Sway: The Irresistible Pull of Irrational Behavior is yet another addition to the rapidly growing body of works written to introduce the average schmo to the wonders of behavioral economics. Written by Ori Brafman and Rom Brafman, this is an quick and easy introduction to cognitive biases and how they affect our everyday lives.
There is no central theme to this book, other than that humans are not rational animals. They focus primarily on the biases of loss aversion, value attribution, and the diagnosis bias, although they touch on others along the way. They base their discussion firmly on science, although they avoid the technical details of the experiments and don't get bogged down in analyzing the results further than needed to make their points. They use a lot of anecdotal examples, although they avoid using these examples as evidence. This book makes a good introduction to behavioral economics and cognitive biases, and it is enjoyable and educational even if you already have some knowledge in these areas. Sway is very much reminiscent of books like Freakonomics and Blink in terms of readability and entertainment.
