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)

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

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.

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.

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)

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.

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.

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)

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)

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)

Graphical AbstractGene editing with engineered nucleases introduce double-strand breaks that are repaired by error-prone nonhomologous end-joining (NHEJ). In article number 1900126, Sara G. Trimidal et al. propose that the length and type or resulting indels can now be controlled by editing with different engineered nucleases or by manipulating the expression of NHEJ genes.

Genome editing with engineered nucleases (GEENs) introduce site‐specific DNA double‐strand breaks (DSBs) and repairs DSBs via nonhomologous end‐joining (NHEJ) pathways that eventually create indels (insertions/deletions) in a genome. Whether the features of indels resulting from gene editing could be customized is asked. A review of the literature reveals how gene editing technologies via NHEJ pathways impact gene editing. The survey consolidates a body of literature that suggests that the type (insertion, deletion, and complex) and the approximate length of indel edits (...) can be somewhat customized with different GEENs and by manipulating the expression of key NHEJ genes. Structural data suggest that binding of GEENs to DNA may interfere with binding of key components of DNA repair complexes, favoring either classical‐ or alternative‐NHEJ. The hypotheses have some limitations, but if validated, will enable scientists to better control indel makeup, holding promise for basic science and clinical applications of gene editing.

The question of the ethical life is arguably one of the most compelling, and urgent, questions of our time. As Peter Singer, among others, has pointed out, almost 10 million children die each year due to poverty, some of whom would not die if the amount of aid that we now offer increases significantly. As Singer has also pointed out, the exploitation of human beings and other animals is a major ethical and practical concern. There can be little (...) reasonable doubt that pain and suffering abound, in the world today, due to many causes such as poverty, disease, environmental degradation and destruction and anthropocentrism among others, just as there can be little reasonable doubt that some of the pain and suffering is preventable. So, what does it mean to live ethically today? Does it mean taking the point of view of the universe, as Sidgwick put it, memorably, rather than a narrow anthropocentric or speciesist view? Does it mean living in accordance with duties or obligations, or in light of recognised virtues, or with the minimisation of pain and suffering primarily in mind? Does it entail a consideration of the interests of other species and a rejection of the principle of the sanctity of human life? Does it mean not eating animals when other healthy alternatives are available, especially when those animals have been treated in ways that are inconsistent with their interests, whatever they may be? Does it mean taking active steps to reduce poverty on our part on a day to day basis? Is ethics exhausted in some sense today? And if we could reach some consensus on these questions, what difference would the ethical life make? Some argue that speciesism and the exploitation of human beings and other animals might diminish; that pain and suffering, especially gratuitous pain and suffering, would decrease, or at the very least, not increase; or that we will become more aware of the limitations of things such as "the traditional ethic of the sanctity of life", as Singer calls it. Some argue that the ethical life is closely related to a life of relationships, reflection and deliberation, all of which deepen our understanding and enrich us personally. Others argue that the ethical life is closely related to our search for a meaningful life - that the ethical life can help us to find meaning in a world in which "meaning", defined broadly, can seem elusive, enigmatic or unsubstantial. These and related issues and questions are explored in this collection, which illustrates the relevance, vitality and dynamism of ethics today. (shrink)

Peter Singer argues that when some fail to do their part in alleviating suffering, the rest of us must take up their slack. In response, L. J. Cohen, Liam Murphy, and David Miller argue that such a requirement would be unfair. No one, they contend, should be required to contribute more than she would be required to under full compliance. I argue against Cohen, Murphy, and Miller that we are obligated to take up slack left by noncontributors, but agree (...) that we are thereby treated unfairly. Drawing on the literatures on group causation and moral responsibility, I argue that noncontributors wrong those they fail to help and those who take up their slack. I refer to the latter kind of wrong as “burden dumping.” Furthermore, I argue that my account applies whether we conceive of rescue duties as discretionary or nondiscretionary. One might think that if my duties to rescue do not require me to contribute to any particular rescue effort, I do not dump burdens on anyone when I do nothing. In reply, I argue that when I have a nondiscretionary duty to contribute to a particular rescue effort, I unfairly dump burdens on those contributing to that effort when I fail to do my part. Similarly, when my duty to rescue is discretionary and I do nothing, I unfairly dump burdens on everyone whose rescue efforts I might have contributed to. Using this apparatus, we can account for the force of arguments such as Singer’s as well as the idea that those who dump burdens are blameworthy for treating other rescuers unfairly. (shrink)

