In this wide-ranging third installment of Malcolm Gladwell's exploration of how people and social phenomena work, the New Yorker journalist takes a close look at what constitutes high levels of success. That is, what makes people at the top of their respective fields get there? As we've come to expect from Gladwell's previous books, the answer to the question is a bit complicated.
He says that upbringing, culture and even random luck have something to with success, but there is another important quality that anyone can control. Two chapters are dedicated to the "revelation" that IQ is only a baseline quality and success has little to nothing to do with having a high IQ or a low IQ. Rather, success is substantially a product of cultivating a high degree of what Robert Sternberg calls "practical intelligence" or what most refer to as "emotional intelligence."
Gladwell uses the example of Nobel laureates coming from unknown schools as often as ivy league schools. At this level of mastery IQ is no longer a factor. Success has little to do with where you were educated and everything to do with your level of practical/emotional intelligence and willingness to put in the 10,000 hours of practice required to reach mastery of your field.
All in all, it's an interesting read that isn't too heady and goes by pretty quickly, as the interesting anecdotes are what you would expect from Gladwell.

Blink is about the first two seconds of looking--the decisive glance that knows in an instant. Gladwell, the best-selling author of The Tipping Point, campaigns for snap judgments and mind reading with a gift for translating research into splendid storytelling. Building his case with scenes from a marriage, heart attack triage, speed dating, choking on the golf course, selling cars, and military maneuvers, he persuades readers to think small and focus on the meaning of ”thin slices” of behavior. The key is to rely on our ”adaptive unconscious”--a 24/7 mental valet--that provides us with instant and sophisticated information to warn of danger, read a stranger, or react to a new idea.

Gladwell includes caveats about leaping to conclusions: marketers can manipulate our first impressions, high arousal moments make us ”mind blind,” focusing on the wrong cue leaves us vulnerable to ”the Warren Harding Effect” (i.e., voting for a handsome but hapless president). In a provocative chapter that exposes the ”dark side of blink,” he illuminates the failure of rapid cognition in the tragic stakeout and murder of Amadou Diallo in the Bronx. He underlines studies about autism, facial reading and cardio uptick to urge training that enhances high-stakes decision-making. In this brilliant, cage-rattling book, one can only wish for a thicker slice of Gladwell's ideas about what Blink Camp might look like. --Barbara Mackoff

Intuition is not some magical property that arises unbidden from the depths of our mind. It is a product of long hours and intelligent design, of meaningful work environments and particular rules and principles. This book shows us how we can hone our instinctive ability to know in an instant, helping us to bring out the best in our thinking and become better decision-makers in our homes, offices and in everyday life. Just as he did with his revolutionary theory of the tipping point, Gladwell reveals how the power of blink' could fundamentally transform our relationships, the way we consume, create and communicate, how we run our businesses and even our societies.You'll never think about thinking in the same way again.
