"[T]he advantages of immigration aren't limited to those with particular academic backgrounds. In recent years, psychologists have discovered that exposing people to different cultures, either through travel abroad or diversity in their hometown, can also make them more creative. When we encounter other cultures we become more willing to consider multiple interpretations of the same thing. Take leaving food on one's plate: In China, it's often a compliment, signaling that the host has provided enough to eat. But in America it can suggest that the food wasn't good."
