Program

Decisions for submissions to FEW2019 have been made. Out of 86 submissions, we have accepted 20 papers as contributed talks and six more submissions for special format sessions (proof of concept, tutorials).

The conference will be held at the premises of the University of Turin, in three adjacent buildings in the city center:

  • Palazzo del Rettorato (Via Verdi, 8—also accessible from Via Po)
  • Cavallerizza Reale (Via Verdi, 9)
  • Palazzo Badini-Confalonieri (Via Verdi 10)

Below you find the program in chronological order. Regular talks take 60 minutes, including commentary and discussion time. Keynotes, tutorials and proof-of-concept sessions take 75 minutes.

Poster titles, explanations on special sessions (proof-of-concept, tutorials) and abstracts of invited speakers are at the bottom of this page.

Early Social Excursion 1: Trekking in the Alps (in case of good weather only)
Not so Early Social Excursion 2: Something Cultural

Proof-of-Concept Session

The proof-of-concept session presents new approaches to classical problems, often transferred from different (sub)disciplines (e.g., statistics, game theory, ethics). The goal is to enrich the set of methods and techniques in formal epistemology and to bring them to the attention of a wider audience.

Tutorials

We go back to the roots of FEW as a workshop where useful, but perhaps not very familiar techniques are explained. Therefore we have included a tutorial session on the morning of Thursday 20 June.

Abstracts of Invited Speakers

Paul Égré: Justified Approximation

Why is our language vague? One plausible explanation is that in contexts in which a cooperative speaker is not perfectly informed about the world, the use of vague expressions offers an optimal tradeoff between truthfulness and informativeness. In this paper, this hypothesis is substantiated by examining the meaning of the numerical
approximator “around”. We compare the use of “around” with the expression of precise intervals involving “between”, and explain, using a Bayesian model of interpretation, how “around” allows a rational hearer to infer a better probabilistic representation of the uncertain distribution the speaker has in mind, and allows a rational speaker to better communication the uncertain information he or she has in mind.

The talk is based on joint work with A. Mortier, B. Spector, and S. Verheyen.

Stephan Hartmann: The Distance-Based Approach to Bayesianism

Bayesianism is currently our best theory of uncertain reasoning with many applications in philosophy and related fields. In this talk, I will first present the standard approach to Bayesianism which recommends (Jeffrey) conditionalization as the canonical updating method. I will then point out several limitations of the standard approach and propose the distance-based approach to Bayesianism as a remedy. The distance-based approach generalizes the standard approach and has many important applications, such as modeling the learning of conditional information. It also allows us to address “the problem of the algebra”, i.e. the problem of how to specify the new probability distribution after adding a new variable to the algebra. Finally, I apply the distance-based approach to the problem of probability aggregation and show how the proposed methodology can be used to provide a rational justification of the probability weighting functions used in Prospect Theory

Ulrike Hahn: Knowledge from social networks—the Good, the Bad, and the Ugly

Testimony is central to our beliefs about the world, prompting normative concerns about how epistemic agents should respond to the testimony of others. Yet much research on testimony that has considered normative questions has focussed only on dyads: an agent in exchange with a single source. However, those sources are themselves typically part of wider social networks. Examining putative normative strategies for dealing with the testimony of less than fully reliable sources in both individual and collective contexts reveals features of those strategies that would not be apparent in either context alone, and provides reasons for normative re-evaluation. The talk outlines findings from behavioural experiments and agent-based simulations to provide a more in-depth understanding of central intuitions about testimony.
