Are you a pathological liar well... it is said that three lies are said to be told in a 10 minute conversation with a stranger, if thats you then you a pathological liar if not than lets try and understand a pathological liar. The first step is ....Why do people lie? That’s simple humans are social animals meaning they would say anything for social interaction? In other words if you have friends you don’t want to really lose them or shall be lonely forever. Lying is actually difficult on the brain, I that sounds strange but it is true. Scientist even say that lying could start as early as 6 months old like fake crying etc..., they also say that once the kid gets older its one out of every five interactions are filled with lies, by the time you an adult lies have become ingrown and well people who lie manage to keep numerous thoughts in their heads. These people are what scientist call a pathological liar .The scary part is that the lies become so much that people start believing their own lies. Pathological liars and the average man brain varies; Gray matter which is the back part of the brain( Function- processes) has the most research done on it where the White matter has no as much makes up most of our brain (carries electrical signals from neurons to another).Research showed that pathological liars have 25% more white matter in their prefrontal cortex than normal people. They can keep all this information to sustain their lie and believe their lie. They also have 14% less gray matter. Pathological liars have a problem keeping a job or a relationship because eventually people begin to realise that they are compulsive liars.
