DESCRIPTION:GERAD Seminar\n\nSpeaker: Cedric Langbort (University of Illino
 is at Urbana-Champaign)\n\n*This is a hybrid event*\n\nZoom Link\n\nAbstra
 ct:\n\nFrom the canonical work of Sobel & Crawford on cheap talk to the mo
 re recent framework of Bayesian Persuasion\, the field of Information Econ
 omics (IE) has produced a number of valuable and insightful models and par
 adigms to explain and study the role of information and communication in d
 ecision-making and strategic interactions.\n\nThe fact that these models s
 pecifically account for intent of the various actors makes them well-suite
 d to address the problem of production\, diffusion and consumption of misi
 nformation in social-media since\, despite popular phrases such as 'misinf
 ormation epidemics' and 'online virality'\, these phenomena are driven as 
 much by human choices and utilities as by contact between 'infected' neigh
 bors...\n\nHowever\, some of the main characteristics of these IE models a
 lso need to be modified and updated to better encapsulate facets of human 
 engagement with information that are peculiar to online (fake) news. Notab
 ly\, 'persuasion' fundamentally assumes that the information receiver is B
 ayesian and fully self-motivated\, which appears at odds with the kind of 
 attention-limited and/or motivated reasoning news consumer of online news 
 identified in some recent large scale studies.\n\nIn this talk we present 
 some such modifications (motivated by control\, information and network th
 eory) and uses of persuasion models in the context of (mis)information pro
 pagation\, covering some of our recent work on almost-bayesianity\, social
 -identity\, interventions and misinformation regulation in strategic situa
 tions.\n\nThis is joint work with grad students Vijeth Hebbar\, Olivier Ma
 ssicot and So Sasaki.\n\nLink to the event\n
