While epistemic democrats have claimed that majority rule recruits the wisdom of the crowd to identify correct answers to political problems, the conjecture remains abstract. This article illustrates how majority rule leverages the epistemic capacity of the electorate to practically enhance the instrumental value of elections. To do so, we identify a set of sufficient conditions that effect such a majority rule mechanism, even when the decision in question is multidimensional. We then look to the case of sociotropic economic voting (...) in US presidential elections to provide empirical tractability for these conditions. We find that absent such an epistemic capacity a number of presidential elections might well have been decided differently. By generating clear conditions for the plausibility of claims made by epistemic democrats, and demonstrating their correspondence to empirical data, this article strengthens the broader instrumental grounds recommending democracy.

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)

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)

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.

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.

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)

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)

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)

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.

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.

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

Supervaluationism is often described as the most popular semantic treatment of indeterminacy. There’s little consensus, however, about how to fill out the bare-bones idea to include a characterization of logical consequence. The paper explores one methodology for choosing between the logics: pick a logic thatnorms beliefas classical consequence is standardly thought to do. The main focus of the paper considers a variant of standard supervaluational, on which we can characterizedegrees of determinacy. It applies the methodology above to focus ondegree logic. (...) This is developed first in a basic, single-premise case; and then extended to the multipremise case, and to allowdegreesof consequence. The metatheoretic properties of degree logic are set out. On the positive side, the logic is supraclassical—all classical valid sequents are degree logic valid. Strikingly, metarules such as cut and conjunction introduction fail. (shrink)

In this article I argue (against the views of Russell Dancy and Gregory Vlastos, but in support of the views of R. E. Allen, Gail Fine, and Francesco Fronterotta) that Euthyphro 5c-d and 6d-e show that Socrates had a metaphysics, early version of the theory of forms. I disagree with Fronterotta only on the separation of the forms in the Euthyphro.

Socrates is one the most important thinkers in western philosophy, yet he remains enigmatic, having left behind no works of his own. Instead, his thought is understood primarily through the work of his followers. In this accessible introduction, William Prior assesses Socrates the man, his famous trial, and the nature of his philosophy.

The idea of role‐playing makes some people nervous – even some people who play role‐playing games (RPGs). So the idea of immersion is central to understanding how Dungeons Dragons and other aspects of participatory culture work. Phenomenology is a kind of “philosophy of mind” associated with the works of twentieth‐century philosophers Edmund Husserl, Martin Heidegger, Jean‐Paul Sartre, and Maurice Merleau‐Ponty, among others. The domain of phenomenology encompasses the entire range of experiences in the world, paying attention to what Husserl called (...) “intentionality,” or how our consciousness is directed toward particular objects in the world. The fact that this is presented as an atypical approach to play, or at least one that requires some effort, invites us to ask about typical modes of play if visualization of in‐game events is not that mode. This chapter concluded by scratch the surface of a complete phenomenological description of role‐playing. (shrink)

This essay examines the role of non-existent objects in "epistemological ontology"--the study of the entities that make thinking possible. An earlier revision of Meinong's Theory of Objects is reviewed, Meinong's notions of Quasisein and Aussersein are discussed, and a theory of Meinongian objects as "combinatorially possible" entities is presented.

Can one coherently integrate Darwin's view of evolution with an affirmation of the value of existence? In this fresh, lean, and substantive volume, William Meyer addresses this important question. By carefully analyzing Darwin's own writings and by drawing on the philosophical perspectives of William James, Alfred North Whitehead, and others, Meyer persuasively redirects the cultural conversation about Darwin away from the retrospective question of origins toward the prospective question concerning the ultimate significance of evolutionary life. As James recognized, (...) the question about the reality of God is more critical for the forward-looking question of value than it is for the backward-looking question of origins. Darwin was a theist in search of a better theism, and because theology had not yet caught up to him, he became increasingly agnostic and caught between his mechanistic understanding of nature, on the one hand, and his affirmation of the value and beauty of the world, on the other. Whitehead's philosophy of organism offers a way to integrate Darwin's evolutionary insights with his affirmation of the grandeur of nature. Meyer's clearly written and richly argued book enables us to integrate our evolutionary understanding of the world with our experience of value within it. (shrink)

