Obstracism, often spelled as "ostracism," refers to the exclusion or rejection of an individual or group from social interactions or community activities. This social phenomenon can occur in various contexts, such as within families, workplaces, or peer groups, and can lead to significant emotional distress for those who are ostracized. It is often a form of social punishment used to enforce group norms or cohesion. The effects of ostracism can include feelings of loneliness, low self-esteem, and even mental health challenges.
