This is why I think epistemology is so important. Thinking through how we come about claiming to have knowledge about something is so important. Does it involved reason, logic, and evidence with an appropriate amount of skepticism? Then maybe we can talk with a bit more confidence and, importantly, we can transfer that information to someone else in a way they can understand it.

Without a good epistemology, people believe all kinds of random stuff which shapes their thoughts and actions if very destructive ways by those who know how to predict outputs given a worldview and a set of programmed inputs.
