Epistemic diversity is the ability or possibility of producing diverse and rich epistemic apparati to make sense of the world around us. In this paper we discuss whether, and to what extent, different conceptions of knowledge—notably as ‘justified true belief’ and as ‘distributed and embodied cognition’—hinder or foster epistemic diversity. We then link this discussion to the widespread move in science and philosophy towards monolingual disciplinary environments. We argue that English, despite all appearance, is no (...) Lingua Franca, and we give reasons why epistemic diversity is also deeply hindered is monolingual contexts. Finally, we sketch a proposal for multilingual academia where epistemic diversity is thereby fostered. (shrink)

Philosophers of science have argued that epistemic diversity is an asset for the production of scientific knowledge, guarding against the effects of biases, among other advantages. The growing privatization of scientific research, on the contrary, has raised important concerns for philosophers of science, especially with respect to the growing sources of biases in research that it seems to promote. Recently, Holman and Bruner ( 2017 ) have shown, using a modified version of Zollman ( 2010 ) social network (...) model, that an industrial selection bias can emerge in a scientific community, without corrupting any individual scientist, if the community is epistemically diverse. In this paper, we examine the strength of industrial selection using a reinforcement learning model, which simulates the process of industrial decision-making when allocating funding to scientific projects. Contrary to Holman and Bruner’s model, in which the probability of success of the agents when performing an action is given a priori, in our model the industry learns about the success rate of individual scientists and updates the probability of success on each round. The results of our simulations show that even without previous knowledge of the probability of success of an individual scientist, the industry is still able to disrupt scientific consensus. In fact, the more epistemically diverse the scientific community, the easier it is for the industry to move scientific consensus to the opposite conclusion. Interestingly, our model also shows that having a random funding agent seems to effectively counteract industrial selection bias. Accordingly, we consider the random allocation of funding for research projects as a strategy to counteract industrial selection bias, avoiding commercial exploitation of epistemically diverse communities.

This paper offers a new angle on the common idea that the process of science does not support epistemic diversity. Under minimal assumptions on the nature of journal editing, we prove that editorial procedures, even when impartial in themselves, disadvantage less prominent research programs. This purely statistical bias in article selection further skews existing differences in the success rate and hence attractiveness of research programs, and exacerbates the reputation difference between the programs. After a discussion of the modeling (...) assumptions, the paper ends with a number of recommendations that may help promote scientific diversity through editorial decision making. (shrink)

Feminist epistemology aims to propose epistemic reasons for increasing the representation of women or socially subordinated people in science. This is typically done—albeit often only implicitly—by positing a causal mechanism through which the representation of sociodemographic minorities exerts a positive effect on scientific advancement. Two types of causal theories can be identified. The “epistemic diversity thesis” presents a causal path from sociodemographic diversity to scientific progress mediated by epistemic diversity. The “thesis of epistemic (...) advantage” proposes a causal path from social subjugation to capacity for inquiry. The latter theory is defined with substantial ambiguity in the existing literature, and I present an explicit causal reformulation that disambiguates it. The epistemic diversity thesis focuses on the effect of group composition on collective epistemic performance and is largely silent about what kind of characteristics lead to individual epistemic excellence. On the other hand, the thesis of epistemic advantage seeks to identify sociodemographic background conditions that make certain epistemic agents strictly better knowers or inquirers than others and pays little attention to the synergistic effects of diverse group composition. Such a difference in the causal structure reflects the diverging political characteristics of the two theories. (shrink)

Epistemic diversity is widely approved of by social epistemologists. This paper asks, more specifi cally, how much epistemic diversity, and what kinds of epistemic diversity are normatively appropriate? Both laissez-faire and highly directive approaches to epistemic diversity are rejected in favor of the claim that diversity is a blunt epistemic tool. There are typically a number of diff erent options for adequate diversifi cation. The paper focuses on scientifi c domains, (...) with particular attention to recent theories of smell. (shrink)

Classical Athens provides a historical case study of effective joint action by a democratic community, at scale, over time, and across a socially and epistemically diverse population. Athens was concerned both with aggregating diverse knowledge for decision-making and with building common knowledge for coordinated joint action. A preserved prosecution speech delivered in an Athenian treason trial reveals how common knowledge was generated by democratic institutions and employed in legal arguments. Common knowledge facilitated eff ective coordination among citizens through productive alignment (...) cascades. Yet Athenian lawcourt procedures rendered cascading difficult, pointing to an institutionalized awareness that coordination among jurors might violate fairness as equality before the law; such violations threatened democratic values and the equilibrium between elite and non-elite citizens. Common knowledge was promoted by repeated public rituals, public monuments, and public architecture that allowed for the interpresence of large numbers of deliberative and intervisible citizens.