The publication of 'Animal Rights and Souls in the 18th Century' will be welcomed by everyone interested in the development of the modern animal liberation movement, as well as by those who simply want to savour the work of enlightenment thinkers pushing back the boundaries of both science and ethics. At last these long out-of-print texts are again available to be read and enjoyed - and what texts they are! Gems like Bougeant's witty reductio of the Christian view of animals (...) are included together with path-breaking works of ethics such as Primatt's A Dissertation on the Duty of Mercy and Sin of Cruelty to Brute Animals . There are works I have never seen before, including the remarkable Cry of Nature by the Scottish revolutionary Jacobin, John Oswald. In this set, everyone will find something novel, delightful and truly enlightening. - Peter Singer The discussion of animal rights and the moral status of animals, so prevalent in the late twentieth century, has its roots in the mid to late eighteenth century. Some of the themes we consider of recent invention - the legal standing of animals, the ethical status of vegetarians, cruelty towards animals, ultimately resulting in cruelty to humans - are of long standing. But in the eighteenth-century literature they are interconnected with theological issues surrounding animal souls, the birth of the life sciences, the great chain of being and other peculiarly eighteenth-century problems. This collection explores the exciting early discussions of moral theories concerning animals, placing them within their historical and social context. It reveals that issues such as vivisection, animal souls and vegetarianism were very much live philosophical subjects 200 years ago. The six volumes reprinted here includes complete works and edited extracts from such key eighteenth-century thinkers as Oswald, Primatt, Smellie, Monboddo and Jenyns. Many of the materials are extremely rare and never previously reprinted. The collection, edited with a new introduction and bio-bibliography by Aaron V. Garrett provides valuable original source material to supplement contemporary discussions of animal rights. --18th-century material on the theme of animal rights and practical ethics --an important supplement to contemporary animal rights discussions --provides a broader account of early discussions of the 'science of human nature' through animals --widens our understanding of 18th-century ethics through an important area of practical ethics --includes many scarce texts, most of which have never been reprinted before.

How do we know right from wrong? Do we even have moral knowledge? Moral epistemology studies these and related questions about our understanding of virtue and vice. It is one of philosophy’s perennial problems, reaching back to Plato, Aristotle, Aquinas, Locke, Hume and Kant, and has recently been the subject of intense debate as a result of findings in developmental and social psychology. Throughout the book Zimmerman argues that our belief in moral knowledge can survive sceptical challenges. He also draws (...) on a rich range of examples from Plato’s Meno and Dickens’ David Copperfield to Bernard Madoff and Saddam Hussein. (shrink)

Since its original publication in 1975, this groundbreaking work has awakened millions of people to the existence of "speciesism"—our systematic disregard of nonhuman animals—inspiring a worldwide movement to transform our attitudes to animals and eliminate the cruelty we inflict on them. In Animal Liberation, author Peter Singer exposes the chilling realities of today’s "factory farms" and product-testing procedures—destroying the spurious justifications behind them, and offering alternatives to what has become a profound environmental and social as well as moral issue. (...) An important and persuasive appeal to conscience, fairness, decency, and justice, it is essential reading for the supporter and the skeptic alike. (shrink)

It is widely held that, in his pre-Critical works, Kant endorsed a necessitation account of laws of nature, where laws are grounded in essences or causal powers. Against this, I argue that the early Kant endorsed the priority of laws in explaining and unifying the natural world, as well as their irreducible role in in grounding natural necessity. Laws are a key constituent of Kant’s explanatory naturalism, rather than undermining it. By laying out neglected distinctions Kant draws among types of (...) natural law, grounding relations, and ontological levels, I show that his early works present a coherent and sophisticated laws-first account of the natural order.

One of the most profound interactions that can occur between people, apologies have the power to heal humiliations, free the mind from deep-seated guilt, remove the desire for vengeance, and ultimately restore broken relationships. With On Apology, Aaron Lazare offers an eye-opening analysis of this vital interaction, illuminating an often hidden corner of the human heart. He discusses the importance of shame, guilt, and humiliation, the initial reluctance to apologize, the simplicity of the act of apologizing, the spontaneous generosity (...) and forgiveness on the part of the offended, the transfer of power and respect between two parties, and much more. Readers will not only find a wealth of insight that they can apply to their own lives, but also a deeper understanding of national and international conflicts and how we might resolve them. The act of apologizing is quite simply immensely fulfilling. On Apology opens a window onto this common occurrence to reveal the feelings and actions at the heart of this profound interaction.

Prior research on the influence of various ways of framing anthropogenic climate change do not account for the organized ACC denial in the U.S. media and popular culture, and thus may overestimate these frames' influence in the general public. We conducted an experiment to examine how Americans' ACC views are influenced by four promising frames for urging action on ACC —when these frames appear with an ACC denial counter-frame. This is the first direct test of how exposure to an ACC (...) denial message influences Americans' ACC views. Overall, these four positive frames have little to no effect on ACC beliefs. But exposure to an ACC denial counter-frame does significantly reduce respondents' belief in the reality of ACC, belief about the veracity of climate science, awareness of the consequences of ACC, and support for aggressively attempting to reduce our nation's GHG emissions in the near future. Furthermore, as expected by the Anti-Reflexivity Thesis, exposure to the ACC denial counter-frame has a disproportionate influence on the ACC views of conservatives, effectively activating conservatives' underlying propensity for anti-reflexivity.

