Abstract

Here we extend the Bala-Goyal framework to include differential levels of trust.  We will discuss how this modification might be used to model groups of scientists making judgments about the reliability of one another's work, and show how introducing trust dynamics can both slow learning and, in some cases, lead to stably polarized outcomes.  We will also discuss how agents learning over multiple domains can come to form epistemic factions, where unrelated beliefs become correlated.
