Title:  The Nature and Rationality of Disagreement

Abstract:

In his most cited paper, Nobel prize winner Robert Aumann (Economics,  
2005) showed thirty years ago that Bayesians with a common prior  
could not "agree to disagree."  That is, they could not have common  
knowledge of exact yet differing opinions.   Aumann made strong  
assumptions, but his basic result holds under much weaker  
assumptions.   We now have relatively general and robust results to  
the effect that honest truth-seeking agents should not knowingly  
disagree.   At least they should not disagree when they disapprove of  
self-favoring initial (i.e., low-information) expectations, or  
believe that such expectations had symmetric origins.   Professor  
Hanson will review this literature and discuss its disturbing  
implications for the honesty and rationality of human disagreement.

***The talk will be followed by refreshments in Ryerson 255***
