Since Darwin, the idea of psychological continuity between humans and other animals has dominated theory and research in investigating the minds of other species. Indeed, the field of comparative psychology was founded on two assumptions. First, it was assumed that introspection could provide humans with reliable knowledge about the causal connection between specific mental states and specific behaviors. Second, it was assumed that in those cases in which other species exhibited behaviors similar to our own, similar psychological causes were (...) at work. In this paper. we show how this argument by analogy is flowed with respect to the case of second-order mental states. As a test case, we focus on the question of how other species conceive of visual attention, and in particular whether chimpanzees interpret seeing as a mentalistic event involving internal states of perception, attention, and belief. We conclude that chimpanzees do not reason about seeing in this manner, and indeed, there is considerable reason to suppose that they do not harbor representations of mental states in general. We propose a reinterpretation model in which the majority of the rich social behaviors that humans and other primates share in common emerged long before the human lineage evolved the psychological means of interpreting those behaviors in mentalistic terms. Although humans, chimpanzees, and most other species may be said to possess mental states, humans alone may have evolved a cognitive specialization for reasoning about such states. (shrink)

Simple Heuristics That Make Us Smart invites readers to embark on a new journey into a land of rationality that differs from the familiar territory of cognitive science and economics. Traditional views of rationality tend to see decision makers as possessing superhuman powers of reason, limitless knowledge, and all of eternity in which to ponder choices. To understand decisions in the real world, we need a different, more psychologically plausible notion of rationality, and this book provides it. It is (...) about fast and frugal heuristics--simple rules for making decisions when time is pressing and deep thought an unaffordable luxury. These heuristics can enable both living organisms and artificial systems to make smart choices, classifications, and predictions by employing bounded rationality. But when and how can such fast and frugal heuristics work? Can judgments based simply on one good reason be as accurate as those based on many reasons? Could less knowledge even lead to systematically better predictions than more knowledge? Simple Heuristics explores these questions, developing computational models of heuristics and testing them through experiments and analyses. It shows how fast and frugal heuristics can produce adaptive decisions in situations as varied as choosing a mate, dividing resources among offspring, predicting high school drop out rates, and playing the stock market. As an interdisciplinary work that is both useful and engaging, this book will appeal to a wide audience. It is ideal for researchers in cognitive psychology, evolutionary psychology, and cognitive science, as well as in economics and artificial intelligence. It will also inspire anyone interested in simply making good decisions. (shrink)

Discussions of group knowledge typically focus on whether a group’s knowledge that p reduces to group members’ knowledge that p. Drawing on the cumulative reading of collective knowledge ascriptions and considerations about the importance of the division of epistemic labour, I argue what I call the Fragmented Knowledge account, which allows for more complex relations between individual and collective knowledge. According to this account, a group can know an answer to (...) a question in virtue of members of the group knowing parts of that answer, when the whole answer is available to group-level action. I argue that this account explains a swathe of central cases of group knowledge, as well as explaining some central features of group knowledge. (shrink)

If individual knowledge and justification can be vanquished by epistemic defeaters, then the same should go for group knowledge. Lackey (2014) has recently argued that one especially strong conception of group knowledge defended by Bird (2010) is incapable of preserving how it is that (group) knowledge is ever subject to ordinary mechanisms of epistemic defeat. Lackey takes it that her objections do not also apply to a more moderate articulation of group (...) class='Hi'>knowledge--one that is embraced widely in collective epistemology--and which she does not challenge. This paper argues that given certain background premises that are embraced by orthodox thinking in collectivist epistemology, the more moderate account of group knowledge cannot make sense of either psychological or normative epistemic defeaters. I conclude by offering some suggestions for how the more moderate proposal might avoid this result. (shrink)