I argue that Open Science as currently conceptualized and implemented does not take sufficient account of epistemic diversity within research. I use three case studies to exemplify how Open Science threatens to privilege some forms of inquiry over others, thus exasperating divides within and across systems of practice, and overlooking important sources and forms of epistemic diversity. Building on insights from pluralist philosophy, I then identify four aspects of diverse research practices that should serve as reference (...) points for debates around Open Science: (1) specificity to local conditions, (2) entrenchment within repertoires, (3) permeability to newcomers, and (4) demarcation strategies.

The current regulatory regime for pharmaceuticals is criticized from a libertarian perspective for imposing the same risk–benefit analysis on all patients. The critics call for the abandonment of market access regulations. But the regulatory regime is also criticized by philosophers of science for applying too low epistemic standards, who call for stricter regulation. This article aims to engage the debate in a less polarized way, first by advancing the libertarian alternative to the current regime through an approach I call (...) Certified Capitalism for Pharmaceuticals (CCP), without endorsing this view in the end; second, by developing an argument against all regulatory regimes without market access regulations, including CCP, based on the possibility that the pharmaceutical industry could bend pharmaceutical science to its interests in such a regime. Whether this argument is successful, or whether CCP is able to circumvent it, cannot be decided on the basis of the empirical information currently available. Third, these arguments lead to two further insights for a philosophy of science that takes the social embeddedness of science seriously: Market access regulations limit the bending of research by industry by limiting epistemic diversity. The patent system can be seen as the thread of a well-functioning scientific system because it can give some agents enough resources to bend science through industrial selection. (shrink)

Although John Stuart Mill places considerable emphasis on three information signalling devices – debate, votes and prices – he remains curiously sceptical about the prospects of institutional or social epistemology. In this paper, I explore Mill's modest scepticism about institutional epistemolog y and compare and contrast that with the attitudes of liberal theorists such as F. A. Hayek and John Dewey who are much more enthusiastic about the prospects of social epistemology as part of their defences of liberalism. The paper (...) examines the extent to which Hayek and Dewey ignore concerns originally raised by Mill. I conclude that Mill's modest scepticism is reflected in the epistemological abstinence of contemporary liberal philosophers such as John Rawls, and that his elevation of philosophy over democracy remains a challenge to contemporary defenders of the political value of social or institutional epistemology.

In “Epistemology Naturalized” Quine famously suggests that epistemology, properly understood, “simply falls into place as a chapter of psychology and hence of natural science” (1969, 82). Since the appearance of Quine’s seminal article, virtually every epistemologist, including the later Quine (1986, 664), has repudiated the idea that a normative discipline like epistemology could be reduced to a purely descriptive discipline like psychology. Working epistemologists no longer take Quine’s vision in “Epistemology Naturalized” seriously. In this paper, I will explain why I (...) think this is a mistake. (shrink)

A concept of diversity is an understanding of what makes a group diverse that may be applicable in a variety of contexts. We distinguish three diversity concepts, show that each can be found in discussions of diversity in science, and explain how they tend to be associated with distinct epistemic and ethical rationales. Yet philosophical literature on diversity among scientists has given little attention to distinct concepts of diversity. This is significant because the unappreciated (...) existence of multiple diversity concepts can generate unclarity about the meaning of “diversity,” lead to problematic inferences from empirical research, and obscure complex ethical-epistemic questions about how to define diversity in specific cases. We illustrate some ethical-epistemic implications of our proposal by reference to an example of deliberative mini-publics on human tissue biobanking. (shrink)

First, the article illustrates the concept of ‘cultural heritage’ as traditionally meant, namely relying on a historically consolidated narrative. Next, it undertakes a broader conceptual analysis and deals with three distinct issues: (i) the fact that the conceptualizations and uses of heritage largely depend on long lasting dichotomies (e.g., tangible/intangible, natural/cultural); (ii) the way in which cultural backgrounds shape the dynamics of valuing and approaching heritage; (iii) the temporal framing of heritage, which today, in the Anthropocene, also points towards how (...) to deal with a future of uncertainty. Lastly, it introduces the notion of epistemic heritage, (i.e., the existence of multiple cultural ways of knowing), investigating its implications for both how cultural heritage is conceived and the future approached.

