Final answer:
Ostracism is linked to an increase in aggression, potentially as a response to the anger and frustration felt by the ostracized individual.
Step-by-step explanation:
Ostracism has been observed to intensify aggression. When individuals are ostracized, they may experience heightened feelings of anger and frustration, which can lead to aggressive behavior as a form of expression or retaliation. Instances of deindividuation, where a person may feel a sense of anonymity within a group, are often associated with aggressive behavior, though research has shown inconsistent results on the role it plays. This context, along with an understanding of social influences such as group polarization, homophily, and groupthink, can contribute to our understanding of the relationship between ostracism and aggression.