In this paper, I introduce the emerging theory of judgment aggregation as a framework for studying institutional design in social epistemology. When a group or collective organization is given an epistemic task, its performance may depend on its ‘aggregation procedure’, i.e. its mechanism for aggregating the group members’ individual beliefs or judgments into corresponding collective beliefs or judgments endorsed by the group as a whole. I argue that a group’s aggregation procedure plays an important role in (...) determining whether the group can meet two challenges: the ‘rationality challenge’ and the ‘knowledge challenge’. The rationality challenge arises when a group is required to endorse consistent beliefs or judgments; the knowledge challenge arises when the group’s beliefs or judgments are required to track certain truths. My discussion seeks to identify those properties of an aggregation procedure that affect a group’s success at meeting each of the two challenges. (shrink)

In this paper we apply social epistemology to mathematical proofs and their role in mathematical knowledge. The most famous modern collaborative mathematical proof effort is the Classification of Finite Simple Groups. The history and sociology of this proof have been well-documented by Alma Steingart (2012), who highlights a number of surprising and unusual features of this collaborative endeavour that set it apart from smaller-scale pieces of mathematics. These features raise a number of interesting philosophical issues, but have received very (...) little attention. In this paper, we will consider the philosophical tensions that Steingart uncovers, and use them to argue that the best account of the epistemic status of the Classification Theorem will be essentially and ineliminably social. This forms part of the broader argument that in order to understand mathematical proofs, we must appreciate their social aspects. (shrink)

In spite of the booming interest in social epistemology, explicit analyses of group knowledge remain rare. Most existing accounts are based on theories of joint intentionality. I argue that this approach, though not without merit or useful applications, is inadequate both when it comes to accounting for actual group knowledge attributions and for purposes of meliorative social epistemology. As an alternative, I outline a liberal, de-intellectualized account, which allows for the complex distribution of epistemic states typical (...) of most real-world collectives, and makes minimal requirements as to the psychological underpinnings of collective states of knowing and the formal features of groups. The account is inspired by theories of distributed and extended cognition. It is guided by the principle that we should use the same standard when dealing with social and individual epistemology. Careful attention to what is normally required—and, in particular, not required—for attributing knowledge to individuals lends support the more liberal view. (shrink)

The main task of the present paper is to investigate the nature of collective knowledge and discuss what kind of justificatory aspects are involved in it to discuss it from collective belief. The central kind of collective knowledge investigated is normatively binding knowledge attributed to a social group. A distinction is made between natural knowledge and constitutive knowledge related to social (especially institutional) matters. In the case of the latter kind of knowledge, in (...) contrast to the former kind, justification and the criteria of justification are purely social. Knowledge is regarded as a primitive, irreducible notion that accordingly does not fall prey to Gettier-type paradoxes. (shrink)

Social epistemology is a many-splendored subject. Different theorists adopt different approaches and the options are quite diverse, often orthogonal to one another. The approach I favor is to examine social practices in terms of their impact on knowledge acquisition . This has at least two virtues: it displays continuity with traditional epistemology, which historically focuses on knowledge, and it intersects with the concerns of practical life, which are pervasively affected by what people know or don't know. In making (...) this choice, I am not blind to the allure of alternative approaches. In this paper I explain and motivate the knowledge-centered approach by contrasting it with a newly emerging alternative that has a definite appeal of its own. According to this alternative, the chief dimension of social epistemological interest would be rationality rather than knowledge. (shrink)

A prominent question in social epistemology concerns the epistemic profile of groups. While inflationists and deflationists agree that groups are fit to constitute knowers, they disagree about whether group knowledge is reducible to knowledge of their individual members. This paper develops and defends a weak inflationist view according to which some, but not all, group knowledge is over and above any knowledge of their members. This view sits between the deflationist view that all (...) class='Hi'>group knowledge is reducible to individual knowledge, and the strong inflationist view that some such knowledge even fails to supervene on features of individuals. Thus, some group knowledge is irreducible, but all such knowledge is anchored in, and so doesn't float freely from, individual features. (shrink)

