The Negative Impact of Positive Thinking

Since the 19th Century, it's been an article of American faith that positive thinking can lead to better health, prosperity and success. In recent years, that idea has been turned into a "minor industry." But has too much positive thinking made us blind to the realities of disease, economic insecurity and the prospect of failure? "The official belief that things are good and going to get better" helped cause September 11, miscalculations about Iraq and the current financial disaster. That's according to a new book that calls positive thinking a form of "mass delusion." We talk with author Barbara Ehrenreich and others.
