To convince people of an extreme ideology, a storyline usually needs to include the following key elements: 1. **Clear enemy**: Set a clear "enemy" or "opposite", which can be a group, government, external force or some abstract concept. By portraying the enemy as a threat, people are more easily mobilized. 2. **Victim consciousness**: Describe how the main group in the plot is treated unfairly, oppressed or exploited, and inspire the group's sense of victimhood. This feeling can enhance solidarity and create a "us against them" mentality. 3. **Savior/hero**: Create a strong leader or idea as a symbol of hope that can save people from the water and fire and is the only solution. 4. **Utopian vision**: Propose a beautiful vision of the future, and after the idea is realized, depict an ideal state of life to inspire people to strive for it. 5. **Emotional resonance**: By using strong emotional elements such as anger, fear, hope and love, touch the audience and enhance the appeal and appeal of the story. 6. **Simplify complexity**: Simplify complex social problems so that ordinary people can easily understand and accept them. This simplistic narrative often ignores details and diversity, but facilitates the formation of a unified concept. 7. **Continued sense of crisis**: Creating a sense of urgency and a continuous sense of crisis makes supporting the ideology appear urgent and necessary, and delaying or opposing it is portrayed as dangerous. 8. **Exclusive group identity**: By emphasizing the uniqueness and superiority within the group, it deepens members' sense of belonging and loyalty, while devaluing external groups. Through these elements, a story can create a powerful psychological impact, making people more likely to accept extreme beliefs. However, it should be noted that stories that spread extreme ideologies are often harmful to society and require vigilance and critical thinking.
