In his groundbreaking bestseller "The Tipping Point," Malcolm Gladwell redefined how we understand the world around us. Now, in "Blink," he revolutionizes the way we understand the world within us. "Blink" is a book about how we think without thinking, about decisions that seem to be made at first glance – in the blink of an eye – which are, in reality, not as simple as they appear. Why are some people brilliant decision-makers while others are constantly clumsy? Why do some people follow their instincts and succeed, while others stumble into mistakes? How do our brains really function – in the office, in the classroom, in the kitchen, and in the bedroom? And why are the best decisions often those that cannot be explained to others? In "Blink," we meet the psychologist who has learned to predict whether a marriage will last based on just a few minutes of observing a couple; the tennis coach who knows when a player is about to act.
