Haven't read enough of it either, so I won't comment on that part, but you're definitely right about the information regarding the modern era. You only need to take one look at the mental health district to understand that - outside of it being a business like any other is - one of its primary goals is reality consensus enforcement.
This isn't to say that there aren't dangerous people out there with psychological issues that make them detrimental to society, but - as was stated in one of my favourite pieces of fiction and fits my own beliefs - 'the stereotype of the shifty-eyed serial killer is very much a Hollywood invention' in a lot of regards -- many psychopaths are excellent liars, superficially charming, and appear completely normal to most people. The people who looks dangerous are not always the ones you need to be careful of, and it's a really bad misconception that social awkwardness automatically means dangerous. It's also an illusion to believe thinking outside the box means you're 'wrong' or automatically 'irrational' and 'illogical'.
As science progresses, so does the ability to brainwash people. The belief that only older societies cover up or remove elements that they dislike - and subsequently the belief that modern society is more rooted in 'the truth' than more old-fashioned times - is very much an illusion. The lies still exist, and it's simply the 'content' of the lies that changes and the methods used to represent them. For example, a lot of people who would be made outcasts in this era by being called 'insane' would have simply been considered 'demonically possessed' prior to the introduction of science becoming the new world's method of propaganda and replacing religion.
Peer pressure is another big cause of alienation, but that's been going on throughout all of history too.
Would like to chime in, as I am studying criminology at the moment.
If we are looking at mental health related to, for example, serial killers like you brought up.. this is like the iceberg. Killing and murder are high profile crimes that typically attract all kind of weirdos.
You have to be some level of unstable to be capable of killing someone. But another interesting point that was brought up
that fits with your analogy of the shifty eyed serial killer is that in fact, if you look at corporate crime, people that typically indulge in corporate crime fit all of the criteria to be labeled a psychopath. I think this can be furthered to the point where we might also call politicians 'career psychopaths' at this point. Especially in America, where the line between corporatism and presidency/politics is often very skewed and grey.
@Vilageidiotx can surely agree with the fact that politicians are often also in the borderline-psychopath regions in regards to how they act.
The key difference is that it is much more hidden, because like you said, these people are charming and they typically know exactly what to say in order to avoid 'detection' so to speak. Furthermore, the effects of their psychopathic nature are either seen as a) belonging to the job
a lรก, you have to be ruthless and unsympathetic to run a country/corporation or b) not noticed because they are so charismatic.
Now on the other hand I am also of the opinion that our obsession with labels is causing us to go ever so slightly insane and has a lot of bad health effects. For example, a lot of ADHD or ADD diagnoses are merely children that have a lack of concentration or are just 'busy' because that's how their personality is.
I find that a lot of people that have ADHD typically do not really have it, but are just very excitable people. I'm not sure on the statistics, but I think there is a gross over-diagnosis of these type of mental disorders (if we could even call them that, they're quite harmless) because these disorders are 'easy to diagnose'.
So, the observation that we are fascinated and obsessed by labeling things might be very true, and not positive whatsoever.
