No matter how carefully you think about what you're doing, no matter how realistic your view of the world seems to be, you're apparently fooling yourself. According to psychologists Christopher Chabris and Daniel Simons, our brains are hardwired to edit our perceptions and memories, to misinterpret evidence and jump to conclusions. They outline a variety of illusions the human mind falls prey to, some of which make intuitive (uh-oh - the goal of the book is to prove the unreliability of intuition) sense, including the fact that our brains edit information coming from our senses (we can all understand that if we noticed everything happening around us we could pay attention to none of it) and overconfidence (surprise! People who don't know very much about a subject overestimate how much they understand - I have some colleagues I'd like to hand that chapter to). Others were more startling - that in general people tend to believe the first "evidence" of a fact they receive, especially when it's presented emotionally, and they resist later evidence to the contrary, no matter how convincing (so it's not just those idiots from the other end of the political spectrum who do that!).
The Invisible Gorilla presents a lot of illuminating information that is well worth reading - it's both interesting and enlightening. I guess popular psychology books are expected to propose a solution to the problems they outline, so the final chapter offers somewhat less compelling suggestions for avoiding your brain's false intuitions. While on the one hand I was glad to discover that I'm a normal human, not an inattentive dummy (which is what I feel like when I'm driving, and I don't even own a cell phone!), on the other I was sorry to learn that there's not a whole lot of hope for change, barring a life of hyper-vigilance.
