It is an odd phenomenon among humans that I at least don’t quite understand, the seeming tendency to ignore or dismiss possibilities of proven negative outcomes … for whatever reason. “I know all those other conspiracies I dismissed all turned out to be true, but I am sure I would know if there were any additional conspiracies” … totally ignoring one’s track record.
It appears to be the same kind of mentality of “hey, you know who we should trust with our lives … the government made up of people who lie to us, steal from us, and mass murder on a regular basis; that’s who we should give control over to.”
People conspire, I’ve witnessed it personally numerous times; sometimes for greedy business reasons, at other times to mass murder and commit genocide on a scale not seen since. Humans conspire, even if sometimes only because they’re not prevented from doing so naturally.
