Dave Grossman (born on 23 August 1956 in Frankfurt, Germany) is an American author who has specialized in the study of the psychology of killing, which has been termed "killology". He is a retired lieutenant colonel in the United States Army.
Grossman's career includes service in the U.S. Army as a sergeant in the 82nd Airborne Division, a platoon leader in the 9th Infantry Division, a general staff officer, a company commander in the 7th (Light) Infantry Division as well as a parachute infantryman, a U.S. Army Ranger and a teacher of psychology at West Point.
Grossman's first book, On Killing: The Psychological Cost of Learning to Kill in War and Society is an analysis of the physiological processes involved with killing another human being. In it, he reveals evidence that most people have a phobia-level response to violence, and that soldiers need to be specifically trained to kill. In addition, he details the physical effects that violent stresses produce on humans, ranging from tunnel vision, changes in sonic perception, and post-traumatic stress disorder.
His third non-fiction book, On Combat: The Psychology and Physiology of Deadly Conflict in War and in Peace, is an extension of the first, intended to provide coping strategies for dealing with the physiological and psychological effects of violence for people forced to kill in their line of work (soldiers and police officers).
Since his retirement from the Army, Grossman has founded the Killology Research Group and educates law enforcement officers and soldiers how to improve outcomes in lethal encounters. He also speaks at civilian events on ways to reduce violence in society and deal with the aftermath of violent events such as school shootings.
Grossman argues that the techniques used by armies to train soldiers to kill are mirrored in certain types of video games. The conclusion he draws is that playing violent video games, particularly light gun shooters of the first-person shooter-variety (where the player holds a weapon-like game controller), train children in the use of weapons and, more importantly, harden them emotionally to the task of murder by simulating the killing of hundreds or thousands of opponents in a single typical video game. Grossman uses blunt language that draws the ire of gamers—during the heights of video game controversy, he was interviewed on the content of his books, and repeatedly used the term "murder simulator" to describe first-person shooter games.
