There are some common techniques and strategies used to lead the audience to prejudice against a particular group through entertainment programs or films. Here are some possible methods: 1. **Stereotype reinforcement**: repeatedly presenting stereotypes of a group so that the audience associates these characteristics with the entire group. For example, always presenting a group as villains, stupid or immoral characters. 2. **Selective display of negative behavior**: emphasizing the negative behaviors or characteristics of a particular group while ignoring its diversity and positive traits. This selective display will lead the audience to have an unbalanced view of the group. 3. **Lack of diversity**: portraying a group as a single, unchanging character, ignoring its internal diversity and individual differences, so that the audience believes that the group is homogeneous. 4. **Blame**: through plot settings, implying that the group is the root cause of certain social problems or conflicts, and blaming them. 5. **Humor and ridicule**: through humor or ridicule, derogatory views of a group are made acceptable or even entertaining, reducing the audience's vigilance against such prejudice. 6. **Contextual influence**: Presenting a group in a one-sided perspective in a specific social or historical context, making it seem to be naturally associated with some kind of disadvantage or hostility. 7. **Media bias**: The tendency to highlight negative news or events about a group in reports or plots, so that the audience forms a long-term negative impression. By being aware of these techniques, the audience can develop more critical viewing habits and resist the bias that may be conveyed by entertainment programs or film and television works. Creators can avoid unconsciously reinforcing bias through responsible production practices.
