It's a little out of order, but I just wanted to mention that I don't disagree with you, and I don't find your tone dismissive at all! Further, I have no intention of convincing anyone of anything specifically, just raising points of interest. We're just having a fun little back and forth!

Misinformation and falsehoods are as old as time, absolutely. What is new is the lack of trust in the authoritative bodies that would typically provide that ballast of truth, to measure against. People distrust the government (and if what I've read about the history of US politics is true, there might be something to that). They don't typically associate government information with "good" information as they would have in the past. Even official publications are not immune, as per my previous example with vaccinations. Lastly, I believe you and I have the ability to search something and find a suitable result to cut through bad information; at least better than most. Passing the "smell test", if you will. We take that for granted. The vast majority don't realize how to find information effectively. They may search "vaccines cause autism" as a question, but that may very well return many fringe articles with that exact string in it, providing validity to the statement where none was before.

Basically, the game is rigged. We've figured out how to navigate those waters with a reasonable amount of success, but it's a skill we've invested in. Most people do not possess that, and are unwilling to acquire it (those same people that will put in a support ticket before trying literally anything to resolve a technical issue they may be encountering). For them, the information bounty we are enjoying is a minefield of confusion.
