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.

Non-Invasive Prenatal Testing is a technology which provides information about fetal genetic characteristics very early in pregnancy by examining fetal DNA obtained from a sample of maternal blood. NIPT is a morally complex technology that has advanced quickly to market with a strong push from industry developers, leaving many areas of uncertainty still to be resolved, and creating a strong need for health policy that reflects women’s social and ethical values. We approach the need for ethical policy-making by studying the (...) use of NIPT and emerging policy in the province of Ontario, Canada. Using an adapted version of constructivist grounded theory, we conducted interviews with 38 women who have had personal experiences with NIPT. We used an iterative process of data collection and analysis and a staged coding strategy to conduct a descriptive analysis of ethics issues identified implicitly and explicitly by women who have been affected by this technology. The findings of this paper focus on current ethical issues for women seeking NIPT, including place in the prenatal pathway, health care provider counselling about the test, industry influence on the diffusion of NIPT, consequences of availability of test results. Other issues gain relevance in the context of future policy decisions regarding NIPT, including funding of NIPT and principles that may govern the expansion of the scope of NIPT. These findings are not an exhaustive list of all the potential ethical issues related to NIPT, but rather a representation of the issues which concern women who have personal experience with this test. Women who have had personal experience with NIPT have concerns and priorities which sometimes contrast dramatically with the theoretical ethics literature. These findings suggest the importance of engaging patients in ethical deliberation about morally complex technologies, and point to the need for more deliberative patient engagement work in this area.

_Wittgenstein, Mind and Meaning_ offers a provocative re-reading of Wittgenstein's later writings on language and mind, and explores the tensions between Wittgenstein's ideas and contemporary cognitivist conceptions of the mental. This book addresses both Wittgenstein's later works as well as contemporary issues in philosophy of mind. It provides fresh insight into the later Wittgenstein and raises vital questions about the foundations of cognitivism and its wider implications for psychology and cognitive science.

There are clear associations between the overall quantity of input children are exposed to and their vocabulary acquisition. However, by uncovering specific features of the input that matter, we can better understand the mechanisms involved in vocabulary learning. We examine whether exposure to wh-questions, a challenging quality of the communicative input, is associated with toddlers' vocabulary and later verbal reasoning skills in a sample of low-income, African-American fathers and their 24-month-old children. Dyads were videotaped in free play sessions at home. (...) Videotapes were transcribed and reliably coded for sheer quantity of fathers' input as well as the number of wh-questions fathers produce. Children's productive vocabulary was measured at 24 months using the McArthur Bates Communicative Development Inventory MCDI, and children's verbal reasoning skills were measured 1 year later using the Bayley Scales of Infant Development. Results indicate that the overall quantity of father talk did not relate to children's vocabulary or reasoning skills. However, fathers' use of wh-questions related to both vocabulary and reasoning outcomes. Children's responses to wh-questions were more frequent and more syntactically complex, measured using the mean length of utterance, than their responses to other questions. Thus, posing wh-questions to 2-year-olds is a challenging type of input, which elicits a verbal response from the child that likely helps build vocabulary and foster verbal reasoning abilities.

Communication is an important component in the construction of workplace identities, including leader and group identities. Micro-level analysis of everyday workplace discourse provides valuable insights into the way leadership is constructed and how workplace culture is created, maintained, and changed. In this context, leaders and managers are inevitably significant and influential participants, with a crucial impact on workplace culture. Drawing on audio and video data collected in 12 meetings of an IT department, the analysis demonstrates ways in which two leaders, (...) who succeed each other in the role of Director, reinforce and shape the culture of the workplace in which they operate. While both leaders claim teamwork as an important cultural value for their teams, their respective instantiations of teamwork are rather different. To explore the leaders' effect on the culture of their department, this investigation of leadership change examines ways in which the leaders manage regular workplace meetings and how they contribute to workplace humour. The analysis provides detailed evidence of the ways in which a change in leadership style can create the conditions for a change in the culture of a community of practice. (shrink)

Doig, Meredith The promise from new Victorian Premier, Daniel Andrews, to make Victoria the 'education state' is welcome and timely.

