The late Fifties were going to be eventful for physics in Italy. CERN had officially started its activities in the fall of 1954; however, the single European countries, Italy in the first place, were not in the condition to compete at the highest international level. A peculiar form of international distribution of the forms of research activities was then going to characterize those years, in particular as far as relationships between Italy and the United States were concerned. Italian physicists who (...) had become known in the United States and were in close relationship with their colleagues active on the opposite shore of the Atlantic obtained that the analysis of data collected in American labs.---in particular bubble chamber data---could be partially carried out in Italy. I try here to give a feeling of the kind of theoretical activity that involved Franco Selleri, among others, in that context. (shrink)

Recent conversation has blurred two very different social epistemic phenomena: echo chambers and epistemic bubbles. Members of epistemic bubbles merely lack exposure to relevant information and arguments. Members of echo chambers, on the other hand, have been brought to systematically distrust all outside sources. In epistemic bubbles, other voices are not heard; in echo chambers, other voices are actively undermined. It is crucial to keep these phenomena distinct. First, echo chambers can explain the post-truth phenomena in a way that epistemic (...) bubbles cannot. Second, each type of structure requires a distinct intervention. Mere exposure to evidence can shatter an epistemic bubble, but may actually reinforce an echo chamber. Finally, echo chambers are much harder to escape. Once in their grip, an agent may act with epistemic virtue, but social context will pervert those actions. Escape from an echo chamber may require a radical rebooting of one's belief system.

This article explores what John Dewey’s political philosophy can offer in regard to the current crisis in digital democracy. It focuses on two digital mechanisms, the “filter bubble” and the “echo chamber”. While there is a prominent, Dewey-inspired debate on “digital publics” in the literature, a reconstruction of the Deweyan concepts of the public and of shared experience shows that it does not adequately reflect the aspect of situated and embodied experience. Based on this, it is shown that (...) digital media offerings must also be rooted in local contexts of experience in order to answer the challenge of those two problematic mechanisms. (shrink)

It is often claimed that epistemic bubbles and echo chambers foster post-truth by filtering our access to information and manipulating our epistemic attitude. In this paper, I try to add a further level of analysis by adding the issue of belief formation. Building on cognitive psychology work, I argue for a dual-system theory according to which beliefs derive from a default system and a critical system. One produces beliefs in a quasi-automatic, effortless way, the other in a slow, effortful way. (...) I also argue that digital socio-epistemic environments tend to inculcate disvalues in their agent's epistemic identity, a process that causes the cognitive shortcircuits typical of conspiracy theories.

This paper aims to reflect on the anthropological nature of the digital infosphere being contextual for phenomena such as epistemic bubbles and echo chambers. Is the digital infosphere, the general context for phenomena such as epistemic bubbles and echo chambers, an anthropological place or a non-place? The answer to this question is important to better understand the issue, and to learn how to approach it in a good enough way to minimize the potential harms such as successful disinformation campaigns and (...) occasions of hate speech.

It is widely believed that we are facing a problem, even a crisis, caused by so-called “echo chambers” and “filter bubbles.” Here, David Coady argues that this belief is mistaken. There is no such problem, and we should refrain from using these neologisms altogether. They serve no useful purpose, since there is nothing we can say with them that we cannot say equally well or better without them. Furthermore, they cause a variety of harms, including, ironically, a tendency to narrow (...) public debate within predetermined limits. (shrink)

This article is an exercise in the virtue epistemology of the internet, an area of applied virtue epistemology that investigates how online environments impact the development of intellectual virtues, and how intellectual virtues manifest within online environments. I examine online echo chambers and epistemic bubbles (Nguyen 2020, Episteme 17(2), 141–61), exploring the conceptual relationship between these online environments and the virtue of open-mindedness (Battaly 2018b, Episteme 15(3), 261–82). The article answers two key individual-level, virtue epistemic questions: (Q1) How does immersion (...) in online echo chambers and epistemic bubbles affect the cultivation and preservation of open-mindedness, and (Q2) Is it always intellectually virtuous to exhibit open-mindedness in the context of online echo chambers and epistemic bubbles? In response to Q1, I contend that both online echo chambers and online epistemic bubbles threaten to undermine the cultivation and preservation of open-mindedness, albeit via different mechanisms and to different degrees. In response to Q2, I affirm that both a deficiency and an excess of open-mindedness can be virtuous in these online environments, depending on the epistemic orientation of the digital user. (shrink)

In Neal Stephenson’s fictional novel, Diamond Age (1995), the protagonist Nell acquires a prototype of what we might today recognise as a highly sophisticated e-reader with a voice-assistant. This e-reader, the “Young Lady’s Illustrated Primer”, uses artificial intelli- gence to serve as Nell’s personal teacher. What is key to the Primer is how it is designed to respond to Nell. The Primer has a theory of Nell – her needs, her real-world situation, her abilities – and it tailors its lessons (...) for her. The Primer is a highly personalised artificially intelligent device. For many readers – myself included – the Primer was a utopian vision of the bespoke digital tutors of the future. The appearance of new media and technologies in the early 2000s all pointed to the near-term reality of devices like Primers. The real-life experience of personalised digital media, though, is so far from Stephen- son’s vision that it is hard to imagine we will ever get there. Nell’s time with the Primer develops her intellectually, emotionally, and physically. Our “bespoke” media experience, by contrast, is more likely to turn us in on ourselves rather than guide us to live well in our societies. Personalised media is making us more like Narcissus: our consumption is driven by personal choices and automated algorithms that reflect what we already want to hear, see, and consume, and we are captivated. Central to our understanding of the problems with the personalisation of digital media are filter bubbles and echo chambers. These phenomena are used interchangeably by some, but in distinct ways by others. I take the position that filter bubbles and echo chambers are distinct phenomena, but ones that raise similar epistemic worries. I begin with a general discussion of filter bubbles and echo chambers, and I introduce the concept of “selective exposure” as central to both phenomena. There is minimal uniformity across uses of the terms “filter bubble” and “echo chamber”. Consequently, I divide the later discussion into two more precise topics: homophily and polarisation. I conclude with some future-looking comments about responsibility and the epistemic risks posed by digital personalisation. (shrink)

