Change Your Belief about Belief Change
Éric Grégoire · 2013
Summary form only given. Belief change has long been a major topic of research in artificial intelligence, giving rise to very active subareas of their own, like belief revision, update and knowledge fusion. Much focus has been devoted to belief change in the situations where the incoming information in interaction with the previous available beliefs leads to logical inconsistency. When no logical conflict arises, the new information is just added to the current state of beliefs. On the contrary, we claim that many situations require some change in the pre-existing beliefs in front of an incoming piece of information, even when no logical conflict arises. We claim that the agenda of logic based belief change research should be concerned with these other human reasoning paradigms, too.
