People are often responsible for what they do, but they also often possess an excuse. One of the most common excuses is ignorance. Not all ignorance constitutes an excuse, however, for some ignorance is culpable and culpable ignorance is no excuse. But what about group agents? In our everyday practices, we blame group agents constantly. But if groups can be blameworthy, they plausibly can also be excused. Surely one such excuse is ignorance. But, as with individual agents, some group ignorance (...) is also surely culpable. How should we understand the culpable ignorance of group agents? In this paper, I argue for two conditional claims that together constitute what I call the Group Justification Thesis, which is a group-agent adaptation of the Justification Thesis put forth by Biebel [(2018). ‘Epistemic Justification and the Ignorance Excuse.’ Philosophical Studies 175 (12): 3005–3028]: (i) A group agent is excused because of ignorance only if that ignorance is justified, and (ii) a group agent is culpable despite being ignorant only if that ignorance is not justified. One interesting upshot of this view is that a group agent can be culpably ignorant even though none of the members are culpable for their ignorance. (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)

Joint acceptance accounts of group belief hold that groups can form a belief in virtue of the group members jointly accepting a proposition. Recently, Jennifer Lackey (2020, 2021) proposed a challenge to these accounts. If group beliefs can be based on joint acceptance, then it seems difficult to account for all instances of a group telling a lie. Given that groups can and do lie, our accounts of group belief better not result in us misidentifying some group lies as normal (...) assertions. I argue that Lackey’s argument is not decisive. The cases she proposes as challenges for joint acceptance accounts can be dealt with in the joint acceptance framework. I present two different readings of Lackey’s central case, showing that in both readings Lackey’s example of a problematic group lie should not be identified as a lie, but rather as an epistemic mistake by the group. What kind of mistake the group makes depends on the exact reading of Lackey’s case, but either way the group is not telling a lie. (shrink)

A long-standing debate in group ontology and group epistemology concerns whether some groups possess mental states and/or epistemic states such as knowledge that do not reduce to the mental states and/or epistemic states of the individuals who comprise such groups (and are also states not possessed by any of the members). Call those who think there are such states inflationists. There has recently been a defense in the literature of a specific type of inflationary knowledge—viz., knowledge of facts about group (...) minds or group self-knowledge (GS-K). In this paper I address whether some groups do possess such knowledge. I argue that we have good reason to think they do not. I do so by exploring the most explicit defense of such knowledge in the literature—Lukas Schwengerer’s (2022) defense—as well as other ways of defending this thesis and arguing that such ways are problematic. In the latter part of the paper, I explain why the two most popular inflationary approaches to group knowledge simpliciter are incompatible with there being GS-K. In doing so I work to show why even inflationists should reject the view that there is inflationary group self-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 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)

Jennifer Lackey (2016) challenged group acceptance accounts of justification by arguing that these accounts make the possession of evidence arbitrary and hence lead to illegitimate manipulation of the group's evidence. She proposes that the only way out is to rely on the epistemic propriety of the individual group members, which leads to a dilemma for group acceptance views: either they are wrong about justification, or they cease to rely only on group acceptances. I argue that there is a third option (...) based on general expectations of epistemic propriety that restricts the group's maximal justification. A group cannot be more justified than any individual in the group's position could be expected to be. I motivate this solution by a discussion of normative defeat and epistemic expectations as proposed by Goldberg (2018). (shrink)

Groups and other sorts of collective entities are frequently said to believe things. Sarah Huckabee Sanders, for instance, was asked by reporters at White House press conferences whether the Trump administration ‘believes in climate change’ or ‘believes that slavery is wrong’. Similarly, it is said on the website of the Aclu of Illinois that the organization ‘firmly believes that rights should not be limited based on a person’s sexual orientation or gender identity’. A widespread philosophical view is that belief on (...) the part of a group’s members is neither necessary nor sufficient for group belief. In other words, groups are said to be able to believe that p even when not a single individual member of the group believes that p. In this paper, I challenge this view by focusing on two phenomena that have been entirely ignored in the literature: group lies and group bullshit. I show that when group belief is understood in terms of actions over which group members have voluntarily control, as is standardly thought, paradigmatic instances of a group lying or bullshitting end up counting as a group believing. Thus we need to look elsewhere for an adequate account of group belief. (shrink)

While social epistemologists have recently begun addressing questions about whether groups can possess beliefs or knowledge, little has yet been said about whether groups can properly be said to possess understanding. Here I want to make some progress on this question by considering two possible accounts of group understanding, modeled on accounts of group belief and knowledge: a deflationary account, according to which a group understands just in case most or all of its members understand, and an inflationary account, according (...) to which a group’s understanding does not depend solely on whether its members understand. I argue that both accounts face problems. The deflationary account has two such problems: aggregation problems that are familiar from discussions of group belief, and the problem of different bases, wherein members possess understanding for different but consistent reasons. The inflationary account faces what I call the problem of distributed grasping: while it is widely accepted that understanding requires a kind of “grasping”, it is hard to make sense of how this requirement could be met at the group level while not necessarily being met by any individual member. Despite its problems, I make a case for the inflationary account. This will require addressing the problem of distributed grasping: to do this, I propose a different way of thinking about the grasping relation at the group level, such that it is constituted by a dependency relationship between members.

