Blink: The Power of Thinking Without Thinking is a 2005 book by Malcolm Gladwell. It presents in popular science format research from psychology and behavioral economics on the adaptive unconscious; mental processes that work rapidly and automatically from relatively little information. It considers both the strengths of the adaptive unconscious, for example in expert judgment, and its pitfalls such as stereotypes.
Malcolm Gladwell in this startling book, “Blink” helps us to assess three crucial points. First, when a “snap judgment” is better than deliberate thinking. Second, when our unconscious (judgment) fails instead. And third, how we can actually train and control our impressions to avoid failures. The first quest is about expertise. Where does it come from? And when can we trust it?
