"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.

This is an Element surveying the most important literature using game theory and evolutionary game theory to shed light on questions in the philosophy of biology. There are two branches of literature that the book focuses on. It begins with a short introduction to game theory and evolutionary game theory. It then turns to working using signaling games to explore questions related to communication, meaning, language, and reference. The second part of the book addresses prosociality - strategic behavior that contributes (...) to the successful functioning of social groups - using the prisoner's dilemma, stag hunt, and bargaining games.

Recently, game theory and evolutionary game theory - mathematical frameworks from economics and biology designed to model and explain interactive behavior - have proved fruitful tools for philosophers in areas such as ethics, philosophy of language, social epistemology, and political philosophy. This methodological osmosis is part of a trend where philosophers have blurred disciplinary lines to import the best epistemic tools available. In this vein, experimental philosophers have drawn on practices from the social sciences, and especially from psychology, to expand (...) philosophy's grasp on issues from morality to consciousness. We argue that the recent prevalence of formal work on human interaction in philosophy opens the door for new methods in experimental philosophy. In particular, we discuss methods from experimental economics, focusing on a small literature we have been developing investigating signaling and communication in humans. We describe results from a novel experiment showing how environmental structure can shape signaling behavior. (shrink)

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.

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 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)

The COVID-19 pandemic created enormously difficult decisions for individuals trying to navigate both the risks of the pandemic and the demands of everyday life. Good decision making in such scenarios can have life and death consequences. For this reason, it is important to understand what drives risk assessments during a pandemic, and to investigate the ways that these assessments might deviate from ideal risk assessments. In a preregistered online study of U.S. residents (N = 841) using two blocks of vignettes (...) about potential COVID exposure scenarios, we investigated the effects of moral judgment, importance, and intentionality on COVID infection risk assessments. Results demonstrate that risk judgments are sensitive to factors unrelated to the objective risks of infection. Specifically, activities that are morally justified are perceived as safer while those that might subject people to blame or culpability, are seen as riskier, even when holding objective risk fixed. Similarly, unintentional COVID exposures are judged as safer than intentional COVID exposures. While the effect sizes are small, these findings may have implications for public health and risk communications, particularly if public health officials are themselves subject to these biases.

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

Scientists are generally subject to social pressures, including pressures to conform with others in their communities, that affect achievement of their epistemic goals. Here we analyze a network epistemology model in which agents, all else being equal, prefer to take actions that conform with those of their neighbors. This preference for conformity interacts with the agents’ beliefs about which of two possible actions yields the better result. We find a range of possible outcomes, including stable polarization in belief and action. (...) The model results are sensitive to network structure. In general, though, conformity has a negative effect on a community’s ability to reach accurate consensus about the world. (shrink)

The study of intellectual humility (IH), which is gaining increasing interest among cognitive scientists, has been dominated by a focus on individuals. We propose that IH operates at the collective level as the tendency of a collective’s members to attend to each other’s intellectual limitations and the limitations of their collective cognitive efforts. Given people’s propensity to better recognize others’ limitations than their own, IH may be more readily achievable in collectives than individuals. We describe the socio-cognitive dynamics that can (...) interfere with collective IH and offer the solution of building intellectually humbling environments that create a culture of IH that can outlast the given membership of a collective. We conclude with promising research directions. (shrink)

In their recent book, Oreskes and Conway ([ 2010 ]) 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 (i) promoting and sharing independent research supporting the industry’s preferred position and (ii) 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. 1Introduction 2Epistemic Network Models 3Selective Sharing 4Biased Production 5Journalists as Unwitting Propagandists 6Conclusion Appendix.

According to Grice's `Cooperative Principle', human communicators are involved in a cooperative endeavor. The speaker attempts to make herself understood and the listener, in turn, assumes that the speaker is trying to maximize the ease and effectiveness of communication. While pragmatists recognize that people do not always behave in such a way, the Cooperative Principle is generally assumed to hold. However, it is often the case that the interests of speakers and listeners diverge, at least to some degree. Communication can (...) arise in such situations when the cost of signaling is high enough that it aligns the interests of speaker and listener, but what happens when the cost of signaling is not sufficient to align the interests of those communicating? In these cases the theoretical prediction is that they will reach a partially informative system of communication. Using methods from experimental economics, we test whether theoretical predictions are borne out. We find that subjects do learn to communicate without the cooperative principle. (shrink)

The aim of the present study was to investigate the effect of the “Visual Awareness Education Programme” developed to support the visual literacy skills of preschool children. The study group comprised 40 children (20 children in the experimental group and 20 children in the control group) attending preschool in the 2014–2015 school year. The pre-test post-test experimental model was used in the study. The “Visual Literacy Inventory for Preschool Children” and the “Children’s Visual Literacy Rating Inventory for Parents” were used (...) to determine visual literacy level of children. Study results revealed significant differences in favour of the experimental group children in the sub-dimensions and the post-test scores of the “Visual Literacy Inventory for Preschool Children” and the post-test scores of the “Children’s Visual Literacy Rating Inventory for Parents”.

