not necessarily. most people I have encountered lie because...

its a learned behavior. children are taught to use their imaginations, play pretend and other games that include elements of hiding, having secrets,. even adults do it.. last month I went to a surprise party where we had to lie to the birthday person to get her to the location with out her knowing the true reason behind having to go there.

whats the most common element in an abusive situation …(child abuse, domestic violence, terrorism.....) the abusers code of conduct of "do not tell or else...." so again a person is in a situation where the childhood taught element of telling lies comes into it where the victim must use their imaginations and come up with a believe able story for the bruising and so forth and unwelcome questions about their life.

Whats the most common element in elementary, jr high and high school when a student doesn't want to do their homework or go to school....using their imaginations like they have in toddlerhood, preschool and kindergarten and so on... to come up with stories why their homework wasn't done or that they were sick and couldn't come to school.

in adult hood whats the most common thing that happens when someone doesn't want to go to work. do they call in and say "hi boss I just don't feel like coming in today, so Im staying home and watching Netflix and sit on facebook all day." no they use their imaginations like they have been taught to do in early childhood, call their boss and say "I have a sore throat.. I have a doctors appointment, I cant come in I have the flu..."

in fact its so normal and built into human existance to lie that even early documents on humans and animal kingdoms shows how early humans and animals naturally used the element of using ones imagination and lying for safety, fun and the preservation of the species.

though a very few that I know have used their natural brain activity and learned behavior of lying for crimes and so forth I find most that I encounter are doing so because that's just how they have been taught to do things.

if you are having a problem with telling lies heres what worked for someone else that I know... each time they told a lie they stopped their self, admitted they were lying (admitted either to their self or the one that they were lying to) wrote it down and then listed appropriate behaviors that they could do or say next time they are in the same situation.
