rivals. Along (...) the way, a new taxonomy for paradox is proposed. (shrink)

This article revisits an oft-studied phenomenon from the vantage point of the phenomenology of Merleau-Ponty, Keen, and Giorgi. The protocols used have been taken from the first comprehensive academic study conducted on the runner’s high phenomenon. Throughout its experimental study, the runner’s high has remained a poorly understood phenomenon. Possible reasons for this are considered alongside the phenomenological analysis. Considered phenomenologically, the runner’s high is an experience of the absence of the limitations of body, time, and space. It is experienced (...) on the backdrop of a typical run experience which is characterized by familiar pains and labor. However, in the event of the runner’s high the familiar pains and labor do not present, making the runner’s high an experience of absence. Since these limitations play a role of restriction, their absence is pleasurable. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 44.4 (2006) 623-634 MuseSearchJournalsThis JournalContents[Access article in PDF]Character and Evil in Kant's Moral AnthropologyPatrick FriersonIn the Metaphysics of Morals, Kant explains that moral anthropology studies the "subjective conditions in human nature that help or hinder [people] in fulfilling the laws of a metaphysics of morals" and insists that such anthropology "cannot be dispensed with" (6:217).1 But it is often difficult to find clear (...) evidence of this sort of anthropology in Kant's own works. In this paper, I discuss Kant's account of character as an example of Kantian moral anthropology.Kant's account of character is one of the most important parts of his Anthropology from a Pragmatic Point of View.2 Kant describes the character of the person, in particular, as the "distinguishing mark of the human being as a rational being endowed with freedom" and says that character "indicates what the human being is prepared to make of himself" (7:285). Recently, Kant commentators have gone even further. G. Felicitas Munzel, for example, claims that character is "the systematic link between the moral, aesthetic, and anthropological elements of Kant's works."3 This paper will not investigate the full richness of Kant's account of character. Instead, I focus on one particular problem that arises in Kant's discussion of character—an apparent conflict between the moral relevance of character and the possibility of evil character. By showing why there is an apparent conflict and why it is merely apparent, I show some of the ways in which a particular subjective condition in human nature can help, but not force, people to fulfill the laws of a metaphysics of morals. [End Page 623]1. The Problem: Moral Character and the Case of SullaWhen Kant introduces character in the Anthropology, he distinguishes between the character of the person, of the sex, of the nation, of the race, and of the species. Even within the character of the person, he distinguishes between "natural aptitude," "temperament," and "character purely and simply," all of which are different kinds of individual character. But only the last—the "character purely and simply"4 of a person—"is moral" and "shows what man is prepared to make of himself" (7:285).5 This paper focuses only on that general, moral character.At first, Kant seems to describe general character as morally good. Twice in his opening discussion of character, Kant describes "character" (Charakter) as "moral" (moralische) (7:285), and he insists that "character has an inner worth, and is beyond all price" (7:292). Though not decisive, these comments suggest that one with character has a good will. But Kant goes further, adding that the person with character "relies on principles that are valid for everyone" (7:293). This reference to universally valid principles is picked up later in a way that highlights its moral goodness.For character requires maxims that proceed from reason and morally-practical principles. Therefore one cannot rightly say that the malice of this human being is a quality of his character; for then it would be diabolic. The human being, however, never sanctions the evil in himself, and so there is actually no malice from principles; but only from the forsaking of them.(7:293–94)It seems that Kant could not be more explicit. Character seems to involve acting on the basis of principles that conform to and even flow from "morally-practical principles," which he seems to distinguish from anything evil. This seems quite close to Kant's account of the good will as a will "whose principle is the categorical imperative" (4:444). (Although Kant's precise account of the good will is complicated, for our purposes here it is sufficient to define a good will as a will that consistently acts out of respect for the moral law.6) To have character, it would seem, is to have a good will.But this apparent identification of character with good character does not fit the rest of...

