Collective Epistemology

Politics is full of people who don't care about the facts. Still, while not caring about the facts, they are often concerned to present themselves as caring about them. Politics, in other words, is full of bullshitters. But why? In this paper I develop an incentives-based analysis of bullshit in politics, arguing that it is often a rational response to the incentives facing different groups of agents. In a slogan: bullshit in politics pays, sometimes literally. After first outlining an account (...) of bullshit, I discuss the incentives driving three different groups of agents to bullshit: politicians, the media, and voters. I then examine several existing proposals to combat bullshit in politics, arguing that each will fail because they ignore the relevant underlying incentives. I conclude somewhat pessimistically that a certain amount of bullshit in politics is inevitable. (shrink)

Conversation, dialogue, reasonable disagreement, and the acquisition of knowledge through the words of others, all of this has always been at the center of philosophers’ concerns since the emergence of philosophy in Ancient Greece. It is also important to recognize that in contemporary philosophy, marked by the linguistic turn, there is a wealth of intellectual production on ethical, psycho-linguistic, logical-linguistic, and pragmatic aspects of the conversation. Despite all this, this is the first collection of texts dedicated exclusively to the strictly (...) epistemic aspects of this phenomenon which is so decisive for the very constitution of our humanity. This book brings together the contributions of fifteen leading philosophers on some of the most relevant issues of what we could call the Epistemology of Conversation. (shrink)

Transparency accounts have become one of the main contenders for an adequate theory of self-knowledge. However, for the most part, work on transparent self-knowledge has solely focused on individual agents. In this paper, it is argued that transparency accounts have distinct advantages when we apply them beyond individual agents to social groups. It is shown that transparency accounts of self-knowledge are well-suited to apply to group agents by providing three arguments: the first argument shows that transparency accounts of group self-knowledge (...) can capture the relevant phenomenology well; the second argument suggests that transparency accounts of group self-knowledge are particularly economical. They do not need to posit any new capacities, or new properties of group mental states and therefore avoid commitment to dubious ontological features for social groups, such as distinct introspective faculties in groups. Finally, the third argument shows that transparency accounts are positioned well to explain the privilege and peculiarity of group self-knowledge. No single one of these arguments is decisive in favour of transparent group self-knowledge, but together they show that transparency accounts provide a promising route to understanding group self-knowledge.

In order to make sense of collective doxastic reasons we need an account of group belief. Once we arrive at a more nuanced understanding of group belief it turns out that for some group beliefs we need not invoke collective epistemic reasons. However, we do need them for better understanding how and why different social identity groups will hold beliefs whose evidence-base is irreducibly social and tied to them being that kind of group. This short article is a commentary on (...) Veli Mitova's 2022 article "The collective epistemic reasons of social-identity groups". (shrink)

This thesis provides a novel account of arrogance and applies it to both individuals and collectives. In Chapter 1, I introduce and summarise the main aims and contributions of the thesis and note its omissions. In Chapter 2, I introduce a variety of plausible examples of individual arrogance and survey extant philosophical accounts of the trait. I argue, contra two contemporary accounts, that arrogance is an essentially interpersonal vice. I also argue for the novel view that arrogance can not only (...) involve feelings of superiority to or uniqueness from others but also feelings of similarity. In Chapter 3, I elaborate a novel approach to arrogance, understood as principally involving making undue assumptions of license. I explain how this account can disaggregate moral and epistemic forms of arrogance and argue that even highly domain-specific manifestations of arrogance can be conceived of as character traits. In Chapter 4, I use the analysis developed in earlier chapters to assess how we should understand the arrogance of groups. I argue that claims of group arrogance found in the extant philosophical literature involve sub-agential groups that are not paradigmatic group agents. An account of collective arrogance that caters to such groups is therefore required. The chapter proceeds to argue that prominent approaches to collective epistemic vice do not adequately account for these cases. In Chapter 5, I aim to fill this gap in our understanding by offering a novel account of collective arrogance. I argue that the dispositions of sub-agential groups can be understood in terms of the social norms that operate within them; that social norms underlie the arrogant dispositions of putatively arrogant groups. I conclude, in Chapter 6, by summarising the thesis’ key contributions and considering some of the questions that they raise for future research. (shrink)

