Mind: Introverted vs. Extraverted

It is safe to say that Extraversion and Introversion are probably the oldest notions in the history of personality theories. It has long been observed that some people are expressive, outgoing and comfortable in interacting with their surroundings – while others are reserved, quiet and more comfortable alone. It is as if the former sincerely enjoy engaging with the external world and recharge by communicating with other people, and the latter prefer to rely on themselves and their own inner world instead of seeking stimulation from the outside. We focus on these differences in our first scale, which we call Mind – it determines how we see and approach the outside world, including people, objects and activities within it.

While Introversion and Extraversion are often used in lieu of social aptitude, this scale involves more than just being outgoing and social – although social skills form part of it. In a broader way, the Mind scale determines the degree of interaction with the outer world; how socially one behaves is just a part of that. In a sense, this scale is a contrast of the quantity and intensity of an experience and its quality or depth.

People who are considered Extraverts (E) in our model are not as sensitive to outer stimuli and need to seek them out in order to gain a kind of functional equilibrium and to perform well. Introverts (I), on the other hand, are more sensitive and need to escape the same stimuli in order to be more functional. Unlike Extraverts, Introverts can quickly exhaust their mental energy reserves, and they will only tolerate such situations so long before they yearn for solitude and quiet.

Let’s consider a couple of practical examples. Our research shows that Introverts are significantly more likely to report being sensitive to noise and bright colors, and they also strongly prefer simplicity and minimalism in their environment (especially if their Introversion is coupled with the Thinking trait). Likewise, they do not seek or require much external stimulation – while communicating with other people is the most obvious example of such stimulation, this concept also extends to things like hobbies, political attitudes and even eating or drinking habits. For instance, Introverts are more likely to dislike coffee and energy drinks.

On the opposite side of the spectrum, Extraverts are more interested in engaging the environment – people and objects around them – and they need feedback as well. They are more energetic and willing to take the lead in many situations, especially social ones, and they enjoy pushing limits and challenging both themselves and those around them. People with Extraverted personality types are also more likely to feel that they can handle any challenges life throws their way. Obviously, whether that turns out to be true or not depends on many other circumstances, but generally speaking, Extraverts tend to be much more proactive in experiencing (and relying on) the world around them.

Finally, it is important to point out that the Mind scale does not determine how introspective or reflective we are – even though it may be tempting to confuse the two. There are introspective Extraverts and non-introspective Introverts. Ultimately, this scale is about how much stimulation we require and can absorb from our environment, not about what happens in our minds afterwards.

I’m a highly sensitive introvert, emotionally and physically. Noises and bright lights seem to bother me the most, and my ears tend to pick up everything, no matter how insignificant the noise. I’m very sensitive to touch and I often feel someone is watching me from behind, even if they just left.

Mostly extrovert. Love to write and perform (campaigner). More than anything though, I love what I call "the white heat," the process by which inspiration enters me. When it happens, my goal is to create art to share w the world.

So cool! I'm 68% introvert. I think it's cool though I'm a logistician. I'm generally more of a thinking type, who is shy and reserved though often (no bragging) I have spikes of having a bright mind. This is usually when I'm alone at in the evening. From walking back from school and staying home alone, really helps clear my mind and I think it's a healthy way to get rid of stress.

Extravert here (51%). Love coffee but it doesn't keep me awake, either. I don't know why it works for everyone else. Maybe there's different degrees of sesitivity to caffeine? Soda does it for me, though, specially Coke. Now I'm wondering if Coke maybe has more caffeine than coffee itself... Possibly.

This is interesting, because I'm an extravert that hates coffee. I don't know how well it keeps me awake because I haven't observed the effects enough times, I just really don't like the taste.
