>Except for first hand experience on a subject, you will never be able to find a source that is inherently trustable

Even first hand experience isn't trustworthy. Our memory is so deeply flawed that I can't even tell with certainty which first-hand experiences I had. Simply presenting "evidence" that you should remember something can cause your brain to make that memory up. And if the experience is genuine and and I try to remember some detail I didn't pay close attention to, my brain will most likely just make it up. So the only reliable way to learn from personal experience is to learn during the experience, but confirmation bias will make me miss most opportunities to learn.

Honestly, it's amazing that we are capable of learning at all.
