Blink: The Power of Thinking Without Thinking (2005) is Malcolm Gladwell's second book. 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.

Summary

The author describes the main subject of his book as "thin-slicing": our ability to use limited information from a very narrow period of experience to come to a conclusion. This idea suggests that spontaneous decisions are often as good as—or even better than—carefully planned and considered ones. To reinforce his ideas, Gladwell draws from a wide range of examples from science and medicine (including malpractice suits), sales and advertising, gambling, speed dating (and predicting divorce), tennis, military war games, and the movies and popular music. Gladwell also uses many examples of regular people's experiences with "thin-slicing," including our instinctive ability to mind-read, which is how we can get to know a person's emotions just by looking at his or her face.

Gladwell explains how an expert's ability to "thin slice" can be corrupted by their likes and dislikes, prejudices, and stereotypes (even unconscious ones). Two particular forms of unconscious bias Gladwell discusses are implicit association tests^[1] and psychological priming.

Gladwell also mentions that sometimes having too much information can interfere with the accuracy of a judgment, or a doctor's diagnosis. In what Gladwell contends is an age of information overload, he finds that experts often make better decisions with snap judgments than they do with volumes of analysis. This is commonly called "Analysis paralysis." The challenge is to sift through and focus on only the most critical information. The other information may be irrelevant and confusing. Collecting more information, in most cases, may reinforce our judgment but does not help make it more accurate. Gladwell explains that better judgments can be executed from simplicity and frugality of information. If the big picture is clear enough to decide, then decide from this without using a magnifying glass.

The book argues that intuitive judgment is developed by experience, training, and knowledge. For example, Gladwell claims that prejudice can operate at an intuitive unconscious level, even in individuals whose conscious attitudes are not prejudiced. An example is in the halo effect, where a person having a salient positive quality is thought to be superior in other, unrelated respects. Gladwell uses the 1999 killing of Amadou Diallo, where four New York policemen shot an innocent man on his doorstep 41 times, as another example of how rapid, intuitive judgment can have disastrous effects.^[2]

Research and examples

The book begins with the story of the Getty kouros, which was a statue brought to the J. Paul Getty Museum in California. It was thought by many experts to be legitimate, but when others first looked at it, their initial responses were skeptical. For example, George Despinis, head of the Acropolis Museum in Athens, said "Anyone who has ever seen a sculpture coming out of the ground could tell that that thing has never been in the ground". Gradually, the argument for the legitimacy of the kouros' provenance fell apart. The letters tracing its history turned out to be fakes, referencing postal codes and bank accounts that did not exist until after the letters were supposedly written. However, experts to this day are unsure whether the kouros is authentic or not. The museum notes that "anomalies of the Getty kouros may be due more to our limited knowledge of Greek sculpture in this period rather than to mistakes on the part of a forger."^[3]

The studies of Paul Ekman, a psychologist who created the Facial Action Coding System (FACS), indicates that a lot of "thin slicing" can be done within seconds by unconsciously analyzing a person's fleeting look called a microexpression. Ekman claims that the face is a rich source of what is going on inside our mind and although many facial expressions can be made voluntarily, our faces are also dictated by an involuntary system that automatically expresses our emotions.^[5]

Reception

In Think!: Why Crucial Decisions Can't Be Made in the Blink of an Eye (Simon and Schuster, 2006), Michael LeGault argues that "Blinklike" judgements are not a substitute for critical thinking. He criticises Gladwell for propagating unscientific notions:

As naturopathic medicine taps into a deep mystical yearning to be healed by nature, Blink exploits popular new-age beliefs about the power of the subconscious, intuition, even the paranormal. Blink devotes a significant number of pages to the so-called theory of mind reading. While allowing that mind-reading can "sometimes" go wrong, the book enthusiastically celebrates the apparent success of the practice, despite hosts of scientific tests showing that claims of clairvoyance rarely beat the odds of random chance guessing.^[8]

Nobel prize winner Daniel Kahneman, author of Thinking, Fast and Slow which speaks to rationality's advantages over intuition, says:

Malcolm Gladwell does not believe that intuition is magic. He really doesn't...But here his story has helped people, in a belief that they want to have, which is that intuition works magically; and that belief, is false.^[9]

In an article titled "Understanding Unconscious Intelligence and Intuition: Blink and Beyond", Lois Isenman agrees with Gladwell that the unconscious mind has a surprising knack for 'thinking without thinking' but argues that its ability to integrate many pieces of information simultaneously provides a much more inclusive explanation than thin-slicing. She writes:

Gladwell often speaks of the importance of holism to unconscious intelligence, meaning that it considers the situation as a whole. At the same time, he stresses that unconscious intelligence relies on finding simple underlying patterns. However, only when a situation is overwhelmingly determined by one or a few interacting factors is holism consistent with simple underlying signatures. In many situations, holism and simple underlying signatures pull in different directions.^[10]
