Yeah, this is an evolutionary adaptation. Even long ago the world had too many stimulus and we develop patters of how to handle different types of situations. This is talked about extensively in the book, "Thinking, fast and slow". In today's world, the world is infinitely complex. No one has time (or the desire, frankly) to do appropriate research on a single issue let alone all the issues that need considered. I'd bet that almost no one did 20+ hours of research reading about mRNA vaccines and FDA clinical trial data before decided to take or not take the vaccine. Everyone picked someone to trust whether that was the FDA or social media or news media and then got on with their life. And generally, once we find a "trusted" source, we tend to trust them for everything regardless of lack of evidence or contradiction. Humans have a deep survival instinct of having packs and trusting in the pack to protect them. Everyone just wants to get on with their busy life and not have to worry about all of this, whatever it is.
