Prejudice is a preconceived opinion or judgment about a person or group, often based on stereotypes rather than actual experience. It can lead to unfair treatment and discrimination against individuals because of their race, gender, religion, or other characteristics. For example, someone might assume that a person from a certain ethnic group is untrustworthy without knowing anything about them. This negative attitude can create barriers between people and foster a culture of misunderstanding. When prejudice exists, it can harm relationships and communities, making it difficult for individuals to connect with one another. Overcoming prejudice requires open-mindedness and a willingness to learn about others.