It's a bold but frankly risky opening shot for Kaebnick, Gusmano, and Murray to commence their report by claiming that a “majority opinion” or a “near‐con­sensus” has now been reached on the matter of synthetic biology. Risky because “majority opinions,” even in well‐established controversies, are highly unstable (events will have many surprises in store) but also risky because... well... the majority of whom, exactly? North American bioethicists? Invitees to Washington roundtable discus­sions? Or some sort of broader meaningful public major­ity? According (...) to the authors, the particular unspecified majority they have in mind agrees that a social contract of sorts has already been hammered out in which “society should allow the technology to proceed and even provide it some financial support.”Has the burgeoning debate over synthetic biology re­ally already come to a gentleman's agreement brokered roughly along terms described by the U.S. President's Commission for the Study of Bioethical Issues in its re­port of 2011? I don't think so. (shrink)

In this paper, I argue that considerations of epistemic bubbles can give us reason to defend censorship of hate speech. Although censoring hate speech leads to epistemic bubbles (‘censorship bubbles’), they tend to be less epistemically problematic than epistemic bubbles generated by the circulation of hate speech (‘hate bubbles’). Because hate speech silences its target groups and creates the illusion that the dominant group identities are threatened, hate bubbles are likely more restrictive in structure than censorship bubbles and have a (...) stronger tendency to turn into echo chambers where opposing views are actively discredited. Therefore, I argue that censorship bubbles might be a minor price we ought to pay to avoid hate bubbles. Additionally, my analysis shows that we cannot focus exclusively on the content or the structure of epistemic bubbles, since their content can partly determine their structure, as is in the case of hate bubbles.

Intellectual interest in epistemic bubbles and echo chambers has grown exponentially over the past two decades. This is largely because many assume, in light of recent events, that these phenomena are morally, socially, politically, and epistemically problematic. But are we justified in simply assuming that epistemic bubbles and echo chambers are inherently epistemically problematic? Perhaps surprisingly, numerous philosophers have recently argued that epistemic bubbles and echo chambers are not intrinsically epistemically problematic. Nevertheless, I argue, this trend is mistaken. Epistemic bubbles (...) and echo chambers are all intrinsically epistemically problematic, such that we should try to escape them, if we find ourselves in them. Crucially, there are two senses in which we might identify epistemic bubbles and echo chambers as being intrinsically epistemically problematic, as opposed to “good.” After distinguishing between these senses, I demonstrate that, even if there is a sense in which epistemic bubbles can in principle be “good,” all epistemic bubbles are epistemically problematic in the sense that is ultimately relevant to the question of whether we ought to stay in epistemic bubbles or to try to get out of them.

In this paper, we will re-elaborate the notions of filter bubble and of echo chamber by considering human cognitive systems’ limitations in everyday interactions and how they experience digital technologies. Researchers who applied the concept of filter bubble and echo chambers in empirical investigations see them as forms of algorithmically-caused systems that seclude the users of digital technologies from viewpoints and opinions that oppose theirs. However, a significant majority of empirical research has shown that users do find (...) and interact with opposing views. Furthermore, we argue that the notion of filter bubble overestimates the social impact of digital technologies in explaining social and political developments without considering the not-only-technological circumstances of online behavior and interaction. This provides us with motivation to reconsider this notion’s validity and re-elaborate it in light of existing epistemological theories that deal with the discomfort people experience when dealing with what they do not know. Therefore, we will survey a series of philosophical reflections regarding the epistemic limitations of human cognitive systems. In particular, we will discuss how knowledge and mere belief are phenomenologically indistinguishable and how people’s experience of having their beliefs challenged is cause of epistemic discomfort. We will then go on to argue, in contrast with Pariser’s assumptions, that digital media users might tend to conform to their held viewpoints because of the “immediate” way they experience opposing viewpoints. Since online people experience others and their viewpoints as material features of digital environments, we maintain that this modality of confronting oneself with contrasting opinions prompts users to reinforce their preexisting beliefs and attitudes.

