Such is the criticism commonly passed upon Socrates in our age, which boasts of its positivity much as if a polytheist were to speak with scorn of the negativity of a monotheist, for the polytheist has many gods, the monotheist only one. So our philosophers have many thoughts, all valid to a certain extent; Socrates had only one, which was absolute.

The Hong and Page ‘diversity trumps ability’ result has been used to argue for the more general claim that a diverse set of agents is epistemically superior to a comparable group of experts. Here we extend Hong and Page’s model to landscapes of different degrees of randomness and demonstrate the sensitivity of the ‘diversity trumps ability’ result. This analysis offers a more nuanced picture of how diversity, ability, and expertise may relate. Although models of this sort can indeed be suggestive (...) for diversity policies, we advise against interpreting such results overly broadly. (shrink)

A scientific community can be modeled as a collection of epistemic agents attempting to answer questions, in part by communicating about their hypotheses and results. We can treat the pathways of scientific communication as a network. When we do, it becomes clear that the interaction between the structure of the network and the nature of the question under investigation affects epistemic desiderata, including accuracy and speed to community consensus. Here we build on previous work, both our own and others’, in (...) order to get a firmer grasp on precisely which features of scientific communities interact with which features of scientific questions in order to influence epistemic outcomes.

Polarization is a topic of intense interest among social scientists, but there is significant disagreement regarding the character of the phenomenon and little understanding of underlying mechanics. A first problem, we argue, is that polarization appears in the literature as not one concept but many. In the first part of the article, we distinguish nine phenomena that may be considered polarization, with suggestions of appropriate measures for each. In the second part of the article, we apply this analysis to evaluate (...) the types of polarization generated by the three major families of computational models proposing specific mechanisms of opinion polarization.

We apply spatialized game theory and multi-agent computational modeling as philosophical tools: (1) for assessing the primary social psychological hypothesis regarding prejudice reduction, and (2) for pursuing a deeper understanding of the basic mechanisms of prejudice reduction.

Epistemic justifications for democracy have been offered in terms of two different aspects of decision-making: voting and deliberation, or ‘votes’ and ‘talk.’ The Condorcet Jury Theorem is appealed to as a justification in terms votes, and the Hong-Page “Diversity Trumps Ability” result is appealed to as a justification in terms of deliberation. Both of these, however, are most plausibly construed as models of direct democracy, with full and direct participation across the population. In this paper, we explore how these results (...) hold up if we vary the model so as to reflect the more familiar democratic structure of a representative hierarchy. We first recount extant analytic work that shows that representation inevitably weakens the voting results of the Condorcet Jury Theorem, but we question the ability of that result to shine light on real representative systems. We then show that, when we move from votes to talk, as modeled in Hong-Page, representation holds its own and even has a slight edge. (shrink)

In late January of 1987, the State Treasurer of Pennsylvania, R. Budd Dwyer, shot himself to death in front of a dozen reporters and camera crews during a news conference in his office. Much was subsequently made in the popular press, and within the profession, about the difficult ethical decision television journalists were faced with in determining how much of the very graphic suicide tape to air. A review of the literature in this area suggests, however, that journalists have established (...) a set of relatively detailed conventions for dealing with events involving graphic depictions of death. Analysis of the Dwyer tape and interviews conducted with Pennsylvania television news directors show that eighteen of the twenty stations in the state that carry news used basically the same type and amount of footage in their evening newscasts. One decided to use no tape. One showed the moment of death. When the story broke around noon, two additional stations showed the moment of suicide, but they revised their story for the evening program. In addition, the wide majority of news directors interviewed said they had little difficulty in deciding how to edit the tape. The processing of the Dwyer story suggests that any ethical dilemmas faced by journalists during decision making were put aside for later consideration. The material was edited quickly and according to similar patterns, or conventions, around the state. The study suggests greater attention be given to the definition and interaction of personal professional values, in the ethical sense, and norms of news processing, in the sociological sense.