Pessimism over a democracy’s ability to produce good outcomes is as longstanding as democracy itself. On one hand, democratic theorists consider democracy to be the only legitimate form of government on the basis that it alone promotes or safeguards intrinsic values like freedom, equality, and justice. On the other, skepticism toward the ordinary citizen’s cognitive capacities remains a perennial concern. Qualms about the epistemic value of democracy have only been made more pertinent by a fundamental problem of deep (...) class='Hi'>epistemic disagreement which underlies the post-truth phenomenon. I argue that the democratic theorists who have sought to defend democracy on epistemic grounds have thus far neglected such deep and intractable disagreements. Without addressing this oversight, the epistemic democrat will find that collective decision-making processes quickly become paralyzed and will not be able to yield the epistemic benefits they promise. Hence, the work for epistemic democrats is to recognize and take into account the ramifications of epistemic disagreements so as to make a stronger case for epistemic democracy. (shrink)

We carry out most of our epistemic projects as groups. Networks of individuals work together to identify questions, accumulate evidence, and settle on answers that lie beyond the ken of individual knowers. This is particularly important for controversial issues. And when it comes to ideologically contested issues, groups that are ideologically diverse in their membership are epistemically superior to groups that are ideologically homogenous. That’s because ideologically diverse groups are better at (a) identifying a representative sample of important questions, (...) (b) developing a wider range of potential answers, and (c) evaluating the evidence for and against each option. Awareness of this point produces a competence defeater for the relevant outputs of ideologically homogenous groups: they don’t deserve the high level of trust we often grant them. That, among other things, goes a long way towards justifying the public’s decreased trust in institutions like social networks, journalism, and universities. (shrink)

Throughout scientific history, there have been cases of mainstream science dismissing novel ideas of less prominent researchers. Nowadays, many researchers with different social and academic backgrounds, origins and gender identities work together on topics of crucial importance. Still, it is questionable whether the privileged groups consider the views of underprivileged colleagues with sufficient attention. To profit from the diversity of thoughts, the scientific community first has to be open to minority viewpoints and epistemically include them in mainstream research. Moreover, (...) the idea of inclusive science poses stronger requirements than the paradigm of open science. We argue that the concept of integration of different opinions is insufficient because the process of integration assumes adjusting oneself to the majority view and fitting into the dominant paradigm while contributing only with smaller amendments. Epistemic inclusion, on the other hand, means dynamically changing the research paradigm during the interaction with diverse methods and hypotheses. The process of inclusion preserves marginalized views and increases epistemic justice. (shrink)

The Hong and Page ‘diversity trumps ability’ result has been used to argue for the more general claim that a diverse set of agents is epistemically superior to a comparable group of experts. Here we extend Hong and Page’s model to landscapes of different degrees of randomness and demonstrate the sensitivity of the ‘diversity trumps ability’ result. This analysis offers a more nuanced picture of how diversity, ability, and expertise may relate. Although models of this sort can (...) indeed be suggestive for diversity policies, we advise against interpreting such results overly broadly. (shrink)

There is growing interest in understanding and eliciting division of labor within groups of scientists. This paper illustrates the need for this division of labor through a historical example, and a formal model is presented to better analyze situations of this type. Analysis of this model reveals that a division of labor can be maintained in two different ways: by limiting information or by endowing the scientists with extreme beliefs. If both features are present however, cognitive diversity is maintained (...) indefinitely, and as a result agents fail to converge to the truth. Beyond the mechanisms for creating diversity suggested here, this shows that the real epistemic goal is not diversity but transient diversity. (shrink)

In Democratic Reason, Hne Landemore has built a case for the epistemic virtues of inclusive deliberative democracy based on the cognitive diversity of the group engaged in making collective decisions. She supports her thesis by appealing to the Diversity Trumps Ability Theorem of Lu Hong and Scott Page. This theorem is quite technical and the informal statements of it aimed at democratic theorists are inaccurate, which has resulted in some misguided critiques of the theorem's applicability to democratic (...) politics. This paper provides an exposition of the Diversity Trumps Ability Theorem that does not sacrifice precision for accessibility. It also shows that it is not possible to satisfy the assumptions of this theorem when there are only two options. Thus, the Diversity Trumps Ability Theorem cannot provide support for the epistemic virtues of inclusive democratic deliberation for binary collective decisions. (shrink)

In the literature on inclusion and inclusive education there is a frequent conflation of inclusion of diverse people, or people in all their diversity, inclusion of diverse worldviews, and inclusion of diverse epistemologies. Only the first of these is plausible—and perhaps even morally and politically mandatory. Of course, more needs to be said about inclusion and its possible difference from integration, conditions of access, etc. Regarding the second type of inclusion, not all worldviews merit inclusion. Moreover, worldviews and epistemologies (...) are not identical: everyone may have a worldview but not everyone has an epistemology. Finally, the idea of diverse epistemologies makes only limited sense, as do the associated notions of ‘indigenous knowledge’, ‘legitimation of knowledge’ and ‘epistemic marginalisation’. (shrink)

