Collective Epistemology

During the past decades, research collaboration between researchers from different disciplines has become more frequent. However, there is a need to look into the generic modalities and challenges. The article explores a series of potential obstructions to cross-disciplinary collaboration of methodological and epistemological nature. Furthermore, a number of contextual, inhibiting factors are outlined. As means of overcoming the obstacles, the importance of mutual knowledge, allocation of adequate time and conducive research management is emphasised. New teams may benefit from tutoring by (...) facilitators, who can help to make problem areas explicit and negotiate solutions. Owing to the training background of the author, most of the examples are drawn from the interface between biomedicine/natural science and applied medical anthropology. However, the issues raised basically apply to all sorts of cross-disciplinary research collaboration in various combinations. (shrink)

In this paper, the authors argue for two main claims: first, that the epistemic results of group deliberation can be superior to those of individual inquiry; and, second, that successful deliberative groups depend on individuals exhibiting deliberative virtues. The development of these group-deliberative virtues, the authors argue, is important not only for epistemic purposes but political purposes, as democracies require the virtuous deliberation of their citizens. Deliberative virtues contribute to the deliberative synergy of the group, not only in terms of (...) improving the quality of the group's present decisions, but also improving the background conditions for continued group deliberation. The authors sketch a preliminary schedule of these group-deliberative virtues modelled on Aristotle's conception of virtue as the mean between two extreme vices. The virtues discussed in this article include deliberative wit, friendliness, empathy, charity, temperance, courage, sincerity, and humility. (shrink)

Why is the average quality of research in open science so high? The answer seems obvious. Science is highly competitive, and publishing high quality research is the way to rise to the top. Thus, researchers face strong incentives to produce high quality work. However, this is only part of the answer. High quality in science, after all, is what researchers in the relevant field consider to be high quality. Why and how do competing researchers coordinate on common quality standards? I (...) argue that, on the methodological level, science is a dynamic beauty contest. (shrink)

Throughout his work on the rationality of epistemic dependence, John Hardwig makes the striking observation that he believes many things for which he possesses no evidence (1985, 335; 1991, 693; 1994, 83). While he could imagine collecting for himself the relevant evidence for some of his beliefs, the vastness of the world and constraints of time and individual intellect thwart his ability to gather for himself the evidence for all his beliefs. So for many things he believes what others tell (...) him, as we all do. Epistemic dependence is the responsible choice, he argues, because he can be reasonably sure that those on whom he depends know more about the subject than he does. Epistemic dependence on experts is a smarter bet than epistemic autonomy: after all, Hardwig reasons, “if I were to pursue epistemic autonomy across the board, I would succeed in holding relatively uninformed, unreliable, crude, untested, and therefore irrational beliefs” (1985, 340) [...] In this paper I argue against what I call Hardwig’s no-evidence thesis: that knowledge and belief based on testimony are knowledge and belief for which the knower possesses no evidence. Against the no-evidence thesis, I propose we recognize that layperson B’s good reason to believe that expert A has good reason to believe proposition p constitutes evidence for B for p. I argue that the reasons Hardwig gives for the no-evidence thesis are inconclusive at best; at worst the no-evidence thesis coupled with his recognition of expert interdependence exposes him to recent criticisms by Stella Gaon and Stephen Norris. By rejecting the no-evidence thesis, we can recognize with Hardwig the importance of expert epistemic interdependence while avoiding the paradoxical implications of his position. (shrink)

Recently, several scholars have argued that scientists can accept scientific claims in a collective process, and that the capacity of scientific groups to form joint acceptances is linked to a functional division of labor between the group members. However, these accounts reveal little about how the cognitive content of the jointly accepted claim is formed, and how group members depend on each other in this process. In this paper, I shall therefore argue that we need to link analyses of joint (...) acceptance with analyses of distributed cognition. To sketch how this can be done, I shall present a detailed case study, and on the basis of the case, analyze the process through which a group of scientists jointly accept a new scientific claim and at a later stage jointly accept to revise previously accepted claims. I shall argue that joint acceptance in science can be established in situations where an overall conceptual structure is jointly accepted by a group of scientists while detailed parts of it are distributed among group members with different areas of expertise, a condition that I shall call a heterogeneous conceptual consensus. Finally, I shall show how a heterogeneous conceptual consensus can work as a constraint against scientific change and address the question how changes may nevertheless occur. (shrink)

