Review
“A fireworks show of insights into how our minds work. If you want to avoid tripping on cognitive errors, read this book.” — Iris Bohnet, Professor and Academic Dean, Harvard Kennedy School, Director of the Harvard Decision Science Laboratory
“Dobelli examines our most common decision-making failings with engaging eloquence and describes how to counter them with instructive good sense.” — Robert Cialdini, author of Influence
“…a serious examination of the faulty reasoning that leads to repeated mistakes by individuals, businesses, and nations…In this fascinating book, Dobelli does not offer a recipe for happiness but a well-considered treatise on avoiding ‘self-induced unhappiness.’” — Booklist (starred review)
“…easy-going prose…what [Dobelli] does is pinpoint exactly the assumptions, bias and illusions that shape our thinking and decision-making processes in both business and personal relationships that can cost us dearly as individuals and as a society.” — Financial Times
From the Back Cover
Have you ever . . .
- Invested time in something that, in hindsight, just wasn't worth it?
- Paid too much in an eBay auction?
- Continued to do something you knew was bad for you?
- Sold stocks too late, or too early?
- Taken credit for success, but blamed failure on external circumstances?
- Backed the wrong horse?
These are examples of what the author calls cognitive biases, simple errors all of us make in day-to-day thinking. But by knowing what they are and how to identify them, we can avoid them and make better choices: whether in dealing with personal problems or business negotiations, trying to save money or earn profits, or merely working out what we really want in life—and strategizing the best way to get it.
Already an international bestseller, The Art of Thinking Clearly distills cutting-edge research from behavioral economics, psychology, and neuroscience into a clever, practical guide for anyone who's ever wanted to be wiser and make better decisions. A novelist, thinker, and entrepreneur, Rolf Dobelli deftly shows that in order to lead happier, more prosperous lives, we don't need extra cunning, new ideas, shiny gadgets, or more frantic hyperactivity—all we need is less irrationality.
Simple, clear, and always surprising, this indispensable book will change the way you think and transform your decision making—at work, at home, every day. From why you shouldn't accept a free drink to why you should walk out of a movie you don't like, from why it's so hard to predict the future to why you shouldn't watch the news, The Art of Thinking Clearly helps solve the puzzle of human reasoning.

- Reviewed in the United States on May 14, 2013Format: HardcoverVerified PurchaseMany know that Wikipedia has a "mistake" list of potential cognitive errors and biases that links to nearly infinite mistakes these poor brains can make! This is like the little book of 100 things that can go right vs. the 2,000 page book of clinical maladies that can descend upon us each unsuspecting day.
This read is truly an eye-opening joy ride! Even though the author claims happiness is genetic and not to expect too much, hey, get this, it's enlightening AND entertaining! How is it better than the plethora of error books and self help sites out there, as well as Wiki's extensive list? Wow, no comparison. Dobelli uses short, punchy "chapters" that are almost just a few paragraphs to explain, define, exemplify and illustrate each cognitive trap, error and bias-- astonishing. The humor is dry but everywhere, especially his many "aha" insights about how these errors helped us keep from being killed as cave folk but do us disservice now. He wryly shares that the guy who questioned the herd mentality probably didn't contribute to the gene pool if he did so while all his buddies were running from a lion! This author's sense of humor is too contagious.
As you get through the first few "chapters" your mind will be reeling with the insights-- they really are more subtle than the fun tone suggests at first. Then, you look at the 300 pages that remain and realize how PACKED this book is with eye opening insights-- wow. This is one of those rare books after which you never look at the world, your life, or your relationships the same, EVER again!
Even if you've studied these mistakes and biases for years, or are an expert in the field (an "authority?" oh, oh), Rolf's "multiple angle" style of illustration, story telling, examples, descriptions and taxonomy really drives the trap home in deeply understandable, gut ways you might not have experienced with other authors. A dry topic like exit barriers is generalized with an error about sunk costs, and examples given for everything from relationships to habits, never mind investments! Though he is a friend of Taleb's, don't believe the hype that this is a "business" or investing book-- its examples and applications range much farther than that universe, down to our daily unconscious choices and patterns.
Highly recommended for anyone who enjoys seemingly light page turners that turn out to be much deeper and life changing. NOT a self help tome, in fact he makes great fun of self helpers, showing them the covariate mirror where they ignored their own genetics and luck to get there, having nothing to do at all with the "techniques" they are now espousing and promoting. Best of all, this is a guy who continually makes fun of himself and tells many stories about his own "stupidity" -- subtly teaching us he's caught on to the subtlest trickster of all-- ego.

- Reviewed in the United States on April 12, 2017In the 1960s psychologists began to examine scientifically, how people think, decide and take action. The result, explains the author of this book, Rolf Dobelli, was a “theory of irrationality that states: thinking is in itself not pure, but prone to error.” This, they found, was true of all people, including the highly intelligent, resulting in everyone falling into the same cognitive errors.
