An essay review of Michael Weisberg's Simulation and Similarity.

"Why should we care about having true beliefs? And why do demonstrably false beliefs persist and spread despite consequences for the people who hold them? Philosophers of science Cailin O’Connor and James Weatherall argue that social factors, rather than individual psychology, are what’s essential to understanding the spread and persistence of false belief. It might seem that there’s an obvious reason that true beliefs matter: false beliefs will hurt you. But if that’s right, then why is it irrelevant (...) to many people whether they believe true things or not? In an age riven by "fake news," "alternative facts," and disputes over the validity of everything from climate change to the size of inauguration crowds, the authors argue that social factors, not individual psychology, are what’s essential to understanding the persistence of false belief and that we must know how those social forces work in order to fight misinformation effectively."–Publisher’s description.

Diversity of practice is widely recognized as crucial to scientific progress. If all scientists perform the same tests in their research, they might miss important insights that other tests would yield. If all scientists adhere to the same theories, they might fail to explore other options which, in turn, might be superior. But the mechanisms that lead to this sort of diversity can also generate epistemic harms when scientific communities fail to reach swift consensus on successful theories. In this paper, (...) we draw on extant literature using network models to investigate diversity in science. We evaluate different mechanisms from the modeling literature that can promote transient diversity of practice, keeping in mind ethical and practical constraints posed by real epistemic communities. We ask: what are the best ways to promote an appropriate amount of diversity of practice in scientific communities? (shrink)

In this paper we use an experimental approach to investigate how linguistic conventions can emerge in a society without explicit agreement. As a starting point we consider the signaling game introduced by Lewis. We find that in experimental settings, small groups can quickly develop conventions of signal meaning in these games. We also investigate versions of the game where the theoretical literature indicates that meaning will be less likely to arise—when there are more than two states for actors to transfer (...) meaning about and when some states are more likely than others. In these cases, we find that actors are less likely to arrive at strategies where signals have clear conventional meaning. We conclude with a proposal for extending the use of the methodology of experimental economics in experimental philosophy. (shrink)

Collaboration is increasingly popular across academia. Collaborative work raises certain ethical questions, however. How will the fruits of collaboration be divided? How will the work for the collaborative project be split? In this paper, we consider the following question in particular. Are there ways in which these divisions systematically disadvantage certain groups? -/- We use evolutionary game theoretic models to address this question. First, we discuss results from O'Connor and Bruner (unpublished). In this paper, we show that underrepresented groups in (...) academia can be disadvantaged in such situations by dint of their small numbers. Second, we present novel results exploring how the hierarchical structure of academia can lead to bargaining disadvantage. We investigate models where one actor has a higher baseline of academic success, less to lose if collaboration goes south, or greater rewards for non-collaborative work. We show that in these situations, the less powerful partner is disadvantaged in bargaining over collaboration. (shrink)

This article uses sim-max games to model perceptual categorization with the goal of answering the following question: To what degree should we expect the perceptual categories of biological actors to track properties of the world around them? I argue that an analysis of these games suggests that the relationship between real-world structure and evolved perceptual categories is mediated by successful action in the sense that organisms evolve to categorize together states of nature for which similar actions lead to similar results. (...) This conclusion indicates that both strongly realist and strongly antirealist views about perceptual categories are too simple. (shrink)

Contemporary societies are often “polarized”, in the sense that sub-groups within these societies hold stably opposing beliefs, even when there is a fact of the matter. Extant models of polarization do not capture the idea that some beliefs are true and others false. Here we present a model, based on the network epistemology framework of Bala and Goyal, 784–811 1998), in which polarization emerges even though agents gather evidence about their beliefs, and true belief yields a pay-off advantage. As we (...) discuss, these results are especially relevant to polarization in scientific communities, for these reasons. The key mechanism that generates polarization involves treating evidence generated by other agents as uncertain when their beliefs are relatively different from one’s own. (shrink)

In their recent book, Oreskes and Conway describe the ‘tobacco strategy’, which was used by the tobacco industry to influence policymakers regarding the health risks of tobacco products. The strategy involved two parts, consisting of promoting and sharing independent research supporting the industry’s preferred position and funding additional research, but selectively publishing the results. We introduce a model of the tobacco strategy, and use it to argue that both prongs of the strategy can be extremely effective—even when policymakers rationally update (...) on all evidence available to them. As we elaborate, this model helps illustrate the conditions under which the tobacco strategy is particularly successful. In addition, we show how journalists engaged in ‘fair’ reporting can inadvertently mimic the effects of industry on public belief. 1Introduction2Epistemic Network Models3Selective Sharing4Biased Production5Journalists as Unwitting Propagandists6ConclusionAppendix.