Equally suitable for undergraduates and specialists in the humanities, this collection provides an in-depth introduction to debates within post-colonial theory and criticism. The readings are drawn from a diverse selection of Third World and Western thinkers, both historical and contemporary. "Post-colonialism" is taken by the editors to include Third World and diasporic experience; like "colonialism," it is understood to contain a complex set of cultural, ethnographic, political, and economic processes and conflicts. This volume explores such issues as the nature of (...) colonized cultures and anti-colonial resistance; subaltern historiography; constructions of Western subjectivity, knowledge, and gender; the formation of post-colonial intellectuals; the metropolitan institutionalization of post-colonialism; neo-colonialism; and the nature of minority and post-colonial identity and discourse. One section is devoted to the application of theoretical formulations to cultural criticism, and contains a number of textual analyses. A general introduction to the volume as well as introductions to each section provide historical, theoretical, and poltical contexts for the readings. The book concludes with an extensive bibliography. (shrink)

ABSTRACT This article distinguishes nine senses of polarization and provides formal measures for each one to refine the methodology used to describe polarization in distributions of attitudes. Each distinct concept is explained through a definition, formal measures, examples, and references. We then apply these measures to GSS data regarding political views, opinions on abortion, and religiosity—topics described as revealing social polarization. Previous breakdowns of polarization include domain-specific assumptions and focus on a subset of the distribution’s features. This has conflated multiple, (...) independent features of attitude distributions. The current work aims to extract the distinct senses of polarization and demonstrate that by becoming clearer on these distinctions we can better focus our efforts on substantive issues in social phenomena.

Robustness has long been recognized as an important parameter for evaluating game-theoretic results, but talk of ‘robustness’ generally remains vague. What we offer here is a graphic measure for a particular kind of robustness (‘matrix robustness’), using a three-dimensional display of the universe of 2 × 2 game theory. In such a measure specific games appear as specific volumes (Prisoner’s Dilemma, Stag Hunt, etc.), allowing a graphic image of the extent of particular game-theoretic effects in terms of those games. The (...) measure also allows for an easy comparison between different effects in terms of matrix robustness. Here we use the measure to compare the robustness of Tit for Tat’s well-known success in spatialized games (Axelrod, R. (1984). The evolution of cooperation . New York: Basic Books; Grim, P. et al. (1998). The philosophical computer: Exploratory essays in philosophical computer modeling . Cambridge, Mass: MIT Press) with the robustness of a recent game-theoretic model of the contact hypothesis regarding prejudice reduction (Grim et al. 2005. Public Affairs Quarterly, 19 , 95–125).

There remains much to be learned from searching exploration of the great authors who have meditated on education. Montaigne is one such thinker and this essay endeavors to draw together the strands of his pedagogy and to demonstrate how they gain purchase in the business of teaching and learning. The article also proposes to supplement his vision with practical examples from fiction and autobiography. Perhaps the most striking theme is the need to be able to decentre from the comfort zone (...) of acquired beliefs and convictions and the crucial role played by conversation in cultivating the intellectual and moral openness in order to do so. At the heart of Montaigne’s writing on education is what can be called a pedagogy of conversation. (shrink)

Public discussions of political and social issues are often characterized by deep and persistent polarization. In social psychology, it’s standard to treat belief polarization as the product of epistemic irrationality. In contrast, we argue that the persistent disagreement that grounds political and social polarization can be produced by epistemically rational agents, when those agents have limited cognitive resources. Using an agent-based model of group deliberation, we show that groups of deliberating agents using coherence-based strategies for managing their limited resources tend (...) to polarize into different subgroups. We argue that using that strategy is epistemically rational for limited agents. So even though group polarization looks like it must be the product of human irrationality, polarization can be the result of fully rational deliberation with natural human limitations. (shrink)

