Gerbner's cultivation theory posits that prolonged exposure to television shapes audience perceptions, leading to standardized roles and behaviors, often manifesting as 'mean world syndrome,' where heavy viewers develop a cynical outlook on society. He argues that consistent media messages contribute to 'mainstreaming,' prompting viewers to adopt common beliefs and attitudes that reinforce societal stereotypes. The implications of this theory extend to how media content influences social dynamics, including perceptions of violence, gender roles, and cultural norms.