In Replacing Truth, Scharp takes the concept of truth to be fundamentally incoherent. As such, Scharp reckons it to be unsuited for systematic philosophical theorising and in need of replacement – at least for regions of thought and talk which permit liar sentences and their ilk to be formulated. This replacement methodology is radical because it not only recommends that the concept of truth be replaced, but that the word ‘true’ be replaced too. Only Tarski has attempted anything like it (...) before. I dub such a view Conceptual Marxism. In assessing this view, my goals are fourfold: to summarise the many components of Scharp’s theory of truth; to highlight what I take to be some of the excess baggage carried by the view; to assess whether, and to what extent, the extreme methodology on offer is at all called for; finally, to briefly propose a less radical replacement strategy for resolving the liar paradox.

We model scientific theories as Bayesian networks. Nodes carry credences and function as abstract representations of propositions within the structure. Directed links carry conditional probabilities and represent connections between those propositions. Updating is Bayesian across the network as a whole. The impact of evidence at one point within a scientific theory can have a very different impact on the network than does evidence of the same strength at a different point. A Bayesian model allows us to envisage and analyze the (...) differential impact of evidence and credence change at different points within a single network and across different theoretical structures.

A small consortium of philosophers has begun work on the implications of epistemic networks (Zollman 2008 and forthcoming; Grim 2006, 2007; Weisberg and Muldoon forthcoming), building on theoretical work in economics, computer science, and engineering (Bala and Goyal 1998, Kleinberg 2001; Amaral et. al., 2004) and on some experimental work in social psychology (Mason, Jones, and Goldstone, 2008). This paper outlines core philosophical results and extends those results to the specific question of thresholds. Epistemic maximization of certain types does show (...) clear threshold effects. Intriguingly, however, those effects appear to be importantly independent from more familiar threshold effects in networks. (shrink)

In this article, the authors examine post-concussion syndrome (PCS) from an existential-phenomenological perspective, specifically as a Heideggerian analysis of Dasein (or Daseinsanalysis; Condrau, 1988). As a medical syndrome, PCS was once defined in terms of its pathophysiology. However, in the absence of reliable evidence of pathophysiology, PCS has been removed from the DSM-5. We have suspended the natural attitude, in this case the biomedical model, and have taken seriously the symptoms of PCS as indications that meaningful changes have occurred within (...) the structure of the patient’s existence. Following the medical theories of Goldstein (1995) and Gadamer (1996), the authors describe the significance of PCS as it is lived by Tyrese, an NCAA Division II football player whose series of concussions left him permanently sidelined. Careful consideration is paid to the existential dimensions of the syndrome, specifically the backgrounds of temporality, sociality, and attunement. In conclusion, a new approach to rehabilitation is explored. (shrink)

When incorporating the environment into mental processing (cf., cognitive offloading), one creates novel cognitive strategies that have the potential to improve task performance. Improved performance can, for example, mean faster problem solving, more accurate solutions, or even higher grades at university.1 Although cognitive offloading has frequently been associated with improved performance, it is yet unclear how flexible problem solvers are at matching their offloading habits with their current performance goals (can people improve goal‐related instead of generic performance, e.g., when being (...) in a hurry and aiming for a “quick and dirty” solution?). Here, we asked participants to solve a cognitive task, provided them with different goals—maximizing speed (SPD) or accuracy (ACC), respectively—and measured how frequently (Experiment 1) and how proficiently (Experiment 2) they made use of a novel external resource to support their cognitive processing. Experiment 1 showed that offloading behavior varied with goals: Participants offloaded less in the SPD than in the ACC condition. Experiment 2 showed that this differential offloading behavior was associated with high goal‐related performance: fast answers in the SPD, accurate answers in the ACC condition. Simultaneously, goal‐unrelated performance was sacrificed: inaccurate answers in the SPD, slow answers in the ACC condition. The findings support the notion of humans as canny offloaders who are able to successfully incorporate their environment in pursuit of their current cognitive goals. Future efforts should be focused on the finding's generalizability, for example, to settings without feedback or with high mental workload. (shrink)

Cet article s’interroge sur les raisons pour lesquelles Kafka a pu écrire Le Terrier dans la période berlinoise de son existence, ce qui amène à réfléchir sur la possibilité d’une lecture allégorique de Kafka.

