Philosopher Dan Dennett makes a compelling argument that not only don't we understand our own consciousness, but that half the time our brains are actively fooling us.

  • Change blindness is a phenomenon where a person looks at a picture of a scene, but doesn't see enormous changes that occur in that scene when the changes are accompanied by a brief interruption like a cinema cut, a blank, or even small distractors like mudsplashes on a car windscreen.

It should come as no surprise that we don’t notice everything that we see. We all experience this on a regular basis – there is a great deal of visual information in our field of view but we only pay attention to a small fraction of it. Yet at the same time something within our vision can capture our attention if it flashes, moves, or otherwise changes dramatically enough. Interestingly, despite our common and frequent experience with the limitations of our own visual attention, people tend to have overconfidence in their ability to notice details and are often surprised when an important detail goes unnoticed.
