I am looking for a textbook about cognitive biases. I have done a lot of searching on the internet, Amazon, etc, but all I have found are 'pop-psychology' books. I am looking for something in the style of the DSM-IV, and other textbooks by the American Psychiatric Association (such as 'Diagnosis of DSM-IV Personality Disorders'), so at the higher level, and more in-depth, less 'self-help' in style. I am wondering if anybody has read, or knows of a good textbook on this topic. Thanks for your help!
