The other way to think about it is to say that we write because we want to understand the world better. Stories are about unusual people (or about the ways in which normal people are, after all, unusual) not just because they make for interesting reading, but because fiction writers want to stretch the limits of their understanding by exploring the unknown. The old saw, "write what you know" means something entirely different when placed next to the wisdom from the Tao Te Ching, "who knows that he does not know is the highest."
When we admit to misunderstanding the world, we admit that we are fallible. When we write to understand, we strive for improvement. Tell me about the ways in which you have misunderstood the world. Did your misunderstanding lead to great ideas?
