Predictably Irrational demonstrates how irrationality manifests itself in situations (often very peculiar and hilarious) where rational thought is expected. In this astounding book, groundbreaking in scope and totally original, Dan Ariely cuts to the heart of our strange behaviors and presents outstanding material that will keep every reader transfixed. He explains why honor codes are actually effective in reducting dishonesty in the workplace, why a 50-cent aspirin can cure a headache that a one-cent aspirin cannot, and, ultimately, why we make decisions contrary to our better judgement. Predictably Irrational will help readers make better choicesin their personal lives, their business lives, and about our collective welfare.

Our customer reviews

First of all this version of the book is the small size one just fyi. Dan Ariely offers good insights on how people really make their decisions (behavioral economics) versus how it is thought they make them (economics). I enjoyed his experiments and the outcomes, especially intriguing was one conducted on men who were in 'an aroused state' - it appears one can really not think straight in this condition which is rather frightening and brings up many questions. What I didn't enjoy as much were his own elaborations on those experiments, I don't mean the conclusions but rather what he continued to write based on these conclusions...if a book is about scientific research I don't think he should've written about his own opinion so much but that's just what I think and that part was not my cup of tea. Some of it just went way off initial research and topic and felt more like a book about his own ideas about the society. But since it is his book he has that right. Overall I would recommend this book because it did have interesting facts presented there and a few surprising more
