Introverts are more honest than extroverts?

In one of the newer TED talks (click for video), a speaker named Pamela Meyer made an interesting claim that extroverts are more likely to lie than introverts. The problem with her lecture was that she provided no explanation for why. I agree with her, and I believe the reason extroverts are more likely to lie is because they exchange information for the sake of pleasure (they communicate in a way that maximizes pleasure). On the other hand, an introvert tend to exchange information for the sake of its accuracy and usefulness (which is why introverts are more honest, they value the information, not the feelings associated with communication). Introverts tend to dislike small-talk, which consumes the vast majority of extroverts communication. Extroverts could mindlessly babble on about anything all day long (nothing wrong with that, I suppose). And being that the primary objective of an extrovert in communication is to "feel good" they will bend the truth to accommodate this goal.

In short, it tends to be that introverts value accuracy of information, extroverts value the way information makes them feel. Obviously there is a spectrum here, most people find themselves somewhere around the middle. I find myself leaning towards the introvert side more than most people, but I do engage in some small-talk once in a while (albeit often awkwardly).