Originally titled “Institutional, Group, and Individual Virtue,” this was my paper for an Invited Symposium on "Intersections between Social, Feminist, and Virtue Epistemologies," APA Pacific Division Meeting, April 2011, San Diego. -/- Abstract: This paper examines recent research on individual, social, and institutional virtues and vices; the aim is to explore and make proposals concerning their inter-relationships, as well as to highlight central questions for future research with the study of each. More specifically, the paper will focus on how these (...) studies can be approached in a systematic way such that it contributes to greater convergence between virtue theory, feminist epistemology, and social epistemology. To this end the paper develops a model of responsibility qua diachronic (longitudinal) assessment of the inquiry-directed agential habits (motivations, activities, and strategies), while explaining the place of this model within a broader, 15-point proposed “Responsibilist” research program.

Abstract The article sketches a theoretical model which explains how it is possible that fundamentalist beliefs can emerge as a result of an individual rational adaptation to the context of special living conditions. The model is based on the insight that most of our knowledge is acquired by trusting the testimony of some kind of authority. If a social group is characterized by a high degree of mistrust towards the outer society or other groups, then the members of this group (...) will rely solely on the authorities of their own group for their acquisition of knowledge. In this way they can adopt a corpus of beliefs which may seem absurd from an external point of view. However, they may be locked in a “fundamentalist equilibrium” in which particularistic trust, common sense plausibility, epistemic seclusion, social isolation and fundamentalist beliefs are mutually reinforcing - and in which individuals who adopt the “fundamentalist truths” of their group do not behave more irrationally than individuals in an open society who accept the “enlightened” worldview of their culture.

The use of intuition and emotion in reasoning or in building hypothesis has been discussed through varied approaches within many disciplines. Emanuele Bardone provides new insights into these issues, such as the idea of human cognition as a chance-seeking system. This perspective creates a new framework when considering the decision-making and problem solving challenges. One of the key concepts that Bardone discusses at length is affordances, the relation of affordances to abduction and to the eco-cognitive niche. Worth mentioning are also: (...) niche construction and the notion of humans as ecological engineers. All these concepts use, and build upon, the idea of distributed cognition. (shrink)

According to a common view, prejudice always involves some form of epistemic culpability, i.e., a failure to respond to evidence in the appropriate way. I argue that the common view wrongfully assumes that prejudices always involve universal generalizations. After motivating the more plausible thesis that prejudices typically involve a species of generic judgment, I show that standard examples provide no grounds for positing a strong connection between prejudice and epistemic culpability. More generally, the common view fails to recognize the extent (...) to which prejudices are epistemically insidious: once they are internalized as background beliefs, they quite reasonably come to control the assessment and interpretation of new evidence. This property of insidiousness helps explain why prejudices are so recalcitrant to empirical counterevidence and also why they are frequently invisible to introspective reflection. (shrink)

Linda Zagzebski's "Epistemic Authority" (Oxford University Press, 2012) brings together issues in social epistemology with topics in moral and political philosophy as well as philosophy of religion. In this paper I criticize her discussion of self-trust and rationality, which sets up the main argument of the book; I consider how her view of authority relates to some issues of epistemic authority in testimony; and I raise some concerns about her treatment of religious epistemology and religious authority in particular.

