In eastern philosophy, yin and yang stands for the synergistic relationship between two apparently opposing forces. In a similar regard, the human brain also is viewed with a similar sense of duality. The right hemisphere being the YIN, the left hemisphere being the YANG.

According to the left-brain, right-brain dominance theory, popularized in the 1960’s by psycho-biologist and Nobel Prize winner Roger W. Sperry. The right side of the brain is best at emotional and imaginative tasks. The left-side of the brain is better suited for tasks involving reasoning, language, and analytical thinking.

Researchers set out to challenge out this hypothesis, publishing the results of their project in August of 2013. The findings of their research show no evidence to support the notion that people who use the right side of their brain are more creative and subjective, or that people who use the left side of their brain are more logical and objective.

The two sides of the brain are linked together by networks of nerve fibers, creating an information highway of sorts. The two sides do function differently, but they are synergistic, imagine a careful balancing act VS an active and passive relationship. 

Quote: When a person has access to both the intuitive, creative and visual right brain, and the analytical, logical, verbal left brain, then the whole brain is working...And this tool is best suited to the reality of what life is, because life is not just logical-it is also emotional. - Stephen Covey

Whether you’re performing a logical or creative function, you’re collecting input from both hemispheres of your brain. For example, the left brain handles statistical calculations, but right brain aids with comparisons and rough estimates. The left brain is credited with basic language, but the right brain assists you in understanding tone, mood, and context. 

While the idea is most certainly over-hyped, over-sensationalized, over-generalized and overstated, understanding your strengths and weaknesses can help you develop better ways to absorb information and develop new skills.

For example, employers who struggle to find creative ways to inspire their employees (a right-brain characteristic) could benefit from implementing more team building exercises. Entrepreneurs who are extremely innovative and inventive, yet have trouble diving into the analytics and operations of their business, could benefit from taking an online course in accounting and/or finance, building their so-called left brain capabilities.
