Media effects on aggression are common, not limited to the disturbed

Evidence

This causal attribution makes internal pathology, rather than televised fare, a contributor to the harmful behavior. The problem with this explanation is that media effects are common occurrences, not rare ones. In the case of vicarious learning, virtually all viewers learn most, if not all, of the aggressive style of behavior being modeled (Bandura, 1965). In tests of performance effects of modeled aggression, it is not merely a few viewers who become more aggressive (Anderson & Bushman, 2001). Similarly, habituation and desensitization to human cruelty through massive exposure to televised violence is a common emotion-blunting phenomenon, not a selectively rare one. — Albert Bandura, Moral Disengagement, 922

Categorization

• XREF: Corroborates the vault claim that ordinary, non-pathological people adopt harmful attitudes and behaviors through exposure - same pattern behind how average citizens endorse racist policy without being ‘bad apples.’ — connects to: Media violence effects are common, not restricted to disturbed viewers
• DEFINE: Distinguishes vicarious learning (learning styles of behavior) from performance effects and desensitization as three separable common media effects.
• corroborated: 2 independent passages support this claim — Albert Bandura, Moral Disengagement: How People Do Harm…, 922