Psychological essentialism is the belief that some internal, unseen essence or force determines the common outward appearances and behaviors of category members. We investigated whether reasoning about transplants of bodily elements showed evidence of essentialist thinking. Both Americans and Indians endorsed the possibility of transplants conferring donors' personality, behavior, and luck on recipients, consistent with essentialism. Respondents also endorsed essentialist effects even when denying that transplants would change a recipient's category membership (e.g., predicting that a recipient of a pig's heart (...) would act more pig-like but denying that the recipient would become a pig). This finding runs counter to predictions from the strongest version of the “minimalist” position (Strevens,2000), an alternative to essentialism. Finally, studies asking about a broader range of donor-to-recipient transfers indicated that Indians essentialized more types of transfers than Americans, but neither sample essentialized monetary transfer. This suggests that results from bodily transplant conditions reflect genuine essentialism rather than broader magical thinking. (shrink)

Despite great advances in understanding genetic mechanisms, there still exists a bias toward equating genes with innate modules that determine important developmental events. But genes are equally relevant to understanding developmental plasticity shaped by ecological events. In other words, the term 'genetic inheritance' does not specify ontogenetic mechanisms. Here we present a case history of a species assumed to be under the control of prespecified genetic wiring to direct critical behavioral events such as communication and mating. We show, however, that (...) exogenetic processes stemming from the species's ontogenetic niche provide an alternative view of the flexibility of development especially with respect to behavioral performance.

There is considerable debate amongst philosophers as to the basic philosophical problem Wittgenstein is attempting to solve in _Philosophical Investigations_. In this bold and original work, Meredith Williams argues that it is the problem of "normative similarity". In _Blind Obedience_ Williams demonstrates how Wittgenstein criticizes traditional, representationalist theories of language by employing the ‘master/novice’ distinction of the learner, arguing that this distinction is often overlooked but fundamental to understanding philosophical problems about mind and language. The book not only provides (...) revealing discussions of Wittgenstein’s corpus but also intricate analyses of the work of Brandom, Dummett, Frege, Sellars, Davidson, Cavell and others. These are usefully compared in a bid to better situate Wittgenstein’s non-intellectualist, non-theoretical approach and to highlight is unique features. (shrink)

A review of the literature on corporate governance serves to demonstrate the applicability of many governance solutions to the university setting. Based on a review of university scandals, most of which are recent but some of which took place decades ago, it is possible to categorize them as follows: sex scandals, drugs, cheating, hazing, admissions and diplomas, on-the-job consumption, athletics, and murder. Several examples are provided in the paper, along with their impact on various stakeholders. The paper then discusses a (...) variety of solutions designed to either preempt the activities potentially leading to scandal, to deter them or to punish perpetrators. Some of these involve structural changes, institutional policies and procedures, fines, terminations, and sanctions. The paper emphasizes the proactive safeguards which govern and monitor to make sure that universities do not suffer on the back end and that their reputations do not suffer into the future. (shrink)

Exploring an aesthetics of complexity relevant to contemporary art, the artist/author discusses the 56th Venice Biennale, curated by Okwui Enwezor, in light of Philip Galanter’s essay ‘Complexism and the role of evolutionary art’. Artworks by Steve McQueen, Isaac Julien, Mika Rottenberg, Hito Steyerl, Im Heung-Soon, Katrīna Neiburga and Andris Eglītis are related to concepts of emergence, chaos, feedback, generative process, and networks, and writings by philosopher Manuel Delanda, sociologist Saskia Sassen and physicist James P. Crutchfield. As one of the most (...) influential international exhibitions of contemporary art, the Venice Biennale is considered a bellwether of future trends; this edition called ‘All the World’s Futures’ presents artwork in context with a dissolving binary paradigm of communism/capitalism that fails to adequately address labour, environmental and immigration issues. The author concludes that an approach informed by complexity theory holds more promise, aesthetically and politically. (shrink)

In this article we provide a case history of the development of a communicative system in songbirds. In particular, we explore how brown-headed cowbirds, male and female, cooperate in the development and use of species-typical song. The goal is to show how social interactions between and within sexes create a platform for the production and perception of song. We consider six perspectives. First, we discuss the nature of the acoustic signal. Second, we look at the process of song learning. Third, (...) we describe a specific song mechanism, social shaping. Fourth, we look at the more general developmental process of neophenogenesis. Fifth, we consider the developmental ecology for social learning. Finally, we describe how social networks measures can be used to capture the nature of social interactions as the engines of song learning. Taken as a whole, we argue that culturally transmitted behaviors structure social interactions that predict the acquisition of species' typical behaviors necessary for successful reproduction.

This book addresses how Plato, Kant, and Iris Murdoch view the connection aesthetic experience has to morality. While offering an examination of Iris Murdoch’s philosophy, it analyses deeply the suggestive links between Plato’s and Kant’s philosophies. Meredith Trexler Drees considers not only Iris Murdoch’s concept of unselfing, but also its relationship with Kant’s view of Achtung and Plato’s view of Eros. In addition, Trexler Drees suggests an extended, and partially amended, version of Murdoch’s view, arguing that it is more (...) compatible with a religious way of life than Murdoch herself realized. This leads to an expansion of the overall argument to include Kant’s affirmation of religion as an area of life that can be improved through Plato’s and Murdoch’s vision of how being good and being beautiful can be part of the same life-task.