The aim of John Searle’s philosophy of society is to provide a foundation for the social sciences. Arguing that the study of social reality needs to be based on a philosophy of language, Searle claims that sociology has little to offer since no sociologist ever took language seriously. Attacking Durkheim head-on, Searle not only claims that Durkheim’s project differs from his own but also that Durkheim’s sociology has serious shortcomings. Opposing Searle, this paper argues that Durkheim’s account of social reality (...) is still viable and that Searle’s attack backfires on his own theoretical project. (shrink)

Formal models for group knowledge can help philosophers gain additional insight into the ramifications of the philosophical concepts that they propose by clarifying the abstract properties of these concepts and their relationship to alternative proposals. To date, however, formal treatments of group knowledge have remained largely disjointed from the related philosophical discussions and are therefore of minimal interest to philosophers. In this thesis, I attempt to bridge this gap by proposing a formal definition of group knowledge that I call collective (...) knowledge. Collective knowledge is distributed knowledge about common questions and typically lies between common knowledge and full distributed knowledge. It includes two epistemic properties that make it more aligned with philosophical concepts of group knowledge, and that are not modeled by the standard notions from formal epistemology. The first property is that all knowledge is in terms of questions, interpreted as distinctions that define an agent's conceptual framework. The second property is that group knowledge implies an epistemic group, which is a group of agents tied together through mutual interest in each other's knowledge and questions. To model epistemic groups and collective knowledge, I introduce new Kripke models that I refer to as epistemic group models. I then present an axiomatic system for the logic of collective knowledge and prove that it is sound and complete with respect to these new models. As such, I hope to have provided a good first step towards a formal definition of group knowledge that can help advance the philosophical discussion on group knowledge. (shrink)

Generally, rational decision-making is conceived as arriving at a decision by a correct application of the rules of logic and statistics. If not, the conclusions are called biased. After an impressive series of experiments and tests carried out in the last few decades, the view arose that rationality is tough for all, skilled field experts not excluded. A new type of planner's counsellor is called for: the normative statistician, the expert in reasoning with uncertainty par excellence. To unravel this view, (...) the paper explores a specific practice of clinical decision-making, namely Evidence-Based Medicine. This practice is chosen, because it is very explicit about how to rationalize practice. The paper shows that whether a decision-making process is rational cannot be assessed without taking into account the environment in which the decisions have to be taken. To be more specific, the decision to call for new evidence should be rational too. This decision and the way in which this evidence is obtained are crucial to validate the base rates. Rationality should be model-based, which means that not only the isolated decision-making process should take a Bayesian updating process as its norm, but should also model the acquisition of evidence (priors and tests results) as a rational process.

The issue of knowing what it means for a group to have collective beliefs is being discussed more and more in contemporary philosophy of the social sciences and philosophy of mind. Margaret Gilbert’s reconsideration of Durkheim’s viewpoint in the framework of the plural subject’s account is one of the most famous. This has implications in the history and the sociology of science—as well asin the history and sociology of philosophy—although Gilbert only outlined them in the former fields and said nothing (...) about the latter. Symmetrically but independently, a historian of science, Mara Beller, has recently challenged Kuhn’s conception of the role of consensus in sciences in a brilliant analysis by carefully studying the history of Copenhagen School of Quantum Mechanics. Not only does she show the role of disagreement and controversies (doubting whether there was any collective belief characteristic in this group of physicists), but she even shakes up the very idea of individual beliefs. Each scientist (Heisenberg, Bohr, etc.) could be seen as divided into several selves. This paper contends that these two conceptions open important new horizons in several domains, especially if they are linked together. The paper assesses this claim in the light of empirical examples like the Vienna Circle, Copenhagen School, and, eventually, Cartesian philosophy. Key Words: plural subject • polyphony • collective briefs • Cartesian argumentation. (shrink)

The Puzzle of the Hats is a puzzle in social epistemology. It describes a situation in which a group of rational agents with common priors and common goals seems vulnerable to a Dutch book if they are exposed to different information and make decisions independently. Situations in which this happens involve violations of what might be called the Group-Reflection Principle. As it turns out, the Dutch book is flawed. It is based on the betting interpretation of the subjective probabilities, but (...) ignores the fact that this interpretation disregards strategic considerations that might influence betting behavior. A lesson to be learned concerns the interpretation of probabilities in terms of fair bets and, more generally, the role of strategic considerations in epistemic contexts. Another lesson concerns Group-Reflection, which in its unrestricted form is highly counter-intuitive. We consider how this principle of social epistemology should be re-formulated so as to make it tenable. (shrink)

