As the authors of the Invisible Gorilla say:

We all believe that we are capable of seeing what’s in front of us, of accurately remembering important events from our past, of understanding the limits of our knowledge, of properly determining cause and effect. But these intuitive beliefs are often mistaken ones that mask critically important limitations on our cognitive abilities. . . . As we go through life, we often act as though we know how our minds work and why we behave the way we do. It is surprising how often we really have no clue.