In the past two decades, epistemologists have significantly expanded the focus of their field. To the traditional question that has dominated the debate — under what conditions does belief amount to knowledge? — they have added questions about testimony, epistemic virtues and vices, epistemic trust, and more. This broadening of the range of epistemic concern has coincided with an expansion in conceptions of epistemic agency beyond the individualism characteristic of most earlier epistemology. We believe that these developments have not gone (...) far enough. While the weak anti-individualism we see in contemporary epistemology may be adequate for the kinds of cases it tends to focus on, a great deal of human knowledge production and transmission does not conform to these models. Furthermore, the dispositions and norms that are knowledge-conducive in the familiar cases may not be knowledge-conducive generally. In fact, dispositions that, at an individual level, count as epistemic vices may be epistemic virtues in common social contexts. We argue that this overlooked feature of human social life means that epistemology must become more deeply and pervasively social. (shrink)

Neste artigo iremos sistematizar os conceitos-chave da chamada epistemologia coletiva, apontando as diferentes teorias que explicam nossa prática de atribuição de estados cognitivos a grupos. Na introdução levantaremos o problema central que motiva a área, a saber: a atribuição de estados cognitivos a grupos tem como referente o grupo enquanto grupo ou os indivíduos que o compõe? Na primeira seção apresentaremos os melhores argumentos em favor do individualismo, aqueles que defendem que as atribuições se reduzem aos indivíduos. Na segunda, terceira (...) e quarta seções apresentaremos modelos coletivistas, que defendem uma certa autonomia do grupo frente aos indivíduos, o conjunto de membros que o compõe. Na quinta e sexta seções apresentaremos como modelos coletivistas explicam a atribuição de justificação e conhecimento a grupos. Nós concluímos notando que os ataques coletivistas ao individualismo são bastante efetivos, fazendo com que essa abordagem seja difícil de sustentar, e apontando outros elementos que são necessários para a construção de um modelo coletivista completo.

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)

One can know how to ride a bicycle, play the cello, or collect experimental data. But who can know how to properly ride a tandem bicycle, perform a symphony, or run a high-energy physics experiment? Reductionist analyses fail to account for these cases strictly in terms of the individual know-how involved. Nevertheless, it doesn't follow from non-reductionism that groups possess this know-how. One must first show that epistemic extension cannot obtain. This is the idea that individuals can possess knowledge even (...) when others possess some of the epistemic materials generating it. I show that only knowledge-that can be epistemically extended, not knowledge-how. Appeal to epistemic extension is a viable way of avoiding group knowledge-that ascriptions but not group knowledge-how ascriptions. Therefore, groups can know how. (shrink)

This essay raises new objections to the two dominant approaches to understanding the justification of group beliefs—_inflationary_ views, where groups are treated as entities that can float freely from the epistemic status of their members’ beliefs, and _deflationary_ views, where justified group belief is understood as nothing more than the aggregation of the justified beliefs of the group's members. If this essay is right, we need to look in an altogether different place for an adequate account of justified group belief. (...) From these objections emerges the skeleton of the positive view that this essay goes on to develop and defend, called the _group epistemic agent account_: groups are epistemic agents in their own right, with justified beliefs that respond to both evidence and normative requirements that arise only at the group level but that are nonetheless importantly constrained by the epistemic status of the beliefs of their individual members.

In this paper, I provide the framework for an account of group assertion. On my view, there are two kinds of group assertion, coordinated and authority-based, with authority-based group assertion being the core notion. I argue against a deflationary view, according to which a group’s asserting is understood in terms of individual assertions, by showing that a group can assert a proposition even when no individual does. Instead, I argue on behalf of an inflationary view, according to which it is (...) the group itself that asserts, a conclusion supported by the fact that paradigmatic features of assertion apply only at the level of the group. A central virtue of my account is that it appreciates the important relationship that exists between most groups and their spokespersons, as well as the consequences that follow from this relationship. My view, thus, provides the framework for distinguishing when responsibility for an assertion lies at the collective level, and when it should be shouldered by an individual simply speaking for herself.

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)

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.