Et comment cette excavation reprend-elle, pour la déconstruire, l’élévation de la tour de Babel? L’une (...) des hypothèses suivie ici est que cette construction figure le travail de la fiction, de l’imaginaire, et que le sifflement qui vient en interrompre la clôture donne à comprendre l’impossibilité d’en finir avec le dehors, l’existence d’une altérité qui défait la perfection du travail de l’imaginaire.

The Polymath Project is an online collaborative enterprise that was initiated in 2009, when Timothy Gowers asked whether and how groups could work together to solve mathematical problems that “do not naturally split up into a vast number of subtasks.” Gowers proposed to answer this question himself by actually trying to set up such a collaboration, based on interactions taking place in the comment-threads of a series of posts on a WordPress blog. Hence, the first project officially started in early (...) 2009, to be proclaimed successful only 6 weeks later (Gowers and Nielsen 2009). From its inception until April 2018, 15 more Polymath problems (and a handful of smaller or related ones) have been launched. These projects have attracted attention from different scholarly communities, including the philosophy of mathematical practices, from the perspective of which the Polymath Project can be seen as a vast repository of mathematics in action. This chapter continues previous work by its authors on the topic in question and topics related. More specifically, for the purposes of this volume, it is our aim to both summarize and expand upon these earlier contributions. The starting point is the above observation that in the past decade, the issue of “massively collaborative mathematics” (to be qualified below) has drawn quite some attention. However, does it also warrant intensive philosophical attention in particular? For, as exciting as these developments might be from mathematical and other points of view, the enhanced possibilities that have come with it do not per se give rise to any philosophical import. In Van Bendegem (2011), one of us has indeed tentatively argued for the philosophical relevance of these new dynamics of proof construction flowing from the wide availability and efficiency of Internet technology. We shall below briefly rehearse and update the argument given there. (shrink)

Tschacher and Haken have recently applied a systems-based approach to modeling psychotherapy process in terms of potentially beneficial tendencies toward deterministic as well as chaotic forms of change in the client’s behavioral, cognitive and affective experience during the course of therapy. A chaotic change process refers to a greater exploration of the states that a client can be in, and it may have a potential positive role to play in their development. A distinction is made between on the one hand, (...) specific instances of instability which are due to techniques employed by the therapist, and on the other, a more general instability which is due to the therapeutic relationship, and a key, necessary result of a successful therapeutic alliance. Drawing on Friston’s systems-based model of free energy minimization and predictive coding, it is proposed here that the increase in the instability of a client’s functioning due to therapy can be conceptualized as a reduction in the precisions with which the client’s prior beliefs about themselves and their world, are held. It is shown how a good therapeutic alliance results in the emergence of a new hierarchical level in the client’s generative model of themselves and their relationship with the world. The emergence of this new level of functioning permits the reduction of the precisions of the client’s priors, which allows the client to ‘open up’: to experience thoughts, emotions and experiences they did not have before. It is proposed that this process is a necessary precursor to change due to psychotherapy. A good consilience can be found between this approach to understanding the role of the therapeutic alliance, and the role of epistemic trust in psychotherapy as described by Fonagy and Allison. It is suggested that beneficial forms of instability in clients are an underappreciated influence on psychotherapy process, and thoughts about the implications, as well as situations in which instability may not be beneficial for therapy, are considered.