The IHME Covid-19 prediction model has been one of the most influential Covid models in the United States. Early on, it received heavy criticism for understating the extent of the epidemic. I argue that this criticism was based on a misunderstanding of the model. The model was best interpreted not as attempting to forecast the actual course of the epidemic. Rather, it was attempting to make a conditional projection: telling us how the epidemic would unfold, given certain assumptions. This misunderstanding (...) of the IHME’s model prevented the public from seeing how dire the model’s projections actually were. (shrink)

The period from Kant to Hegel is one of the most intense and rigorous in modern philosophy. The central problem at the heart of it was the development of a new standard of theoretical reflection and of the principle of rationality itself. The essays in this volume, published in 2000, consider both the development of Kant's system of transcendental idealism in the three Critiques, the Metaphysical Foundations of Natural Science, and the Opus Postumum, as well as the reception and transformation (...) of that idealism in the work of Fichte, Schelling and Hegel.

Health professionals do not always have the luxury of making “right” choices. This article introduces the “devil's choice” as a metaphor to describe medical choices that arise in circumstances where all the available options are both unwanted and perverse. Using the devil's choice, the paper criticizes the principle of double effect and provides a re-interpretation of the conventional legal and ethical account of symptom relief in palliative care.

In _Opposition to Philosophy in Safavid Iran_ Ata Anzali and S.M. Hadi Gerami offer a critical edition of what is arguably the most erudite and extensive critique of philosophy from the Safavid period. The editors’ extensive introduction offers an in-depth analysis that places the work within the broader framework of Safavid intellectual and social history.

This is a comment to Graham Harman’s 2019 response to an article by Þóra Pétursdóttir and Bjørnar Olsen (2018) in which they propose that a materially grounded, archaeological perspective might complement Harman’s historical approach in Immaterialism (2016). Harman responds that his book is indeed already more archaeological than historical, stipulating that history is the study of media with a high density of information, whereas archaeology studies media with a low density of information. History, Harman holds, ends up in too much (...) detail, while archaeology has the advantage of lending itself to the imagination. Hence, his reading of history had the aim of tempering the historical information overload, in effect making the book a work of archaeology. In this comment, I want to do three things: (1) critique the idea that archaeological and historical media are inherently different with regard to their densities of information, (2) discuss how archaeology and history approach their media, and (3) reflect on conceptualisations of “archaeology” outside the discipline itself.

The introduction of the Diagnostic and statistical manual of mental disorders in May 2013 is being hailed as the biggest event in psychiatry in the last 10 years. In this paper I examine three important issues that arise from the new manual: Expanding nosology: Psychiatry has again broadened its nosology to include human experiences not previously under its purview . Consequence-based ethical concerns about this expansion are addressed, along with conceptual concerns about a confusion of “construct validity” and “conceptual validity” (...) and a failure to distinguish between “disorder” and “non disordered conditions for which we help people.” The role of claims about societal impact in changes in nosology: Several changes in the DSM-5 involved claims about societal impact in their rationales. This is due in part to a new online open comment period during DSM development. Examples include advancement of science, greater access to treatment, greater public awareness of condition, loss of identify or harm to those with removed disorders, stigmatization, offensiveness, etc. I identify and evaluate four importantly distinct ways in which claims about societal impact might operate in DSM development. Categorisation nosology to spectrum nosology: The move to “degrees of severity” of mental disorders, a major change for DSM-5, raises concerns about conceptual clarity and uniformity concerning what it means to have a severe form of a disorder, and ethical concerns about communication.

Yaffe's handling of two general questions is assessed in this review. The first question is why mere attempts (as opposed to successful wrongdoing) should be made punishable in a well-conceived criminal code. The second question is how attempt liability should be conceived in such a code. As to the first question, Yaffe's nonsubstantive mode of answering it (in terms of his ) is contrasted to answers based on some more substantive desert-bases; Yaffe's own more substantive kind of answer (in terms (...) of a desert-base of ) is examined in light of the implication that the traditional requirements of trying and intending are mere proxies for faulty reason recognition and response as the basis for blaming and punishing attempts. As to the second question, Yaffe's analysis of trying in terms of a is examined in some detail. Canvassed here are the subquestions of: (1) whether appropriate assessibility by certain norms of rationality can give the nature of intending and thus of trying; (2) whether the externally de dicto intent requirements of criminal law statutes can easily be interpreted and applied by standard, extensional methods; (3) whether the distinctions between various kinds of elements within the content of intentions, can be justified ontologically or only practically; (4) whether actors necessarily intend results of their actions that are to other results that clearly are intended, and if not, whether such actors are nonetheless just as blameworthy for those results as if they did intend them; and (5) whether intention with respect to circumstance-elements differ (in either their psychology or in their moral effect) from beliefs with respect to such circumstance-elements.

Unlike his other fictional works Blanchot’s 1953 narrative Celui qui ne m’accompagnait pas has received comparatively little attention. The reasons for this would seem to lie in the intense abstraction of his writing in this work, which is forbidding even by his own standards, but as I will show, this intensity can be understood as comprising a singular topography of the experience of writing. Blanchot’s narrative thereby becomes a very precise and concrete form of aesthetics, which can be usefully compared (...) to the understandings of melancholy developed by Benjamin and Adorno, but transposed into a more stringent modernist context.

On the theory of meaning and reference (semantics) as interpretated by W.V. Quine; a study.

In C.Q. N.S. vii , 164 ff. Professor Demos raises the question in what sense, if at all, the state which Plato describes in the Republic can be regarded as ideal, if the warrior-class and the masses are ‘deprived of reason’ and therefore imperfect. The ideal state, he thinks, appears at first sight to be composed of un-ideal individuals. But ‘the problem is resolved by separating the personal from the political-technical areas of control. In so far as they are citizens, (...) men in the ideal city will indeed represent one part of the soul and one function.…. (shrink)
