Are people either “right-brained” or “left-brained"?

FALSE 

Regardless of personality or skill set, you use both the right and left hemispheres of your brain to perform everyday tasks. Although certain functions, such as speech production, handedness, and facial recognition, tend to be dominated by one side of the brain in the great majority of people, most tasks require parallel input from both hemispheres. The integration of input is made possible by the fiber connections between right and left sides of the brain called the corpus callosum. Unless an entire hemisphere is completely removed or damaged, no one is considered to be fully “right”- or “left”-brained.