A group is lying when it makes a statement that it believes to be untrue but wants the addressee(s) to believe. But how can we distinguish statements that the group believes to be untrue from honest group statements based on mistaken beliefs or confusion within the group? I will suggest a narrative constraint for honest group statements, made up of two components. Narrative coherence requires that a new group statement should not conflict with group knowledge on the matter, or beliefs (...) of relevant operative subgroups, unless a coherent rationale is given. Narrative intention looks at the process of gathering new evidence on the area of expertise of the group and requires that the group position behind the statement is formed in good faith. The narrative constraint will help to distinguish group lies from more innocent erroneous statements of group beliefs when there is an internal disagreement within the group, including in cases involving spokespersons.

This essay examines the contributions of Greek philosopher and theologian Christos Yannaras to the question of the relationship between faith and reason. Although a comprehensive analysis of the entire body of his work is beyond the scope of this project, we will attempt to demonstrate through a selective survey, from the early `On the Absence and Unknowability of God' (1970) to the later `The Effable and the Ineffable' (1999), that he presents a convincing `third way' between rationalism and deism. We (...) will argue that Yannaras accomplishes this by methodologically deconstructing the presuppositions of rationalism and advocating for a more `empirically correct' approach grounded in apophaticism and social verification of knowledge. In doing so, he introduces a paradigm that not only challenges the binary opposition between faith and reason but also establishes a distinctive point of encounter between Orthodox Christian theology and contemporary philosophical discourse.

This paper explores some features of the epistemic environment in social media and online communication. We argue that digital environments differ from offline ones in at least two ways: (a) online environments are thoroughly structured and programmed. Every action is defined and limited by the underlying code created by the system’s developers, providing the tools users need to navigate the online space. In contrast, offline environments are open to chance and unpredictability, allowing for events and actions that the system has (...) not predetermined; (b) every action is traced and used to evaluate levels of engagement with content and posts, with significant epistemic consequences. This creates a “dense” environment in which users are deeply entangled. In this regard, the concept of purely passive engagement is challenged, since activities such as just watching a video or reading a post can alter the epistemic landscape and promote specific content with which a person interacts. As a result, online social environments facilitate a variety of indirect communicative and epistemic activities across the network. Given this, the paper suggests that in such settings, attentional disengagement and avoidance should be considered a potential proactive way to modulate self-exposure. This strategy is aimed not only at protecting individuals from harmful content but also at actively shaping the information flow and knowledge structure within the environment. Managing one’s own attention can thus significantly influence how information is perceived and disseminated, essentially controlling the personal and collective epistemic environment. (shrink)

Our politics are increasingly polarised. Polarisation takes many forms. One is increasing clustering or 'ideological consistency,' whereby people hold down-the-line liberal or down-the-line conservative views on a wide range of political issues, even when those issues are orthogonal to each other. Some philosophers think that such clustering is indicative of irrationality, and so if you find yourself in one of several clusters of opinion, you should decrease your confidence that all your political beliefs are true. I argue that the reverse (...) is true, presenting a simple model of belief-formation on which finding yourself in one of several clusters of opinion on orthogonal issues should increase, rather than decrease, your confidence that all your beliefs are true.

Within collective epistemology, there is a class of theories that understand the epistemic status of collective attitude ascriptions, such as ‘the college union knows that the industrial action is going to plan’, or ‘the jury justifiedly believes that the suspect is guilty’, as saying that a sufficient subset of group member attitudes have the relevant epistemic status. In this paper, I will demonstrate that these summativist approaches to collective epistemology are incompatible with epistemic permissivism, the doctrine that a single body (...) of evidence may rationalize multiple doxastic attitudes. In particular, I will make use of epistemic permissivism to provide a general recipe for generating so-called divergence cases, which demonstrate situations in which rationality requires group-level and member-level attitudes to diverge. I will call this class of cases permissive divergence cases. While other divergence cases have been discussed in the literature, permissive divergence cases prove themselves to be less susceptible to many of the worries raised against their competitors, while being directly built on an often-defended epistemological thesis.