Recent work in social epistemology has drawn attention to various problematic social epistemic phenomena that are common within online networks. Nguyen (2020) argues that it is important to distinguish epistemic bubbles from echo chambers. An epistemic bubble is an information structure that merely lacks information or sources that would be relevant or important to the user. An echo chamber is a structure in which dissenting opinions are, not necessarily absent, but actively undermined, for example by instilling attitudes of (...) distrust towards their adherents. Because of this, echo chambers are thought to be especially difficult to escape. In contrast, according to Nguyen, it is relatively easy to shatter an epistemic bubble: one simply introduces the missing information. In this paper, I argue that it is more difficult to shatter an epistemic bubble than has been recognised in the literature. The reason for this is the relationship between epistemic bubbles and interpretative resources. Despite their epistemic drawbacks, it is comparatively easy to gain knowledge from sources inside one's epistemic bubble because agents within a bubble share common ground. In contrast, it can be very difficult to gain knowledge from sources outside of one's bubble because interlocutors on the outside are less likely to have the shared context needed to facilitate communicative success. I argue that this problem suggests a different way to understand the nature of epistemic bubbles and our prospects for escaping them. (shrink)

The aim of the paper is to analyze the formation and the main traits of new communica­tive spaces in the form of “epistemic echo-bubbles” and “echo-cameras”. Their emer­gence is associated with a transdisciplinary type of scientific revolution. Among the re­sults of this revolution is the Internet and various social networks. Their popularity among different strata of the population makes these networks are not just mass phenom­ena, but effective tools for communication and influence on the views spread in society and shared (...) by many individuals. The mechanisms of “epistemic echo-bubbles” and “echo-chambers” are explored and described. The fundamental differences in their func­tioning are emphasized, namely, that “epistemic echo-bubbles” are formed due to the similarity of people’s views (in the broad sense of life, including political life), and the emotions accompanying these views, so that subjects with different views and emo­tions are simply “not heard” within the boundaries of the echo-bubbles. Echo-chambers are understood to be actually closed communicative spaces formed by bringing together people with similar views (in the broad sense of life, including political life) and emo­tions accompanying these views. Subjects with different views are deliberately not al­lowed into these spaces, their views are discredited and “exposed” by special methods and techniques. Echo chambers are built on the rigid principle of distinguishing “friend” from “foe”, exercising rigid epistemic control over the state of minds and forming special structures of countering and exposing the authoritative opinions of opposition representa­tives. Examples of “echo-bubbles” and “echo-chambers” from modern political life (mainly in the USA) are given. The genesis of “echo-bubbles” and “echo-chambers” is associated with the phenomenon of post-truth and the transformation of language, which began to occur around the middle of the 19th century and which consists of an increase in the specific age of emotive components and a tendency to shift interest from collective action to individual activity.

The US populace appears to be increasingly polarized on partisan lines. Political fissures bifurcate the country even on empirical matters like vaccine safety and anthropogenic climate change. There now exists an ever-expanding interdisciplinary research program in which theorists attempt to explain increases in political polarization and myriad other phenomena collected under the “post-truth” heading by appeal to social-epistemic structures, like echo chambers and epistemic bubbles, that affect the flow and uptake of information in various communities. In this paper, I critically (...) analyze C. Thi Nguyen’s important and popular analysis of echo chambers and epistemic bubbles. As I demonstrate, the explanatory mechanisms on which Nguyen focuses are, arguably, overly cognitive and obscure significant effects of social-epistemic structures on our affective lives. The broader lesson to draw from my discussion is the following: commonly used expressions intended to refer to social-epistemic problems, like “political polarization”, possess no univocal definition across theorists, and various ways of making the terms precise are differentially successful in characterizing verifiable phenomena. Theorizing about social-epistemic structures should be responsive to relevant empirical work on various phenomena that we have good reason to believe constitute real and substantive problems that result from the flow and uptake of information.

Following Cass Sunstein's popular treatment of the concept, echo chambers are often defined as environments which exclude contrary opinions through omission. C. Thi Nguyen contests the popular usage and defines echo chambers in terms of in-group trust and out-group distrust. In this paper, I argue for a more comprehensive treatment. While both exclusion by omission and out-group distrust help sustain echo chambers, neither defines the phenomenon. I develop a social network model of echo chambers which focuses on the role of (...) belief-reinforcing echoes. First, I argue that the model allows us to incorporate Nguyen's main point about distrust without construing other commentators as deeply mistaken about the nature of echo chambers. Second, I use the model to develop an account of collaborative resistance and use it to clarify the role echo chambers play in spreading misinformation. (shrink)

This article discusses the topic of algorithmic personalization and the creation of the so-called “filter bubble” effect, which is often understood as one of the most problematic influences of artificial intelligence on democratic social order. The author suggests that focusing on the issue of information diversity, which had far-reaching effect on the empirical research that tried to quantitatively measure and systematically prove the existence of the filter bubbles, was the wrong starting point for the discussion on the application of (...) algorithmic personalization. It has drawn our attention away from the deeper issue: habit. Habitual adaptation of algorithmic personalization, namely, stands in essential contradiction to the ideal image of a non-adaptive public sphere, upon which democratic societies should be based. Focusing on habitual adaptation could also explain why users addictively stick to certain kinds of information, even if they are not caught in an isolated chamber. (shrink)

The extensive use of digital platforms has presented considerable challenges to democracy, particularly in the realms of politics and ideology in Brazil. The emergence of digital echo chambers and the rise of extreme viewpoints pose threats to social cohesion, informed decision-making, and the development of individual identities. This analysis focuses specifically on identity formation, the creation and dissemination of information, emphasizing its repercussions on social identity and cultural diversity. Consequently, the influence of these echo chambers in promoting extremist views in (...) this context is just one facet of the broader ideological, racial, and class polarization facing the nation. To face these challenges, it is imperative to defend critical and reflective education on the role and use of social networks, both in the educational system and in the daily lives of young people and society.

