I understand the feeling - I often feel like the world is insane and you are the crazy one for pointing out that something makes no sense and dismissed without even a half-assed hypothesis backing it. Finding out there is a good counterintuitive reason for apparent irrationality is a relief.

I suspect the easiest fix on a personal level is ironically self-selection but certain things are known to exacerbate groupthink like the sense of a threat - annoyingly completely separate from /actual/ threats.