This paper contributes to the project of articulating and defending the supra-Bayesian approach to judgment aggregation. I discuss three cases where a person is disposed to defer to two different experts, and ask how they should respond when they learn about the opinion of each. The guiding principles are that this learning should go by conditionalisation, and that they should aim to update on the evidence that the expert had updated on. But this doesn’t settle how the update on pairs (...) of experts should go, because we also need to know how the experts are related. I work through three examples showing how the results change given different prior beliefs about this relationship. (shrink)

A probability aggregation rule assigns to each profile of probability functions across a group of individuals (representing their individual probability assignments to some propositions) a collective probability function (representing the group's probability assignment). The rule is “non-manipulable” if no group member can manipulate the collective probability for any proposition in the direction of his or her own probability by misrepresenting his or her probability function (“strategic voting”). We show that, except in trivial cases, no probability aggregation rule satisfying two mild (...) conditions (non-dictatorship and consensus preservation) is non-manipulable. (shrink)

Universities are knowledge institutions. Compared to several other knowledge institutions (e.g. schools, government research organisations, think tanks), research universities have unusual, anarchic organisational features. We argue that such anarchic features are not a weakness. Rather, they reflect the special standing of research universities among knowledge institutions. We contend that the distributed, self-organising mode of knowledge production maintains a diversity of approaches, topics and solutions needed in frontier research, which involves generating relevant knowledge under uncertainty. Organisational disunity and inconsistencies should sometimes (...) be protected by institutional structures and procedures in order for research universities to best serve their purpose as knowledge institutions. The quality control for the knowledge produced stems from knowledge fields, clusters of knowledge and research that exist beyond the confines of individual organisations. The diversity of epistemic contributions is therefore kept in check by the order imposed by the internal logic of science as a social practice. Our argument provides a new defence for the autonomy of research conducted at universities. (shrink)

Some incredibly far-fetched conspiracy theories circulate online these days. For most of us, clear evidence would be required before we’d believe these extraordinary theories. Yet, conspiracists often cite evidence that seems transparently very weak. This is puzzling, since conspiracists often aren’t irrational people who are incapable of rationally processing evidence. I argue that existing accounts of conspiracist belief formation don’t fully address this puzzle. Then, drawing on both philosophical and empirical considerations, I propose a new explanation that appeals to the (...) role of the imagination in conspiracist belief formation. I argue that conspiracists first become imaginatively absorbed in conspiracist narratives, where this helps to explain how they process their evidence. From there, we can better understand why they find this evidence so compelling, as well as the psychological role it plays in their belief forming processes. This account also has practical implications for combatting the spread of online conspiracy theories. (shrink)

In The Epistemology of Groups, Jennifer Lackey investigates the conditions for the possibility of groups telling lies. Central to this project is the goal of holding groups, and individuals within groups, accountable for their actions. I show that Lackey’s total account of group phenomena, however, may open up a means by which groups can evade accusations of having lied, thus allowing them to evade responsibility in precisely the way Lackey set out to avoid. Along the way, I also take note (...) of some interesting implications of Lackey’s view: that it makes groups uniquely susceptible to a lack of self-knowledge and that it creates an interesting mechanism by which groups can lie to themselves.

In this short paper, I critically examine Veli Mitova’s proposal that social-identity groups can have collective epistemic reasons. My primary focus is the role of privileged access in her account of how collective reasons become epistemic reasons for social-identity groups. I argue that there is a potentially worrying structural asymmetry in her account of two different types of cases. More specifically, the mechanisms at play in cases of “doxastic reasons” seem fundamentally different from those at play in cases of “epistemic-conduct (...) reasons”. The upshot is a need for further explanation of what unifies these dimensions of the account. (shrink)

When does a group justifiedly believe that p? One answer to this question has been developed first by Schmitt and then by Hakli: when the group members jointly accept a reason for the belief. Call this the joint acceptance account of group justification. Their answer has great explanatory power, providing us with a way to account for cases in which the group's justification can diverge from the justification individual members have. Unfortunately, Jennifer Lackey developed a powerful argument against joint acceptance (...) accounts. She argues that these accounts lead to epistemically arbitrary reasons and therefore justification at will. Group justification loses the necessary connection to the world to be truth-conducive. In this paper I develop a new form of a joint acceptance account that can deal with Lackey's examples: the anchored joint acceptance account of group justification. I argue that properly understanding the role of epistemic expectations can help us form the best version of a joint acceptance account. While justification is only generated by joint acceptance of evidence, the evidential expectations towards a group are anchored in the group members. This anchoring guarantees that groups cannot manipulate their ultima facie justification illegitimately. (shrink)

Much of our information comes to us indirectly, in the form of conclusions others have drawn from evidence they gathered. When we hear these conclusions, how can we modify our own opinions so as to gain the benefit of their evidence? In this paper we study the method known as geometric pooling. We consider two arguments in its favour, raising several objections to one, and proposing an amendment to the other.

