I think some of this is quite true:
"Psychopaths make their way by conning people into doing things for them; obtaining money for them, prestige, power, or even standing up for them when others try to expose them. But that is their claim to fame. That's what they do. And they do it very well. What's more, the job is very easy because most people are gullible with an unshakable belief in the inherent goodness of man.
Manipulation is the key to the psychopath's conquests. Initially, the psychopath will feign false emotions to create empathy, and many of them study the tricks that can be employed by the empathy technique. Psychopaths are often able to incite pity from people because they seem like "lost souls" as Guggenbuhl-Craig writes. So the pity factor is one reason why victims often fall for these "poor" people.
Psychologist Robert Hare cites a famous case where a psychopath was "Man of the Year" and president of the Chamber of Commerce in his small town. (Remember that John Wayne Gacy was running for Jaycee President at the very time of his first murder conviction!) The man in question had claimed to have a Ph.D. from Berkeley. He ran for a position on the school board which he then planned to parlay into a position on the county commission which paid more.
At some point, a local reporter suddenly had the idea to check up on the guy - to see if his credentials were real. What the reporter found out was that the only thing that was true about this up and coming politician's "faked bio" was the place and date of birth. Everything else was fictitious. Not only was the man a complete impostor, he had a long history of antisocial behavior, fraud, impersonation, and imprisonment. His only contact with a university was a series of extension courses by mail that he took while in Leavenworth Federal Penitentiary. What is even more amazing is the fact that before he was a con-man, he was a "con-boy." For two decades he had dodged his way across America one step ahead of those he had hoodwinked. Along the way he had married three women and had four children, and he didn't even know what had happened to them. And now, he was on a roll! But darn that pesky reporter!
When he was exposed, he was completely unconcerned. "These trusting people will stand behind me. A good liar is a good judge of people," he said. Amazingly, he was right. Far from being outraged at the fact that they had all been completely deceived and lied to from top to bottom, the local community he had conned so completely to accrue benefits and honors to himself that he had not earned, rushed to his support!
What kind of psychological weaknesses drive people to prefer lies over truth?
This may have something to do with what is called Cognitive Dissonance. Leon Festinger developed the theory of Cognitive Dissonance in the 50's when he apparently stumbled onto a UFO cult in the Midwest. They were prophesying a coming world cataclysm and "alien rapture." When no one was raptured and no cataclysm he studied the believers response, and detailed it in his book "When Prophecy Fails." Festinger observed:
A man with a conviction is a hard man to change. Tell him you disagree and he turns away. Show him facts or figures and he questions your sources. Appeal to logic and he fails to see your point.
We have all experienced the futility of trying to change a strong conviction, especially if the convinced person has some investment in his belief. We are familiar with the variety of ingenious defenses with which people protect their convictions, managing to keep them unscathed through the most devastating attacks.
But man's resourcefulness goes beyond simply protecting a belief. Suppose an individual believes something with his whole heart; suppose further that he has a commitment to this belief, that he has taken irrevocable actions because of it; finally, suppose that he is presented with evidence, unequivocal and undeniable evidence, that his belief is wrong: what will happen? The individual will frequently emerge, not only unshaken, but even more convinced of the truth of his beliefs than ever before. Indeed, he may even show a new fervor about convincing and converting other people to his view.
It seems that part of the problem has to do with ego and the need to be "right." People with a high "need to be right" or "perfect" seem to be unable to acknowledge that they have been conned. "There is no crime in the cynical American calendar more humiliating than to be a sucker." People will go along with and support a psychopath, in the face of evidence that they have and ARE being conned, because their own ego structure depends on being right, and to admit an error of judgment would destroy their carefully constructed image of themselves.
Even more amazing is the fact that when psychopaths do get exposed by someone who is not afraid to admit that they have been conned, the psychopath is a master at painting their victims as the "real culprits."
