I never really understood why people can't piece together the information that is presented to them instead of just taking things at face value. Is media literacy not taught at all in schools? You can read anything on the internet and use your rational mind (if you are educated so) to filter out the truths. If you can't verify something just find other sources saying the same thing, at least then perhaps you can work off probabilities/likelihood.
I know many people read on like a 10th grade level, so I guess I see the importance of trust, as those people likely just read headlines and not the content, and definitely don't analyse.
Good answer and I admire your thinking here. I can think of a few times some long held beliefs got debunked or the original studies or articles were retracted.
