DESCRIPTION:Abstract: I present some applications 
 of logical methods (in particular, of so-called dy
 namic epistemic logics) to the study of emergent p
 henomena in groups of `agents', capable of reflect
 ion, communication, reasoning, argumentation etc.T
 he main focus on the understanding of belief/prefe
 rence formation and diffusion in social networks, 
 and on how this affects the group's ``epistemic po
 tential": the ability of the agents to track the t
 ruth of the matter (with respect to some given rel
 evant topic). While in some cases, ``wisdom of the
  crowds" can increase the epistemic potential, in 
 other situations the group's dynamics leads to inf
 ormational distortions (-- the ``madness of the cr
 owds": cascades, ``groupthink", the curse of the c
 ommittee, pluralistic ignorance, group polarizatio
 n, doxastic cycles etc). I explain how logic (in c
 ombination with probabilistic methods) can be used
  to provide some explanations for both types of si
 tuations, as well as to suggest some partial solut
 ions to informational distortions.
X-ALT-DESC;FMTTYPE=text/html:\n  <p>Abstract: I pr
 esent some applications of logical methods (in par
 ticular, of so-called dynamic epistemic logics) to
  the study of emergent phenomena in groups of `age
 nts', capable of reflection, communication, reason
 ing, argumentation etc.The main focus on the under
 standing of belief/preference formation and diffus
 ion in social networks, and on how this affects th
 e group's ``epistemic potential&quot;: the ability
  of the agents to track the truth of the matter (w
 ith respect to some given relevant topic). While i
 n some cases, ``wisdom of the crowds&quot; can inc
 rease the epistemic potential, in other situations
  the group's dynamics leads to informational disto
 rtions (-- the ``madness of the crowds&quot;: casc
 ades, ``groupthink&quot;, the curse of the committ
 ee, pluralistic ignorance, group polarization, dox
 astic cycles etc). I explain how logic (in combina
 tion with probabilistic methods) can be used to pr
 ovide some explanations for both types of situatio
 ns, as well as to suggest some partial solutions t
 o informational distortions.</p>\n
