The conclusion is terrifying in my opinion. A not yet explained phenomenon or even something as far fetched as "aliens" would have been a more comforting answer than "essentially we can all start losing our mind at once, and it takes very little to trigger it".
It's not terrifying. It's how people are, and it's destressing to me that so few people seem to be aware of it. No amount of explaining what confirmation bias is will convince people that drones in the sky aren't aliens. The people who have looked behind the curtain and come to this realization about people and their behavior tend to be the ones who make the skeptic community, so we have that going for us at least.
Combined with the inherent anti intellectual bias of most of America inherited from the nerd hatred of us high schools, reality has no chance against fantasy.
Look at how newspapers treat science. Findings are held up like a freak zoo of "look at what the weirdo science nerds are saying now" as they sensationalize and warp things in the desperate need for clickbait.
So combine pseudoreality rules of media with pseudoreality of finance and economics, and the pseudoreality of politics, and reality simple doesn't have a chance.