More interestingly, it appears we all “systematically err in the same direction.” If this is indeed true, it means we all make predictable mistakes. If it is true, and it appears to be, we should be able to fix at least some of them and avoid making these errors in our lives.
Dobelli has gathered 99 errors common to us all. He provides short, amusing and pithy insights into their form and causes. This has not made his life error free, he reports. However, “to make things simple, I have set myself the following rules: in situations where the possible consequences are large, I try to be as reasonable and rational as possible when choosing… In situations where the consequences are small I forget about rational optimisation and let my intuition take over.”
This book is a useful compendium of error. Reading this book will certainly increase one’s awareness of possible errors, which will lead to better decisions. To illustrate, I have chosen five errors of the Dobelli’s 99.
Social Proof
You are roaming the Serengeti some 50,000 years ago, and your hunter-gather companions suddenly break into a desperate run away from some disturbance. What should you do? Mindlessly follow, or consider the possibility that it is a gazelle rather than a predator. Having seen a thoughtful companion become some animal’s lunch you run with the crowd.
“Social proof” is the legacy of this herd instinct that dictates that individuals are behaving correctly when they act the same as other people. Social proof is behind stock market bubbles, as well as stock market stampedes. It is no different in the worlds of fashion, management techniques, and diets.
Social proof informs even simple decision such as selecting a restaurant in an area with which you are unfamiliar. It seems sensible to choose the one that is full over a poorly patronised one.
Novelist W. Somerset Maugham put the error of social proof succinctly: ‘If 50 million people say something foolish, it is still foolish.’
Sunk Cost Fallacy
The film was awful. After an hour, Dobelli whispered to his wife: ‘Come on, let’s go home.’ She replied : ‘No way. We’re not throwing away $ 30.’ The $ 30 is not reason to stay, that would be a thinking error. The money was been spent, and will not be returned. This is an example of the sunk cost error.
So often in business, there is the sense that having invested so much, it would be wrong to stop now. Stopping now, makes the investment seem a mistake. The sunk cost fallacy is most dangerous when we have invested time, money, energy, commitment or love in something.
The need for consistency drives this type of irrational behaviour. Deciding to cancel the project before it is completed is to admit that we had made a mistake.
Sometimes the consequences of this thinking error costs lives as when America extended their involvement in the Vietnam War. Their thinking: ‘We’ve already sacrificed so much for this war; it would be a mistake to give up now.’
Reciprocity
Psychologist Robert Cialdini has studied the phenomenon of reciprocity and concluded that people have discomfort feeling they are indebted to another person.
Dobelli offers this example: “A supplier of screws invites a potential customer to join him at a big sports game. A month later, it’s time to order screws. The desire not to be in debt is so strong that the buyer gives in and places an order with his new friend.”
This phenomenon has a long history. When primitive man’s food supplies were subject to high fluctuations, he needed others to share their food with him. When he killed an animal too large to eat in one day, he would share the meat with others in his group. Doing this would ensure that they share their meat with him when he is short.
When approached in the supermarket, with an offer of a taste of wine, a chunk of cheese or a handful of olives, Dobelli advises to refuse the offer. The error of reciprocity has led many to ending up a pantry full of goods they do not even like.
Contrast Effect
We judge something to be beautiful, expensive or large only if we have something ugly, cheap or small to compare it to.
Experiments indicate that people will walk an extra ten minutes to save $ 10 on food. The same people, however would not walk ten minutes to save $ 10 on a $ 1,000 suit. The whole category of discount business is only viable because of this error, Dobelli claims.
In the investment arena, the error leads people to believe a share is good value because it is 50% below the peak price. The share price is what it is, and comparison is irrelevant. All that matters is whether the share goes up or down in the future.
The contrast effect also plays out in the social arena. If you are dating it is not prudent to double date with your supermodel friend. This makes you appear less attractive than you really are!
Chauffeur Knowledge
According to Charlie Munger, Warren Buffett’s business partner, there are two types of knowledge. “Real knowledge” is what people have when they have invested time and effort to understanding a topic. “Chauffeur knowledge” is the result of learning how to put on a show. Warren Buffett uses the phrase, ‘circle of competence’ to avoid this error. ‘You have to stick within what I call your circle of competence. You have to know what you understand and what you don’t understand. It’s not terribly important how big the circle is. But it is terribly important that you know where the perimeter is.’
It is so easy to not confuse the company spokesperson, the newscaster, and the cliché generator with those who possess true knowledge. You can recognize the difference because the true experts know what they know and what they do not know.
This book is a “must read!” We cannot do enough to protect ourselves from our thinking errors and the author sites 99 such errors. Much of the material in this book can be found scattered elsewhere. The value of this book is that the information is in one place.