Marine ecosystems are under increasing pressure from human activity, yet successful management relies on knowledge. The evidence-based policy (EBP) approach has been promoted on the grounds that it provides greater transparency and consistency by relying on ‘high quality’ information. However, EBP also creates epistemic responsibilities. Decision-making where limited or no empirical evidence exists, such as is often the case in marine systems, creates epistemic obligations for new information acquisition. We argue that philosophical approaches can inform the science-policy interface. Using marine (...) biosecurity examples, we specifically examine the epistemic challenges in the acquisition and acceptance of evidence to inform policy, discussing epistemic due care and biases in consideration of evidence.

В данной работе рассматриваются важнейшие вопросы о коллективном воображаемом и его отношениях с реальностью и истиной. Сначала мы рассмотрим эту тему в концептуальных рамках, а затем проведем соответствующий фактологический анализ наглядных поведенческих реалий. Мы будем опираться не только на методологию, но и, главным образом, на постулаты и положения аналитической философии, которые, безусловно, будут проявляться на протяжении всего исследования и могут быть идентифицированы по признакам, описанным Пересом : Рабосси (1975) отстаивает идею, что аналитическая философия может быть идентифицирована путем рассмотрения некоторых семейных (...) сходств. Он предлагает следующие семейные черты: позитивное отношение к научному знанию; осторожное отношение к метафизике; представление о философии как о концептуальной задаче, в которой в качестве метода используется концептуальный анализ; тесная связь между языком и философией; стремление к аргументированным ответам на философские проблемы; поиск концептуальной ясности. Эти базовые понятия включают в себя культурное, социальное, религиозное, научное, философское, моральное и политическое содержание, принадлежащее каждому и коллективному существованию. В данной статье мы не будем дискутировать и доказывать. Наша цель — не систематическая методология, не критика и не доказательство. Настоящая работа основана на аналитической рефлексии. Мы будем рассуждать как можно более полно и глубоко и излагать результаты своих размышлений. Несмотря на междисциплинарный характер темы и методологическую открытость к принятию вклада из любой области науки, данная работа относится к психологии и онтологии, или, другими словами, к социальной и онтологической психологии. Свободная методология, направляющая такие размышления, охватывает и рассматривает все, что приближается к согласованности с философской и психологической эпистемологией. Эта методология не гонится за доказательствами, а ищет взаимосвязь между существующими доказательствами любой природы и величины, выводя когерентный смысл реальных вещей. (shrink)

The my-side bias is a well-documented cognitive bias in the evaluation of arguments, in which reasoners in a discussion tend to overvalue arguments that confirm their prior beliefs, while undervaluing arguments that attack their prior beliefs. The first part of this paper develops and justifies a Bayesian model of myside bias at the level of individual reasoning. In the second part, this Bayesian model is implemented in an agent-based model of group discussion among myside-biased agents. The agent-based model is then (...) used to perform a number of experiments with the objective to study whether the myside bias hinders or enhances the ability of groups to collectively track the truth, that is, to reach the correct answer to a given binary issue. An analysis of the results suggests the following: First, whether the truth-tracking ability of groups is helped or hindered by myside bias crucially depends on how the strength of myside bias is differentially distributed across subgroups of discussants holding different beliefs. Second, small groups are more likely to track the truth than larger groups, suggesting that increasing group size has a detrimental effect on collective truth-tracking through discussion. (shrink)

Epistemic paternalism is the thesis that in some circumstances we are justified in interfering with the inquiry of others for their own epistemic good without consulting them on the issue. This paper addresses the issue of who is rationally entitled to undertake paternalistic interferences, and in virtue of which features one has this entitlement. First, it undermines the view according to which experts are the most apt people to act as paternalist interferers. Then it argues that epistemic authorities are in (...) a better position to satisfy the requirements of justified epistemic paternalism, when conceived according to the service model of epistemic authority. Finally, it offers a virtue‐based account of paternalist interferers and shows how it can apply to cases in which the interferer is a group or an institution. (shrink)

