Tonight I was reading several PhD psychiatrists/psychologists who were describing Narcissistic Personality Disorder and BO. The several opinions I've read so far all say that, although they haven't professionally evaluated BO, they can tell a lot from his upbringing and childhood, behavior patterns, bragging, emotion-free language, his associations, his body language (haughty, superior), craving power, his comments, etc. They describe the definition of NPD and he fits it to a T.
The scary thing is they say that people who have NPD are very charming and deceptive. "When the narcissist reveals his true colors, it is usually far too late. His victims are unable to separate from him. They are frustrated by this acquired helplessness and angry at themselves for having failed to see through the narcissist early on."
"There have been a lot of studies that have found narcissistic leaders tend to have volatile and risky decision making performance and can be ineffective and potentially destructive leaders."
One PhD gave a bunch of specific behaviors BO has done that fit NPD. SCARY.
Edit: OK, I can't stand it, I have to tell you some of the abbreviated list of NPD behaviors he's shown:
1. Subtly misinterprets facts and expediently and opportunistically shifts positions, views, opinions and Ideals.
2. Ignores data that conflict with his fantasy world or with his inflated and grandiose self-image. (magical thinking) Additionally, he denies the gap between his fantasies and his modest or limited real-life achievements.
3. Feels that he is above the law, including and especially his own laws.
4. Talks about himself in the 3rd person singular or uses the regal "we" and craves to be the exclusive center of attention, event adulation.
5. Has a messianic-cosmic vision of himself and his life and his "mission."
6. Sets ever more complex rules in a convoluted world of grandiose fantasies with its own language (jargon)
7. Displays false modestly and unctuous folksiness but is unable to sustain these behaviors (the persona or mask) for long. It slips and the true Obama is revealed: haughty, aloof, distant, and disdainful of simple folk and their lives.
8. Sublimates aggression and holds grudges.
9. Behaves as an eternal adolescent (choice of language, youthful image, demands indulgence, feels entitled to special treatment even though his objective accomplishments do not justify it.)
This is only a short bit of the whole article, but you get the idea. It's by Sam Vaknin, PhD, who has studied NPD for 12 years, is an expert on narcissism and has written a book called "Malignant Self Love"
