" We are blinded by the effects of habit and hubris and hobbled by a poor understanding of our own limitations. We don't see all that we observe, and yet we sometimes “see” things we don't know we've seen. We can judge someone's honesty or likability in the blink of an eye, for instance, yet not notice a change in the identity of a person carrying a door right by us. "
