Bottom line: lying generally requires greater effort by the prefrontal cortex* than telling the truth does. This actually makes it stimulating and even more fun for the narcissist.
Anyone who’s been involved with a narcissist knows that they often have a somewhat casual relationship with the truth. Many (if not most) lie with impunity, and often so convincingly that our own sense of reality can feel like we’re standing on shifting sands. What is, in fact, real from what they are telling us?
There are many reasons that narcissists lie. To manipulate, to gaslight, to control, to avoid responsibility, to get attention, etc. (See this post for more on the narcissist and lying.) But one we often don’t consider is that it is fun for them.
In my own case, I have to confess I believed everything he told me. Why wouldn’t I? He was my partner, my soul-mate. Now, of course I know that people lie. In fact, research shows that human beings tend to cook up stories a couple of times a day. But serious deception in a personal relationship was simply not what I was counting on.
At some point after I left and was deep in my healing process, I found myself pondering something he had told me and realizing in that moment, that it was probably a lie. Not to be too cliched here, but it was like the sun coming out from behind the clouds. All of a sudden I could see. Why was I taking what he had said as true? Wasn’t it much more likely that a large percentage of it were lies?
But why did he lie to me? For all the reasons above and — because it was more fun. Narcissists appear to have a disrupted relationship to the neurotransmitter dopamine, which cues us to what is rewarding and worth our attention. More research need to be done in this area, but the cues point to that they tend to be constantly seeking dopamine-inducing experiences. This may explain why there is so much “co-morbidity” for narcissists — that is, other issues such as addiction. They need more and/or more constant dopamine than non-narcissists in order to feel stimulated and alive.
Lying requires greater effort by the prefrontal cortex (PFC) than telling the truth, and things that add stimulation to our PFCs generate neurotransmitters such as dopamine and norepinephrine (adrenaline). By the way, this is true for both narcissists and non-narcissists, and is why, for most of us lying feels stressful and we don’t really tend to enjoy it. But for a personality type that is low on dopamine, a nice juicy lie can spice things up and make life more interesting.
Ah yes, the more you know……
