Every person is unique. We all think in very different ways, learn in diverse styles, and view the world as vastly different. However, even with no two brains being alike, science can still make inferences about us based on generalizations from our thoughts.
Patterns have been studied that "predict" which side of our brain is more dominant over the other. Now I have predicted in quotations because like all theories, they have not been proven, but rather studied. It's fairly difficult to truly determine what makes us who we are exactly. With that being said, it's still fun to see which side of the brain matches us best.
There are two sides that correlate to our traits. A right-sided brain person is very contrasting to that of a left brained person. It's said that a right-side dominate person is intuitive, creative, free-thinking, and spontaneous. They are more inclined to artistic tasks and in-tune to the feelings of others. While often daydreaming, they still see the bigger picture of things rather than the minuscule details. On the other side, there is a left brain dominated personality. They are attracted to the analysis of details and logical deductions. Areas within the sciences are often their strong suits that hold their interest the most. Verbal and written language comes easier to them, hence why if you're left brained you might remember names over faces. They thrive most off of structure and organization which lead them to avoid things like unplanned spontaneity. These are generalizations of personality traits, not proven laws of the brain.
Since we aren't completely made up of just one side of our brains some aspects leak from the individual sides. We use both hemispheres of our brains but usually, one side seems to dominate over the other. It wasn't until I had taken a few of these quizzes that I started to notice something a little different. I would take one and get 60% left brain and 40% right brain. I would take another quiz but get 40% left and 60% right. Other times I would continually get 50/50. As I read through the results description, it described how I am neither a more dominant left or a dominate right but instead split-brained!
In other words, I use both my left side of my brain almost as equal to my right side. After taking quite a few, I really have to agree. Over the years I've discovered and accepted that I'm just a messy mix of both, full of personality traits that contradict each other. I'm a chemistry major that loves painting, doing art, and writing. I crave structure, so much so every morning I create a to-do list and I double check that my agenda is filled in every hour of the day with that I'm going to be doing yet if I don't complete it all it doesn't bother me. I love spontaneous trips and being surprised just as much as I love knowing exactly what time I'll be eating lunch that day. The clothes in my closet are organized by shirt style and color but often times those clothes end up scattered on my floor. My intuition about people and their feelings are rarely ever wrong but I still rely on facts and truths. Center-brained people are sometimes called the jack of all trades since a little bit of everything comes naturally to them and holds their interest.
While being a twist of both has helped in so many ways and is just who I am, there are some downsides. Since I love a little bit everything I find that it's hard for me to really focus on one thing to be amazing at. In my science courses, I'm not over excelling but I'm doing pretty well. I love painting but I doubt anyone but me will ever see my work. Having an equal amount of the sides contributing to my personality makes it as though I'm just adequate in all the areas, never mastering them fully. Nevertheless, I would never want to be anything less than my homogeneous mixture of traits. It makes up so many of my favorite aspects of myself.
Here, Here, and Here you can take a few tests to see where you stand. Being left-sided is no better or worse than being right-sided, which is no better or worse than being a little mix of both. Whichever you discover you are, embrace it and see where your strengths lie.