Demographic diversity might often be present in a group without group members noticing it. What are the epistemic effects if they do? Several philosophers and social scientists have recently argued that when individuals detect demographic diversity in their group, this can result in epistemic benefits even if that diversity doesn’t involve cognitive differences. Here I critically discuss research advocating this proposal, introduce a distinction between two types of detection of demographic diversity, and apply this (...) distinction to the theorizing on diversity in science. Focusing on ‘invisible’ diversity, I argue that in one common kind of group in science, if group members have full insight into their group’s diversity, this is likely to create epistemic costs. These costs can be avoided and epistemic benefits gained if group members only partly detect their group’s diversity. There is thus an epistemic reason for context-dependent limitations on scientists’ insight into the diversity of their group. (shrink)

A familiar criticism of religious belief starts from the claim that a typical religious believer holds the particular religious beliefs she does just because she happened to be raised in a certain cultural setting rather than some other. This claim is commonly thought to have damaging epistemological consequences for religious beliefs, and one can find statements of an argument in this vicinity in the writings of John Stuart Mill and more recently Philip Kitcher, although the argument is seldom spelled out (...) very precisely. This paper begins by offering a reconstruction of an argument against religious beliefs from cultural contingency, which proceeds by way of an initial argument to the unreliability of the processes by which religious beliefs are formed, whose conclusion is then used to derive two further conclusions, one which targets knowledge and the other, rationality. Drawing upon recent work in analytic epistemology, I explore a number of possible ways of spelling out the closely related notions of accidental truth, epistemic luck, and reliability upon which the argument turns. I try to show that the renderings of the argument that succeed in securing the sceptical conclusion against religious beliefs also threaten scepticism about various sorts of beliefs besides religious beliefs.

This article briefly considers current positions about whether the inclusion of the perspectives and interests of marginalised groups in the construction of knowledge is of epistemic value. It is then argued that applied social epistemology is the proper epistemic stance to take in evaluating this question. Theorists who have held that diversity makes an epistemic contribution are interpreted as attempting to reform social pathways to knowledge in ways that make true belief more likely. Thus, the demand (...) for diversity challenges the individualistic and a priori nature of traditional epistemology. This stance has consequences for education. It supports greater attention to helping students examine the testimonial bases for their beliefs. And it prepares students for their role as citizens in supporting policies that maintain credible inclusive institutions of public knowledge. (shrink)

Functional diversity holds the promise of understanding ecosystems in ways unattainable by taxonomic diversity studies. Underlying this promise is the intuition that investigating the diversity of what organisms actually do—i.e. their functional traits—within ecosystems will generate more reliable insights into the ways these ecosystems behave, compared to considering only species diversity. But this promise also rests on several conceptual and methodological—i.e. epistemic—assumptions that cut across various theories and domains of ecology. These assumptions should be clearly (...) addressed, notably for the sake of an effective comparison and integration across domains, and for assessing whether or not to use functional diversity approaches for developing ecological management strategies. The objective of this contribution is to identify and critically analyze the most salient of these assumptions. To this aim, we provide an “epistemic roadmap” that pinpoints these assumptions along a set of historical, conceptual, empirical, theoretical, and normative dimensions. (shrink)

A lack of diversity remains a significant problem in many STEM communities. According to the epistemic approach to addressing these diversity problems, it is in a community’s interest to improve diversity because doing so can enhance the rigor and creativity of its work. However, we draw on empirical and theoretical evidence illustrating that this approach can trade on the epistemic exploitation of diverse community members. Our concept of epistemic exploitation holds when there is a (...) relationship between two parties in which one party accrues epistemic benefits from another party’s knowledge and epistemic location and, in doing so, harms the second party or sets back their interests. We demonstrate that the ironic outcome of this nominal application of the epistemic approach is that it undermines the epistemic benefits which it promises. Indeed, we show that epistemic exploitation undermines the relationships and interactions among community members that produce rigor and creativity. Our central argument is that for communities to reap the benefits of an epistemic approach to diversity, to implement a genuine epistemic approach, they need to develop cultures that ameliorate the harms faced by, and protect the interests of, their diverse community members.

In Clough’s reply paper to me (http://wp.me/p1Bfg0-1aN), she laments how feminist calls for diversity within scientific communities are inadvertently sidelined by our shared feminist empiricist prescriptions. She offers a novel justification for diversity within epistemic communities and challenges me to accept this addendum to my prior prescriptions for biomedical research communities (Goldenberg 2013) on the grounds that they are consistent with the epistemic commitments that I already endorse. In this response, I evaluate and accept her challenge.