Are the members of echo chambers blameworthy for their beliefs? If we follow Sarah Stroud's account of friendship, we end up with the following conclusion: if echo chambers involve friendship, then the individuals have strong reasons not to live up to epistemic demands or ideals when the friendships are formed in the echo chambers they are members of. This result stands in striking contrast with the received view, according to which the members of echo chambers are blameworthy for their epistemic (...) vices and faulty beliefs. The received view uses individual epistemic vices to propose individualistic solutions for the problem of echo chambers. I argue that this is misleading, simply because the members of echo chambers are not blameworthy due to the friendships cultivated in the echo chambers. (shrink)

In a cloud chamber, the quantum measurement problem amounts to explaining the first droplet in a charged-particle track; subsequent droplets are explained by Mott’s 1929 wave-theoretic argument about collision-induced wavefunction collimation. I formulate a mechanism for how the first droplet in a cloud chamber track arises, making no reference to quantum measurement axioms. I look specifically at tracks of charged particles emitted in the simplest slow decays, because I can reason about rather than guess the form that wave (...) packets take. The first visible droplet occurs when a randomly occurring, barely-subcritical vapor droplet is pushed past criticality by ionization triggered by the faint wavefunction of the emitted charged particle. This is possible because potential energy incurred when an ionized vapor molecule polarizes the other molecules in a droplet can balance the excitation energy needed for the emitted charged particle to create the ion in the first place. This degeneracy is a singular condition for Coulombic scattering, leading to infinite or near-infinite ionization cross sections, and from there to an emergent Born rule in position space, but not an operator projection as in the projection postulate. Analogous mechanisms may explain canonical quantum measurement behavior in detectors such as ionization chambers, proportional counters, photomultiplier tubes or bubble chambers. This work is important because attempts to understand canonical quantum measurement behavior and its limitations have become urgent in view of worldwide investment in quantum computing and in searches for super-rare processes.

Some common explanations of issue polarization and echo chambers rely on social or cognitive mechanisms of exclusion. Accordingly, suggested interventions like “be more open-minded” target these mechanisms: avoid epistemic bubbles and don’t discount contrary information. Contrary to such explanations, we show how a much weaker mechanism—the preference for belief—can produce issue polarization in epistemic communities with little to no mechanisms of exclusion. We present a network model that demonstrates how a dynamic interaction between the preference for belief and common structures (...) of epistemic communities can turn very small unequal distributions of initial beliefs into full-blown polarization. This points to a different class of explanations, one that emphasizes the importance of the initial spread of information. We also show how our model complements extant explanations by including a version of biased assimilation and motivated reasoning—cognitive mechanisms of exclusion. We find that mechanisms of exclusion can exacerbate issue polarization, but may not be the ultimate root of it. Hence, the recommended interventions suggested by extant literature is expected to be limited and the problem of issue polarization to be even more intractable. (shrink)

In this article, I argue that online echo chambers are in some cases and in some respects good. I do not attempt to refute arguments that they are harmful, but I argue that they are sometimes beneficial. In the first section, I argue that it is sometimes good to be insulated from views with which one disagrees. In the second section, I argue that the software-design principles that give rise to online echo chambers have a lot to recommend them. Further, (...) the opposing principle, serendipity, could give rise to serious harm, in light of the conclusion of the first section that sometimes we are better off being insulated from some content online. In the third section, I argue that polarization can be a useful tool for inculcating the appropriate attitudes in a person. (shrink)

This ambitious book by one of the most original and provocative thinkers in science studies offers a sophisticated new understanding of the nature of scientific, mathematical, and engineering practice and the production of scientific knowledge. Andrew Pickering offers a new approach to the unpredictable nature of change in science, taking into account the extraordinary number of factors—social, technological, conceptual, and natural—that interact to affect the creation of scientific knowledge. In his view, machines, instruments, facts, theories, conceptual and mathematical structures, disciplined (...) practices, and human beings are in constantly shifting relationships with one another—"mangled" together in unforeseeable ways that are shaped by the contingencies of culture, time, and place. Situating material as well as human agency in their larger cultural context, Pickering uses case studies to show how this picture of the open, changeable nature of science advances a richer understanding of scientific work both past and present. Pickering examines in detail the building of the bubble chamber in particle physics, the search for the quark, the construction of the quarternion system in mathematics, and the introduction of computer-controlled machine tools in industry. He uses these examples to address the most basic elements of scientific practice—the development of experimental apparatus, the production of facts, the development of theory, and the interrelation of machines and social organization.

Recently, there has been growing concern that increased partisanship in news sources, as well as new ways in which people acquire information, has led to a proliferation of epistemic bubbles and echo chambers: in the former, one tends to acquire information from a limited range of sources, ones that generally support the kinds of beliefs that one already has, while the latter function in the same way, but possess the additional characteristic that certain beliefs are actively reinforced. Here I argue, (...) first, that we should conceive of epistemic bubbles and echo chambers as types of epistemically pernicious groups, and second, that while analyses of such groups have typically focused on relationships between individual members, at least part of what such groups epistemically pernicious pertains to the way that members rely on the groups themselves as sources of information. I argue that member reliance on groups results in groups being attributed a degree of credibility that outruns their warrant, a process I call groupstrapping. I argue that by recognizing the groupstrapping as an illicit method of forming and updating beliefs we can make progress on some of the open questions concerning epistemically pernicious groups.

