There Are Actually Two Kinds of Extroverts — Which One Are You?
You probably know the differences between introverts and extroverts, but did you know that it can go a level further?
According to a study published in Cognitive, Affective, & Behavioral Neuroscience, there's is quite possibly two different types of extroverts!
"Many studies have found that there are two domains of extraversion based on self reports," Tara White, study co-author and professor at Brown University.
1. The Go-Getter
These extroverts are more assertive, persistent and achievement-driven, the kind of person always raising their hand in class - think Hermione Granger.
2. The People Person
These extroverts are friendly, emotionally warm and great with ice breakers.
But how did they even come up with this tiny difference? The researchers examined nearly 100 brain scans from people with a range of personality traits, not all of whom were extroverted. The team then compared the scans of those on the self-claimed go-getters with those on the self-claimed people people and found one big difference. It's all a gray matter.
The more gray matter you have in your brain, the better that region will work to keep your senses sharp. People who scored as go-getters had greater gray matter in specific regions of the brain than people persons (and vice versa)
The researchers still don't know the answer to whether personality traits are assigned at birth, if certain factors spur the brain to develop this way or if it's a combination of both.
Either way, this study proves that while many of us are extroverts, that doesn't mean we're all the same.
