Final answer:
Prejudice is a negative evaluation of a group based on stereotypes and assumptions, ignoring individual characteristics. It involves making judgments without considering the differences among individuals in the group.
Step-by-step explanation:
The term that defines a negative evaluation of a group, typically based on unfavorable (and often wrong) stereotypes about the group, is prejudice. Prejudice is a negative attitude and feeling toward an individual based solely on their membership in a particular social group. It involves making assumptions and generalizations about a group without considering individual characteristics or differences. For example, a stereotype about older adults being slow and incompetent can lead to prejudice against all older adults, even though many individuals in this group may be spry and intelligent.