Are strangers sincere in their moral praise and criticism? Here we apply signaling theory to argue ceteris paribus moral criticism is more likely sincere than praise; the former tends to be a higher-fidelity signal (in Western societies). To offer an example: emotions are often self-validating as a signal because they're hard to fake. This epistemic insight matters: moral praise and criticism influence moral reputations, and affect whether others will cooperate with us. Though much of this applies to generic praise and (...) criticism too, moral philosophers should value sincere moral praise and moral criticism for several reasons: it (i) offers insight into how others actually view us as moral agents; (ii) offers feedback to help us improve our moral characters; and (iii) encourages some behaviors, and discourages others. And so as moral agents, we should care whether moral praise and moral criticism is sincere. (shrink)

Groups, like individuals, can communicate. They can issue statements, make promises, give advice. Sometimes, in doing so, they lie and deceive. The goal of this paper is to offer a precise characterisation of what it means for a group to make an assertion and to lie. I begin by showing that Lackey’s influential account of group assertion is unable to distinguish assertions from other speech acts, explicit statements from implicatures, and lying from misleading. I propose an alternative view, according to (...) which a group asserts a proposition only if it explicitly presents that proposition as true, thereby committing to its truth. This proposal is then put to work to define group lying. While scholars typically assume that group lying requires (i) a deceptive intent and (ii) a belief in the falsity of the asserted proposition, I offer a definition that drops condition (i) and significantly broadens condition (ii).

We routinely attribute beliefs to groups as diverse as committees, boards, populaces, research teams, governments, courts, juries, legislatures, markets, and even mobs. There are three points of contention in the literature when it comes to accounting for group beliefs. On the one hand, there is the dispute between so-called believers (those who claim that there is such a thing as group beliefs) and rejectionists (those who think that group beliefs are better understood as collective acceptances). On the other hand, there (...) is the dispute between summativists and non-summativists: those who respectively endorse and reject the idea that a group believes a proposition only if at least one member of the group also believes it. Finally, monists hold group beliefs are only of one kind and that it is in principle possible to offer a unified account of them that provides truth conditions that apply to all group ascriptions. Pluralists, on the other hand, defend that there is more than one kind of group belief, each requiring different accounts that provide different truth conditions that apply to some but not all group ascriptions. This chapter sides with believers and argues that group beliefs, unlike other group attitudes (e.g., group intentions), are best understood in pluralist, summative terms. (shrink)

This article introduces the concept of epistemic positioning to theorize the relationship between identity-based epistemic judgements and the reproduction of social inequalities, including those of gender and ethnicity/race, in the academia. Acts of epistemic positioning entail the evaluation of knowledge claims based on the speaker’s stated or inferred identity. These judgements serve to limit the scope of the knowledge claim, making it more likely speakers will be denied recognition or credit. The four types of epistemic positioning – bounding (reducing a (...) knowledge claim to elements of personal identity), domaining (reducing a knowledge claim to discipline or field associated with identity), non-attribution (using the claim without recognizing the author) and appropriation (presenting the claim as one’s own) – are mutually reinforcing. Given the growing importance of visibility and recognition in the context of increasing competition and insecurity in academic employment, these practices play a role in the ability of underrepresented groups to remain in the academic profession.

Linda Martín Alcoff and others have emphasised that the discipline of philosophy suffers from a ‘demographic problem’. The persistence of this problem is partly the consequence of various forms of resistance to efforts to address the demographic problem. Such resistance is complex and takes many forms and could be responded to in different ways. In this paper, I argue that our attempts to explain and understand the phenomenon of resistance should use a kind of explanatory pluralism that, following Quassim Cassam, (...) I call multidimensionalism. I describe four general kinds of resistance and consider varying explanations, focusing on those focused on vices and social structures. I argue that vice-explanations and structural- explanations are both mutually consistent and mutually entailing. If so, there is no need to choose between vice explanations and structural explanations or any other kinds of explanation. We can and should be multidimensionalists: using many together is better.

