The Invisible Gorilla was about how our minds deceive us into believing we see more than we actually do. We actually miss a ton of information when we’re looking around. The book was named after an infamous selective attention task involving basketball players passing a basketball back and forth. I won’t ruin the experiment for you, but if you would like, you can read about it here. I really enjoy books that mix science and storytelling in a compelling way. Christopher and Daniel did just that.