We may well be witnessing a decisive event in the history of knowledge as diversity is becoming one of the premier values of late modern societies. We seek to preserve and foster biodiversity, neurodiversity, racial diversity, ethnic diversity, gender diversity, linguistic diversity, cultural diversity, and perspectival diversity. Perspectival diversity has become the passage point through which other forms of diversity must pass to become epistemically consequential. This article examines how two of (...) its varieties, viewpoint diversity and educational diversity, have come to transform the moral economy of science. Both aim at multiplying perspectives on a given subject, but their political subtexts differ markedly. The valorization of educational diversity followed a US Supreme Court decision in 1978 that enabled universities to advance social justice, if they justified race-conscious admissions in terms of the pedagogic benefits of a more diverse student body for all. By contrast, the proponents of viewpoint diversity aim at the reform of scientific knowledge production and distribution rather than the reallocation of status and power among different social groups. We examine the political epistemology of viewpoint diversity by analyzing a controversy between social psychologists who, amid the American culture wars of the 2010s, debated how to rein in their political biases in a scientific field supposedly lacking political diversity. Out of this scientific controversy grew Heterodox Academy, an activist organization promoting viewpoint diversity in higher education. By relating and comparing viewpoint and educational diversity, we clarify what is at stake epistemically in the US-centric moral economy of diversity. (shrink)

Historical Epistemology: On the Diversity and Change of Epistemic Values in Science. Historical epistemology involves the claim that the system of scientific knowledge is not determined by the observations but is also subject to epistemic requirements that may change in the historical process of doing research. As a result, the system of knowledge is path‐dependent in that its shape is contingent on epistemic choices made at certain historical points. I attempt to elaborate this approach by drawing (...) attention to the double role of epistemic values. First, such values create relations of significance and thereby contribute to directing research into certain avenues. Second, they are also important in the process of confirmation in that they entail that certain forms of agreement with the facts are superior and preferable to other such forms. Some epistemic orientations and reorientations can be reconstructed as arising from an interaction with nature, but others are based on commitments to the kind of knowledge we appreciate. The epistemic authority of science is created in large measure by rules of the scientific community that express how to deal with knowledge claims. (shrink)

Sceptics have been accused of achieving their sceptical conclusions by an arbitrary (though usually implicit) redefinition of terms like “justified”, so that, while it may be true that no belief is justified in the sceptic’s new sense of the word, all the beliefs we have taken as justified remain so in the ordinary, standard meaning of the term. This paper defends scepticism against this charge. It is pointed out that there are several sorts of case where someone’s belief may be (...) properly termed justified in one “sense”, or from one “point of view”, but from another, equally properly termed unjustified. It is argued that the point of view of the sceptic, or the sense in which he uses the term, is one of the perfectly standard ones, and not some arbitrarily introduced new sense. In addition, an explanation that is not damaging to scepticism is provided of a sceptic’s own continued ascriptions of justifiedness in everyday contexts. (shrink)

This paper contributes to growing debates over the decision-making ability of democracy by considering the epistemic value of deliberative democracy. It focuses on the benefits democratic deliberation can derive from its diversity, and the extent to which these benefits can be realised with respect to the complexities of political problems. The paper first calls attention to the issue of complexity through a critique of Hélène Landemore and the Diversity Trumps Ability Theorem. This approach underestimates complexity due to (...) its reliance on an ‘oracle assumption’ and this is shown to highlight more general difficulties for applying the benefits of diversity to the realities of political problems. The paper then develops a new model of deliberation—based on an relationship between cognitive diversity and diminishing returns to cognitive type—which does not involve an oracle assumption and can therefore support the epistemic value of deliberative democracy even for complex problems. The benefits of diversity are also argued to be better realised though sortition than either democratic elections or epistocracy, pointing to the value of deliberation between randomly selected citizens. Finally, and contrary to past work, the new account suggests that diversity cannot alone establish the superiority of democratic deliberation over all non-democratic alternatives, and that it is insufficient to mount a purely epistemic argument for deliberative democracy. The paper therefore furthers our understanding of the epistemic value of deliberative democracy by clarifying when and to what extent diversity is a benefit to political problem solving. (shrink)

There exists a diversity of "evidence-free" religions, contradicting one an- other. There will be an epistemic problem for a religious devotee either because evidence-free belief is in general not epistemically justified in the face of diversity, or because of a special problem in the religious case. I argue that in general evidence-free belief is epistemically justified in the face of diversity. Then I argue that recent arguments of Wykstra and Basinger fail to show that there is (...) a special problem in the religious case. Finally, I give reasons why religious belief is epistemically justified in the face of diversity. (shrink)

