Although I am not a professional in this area, I have had many experiences that required me to learn how people make decisions. This book goes a long way toward explaining these processes and provides plenty of examples to learn from. Not only does Gary Klein present his results, he covers how the data were obtained, its analysis, his assumptions, and how the conclusions were reached. It provides great insight into one's own thinking and decision making process. I was truly amazed at how readable this book was and how thoroughly real life examples were analyzed. I would recommend it to anyone in any field.