Groups engage in epistemic activity all the time--whether it be the active collective inquiry of scientific research groups or crime detection units, or the evidential deliberations of tribunals and juries, or the informational efforts of the voting population in general--and yet in philosophy there is still relatively little epistemology of groups to help explore these epistemic practices and their various dimensions of social and philosophical significance. The aim of this book is to address this lack, by presenting original essays in (...) the field of collective epistemology, exploring these regions of epistemic practice and their significance for Epistemology, Political Philosophy, Ethics, and the Philosophy of Science.

The quest to foretell the future is omnipresent in human affairs. A potential solution to this epistemological conundrum has emerged through mass collaboration. Motored by the Internet, prediction markets allow a multitude of individuals to assume a stake in a security whose value is tied to a future event. The resulting prices offer a continuously updated probability estimate of the event actually taking place. This paper gives a survey of prediction markets, their history, mechanics, uses, and theoretical foundation. We also (...) review the literature surrounding their efficacy. Though there are shortcomings with prediction markets, as well as practical constraints, they hold out the prospect of improving the quality of organizational decisions and increasing the level of participation in the deliberative process. We also note that lessons can be drawn from these markets to guide the epistemological practices of disciplines and inquiries in which empirical methods are difficult to apply. (shrink)

Christian List and Philip Pettit argue that groups of people can be agents – beings that believe, desire and act. Their account combines a non-reductive realist view of group attitudes, on which groups literally have attitudes that cannot be analyzed in terms of the attitudes of their members, with methodological individualism, on which good explanations of group-level phenomena should not posit forces above individual attitudes and behaviors. I then discuss the main normative conclusion that LP draw from the claim that (...) group agents exist: that we ought morally to grant legal rights and responsibilities to group agents, but that group rights should be more limited than individual rights. I argue that when it comes to the fitness of group agents to bear legal rights and responsibilities, LP can draw support from nonreductionist views elsewhere, particularly in the philosophy of mind. I raise some objections to LP's views about the value of granting legal rights and responsibilities to group agents. (shrink)

This paper addresses the problem of judgment aggregation in science. How should scientists decide which propositions to assert in a collaborative document? We distinguish the question of what to write in a collaborative document from the question of collective belief. We argue that recent objections to the application of the formal literature on judgment aggregation to the problem of judgment aggregation in science apply to the latter, not the former question. The formal literature has introduced various desiderata for an aggregation (...) procedure. Proposition-wise majority voting emerges as a procedure that satisfies all desiderata which represent norms of science. An interesting consequence is that not all collaborating scientists need to endorse every proposition asserted in a collaborative document. (shrink)

This paper explores two non-standard supermajority rules in the context of judgment aggregation over multiple logically connected issues. These rules set the supermajority threshold in a local, context sensitive way—partly as a function of the input profile of opinions. To motivate the interest of these rules, I prove two results. First, I characterize each rule in terms of a condition I call ‘Block Preservation’. Block preservation says that if a majority of group members accept a judgment set, then so should (...) the group. Second, I show that one of these rules is, in a precise sense, a judgment aggregation analogue of a rule for connecting qualitative and quantitative belief that has been recently defended by Hannes Leitgeb. The structural analogy is due to the fact that Leitgeb sets thresholds for qualitative beliefs in a local, context sensitive way—partly as a function of the given credence function. (shrink)

List and Pettit's Group Agency is an extremely important book, spearheading a new wave of work on the metaphysics, epistemology and ethics of group agents. In this article, I focus on the epistemological thread in their discussion. After introducing the apparatus they use in analyzing the epistemic performance of groups, I criticize some elements and point to some ways in which the very same apparatus could be redirected to address them.

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 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)

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.