It is well known that AI-based language technology—large language models, machine translation systems, multilingual dictionaries, and corpora—is currently limited to three percent of the world’s most widely spoken, financially and politically backed languages. In response, recent efforts have sought to address the “digital language divide” by extending the reach of large language models to “underserved languages.” We show how some of these efforts tend to produce flawed solutions that adhere to a hard-wired representational preference for certain languages, which we call (...) language modeling bias. Language modeling bias is a specific and under-studied form of linguistic bias were language technology by design favors certain languages, dialects, or sociolects with respect to others. We show that language modeling bias can result in systems that, while being precise regarding languages and cultures of dominant powers, are limited in the expression of socio-culturally relevant notions of other communities. We further argue that at the root of this problem lies a systematic tendency of technology developer communities to apply a simplistic understanding of diversity which does not do justice to the more profound differences that languages, and ultimately the communities that speak them, embody. Drawing on the concept of epistemic injustice, we point to the broader ethico-political implications and show how it can lead not only to a disregard for valuable aspects of diversity but also to an under-representation of the needs of marginalized language communities. Finally, we present an alternative socio-technical approach that is designed to tackle some of the analyzed problems. (shrink)

Bruner shows that in cultural interactions, members of minority groups will learn to interact with members of majority groups more quickly—minorities tend to meet majorities more often as a brute fact of their respective numbers—and, as a result, may come to be disadvantaged in situations where they divide resources. In this paper, we discuss the implications of this effect for epistemic communities. We use evolutionary game theoretic methods to show that minority groups can end up disadvantaged in academic interactions (...) like bargaining and collaboration as a result of this effect. These outcomes are more likely, in our models, the smaller the minority group. They occur despite assumptions that majority and minority groups do not differ with respect to skill level, personality, preference, or competence of any sort. Furthermore, as we will argue, these disadvantaged outcomes for minority groups may negatively impact the progress of epistemic communities. (shrink)

There are widespread calls for increased demographic diversity in science, often linked to the epistemic claim that including more perspectives will improve the quality of the knowledge produced. By distinguishing between demographic and epistemic diversity, we show that this is only true some of the time. There are cases where increasing demographic diversity will not bring about the necessary epistemic diversity and cases where failing to exclude some voices reduces the quality of the (...) scientific debate. We seek to resolve these tensions with an analysis that turns on the way the experience-based expertise of non-scientists can be absorbed into mainstream science. Mostly it has to be done via what we call ‘virtual diversity’, in which scientists take responsibility for acquiring interactional expertise in the non-scientific expertise-based domains which they consider provide knowledge valuable to the science. We argue that virtual diversity represents the only feasible option in most scenarios, with cases where demographic diversity or full cultural mergers provide the solution being the exception rather than the rule. This analysis is an exercise in the sociology of knowledge, which is considered as being continuous with philosophy. The paper is prescriptive as well as descriptive, and the moral, cultural, political, and educational implications of the argument are drawn out. A main conclusion is that the acquisition of virtual diversity should be a new norm for science, allowing the voices of experienced non-scientist citizens to be heard but without eroding the institution of science, which continues to be a vital foundation of truth in democracy.

A teoria das virtudes epistêmicas (VE) sustenta que as virtudes dos agentes, tais como a imparcialidade ou a permeabilidade intelectual, ao invés de crenças específicas, devem estar no centro da avaliação epistêmica, e que os indivíduos que possuem essas virtudes estão mais bem-posicionados epistemicamente do que se não as tivessem, ou, pior ainda, do que se tivessem os vícios correspondentes: o preconceito, o dogmatismo, ou a impermeabilidade intelectual. Eu argumento que a teoria VE padece de um grave defeito, porque fracassa (...) ao se ajustar à natureza social dos questionamentos (epistêmicos) típicos. Esse e outros defeitos relacionados a esse infectam o paralelo que os teóricos VE traçam entre virtudes epistêmicas e morais. Ao prometer o incremento na proporção de crenças verdadeiras sobre crenças falsas, ou ignorância, as virtudes epistêmicas não podem desempenhar um papel paralelo àquele que Aristóteles reserva às virtudes morais ao prometer o incremento em nossa felicidade e no bem-estar da comunidade. A minha rota para essas críticas é feita das razões sobre por que os agentes (sociais) devem buscar a obtenção de seus objetivos morais e epistêmicos diferentemente nos papéis que atribuem às virtudes. PALAVRAS-CHAVES – Virtude epistêmica. Divisão de trabalho epistêmico. Diversidade. Conhecimento. Falibilidade. Virtude moral. ABSTRACT Epistemic Virtue (EV) theory holds that virtues of agents, like impartiality or openmindedness, rather than specific beliefs, should be at the center of epistemological evaluation, and that individuals with those virtues are better positioned epistemically than if they lacked them or, worse, if they instead had the corresponding vices: prejudice, dogmatism, or close-mindedness. I argue that EV theory suffers from a serious flaw because it fails to accommodate to the social nature of typical (epistemic) inquiries. This and related flaws infect the parallel that EV theorists allege between epistemic and moral virtues. In promising to improve our ratio of true beliefs to either false beliefs or ignorance, the epistemic virtues cannot play a roll parallel to that which Aristotle claims for the moral virtues in promising to increase our happiness and the well-being of the community. The path to these criticisms I introduce by offering reasons for why (social) agents should seek to realize their epistemic and moral goals very differently in the respective roles they accord to the virtues. KEY WORDS – Epistemic virtue. Division of epistemic labor. Diversity. Knowledge. Fallibility. Moral virtue. (shrink)