In this paper we formalize an approach to knowledge that we call Interrogative Epistemology, in the spirit of Hintikka’s “interrogative model” of knowledge. According to our approach, an agent’s knowledge is shaped and limited by her interrogative agenda. The dynamic correlate of this postulate is our Selective Learning principle: the agent’s agenda limits her potential for knowledge-acquisition. Only meaningful information, that is relevant to one’s issues, can really be learnt. We use this approach to propose a (...) new perspective on group knowledge, understood in terms of the epistemic potential of a group of agents: the knowledge that the group may come to possess in common after all members share their individual information. We argue that the standard notions of group knowledge studied in the literature, ranging from distributed knowledge to common knowledge, do not give us a good measure of a group’s epistemic potential. Common knowledge is too weak and too “static”, focusing on what the agents can coordinate upon only based on their actual, current knowledge, thus disregarding testimonial knowledge. In contrast, the concept of distributed knowledge is too strong, being based on the assumption that agents can completely internalize all the testimonial evidence received from others, irrespective of the limitations posed by their own interrogative agendas. We show that a group’s true epistemic potential typically lies in between common knowledge and distributed knowledge. We propose a logical formalization of these concepts, which comes together with a complete axiomatization, and we use this setting to explain both the triumphs and the failures of collective knowledge, treating examples that range from “collective scientific knowledge” [14, 35, 43] to the so-called “curse of the committee”.

A view growing in popularity in the current philosophical literature is that the purpose of knowledge attributions is to identify or flag good informants. Such a thesis has its origin in the work of Bernard Williams and Edward Craig. Williams, for instance, claims that the central point of the concept of knowledge is “to find somebody who is a source of reliable information about something” (1973, p.

Jesper Kallestrup has provided an insightful response to our paper, “Epistemic Structure in Non-Summative Social Knowledge”. Kallestrup identifies some important issues pertaining to our non-summative, non-supervenient account of group knowledge which we did not address in our original paper. Here, we develop our view further in light of Kallestrup’s helpful reply.

Jennifer Lackey has recently presented a new and lucid analysis of the notion ofjustified group belief, i.e. a set of individually necessary and jointly sufficient conditions for a group to justifiedly believe some proposition. In this paper, however, I argue that theanalysansshe proposes is too narrow: one of the conditions she takes to be necessary for justified group belief is not necessary. To substantiate this claim, I present a potential counterexample to Lackey's analysis where a group (...) knows and thus justifiedly believes some proposition but there is no single group member who actually believes that proposition. I close by defending the example against the objection that the group in question does notknowbut is at mostin a positionto know the target proposition. (shrink)

Endorsing the idea of group knowledge seems to entail the possibility of group belief as well, because it is usually held that knowledge entails belief. It is here studied whether it would be possible to grant that groups can have knowledge without being committed to the controversial view that groups can have beliefs. The answer is positive on the assumption that knowledge can be based on acceptance as well as belief. The distinction between belief (...) and acceptance can be seen as a refinement of the ordinary language concept of belief, and it may be useful in understanding the nature of epistemic justification and classifying various types of epistemic subjects.

I connect two increasingly popular ideas in social epistemology—group knowledge and epistemic extension—both departures from mainstream epistemological tradition. In doing so, I generate a framework for conceptualizing and organizing contemporary epistemology along several core axes. This, in turn, allows me to delineate a largely unexplored frontier in group epistemology. The bulk of extant work in group epistemology can be dubbed intra-group epistemology: the study of epistemically salient happenings within groups. I delineate and attempt to motivate (...) what I dub inter-group epistemology: the study of epistemically salient happenings between groups and other subjects and entities. (shrink)

Under what conditions is a group belief resulting from deliberation constitutive of group knowledge? What kinds of competences must a deliberating group manifest when settling a question so that the resulting collective belief can be considered group knowledge? In this paper, we provide an answer to the second question that helps make progress on the first question. In particular, we explain the epistemic normativity of deliberation-based group belief in terms of a truth norm (...) and an evidential norm, introduce a virtue-reliabilist condition on deliberative group knowledge, and provide an account and a taxonomy of the types of group competences that are necessary for this type of collective knowledge.

