Answer:
American Sociologist Herbert Blumer argued that prejudice is activated when groups feel that they are threatened by other groups they see as beneath them.
Explanation:
According to the studies of Herbert Blumer, the dominant group within racial prejudice has a sense of superiority over the other group or groups. The dominant group sees others as foreign, and believes it is entitled to privileges and advantages related to race. When the outgroups, or subordinate groups, grow in numbers, for instance, the dominant group feels threatened, activating their prejudice against the others.
