Oranges are lefties. The fragrance of an orange comes from limonene, the same chemical that gives lemons their distinctive odor. However the molecular structure of an orange’s limonene is the mirror image of "right-handed" limonene in lemons. All of nature, from spinning electrons to spiraling galaxies, seems organized by left- and right-handed preferences.
Biasing entities toward the right or left is Nature's way of avoiding symmetry, indeed, of avoiding perfection. Natural diamonds are more scintillating than human-made diamonds because the latter are structurally perfect.
Perfection leaves no room for progress, thus inhibits evolution. Perfection, in fact, can lead to aberrant outcomes. For instance, manufactured drugs usually have an equal number of left and right biased molecules, giving them structural perfection. However, drug makers have learned to reduce side effects by endowing drugs with a molecular architecture that is biased to the right or left. It was thalidomide’s molecular perfection that caused the tragic birth defects associated with the drug.
Before Roger Sperry and Joseph Bogen’s Nobel Prize winning research that revealed functional specialization in each of the brain's hemispheres, many regarded the right hemisphere as largely redundant tissue. It was called "the minor brain. Now, of course, we know differently. The "right brain" is critical to our making sense of reality and many regard it as the soul of creativity.
Knowing something about how brains and the energized aura called the mind work leads to better marketing. After all, marketing is about getting information into people's brains and influencing their minds to take some action. Marketing messages with a right brain (emotional) bias often work better than marketing messages with left brain (rational) bias.