This paper argues in favor of the epistemic properties of inclusiveness in the context of democratic deliberative assemblies and derives the implications of this argument in terms of the epistemically superior mode of selection of representatives.

When applied to deliberative assemblies of representatives, where there is an upper limit to the number of people that can be included in the (...) group, the argument translates into a defense of a specific selection mode of participants: random selection.

We suggest that philosophical accounts of epistemic effects of diversity have given insufficient attention to the relationship between demographic diversity and information elaboration, the process whereby knowledge dispersed in a group is elicited and examined. We propose an analysis of IE that clarifies hypotheses proposed in the empirical literature and their relationship to philosophical accounts of diversity effects. Philosophical accounts have largely overlooked the possibility that demographic diversity may improve group performance by enhancing IE, and (...) sometimes fail to explore the relationship between diversity and IE altogether. We claim these omissions are significant from both a practical and theoretical perspective. Moreover, we explain how the overlooked explanations suggest that epistemic benefits of diversity can depend on epistemically unjust social dynamics. (shrink)

The topic of the thesis is the challenge that religious diversity poses to religious belief. A key issue to be resolved is whether a reasonable person may believe in the epistemic superiority of any one religious ideology in the light of religious diversity. -/- After introducing the issues, I examine Richard Swinburne’s, and then Alvin Plantinga’s, view on religious diversity. These two philosophers both advocate religious epistemic exclusivism, the view that only one religious ideology is (...) true to the exclusion of all others. I argue that the positions of Swinburne and Plantinga are unsatisfactory. -/- In Chapter ‎4 I list a number of objections to religious epistemic exclusivism. One of these objections, namely the religious ambiguity objection, will be important in this thesis. I explain what religious ambiguity is in more detail and distinguish between temporary religious ambiguity and permanent religious ambiguity. -/- Chapters ‎5 & 6 deal with responses to religious diversity in the light of permanent religious ambiguity. William Alston advocates that religious epistemic exclusivism is still reasonable given religious ambiguity. Alston appeals to faith to justify exclusivist belief but this gives rise to the objection that tentative belief is more appropriate. Conversely, John Hick rejects exclusivism in favour of another position altogether, called religious epistemic pluralism. In Chapter ‎7 I assess the impact of Hick’s response to religious diversity on the ideology of a traditionally minded Muslim. I argue that the Muslim is not obliged to accept Hick’s solution in full.

The present argument assumes that teaching through modeling attempts to teach the intellectual virtues not primarily as an independent goal of education as, for example, a way to build good character, but for its value to inquiry. I argue that intellectual vices (such as being gullible, dogmatic, pigheaded, or prejudiced)—while harmful to inquiry in certain ways—are essential to its well functioning. Furthermore, to the extent that teaching models critical inquiry, there are educational lessons for which some students ought to take (...) a dogmatic or narrow minded commitment to certain hypotheses or positions; and then, insofar as this modeling works, it will promote these intellectual vices. In Part I of what follows, I develop my argument; in Part II, I respond to the objection that diversity of ideas and attitudes need not—and ought not—call upon the promotion of intellectual vices.

It is often assumed that democracies can make good use of the epistemic benefi ts of diversity among their citizenry, but difficult to show why this is the case. In a deliberative democracy, epistemically relevant diversity has three aspects: the diversity of opinions, values, and perspectives. Deliberative democrats generally argue for an epistemic form of Rawls' difference principle: that good deliberative practice ought to maximize deliberative inputs, whatever they are, so as to benefi t all (...) deliberators, including the least eff ective. The proper maximandum of such a principle is not the pool of reasons, but rather the availability of perspectives. Th is sort of diversity makes robustness across different perspectives the proper epistemic aim of deliberative processes. Robustness also offers a measure of success for those democratic practices of inquiry based on the deliberation of all citizens. (shrink)

This article examines the business case for diversity, according to which diversity should be promoted because diverse groups outperform nondiverse groups. Philosophers who defend BCD usually...