The iterated Prisoner’s Dilemma has become the standard model for the evolution of cooperative behavior within a community of egoistic agents, frequently cited for implications in both sociology and biology. Due primarily to the work of Axelrod (1980a, 198Ob, 1984, 1985), a strategy of tit for tat (TFT) has established a reputation as being particularly robust. Nowak and Sigmund (1992) have shown, however, that in a world of stochastic error or imperfect communication, it is not TFT that finally triumphs in (...) an ecological model based on population percentages (Axelrod and Hamilton 1981), but ‘generous tit for tat’ (GTFT), which repays cooperation with a probability of cooperation approaching 1 but forgives defection with a probability of l/3. In this paper, we consider a spatialized instantiation of the stochastic Prisoner’s Dilemma, using two-dimensional cellular automata (Wolfram, 1984, 1986; Gutowitz, 1990) to model the spatial dynamics of populations of competing strategies. The surprising result is that in the spatial model it is not GIFT but still more generous strategies that are favored. The optimal strategy within this spatial ecology appears to be a form of ‘bending over backwards’, which returns cooperation for defection with a probability of 2/3 - a rate twice as generous as GTFT.

After situating Andreas Reckwitz’s The Society of Singularities within the broader context of the tradition of social theory, we discuss in detail the obvious strengths of this book, notably its impressive range and originality. Subsequently, we elaborate on two limitations of Reckwitz’s argument. Firstly, we argue that Reckwitz’s use of categories such as ‘singularity’ and ‘universality’ is too all-embracing, lacking the clarity and focus needed to sustain a productive line of inquiry. Secondly, and related to the previous point, we contend (...) that Reckwitz’s claims about the recent trend towards increasing singularity are so broad that they are difficult to refute empirically. Further, we discuss briefly contemporary political developments to demonstrate why the core societal issues at stake cannot be explained through all-inclusive categories such as singularity. Finally, we maintain that existence theory can provide an alternative fruitful perspective on some of the phenomena discussed in this book. (shrink)

The distinction between distributive and non-distributive profiles figures prominently in current evaluations of the ethical and epistemological risks that are associated with automated profiling practices. The diagnosis that non-distributive profiles may coincidentally situate an individual in the wrong category is often perceived as the central shortcoming of such profiles. According to this diagnosis, most risks can be retraced to the use of non-universal generalisations and various other statistical associations. This article develops a top-down analysis of non-distributive profiles in which this (...) fallibility of non-distributive profiles is no longer central. Instead, it focuses on how profiling creates various asymmetries between an individual data-subject and a profiler. The emergence of informational, interest, and perspectival asymmetries between data-subject and profiler explains how non-distributive profiles weaken the epistemic position of a profiled individual. This alternative analysis provides a more balanced assessment of the epistemic risks associated with non-distributive profiles. (shrink)

A number of critics have argued that Berkeley's metaphysics can offer no tenable account of human agency. In this paper I argue that Berkeley does have a coherent account of action. The paper addresses arguments by C.C. W. Taylor, Robert Imlay, and Jonathan Bennett. The paper attempts to show that Berkeley can offer a theory of action, maintain many of our common intuitions about action, and provide a defensible solution to the problem of evil.

Complexe, énigmatique car radicalement novatrice, la pensée nietzschéenne donne le sentiment d'être trop dispersée pour pouvoir être saisissable. Du reste, y a-t-il un ou plusieurs Nietzsche? Celui de L'Antéchris et d'Ecce Homo est-il le même que celui de La Naissance de la tragédie? Mais complexe ne signifie pas chaotique, et l'incertitude se dissipe si l'on repère les moments où se constituent ses positions fondamentales: quand la notion de pulsion se met-elle en place? Avec quel ouvrage la théorie des valeurs apparaît-elle? (...) À quel moment la logique du sentiment de puissance est-elle identifiée? Quand la philosophie est-elle comprise comme un dire-oui? Dans quel livre la tentative de lire la réalité tout entière comme volonté de puissance se fait-elle jour? Cet ouvrage apporte une réponse à ces questions. Il caractérise l'apport des principaux textes de Nietzsche, et montre que l'évolution de sa réflexion n'est pas faite de revirements ni d'abandons de thèses au profit de thèses nouvelles, mais d'un affinement progressif au sein d'une problématique invariante: conquête d'un mode de pensée réformé dont les grandes lignes sont dessinées dès son premier livre, La Naissance de la tragédie"--Page 4 of cover.

