The two sides of the human brain have distinct abilities unique to either the right side or left side. An individual's strengths and weaknesses are often based on which side of the brain is dominant. It's always been presented to me as left-brained being the logical, methodical, and pragmatic side and right-brained is the creative side. There have been books written on this phenomenon.
At least that's the way I've always understood left vs. right brain.
The first thought is that writers must be right-brained since writing is a creative effort. And many writers are also involved in other creative endeavors such as various forms of art and music. But it seems to me that's only partly true.
As a writer, I certainly deal with my right brain creative side. But as a writer, I also need my left brain methodical, logical, pragmatic side as part of my creative effort. I would consider doing research as being methodical left-brained. And then there's the switch over from right brain creative to left brain logical when writers go into edit mode. And that edit mode is necessary in order to take a creative effort and hone it into a marketable effort. And the many facets of self-promotion for our books is certainly methodical and logical.
I recently came across a ten question quiz to test whether someone is a right brain thinker or a left brain thinker. Not sure I agree with all the conclusions, but I found it interesting.