Why do people who disagree about one subject tend to disagree about other subjects as well? In this paper, we introduce a model to explore this phenomenon of ‘epistemic factionization’. Agents attempt to discover the truth about multiple propositions by testing the world and sharing evidence gathered. But agents tend to mistrust evidence shared by those who do not hold similar beliefs. This mistrust leads to the endogenous emergence of factions of agents with multiple, highly correlated, polarized beliefs.

In a recent article, Carlos Santana shows that in common interest signaling games when signals are costly and when receivers can observe contextual environmental cues, ambiguous signaling strategies outperform precise ones and can, as a result, evolve. I show that if one assumes a realistic structure on the state space of a common interest signaling game, ambiguous strategies can be explained without appeal to contextual cues. I conclude by arguing that there are multiple types of cases of payoff-beneficial ambiguity, some (...) of which are better explained by Santana’s models and some of which are better explained by models presented here.

In response to those who argue for ‘property cluster’ views of natural kinds, I use evolutionary models of similarity-maximizing games to assess the claim that linguistic terms appropriately track sets of objects that cluster in property spaces. As I show, there are two sorts of ways this can fail to happen. First, evolved terms that do respect property structure in some senses can be conventional nonetheless. Second, and more crucially, because the function of linguistic terms is to facilitate successful action (...) in the world, when such success is based on something other than property clusters, we should not expect our terms to track those clusters. The models help make this second point salient by highlighting a dubious assumption underlying some versions of the cluster kinds view—that property clusters lead to successful generalization and induction in a straightforward way. As I point out, those who support property cluster kinds as natural can revert to a promiscuous realism in response to these observations. 1 Introduction2Cluster Kinds3Models and Results 3.1Similarity-maximizing games3.2Voronoi languages, clusters, and categories4Conventionality and Functionality in Kind Terms 4.1Conventional categories4.2Functionality and categories5Unnatural Perceptual Categories6The Payoff Relevance of Property Space7Conclusion.

Why do minority groups tend to be discriminated against when it comes to situations of bargaining and resource division? In this paper, I explore an explanation for this disadvantage that appeals solely to the dynamics of social interaction between minority and majority groups---the cultural Red King effect. As I show, in agent-based models of bargaining between groups, the minority group will tend to get less as a direct result of the fact that they frequently interact with majority group members, while (...) majority group members meet them only rarely. This effect is strengthened by certain psychological phenomenon---risk aversion and in-group preference---is robust on network models, and is strengthened in cases where pre-existing norms are discriminatory. I will also discuss how this effect unifies previous results on the impacts of institutional memory on bargaining between groups. (shrink)

Using evolutionary game theory, I consider how guilt can provide individual fitness benefits to actors both before and after bad behavior. This supplements recent work by philosophers on the evolution of guilt with a more complete picture of the relevant selection pressures.

We review several topics of philosophical interest connected to misleading online content. First we consider proposed definitions of different types of misleading content. Then we consider the epistemology of misinformation, focusing on approaches from virtue epistemology and social epistemology. Finally we discuss how misinformation is related to belief polarization, and argue that models of rational polarization present special challenges for conceptualizing fake news and misinformation.

We use tools from evolutionary game theory to examine how power might influence the cultural evolution of inequitable norms between discernible groups in a population of otherwise identical individuals. Similar extant models always assume that power is homogeneous across a social group. As such, these models fail to capture situations where individuals who are not themselves disempowered nonetheless end up disadvantaged in bargaining scenarios by dint of their social group membership. Thus, we assume that there is heterogeneity in the groups (...) in that some individuals are more powerful than others. Our model shows that even when most individuals in two discernible sub-groups are relevantly identical, powerful individuals can affect the social outcomes for their entire group; this results in power by association for their in-group and a bargaining disadvantage for their out-group. In addition, we observe scenarios like those described where individuals who are more powerful will get less in a bargaining scenario because a convention has emerged disadvantaging their social group.

