I’m not interested in what the dictionary says or a textbook definition I’m interested in your personal distinction between the two ideas. How do you decide to put an idea in one category versus the other? I’m not interested in the abstract concepts like ‘objective truth’ I want to know how it works in real life for you.
It sounds like you’re interested in epistemology. Take a dive into this Wikipedia article and give at least the parts on Justified True Beliefs a read.
