The document discusses different influences on human aggression, including pornography, television, and group influences. Pornography can decrease attraction to partners, increase acceptance of extramarital sex and women's submission, and cause men to perceive women sexually. Television can increase aggressiveness through arousal, disinhibition, and imitation, as well as desensitize viewers to violence. Group influences can amplify, magnify, polarize, and accentuate natural aggressive behaviors. Suggested remedies include education campaigns and reducing exposure to violent media and aggressive groups.
