Mandevillian intelligence is a specific form of collective intelligence in which individual cognitive shortcomings, limitations and biases play a positive functional role in yielding various forms of collective cognitive success. When this idea is transposed to the epistemological domain, mandevillian intelligence emerges as the idea that individual forms of intellectual vice may, on occasion, support the epistemic performance of some form of multi-agent ensemble, such as a socio-epistemic system, a collective doxastic agent, or an epistemic group agent. As a specific (...) form of collective intelligence, mandevillian intelligence is relevant to a number of debates in social epistemology, especially those that seek to understand how group (or collective) knowledge arises from the interactions between a collection of individual epistemic agents. Beyond this, however, mandevillian intelligence raises issues that are relevant to the research agendas of both virtue epistemology and applied epistemology. From a virtue epistemological perspective, mandevillian intelligence encourages us to adopt a relativistic conception of intellectual vice/virtue, enabling us to see how individual forms of intellectual vice may (sometimes) be relevant to collective forms of intellectual virtue. In addition, mandevillian intelligence is relevant to the nascent sub-discipline of applied epistemology. In particular, mandevillian intelligence forces us see the potential epistemic value of (e.g., technological) interventions that create, maintain or promote individual forms of intellectual vice.

Emotions have long been of interest to philosophers and have deep historical roots going back to the Ancients. They have also become one of the most exciting areas of current research in philosophy, the cognitive sciences, and beyond. -/- This book explains the philosophy of the emotions, structuring the investigation around seven fundamental questions: What are emotions? Are emotions natural kinds? Do animals have emotions? Are emotions epistemically valuable? Are emotions the foundation for value and morality? Are emotions the basis (...) for responsibility? Do emotions make us better people? -/- In the course of exploring these questions, the book also discusses cutting-edge empirical research on emotion, feminist approaches to emotions and their value, and methodological questions on how to theorize about the emotions. The book also contains in-depth discussions of specific emotions like compassion, disgust, anxiety, and curiosity. It also highlights emerging trends in emotion research. (shrink)

ABSTRACT People suffer from a variety of cognitive shortcomings when forming and updating their political beliefs. Three pervasive shortcomings are confirmation bias, disconfirmation bias, and motivated reasoning. The emotional state of anxiety can help us overcome these biases given the open-minded, information-rich, reflective deliberation with diverse people it may promote—although mass and social media may hinder this type of deliberation.

In the philosophy of science, it is a common proposal that values are illegitimate in science and should be counteracted whenever they drive inquiry to the confirmation of predetermined conclusions. Drawing on recent cognitive scientific research on human reasoning and confirmation bias, I argue that this view should be rejected. Advocates of it have overlooked that values that drive inquiry to the confirmation of predetermined conclusions can contribute to the reliability of scientific inquiry at the group level even when they (...) negatively affect an individual’s cognition. This casts doubt on the proposal that such values should always be illegitimate in science. It also suggests that advocates of that proposal assume a narrow, individualistic account of science that threatens to undermine their own project of ensuring reliable belief formation in science.

It has recently been suggested that politically motivated cognition leads progressive individuals to form beliefs that underestimate real differences between social groups and to process information selectively to support these beliefs and an egalitarian outlook. I contend that this tendency, which I shall call ‘egalitarian confirmation bias’, is often ‘Mandevillian’ in nature. That is, while it is epistemically problematic in one’s own cognition, it often has effects that significantly improve other people’s truth tracking, especially that of stigmatized individuals in academia. (...) Due to its Mandevillian character, egalitarian confirmation bias isn’t only epistemically but also ethically beneficial, as it helps decrease social injustice. Moreover, since egalitarian confirmation bias has Mandevillian effects especially in academia, and since progressives are particularly likely to display the bias, there is an epistemic reason for maintaining the often-noted political majority of progressives in academia. That is, while many researchers hold that diversity in academia is epistemically beneficial because it helps reduce bias, I argue that precisely because political diversity would help reduce egalitarian confirmation bias, it would in fact in one important sense be epistemically costly.

The role intellectual virtues play in scientific inquiry has raised significant discussions in the recent literature. A number of authors have recently explored the link between virtue epistemology and philosophy of science with the aim to show whether epistemic virtues can contribute to the resolution of the problem of theory choice. This paper analyses how intellectual virtues can be beneficial for successful resolution of theory choice. We explore the role of virtues as well as vices in scientific inquiry and their (...) beneficial effects in the context of theory choice. We argue that vices can play a role in widening the set of potential candidate theories and support our claim with historical examples and normative arguments from formal social epistemology. We argue that even though virtues appear to be neither necessary nor sufficient for scientific success, they have a positive effect because they accelerate successful convergence amongst scientists in theory choice situations.

