Ostracism is a social phenomenon where an individual or group is deliberately excluded or ignored by others. This practice can occur in various settings, such as schools, workplaces, or communities, and can lead to feelings of isolation and distress for those affected. The term originates from ancient Greece, where citizens could vote to banish someone from the city-state for a period of time using pottery shards called ostraka. The effects of ostracism can be profound, impacting mental health and social relationships. Research shows that being ostracized can lead to anxiety, depression, and a decrease in self-esteem. Understanding the dynamics of ostracism is important for fostering inclusive environments and promoting positive social interactions.