Bayesian Conditionalization is a widely used proposal for how to update one’s beliefs upon the receipt of new evidence. This is in part because of its attention to the totality of one’s evidence, which often includes facts about what one’s new evidence is and how one has come to have it. However, an increasingly popular position in epistemology holds that one may gain new evidence, construed as knowledge, without being in a position to know that one has gained this evidence. (...) These are cases of KK-Failure, cases where one knows p but is not in a position to know that one knows p. This paper assumes that certain KK-Failures are possible and argues that Conditionalization goes wrong in those cases. (shrink)

Adam Smith sought to explain the persistence of slavery as an institution in Wealth of Nations and Lectures on Jurispridence. In order to accomplish this he also drew on arguments he had developed in the Theory of Moral Sentiments. The result was a sophisticated explanation which bridged economic, psychological, and moral considerations. After presenting Smith’s explanation I will consider a discussion of the moral wrong of slavery in Ottobah Cugoano, the author of the incisive criticism of the slave trade Thoughts (...) and Sentiments on the Evil of Slavery (1787). I will suggest that Cugoano’s account of what is morally wrong in slavery shows an important lacuna in Smith‘s views. (shrink)

Does a commitment to mereological universalism automatically bring along a commitment to the controversial doctrine of mereological extensionalism—the view that objects with the same proper parts are identical? A recent argument suggests the answer is ‘yes’. This paper attempts a systematic response to the argument, considering nearly every available line of reply. It argues that only one approach—the mutual parts view—can yield a viable mereology where universalism does not entail extensionalism.

The aim of this paper is to bring recent work on metaphysical grounding to bear on the phenomenon of social construction. It is argued that grounding can be used to analyze social construction and that the grounding framework is helpful for articulating various claims and commitments of social constructionists, especially about social identities, e.g., gender and race. The paper also responds to a number of objections that have been leveled against the application of grounding to social construction from Elizabeth Barnes, (...) Mari Mikkola, and Jessica Wilson.

The thesis that aesthetic testimony cannot provide aesthetic justification or knowledge is widely accepted--even by realists about aesthetic properties and values. This Kantian position is mistaken. Some testimony about beauty and artistic value can provide a degree of aesthetic justification and, perhaps, even knowledge. That is, there are cases in which one can be justified in making an aesthetic judgment purely on the basis of someone else's testimony. But widespread aesthetic unreliability creates a problem for much aesthetic testimony. Hence, most (...) testimony about art does not have much epistemic value. The situation is somewhat different with respect to aesthetic testimony about nature, proofs, and theories. (shrink)

I reconstruct J. H. Lambert’s views on how practical grounds relate to epistemic features, such as certainty. I argue, first, that Lambert’s account of moral certainty does not involve any distinctively practical influence on theoretical belief. However, it does present an interesting form of fallibilism about justification as well as a denial of a tight link between knowledge and action. Second, I argue that for Lambert, the persistence principle that underwrites induction is supported by practical reasons to believe; this indicates (...) that Lambert is a moderate pragmatist about reasons for theoretical belief.

This paper is a systematic exploration of non-wellfounded mereology. Motivations and applications suggested in the literature are considered. Some are exotic like Borges’ Aleph, and the Trinity; other examples are less so, like time traveling bricks, and even Geach’s Tibbles the Cat. The authors point out that the transitivity of non-wellfounded parthood is inconsistent with extensionality. A non-wellfounded mereology is developed with careful consideration paid to rival notions of supplementation and fusion. Two equivalent axiomatizations are given, and are compared to (...) classical mereology. We provide a class of models with respect to which the non-wellfounded mereology is sound and complete.

Timothy Williamson has argued that a person S ’s total evidence is constituted solely by propositions that S knows. This theory of evidence entails that a false belief can not be a part of S ’s evidence base for a conclusion. I argue by counterexample that this thesis (E = K for now) forces an implausible separation between what it means for a belief to be justified and rational from one’s perspective and what it means to base one’s beliefs on (...) the evidence. Furthermore, I argue that E = K entails the implausible result that there are cases in which a well-evidenced belief necessarily can not serve as evidence for a further proposition. (shrink)

The distribution of moral properties supervenes on the distribution of natural properties, and this provides a puzzle for non-naturalism: what could explain supervenience if moral properties are not natural properties? Enoch claims moral principles explain supervenience. But this solution is incomplete without an account of what moral principles and properties are, and what relation holds between them. This paper begins to develop such an account by exploring analogous issues for Realism about Laws of nature in philosophy of science. Appealing to (...) Mumford’s Central Dilemma for Realism about Laws, I argue that for moral principles to explain supervenience, moral properties must be ontologically dependent on the principles. I suggest that moral properties are relations between moral principles and natural properties. I also explore what it would take to adapt this explanation to a pluralistic theory of morality. Contributory reasons avoid the Cartwright Problem for Laws in a way component forces cannot. (shrink)

The dominant theory of parts and wholes – classical extensional mereology – has faced a number of challenges in the recent literature. This article gives a sampling of some of the alleged counterexamples to some of the more controversial principles involving the connections between parthood and identity. Along the way, some of the main revisionary approaches are reviewed. First, counterexamples to extensionality are reviewed. The ‘supplementation’ axioms that generate extensionality are examined more carefully, and a suggested revision is considered. Second, (...) the paper considers an alternative approach that focuses the blame on antisymmetry but allows us to keep natural supplementation axioms. Third, we look at counterexamples to the idempotency of composition and the associated ‘parts just once’ principle. We explore options for developing weaker mereologies that avoid such commitments.
