Gangs are usually seen to exist on the edge of society, In the Mafia, on the street corner, or among those engaged In people- or drug-trafficking. In this article I take a different approach and argue that, especially In response to trauma, gang functioning may be present at the very centre of our society, and is sometimes to be found in governmental, business, public and voluntary sector organisations, as well as the groups and teams within them. Using Nobel-prize winner William Goldings novel Lord of the Flies to give shape to my ideas, I develop a psychoanalytic theory of gang functioning. I draw in particular on Kleinian psychoanalytic ideas as well as concepts from the psychoanalytic study of groups and organisations. I argue that the establishment of the gang involves primitive splitting and projective identification and the perversion of adult authority. I suggest further that gang functioning involves the destruction of the sensory and communicative apparatuses that alert the gang to reality, coupled with the creation of a substitute, false reality. These features enable the avoidance of painful truths and experiences and facilitate the enactment of hatred that is so characteristic of ganging behaviour.
