I don't know if that's a new thing or not, but that's how it has seemed to me during this pandemic.
Quite a few people have gone without an easy, safe, miraculously effective vaccine - a marvel of the latest science, freely available at their fingertips - and literally died. As far as I can tell, their deepest motivation to do this was to express their distrust of the establishment and/or stick it to their political opponents.
In a "lol nothing matters" world, all that matters to these people is whether they get to stick it to the man. Nothing bad can really happen, so no real thought is needed to stay safe. It's fine to just believe the first entertainingly outrageous quack theory that flatters your sentiments or ideology or tribe.
It's as if they were interrupted by a gunman while watching TV, and made no motion to defend themselves, assuming the gun pointed at their heads was part of the show.
