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 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.

Mainstream analytic epistemology regards knowledge as the property of individuals, rather ‎than groups. Drawing on insights from the reality of knowledge production and dissemination ‎in the sciences, I argue, from within the analytic framework, that this view is wrong. I defend ‎the thesis of ‘knowledge-level justification communalism’, which states that at least some ‎knowledge, typically knowledge obtained from expert testimony, is the property of a ‎community and possibly none of its individual members, in that only the community or some ‎members (...) of it collectively possesses knowledge-level justification for its individual members’ ‎beliefs. I address several objections that individuals, qua individuals, have or are able to ‎acquire knowledge-level justification for all the beliefs they obtain from expert testimony. I ‎argue that the problem I identify with individualism is invariant under any specific account of ‎justification, internalist or externalist. ‎. (shrink)

In this paper, I argue that the following claims are jointly inconsistent: (1) that an agent’s justification for belief, if it’s constituted by evidence, depends on the profile of her background beliefs, (2) that whether or not a group believes a proposition is solely dependent on whether the proposition is jointly accepted by its members, and (3) that prototypical group beliefs are justified. I also raise objections to attempts to resolve the tension by retaining (2) and (3). The upshot is (...) a novel objection to the Joint Acceptance Account of group belief since it seems to be accompanied by a kind of skepticism. (shrink)

While social epistemology is a diverse field, much of it still understands knowledge as an individual status—albeit an individual status that crucially depends on various social factors (such as testimony). Further, the literature on group knowledge until now has primarily focused on limited, specialized groups that may be said to know this or that as a group. I wish to argue, to the contrary, that all knowledge-attributions ascribe a collective status; and that this follows more or less directly from an (...) essential function of entitlement-ascriptions: Ascriptions of knowledge and entitlement serve a primarily social function in that they facilitate coordination by maintaining consensus around true beliefs, true theories, and truth-producing methodologies. This conclusion will shed light on ways in which traditional theories of knowledge (such as foundationalism and coherentism) fail to capture a central function of our epistemic practice. (shrink)

We present a novel kind of “socio-functional” foundationalism rooted in the division of scientific labor. Our foundationalism is social in that it involves a socio-epistemic phenomenon we dub epistemic outsourcing, whereby claims from one group of scientists provide epistemological foundations for another group of scientists. We argue that: (1) epistemic outsourcing results in a legitimate form of epistemic foundationalism, (2) this sort of foundationalism can be used to shed light on the epistemology of measurement; and (3) epistemic outsourcing is a (...) distinctively collective epistemic phenomenon.

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 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)

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.

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.

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)
