The word ‘psychopath’ makes people think of individuals like Eric Harris, Dylan Klebold and Elliot Rodger. However, it is estimated that between 1 and 4 percent of the world’s population is made up of psychopaths and lucky for you, they probably aren’t all murderous.

Psychopathy is a deeply complex psychological condition which many are living with every day. While the term understandably has something of a stigma attached to it, not all psychopaths are likely to hurt people. There are many characteristics of a psychopath but they often lean towards exhibiting boredom, pathological lying an impulsiveness.

The complete 20-point PCL-R checklist for psychopathy is as follows:

– Glibness/superficial charm
– Grandiose sense of self-worth
– Pathological lying
– Cunning/manipulative
– Lack of remorse or guilt
– Emotionally shallow
– Callous/lack of empathy
– Failure to accept responsibility for own actions
– Need for stimulation/proneness to boredom
– Parasitic lifestyle
– Lack of realistic, long-term goals
– Impulsivity
– Irresponsibility
– Poor behavioural controls
– Early behavioural problems
– Juvenile delinquency
– Revocation of conditional release
– Criminal versatility
– Many short-term marital relationships
– Promiscuous sexual behaviour

There are often other clues that someone may be psychopathic. Xanthe Mallet, a forensic anthropologist and criminologist at the University of New England, believes that the telltale signs lie in the way someone speaks and whether their physical and verbal cues match up.

Some psychopaths will go on to do terrible things. However, they are in the minority. As is the case with any decision, in the decision of whether to take another’s life there will be many factors involved including nurture as well as nature. But perhaps you’re not quite a psychopath. However, if you take a lot of selfies in the gym it may be another psychological condition you have.
