The Greater Good Magazine says that “diversity” is an obvious fact of human life — namely, that there are many different kinds of people in the world. And that diversity drives cultural, economic, and social vitality and innovation. Their research suggests that intolerance of diversity hurts our well-being and ability to thrive. Research also shows that differences do make it harder for people to empathize with each other, but this is a prosocial skill that can be cultivated over a lifetime.