In a series of formal studies and less formal applications, Hong and Page offer a ‘diversity trumps ability’ result on the basis of a computational experiment accompanied by a mathematical theorem as explanatory background (Hong & Page 2004, 2009; Page 2007, 2011). “[W]e find that a random collection of agents drawn from a large set of limited-ability agents typically outperforms a collection of the very best agents from that same set” (2004, p. 16386). The result has been extremely influential as (...) an epistemic justification for diversity policy initiatives. Here we show that the ‘diversity trumps ability’ result is tied to the particular random landscape used in Hong and Page’s simulation. We argue against interpreting results on that random landscape in terms of ‘ability’ or ‘expertise.’ These concepts are better modeled on smother and more realistic landscapes, but keeping other parameters the same those are landscapes on which it is groups of the best performing that do better. Smoother landscapes seem to vindicate both the concept and the value of expertise. Change in other parameters, however, also vindicates diversity. With an increase in the pool of available heuristics, diverse groups again do better. Group dynamics makes a difference as well; simultaneous ‘tournament’ deliberation in a group in place of the ‘relay’ deliberation in Hong and Page’s original model further emphasizes an advantage for diversity. ‘Tournament’ 2 dynamics particularly shows the advantage of mixed groups that include both experts and non-experts. As a whole, our modeling results suggest that relative to problem characteristics and conceptual resources, the wisdom of crowds and the wisdom of the few each have a place. We regard ours as a step toward attempting to calibrate their relative virtues in different modelled contexts of intellectual exploration. (shrink)

The structure of communication networks can be more or less “democratic”: networks are less democratic if (a) communication is more limited in terms of characteristic degree and (b) is more tightly channeled to a few specifc nodes. Together those measures give us a two-dimensional landscape of more and less democratic networks. We track opinion volatility across that landscape: the extent to which random changes in a small percentage of binary opinions at network nodes result in wide changes across the network (...) as a whole. If wide and frequent swings of popular opinion are taken as a mark of instability, democratic communication networks prove far more stable than anti-democratic ones. In a fnal section, we consider the democratic or anti-democratic character of networks that respond to volatility by rewiring at random, in a search for community, or in a search for a leader.

A first take, matured in later work, in modeling belief polarization.

The March 2002 symposium Human Dignity and Reproductive Technology brought together philosophers, theologians, scientists, lawyers, and scholars from across the United States. The essays of this book are the contributions of the symposium's participants.

Authenticity in Culture, Self, and Society addresses the problems surrounding the concept of authenticity by offering its first sociological analysis. Compiled by a team of experts from a variety of disciplinary backgrounds, it provides readers with a survey of original empirical studies focused on its experience, negotiation, and social relevance at the levels of self, culture, and specific social settings.

In this essay, I review the concept of visioneering as I developed it and consider the ways in which other scholars have deployed it.

This paper introduces the special issue of papers selected from those presented at the International Conference on Business Ethics in Transitional Economies, held March 20–22, 2002 in Celakovice and Prague, Czech Republic. A brief background on the conference is given, and a summary of the papers offered in this special issue is provided.

This article presents texts recovered by post-processing of multispectral images from the fifth- or sixth-century underwriting of the palimpsest Codex Climaci Rescriptus. Texts identified include the Anonymous II Proemium to Aratus’ Phaenomena, parts of Eratosthenes’ Catasterisms, Aratus’ Phaenomena lines 71–4 and 282–99 and previously unknown text, including some of the earliest astronomical measurements to survive in any Greek manuscript. Codex Climaci Rescriptus also contains at least three astronomical drawings. These appear to form part of an illustrated manuscript, with considerable textual (...) value not merely on the basis of its age but also of its readings. The manuscript undertexts show significant overlap with the Φ Edition, postulated as ancestor of the various Latin Aratea. (shrink)