Disney's computer‐animated musical film, Moana tells the tale of Moana, the daughter of Tui, the chief of a Polynesian island, Motunui. Bound by the legendary tradition of her ancestors, Moana is expected to follow her lineage and take over as chief when she grows up. As the authors dig beneath the surface level of the story, they find a metaphorical and philosophical level to Moana's journey. The story of Moana has layers. First, it is literally a tale of Moana's voyage (...) outside beyond the reef so that she can restore the heart of Te Fiti and save the people of Motunui. She closes this tale with a happy ending as she simultaneously lives the life that she freely chooses, becomes the leader of her people (by saving them) as her parents wanted, and honors her tradition insofar as she restores her ancestors' tradition of wayfinding.

This article compares topographical and archaeological remains of the Thermopylae frontier with the ancient testimonia of the sixth century historian Procopius of Caesareia (De aedificiis4.2.1.–22). It was revealed that: many of the frontier fortifications described were initially built before the sixth century; the fortified κλεισούρα mentioned should be equated with the Dhéma Pass; and the commercial settlement of Myropóles is best identified with the modern village of Káto Dhió Vouná. Written in Attic prose, this passage represents a rhetorical exercise, the (...) climax of which turned not on the ancient battlefield of Thermopylae, but rather on a mountain pass and it's highway that neutralized the Thermopylae defenses if they were ever controlled by the enemy. We were told that only the Emperor Justinian's wisdom could grasp this critical fact. Additionally, Procopius employed many rhetorical devices in this narrative: τóπος, χρóνος,, ἄγαλμα, ἔκφρασις, πανηγρικóς and employed imperial propaganda, praise, and exaggeration as well. In short, the passage is a classic example of selective story telling that may have found its inspiration in the Hunnic raid of 539/540 and the Herodotean account of the Persian invasion of 480 BC. While Procopius' account remains our best topographical description of the late antique Thermopylae frontier, one can only say that more archaeological questions were left unanswered than were resolved. In short, as an archaeological source, theDe aedificiisis a disappointing and vexing resource filled with equivocations. Finally, one may doubt that Procopius ever did visit the Thermopylae frontier, even though during his career he certainly had ample opportunity to do so. His account, therefore, must have been based upon secondary sources, whether imperial archival material, itineraries, or military staff reports and were not the result of personal autopsy. (shrink)

Aquinas' theology can be understood only if one comes to grips with his metaphysics of being. The relevance of this perspective is exhibited in his treatment of topics like creation, goodness, happiness, truth, freedom of the will, the unity of the human being, prayer and providence, God's personhood, divine love, God and violence, God's unknowablility, the Incarnation, the Trinity, God's existence, theological language and even laughter. This book endeavors to treat these questions in a clear and convincing language. Is there (...) a better method for improving one's own theology than by grappling with the arguments of Thomas Aquinas? (shrink)

We review the role of reference within Davidson's T‐theoretic account of language and examine his contention that reference is inscrutable. More generally, we look at the explanatory role of reference in the context of Davidson's philosophy: whether there are explanations that directly appeal to reference, and whether there are explanations that appeal to beliefs about reference.

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)

Trotz eines verbreiteten Zweifels gegenüber Wahrheitsansprüchen wird in vielen persönlichen und sozialen Lebensbereichen Wahrheit selbstverständlich vorausgesetzt. Ohne Wahrheit kann keine Gesellschaft bestehen. Gewissen, Entscheidungsfreiheit, Menschenrechte, der Glaube an Gott, selbst der Zweifel, die Verständigung über Lebensziele und die Erfahrung von Glück sind ohne Wahrheit nicht möglich. Das Buch ergründet und entfaltet die Einsicht, dass der Mensch das Wahrheitswesen ist. Die Erkenntnis, wie sie sich bei Thomas von Aquin findet, dass Wahrheit auf der höchsten Ebene ihrer Abstraktion gedacht werden muss, dient (...) dabei bis heute als Verständnisschlüssel auch für unseren zeitgenössischen Begriff von Wahrheit.
