I guess "mental illness" needs to be defined. It seems we may be talking about trends, copycat behavior, influence and such, rather than actual mental illness.
Jim Jones as an example. Were his followers "mentally ill" or simply misguided / suffering a lapse of judgment, having a Neptune transit, etc.
I think if you already have an inkling of mental illness and something triggers it or in the Jim Jones case, someone comes along and validates you in a way to where you finally feel "seen" then, yes.
I feel a lot of people feel lost in life and in certain cases that could lead to mental illness like depression, anxiety. Or if they were born with a mental illness like bipolarism or DID.
Most people are looking to be guided to the meaning of life and why things are the way they are. So maybe it's a lack of faith that causes the misguidance.
Some charming character comes along or some idea and you finally feel understood. You feel home. Some people wake up from the fog (if they've been fooled) or they...drink the kool-aid.
Just like insanity can be contagious, I think also faith can too.. if you're willing to be open to it. And maybe that's where it all stems from, a willingness.
I don't know. Interesting to think about.
Not sure if it made the national news, but there was a horrific ambush of police officers in Florida last week. A family called police on an unhinged "religious fanatic" neighbor who they said was trying to lure them to her home to kill them. After subduing her, deputies walked to her house to check on her family. After no response, upon entering her house her husband and two grown daughters opened fire, killing one and wounding two more, then killing themselves. The woman has shown no remorse, said she wanted to kill as many as possible. How does a whole family become murderously insane?
The answer to this question, I believe, can be seen in operant and classical conditioning.
Some may not know that their behaviors lead to them or others obtaining some sort of a mental illness, some however certainly do know.
The military deploys men after they are taught extreme tactics when engaging with the "enemy". These very tactics were learned alongside psychologists. Other tactics/trainings are deployed without their knowledge and hide in plain sight.
Families can certainly pass on some behaviors. Not everyone is susceptible. I have internally experienced a pull in some very dark directions while simultaneously knowing where this will lead. I did not succumb, others did.
The subjective experience is very real. Feelings count, so long as one is sincere about it. Energies are palpable, and one has the option to ingest and envelope oneself in it or not. Children are obviously a different matter.
Nietzsche has a fitting quote which is "...if you gaze for long into an abyss, the abyss gazes also into you".
I think in addition to the behavioural/conditioning contributors, biology may play a role; Eg The McClintock effect: where female pheromones communicate with each other and menstrual cycles are synchronised.
I think mental/emotional states are more transmissible than we may realise. Biology/ hormones are very powerful behavioural influences.
where female pheromones communicate with each other and menstrual cycles are synchronised.
There's something to this. Women go crazy, together as do men? I'm thinking of a gang mentality.
