In my world view, the phrase "People are stupid" explains almost everything. Very few people are actually able to think for themselves. The vast majority are basically just sheep, they think whatever the media, their colleagues, friends etc tell them to think. They don't fact check, they don't think critically, they can't understand a well reasoned argument, they basically just believe things based on how much they like whoever said it. They won't accept evidence that disproves those beliefs.
They don't care about the truth, it's all just about being part of the right herd.
Such a world view will justify any belief, because the internet will give you ample supply of the dumbest, most ill-considered opposition to any belief you hold.
Doesn't guarantee there isn't a steel version of their straw out there that you're deliberately ignoring.
Nobody has time to fact check every single fact we need to act on.
Have you read every single study about the last vaccine you took and what the positives and negatives are and where potential problems are and so on? Of course not, we trust that the experts have done enough. Same with learning physics or driving over a bridge and so many other things.
This just sounds like an im14andthisisdeep rant. Everyone is stupid, except you, of course, who are enlightened and detached from "the herd."
