Ostracism is the social practice of excluding or ignoring an individual or group from a community or society. This can occur in various settings, such as schools, workplaces, or social groups, and often leads to feelings of loneliness and isolation for those affected. The term originates from ancient Greece, where citizens could vote to banish someone from the city for a period of time. The effects of ostracism can be profound, impacting mental health and well-being. Research shows that individuals who experience ostracism may suffer from anxiety, depression, and low self-esteem. Understanding the dynamics of ostracism is important for fostering inclusive environments and promoting social cohesion within communities.
