Blink: The Power of Thinking Without Thinking

Blink was a great read for me. The whole idea that our brains make quick, accurate judgments long before we consciously process what’s happening is something I never really thought about until this book broke it down. Gladwell has a way of taking psychology and turning it into stories that pull you in, and this book is full of those moments where you stop and think, “Wow… I’ve done that without even realizing it.” What I liked most is how he explains the power of intuition—not as some mysterious feeling, but as a skill our minds build through experience, patterns, and exposure. Whether it’s experts judging art in seconds or everyday people reacting to situations before they fully understand why, the examples really drive home how much is happening behind the scenes in our decision-making. The book also made me more aware of how snap judgments can be both incredibly accurate and surprisingly flawed. There’s a balance between trusting your instincts and understanding when they might be influenced by bias or bad information. That’s something I’ve carried with me after reading. If there’s one thing to note, it’s that some chapters feel more connected than others—it’s not always a straight-line narrative. But even with that, the ideas stick, and the concepts are easy to apply to real life. Overall, Blink is a thought-provoking, enjoyable read that helped me understand my own thinking on a deeper level. It’s worth picking up if you’re interested in why we make the choices we do—often in the blink of an eye.

One of the primary criticisms of Gladwell's book, a criticism common to popular social science books, is that it covers the underlying research on an overly superficial level. I am not familiar with the scholarly work Gladwell relies upon, but if my experience in fields I am more familiar with holds, Blink certainly covers this corner of psychology on a superficial level. But that is ok. It would not be possible to write such a book otherwise. More important, in my mind, to this kind of book is that it clearly explain the consequences of the research to and spark some excitement for the subject in the lay reader. Blink achieves in spades on both counts. Blink is about snap judgments. Or, to put it another way, decisions made subconsciously, not consciously. Sometimes this is good (if you are an expert on the subject, for particularly complex decisions); sometimes this is bad (if the decision may be colored by subconscious, irrelevant biases). When Gladwell sticks to snap judgments (which he labels as "thin slicing"), Blink works. The stories are funny, relevant, and interesting. We discover that it is very difficult to really understand many, many things without years and years of experience and training, but we can still tell what is good and what we like. Gladwell uses jelly as an example, but take wine. I can tell you which wines I like and even tell you which wine I like better. But I cannot talk like a sommelier. And, as much of the research Gladwell discusses suggests, attempting to do so would interfere with my unconscious ability to differentiate good wine from bad. Gladwell also tries to show how we can use an understanding of thin slicing to make better decisions, but he tends to give answers that are less than fully satisfying. Gladwell relates how administrators at Cook County Hospital saved money and increased the accuracy of diagnoses by implementing a decision tree. It is an odd case study. Neither thin slicing nor conscious decision-making worked for the doctors; it was not an example of shifting from one to the other. It was an example of the power of narrowing focus to a few truly relevant metrics (a powerful and highly useful subject, but it is not the subject of Blink). In another case study, Gladwell never quite explains his point regarding the Kenna story, about a musician loved by record execs and ignored by the radio. Presumably he meant to imply that the thin slicing by the record execs was right (because they are experts), but the thin slicing by the radio focus groups was wrong (because they were not experts and could not identify music they would enjoy as quickly). Gladwell may be right, but that conclusion does not flow necessarily. Gladwell never really gives a solid basis for discerning when experts can be trusted. From Blink, it would be easy to over rely on experts. But a "sort of" expert can be worse than a layman. In the counterfeit statute case study Gladwell starts with, both those who got it right and those who got it wrong were experts. To give an example not in the books, literary "experts" have long denigrated the Lord of the Rings, while readers have had no trouble recognizing its brilliance (even if unable to explain why). The literary experts did not have the expertise to properly evaluate the expertise in philology and mythology that Tolkien used. Gladwell's final application of thin slicing shows a poor understanding of his own material. Gladwell observed that the percentage of female orchestra members shot up dramatically after a switch to screened auditions. Irrelevant visual signals were crowding out the relevant audio signals. Gladwell then extrapolates this to argue criminal defendants should be screened to mitigate subconscious racial bias. But a jury trial is not an orchestra audition. If a criminal defendant is on the stand in a jury trial, he visual cues are more important than the audio clues. As Gladwell discussed earlier in the book, facial expressions tell an indelible story about what a person is really thinking (he even uses an example from the OJ Simpson trial!). One of the primary duties of the jury is to assess the credibility of witnesses; how can they do this if they cannot see the person's face? That this recommendation achieved such quick support from an audience at Harvard Law School says more about the state of legal education than its merit.

