Argumentation and exchange of information help groups to coordinate, deliberate and decide. On the other hand, debates often generate detrimental large-scale phenomena such as polarization, informational cascades and echo-chambers, where the behavior of entire groups shifts in seemingly irrational ways.

Understanding the deep mechanisms of informational and social influence that underlie these phenomena in the age of social media is a challenge that engages methods from different disciplines, including philosophy, artificial intelligence, computer and social sciences and psychology. Formal methods from argumentation theory, logic and Bayesian epistemology provide prominent tools to explore this area and to ground data analysis, experimental work and multi-agent social simulations.

This workshop brings together scholars with different theoretical approaches. Its broader aim is to foster an interdisciplinary understanding of the mechanisms that determine the behavior of individuals in a social context from multiple perspectives. The workshop will last two and a half days. The first half-day of it will be dedicated to an introductory seminar on abstract argumentation, held by Professor Pietro Baroni (Brescia).

The workshop is promoted by the project EDAPOL - The Epistemic and Dynamic Aspects of Polarization, a Marie Skłodowska-Curie Individual Fellowship (H2020-MSCA-IF-2016, nr. 748421) funded by the European Commission.

It may be of interest to signal that, after this event, a workshop on Formal Models of Deliberation and Polarization will be organised at VU, Amsterdam on 2 – 3 April by Prof. Catarina Dutilh Novaes and Dr. Hein Duijf.

Invited speakers:

  • Pietro Baroni (University of Brescia, IT)
  • Marcello D’Agostino (University of Milan, IT)
  • Catarina Dutilh Novaes (VU Amsterdam, NED)
  • Michael Mäs (University of Groningen, NED)
  • Henry Prakken (Utrecht University, University of Groningen, NED)
  • Alice Toniolo (University of St Andrews, UK)
  • Rineke Verbrugge (University of Groningen, NED)
  • Jean Wagemans (University of Amsterdam, NED)


Submissions are invited on the general field of argumentation theory, logic and formal epistemology, including, but not restricted to

  • Abstract and structured argumentation
  • Dynamic epistemic logics for correlated information change
  • Logical aspects of argumentation
  • Informal logic
  • Bayesian epistemology
  • Computational approaches to argumentation, social choice and deliberation in multi-agent networks
