Abstract:
Deliberation often leads to changes in preferences and beliefs of an agent, influenced by the opinions of others, depending on how reliable these agents are according to the agent under consideration. Sometimes, it also leads to changes in the opposite direction, that is, reliability over agents gets updated depending on their preferences and/or beliefs. There are various formal studies of preference and belief change based on reliability and/or trust, but not the other way around $-$ this work contributes to the formal study of the latter aspect, that is, on reliability change based on agent preferences. In process, some policies of preference change based on agent reliabilities are also discussed. A two-dimensional hybrid language is proposed to describe such processes, and axiomatisations and decidability are discussed.
