There are tropes commonly used in cosmic horror works that boil down to the following idea. A human mind when faced with something utterly incomprehensible may break into insanity and never get back to sanity.
For sure, this is just works of fiction and most likely they have exaggerated something that may actually happen in the reality. For example, if a person learns about some big dangers that may happen in the future, it may cause an extreme anxiety in them, which can cause them to be unable to live a normal live or behave in normal ways. Yet, that may very well depend on the persons' predisposition, and some other person learning about the very same fact may react in much less caring way.
Hence, my question is the following. Do our minds indeed have a common mechanism that will cause most of humans lose sanity when faced with some information way hard for it to comprehend?
To be more precise, by insanity I do not mean any particular mental illness, but rather a set of behaviors that do not allow a person to sustain themselves, be a part of the society and overall reduce their chances of survival.
Ideally, examples would comprise
- a revelation: a new piece of information that becomes available to a person
- a reaction: once relevation sinks in (matter of less than a day) a person goes insane with no chance of recovery
I guess a proper search would start with the effects that an immediate (psychological only) stress may have on a human mind, but I was not able to find anything as drastic.
