Much like the trade and traits of bubbles in financial markets, similar bubbles appear on the science market. When economic bubbles burst, the drop in prices causes the crash of unsustainable investments leading to an investor confidence crisis possibly followed by a financial panic. But when bubbles appear in science, truth and reliability are the first victims. This paper explores how fashions in research funding and research management may turn science into something like a bubble economy.

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.

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)

An epic project in both size and purview, Peter Sloterdijk's three-volume, 2,500-page Spheres is the late-twentieth-century bookend to Heidegger's Being and Time. Rejecting the century's predominant philosophical focus on temporality, Sloterdijk, a self-described "student of the air," reinterprets the history of Western metaphysics as an inherently spatial and immunological project, from the discovery of self to the exploration of world to the poetics of plurality. Exploring macro- and micro-space from the Greek agora to the contemporary urban apartment, Sloterdijk is able (...) to synthesize, with immense erudition, the spatial theories of Aristotle, René Descartes, Gaston Bachelard, Walter Benjamin, and Georges Bataille into a morphology of shared, or multipolar, dwelling--identifying the question of being as one bound up with the aerial technology of architectonics and anthropogenesis.Sloterdijk describes Bubbles, the first volume of Spheres, as a general theory of the structures that allow couplings--or as the book's original intended subtitle put it, an "archeology of the intimate." Bubbles includes a wide array of images, not to illustrate Sloterdijk's discourse, but to offer a spatial and visual "parallel narrative" to his exploration of bubbles.Written over the course of a decade, the Spheres trilogy has waited another decade for its much-anticipated English translation from Semiotext.

Social media have undoubtedly changed our ways of living. Their presence concerns an increasing number of users (over 4,74 billion) and pervasively expands in the most diverse areas of human life. Marketing, education, news, data, and sociality are just a few of the many areas in which social media play now a central role. Recently, some attention toward the link between social media and political participation has emerged. Works in the field of artificial intelligence have already pointed out that there (...) is a close link between the use of machine learning algorithms in social media and possible epistemic isolation, which could lead to political radicalization. The idea supporting this paper is that artificial intelligence for social media can actively put users’ deliberative capacity at risk and foster political extremism. To prove these claims, I proceed along two lines of inquiry. First, I focus on filter bubbles, namely the result of selections made by algorithms that recommend contents that meet users’ expectations and opinions. To analyze this phenomenon, I refer to the Deweyan model of experience. Second, I connect the filter bubbles problem to the Deweyan idea of deliberative and participatory democracy and Nussbaum’s concept of political compassion. The purpose of this paper is to provide a philosophical foundation that can both (1) effectively serve as a method for analyzing machine learning algorithms and their potential problems in relation to political extremism, and (2) be adopted as a standard to counter the danger of extremism associated with social media experience.

A time series of the Shanghai stock index in China for the 1990s is studied for the possible existence of nonlinear speculative bubbles. Three alternative specifications of fundamentals are estimated using VAR models of domestic and international variables. These are subjected to regime switching tests and rescaled range analysis tests. Nulls of no persistence were mostly rejected, suggesting the strong possibility of bubbles. Nonlinearities beyond ARCH effects using the BDS test could not be rejected. The paper also discusses (...) the special circumstances of the stock market in an emerging transition economy. (shrink)

ABSTRACTA Danish fitness chain recently introduced a new concept called Bubbles & Squat. Here, fitness training is combined with free champagne and music. In this paper, we examine this new way of bringing parties, alcohol and physical culture together by exploring the possible meaning of it through existential philosophical analysis. We draw in particular on Nietzsche’s distinction between the Apolline and the Dionysiac, as well as his account of great health. On this basis, we analyse Bubbles & Squat (...) as a case of Dionysiac intoxication, excess and ecstasy sneaking into contemporary Apolline fitness culture. In the last part of the paper, we raise the question if adding parties and bubbles to fitness training may, perhaps paradoxically, be healthy for the participants in an existential sense because it contributes to existential balance between the Dionysiac and the Apolline. We conclude that the philosophical framework presented in this paper can contribute to a new understanding of a general physical c... (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.