The United States of America launched a war against Iraq in 2003 claiming that Iraq possesses weapons of mass destruction, then it became clear to the world that this claim was not true, and people said: The American administration lied. The traditional theory of knowledge attributed knowledge to the individual knowing subject, and focused on individual actors and their belief states, such as "Ahmed believes in a certain proposition". As for attributing cognitive states to groups, such as “the American administration lied,” this is a shift in epistemology to the collective actor. The epistemology of groups is a subfield of social epistemology. It aims to explore the characteristics and cognitive processes at the group level. It appeared clearly at the beginning of the twenty-first century, so national and international conferences were held for it, and research and books appeared that deal with its basic topics such as group knowledge, group belief, group justification, group understanding, group rationality, and objectivity, group virtue, group difference, group polarization, and group intelligence, and so on. This book adds to the cutting-edge debates on social epistemology generally, and collective epistemology more specifically. Provides a very accessible path into the topic of an epistemology of groups, with conveniently organized chapters and technical terms clearly defined and explained. Develops theories that have appeal beyond philosophy, for disciplines such as economics, law, social psychology, and political science. (shrink)

Google Search is arguably one of the primary epistemic tools in use today, with the lion’s share of the search-engine market globally. Scholarship on countering the current scourge of misinformation often recommends “digital lit- eracy” where internet users, especially those who get their information from so- cial media, are encouraged to fact-check such information using reputable sources. Given our current internet-based epistemic landscape, and Google’s dominance of the internet, it is very likely that such acts of epistemic hygiene will take (...) place via Google Search. The question arises whether Google Search is fit for purpose, given the apparent misalignment the general epistemic goal of promoting true beliefs and the greater online commercial ecosystem in which it is embedded. I argue that Google Search is epistemically problematic as it stands, mainly due to the opacity related to the parameters it uses for personalising search results. I further argue that in as far as an ordinary internet user is legitimately ignorant of Google’s workings, uses it in an “ordinary manner”, and is generally unable to avoid using it in the current information environment, they are not ep- istemically blameworthy for any false beliefs that they acquire via it. I conclude that too much emphasis is currently placed on individual epistemic practices and not enough on our information environment and epistemic tools when it comes to countering misinformation.

The epistemic virtues and vices are typically defined in terms of effects or motivations related to the epistemic states of their possessors. However, philosophers have recently begun to consider _other-regarding_ epistemic virtues, traits oriented toward the epistemic flourishing of others. In a similar vein, this paper discusses _outward-facing_ epistemic vices, properties oriented toward the epistemic languishing of others. I argue for the existence of both reliabilist and responsibilist outward-facing vices, and illustrate how such vices negatively bear on the epistemic prospects (...) of others. I pay special attention to how outward-facing epistemic vices may manifest in online activities that promote the epistemic languishing of others by negatively influencing the online epistemic environment.

The aim of this paper is to show that the nascent field of ethics of collegiality may considerably benefit from a symbiosis with virtue and vice epistemology. We start by bringing the epistemic virtue and vice perspective to the table by showing that competence, deemed as an essential characteristic of a good colleague (Betzler & Löschke 2021), should be construed broadly to encompass epistemic competence. By endorsing the anti-individualistic stance in epistemology as well as context-specificity of epistemic traits, we show (...) how the individual vice of a colleague can have a positive epistemic outcome for the team while individual virtue can be damaging if all team members share it, thereby contributing to the negative epistemic outcome. We argue that the evaluation and analysis of collegial relationships should be done through one’s contribution to the team dynamics: without this collectivist perspective, the ethics of collegiality cannot aspire to become encompassing normative theory.

There’s a certain pleasure in fantasizing about possessing knowledge, especially possessing secret knowledge to which outsiders don’t have access. Such fantasies are typically a source of innocent entertainment. However, under the right conditions, fantasies of knowledge can become epistemically dangerous, because they can generate illusions of genuine knowledge. I argue that this phenomenon helps to explain why some people join and eventually adopt the beliefs of epistemic communities who endorse seemingly bizarre, outlandish claims, such as extreme cults and online conspiracy (...) theory groups. It can be difficult to grasp how members of such groups come to believe the theories they endorse. I argue that one route to such beliefs is via deep absorption in fantasies of knowledge, which can lead entire groups to become collectively detached from reality. (shrink)