There is a clean image of knowledge transmission between thinkers that involves sincere and reliable speakers, and hearers who carefully assess the epistemic credentials of the testimony that they hear. There is, however, a murkier side to testimonial exchange where deception and lies hold sway. Such mendacity leads to sceptical worries and to discussion of epistemic vice. Here, though, I explore cases where deceit and lies are involved in knowledge transmission. This may sound surprising or even incoherent since lying usually (...) involves saying something that is false. Even if a liar unwittingly tells the truth, those believing their testimony would not acquire knowledge. In §1, however, I suggest a range of examples where lies can be used to transmit knowledge. The kinds of cases upon which I focus are those involving ‘engineered knowledge’, where a speaker skilfully manipulates another into having a true belief. Such cases are epistemologically significant for several reasons. First, they are counter-examples to a range of widely held assumptions about knowledge. We have, for example, cases where sincerity is not necessary for knowledge transmission, where there is knowledge from falsehood, and, as we shall discuss in §2, knowledge that is fragile or not safe. Second, in §3 and §4 I suggest that engineered knowledge is best captured by a virtue theoretic approach to testimonial transmission. (shrink)

This paper explores the role of phenomenology in the understanding of the cognitive processes of coupling/decoupling, defending the Wittgensteinian idea that phenomenology can play a crucial role as a description of immediate (social) experience. We argue that epistemic feelings can provide a phenomenological description of the development of a subject's everyday experience, tracking the transition from the processes of coupling/decoupling and recoupling with the world. In particular, the feeling of familiarity, whose key features can be considered the core of epistemic (...) feelings, signals a novelty in the flow of experience that makes sense and is worthy of remarking on or even articulating. By describing the primary features and sources of the feeling of familiarity, we highlight a conceptual tension related to its sources, which could be based on processing both fluency and discrepancy. We proposed a solution to the conceptual tension by introducing two levels of the feeling of familiarity: epistemic and experiential. (shrink)

Vice essentialism is the view that epistemic vices have robustly negative effects on our epistemic projects. Essentialists believe that the manifestation of epistemic vices can explain many of our epistemic failures, but few, if any, of our epistemic successes. The purpose of this paper is to argue that vice essentialism is false. In §1, I review the case that some epistemic vices, such as closed-mindedness and extreme epistemic deference, have considerably beneficial effects when manifested in collectivist contexts. In §2, I (...) add that there are putative epistemic vices whose repeated manifestation leads to significant epistemic achievements over time. Epistemic recklessness is one such unstable vice. Though Sosa argues that epistemically reckless judgements cannot constitute knowing full well, the repeated manifestation of epistemic recklessness is essential to our becoming fully well knowledgeable in the long run. Without making incompetent judgements in environments that offer unambiguous, actionable feedback, we could not develop the intuitive and reflective competences and meta-competences required for knowing full well.

Is closed-mindedness always an intellectual vice? Are there conditions in which it might be an intellectual virtue? This paper adopts a working analysis of closed-mindedness as an unwillingness or inability to engage seriously with relevant intellectual options. In standard cases, closed-mindedness will be an intellectual vice. But, in epistemically hostile environments, closed-mindedness will be an intellectual virtue.

Studies in collective intelligence have shown that suboptimal cognitive traits of individuals can lead a group to succeed in a collective cognitive task, in recent literature this is called mandevillian intelligence. Analogically, as Mandeville has suggested, the moral vices of individuals can sometimes also lead to collective good. I suggest that this mandevillian morality can happen in many ways in collaborative activities. Mandevillian morality presents a challenge for normative virtue theories in ethics. The core of the problem is that mandevillian (...) morality implies that individual vice is, in some cases, valuable. However, normative virtue theories generally see vice as disvaluable. A consequence of this is that virtue theories struggle to account for the good that can emerge in a collective. I argue that normative virtue theories can in fact accommodate for mandevillian emergent good. I put forward three distinctive features that allow a virtue theory to do so: a distinction between individual and group virtues, a distinction between motivational and teleological virtues, and an acknowledgement of the normativity of “vicious” roles in groups.