`Blink' is about the mysterious two seconds it takes to develop a first impression and how surprising the impression often is, given our known preferences and tendencies. Malcolm Gladwell got the idea for this book after he had let his hair grow long on a whim, and found he was getting speeding tickets for the first time in his life. He wondered why the cops all of a sudden had an impression of him that wasn't there before. He became curious: where do first impressions come from anyway? Gladwell does some interesting investigative work to try to get some answers to that intriguing question. He suggests that `rapid cognition' is behind a `closed door' in our minds and follows certain unwritten rules. It is a logical process that he feels is not instinctual, but, surprisingly, can be more accurate than deliberate, rational thought, and follows certain rules that we are not even aware of. (Even improvisational comedians follow certain rules, though what they do often seems so random.) One must be careful though, since stereotyping and the immediate environment at the moment can influence the impression. All of this mental background action is going on without our even knowing it! The `closed door', it turns out, can only be peaked into. There are lots of very good examples of `blink'. There is the case of the statue that didn't look right to experts at first glance. Fourteen months later, after much testing, it was discovered by other experts that the statue was a forgery. Then there was the case of the supervisory fireman who yelled to his men to leave the building immediately minutes before it collapsed; he sensed something was wrong when it was not at all obvious what it was. Another example has to do with internationally known and respected tennis instructor who can almost invariably tell when a pro will double-fault just before the serve is hit, and he doesn't know how he does it! Speed dating often shows people being attracted others that do not fit their criteria of what they are looking for, for reasons they are fuzzy about. All of this is very mysterious, to say the least. Information and understanding are not the same things and sometimes less information is better. He gives very good examples of this in the medical and military fields. He talks about the `power of the glance', the ability of a great general to look at a battle field, weed through all the information, and make a rapid decision; he gives a great example of this in Lee's improbable victory at Chancellorsville. "Sometimes, we have to edit" our information down to something manageable, and make a decision on that. This was very counter-intuitive to me, and I'm sure, something to approach with caution. But I can't argue against results and he gives good evidence that it works. Be aware that first impressions can be misleading. Spontaneous decision making is shown to be not infallible, and can even be dangerous at times; stereotyping can supplant logical decision-making in a time-crunch. He goes into some detail about this with an instructive example of a police action in the Bronx that went awry. Gladwell said in the interview at the end of the book that he tried very hard to make this point. Rapid cognition can be your enemy as well as your friend. Use it with caution. It is tricky knowing how to measure the value of a product or a performer. Packaging can count too much, a great example of which is what he calls the `Warren Harding Error', a fascinating section of the book. Also, when surveying the response to a product, an opinion can't always be comfortably expressed in words (except by the experts), and as a result, some people will tend to look for a plausible reason, and give an incorrect opinion. The mystery of why someone likes something can't always be codified. This was a fascinating book that does not pretend to give all the answers but does raise some really good questions about a mysterious and important subject. The so-called `locked door' is finally getting its due.

Bel libro, interessante. Aiuta a capire come funziona la prima impressione. Lo consiglio a chiunque sia interessato ai meccanismi del cervello!

Malcolm Gladwell explores how we make decisions, especially snap decisions and comes to some very interesting and profound conclusions. As an analytical sort of person I tend to rely on gathering as much information as possible before making a decision, and then still taking my time about it. The book shows that sometimes we can have too much information and that sometimes the snap judgements, aided by extensive experience, can be more accurate. Gladwell also looks at how instinctive judgements can be badly lead, the causes for these and the sort of unwanted results, even tragedies, this can lead to. His conclusion sets out ways we can overcome biases caused by these conditioned judgements. This all done in Gladwell’s incredibly engaging style of wonderfully spun true stories that illustrate something profound. Even if you learn nothing from the book, it’s worth reading it just the cases and stories and how he tells them. All in all, it’s wonderfully enthralling and thought-provoking reading.

Je recommande ce livre a tous. Ça peut vraiment aider dans nos relations aux autres et dans la compréhension des autres.

Great book and it arrived in great conditions

Lo compré porque me salió anunciado en un libro de árboles, y me atrajeron las reseñas. Es fácil de leer, y te mantiene enganchado porque usa anécdotas del mundo real y te las va analizando "científicamente". También te da algunos consejos para "mejorar" tu intuición.
