Jennifer Lackey presents a ground-breaking exploration of the epistemology of groups, and its implications for group agency and responsibility. She argues that group belief and knowledge depend on what individual group members do or are capable of doing, while being subject to group-level normative requirements.

We often talk about groups believing, knowing, and testifying. For instance, we ask whether the Bush Administration had good reasons for believing that Saddam Hussein had weapons of mass destruction, or whether BP knew that its equipment was faulty before the oil spill in the Gulf of Mexico. Epistemic claims of this sort often have enormously significant consequences, given the ways they bear on the moral and legal responsibilities of collective entities. Despite the importance of these epistemic claims, there has been surprisingly little philosophical work shedding light on these phenomena, their consequences, and the broader implications that follow for epistemology in general. Essays in Collective Epistemology aims to fill this gap in the literature by bringing together new papers in this area by some of the leading figures in social epistemology. The volume is divided into four parts and contains ten articles written on a range of topics in collective epistemology. All of the papers focus on fundamental issues framing the epistemological literature on groups, and offer new insights or developments to the current debates: some do so by providing novel examinations of the epistemological relationship that groups bear to their members, while others point to new, cutting edge approaches to theorizing about concepts and issues related to collective entities. Anyone working in epistemology, or concerned with issues involving the social dimensions of knowledge, should find the papers in this book both interesting and valuable.

This book explores the epistemic side of racial and sexual oppression. It elucidates how social insensitivities and imposed silences prevent members of different groups from listening to each other.

Group polarization—the tendency of groups to incline toward more extreme positions than initially held by their individual members—has been rigorously studied by social psychologists, though in a way that has overlooked important philosophical questions. This is the first book-length treatment of group polarization from a philosophical perspective. The phenomenon of group polarization raises several important metaphysical and epistemological questions. From a metaphysical point of view, can group polarization, understood as an epistemic feature of a group, be reduced to epistemic features of its individual members? Relatedly, from an epistemological point of view, is group polarization best understood as a kind of cognitive bias or rather in terms of intellectual vice? This book compares four models that combine potential answers to the metaphysical and epistemological questions. The models considered are: group polarization as (i) a collective bias; (ii) a summation of individual epistemic vices; (iii) a summation of individual biases; and (iv) a collective epistemic vice. Ultimately, the authors defend a collective vice model of group polarization over the competing alternatives. The Philosophy of Group Polarization will be of interest to students and researchers working in epistemology, particularly those working on social epistemology, collective epistemology, social ontology, virtue epistemology, and distributed cognition. It will also be of interest to those working on issues in political epistemology, applied epistemology, and on topics at the intersection of epistemology and ethics.

„We hold these truths to be self-evident, that all men are created equal...” This collection of essays addresses a philosophical problem raised by the first clause of these famous words. Does each signatory of the Declaration of Independence hold these truths individually, do they share some kind of a common attitude, or is there a single subject over and above the heads of its individual members that possesses a belief? “Collective Epistemology” is a name for the view that cognitive attitudes can be attributed to groups in a non-summative sense. The aim of this volume is to examine this claim, and to place it in the wider context of recent epistemological debates about the role of sociality in knowledge acquisition, in virtue and social epistemology, and in philosophy and sociology of science.

This book investigates how collaborative scientific practice yields scientific knowledge. At a time when most of today’s scientific knowledge is created in research groups, the author reconsiders the social character of science to address the question of whether collaboratively created knowledge should be considered as collective achievement, and if so, in which sense. Combining philosophical analysis with qualitative empirical inquiry, this book provides a comparative case study of mono- and interdisciplinary research groups, offering insight into the day-to-day practice of scientists. The book includes field observations and interviews with scientists to present an empirically-grounded perspective on much-debated questions concerning research groups’ division of labor, relations of epistemic dependence and trust.

This book brings together philosophers to investigate the nature and normativity of group disagreement across a range of political, religious, social, and scientific issues.