In this study I aim to develop a cognitive evaluation of how semantically-driven and rule-based diagrammatic reasoning were psychologically plausible for partic-ular cases of scientific practice: an actual trackless path reconstruction in bubble chamber experiments, as reported by Galison (1997). I will propose “cognitive imagery projection and manipulation” (CIPM) as the most plausible psychologi-cal (perceptual/attentional/cognitive) mechanism matching the specific explanatory requirements for the case study, outlining the most significant current theories about this mental phenomenon (Shimojima; 2011).

One reason that fake news and other objectionable views gain traction is that they often come to us in the form of testimony from those in our immediate social circles – from those we trust. A language around this phenomenon has developed which describes social epistemic structures in terms of ‘epistemic bubbles’ and ‘epistemic echo chambers’. These concepts involve the exclusion of external evidence in various ways. While these concepts help us see the ways that evidence is socially filtered, it (...) doesn’t help us understand the social functions that these structures play, which limits our ability to intervene on them. In this paper, I introduce a new concept – that of the epistemic bunker. This concept helps us better account for a central feature of the phenomenon, which is that exclusionary social epistemic structures are often constructed to offer their members safety, either actual or perceived. Recognising this allows us to develop better strategies to mitigate their negative effects. (shrink)

In this paper I explore Phyllis Rooney’s 2003 chapter, “Feminist Epistemology and Naturalized Epistemology: An Uneasy Alliance,” taking guidance from her critique of naturalized epistemology in pursuing my own analysis of another uneasy alliance: that between feminist epistemology and social epistemology. Investigating some of the background assumptions at work in prominent conceptions of social epistemology, I consider recent analyses of "epistemic bubbles" to ask how closely such analyses are aligned with ongoing research in feminist epistemology. I argue that critical feminist (...) insights in political philosophy are called for here, especially those that focus on multiple politically salient relationships and also emphasize practices of personal transformation as inseparably bound up with broader movements for social transformation. Insofar as feminist epistemology continues to carry another world in its heart, I argue that it will continue to rest uneasily with any effort to align it with—let alone subsume it within—the still emerging field of social epistemology.

The main question addressed in this essay is whether quarks have been observed in any sense and, if so, what might be meant by this use of the term, observation. In the first (or introductory) section of the paper, I explain that well-known researchers are divided on the answers to these important questions. In the second section, I investigate microphysical observation in general. Here I argue that Wilson's analogy between observation by means of high-energy accelerators and observation by means of (...) microscopes is misleading, for at least three reasons. Moreover, so long as high-energy observation is accomplished by means of spark or bubble chambers, then sentences about these observations do not meet Maxwell's criterion, that observation statements are quickly decidable. I argue, however, that this criterion is not a good norm for what is observable in high-energy physics, both because it would result in our describing a great many allegedly observed particle events as unobserved or theoretical, and because it fails to distinguish the reasons why some observation statements might not be quickly decidable. Most important, Maxwell's criterion fails because, contrary to Hanson's analysis, it presupposes that seeing does not involve both seeing as and seeing that.With this background concerning what is meant by general microphysical observation, in the third section of the essay, I discuss what might be meant by a more particular type of observation, that of the quark via scattering events. I employ Feinberg's distinction concerning observation of manifest, versus existent, particles and claim that the alleged indirect observation of quarks as existent particles is really based on a retroductive inference. I explain which premise in the retroductive argument appears most open to the charge of being theoretical (in a damaging sense) and less substantiated by observation. (shrink)

According to our understanding of the everyday physical world, observable phenomena are underpinned by persistent objects that can be reidentified across time by observation of their distinctive properties. This understanding is reflected in classical mechanics, which posits that matter consists of persistent, reidentifiable particles. However, the mathematical symmetrization procedures used to describe identical particles within the quantum formalism have led to the widespread belief that identical quantum particles lack either persistence or reidentifiability. However, it has proved difficult to reconcile these (...) assertions with the fact that identical particles are routinely assumed to be reidentifiable in particular circumstances. For example, when two electrons move through a bubble chamber, each is said to generate a sequence of bubbles that is caused by one and the same particle. Moreover, neither of these assertions accounts for the mathematical form of the symmetrization procedures used to describe identical particles within the quantum framework, leaving open theoretical possibilities other than bosonic and fermionic behavior, such as paraparticles, which do not appear to be realized in nature. Here we propose the novel idea that both persistence and nonpersistence models must be employed in order to fully account for the behaviour of identical particles. Thus, identical particles are neither persistent nor nonpersistent. We prove the viability of this viewpoint by showing how Feynman's and Dirac's symmetrization procedures arise through a synthesis of a quantum treatment of these models, and by showing how reidentifiability emerges in a context-dependent manner. We further show that the persistence and nonpersistence models satisfy the key characteristics of Bohr's concept of complementarity, and thereby propose that the behavior of identical particles is a manifestation of a persistence-nonpersistence complementarity, analogous to Bohr's wave-particle complementarity for individual particles. Finally, we construct a precise parallel between these two complementarities, and detail their conceptual similarities and dissimilarities. (shrink)