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)

The purpose of this paper is to analyze the financial turmoil of the US subprime loan crisis of mid-Noughties and to compare it with the Japanese asset bubble of late 1980s. While examining the two crises, it compares the monetary policies of both countries, focusing on the excess liquidity and expansion of bank loans that were seen. This paper develops several bubble indicators, including the ratio of real estate loans to total loans, the loan-to-GDP ratio, and housing affordability. In order (...) to develop these indicators, it is necessary to compare banking behavior in both Japan and the United States, as banks in both countries were making loans beyond the point of profit maximization. Property prices and monetary policy in both countries influenced banking behavior significantly. The bubble indicators developed in this paper can be used as early warning indicators for future bubbles. (shrink)

Lehar (rightly) insists on the volumetric character of our experience of space. He claims that three-dimensional space stems from the functional three-dimensional topology of the brain. But his “Gestalt Bubble” model of volumetric space bears an intrinsically static structure – a kind of theater, or “diorama,” bound to the visual modality. We call attention to the ambivalence of Gestalt legacy and question the status and precise import of Lehar's model and the phenomenology that motivates it.

In this paper, we argue that boredom can be an important experience that contributes to personal autonomous agency by providing authentic motivation, and that strategies of social media providers to bind users’ attention to their platforms undermine this authenticity. As discussed in social epistemology and media ethics for a while now, such strategies can lead to so-called epistemic or filter bubbles. Our analysis of the relation between boredom and social media use focuses on a similarly impairing effect of social (...) media on users’ autonomy, which we call authenticity bubbles. (shrink)

Lehar misrepresents the Neuron Doctrine and indirect realism. His conclusions on consciousness are unjustified. The Bubble Gestalt perceptual modeling disconnected from neuroscience has no explanatory power.

Speculative bubbles present a problem for the development of sophisticated financial markets in developing economies. This paper discusses the evolution of regulatory institutions in Pakistan pertaining to the Karachi stock exchange and empirically tests for the presence of stock market bubbles in that stock market in recent years. A fundamental is estimated using a VAR approach, and residuals of this fundamental are tested for trends using Hamilton regime switching and Hurst rescaled range methods. Nonlinearities beyond ARCH are also (...) tested for using the BDS test. We are unable to reject the hypothesis of no bubbles or non nonlinearities during the period studied, indicating that Pakistan faces this difficult problem in developing appropriate regulations and institutions for the oversight of its financial markets.

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)

It is commonly assumed that personalization technologies used by Google for the purpose of tailoring search results for individual users create filter bubbles, which reinforce users’ political views. Surprisingly, empirical evidence for a personalization-induced filter bubble has not been forthcoming. Here, we investigate whether filter bubbles may result instead from a searcher’s choice of search queries. In the first experiment, participants rated the left-right leaning of 48 queries (search strings), 6 for each of 8 topics (abortion, benefits, climate (...) change, sex equality, immigration, nuclear family, Islam, and taxation). An independent sample of participants were then asked to select one of these queries for each of the 8 topics. With the exception of the topic of Islam, participants were significantly more likely to select a query corresponding to their own political leaning, compared to other queries, explaining between 12% and 39% of the variance. A second experiment investigated the effect of the political leaning of the same queries on the overall political leaning of Search Engine Result Pages (SERPs) in Google Search. The top six results of each SERP were rated collectively by a third group of participants, explaining 36.3% of the variance across all 48 search terms (p < .00001). That is, (1) participants in our experiments tended to select own-side search queries, and (2) using those queries tended to yield own-side search results when using the Google search engine. Our results are consistent with the notion of a self-imposed filter bubble in which query selection plays a salient role. (shrink)

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)

