The Intricate Dance of Personality: Is it a Left or Right Brain Affair?

Personality consists of enduring patterns of thoughts, feelings, and actions. These traits are shaped by a combination of life experiences and an intrinsic core facet that is hardwired within us. This core is often influenced by whether we are left-brained, favoring logical and structured thinking, or right-brained, leaning towards creativity and exploration. The concept underscores the role of brain dominance in shaping our inherent personality traits.


The age old debate surrounding personality and its roots has often pivoted on nurture vs. nature. However, with the advancement of neuropsychiatry, our understanding has taken an intriguing shift. Is our inherent personality linked with the dominance of a particular hemisphere of our brain? This question sets the tone for a fascinating exploration into the recesses of our mind and its influences on the usual patterns of our thinking, feeling, and behaving.

1. Personality Defined:  

Personality, in its most distilled form, can be seen as the habitual patterns of thinking, feeling, and behaving that characterize an individual. This longterm consistency in our reactions, choices, and emotions is what distinguishes us from one another, making each person unique.

2. External Influences on Personality:  

Life’s myriad experiences play an undeniable role in shaping our personality. From childhood events to interactions with role models at different life stages, these external factors mold our worldview, our reactions, and our aspirations. The continuous interplay between our inherent traits and life’s lessons subtly refines our personality over time.

3. The Instinctive Core of Personality:  

Despite the undeniable influence of life experiences, there lies within each of us a core, an instinctive element that remains relatively steadfast. This core, much like the foundational layer of a painting, provides the backdrop against which all other colors and strokes emerge. It’s a deep rooted, hardwired aspect that gives us our natural tendencies and inclinations. And this instinctive core, as research suggests, may well be influenced by our brain’s hemispheric dominance.

4. Brain Dominance and Inherent Personality Traits:  

Drawing from a personal anecdote, the distinct behaviors of two dogs, a German Shepherd and a Basset Hound, can serve as an analogy. The German Shepherd’s purposeful approach, marked by a focused, uninterrupted walking pattern, mirrors the analytical, goal oriented thinking associated with left brain dominance. In contrast, the Basset Hound, with its explorative and sensory driven nature, resonates with the holistic, in the moment thinking of the right brain. Such distinct behaviors, rooted in inherent tendencies, underscore the influence of brain dominance on our natural inclinations.

5. Embracing the Dance of Nature and Nurture:  

As we navigate life, it’s essential to recognize the symphony between our hardwired inclinations and our acquired experiences. While our brain’s dominance might give us an inherent rhythm, life’s lessons finetune the melody, resulting in the unique composition that is our personality.


Personality, with its intricate layers and nuances, is a dance between the natural and the nurtured. The hemispheres of our brain play a silent yet powerful role, providing the foundational beats to which life’s experiences add the melody. Recognizing and embracing this interplay can help us understand ourselves better, offering insights into why we think, feel, and act the way we do.

“In the theater of personality, our brain sets the stage, and life writes the script.”

Explanation of the Quote:  

The quote beautifully encapsulates the essence of the article, highlighting the foundational role our brain (specifically its dominance) plays in shaping our inherent personality. Yet, it’s life’s experiences, lessons, and interactions that add depth, flavor, and nuance, much like a scriptwriter adding dialogue, emotion, and plot twists to a theater’s set stage.