In their responses to my article “Epistemically Pernicious Groups and the Groupstrapping Problem” (Boyd, 2018), Bert Baumgaertner (“Groupstrapping, Boostrapping, and Oops-strapping: A Reply to Boyd”) and C. Thi Nguyen (“Group-strapping, Bubble, or Echo Chamber?”) have raised interesting questions and opened lines of inquiry regarding my discussion of what I hope to be a way to help make sense of how members of groups can continue to hold beliefs that are greatly outweighed by countervailing evidence (e.g. antivaxxers, climate-change deniers, (...) etc.). Here I respond to these arguments and suggestions by providing three new reasons to believe that groupstrapping as I describe it occurs in epistemically pernicious groups. (shrink)

A stalwart view in the philosophy of science holds that, even when broadly construed so as to include theoretical auxiliaries, theories cannot make direct contact with observations. This view owes much to Bogen and Woodward’s influential distinction between data and phenomena. According to them, data are typically the kind of things that are observable or measurable like "bubble chamber photographs, patterns of discharge in electronic particle detectors and records of reaction times and error rates in various psychological experiments". (...) Phenomena are physical processes that are typically unobservable. Examples of the latter category include "weak neutral currents, the decay of the proton, and chunking and recency effects in human memory". Theories, in Bogen and Woodward’s view, are utilised to systematically explain, infer and predict phenomena, not data. The relationship between theories and data is rather indirect. Data count as evidence for phenomena and the latter in turn count as evidence for theories. This view is becoming increasingly influential, Stathis Psillos and Mauricio Suárez ). In this paper I argue contrary to this view that in various significant and well-known cases theories do make direct contact with the help of suitable auxiliaries. (shrink)

The contemporary proliferation of “filter bubbles” and “echo chambers” seems to render obsolete the notion of a public sphere in the singular. In my article, I would like to argue against this view: Following Jürgen Habermas, “the public sphere” can be understood as the concomitant horizon of communicative action, while the latter permeates society as a whole. On the basis of this socio-philosophical approach, the omnipresent tendencies toward fragmentation appear as reactive attempts to ward off this socially established and context-transcending (...) context of discussion. Habermas himself, however, has never adopted this perspective. Instead, he interprets the various symptoms of the decline of the public sphere—including its fragmentation—as the result of a “colonization of the lifeworld” by economic, bureaucratic, and technological system logics. However, on the basis of the concept of “systematically distorted communication,” which was still crucial for Habermas’s early work, it is possible to reconstruct how the lifeworld context of communicative action, out of which the public sphere emerges, is not only corroded and cut through from the outside by system logics but also exhibits its own dialectic of the refusal of discourse and the overcoming of this refusal. The fragmentation of the public sphere that we are confronted with today can be theoretically interpreted and politically addressed as a precarious standstill of this dialectic. (shrink)

Underestimated for a long time, serendipity is an increasingly recognized design principle of the infosphere. Being influenced by environmental and human factors, the experience of serendipity encompasses fundamental phases of production, distribution and consumption of information. On the one hand, design information architectures for serendipity increases the diversity of information encountered as well as users’ control over information processes. On the other hand, serendipity is a capability. It helps individuals to internalize and adopt strategies that increase the chances of experiencing (...) it. As such, the pursuit for serendipity can help to burst filter bubbles and weaken echo chambers in social media. The article reviews the literature on emerging issues surrounding serendipity in human–computer interactions. By doing so, it firstly presents the study of serendipity and the debate about its role in digital environments. Then, it introduces the main features of a preliminary architecture for serendipity. Finally, it analyzes from an interdisciplinary perspective the values that embraces and sustains. The conclusion is that serendipity can be conceived as an emerging design and ethical principle able to strengthen media pluralism and other emerging human rights in the context of online personalization. Main limitations and potential unintended consequences are also discussed. (shrink)

De modo a explicar o sucesso das realizações científicas, as abordagens tradicionais em filosofia da ciência empregam critérios epistemológicos; abordagens socioconstrutivistas, a) também utilizam critérios epistemológicos, porém o fazem sem o rigor das abordagens tradicionais, b) quando empregam conceitos socioconstrutivistas, eles não são tão bem definidos quanto os critérios epistemológicos, e c) investem muito mais em narrativas do que propriamente em reconstruções conceituais.

It is commonly agreed that so-called echo chambers and epistemic bubbles, associated with social media, are detrimental to liberal democracies. Drawing on John Rawls’s political liberalism, we offer a novel explanation of why social media platforms amplifying echo chambers and epistemic bubbles are likely contributing to the violation of the democratic norms connected to the ideal of public reason. These norms are clarified with reference to the method of (full) reflective equilibrium, which we argue should be cultivated as a civic (...) virtue in the context of political justification. The paper demonstrates how epistemic bubbles and echo chambers are likely to be detrimental to the disposition to follow the method of reflective equilibrium in the political context. Based on this diagnosis the paper highlights the need for interventions that help cultivate reflective equilibrium as a civic virtue and the need for corresponding interdisciplinary research.