It is common to allocate scarce health care resources by maximizing QALYs per dollar. This approach has been attacked by disability-rights advocates, policy-makers, and ethicists on the grounds that it unjustly discriminates against the disabled. The main complaint is that the QALY-maximizing approach implies a seemingly unsatisfactory conclusion: other things being equal, we should direct life-saving treatment to the healthy rather than the disabled. This argument pays insufficient attention to the downsides of the potential alternatives. We show that this sort (...) of discrimination is one of four unpalatable consequences that any approach to priority setting in health care must face. We argue that, given the alternatives, it is far from clear that we should revise the QALY-maximizing approach in response to this objection. (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?

Background: The COVID-19 pandemic has changed the way we conduct daily life, as well as sports training and sports competitions. Given the stress produced by COVID-19, and the “bubble” safety measures for the World Sambo Championship, held in Novi Sad, from the 6th to the 8th of November, 2020, athletes might have experienced more stress than athletes normally would in non-pandemic conditions. Therefore, the current study aimed to create a psychological profile of sambo athletes participating in the Sambo World Championship (...) and living in this condition.Methods: One-hundred-fifteen participants took part in the study, completing the Profile of Mood Scale, the Pittsburg Sleep Quality Index, the Perceived Stress Scale, and the Fear of COVID-19 Scale. A mediation model with Fear of COVID-19 predicting both stress level directly and stress level through mood disturbance was hypothesized. Gender differences were evaluated through t-test.Results: The results showed that the sample presented higher levels of stress but no problems in sleeping. In particular, data analysis confirmed an indirect effect of Fear of COVID on Perceived stress through mood disturbance, but did not have a significant impact on the direct effect. Gender differences emerged in the perceived stress level and daytime dysfunction where females scored higher than males for both aspects.Conclusion: The athletes participating to the World Sambo Championship experienced stress levels determined by the mood disturbance produced by the fear of the COVID-19 pandemic. Female athletes were more stressed and showed higher daytime dysfunction. The findings of the current study are useful to understand the psychological profile of the athletes competing in the “bubble” conditions during COVID-19 pandemic. (shrink)

Efforts to combat the COVID-19 crisis brought mountains of legislation and guidance to coerce or encourage people to stay at home and reduce the spread of the virus. During peak lockdown in the United Kingdom regulations defined when people could or could not leave their homes. Meanwhile guidance on social distancing advised people to stay within ‘households’. This paper explores the legislation under lockdowns in the UK from March to October 2020 and the implications for women’s gendered caring roles. The (...) regulations and guidance assumed that households were separate units and ignored the interdependencies which exist between households and between individuals and wider society. The continuing focus in the lockdown regulations has been on households as autonomous, safe, adequate and secure. This overlooks the interdependency of human life, gendered aspects of caring and the inequalities of housing and living conditions, highlighted by feminist scholarship. (shrink)

Insurance law in the eighteenth century is often seen as a perfect illustration of the way commercial law emerged from a relationship between the judges and the merchants, with Lord Mansfield at the centre, drawing on mercantile custom. This view tends to subordinate the role of both the merchants and Parliament. Yet, merchants were involved in shaping the law not just as witnesses and jurors in Mansfield’s court, but also through their promotion of, and opposition to, legislation, and through the (...) ways in which business was conducted and disputes were resolved.

It has been argued that the Internet and social media increase the number of available viewpoints, perspectives, ideas and opinions available, leading to a very diverse pool of information. However, critics have argued that algorithms used by search engines, social networking platforms and other large online intermediaries actually decrease information diversity by forming so-called “filter bubbles”. This may form a serious threat to our democracies. In response to this threat others have developed algorithms and digital tools to combat filter (...) bubbles. This paper first provides examples of different software designs that try to break filter bubbles. Secondly, we show how norms required by two democracy models dominate the tools that are developed to fight the filter bubbles, while norms of other models are completely missing in the tools. The paper in conclusion argues that democracy itself is a contested concept and points to a variety of norms. Designers of diversity enhancing tools must thus be exposed to diverse conceptions of democracy. (shrink)

