    Dan Ariely(Author) Simon Jones(Narrator)

Why do smart people make irrational decisions every day? The answers will surprise you. Predictably Irrational is an intriguing, witty and utterly original look at why we all make illogical decisions.

Why can a 50p aspirin do what a 5p aspirin can't? If an item is "free" it must be a bargain, right? Why is everything relative, even when it shouldn't be? How do our expectations influence our actual opinions and decisions?

In this astounding book, behavioural economist Dan Ariely cuts to the heart of our strange behaviour, demonstrating how irrationality often supplants rational thought and that the reason for this is embedded in the very structure of our minds.

Predicatably Irrational brilliantly blends everyday experiences with a series of illuminating and often surprising experiments, that will change your understanding of human behaviour. And, by recognising these patterns, Ariely shows that we can make better decisions in business, in matters of collective welfare, and in our everyday lives from drinking coffee to losing weight, buying a car to choosing a romantic partner.

Review Text

    Economists used to assume that most people made rational decisions but psychologists have proved them wrong. Not only are we irrational, but most of us are irrational in similar ways, hence the title. Even after reading this book, I'd probably still be attracted to a 'free' offer.Behavioural economics is proving a rich seam for authors, but very few are as entertaining as Dan Ariely. He has an engaging writing style and most of the experiments he recounts are his own, even the delightfully wacky ones, such as giving out free beer or asking young men to complete a questionnaire when sexually aroused. Fortunately, this last one was carried out in the privacy of their own rooms.

    Interesting and clearly written. Consequences of the data was not, however, pursued. Fairly short- author has written several books- perhaps less of greater length would be better.

    I really enjoyed listening to this in the car. It makes long journeys fly by. And it is the type of audio cd you can listen to again and again.

    It was an interesting insight into behavioural economics, and certainly some of the experiment results are amazing, it was just a bit repetitive and ended abruptly without myxh of a general overview.

    Classic and well worth reading if you're interested in Behavioural science.

    This is really a popular psychology book about how we behave and how, as the subtitle puts it, hidden forces influence our everyday decisions. So don't be put off by quotes from businessmen and economists in the blurb. I almost was. But I'm glad I wasn't. This is a neat little book with plenty of nuggets of information and insights that you can put to use immediately. You learn things about yourself and other people that seem so obvious you wonder how you'd never noticed them before and you learn why hunches you've had in the past really are right. Each chapter of this book consists of some simple experiments that are designed to probe a different aspect of our decision-making process e.g. how our expectations affect how we experience things and why too many choices can be unhelpful, to mention just two. The experiments are simple and elegant.They usually consist of asking two or more differently informed groups of students questions about something. Actually, sometimes the author is a bit vague about the exact experimental conditions, how bias was eliminated from the experiment (particularly with respect to how questions were framed [what language was used] and how the participants were chosen [a few samples were decidedly small]) and how the many variables were isolated and controlled. So in that sense we must take Ariely's word for it. Also, he often vaguely summarises the results of these experiments with words such as "more than" and "most" instead of giving figures. If he were giving a lecture I would have asked him to clarify quite a few points. But all in all I think that this was an interesting book albeit a short one. It is a slim volume and the typeface is quite large. I'm a slow reader and I read it comfortably over two days.