Social epistemologists should be well-equipped to explain and evaluate the growing vulnerabilities associated with filter bubbles, echo chambers, and group polarization in social media. However, almost all social epistemology has been built for social contexts that involve merely a speaker-hearer dyad. Filter bubbles, echo chambers, and group polarization all presuppose much larger and more complex network structures. In this paper, we lay the groundwork for a properly social epistemology that gives the role and structure of networks their due. In particular, (...) we formally define epistemic constructs that quantify the structural epistemic position of each node within an interconnected network. We argue for the epistemic value of a structure that we call the (m,k)-observer. We then present empirical evidence that (m,k)-observers are rare in social media discussions of controversial topics, which suggests that people suffer from serious problems of epistemic vulnerability. We conclude by arguing that social epistemologists and computer scientists should work together to develop minimal interventions that improve the structure of epistemic networks. (shrink)

Using the Aristotelian virtue of friendship and concept of practical wisdom, this paper argues that engaging in political discourse with friends on social media is conducive to the pursuit of the good life because it facilitates the acquisition of the socio-political information and understanding necessary to live well. Previous work on social media, the virtues, and friendship focuses on the initiation and maintenance of the highest form of friendship (Aristotle’s ‘ideal friendship’) online. I argue that the information necessary to live (...) well can come from non-ideal, civic friends in addition to ideal friends. In order to acquire this information successfully via social media, users should practice inclusive engagement, self-control, discretion, and audience-sensitivity in their cyber interactions. This argument is salient given the current concerns about ‘echo chambers’ or ‘filter bubbles’, in which users ignore or block out friends and news sources that support political perspectives different from one’s own.

Conspiracy theories are spreading faster than ever and pose a real danger to our societies. It is natural to accuse the consumers of conspiracy theories of irrationality – that they are either not looking at or appropriately sensitive to all the available evidence. In this paper, I attempt to determine if we can make sense of this general idea. I argue that we cannot: conspiracy theories do not spread because the people who believe them are irrational – at least, not (...) necessarily so. In addition, I explore some alternative strategies for responding to the problem of the spread of conspiracy theories. I argue that in addition to confrontational strategies such as social shaming, we need more constructive programs of community activism to battle the spread of conspiracy theories. (shrink)

We start by introducing the idea of echo chambers. Echo chambers are social and epistemic structures in which opinions, leanings, or beliefs about certain topics are amplified and reinforced due to repeated interactions within a closed system; that is, within a system that has a rather homogeneous sample of sources or people, which all share the same attitudes towards the topics in question. Echo chambers are a particularly dangerous phenomena because they prevent the critical assessment of sources and contents, thus (...) leading the people living within them to deliberately ignore or exclude opposing views. In the second part of this paper, we argue that the reason for the appearance of echo chambers lies in the adoption of what we call ‘epistemic vices’. We examine which vices might be responsible for their emergence, and in doing so, we focus on a specific one; ‘epistemic violence’. In assessing and evaluating the role of this epistemic vice, we note that it can be triggered by epistemic contexts characterized by high stakes that may turn ordinary intellectual virtues (such as skepticism) into vices (such as denialism). In the third part of this contribution, we suggest a way to deal with echo chambers. The solution focuses on advocating a responsibilist pedagogy of virtues and vices that -we claim- might be capable of preventing their emergence. (shrink)

This Second Edition of A New Environmental Ethics: The Next Millennium for Life on Earth offers clear, powerful, and often moving thoughts from Holmes Rolston III, one of the first and most respected philosophers to write on the environment and often called the "father of environmental ethics." Rolston surveys the full spectrum of approaches in the field of environmental ethics and offers critical assessments of contemporary academic accounts. He draws on a lifetime of research and experience to suggest an outlook, (...) and even hope, for the future. This forward-looking analysis, focused on the new millennium, will be a necessary complement to any balanced textbook or anthology in environmental ethics. The First Edition guaranteed "to put you in your place." Beyond that, the Second Edition, asks whether you want to live a "de-natured life on a de-natured planet." Key Updates in the Second Edition - Covers the worsening environmental situation due to actions of the Trump administration, including withdrawal from the Paris accord and from the U.N. Framework Convention on Climate Change - Includes information on legislation in key U.S. states aimed to ameliorate the damage done at the Federal level - Increases coverage of group knowledge, group agreement and disagreement, and group action in collective environmental ethics, as distinguished from individual knowledge and action - Examines the deleterious effects of online consumer behavior - Explains how a loss of solidarity among a nation's citizens and even a larger solidary among humanity leads to environmental degradation - Offers new analysis of the effects of epistemic bubbles, echo chambers, and fake news on the behavior of voters and consumers - Provides an extended critique of the Anthropocene Epoch, and the prospect of geo-engineering Earth to become a synthetic environment.

The internet has become an ubiquitous epistemic source. However, it comes with several drawbacks. For instance, the world wide web seems to foster filter bubbles and echo chambers and includes search results that promote bias and spread misinformation. Richard Heersmink suggests online intellectual virtues to combat these epistemically detrimental effects . These are general epistemic virtues applied to the online environment based on our background knowledge of this online environment. I argue that these online intellectual virtues also demand a particular (...) view of cognitive integration. Online intellectual virtues are incompatible with a popular conception of extended minds proposed by Andy Clark and David Chalmers . I suggest that if we want to hold on to both a conception of online intellectual virtues and some conception of the extended mind, we have to accept a more gradual theory of cognitive integration along the lines of second-wave theories of the extended mind.

