In The Wizard of Oz, Glinda the Good Witch asks Dorothy”Are you a good witch or a bad witch?” The answer was clear in the 1939 movie.

DeSteno, director of the Social Emotions Lab at Northeastern University in Boston, tells USA TODAY’s Sharon Jayson what they learned from seven years of research on 2,000 people.
