Metaphysics and Epistemology Group (Tuesday - Week 2, HT25)

Abstract: Is it ever rational to change your mind based on others changing theirs? This talk answers affirmatively. Changes of mind are doubly epistemically significant. First, they provide compelling reasons for further inquiry. Second, they offer second-order evidence about the existence or quality of first-order evidence. However, critical evaluation is crucial to distinguish meaningful changes from irrelevant ones. By outlining key questions about reported changes and discussing potential pitfalls, we can better identify which changes are epistemically significant. If correct, my proposal highlights mind-changing as a valuable yet overlooked source of information when exploring complex and contentious issues.