As identity and authenticity discourses increasingly saturate everyday life, so too have these concepts spread across the humanities and social sciences literatures. Many scholars may be interested in identity and authenticity, but lack knowledge of paradigmatic or disciplinary approaches to these concepts. This volume offers readers insight into social constructionist approaches to identity and authenticity. It focuses on the processes of identification and authentication, rather than on subjective experiences of selfhood. There are no attempts to settle what authentic identities are. (...) On the contrary, contributors demonstrate that neither identities nor their authenticity have a single or fixed meaning. Chapters provide exemplars of contemporary research on identity and authenticity, with significant diversity among them in terms of the identities, cultural milieu, geographic settings, disciplinary traditions, and methodological approaches considered. Contributors introduce readers to a number of established and emerging identity groups from sites around the world, from yogis and punks to fire dancers and social media influencers. Their conceptual work stretches from the micro-analytic to the ethno-national as authors employ a variety of qualitative methods including ethnographic fieldwork, interviewing, and the collection and analysis of naturally-occurring interactions. Several of the chapters look directly at identification and authentication, while others focus on the social and cultural backdrops that structure these practices-what unites them is the adoption of social constructionist sensibilities. This book will appeal to anyone interested in understanding identity and authenticity. (shrink)

Paul Hirst’s reconceptualization of his epistemology provides a basis for this exploration of the various aspects of the rationale for teaching literature. The article reflects the close analysis of knowledge and the curriculum in his early work and develops insights in his later work. This leads to the identification of five strands that form the rationale for the role of literature within the curriculum. The first strand refers to the knowledge of context, cultural background, or information necessary to engage with (...) many works of literature. The second strand concerns the role of literature in providing pleasure. The third strand considers the role of literature in offering multiple forms of understanding and insight. Strands four and five address the place of literature in the educational context. The fourth strand refers to the possibilities offered for education in language by the close study of literary texts. The fifth strand concerns the honing of the ability to propose and defend arguments in the interpretation of texts as a conduit to the development of one aspect of practical reason. (shrink)

Agent-based models have played a prominent role in recent debates about the merits of democracy. In particular, the formal model of Lu Hong and Scott Page and the associated “diversity trumps ability” result has typically been seen to support the epistemic virtues of democracy over epistocracy (i.e., governance by experts). In this paper we first identify the modeling choices embodied in the original formal model and then critique the application of the Hong-Page results to philosophical debates on the relative merits (...) of democracy. In particular we argue that the “best-performing agents” in Hong-Page model should not be interpreted as experts. We next explore a closely related model in which best-performing agents are more plausibly seen as experts and show that the diversity trumps ability result fails to hold. However, with changes in other parameters (such as the deliberation dynamic) the diversity trumps ability result is restored. The sensitivity of this result to parameter choices illustrates the complexity of the link between formal modeling and more general philosophical claims; we use this debate as a platform for a more general discussion of when and how agent-based models can contribute to philosophical discussions.

This article aims to describe the last 10 years of the collaborative scientific endeavors on polarization in particular and collective problem-solving in general by our multidisciplinary research team. We describe the team’s disciplinary composition—social psychology, political science, social philosophy/epistemology, and complex systems science— highlighting the shared and unique skill sets of our group members and how each discipline contributes to studying polarization and collective problem-solving. With an eye to the literature on team dynamics, we describe team logistics and processes that (...) we believe make our multidisciplinary team persistent and productive. We emphasize challenges and difficulties caused by disciplinary differences in terms of terminology, units/levels of analysis, methodology, and theoretical assumptions. We then explain how work disambiguating the concepts of polarization and developing an integrative theoretical and methodological framework with complex systems perspectives has helped us overcome these challenges. We summarize the major findings that our research has produced over the past decade, and describe our current research and future directions. Last, we discuss lessons we have learned, including difficulties in a “three models” project and how we addressed them, with suggestions for effective multidisciplinary team research. (shrink)

We motivate a picture of social epistemology that sees forgetting as subject to epistemic evaluation. Using computer simulations of a simple agent-based model, we show that how agents forget can have as large an impact on group epistemic outcomes as how they share information. But, how we forget, unlike how we form beliefs, isn’t typically taken to be the sort of thing that can be epistemically rational or justified. We consider what we take to be the most promising argument for (...) this claim and find it lacking. We conclude that understanding how agents forget should be as central to social epistemology as understanding how agents form beliefs and share information with others. (shrink)