In this paper we critically examine and seek to extend Philip Kitcher’s Ethical Project to weave together a distinctive naturalistic conception of how ethics came to occupy the place it does in our lives and how the existing ethical project should be revised and extended into the future. Although we endorse his insight that ethical progress is better conceived of as the improvement of an existing state than an incremental approach towards a fixed endpoint, we nonetheless go on to argue (...) that the metaethical apparatus Kitcher constructs around this creative metaethical proposal simply cannot do the work that he demands of it. The prospect of fundamental conflict between different functions of the ethical project requires Kitcher to appeal to a particular normative stance in order to judge specific changes in the ethical project to be genuinely progressive, and we argue that the virtues of continuity and coherence to which he appeals can only specify rather than justify the normative stance he favors. We conclude by suggesting an alternative approach for ethical naturalists that seems to us ultimately more promising than Kitcher’s own. (shrink)

Review of Peter Godfrey-Smith's Philosophy of Biology.

Book reviewed in this article: Suffering Presence: Theological Reflections on Medicine, the Mentally Handicapped, and the Church. By Stanley Hauerwas.

Background:The right of children to have their voice heard has been accepted by researchers, and there are increasing numbers of qualitative health studies involving children. The ethical and methodological issues of including children in research have caused worldwide concerns, and many researchers have published articles sharing their own experiences.Objectives:To systematically review and synthesise experts’ opinions and experiences about ethical and methodological issues of including children in research, as well as related solution strategies.Research design:The research design was a systematic (...) class='Hi'>review of opinion-based evidence, based on the guidelines by Joanna Briggs Institute.Methods:A search of five computerised databases has been conducted in April 2014 and 2271 articles were found. After screening the titles, abstracts, full texts and appraising the quality, 30 articles were finally included in the review. A meta-aggregative approach was applied in the data analysis and synthesis process.Ethical considerations:Ethical approval is not needed as it is a systematic review of published literature.Results:Six themes were identified, including evaluating potential risks and benefits, gaining access, obtaining informed consent/assent, protecting confidentiality and privacy, building rapport and collecting rich data. The similarities and differences between research involving children and that involving adults were indicated.Conclusion:All potential incentives should be justified when designing the study. Further studies need to research how to evaluate individual capacity of children and how to balance protecting children’s right to participate and their interests in the research. Cultural differences related to researching children in different regions should also be studied. (shrink)

We propose that revenge responses are often influenced more by affective reactions than by deliberate decision making as McCullough et al. suggest. We review social psychological evidence suggesting that justice judgments and reactions may be determined more by emotions than by cognitions.

Neo-Kantian philosophers see accountability as a key property of autonomy, or of social freedom more broadly. Autonomy, among those theorists, is, I contend, implicitly co-conceived with responsibility, producing a quasi-juridical conception of autonomy and a limiting notion of freedom. This article criticizes the connecting of freedom with accountability on a number of grounds. First, various conceptions of autonomy not only operate without a notion of accountability, but, in fact, would be impaired by an accountability requirement. Second, the neo-Kantians are unable (...) to defend the freedom enhancing properties that are supposedly brought about by the giving of reasons for one’s beliefs and actions. Third, the project of accountability is indifferent to personal outlooks, not because it takes a holistic perspective, but because of its interest in social convergence. (shrink)

This article is an attempt to situate imagination within consciousness complete with its own pre-cognitive, cognitive, and meta-cognitive domains. In the first sections we briefly review traditional philosophical and psychological conceptions of the imagination. The majority have viewed perception and imagination as separate faculties, performing distinct functions. A return to a phenomenological account of the imagination suggests that divisions between perception and imagination are transcended by precognitive factors of sense of reality and non-reality where perception and imagination play an (...) indivisible role. In fact, both imagination and perception define sense of reality jointly according to what is possible and not possible. Absorption in a possible world depends on the strengths of alternative possibilities, and the relationship between core and marginal consciousness. The model may offer a parsimonious account of different states and levels of imaginal consciousness, and of how “believed-in imaginings” develop and become under some circumstances “lived-in experiences.”.

