Stereotypes are simplified representations that focus on certain characteristics of a group and assume they apply to all members. They are used by media to communicate information quickly but also reflect existing stereotypes in culture, potentially reinforcing them. While stereotypes may contain elements of truth, they overlook cultural reasons for traits and make negative judgments, not allowing for individual diversity. Positive stereotypes have emerged to counter old ones, though determining the relationship between media and audience views of stereotypes is complex.