Criminal juries make decisions of great importance. A key criticism of juries is that they are unreliable in a multitude of ways, from exhibiting racial or gendered biases, to misunderstanding their role, to engaging in impropriety such as internet research. Recently, some have even claimed that the use of juries creates injustice on a large-scale, as a cause of low conviction rates for sexual criminality. Unfortunately, empirical research into jury deliberation is undermined by the fact that researchers are unable to (...) study live juries. The indirect sources of evidence used by researchers suffer from various problems, the most important of which is dubious levels of ecological validity. Real jury research—studying live jury deliberation—is controversial. However, as I argue, the objections to it are unconvincing. There is in fact a moral imperative to facilitate real jury research.

When science makes cognitive progress, who or what is it that improves in the requisite way? According to a widespread and unchallenged assumption, it is the cognitive attitudes of scientists themselves, i.e. the agents by whom scientific progress is made, that improve during progressive episodes. This paper argues against this assumption and explores a different approach. Scientific progress should be defined in terms of potential improvements to the cognitive attitudes of those for whom progress is made, i.e. the receivers rather (...) than the producers of scientific information. This includes not only scientists themselves, but also various other individuals who utilize scientific information in different ways for the benefit of society as a whole. (shrink)

A popular view in mainstream social epistemology maintains that, in the face of a revealed peer disagreement over p, neither party should remain just as confident vis‐a‐vis p as she initially was. This ‘conciliatory’ insight has been defended with regard to individual epistemic peers. However, to the extent that (non‐summativist) groups are candidates for group knowledge and beliefs, we should expect groups (no less than individuals) to be in the market for disagreements. The aim here will be to carve out (...) and explore an extension of the conciliatory insight from individual peer disagreement to group peer disagreement; in doing so, I'll raise and address three key problems that face any plausible defence of such a constraint.

Groups can be epistemically vicious just like individuals. And just like individuals, groups sometimes want to do something about their vices. They want to change. However, intentionally combating one’s own vices seems impossible without detecting those vices first. Self-knowledge seems to provide a first step towards changing one’s own epistemic vices. I argue that groups can acquire self-knowledge about their epistemic vices and I propose an account of such collective self-knowledge. I suggest that collective self-knowledge of vices is partially based (...) on evidence that a group can generate by performing internal promptings. Whereas these promptings are done mentally in individual self-knowledge, these promptings are done by interactions of group members in the collective case. The group can then acquire inferential self-knowledge of their vices based on the evidence generated by the interactions within the group. Groups thereby bring themselves into a position from which they can combat and change those vices intentionally. (shrink)

What does it take for a group of people to know how to do something? An account of collective practical knowledge ought to be compatible with the linguistic evidence about the semantics for collective knowledge-how ascriptions, be able to explain the practicality of collective knowledge, be able to explain both the connection between individual and collective know-how and the possibility of a group knowing how to do something none of its members know, and be applicable to a suitably wide range (...) of groups. In this paper I develop a view which can meet all of these desiderata, which combines a Fragmented account of collective knowledge (Habgood-Coote, 2019a), with the view that practical knowledge is an Interrogative Capacity (Habgood-Coote, 2019b).

How a group G can know that p has been the subject of much investigation in social epistemology in recent years. This paper clarifies and defends a form of non-supervenient, non-summative group knowledge: G can know that p even if none of the members of G knows that p, and whether or not G knows that p does not locally supervene on the mental states of the members of G. Instead, we argue that what is central to G knowing that (...) p is whether G has an epistemic structure that is functioning appropriately in accord with the action-related purposes of the group, and this structure may include non-agential elements such as devices that retain or process information. We argue that recent objections to non-summative group knowledge given by Jennifer Lackey do not in fact succeed in undermining the view, but do help to clarify the nature of non-summative group knowledge. The main upshot of our response to Lackey’s objections is that groups put their knowledge into action in ways that often differ from how individuals do so, and social epistemologists should be careful to notice these differences, especially insofar as groups often structure themselves by employing various epistemically-relevant devices.

