The term that means showing prejudice toward an individual or group based on categories of characteristics is "discrimination."
Explanation
- Discrimination is defined as the unfair or prejudicial treatment of individuals or groups based on characteristics such as race, gender, age, religion, ethnicity, or other social categories. It involves actions taken due to prejudicial attitudes rather than just beliefs or feelings. It is the behavior or practice that results from prejudice toward specific groups or individuals.
- Prejudice itself refers to preconceived opinions or attitudes (usually negative) toward a person or group based on perceived characteristics. It is more about internal attitudes rather than acted behavior, while discrimination is the external expression or action based on those prejudices.
Therefore, showing prejudice and acting on it toward an individual or group based on their category of characteristics is best described by the term discrimination.
