Behavioral economics is a multi-disciplinary field, linking economics, psychology, and neuroscience. It developed as a reaction against the prevailing view of rational economic man. The focus of behavioral economics is the actual psychology of human financial decision making. How do people make decisions about money? What are their blind spots? Where does emotion come in? The first decade of the twenty-first century has brought an explosion of research in this area of study. Some of the scientists involved include Daniel Kahneman, Amos Tversky, Daniel Ariely, Read Montague, and Richard Thaler. There have also been a number of books written by science journalists, such as Jonah Lehrer and Jason Zweig.
