"Since the publication of the first edition of Head Strong: How Psychology is Revolutionizing War in 2014, developments in military psychology have been rapid and important. So much so, that this revised edition is necessary to accurately capture the vital role that psychology continues to play in 21st century military success. The ideas contained in the first edition influenced emerging doctrine in the Army's Human Dimension, and informed military leaders around the globe of ways that psychological science and practice may be leveraged to improve combat effectiveness. Many of the predictions made in the first edition have come true, and new and exciting products of military psychology now offer novel ways of impacting military outcomes. This revised edition of Head Strong updates the 13 chapters included in the first edition with breaking news in military psychology, and adds new material to augment those chapters. Two entirely new chapters are included in this edition. The first is on character and discusses how to measure it, how to develop it, and how character plays a vital role in the performance of individual soldiers and their units. The second new chapter is based on a year-long special assignment the author spent working as a Fellow for the Army Chief of Staff's Strategic Studies Group, and captures the rapid developments in psychology, cognitive neuroscience, and other disciplines that may help the military optimize soldier and unit performance. Like the other topics in Head Strong, these two new chapters have significant applicability to non-military organizations including schools, corporations, and sports teams. Taken together, the updates and new chapters make Head Strong, Revised Edition essential reading for anyone interested in how the military, and by extension other organizations, may leverage psychology to improve performance."--
