# Publicity strategy and its negative impact Understanding how propaganda creates prejudice is an important step in preventing and identifying such harmful content. Some common propaganda techniques include： -**One-sided information selection**: Only show negative events or extreme cases, ignore positive content -**Labeling and generalization**: Use derogatory terms to attribute individual behaviors to the entire group -**Emotional manipulation**: Arouse insecurity through fear or threat narratives -**False correlation**: Linking unrelated social issues to specific groups -**Stereotype enhancement**: Repeatedly display a simplified image that conforms to prejudice These technologies have historically been used to create division and destroy social harmony. Identifying these strategies helps us cultivate critical media thinking, promote inclusive understanding, and resist the spread of prejudice. Promoting multicultural understanding, supporting fact-based reporting, and appreciating the unique values of different cultures are the correct directions for building a harmonious society.