Narratives of seed ‘loss’ and ‘persistence’ remain at loggerheads. Crop genetic diversity is rapidly eroding worldwide, we are told, and numerous studies support this claim. Other data, however, suggests an alternative storyline: far from disappearing, seed diversity persists around the world, resisting the homogenizing forces of modern capitalism. Which of these accounts is closer to the truth? As it turns out, crop biodiversity is more easily invoked than measured, more easily wielded than understood. In this essay, I contend (...) that the impasse reveals an error in the asking. We must, instead, look to the ontological, epistemic, and narrative dimensions of agrobiodiversity—and to the science, politics, and cultures of each. How is diversity empirically defined and measured? Who creates and categorizes diversity? Who does not? How is such knowledge mobilized in the accounts and narratives of different interest groups? Where, when, and why does a narrative hold true? This multi-dimensional view of agrobiodiversity makes space for a greater understanding of how diversity is created, maintained, and renewed. It suggests policy and institutional support for systems that engender such renewal of diversity, both in and ex situ. (shrink)

John Hick's God or Reality centered religious philosophy was claimed by him to be a Copernican revolution in epistemology of God. Is it really so? This article investigates.

This article contributes to the revision of the procedure of robustness analysis of mathematical models in epistemic democracy using the systematic review method. It identifies the drawbacks of robustness analysis in epistemic democracy in terms of sample universality and inference from samples with the same results. To exemplify the effectiveness of systematic review, this article conducted a pilot review of diversity trumps ability theorem models, which are mathematical models of deliberation often cited by epistemic democrats. A (...) review of nine models extracted from 352 papers exemplifies the effectiveness of robustness analysis supplemented by systematic review in epistemic democracy. (shrink)

This paper characterizes a phenomenon I call ‘binarism grammatical lacuna’ (BGL). BGL occurs when non-binary sex and gender identities are forced to choose between being he or she by the grammar of a language owing to the sex/gender binary. Although hermeneutical injustice (HI) lies at its core, given that non-binary communities come up with hermeneutical devices to overcome unintelligibility and these tools are discredited, a variety of epistemic injustices, besides HI, intertwine in BGL. I address contributory injustice, pragmatic competence (...) injustice, testimonial injustice, and testimonial smothering. Section 1 introduces the phenomenon by portraying it as an ensemble of epistemic injustices. Section 2 elucidates the variety of HI at the core of BGL by examining the case of mainstream Spanish, and section 3 reveals it as producing the primary harm of HI. Section 4 studies the relationship between grammar, ideology, and language use, calling attention to the fact that grammatical lacunae are performatively reenacted in daily speech acts. Section 5 explores the agential dimension of BGL, examining responsibilities. In addition to addressing some of the forms of epistemic injustice that might intertwine in BGL besides HI, I portray non-marginalized users of binary grammar when addressing non-binary people as hermeneutical misfirers.

In a series of formal studies and less formal applications, Hong and Page offer a ‘diversity trumps ability’ result on the basis of a computational experiment accompanied by a mathematical theorem as explanatory background (Hong & Page 2004, 2009; Page 2007, 2011). “[W]e find that a random collection of agents drawn from a large set of limited-ability agents typically outperforms a collection of the very best agents from that same set” (2004, p. 16386). The result has been extremely influential (...) as an epistemic justification for diversity policy initiatives. Here we show that the ‘diversity trumps ability’ result is tied to the particular random landscape used in Hong and Page’s simulation. We argue against interpreting results on that random landscape in terms of ‘ability’ or ‘expertise.’ These concepts are better modeled on smother and more realistic landscapes, but keeping other parameters the same those are landscapes on which it is groups of the best performing that do better. Smoother landscapes seem to vindicate both the concept and the value of expertise. Change in other parameters, however, also vindicates diversity. With an increase in the pool of available heuristics, diverse groups again do better. Group dynamics makes a difference as well; simultaneous ‘tournament’ deliberation in a group in place of the ‘relay’ deliberation in Hong and Page’s original model further emphasizes an advantage for diversity. ‘Tournament’ 2 dynamics particularly shows the advantage of mixed groups that include both experts and non-experts. As a whole, our modeling results suggest that relative to problem characteristics and conceptual resources, the wisdom of crowds and the wisdom of the few each have a place. We regard ours as a step toward attempting to calibrate their relative virtues in different modelled contexts of intellectual exploration. (shrink)
