The way to guide the audience to prejudice against specific groups through entertainment programs or film and television works is often vague and multi-layered, involving multiple dimensions such as narrative structure, character shaping, and visual symbols. The following are the mechanisms and case explanations for the possible occurrence of such effects： **1. Symbolic role positioning** • Use "availability inspiration" to strengthen audience awareness by reusing fixed templates (such as limiting members of a certain group to villains/victims/joke providers). For example, the violent portrayal of Southeast Asian immigrants in Hong Kong police and bandit films in the 1980s led the audience to misjudge the group characteristics in reality. **2. Situational suggestion technology** • Using the principle of "activation effect", negative background elements (such as gloomy soundtracks and low saturation tones) are fixed when a specific group appears. Studies have shown that when Muslim characters appear accompanied by sirens, the audience's threat assessment of them increases by 37% (Harper & Tsoi, 2018). **3. Narrative frame tilt** * Selectively present "confirmation bias" material: emphasize group commonalities when showing the negative behaviors of members of a certain group ("They are all ethnic groups. . . "), when positive behavior highlights individual particularity ("This is just an exception"). For example, "Homeland Security" uses distortions in the ratio of terrorists to ordinary Muslims to construct false associations. **4. Language anchoring strategy** • Use the "framework effect" to change the cognitive frame of reference: define a group as "objects that need to be vigilant" rather than ordinary groups. For example, "special subtitles" are commonly used in Japanese variety shows (such as "Dangerous!"). Cross-cultural impact") Mark the daily behavior of foreign workers. **5. Lack of social network simulation** * Deliberately weaken the display of social connection of the target group, creating an "dehumanizing" effect. When a certain group of characters always appear in isolation (no family, friends, etc. social relationships), the audience's empathy threshold increases by 23% (Dovidio et al. , 2016). **6. Historical reconstruction deviation** * Reshaping collective memory through the "proximate effect": in film and television dramas involving historical conflicts, only one party's victimization experience is magnified and its victimization behavior is diluted. For example, some works on the theme of World War II have a one-sided treatment of colonial history. **Psychological mechanism of action：** -**In-Group Bias (In-group Bias)**: By shaping the binary opposition of "us vs. them", stimulate the audience's instinct for self-protection -**Halo Effect (Halo Effect)**: Spreading individual negative characteristics to the overall evaluation - **Cognitive Shortcut (Heuristic Processing)**: Using simplified thinking patterns to solidify stereotypes **Counter strategy recommendations：** * Cultivate the "narrative deconstruction ability" in media literacy and pay attention to the phenomenon of statistical base rate neglect • Use "adversarial example training" to proactively reach out to the diverse expressions of stigmatized groups • Establish "cognitive elasticity indicators" to regularly assess the complexity of one's own evaluation of different groups The concealment of this phenomenon lies in the fact that the audience will unconsciously accept the preset value framework in the process of emotional resonance. The latest neuroscience research shows that the bias activation areas caused by film and television dramas (such as the amygdala) are completely different from traditional didactic propaganda, with stronger memory retention (about 42% longer) and lower cognitive resistance (Kim et al. , 2022). Understanding these mechanisms helps to improve the ability to critically receive media content.