The aim of this paper is to relate two trending topics in contemporary epistemology: the discussion of group knowledge and the discussion of knowledge-first approach. In social epistemology no one has seriously applied and developed Williamson’s theory of knowledge-first approach to the case of group knowledge yet. For example, scholars of group knowledge typically assume that knowledge is analyzed in terms of more basic concepts, such as group belief or acceptance, (...) group justification, and so on. However, if Williamson’s theory of knowledge is correct, these are not good analyzes for understanding group knowledge. For, in such framework, knowledge is not analyzed in terms of belief and justification, and the same should apply to group knowledge. Thus, we propose to analyze which consequences Williamson’s theory has for social epistemology, namely for an understanding of group knowledge. The questions that will guide this article are the following: What is a knowledge-first approach to group knowledge? And what does a knowledge-first approach teach us with regard to one of the most pressing issues of social epistemology, namely the dispute between summativists and non-summativists accounts of groups? We claim that a knowledge-first account of group knowledge can be offered and that it favors non-summativism. (shrink)

Recently, Margaret Gilbert has argued that it appears that the wisdom of a society impinges, greatly, on its freedom. In this article, I show that Gilbert’s “negative argument” fails to be convincing. On the other hand, there are important lessons, particularly for democratic theory, that can be by looking carefully, and critically, at her argument. This article will proceed as follows. First, I present Gilbert’s argument. Next, I criticize her understanding of freedom, and then, using arguments from Christopher McMahon, criticize (...) her understanding of a wise society. Finally, I discuss how what has been said can inform how one should think about democratic theory. (shrink)

In this paper, we propose a dynamic epistemic framework to capture the knowledge evolution in multi-agent systems where agents are not able to observe. We formalize multi-agent conformant planning with group knowledge, and reduce planning problems to model checking problems. We prove that multi-agent conformant planning with group knowledge is Pspace -complete on the size of dynamic epistemic models. We also consider the alternative Kripke semantics, and show that for each Kripke model with perfect recall (...) and no miracles, there is an equivalent dynamic epistemic model and vice versa.

Does geometry constitues a core set of intuitions present in all humans, regarless of their language or schooling ? We used two non verbal tests to probe the conceptual primitives of geometry in the Munduruku, an isolated Amazonian indigene group. Our results provide evidence for geometrical intuitions in the absence of schooling, experience with graphic symbols or maps, or a rich language of geometrical terms.

Kristina Rolin and Brad Wray agree with an increasing number of epistemologists that knowledge can sometimes be attributed to a group and to none of its individual members. That is, collective knowledge sometimes obtains. However, Rolin charges Wray with being too restrictive about the kinds of groups to which he attributes collective knowledge. She rejects Wray’s claim that only scientific research teams can know while the general scientific community cannot. Rolin forwards a ‘default and challenge’ account (...) of epistemic justification toward her argument that even the general scientific community can know because it’s sometimes the general scientific community, and none of its individual members, that attains epistemic justification. I argue that Rolin faces a dilemma: either she must herself be more restrictive about the kinds of groups to which she attributes collective knowledge or she must concede the general claim that collective knowledge obtains at all.

In the paper, I distinguish the bottom-up strategy and the intentional stance strategy of analyzing group intentional states, and show that the thesis of distributed group subject of knowledge could be accommodated by either of them. Moreover, I argue that when combined with virtue reliabilism the thesis satisfactorily explains the phenomenon of group knowledge. To justify my argument, in the second part of the paper, I distinguish two accounts of justification pointing to conditions of (...) class='Hi'>group knowledge. The first, which I call the belief-centered approach to group intentional states, determines the concept of group belief and group justificatory reason. The second, the process-centered approach represented by S. Orestis Palermos, employs the theory of virtue reliabilism and focuses on the group knowledge-conducive process. In the paper, I argue in favor of the latter as the internalism associated with the former appears to lack sufficient explanatory power. The theory of virtue epistemology runs into considerable difficulties when trying to deal with an extended epistemic subject composed of one individual and her cognitive artifact. In the two last parts of the paper, I consider the most important difficulties and argue that these obstacles are overcome once one adopts an approach combining virtue epistemology and the thesis of distributed group epistemic subject.

