The theory of emotion, through much of the twentieth century, was dominated by the idea that emotion is learned through the culture you grow up in. But a man by the name of Paul Ekman, thought this thinking was faulty. He believed Darwin's theory of emotion was correct, which supports the idea that there are basic emotions that are a product of our biology. In other words, they’re universal, something we all have in common. So Ekman and his colleagues set out to test this idea in 1967 and, after traveling across the globe to run cross cultural experiments, they found support for six emotions that we all share: happiness, sadness, fear, anger, disgust, and surprise. But today the study of emotion is a burgeoning field. It’s believed that all of our decisions and actions are spurred by emotion, so researchers are studying other emotions—ones that go beyond our basic need to survive and look at how we thrive. We talk with Jessica Tracy, a researcher and professor of psychology at the University of British Columbia, about her new book, Pride.