By taking the collective character of scientific research seriously, some philosophers have claimed that scientific knowledge is indeed collective knowledge. However, there is little clarity on what exactly is meant by collective knowledge. In this article, I argue that there are two notions of collective knowledge that have not been well distinguished: irreducibly collective knowledge (ICK) and jointly committed knowledge (JCK). The two notions provide different conditions under which it is justified to ascribe knowledge to a group. It is argued (...) that ICK and JCK need to be approached independently, each of which can shed light on different aspects of science, knowledge production, and acceptance. (shrink)

I use the case of religious belief to argue that communal institutions are crucial to successfully transmitting knowledge to a broad public. The transmission of maximally counterintuitive religious concepts can only be explained by reference to the communities that sustain and pass them on. The shared life and vision of such communities allows believers to trust their fellow adherents. Repeated religious practices provide reinforced exposure while the comprehensive and structured nature of religious worldviews helps to limit distortion. I argue that (...) the phenomenon of theological incorrectness noted by many cognitive scientists of religion is not as worrisome as it may appear. Believers may be employing models that are good enough for practical knowledge, as much of the relevant sociological evidence suggests. Further, communities can help us both in acquiring our initial beliefs and in correcting our errors. (shrink)

Offers a vital, unique and agenda-setting perspective for the field of social epistemology – the philosophical basis for prescribing the social means and ends for pursuing knowledge.

In the tradition of justified true belief theory, I provide an epistemic responsibility-based philosophical analysis of collective knowledge which is both coherentist and reliabilist.

Epistemic paternalism is the thesis that in some circumstances we are justified in interfering with the inquiry of another for their own epistemic good without consulting them on the issue. In this paper, I address the issue of who is rationally entitled to undertake paternalistic interferences, and in virtue of which features one has this entitlement. First, I undermine the view according to which experts are the most apt people to act as paternalist interferers. Then, I argue 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, I offer a virtue-based account of paternalist interferers and show how it can apply to cases in which the interferer is a group or an institution. (shrink)

One of Thomas Kuhn's profoundest arguments is introduced in the 1970 “Postscript” to The Structure of Scientific Revolutions . Kuhn is discussing the idea of a “disciplinary matrix” as a more adequate articulation of the “paradigm” notion he'd introduced in the first, 1962, edition of his famous work . He notes that one “element” of disciplinary matrices is likely to be common to most or even all such matrices, unlike the other elements which serve to distinguish specific disciplines and sub-disciplines (...) from one another. This is the element which he calls “values”, which, as he notes , being common to a number of otherwise distinct disciplinary matrices, “do much to provide a sense of community to natural scientists as a whole”. On the other hand, they also do much, and crucially in Kuhn's view, to promote and sustain a healthy diversity among the practitioners who share any specific disciplinary matrix. In particular, Kuhn claims that “individual variability in the application of shared values may serve functions essential to science.”. (shrink)

Our ability for scientific reasoning is a byproduct of cognitive faculties that evolved in response to problems related to survival and reproduction. Does this observation increase the epistemic standing of science, or should we treat scientific knowledge with suspicion? The conclusions one draws from applying evolutionary theory to scientific beliefs depend to an important extent on the validity of evolutionary arguments (EAs) or evolutionary debunking arguments (EDAs). In this paper we show through an analytical model that cultural transmission of scientific (...) knowledge can lead toward representations that are more truth-approximating or more efficient at solving science-related problems under a broad range of circumstances, even under conditions where human cognitive faculties would be further off the mark than they actually are.

I argue that scientific knowledge is collective knowledge, in a sense to be specified and defended. I first consider some existing proposals for construing collective knowledge and argue that they are unsatisfactory, at least for scientific knowledge as we encounter it in actual scientific practice. Then I introduce an alternative conception of collective knowledge, on which knowledge is collective if there is a strong form of mutual epistemic dependence among scientists, which makes it so that satisfaction of the justification condition (...) on knowledge ineliminably requires a collective. Next, I show how features of contemporary science support the conclusion that scientific knowledge is collective knowledge in this sense. Finally, I consider implications of my proposal and defend it against objections. (shrink)