This paper investigates how participants in cross-functional project groups use a formal work method in their sense making when dealing with the complexity of innovative work, especially in its inventive phase. The empirical basis of the paper is a prospective case study in which three project groups in three different companies are followed as they try to frame and solve their innovation tasks consisting in problems of a relatively general and vague character. The data are analyzed by means of a (...) modified version of the principles of grounded theory. This means that the lessons drawn from the empirical data are guided by a relational sense making perspective in which the formal method used by the participants is seen as a technological artifact. Among the lessons learned by using this frame of reference are that a formal method may be seen as an entity with a meaning depending on the relations it is embedded in; as an enacted cue for interpretation and action; and as a non-human actor. Compared to the tradition of organizational development, these lessons represent an alternative conception of the implementation of a work method and illuminate prevailing notions about the importance of improvisation in innovation.

Health information technology in hospitals can be approached as a tool to reduce health care costs and improve hospital efficiency and profitability, increase the quality of healthcare services, and make the transition to patient-centered healthcare. A hospital’s efficiency and profitability depends on linking IT with the knowledge and motivation of medical personnel. It is important to design and execute a knowledge management strategy as a part of the implementation of IT in hospital management. A Diagnosis-Related Groups system was (...) introduced in Poland in 2008 as a basis for settlements between hospitals and the National Health Fund. The importance and role of a DRG system in management of healthcare entities was emphasized based on a survey of medical professionals from two hospitals in the Lubelskie province. The goal of a survey is to assess the knowledge of medical professionals about the DRG system and how the medical personnel uses the DRG system in order to achieve the strategic goals of the organization. A newly developed survey was used to assess the medical personnel’s knowledge of DRG, using 12 closed and 5 open questions. The survey was conducted on 160 medical employees from two hospitals in the Lubelskie province. In conclusion, medical personnel’s DRG knowledge unambiguously contributes to reducing hospital costs and increasing profitability. The DRG related knowledge enables personnel to obtain value from data by applying DRG data-driven decisions. (shrink)

An essential aspect of forming representations of social groups is to recognize socially relevant attributes licensed by the group membership. Because knowledge of cultural practices tends to be transmitted through social contact within social groups, it is one of the fundamental attributes shared among members of a social group. Two experiments explored whether 5‐ and 6‐year‐olds selectively attribute shared cultural knowledge on the basis of group membership of agents. Using novel social groups, children were introduced (...) to one target agent and two other agents, one of which belonged to the same group as the target and one belonged to a different group. Children were then asked who would know or like same things as the target agent. The results showed that children expect group members to know the same songs, whereas they do not necessarily expect them to like the same songs or know the same generic facts. These findings suggest that children are remarkably selective in the attributions they make based on social group membership and from early on, they expect social group membership and cultural knowledge to be closely linked.

We study shared intentions in what we call “loose groups”. These are groups that lack a codified organizational structure, and where the communication channels between group members are either unreliable or not completely open. We start by formulating two desiderata for shared intentions in such groups. We then argue that no existing account meets these two desiderata, because they assume either too strong or too weak an epistemic condition, that is, a condition on what the group members know (...) and believe about what the others intend, know, and believe. We propose an alternative, pooled knowledge, and argue that it allows formulating conditions on shared intentions that meet the two desiderata. (shrink)

Epistemic paternalism occurs when a decision is made for an agent which helps them arrive at the truth, though they didn’t consent to that decision (and sometimes weren’t even aware of it). Common defenses of epistemic paternalism claim that it can help promote positive veritistic results. In other words, epistemic paternalism is often good for inquiry. I argue that there is often a better alternative available to epistemic paternalism in the form of what I call Open Group Inquiry. I (...) then examine how Open Group Inquiry can be applied to cases of religious inquiry, while noting that epistemic paternalism is impermissible in cases of general religious inquiry. I argue that in the case of religious inquiry, there are serious questions about what constitutes evidence along with how to evaluate it. Rather than posing a particular worry for Open Group Inquiry, I suggest these questions pose a problem for religious inquiry in general. I conclude that while it very much matters how concepts like religious knowledge, religious faith, scepticism, etc., are defined, these considerations may well pave the way for a novel argument for religious scepticism.

