Viewing televised violence increases rather than reduces aggressive behavior.

Evidence

The hydraulic metaphor of pent-up aggressive impulses pressing for discharge offers misleading causes and remedies for human violence. Individuals are helped more by learning to develop skills in anger management and better ways of coping with conflicts than by immersion in media violence or venting aggression. Contrary to predictions from catharsis theory, for reasons given earlier, exposure to televised violence increases rather than reduces the likelihood of aggressive behavior (Anderson et al., 2003; Anderson & Bushman, 2001; Bandura, 1973). — Albert Bandura, Moral Disengagement, 833
