There's also a feeling of "knowing" more than other people. You don't know about how Albert Einstein and Nikola Tesla invented a time traveling aircraft carrier? Have I got some research that you need to do on your own. But if you did know about it, then it's junk meant to distract you from what's really going on.

None of that "knowledge" derives from any level of credible sources, but it does bring a certain level of superiority over people on Facebook. If it's actually well documented and widely known, then that isn't something where I get to feel better than other people.
