Final answer:
Groups with negative desirability are known as dissociative reference groups, which are groups whose values and beliefs an individual actively rejects.
Step-by-step explanation:
Groups with negative desirability are referred to as dissociative reference groups. A dissociative reference group is a group with which an individual does not want to associate, and its values and norms are often considered undesirable or are rejected by the individual. This concept contrasts with a reference group, which is a group that individuals use as a standard for evaluating themselves and their own behavior. Reference groups can include family, peers, sports teams, or any group whose norms and values influence an individual's behavior.
