I think you're right, but you're missing the point : There's nothing easy or instantaneous about knowing whether or not a fact is genuine. People can lie, can lie by omission, can try to influence your opinion by choosing carefully how they present the facts, and so on. You can always choose to trust some people/institutions, but that's trusting/believing, not knowing.

I don't believe I'm missing the point. You seem to be assuming that people are incapable of observing/verifying/creating their own facts. I don't see that being implied in this comment chain, and it's definitely not true.