In a review published in Vol. XVIII, No. I of Philosophical Books (January, 1977), Jenny Teichman remarks that, as most philosophy books are non-original, it is probably a good idea, now and again, to remind readers of the fact. Of dissertations I suspect that her statement is true with interest. Even so, it is still only the foolhardy or the naive and puf.e of heart who will ask, "Then why write them?" I mention Teichman's observation here so as to (...) be able to place this present dissertation with its fellows. But while only rarely will a book be original, and perhaps even less often a dissertation, this state of affairs need not preclude novelty on a more modest scale. At any rate, whatever may be the claims or disclaims to innovation by an author, it is the reader who, in the final analysis, will judge a work a legitimate pretender to innovation (large or small) and also judge the value of the new step. I have given this study its present title because it seems to me that the question of the extent to which the analytical work of G.E. Moore is consistent. with the disposition to realism inherent in his famous defense~~ ~ common sense is an important one in Moore's philosophy an~ perhaps, a question that has received less critical attention than it might have. In addressing that question here I have tried to show that, while Moore's insistence upon the literal truth of certain "views of common sense" does indeed commit him to a realist framework in metaphysical matters, this framework is flexible and allows for considerable, sometimes possibly surprising, freedom in deciding matters of detail. For instance, Moore's tendency, late in his career, to favor a phenomenalist analysis of material-object propositions forcefully compels us to ask the question of just how much a defense of common sense in philosophy commits the defender to. A similar question arises in regard to Moore's treatment of philosophical puzzles associated with the topic of 'abstract entities.' I will argue that, while Moore's work on metaphysical issues can, when collected, be termed 'realist' his concern was never with the correctness of realism as a system of thought, but rather with the soundness of individual arguments. In this kind of attention to the "small print" of philosophical arguments and in his recognition of the many questions of detail which have to be settled before a general position, whether realism or idealism or a third view, can be said to be either set forth or upheld, lies much of Moore's greatness as a philosopher.And, if there is an element of truth in the suggestion that Moore tended betimes not to see woods for trees, at least he never tended not to see trees for woods. And surely the latter is much the greater philosophical failing. (shrink)

Does law matter regarding public health outcomes? Regardless of what one may think about the answer to this age-old question, in recent years the public health community has increasingly demonstrated and recognized the roles that public health laws and policies play in effectuating long-lasting and broad-based population-wide changes. Public health laws and policies have been instrumental in the following ways: reducing smoking prevalence; reducing underage alcohol-related drinking, driving, crashes, and fatalities; reducing exposure to second-hand smoke; eliminating vaccine–associated paralytic poliomyelitis ; (...) increasing seat-belt use and reducing traffic fatalities; reducing dental carries; and reducing access to and consumption of unhealthy foods and beverages sold in schools and to reductions in caloric intake and overweight. In fact, in a review of the ten greatest public health achievements in the 20th century, all were influenced by policy change. (shrink)

Review of On a COlllplex Theory of a Simple God: An Investigation in Aquinas' Philosophical Theology, by Christopher M. Hughes.

The last 20 years have seen the development of a new form of therapy, compassion focused therapy. Although CFT has a growing evidence base, there have been few studies of CFT outside of an Anglo-European cultural context. In this paper, we ask: Might a CFT-based approach be of value for Indigenous Australians? If so, what kind of cultural adaptations might be needed? We report the findings from a pilot study of an arts-based compassion skills training group, in which usual CFT (...) group processes were significantly adapted to meet the needs of Indigenous Australians. At face value, CFT appeared to be a promising approach to enhancing the social and emotional wellbeing of Australia’s Indigenous peoples. However, despite initial consultations with Indigenous health professionals, the first attempts to offer a more conventional group-based CFT to Indigenous clients were largely unsuccessful. Following a review and advice from two Indigenous clients, we combined elements of CFT with visual arts to develop a new approach, “arts-based compassion skills training”. This paper reports an evaluation of this pilot ABCST group. The group had 6 × 4 h sessions of ABCST, facilitated by two psychologists and two artists. There were 10 participants, who attended between 2 and 6 sessions: five were clients, five were health professionals. Between 1 and 3 months later, six of the participants were interviewed. Qualitative analysis of interview data identified that two key processes—creating a positive group atmosphere and channeling compassion skills training through the medium of visual arts—led to four positive outcomes for participants: planting the seeds of new understandings, embodying the skills of compassion, strengthening relationships with others, and evolving a more self-compassionate relationship. We suggest that the preliminary results are sufficiently encouraging to warrant further development of ABCST in Indigenous communities. (shrink)

