I've read a few things about the predominate parts of the brain introverts and self-discipline employ.

The PET scans revealed that introverts have more activity in the frontal lobes of the brain and anterior, or front, thalamus. These areas are activated when a person's brain takes on internal processing such as remembering, problem solving and planning. Extroverts exhibit more activity in the anterior cingulate gyrus, temporal lobes and posterior thalamus. These areas are typically thought to be more involved in sensory processing such as listening, watching or driving.

To sum up: both will power and discipline are learned, which means neuroadaptations, primarily in the pre-frontal cortex, account for these behaviors

So there's the armchair diagnosis. Introversion and will power due to higher use of the frontal area due to the wiring (either hardwired or through 'training').

Anyone hear of such a thing or have any insight into this possibility? What about extroverts and willpower?

Injury to the prefrontal cortex can affect your most human qualities: the ability to process information and solve problems; to concentrate, remember, and learn. Damage here can lead to personality changes that manifest in impulsive and socially inappropriate behavior, depression, and violence.

Okay, so you are making the connection between willpower and introversion because both seem to be characterized by higher activity in the frontal lobes of the brain. The fact that the prefrontal cortex is active in problem solving and planning does suggest that it would be more involved with long term effects rather than short term, and this is essential for willpower because willpower works off of long term considerations. Yeah that's likely true then that introverts are naturally predisposed to develop discipline and willpower. If that region is most active, then conditioning processes would occur much more rapidly there, as thats how neuronal restructuring changes happen fastest. If that region is inactive, then neuronal restructuring happens slower.

My experience definitely supports this, extroverts definitely seem to have much less work ethic and much more short term based than us introverts, or INTJs at least. I focus on the long term quite a bit, although I make sure that doesn't get in the way of my present.

I agree with the first paragraph, but the comment about work ethic????? What do you mean by work ethic?

By work ethic I mean having the willpower and discipline needed to do work. If you don't have these qualities, you will just quickly give up doing some hard work.

yep willpower... compared to most people i know, i'm the pushy-est and i shock a lot of people whenever i achieve what they think is "the impossible". whenever i do certain tasks, this is my mantra:

"you're the most beautiful goddess in the cosmic realm"

This is interesting. I certainly possess a huge amount of willpower ONCE I am convinced of something. Before I am convinced, by feelings or arguments or whatever is important, i can sway to whatever happens. But when something interests me, and I believe in something, I usually push it as far as possible. Due to this Im usually good at whatever I take interest in, and I am also prone to overtraining -.-

My input on the discussion on introversion vs. extroversion in amount of willpower... well, as far as I know, from my education that is, this could very well be true. I dont know from experience if there is some hardcore correlation between introversion and self-dicipline though, but it seems reasonable. But back to my academic point; our cortex, specifically frontal cortex, is what makes us human and makes human stand out from animals. That this area is more highly activated for introverts makes total sense. If we are thinkers, of course our brain is thinking. But the frontal cortex is more than higher cognitive functioning such as abstract insight and theoretical analyzing. It's also a part of something else that makes us different from the animals - our ability to control ourselves. That is, limit emotions, regulate moods, control behavior or thoughts and preventing "automatic" functioning on instincts, routines, whatever. So, it seems to me that the connection between introversion and "willpower" may very well exist.

Just my 5 swedish öre's, as an academic

If the functions of the prefrontal cortex are what mainly distinguish humans from animals, and introverts have more activity in the prefrontal cortex, may that imply that introverts are "more human" in essence than extroverts, by having more control over our "lower" functions (in the evolutionary sense)?

You are correct. I do have this elitistic tendency to look down on people who act more on instinct, or automation in any kind... But Ive never thought about the connection with introversion and extroversion before, though. But it seems like a very valid connection to me.

Man INTJs are the best. If only there weren't so few of us...

On the other hand, perhaps there being fewer of us is for the better. There needs to be a certain balance of personalities for society to flourish, and maybe its just better to have fewer "masterminds". Haha, imagine a society with only INTJs! It just would not work lol!

Wow, that's pretty good,

INTJs in general are able to set long range goals
and defer gratification; you have to admit that takes some will power.

Some people work hard because they have conviction to do so,
other people, when they feel they can get away with it, become lazy
and do as little as possible.

Good things about being few is there are less "social traps" (like advertising) geared toward us since they would be difficult to prepare (we are quite good at avoiding restrictions to our freedom) and would grab too few people. Other good thing is that common joes don't know how to deal with us so they let us be.