This article explores the management and organisational context for capturing and retaining knowledge transferred through the design process. It is widely acknowledged that our ability to successfully organise and transfer design knowledge is dependant upon the context in which it is situated. However the knowledge generated through the creative process is often viewed from the perspective of the artefact rather the process itself. An understanding of the socially complex knowledge-based resources operating within design groups could enhance (...) competitiveness and organisational development. Yet, a systematic literature review of leading design and educational management journals found limited empirical evidence that shed light on the influence of knowledge management on design group performance. The article addresses this gap in the literature. Based on two in-depth case studies with interior design companies implementing new digital asset management systems over a 2-year period, the paper explores the findings in relation to design practice and policy, alongside implications for the contribution of the creative industries to the knowledge economy.

Much scientific research is characterized by a high degree of multidisciplinarity and interdependence between the experts. In these cases research may be described as a group activity, and as such analysed in terms of the intentions of the participants. In this paper I apply Bratman's notion of shared intentionality to explain the relations between social and epistemic elements in groups with a truth-oriented common goal. I argue that in truth-oriented activities the disposition to help – which is a constitutive (...) part of Bratman's notion of shared intentionality – takes the form of a commitment not to lie, and that mutual knowledge of this commitment gives the members an entitlement to rely on other members' testimonies. Thus, in truth-oriented group activities, common knowledge of the disposition toward mutual support gives epistemic relevance to cooperation. Scientific research is shaped by the coexistence of social and epistemic elements: social relations influence knowledge attributions, and the epistemic goal of the activity confers a particular character to these relations.

Public announcement logic is an extension of epistemic logic with dynamic operators that model the effects of all agents simultaneously and publicly acquiring the same piece of information. One of the extensions of PAL, group announcement logic, allows quantification over announcements made by agents. In GAL, it is possible to reason about what groups can achieve by making such announcements. It seems intuitive that this notion of coalitional ability should be closely related to the notion of distributed knowledge, (...) the implicit knowledge of a group. Thus, we study the extension of GAL with distributed knowledge, and in particular possible interaction properties between GAL operators and distributed knowledge. The perhaps surprising result is that, in fact, there are no interaction properties, contrary to intuition. We make this claim precise by providing a sound and complete axiomatisation of GAL with distributed knowledge. We also consider several natural variants of GAL with distributed knowledge, as well as some other related logic, and compare their expressive power. (shrink)

Originally published in 1969. Since the seventeenth century the kind of knowledge afforded by mathematical physics has come more and more to furnish mankind with an ideal for all knowledge. The ideal also carries with it a new conception of the nature of things: all things whatsoever are held to be intelligible ultimately in terms of the laws of inanimate nature. This reductionist formula can be overcome only by the fundamental rethinking of our philosophical premises. To contribute towards (...) thsi rethinking was the aim of the Study Group at whose meetings this collection originated. The essayists come from a wide range of disciplines but all want to address the conflict in our culture. The first part consists of discussions of various fundamental problems in the sciences. There are essays on the inter-relation of physics and psychology, on the possible reduction of biology to physics and chemistry, on new approaches to experimental psychology, against the possibility of giving a purely ‘factual’ account of social and political life, and for a fundamental reform of our concept of responsibility. The second section of the book suggests lines of philosophical inquiry which might help to resolve the epistemological and ethical problems arising at the foundations of physics, biology, psychology and the social sciences.