Recent work in judgment and decisionmaking has stressed that institutions, like individuals, often rely on decisionmaking heuristics. But most of the institutional decisionmaking heuristics studied to date are highly firm- and industry-specific. This contrasts to the individual case, in which many heuristics are general-purpose rules suitable for a wide range of decision problems. Are there also general-purpose heuristics for institutional decisionmaking? In this paper, I argue that a number of methods recently developed for decisionmaking under deep uncertainty have a good (...) claim to be understood as general-purpose decisionmaking heuristics suitable for a broad range of institutional decision problems.

The summativists generally analyze group belief in terms of belief of the majority. The non-summativists counterargue that it is possible for a group to believe that p even if “none” of its members believes that p. In doing so, they usually appeal to hypothetical cases in which groups are “structured” groups like committees, research groups, governments, as opposed to “collective” groups like Finns, America, Catholic Church. In this paper, I raise the objection that non-summativist cases involve summativism. While most contemporary (...) objections to non-summativism tend to be rejectionists, i.e., showing that non-summativist cases involve group acceptance rather than group belief, my objection is newfangled in that it grants non-summativist cases group belief but shows that group belief in such cases is majority belief.

Discussions of diversity tend to paint a mixed picture of the practical and epistemic value of diversity. While there are expansive and detailed accounts of the value of cognitive diversity, explorations of identity diversity typically focus on its value as a source or cause of cognitive diversity. The resulting picture on which identity diversity only possesses a derivative practical and epistemic value is unsatisfactory and fails to account for some of its central epistemic benefits. In response, I propose that collective (...) virtue epistemology offers theoretical models that can further our understanding of the benefits of diversity. And I offer a case study to illustrate how this approach could be used to explore the logic of the identity diversity bonus. (shrink)

Many epistemologists have argued that there is some degree of independence between individual and collective reliability (e.g., Kitcher 1990; Mayo-Wilson, Zollman, and Danks 2011; Dunn 2018). The question, then, is: To what extent are the two independent of each other? And in which contexts do they come apart? In this paper, I present a new case confirming the independence between individual and collective reliability optimization. I argue that, in voting groups, optimizing individual reliability can conflict with optimizing collective reliability. This (...) can happen even if various conditions are held constant, such as: the evidence jurors have access to, the voting system, the number of jurors, some independence conditions between voters, and so forth. This observation matters in many active debates on, e.g., epistemic dilemmas, the wisdom of crowds, independence theses, epistemic democracy, and the division of epistemic labour. (shrink)

The purpose of this paper is to illustrate, formally, an ambiguity in the exercise of political influence. To wit: A voter might exert influence with an eye toward maximizing the probability that the political system (1) obtains the correct (e.g. just) outcome, or (2) obtains the outcome that he judges to be correct (just). And these are two very different things. A variant of Condorcet's Jury Theorem which incorporates the effect of influence on group competence and interdependence is developed. Analytic (...) and numerical results are obtained, the most important of which is that it is never optimal--from the point-of-view of collective accuracy--for a voter to exert influence without limit. He ought to either refrain from influencing other voters or else exert a finite amount of influence, depending on circumstance. Philosophical lessons are drawn from the model, to include a solution to Wollheim's "Paradox in the Theory of Democracy". (shrink)

Previous simulation models have found positive effects of cognitive diversity on group performance, but have not explored effects of diversity in demographics (e.g., gender, ethnicity). In this paper, we present an agent-based model that captures two empirically supported hypotheses about how demographic diversity can improve group performance. The results of our simulations suggest that, even when social identities are not associated with distinctive task-related cognitive resources, demographic diversity can, in certain circumstances, benefit collective performance by counteracting two types of conformity (...) that can arise in homogeneous groups: those relating to group-based trust and those connected to normative expectations towards in-groups.

Group agents can act, and they can have knowledge. How should we understand the species of collective action which aims at knowledge? In this paper, I present an account of group inquiry. This account faces two challenges: to make sense of how large-scale distributed activities might be a kind of group action, and to make sense of the kind of division of labour involved in collective inquiry. In the first part of the paper, I argue that existing accounts of group (...) action face problems dealing with large-scale group actions, and propose a minimal alternative account. In the second part of the paper, I draw on an analogy between inquiry and conversation, arguing that work by Robert Stalnaker and Craige Roberts helps us to think about the division of labour. In the final part of the paper I put the accounts of group action and inquiry together, and consider how to think about group knowledge, deep ignorance, and the different kinds of division of labour.