Exposure of man to chemical agents can occur intentionally, as in the treatment of disease, or inadvertently because the environment contains a wide range of synthetic or naturally occurring chemicals. The alkylating agents are a diverse group of compounds (Fig. 1) and comprise a good example of such xenobiotics, since much is known about their occurrence, and their biological effects include carcinogenicity, mutagenicity, toxicity and teratogenicity.Exposure to potentially carcinogenic alkylating agents such as nitrosamines may occur occupationally, from cigarette smoke, from (...) certain foodstuffs and even endogenously through the ingestion of the appropriate precursor chemicals.1 At the other extreme, the cytotoxic effects of agents such as the chloroethylating nitrosamides or mustards have been exploited in the design of certain antitumour drugs.2 The effectiveness of antitumour agents and the other, mostly adverse, biological effects of alkylating agents have been ascribed to their ability to damage cellular macromolecules, in particular DNA. This review concentrates on investigations carried out over the past two years on the role of DNA damage in carcinogenesis, but we shall see how recent advances in this area of research have also led to a better understanding of the mechanisms of the cytotoxic effects of alkylating antitumour agents.

Consider the idea of God in classical philosophical theology. God is a personal being perfect in every way: absolutely independent of everything, such that nothing exists apart from God's willing it to be so; unlimited in power and knowledge; perfectly blissful, lacking in nothing needed or desired; morally perfect. If such a being were to create, on what basis would He choose? Let us assume (as perfect being theologians generally do) that there is an objective, degreed property of intrinsic goodness, (...) such that every possible object is intrinsically good to some degree. We need not assume that this property is 'well ordered' in the sense that every object is comparable to every other, only that it is 'partially ordered' in the sense that every object belongs to one or another well ordered set of objects and has less goodness than God Himself. We thus replace the image of a linear 'great chain of being' with that of a branching structure whose branches reconnect only at their limit, which is God. And let us further suppose that whole systems of objects and their total histories -- possible worlds -- are likewise partially ordered by their intrinsic goodness. Now, if one or more of these creative options on each of the branches are of maximal overall value, is it inevitable that He would choose one of those? It seems passing strange that God would opt for less than the best when creating the best involves no cost at all. Yet supposing the choice of the best is inevitable for a perfect Creator seems at odds with the common assumption that God is perfectly free in choosing what He will. Perhaps, though, there is no set of one or more best creative choices. For every option, there is a better, with no finite upper bound on the ranked series. Here, matters are more puzzling. It appears that no matter which option God might choose, He must do so in the knowledge that there are options of arbitrarily greater value. It seems an odd constraint for a perfect being to have to live with.. (shrink)

The main thesis developed and defended in this superb book is that Hume implicitly "denies the existence . . . of a morally assessable god" (8), not just the existence of an overall "morally praiseworthy god" (8).

BackgroundThe ARRIVE (Animal Research: Reporting of In Vivo Experiments) guidelines are widely endorsed but compliance is limited. We sought to determine whether journal-requested completion of an ARRIVE checklist improves full compliance with the guidelines.MethodsIn a randomised controlled trial, manuscripts reporting in vivo animal research submitted to PLOS ONE (March–June 2015) were randomly allocated to either requested completion of an ARRIVE checklist or current standard practice. Authors, academic editors, and peer reviewers were blinded to group allocation. Trained reviewers performed outcome adjudication (...) in duplicate by assessing manuscripts against an operationalised version of the ARRIVE guidelines that consists 108 items. Our primary outcome was the between-group differences in the proportion of manuscripts meeting all ARRIVE guideline checklist subitems.ResultsWe randomised 1689 manuscripts (control: n = 844, intervention: n = 845), of which 1269 were sent for peer review and 762 (control: n = 340; intervention: n = 332) accepted for publication. No manuscript in either group achieved full compliance with the ARRIVE checklist. Details of animal husbandry (ARRIVE subitem 9b) was the only subitem to show improvements in reporting, with the proportion of compliant manuscripts rising from 52.1 to 74.1% (X2 = 34.0, df = 1, p = 2.1 × 10−7) in the control and intervention groups, respectively.ConclusionsThese results suggest that altering the editorial process to include requests for a completed ARRIVE checklist is not enough to improve compliance with the ARRIVE guidelines. Other approaches, such as more stringent editorial policies or a targeted approach on key quality items, may promote improvements in reporting. (shrink)

In almost every human society some people get more and others get less. Why is inequity the rule in human societies? Philosopher Cailin O'Connor reveals how cultural evolution works on social categories such as race and gender to generate unfairness.
