Still the best popular book on this topic,
By
This review is from: Irrationality (Paperback)
This is a wonderful achievement of science popularisation. Sutherland had a gift for succinctly and non-technically summarising psychology experiments. In this book he surveys more than one hundred and sixty different studies that expose failings of human reasoning and judgement. Overconfidence, conformity, biased assessment of evidence and inconsistency are among the follies given their own chapters. One chapter deals with organizational (bureaucratic) irrationality.
The point is not the banal one that there are stupid people about. It is that we all make systematic errors and biases that can lead to disaster in predictable ways. The example applications include reasoning about medical tests, military disasters, the paranormal, the Rorschach test, gambling and daft purchasing decisions. If society took the recommendations in this book, we would give up job interviews, stop awarding school prizes, totally reform the procedures for criminal trials and change many of the incentive structures we use to motivate people. Each chapter ends with a set of personal lessons for minimising the damage of one's inevitable human irrationality. This is a potentially very depressing book, but its humiliating lesson is one that, for a better public life and personal life, we need to learn. You can either learn it from a huge corpus of technical psychology literature or from this little paperback.

The Vulcan bible and the big decision-maker's best friend,
By
This review is from: Irrationality (Paperback)
We all act on impulse and make quick decisions every day. That may be irrational but if we had to think long and hard about every decision we made then our lives would never get anywhere.
Fortunately, most of our decisions have very limited consequences if they turn out to be wrong, but sometimes a bad decision can cost a lot of money, even human lives. Then it is best to be sure that the decision was the best possible based on all the facts. Even when buying a new home or a new car, one could well save oneself some grief and perhaps a lot of money if the deal was approached in a rational manner. As this book points out, many lives and lots of money have been lost and many projects have failed because of bad decisions due to pride, prejudice, by misinterpreting facts in ones own favor, by fear of non-conformity and many other irrational reasons. This book is an excellent tour through a lot of topics, all of which are aspects of irrational behavior. Through many (painfully :-/ ) clear examples the author illustrates the various types of irrational behavior and how they can lead to bad or wrong decisions. For example, the "availability error" where too much emphasis is put on whatever comes first to mind, or the "halo effect" where too much emphasis is put on first impressions. These traps catch us every day and are among the advertisers' best weapons. If you want to improve you own decision making - in you personal life as well as you professional life - or you just want to know why other people often make such bad decisions this book can give you a lot of insight into how easily people can make flawed decisions and thus what to be wary of the next time you face an important decision. English is not my first language but I use English a lot. With this background I found the book fairly easy to read, although it is my impression that you do need to be quite proficient in the English language to get the full benefit of the book. For those seeking more information about the topics and examples presented by the author, the book has a comprehensive list of the background material, with reference to the page where it is used, as well as a list of supplemental literature for the curious reader. I warmly recommend this book to any Vulcan wannabe as well as to any person with the responsibility to make decisions that can affect other people's lives, jobs, careers, health etc.

Essential reading - Changes your way of thinking,
By
This review is from: Irrationality (Paperback)
On reading this book you are a presented with everyday problems and the simply irrational way we make decisions- from leaving the cinema to international travel. This non-technical tale provokes thinking in a way that does not confuse the reader, but keeps them enthralled throughout- always wanting to read the next section.
To give you an idea- here is one of the simple irrationalities presented to us- You've paid to go and see a film, but don't like it- do you leave early? Whilst most people would say no, this book tempts us to say yes and shows us that this the logical way to do things. Essentially do we waste our time and money (and stay in the cinema) or just our money? Surely we should cut our losses and leave, but irrationality shows that in fact we don't we stick around in a way that shows our poor decision making. Overall, irrationality presents solid arguments in a way thats easy to understand. A fantastic book.
