Psychologists have always assumed that the way emotions are organized in the brain is the same for all of us. But now, a new study suggests that left-handers process emotion in the opposite side of the brain to right-handers—which could change the way we think about and treat mental disorders.
Left-handers aren't very common. In fact , they only represent about 10 percent of the human population. But a new study suggests that the reason lefties are in the minority isn't anything suspect—rather, it boils down to the fact that the human race cooperate more than they compete.
