Seeing is 'Not Necessarily' Believing?

Recently, I read the Nature article, “Our useful inability to see the reality”that introduced a book called “Deviate: The Science of Seeing Differently”. I haven’t read the book yet, but this seems to shed some light on the idea of perception. The basic idea seems to be that we see what we want to see, based on our past experience, and not necessarily what’s out there in reality. In other words, the information we acquire from our eyes has much less to do with how we derive the actual meaning of it (in relation to ourselves of course). Specifically, it is being discovered that the 90% of the neurons that are responsible to make sense of what we see don’t consist of the visual fields in the brain.
