Neste ensaio, eu analisarei criticamente três definições de boato. Na primeira seção, eu considerarei a explicação de C. A. J. Coady, na qual o boato é um caso de testemunho aparente, mas não é um caso de testemunho genuíno. Na segunda seção, eu considerarei a definição de boato oferecida por David Coady, na qual o boato se espalha em uma larga cadeia sem status oficial. Na terceira seção, eu considerarei a definição de boato de Axel Gelfert, na qual o boato (...) não tem corroboração independente de evidência de primeira mão ou de fonte oficial. Na quarta e última seção, eu proporei uma definição, na qual o boato é um caso de testemunho genuíno sem confirmação oficial, cuja fonte original foi perdida ou nunca existiu. (shrink)

Gossip has been the object of a number of different studies in the past 50 years, rehabilitating it not only as something worth being studied, but also as a pivotal informational and social structure of human cognition: Dunbar (Rev Gen Psychol 8(2):100–110, 2004) interestingly linked the emergence of language to nothing less than its ability to afford gossip. Different facets of gossip were analyzed by anthropologists, linguists, psychologists and philosophers, but few attempts were made to frame gossip within an epistemological (...) framework (for instance Ayim in (Good gossip, pp. 85–99, 1994)). Our intention in this paper is to provide a consistent epistemological (applied and social) account of gossip, understood as broadly evaluative talk between two or more people, comfortably acquainted between each other, about an absent third party they are both at least acquainted with. Hence, relying on the most recent multidisciplinary literature about the topic, the first part of this paper will concern the epistemic dynamics of gossip: whereas the sociobiological tradition individuates in gossip the clue for the (theoretically cumbersome) group mind and group-level adaptations Wilson et al. (The evolution of cognition, pp. 347–365, 2002), we will suggest the more parsimonious modeling of gossip as a soft-assembled epistemic synergy, understood as a function-dominant interaction able to project a higher organizational level—in our case, the group as group-of-gossips. We will argue that the aim of this synergy is indeed to update a Knowledge Base of social information between the group (as a projected whole) and its members. The second and third part will instead focus on the epistemological labeling of the inferences characterizing gossip: our contention is that the ever-present moral/evaluative dimension in gossip—be it tacit or explicit, concerning the objects or the partners of gossip—is best analyzed through the epistemological framework of abduction. Consequently, we will suggest that a significant role of gossip is to function as a group-based abductive appraisal of social matter, enacted at various levels. (shrink)

This article aims to provide a coherent and comprehensive theoretical framework of the main socio-epistemic features of social media. The first part consists of a concise discussion of the main epistemic consequences of personalised information filtering, with a focus on echo chambers and their many different implications. The middle section instead hosts an analytical investigation of the cognitive and epistemic environments of these platforms aimed at establishing whether, and to what extent, they allow their users to be epistemically vigilant with (...) respect to their sources and the content recommended to them. Finally, in the last part, of a more exquisitely normative nature, some strategies are proposed and discussed that, by reducing the epistemic opacity of social media, could contribute to greater epistemic justice within social media and, concurrently, to augmenting the epistemic autonomy of users.

My main aim in this paper is to examine whether gossip should be categorized as an epistemically valuable character trait. Gossip satisfies the necessary and jointly sufficient conditions for an acquired character trait to be classified as an intellectual virtue under the responsibilist understanding of the concept of virtue. The excellent gossiper is motivated to acquire epistemic goods through gossiping, reliably successful in acquiring epistemic goods through gossiping, competent at the activity of gossiping and good at judging when, with whom (...) and what to gossip. Nonetheless, I show that the excellent gossiper inflicts epistemic wrong on others. The excellent gossiper comes to intentionally acquire another person’s private information without their consent. This leaves virtue responsibilists with three options: resist my argument that gossip qualifies as a responsibilist virtue and/or that excellent gossiping inflicts epistemic wrong, bite the bullet and argue that the intellectually virtuous agent sometimes inflicts epistemic wrong on other agents intentionally, develop a no-wrong principle that disqualifies gossip from being categorized as an intellectual virtue.

Hearsay or indirect testimony receives little discussion even today in epistemology, and yet it represents one of the cardinal modes for the transmission of knowledge and for human cognitive development. It suffices to think of school education whereby a student listens to teachers reporting knowledge acquired, often indirectly, from the most varied sources such as text books, newspapers, personal memory, television, etc… Or let us consider the importance of oral tradition in the social and cultural development of civilisations. Or even (...) let us call to mind the learning process of infants who, only thanks to the knowledge learned from others, succeed in learning the language. Finally, with the emerging digital technology, the information gleaned from third parties is influencing the creation of knowledge in a full gamut of fields, in a quasi-comprehensive manner. This leads us to claim that hearsay, despite the reductionist conceptual scheme to which epistemology has confined it in that indirect testimony, is in any case quintessential in the dissemination of knowledge. This work fully expounds upon the basic mechanism of indirect testimonial transmission and provides an epistemologically founded explanation of the cognitive possibilities of hearsay by investigating, in the light of the anti-reductionist paradigm, three mutually connected epistemic properties, namely trust, reputation and coherence, that are key in the epistemic justification of the truth acquired via an indirect testimony.

Our main aim in this paper is to contribute towards a better understanding of the epistemology of absence-based inferences. Many absence-based inferences are classified as fallacies. There are exceptions, however. We investigate what features make absence-based inferences epistemically good or reliable. In Section 2 we present Sanford Goldberg’s account of the reliability of absence-based inference, introducing the central notion of epistemic coverage. In Section 3 we approach the idea of epistemic coverage through a comparison of alethic and evidential principles. The (...) Equivalence Schema–a well-known alethic principle–says that it is true that $p$ if and only if $p$ . We take epistemic coverage to underwrite a suitably qualified evidential analogue of the Equivalence Schema: for a high proportion of values of $p$ , subject $S$ has evidence that $p$ due to her reliance on source $S^{*}$ if and only if $p$ . We show how this evidential version of the Equivalence Schema suffices for the reliability of certain absence-based inferences. Section 4 is dedicated to exploring consequences of the Evidential Equivalence Schema. The slogan ‘absence of evidence is evidence of absence’ has received a lot of bad press. More elaborately, what has received a lot of bad press is something like the following idea: absence of evidence sufficiently good to justify belief in $p$ is evidence sufficiently good to justify belief in $\sim p$ . A striking consequence of the Evidential Equivalence Schema is that absence of evidence sufficiently good to justify belief in p is evidence sufficiently good to justify belief in $\sim p$ . We establish this claim in Section 4 and show how this supports the reliability of an additional type of absence-based inference. Section 4 immediately raises the following question: how can we make philosophically good sense of the idea that absence of evidence is evidence of absence? We address this question in Section 5. Section 6 contains some summary remarks. (shrink)