This article deals with a modern disease of academic science that consists of an enormous increase in the number of scientific publications without a corresponding advance of knowledge. Findings are sliced as thin as salami and submitted to different journals to produce more papers. If we consider academic papers as a kind of scientific ‘currency’ that is backed by gold bullion in the central bank of ‘true’ science, then we are witnessing an article-inflation phenomenon, a scientometric bubble that is most (...) harmful for science and promotes an unethical and antiscientific culture among researchers. The main problem behind the scenes is that the impact factor is used as a proxy for quality. Therefore, not only for convenience, but also based on ethical principles of scientific research, we adhere to the San Francisco Declaration on Research Assessment when it emphasizes “the need to eliminate the use of journal-based metrics in funding, appointment and promotion considerations; and the need to assess research on its own merits rather on the journal in which the research is published”. Our message is mainly addressed to the funding agencies and universities that award tenures or grants and manage research programmes, especially in developing countries. The message is also addressed to well-established scientists who have the power to change things when they participate in committees for grants and jobs. (shrink)

From Plato's eidos, to Descartes' cogito, to Kant's numenon, our understanding of reality has faltered at a seemingly impossible, double-edged, impasse. First, an ontological 'hard problem': If mind and matter are so radically different and separate, how do they ever interact? Second, a related epistemological conundrum: How is it possible for mind to ever know anything about matter--including whether it even exists? Then came Whitehead. By shifting the mind-matter relation from substances interacting in space to complementary phases in process, he (...) offered a way through, or at least around, the Kantian impasse. His panpsychist ontology came hand-in-glove with an epistemology of intersubjectivity: We can know the objective physical world because the actual world is not just physical, and because it necessarily and intimately informs and constitutes our subjective experience. But is this panpsychism or idealism? And how does it avoid the interaction problem that bedevils dualism or the problem of emergence that embarrasses materialism? (shrink)

The “Gestalt Bubble” model of Lehar is not supported by the evidence offered. The author invalidly concludes that spatial properties in experience entail an explicit volumetric spatial representation in the brain. The article also exaggerates the extent to which phenomenology reveals a completely three-dimensional scene in perception.

A wide range of systems appear to perform computation: what common features do they share? I consider three examples, a digital computer, a neural network and an analogue route finding system based on soap-bubbles. The common feature of these systems is that they have autonomous dynamics — their states will change over time without additional external influence. We can take advantage of these dynamics if we understand them well enough to map a problem we want to solve onto them. (...) Programming consists of arranging the starting state of a system so that the effects of the system''s dynamics on some of its variables corresponds to the effects of the equations which describe the problem to be solved on their variables. The measured dynamics of a system, and hence the computation it may be performing, depend on the variables of the system we choose to attend to. Although we cannot determine which are the appropriate variables to measure in a system whose computation basis is unknown to us I go on to discuss how grammatical classifications of computational tasks and symbolic machine reconstruction techniques may allow us to rule out some measurements of a system from contributing to computation of particular tasks. Finally I suggest that these arguments and techniques imply that symbolic descriptions of the computation underlying cognition should be stochastic and that symbols in these descriptions may not be atomic but may have contents in alternative descriptions.

Substantially increased international financial mobility and internal financial reforms in many countries have led to apparently increased volatility of their financial markets. This heightened volatility has sometimes been associated with rapid increases or decreases in asset values that many observers suspect contain elements of speculative bubbles and their associated crashes, not justified by rational expectations of underlying fundamentals. In addition, these possible bubbles may coincide with nonlinear dynamics beyond basic ARCH effects, thus being nonlinear speculative bubbles.

