The Invisible Gorilla

If a gorilla walked out into the middle of a basketball pitch, you’d notice it. Wouldn’t you? If a serious violent crime took place just next to you, you’d remember it, right? The Invisible Gorilla is a fascinating look at the unbelievable, yet routine tricks that your brain plays on you.


In an award-winning and groundbreaking study, psychologists Christopher Chabris and Daniel Simons asked volunteers to watch a 60-second film of a group of students playing basketball and told them to count the number of passes made. About halfway through, a woman dressed head to toe in a gorilla outfit slowly moved to centre screen, beat her chest at the camera, and casually strolled away. Unbelievably, almost half of the volunteers missed the gorilla.


As this astonishing and utterly unique new book demonstrates, exactly the same kind of mental illusion that causes people to miss the gorilla can also explain why many other things, including why:

honest eyewitness testimony can convict innocent defendants
expert money managers suddenly lose billions
Homer Simpson has much to teach you about clear thinking



Insightful, witty, and fascinating, The Invisible Gorilla closely examines the false impressions that most profoundly influence our lives and gives practical advice on how we can minimize their negative impact.
