For a while now, humans have conveniently classified themselves as either being left-brained or right-brained. The popular notion behind this was/is that people in tune with their left brains are analytical, while those with the right brain are creative. Left brainers think logically, objectively, are usually good with numbers, and generally academically proficient. Right brainers, on the other hand, are incredibly imaginative, they are daydreamers, love music, arts, and, so on. From this, various issues have sprung up.

The classrooms favour the left brainers and so it is unfavourable for right brainers. Also, the creative minds are the ones that move the world, not the smart bookish nerds. The drama has been on since forever; however, most of this is just mere…talk. This concept of thinking was developed from the research in the late 1960s of an American Neuropsychologist Roger W Sperry. After conducting a few researches for patients with epilepsy, he grouped the functions of the brain as left or right. The left hemisphere is responsible for language, mathematical computations, logical work, and so on. The right hemisphere, is for facial recognition, music, processing images, etc. hence, if a part of your left brain is cut, you would probably never be able to work mathematics or understand language – at all.

Clearly, the left brain/right brain theory of personality is widespread, but it is not exactly science, or real. In fact, it is almost comical like another successful marvel animation. You can call it pseudoscience, or just an exaggerated scientific idea. Yes, the brain is divided into two parts – known as hemispheres – left and right. The left hemisphere being responsible for controlling the right part of your body, and the right hemisphere responsible for controlling the left part of your body. That’s pretty much how far science can succinctly go. Further research has, of course, gone on to counter Sperry’s claim(s).

We have been made to understand that the brain is not as dichotomous as we believed; we’ve learnt that both sides of the brain need to work together for certain functions, and researchers have debunked the myth by identifying specific networks in both the left and right brain that process lateralised functions. In essence, there is really nothing like a person having a much dominant part of the brain than the other.

Both sides of the brain work just as much from person to person. There are really no two people – left and right personalities, in our brains that we have to choose. Asides all this scientific discoveries that have come to prove that all of this is a joke, a whole lot of flaws were already apparent. The first is that most of these are dependent on the other. Being creative as a writer is great, but if you had bad language skills, most of your creativity would not be materialised, and vice versa. More so, in today’s world – and even much older periods, we have found a lot of people with both sides of the brain working at high levels.

We have Leonardo Da Vinci, Picasso, and the millions of people that are soaring today, by simultaneously working with both brains in different areas of their lives – being good at left brain roles and right brain roles. Besides, trying to explain which of the sides is the ‘winner’ of the personality success battle thingy, is almost too absurd to be real. A person can be as successful as a banker or as a painter. Preference plays the major role as well. If I prefer to use most of my mathematical classroom knowledge in my daily dealings, I will. In the same realm, I can choose to let my mind and heart do most of the work for me. Still not forgetting the fact that we need a little bit of both to actually make something out of anything we do.

My theory, humans are as logical or creative as they choose to be, and should not be classified into certain boxes or brain parts in the name of personality type. Most of us were not ‘born this way’ as we have believed; we chose to be this way – but that’s a story for another psyche gist.