An increasingly popular solution to the anti-scientific climate rising on social media platforms has been the appeal to more critical thinking from the user's side. In this paper, we zoom in on the ideal of critical thinking and unpack it in order to see, specifically, whether it can provide enough epistemic agency so that users endowed with it can break free from enclosed communities on social media (so called epistemic bubbles). We criticise some assumptions embedded in the ideal of critical (...) thinking online and, instead, we propose that a better way to understand the virtuous behaviour at hand is as critical engagement, namely a mutual cultivation of critical skills among the members of an epistemic bubble. This mutual cultivation allows members within an epistemic bubble (in contrast, as we will show, with the authority-based models of epistemic echo chambers) to become more autonomous critical thinkers by cultivating self-trust. We use the model of relational autonomy as well as resources from work on epistemic self-trust and epistemic interdependence to develop an explanatory framework, which in turn may ground rules for identifying and creating virtuous epistemic bubbles within the environments of social media platforms.

The current political climate is awash with groups that we might be tempted to label irrational, extremist, hyper-partisan; it is full of echo-chambers, radicalization, and epistemic bubbles. Philosophers have profitably analyzed some of these phenomena. In this essay, I draw attention to a crucial but neglected aspect of our time: the way in which certain groups are fanatical. I distinguish fanatical groups from other types of problematic groups, such as extremist and cultish groups. I argue that a group qualifies as (...) fanatical only if it has features that promote individual fanaticism. But how might a group promote individual fanaticism? I argue that a typical feature of fanatical groups is their tendency to encourage an emotion that philosophers sometimes call “ressentiment,” which differs from ordinary resentment. I explain what ressentiment is, how it can be fostered, and how it can lead to fanaticism. I contend that this account helps us to identify a disturbing and increasingly widespread feature of contemporary social and political groups. (shrink)

When membership of a community depends on commitment to shared beliefs, the community is a belief-based coalition, and the beliefs are identity-defining beliefs. Belief-based coalitions are pervasive features of human social life and routinely drive motivated cognition and epistemically dysfunctional group dynamics. Despite this, they remain surprisingly undertheorized in social epistemology. This article (i) clarifies the properties of belief-based coalitions and identity-defining beliefs, (ii) explains why they often incentivize and coordinate epistemically dysfunctional forms of communication and cognitive labor, and (iii) (...) argues that they provide a better explanation of many epistemic problems on social media than the concepts of epistemic bubbles, echo chambers, and gamification.

This thesis is a collection of three self-contained papers on related themes in the area of formal and social epistemology. The first paper explores the possibility of measuring the coherence of a set with multiplicative averaging. It has been pointed out that all the existing probabilistic measures of coherence are flawed for taking the relevance between a set of propositions as the primary factor which determines the coherence of the set. What I show in this paper is that a group (...) of measures, namely the confirmation-based ones, can be saved from this problem if we adopt a nonlinear averaging function to measure the coherence of a set. The second paper discusses how people should conciliate in disagreements. Some epistemologists take linear averaging as the only way of conciliating and claim that conciliating leads to fallacious results. In the paper, I show that the problem is not conciliating, but taking linear averaging as the only way to conciliate. Since there is no reason for us to insist on conciliating with linear averaging, we can adopt nonlinear averaging functions for conciliating and thereby avoid the formal deficiencies. The third paper focuses on the pragmatic results of taking conciliating as a general strategy in disagreements. There is a potential dilemma about conciliating: if everyone always conciliates, it is likely for an epistemic bubble to arise. If everyone refuses to conciliate, an epistemic echo chamber may appear. A possible way of solving the dilemma is to develop a diachronic strategy which tells people how to both conciliate and update their estimate of their interlocutors’ reliability. Although the three papers differ in the subject, they jointly offer some unifying reflections on the way we approach philosophical problems with formal tools. From 5 the first two papers, we see that a formal analysis of a philosophical position is incomplete if philosophers fail to consider a sufficiently wide range of formal tools. The third paper, on the contrary, shows that we should change the ordinary way of modelling a notion if required. This thesis concludes by proposing a pluralistic view of formal methods in formal epistemology. (shrink)

Histories of communication are still relatively rare birds, but this one is distinctive on several grounds. The two authors are/were undisputed giants in the field. Ken Cmiel, the originator of the book, still unfinished when he suddenly died in 2006, was a cultural historian of communication; his best friend, John Peters, is one of the world leaders in the intellectual history of communication. In completing that unfinished manuscript, Peters has performed astonishing prestidigitation here in creating an effective hybrid: he retains (...) the core of Cmiel's account, while creating a unique book that, courtesy of Peters, brilliantly spins out the solid Cmielian core and its material traces into gorgeous reflections on aspects of how we make our way through a world of images and information. Promiscuous Knowledge constructs a cultural and intellectual history of information, images, and conceptions of knowledge since the 17th century, with an emphasis on the American context since the 19th century. Cmiel/Peters sketch the way in which various containers for information-knowledge, expertise, abridgment, books, digests, encyclopedias, museums, etc.-have variably organized gluts of information, and how these containers have eroded since the 1970s. A parallel throughline traces social attitudes and practices around images and key media for circulating and experiencing them. Cmiel envisioned the largest contour of the book as a contribution to the history of truth and truth-making. His protagonists are pictures and facts, images and information. They enact a process of gradual dismantling, erosion, or collapse of the mass culture system from last century into the present. Promiscuous knowledge has a new face, courtesy of the online universe full of filter bubbles, echo chambers, and fake news. Google offers a single portal to a churning mass of confusion; it lacks a principle of inclusion/inclusivity, it has no way of framing the whole. Peters has shaped what Cmiel started out with into a better Trump-era book than an Obama-era book. And he has retained its core: a brief history of how we left the world of fact for the world of information. (shrink)
