I don't know if something like that has been posted before: Traits of a psychopath.
Does it sound like anyone we know?
1. Emotional manipulator
Playing on sympathy is a favourite weapon of choice for psychopaths. While they are confident, outgoing and mentally resilient and rarely feel sorry for themselves, they are master manipulators are extremely proficient at eliciting pity and compassion.
2. Control freak
If you feel like you are being micro-managed, you probably are!
3. Charming
Psychopaths are past masters at making brilliant first impressions and charming your socks off.
4. Bloodsucker
Psychopaths are corporate vampires who take you into their confidence only to suck out all the valuable new ideas that may have been weeks and months in the planning. Before you know it, your idea has become theirs” and they are getting the credit for it.
5. Liar Liar
A tendency to misrepresent the facts while appearing plausible and reasonable, along with a lack of guilt or anxiety over telling lies is another hallmark of psychopathic behaviour. But they are hard to spot because the lies often contain just enough truth that a spurious cover story can be concocted if they are scrutinised too closely.
6. Narcissistic
Though they may pretend concern for others, appearing warm, considerate and even helpful, make no mistake, psychopaths are completely self-interested, often coupled with an arrogant, grandiose and egocentric interpersonal style. “Friendships” are often terminated without warning once you cease to be “useful”. If your boss thinks he/she is more skilled, important or valuable than anyone else, or has a habit of stealing the limelight from others, then you may wish to consider moving on.
7. Teflon-coated
Psychopaths never accept responsibility for their mistakes and poor behaviour. Worse than that, they are brilliant at manufacturing evidence that makes someone else look guilty so the blame is quickly shifted. Psychopathic bosses have no shame when it comes to using employees as expendable buffers to ensure their own standing and reputation is not sullied if performance is being questioned.
8. Great acting skills
The part of our brain responsible for emotion is turned down (or even off) in a psychopath, meaning he or she doesn’t experience normal feelings like the rest of us. Feelings like fear, regret, disgust, and shame aren’t familiar to them. But psychopaths are brilliant actors who will act scared, sorry or surprised in order to manipulate others if it will help them advance their own agenda.
9. Risk taker
Things that would scare the hell out of a normal person don’t frighten a psychopath at all. In fact their unemotional composure under fire is part of their attractiveness and explains why they often achieve success in highly volatile professions. But this lack of fear and warped view of risk can also lead to unnecessary risk-taking.
10. Power-hungry
Psychopaths need to control and manipulate others and so are attracted to positions where they can influence others. Any organisation that has a hierarchical structure which enables an individual to have a position of power over others is attractive to people with psychopathic tendencies – even better if they get to wield their power with impunity.
