The key to good decision making is not knowledge. It is understanding. - Malcolm Gladwell

Kids don't watch when they are stimulated and look away when they are bored. They watch when they understand and look away when they are confused. If you are in the business of educational television, this is a critical difference. It means if you want to know whether-and what-kids are learning from a TV show, all you have to do is to notice what they are watching. And if you want to know what kids aren't learning, all you have to do is notice what they aren't watching. Preschoolers are so sophisticated in their viewing behavior that you can determine the stickiness of children's programming by simple observation.

The entire principle of a blind taste test was ridiculous. They shouldn't have cared so much that they were losing blind taste tests with old Coke, and we shouldn't at all be surprised that Pepsi's dominance in blind taste tests never translated to much in the real world. Why not? Because in the real world, no one ever drinks Coca-Cola blind.

“Outlier” is a scientific term to describe things or phenomena that lie outside normal experience. In the summer, in Paris, we expect most days to be somewhere between warm and very hot. But imagine if you had a day in the middle of August where the temperature fell below freezing. That day would be outlier. And while we have a very good understanding of why summer days in Paris are warm or hot, we know a good deal less about why a summer day in Paris might be freezing cold. In this book I’m interested in people who are outliers—in men and women who, for one reason or another, are so accomplished and so extraordinary and so outside of ordinary experience that they are as puzzling to the rest of us as a cold day in August.