A classic problem in cognitive science concerns how listeners perceive and understand speech as comprised of discrete words. We propose a Syllable Inference account of spoken word recognition and segmentation, under which alternative hierarchical models of syllables, words, and phonemes are dynamically posited from cues that include current and past speech rate, with a goal of maximal prediction of sensory input. Three experiments using the Visual World eye‐tracking paradigm provide evidence supporting our proposal.

The micro-regional focus of bioregionalism is a small unit of physical space, typically a watershed region. In bioregional discourse, natural systems become metaphors for cultural coherence. However, when we look for laws embedded in the natural world, those that are found do not then reveal themselves as principles which apply to systems of culture. Further, within most individuals, the sense of regional identity spans several scales because our past narratives and present affiliations span several localities. Humans are not immersed in (...) singular niches, nor is the bioregionalist an existential, primordial localist, for his or her choice has been crafted. (shrink)

Nineteenth-century optical toys that showcase illusions of motion such as the phenakistoscope, zoetrope, and praxinoscope, have enjoyed active “afterlives” in the twentieth and twenty-first centuries. Contemporary incarnations of the zoetrope are frequently found in the realms of fine art and advertising, and they are often much larger than their nineteenth-century counterparts. This article argues that modern-day optical toys are able to conjure feelings of wonder and spectacle equivalent to their nineteenth-century antecedents because of their adjustment in scale. Exploring a range (...) of contemporary philosophical toys found in arts, entertainment, and advertising contexts, the article discusses various technical adjustments made to successfully “scale up” optical toys, including the replacement of hand-spun mechanisms with larger sources of motion and the use of various means such as architectural features and stroboscopic lights to replace traditional shutter mechanisms such as the zoetrope’s dark slots. Critical consideration of scale as a central feature of these installations reconfigures the relationship between audience and device. Large-scale adaptations of optical toys revise the traditional conception of the user, who is able to tactilely manipulate and interact with the apparatus, instead positing a viewer who has less control over the illusion’s operation and is instead a captive audience surrounded by the animation. It is primarily through their adaptation of scale that contemporary zoetropes successfully elicit wonder as scientific spectacles from their audiences today. (shrink)

What's not to like about shared decision‐making? These programs employ specially crafted decision aids to educate patients about their treatment options and then merge the newly informed patient preferences, both general and treatment‐specific, with guidance from physicians to optimize medical decisions. Sounds great, right? Even better, recent evidence indicates that shared decision‐making programs may also help bend the proverbial cost curve by reducing the use of medical interventions that patients, now properly educated about their options, often say they do not (...) want. The notion that programs to inform and elicit patient choice might also help to align health care delivery with patient preferences for less invasive and therefore less costly treatment options seems the rarest of mutual wins in health care, in which what is best for the individual might also benefit the whole. Yet there has been scant attention to how the goals of patient care and cost‐containment, and perhaps even profitability, coincide or conflict. (shrink)

I discuss Peter Singer’s claim that the interests of animals merit equal consideration with those of human beings. I show that there are morally relevant differences between humans and animals that Singer’s rather narrow utilitarian conception of morality fails to capture. Further, I argue that Singer’s formal conception of moral equality is so thin as to be virtually vacuous and that his attempts to give it moresubstance point to just the kind of differences between humans and animals that undermine his (...) equalitarian thesis.

The problem of how we can be both animals living in a causal world and agents acting through norms, principles, and rules in that same world persists. Many have understood this as a clash between science and our ordinary ways of talking. For many, this clash has been resolved in favour of the scientific image, either by reducing the intentional and normative to the causal laws of behaviourism or by eliminating our 'folk psychology' altogether in favour of a syntactic or (...) computational model of mind. Drawing on Wittgenstein, I argue that this mislocates the problem and so misunderstands what is required for its resolution. Our sophisticated language games are grounded in a bedrock of normative similarity judgments. The role these play in our language games can be seen most clearly in the initiate learning situation, that of the child just learning language or the pupil receiving first instruction in arithmetic. It is here that we can look for an accommodation of causality and normativity by understanding the relation between the novice and the master of the practice. (shrink)

Discussions of both personal responsibility and the importance of trust in health-care settings are increasingly prominent in the bioethics literature. In this paper I link the two discussions and argue that health policies that include personal responsibility ought to address climates of social trust. Trust is a social good that is not always fairly distributed. Disadvantaged social groups often face default distrust. I suggest that agent-centered models in which responsibilities are negotiated do a better job of repairing social distrust than (...) authoritative models in which responsibilities are assigned. Attending to climates of trust, distrust, or antitrust is essential for addressing health inequalities. (shrink)