L'ambition de cet ouvrage est d'éclairer la figure du philosophe telle que Nietzsche la redéfinit à travers dix études, chacune articulée autour d'une notion clé de la réflexion nietzschéenne. Ce que Nietzsche appelle la "philosophie de l'avenir" ne désigne pas un genre ni une variante de la philosophie, mais explicite la notion même de philosophie, une fois celle-ci mise en accord avec son exigence de radicalité en matière de questionnement - ambition que, selon Nietzsche, les philosophes ne sont jamais parvenus (...) à réaliser véritablement. Habitée par cette exigence, la philosophie se doit de prendre pour objet de réflexion ce qu'il y a de plus radical, ce qui conditionne toute pensée et plus largement toute activité humaine - c'est-à-dire le mode de conditionnement lui-même, ce que Nietzsche désigne par le terme de "valeurs". A titre de conséquence, on découvre alors que c'est le façonnement de l'homme et l'élaboration d'une nouvelle forme de vie qui est au coeur de son entreprise. (shrink)

Food uncertainty has the effect of invigorating food-related responses. Psychologists have noted that mammals and birds respond more to a conditioned stimulus that unreliably predicts food delivery, and ecologists have shown that animals consume and/or hoard more food and can get fatter when access to that resource is unpredictable. Are these phenomena related? We think they are. Psychologists have proposed several mechanistic interpretations, while ecologists have suggested a functional interpretation: The effect of unpredictability on fat reserves and hoarding behavior is (...) an evolutionary strategy acting against the risk of starvation when food is in short supply. Both perspectives are complementary, and we argue that the psychology of incentive motivational processes can shed some light on the causal mechanisms leading animals to seek and consume more food under uncertainty in the wild. Our theoretical approach is in agreement with neuroscientific data relating to the role of dopamine, a neurotransmitter strongly involved in incentive motivation, and its plausibility has received some explanatory and predictive value with respect to Pavlovian phenomena. Overall, we argue that the occasional and unavoidable absence of food rewards has motivational effects that facilitate foraging effort. We show that this hypothesis is computationally tenable, leading foragers in an unpredictable environment to consume more food items and to have higher long-term energy storage than foragers in a predictable environment.

ABSTRACT In this article I consider alternate but often complementary models for women’s republicanism from those discussed by Sandrine Bergès. In particular, I make use of Bergès’s insights about extending philosophical inquiry beyond traditional texts to analyse how militant political action was both informed by and informed the creation of philosophical texts, and consider the possibility of bringing direct action into the realm of philosophical investigation.

Primeaux and Stieber clearly articulate that good ethics maximize profits. The authors show that in the long run business must operate within the value systems of a society.

Our scientific theories, like our cognitive structures in general, consist of propositions linked by evidential, explanatory, probabilistic, and logical connections. Those theoretical webs ‘impinge on the world at their edges,’ subject to a continuing barrage of incoming evidence. Our credences in the various elements of those structures change in response to that continuing barrage of evidence, as do the perceived connections between them. Here we model scientific theories as Bayesian nets, with credences at nodes and conditional links between them modelled (...) as conditional probabilities. We update those networks, in terms of both credences at nodes and conditional probabilities at links, through a temporal barrage of random incoming evidence. Robust patterns of punctuated equilibrium, suggestive of ‘normal science’ alternating with ‘paradigm shifts,’ emerge prominently in that change dynamics. The suggestion is that at least some of the phenomena at the core of the Kuhnian tradition are predictable in the typical dynamics of scientific theory change captured as Bayesian nets under even a random evidence barrage.
