Caveat Auditor: Epistemic Trust and Conflicts of Interest

Abstract

ABSTRACT To place epistemic trust in someone is to take their word for something. Much of the existing literature on epistemic trust concerns epistemic authorities. But as important as authority is to epistemic trust, it pales in comparison to the epistemic importance of conflicts of interests. In economics, we say that buyers shouldn’t take the word of sellers. Caveat emptor: let the buyer beware. I argue for a similar principle in epistemology. Caveat auditor: let the hearer beware. Others often have incentives to testify in ways that are odds with our epistemic goals. Given this, our epistemic trust in others should be calibrated to reflect the epistemically virtuous and perverse incentives of ourselves and others. This basic principle explains the need for epistemic caution in a wide range of applied topics from politics to product reviews to fake news.
