The truth about this is that all human beings live our lives as much as possible in accordance to what we believe, have been taught, our own conclusions, etc., and thus also in accordance to the expectations that follow thereof. And this is no different for Psychopaths.
Yes, I know I'm saying I am not a Psychopath, but I am human and so are Psychopaths, and that means what I say above applies to Psychopaths as does it to every single individual (with perhaps the exception of the most rare of all: The ultimately enlightened deeply initiated Occultist/Religious Person).
I've noticed that many of those who consider themselves psychopaths, Sociopaths and Antisocial - and who very often likely are Antisocial or at least Sociopaths - have a tendency to believe that our lesser emotionality (this being a trait, like so many others, that I share with Psychopaths) which enables us to keep a sharper focus and see more details as well as get a more efficient view over the whole picture, ...that this means we can 'see' and 'understand' reality clearly and completely, as it 'really' is.
To me it is fairly obvious that those who do in reality take this position are no less deluded than the general public, and I know some will likely disagree and perhaps take a less positive stand towards this statement of mine.
I will explain what I see from a wider perspective, including what I think is really the case here:
Many Psychopaths sometimes give statements of a nature such as this:
"The Victim is ruled by emotions, emotions cloud their vision and ability to achieve a clear perception, whereas we/I can view the situation unvarnished by emotional clutter, and I therefore see things as they really are, the weaknesses in the victim are therefore apparent and I easily make the conclusions about how things Really are!"
My claim is that the intelligent Psychopath have no illusions of being able to see anything 'clearly', of seeing things as 'they really are'. What 'we' are instead doing - what we're really doing when we say such things - is giving - or trying to be giving - the impression that we have knowledge about everything; we use our very knowledge that the human psyche act and reacts - physically and psychologically - in accordance to what they believe and expect.
If you believe that I know a lot and that I know much more than you do, you'll be more likely to believe whatever I say is the truth at a later point - that point, when I've worked an individual into a certain spot where I want them to be ... that special spot where they're emotionally and mentally weakened, vulnerably open and therefore susceptible to a statement put forth by me in a dominant and confident matter-of-fact like manner. It is the situation I could call 'A Soil well prepared and ready for the Seeds of my choosing to be sown' ... then I can give any statement and call it The Truth, and the victim will believe me, even if I do not.
And to be matter-of-fact like: I do not believe my statements in these situations. It does not matter if they're true or not, what matters is their impact upon the individual (or 'victim', if you prefer the more dramatic verb) I am saying these things to.
This is what intelligent Psychopaths are doing, I'm absolutely certain of it. And it works because we're good at giving the impression of having 'second sight'-like abilities.
