Anger is one of the forces that has sparked protests across the Middle East, from Egypt to Libya to Syria. It can be a motivating force, but it can also be destructive and damaging when it goes unchecked. On this week’s Please Explain, we’re taking a look at the roots and consequences of anger. Dr. Philip Muskin, Professor of Clinical Psychiatry, Columbia University Medical Center, and Dr. Howard Kassinove, Professor of Psychology and Director, Institute for the Study and Treatment of Anger and Aggression, and author of Anger Management: The Complete Treatment Guidebook for Practitioners and Anger Management for Everyone, explain when anger becomes a problem and how anger management works.
