When people are exposed to a more diverse group of people, their brains are forced to process complex and unexpected information. The more people do this, the better they become at producing complex and unexpected information themselves. This trains us to look more readily look beyond the obvious - precisely the hallmark of creative thinking.
Researchers have also found that creating and enjoying the arts can help us see things from a new perspective, by putting ourselves in a character's shoes. They can also create a feeling of connectedness and general kindness.
Opening ourselves to new experiences can seem hard to do, but it can help us cross divides and nurture new and inclusive friendships.
