The brain is a complicated piece of machinery scientists still full don’t understand. Each lobe of the brain serves a different function and within those lobes are sub-functions, but many researchers argue that certain types of people can be divided into halves of the brain.

According to the theory of left-brain or right-brain dominance, each side of the brain controls different types of thinking. Additionally, people are said to prefer one type of thinking over the other. For example, a person who is “left-brained” is often said to be more logical, analytical, and objective, while a person who is “right-brained” is said to be more intuitive, thoughtful, and subjective.
