Philosophy, and more specifically, epistemology is one of the most important disciplines in the world and it would do a lot to help our societal discourse if people studied it from an early age. Most people never ask the questions of what knowledge actually is and what constitutes knowing something vs assuming something vs motivated reasoning, bias, etc.

I know that many people don't care about Knowledge™ and are more motivated by winning but perhaps it would be easier to counter these people if the language of knowledge was more broadly spoken, understood, and internalized.
