We know stress can lead to changes in genes.dormant genes can go active active genes can go dormant some of these changes might be possible to the next generation. Heritable. There's also indications that trauma causes scarring in the brain.
I found some research that indicates the vast majority of children are born with functioning conscience empathy sympathy and the ability to learn or have other experiences that might interfere.
A lot of people probably have the concept of a fuse. Any electrical wiring fuses help stop fires and or protect the device or the system from over current events. If you ever look inside one that's made of glass you will see all it is is a thin piece of wire to complete the circuit. What it relies on is i^2x r is roughly the heat generated where I is the number of amps are is the ohms or resistance. That metal wire piece that single strand that comprises most glass fuses is size so it will melt and burn away disconnecting when it gets too hot. That equation and a few others help determine what size wire to place in between the terminals of a fuse. That's pretty simplified description but we're not going for every detail here trying to build a metaphor.
Basically there's a fault condition or short too much draw something went wrong it melts it disconnects and the circuit is off. If it's a non replaceable fuse as far as most people are concerned the device is now landfill. In reality a $30 soldering ironmight be all it takes with the addition of a screwdriver to save that $1,000 TV.
But as far as the brain is concerned I think metaphorically speaking when someone comes up in an environment or experiences later extreme stresses outside of what their conscience their sense of morality their sense of fairness tells them if this is repetitive the fuse on those parts of the brain blows
and now you have someone who predatory or otherwise is a danger to interact with.
they likely still have high expectations if they ask for something and or as both of my parents say I get what I want when I want.
But as far as the actual feeling of the relation that I took something from you now you can't eat...they might be able to logically deduce that but it doesn't cause any sick feeling within them they might not care to even attempt to relate what they're doing with what it causes.
When police will stop you from recovering the stolen property without so much as I've seen asking them to knock it off...
Well gee if only I could stop them from stealing from me if only I could make someone else stop doing something is the really only way to stop that because I can't ship money and moving away from them cost money. The other factor that's going to be true there is I'm not doing this to myself I don't think I can say that enough. I cannot choose for them to come and take a felony amount from me. By extension though relative to me they have nearly unlimited disposable income. The odds that anyone in this position can move far enough away from someone else who wants to terrorize them and is also granted the ability to repeatedly steal assets from them or seemingly violated any law or the police try to paint the party with less means as the problem this is extreme torture this is extreme cruelty this is deadly
and if you failed to construct it I realized I didn't fully complete the metaphor. Object generating the fault or reason the fuse would trip is the interactions with the narcissist or possibly just bad times causing bad actions from otherwise okay to good people possibly bad people. You can't really know another person stops you can assume and a lot of people don't realize how obvious they make it but no one cares in those educated enough don't seem to have the power to do anything about it but a lot of people will tell you things like oh you know. Yeah you might think you know you might be right 90% of the time but you still assumed or made an educated past history based guess. You did not know the other person's thought automotive
But traumatic events cause the loading on the circuit of the brain that tends to create a Hydra from empathy sympathy conscience centers and I think eventually they burn out if this condition is held or the fuse to them the links that allow their activation from sensory input to processing in that region refuse their blows. the good news is if we were concerned about this as a people instead of normalizing it there's probably ways to fix that. There's been some studies where they confirmed people had these issues some of them both brain scans and history analysis some better somewhere else but not just hey are you a narcissist you want 50 bucks when do the study there was effort put into determining. They used active brain scans and found that people looking at pictures of faces which normally triggers an emotional response in a neurotypical that didn't happen with narcissist or sociopaths. The hopeful of evidence is some of those studies determined you could get those areas to light up by talking to them to trigger what they would feel if something was done to them in line with emotion they're looking at on the other face. What you sounds complex but really what you're doing is dissociating and creating a habit. Usually for behaviors repeated the wiring required in the brain reinforces it becomes dominant pathway so it might be possible to retrain this.
There's also technologies transcranial magnetic stimulation that rely on a focus magnetic pulse to create the electrical pulse inside the brain with the advantage of you apply it outside. I'm not sure if we can both activate and deactivate with that technology it's one of those things I think is somewhat guarded by patents at the moment. I know I could make one it's basically my spot welding device but would require higher voltage mosfets to get the right current in a short amount of time to generate the needed flux through the coil. I was actually able to find more info on the electrical operating parameters then I was on zactly the capabilities of the machines. but if this can activate regions then that might be even simpler because by controlling where the pulse hits by a placement of the external coil on the scalp or above the scalp you don't have to talk them into the association you can maybe just zap it on while they look at the photo to aid the association
And there's a meta link here that I think indicates it's very feasible. It's something that was done by the Mayo clinic in Rochester Minnesota. It takes people with I don't know the scope of it but nerve damage like severed spine strokes etc and basically tortures the fuck out of them. If they can't move limbs the limbs are repeatedly moved. The theory has long been held that there are pathways that regrow but the main problem is you need to reassociate how that connection how that is all interlinked in the brain. The link can reform but without the brain realizing hey this is the pathway to make that leg move it's the same equivalent it's not there. But it worked on the fact that by moving them and doing it repetitively the little bit of feedback signal generated what eventually recondition hey here's how I make the leg move
It's not quite a $30 soldering iron and a screwdriver but I can build you a transcranial magnetic stimulation device for about $500