The idea that deep brain stimulation (DBS) induces changes to personality, identity, agency, authenticity, autonomy and self (PIAAAS) is so deeply entrenched within neuroethics discourses that it has become an unchallenged narrative. In this article, we critically assess evidence about putative effects of DBS on PIAAAS. We conducted a literature review of more than 1535 articles to investigate the prevalence of scientific evidence regarding these potential DBS-induced changes. While we observed an increase in the number of publications in theoretical neuroethics (...) that mention putative DBS-induced changes to patients’ postoperative PIAAAS, we found a critical lack of primary empirical studies corroborating these claims. Our findings strongly suggest that the theoretical neuroethics debate on putative effects of DBS relies on very limited empirical evidence and is, instead, reliant on unsubstantiated speculative assumptions probablyin lieuof robust evidence. As such, this may reflect the likelihood of a speculative neuroethics bubble that may need to be deflated. Nevertheless, despite the low number of first-hand primary studies and large number of marginal and single case reports, potential postoperative DBS changes experienced by patients remain a critical ethical concern. We recommend further empirical research in order to enhance theoretical neuroethics work in the area. In particular, we call for the development of better instruments capable of capturing potential postoperative variations of PIAAAS. (shrink)

In a recent no-go theorem [Bong et al., Nature Physics (2020)], we proved that the predictions of unitary quantum mechanics for an extended Wigner’s friend scenario are incompatible with any theory satisfying three metaphysical assumptions, the conjunction of which we call “Local Friendliness”: Absoluteness of Observed Events, Locality and No-Superdeterminism. In this paper (based on an invited talk for the QBism jubilee at the 2019 Växjö conference) I discuss the implications of this theorem for QBism, as seen from the point (...) of view of experimental metaphysics. I argue that the key distinction between QBism and realist interpretations of quantum mechanics is best understood in terms of their adherence to different theories of truth: the pragmatist versus the correspondence theories. I argue that a productive pathway to resolve the measurement problem within a pragmatist view involves taking seriously the perspective of quantum betting agents, even those in what I call a “Wigner bubble”. The notion of reality afforded by QBism, I propose, will correspond to the invariant elements of any theory that has pragmatic value to all rational agents—that is, the elements that are invariant upon changes of agent perspectives. The classical notion of ‘event’ is not among those invariants, even when those events are observed by some agent. Neither are quantum states. Nevertheless, I argue that far from solipsism, a personalist view of quantum states is an expression of its precise opposite: Copernicanism. (shrink)

In this paper I investigate the representation of self-consciousness in the still life tradition in the Netherlands around the time of Descartes’ residence there. I treat the paintings of this tradition as both a phenomenological resource and as a phenomenological undertaking in their own right. I begin with an introductory overview of the still life tradition, with particular attention to semiotic structures characteristic of the vanitas still life. I then focus my analysis on the representation of self-consciousness in this tradition, (...) identifying both a Cartesian mode of representation of self-consciousness but also a counter trend.

The Gestalt Bubble model describes a subjective phenomenal experience (what is seen) without taking into account the extraphenomenal constraints of perceptual experience (why it is seen as it is). If it intends to be an explanatory model, then it has to include either stimulus or neural constraints, or both.

Here, I propose a new hypothesis: sex originated from an archaic gene transfer process among prebiotic bubbles without the prerequisite for reproduction.

This essay argues that the success of «post-truth» is partially connected to the characteristics of the new «hybrid» communication scenario. The author maintains that the current context differs substantially from the _democracy of parties_, which has characterised a part of the 20 th century, as well as from the _democracy of the public_, a notion formulated by Bernard Manin in the mid-1990s. As a matter of fact, the diffusion of the new media has triggered the fragmentation of _the public_ into (...) a plurality of self-referential segments and «bubbles» which are (potentially) not rooted in an intersubjective sphere of communication. Considering the impact of these transformations, the essay proposes the image of a _bubble democracy_ as an alternative to the mainstream interpretations both of the _democracy of parties _and of the _democracy of the public_ and it argues that its main features are the widespread mistrust towards institutions, audience fragmentation and polarisation.
