What study is done in pathological liars and their relationships?
I am not aware of any specific studies but I can tell you that
pathological liars suffer from antisocial personality disorder
(also called sociopathy). In relationships, these people are
draining and parasitic and should be avoided at all costs. They are
experts at charming even the smartest and most intuitive people. In
relationships, a sociopath sees a target --someone they can use and
exploit. Sadly everyone is a potential target to a sociopath
because we all have weaknessess and the sociopath is a master at
exploiting a person's weakness for their own personal gain. They
lie, lie, lie! I think many believe their own lies but its hard to
tell because a real sociopath probably won't admit to it. The net
is just brimming with information on this topic. One exceptionally
helpful site is www.lovefraud.com. It explains the disorder as well
as providing legal/personal advice on how to deal with such people.
The site also contains a forum in which victims of sociopaths may
share their personal experiences and offer guidance and support to
one another. Of course the DSM (Diagnostic and Statistical Manual)
is the official source of information for any pathology and should
be consulted for a deeper understanding of the pathological liar
and his/her interactions with others.
