Right brain versus left brain
I took the test and found it to be extremely accurate. I’m more of a 60(left brain)/40 (right brain) guy, quite balanced. My score is 38/100; anything below 30 is more left while anything above 70 is more right.
Here’s the analysis of my score:
In your head, it’s the left hemisphere that rules the right to run your life. Your world runs like clockwork - perfectly organized and systematic, with everything done on time. A messy room or misplaced paperwork? Not in your left-sided world! You’re likely a conscientious and meticulous individual who is almost always well-prepared for everything and anything.
Complex problems or difficult decisions are handled with ease and expertise: you break things down, analyze them step by step, and come to a well-informed and thought-out conclusion. You are extremely comfortable expressing yourself verbally, and likely prefer taking a theoretical rather than practical approach to understanding the world around you. Being ruled by emotion or impulses is not in your nature - no matter what you do, it’s always “think first, act later”. Although this may indicate that you’re not much of a risk-taker extraordinaire, it does imply that you can be trusted to always have a “Plan B” and to be ready for whatever obstacles come your way.
While some people may have difficulty making sense of this fast-paced, topsy-turvy world, your logical and rational nature helps you put everything into perspective. Life’s “big picture” is important, but it’s the little things that matter most to you. No matter how complex your life gets, you always manage to figure things out and set them right again.
