Practical Thinking

How is it that in an argument both sides are always right? Dr. Edward de Bono bases this book on the Black Cylinder Experiment, with 1,000 participants, from which he derived that debaters fall into four categories of "rightness": emotional, logical, unique, and recognition rightness. In addition to exploring these four states, de Bono names five levels of understanding and five major mistakes of thinking.
