My 11 year old son is a compulsive liar. It does not appear conscious; he lies about anything at all, even things he wouldn't get in trouble for. He doesn't think at all about what he says.
I'm struggling with several lines of thought and personal experiences:
(1) As a child, I was accused of lying even when I was telling the truth. I was not a habitual liar but I couldn't convince my parents that I wasn't lying. So I was punished even when I wasn't lying and was telling the truth. My conclusion: A child needs to be led to tell the truth without fear of consequences.
(2) When I was a child, my lying intensified when I knew that I would be punished for the truth. My conclusion: Punishment for lying will cause a child to lie more.
(3) A child needs to be punished to stop the lying behavior.
So here is an example of what I currently do:
Did you brush your teeth?
Yes
Ok, let me see how you did.
It doesn't look like they were brushed.
But I did!
(Gives the "Mom" raised eyebrows look.) I need you to tell me the truth. DID YOU BRUSH YOUR TEETH?
No.
Go brush them. (This is a consequence of lying, but not really a punishment.)
Sometimes I will add a lecture about how bad lying is.
This sounds very stupid, I realize, and I'm embarrassed about that, but I just remember how my childhood experiences enhanced my lying. If I were to pile on severe consequences, I feel like the lying would leap tenfold, with lies to cover lies.
So where is the effective middle ground? How do I punish lying behavior without making it worse? At this point I can still get the truth out of my son about two or three lies down the road. But the bottom line is, he is a habitual liar who lies without giving it a second thought, and if I don't fix this, he is not going to have a good life.
I hope someone here can help.
