Description
Shunning can be the act of social rejection, or mental rejection. Social rejection is when a person or group deliberately avoids association with, and habitually keeps away from an individual or group. This can be a formal decision by a group, or a less formal group action which will spread to all members of the group as a form of solidarity. It is a sanction against association, often associated with religious groups and other tightly knit organizations and communities. Targets of shunning can include persons who have been labeled as, apostates, whistleblowers, dissidents, scabs, or anyone the group perceives as a threat or source of conflict. Social rejection has been established to cause psychological damage and has been categorized as torture. Mental rejection is a more individual action, where a person subconsciously or willfully ignores an idea, or a set of information related to particular viewpoint. Some groups are made up of people who shun the same ideas.
Social rejection was and is a punishment used by many customary legal systems. Such sanctions include the ostracism of ancient Athens and the still-used kasepekang in Balinese society.
Stealth shunning is a practice where a person or an action is silently banned. When a person is silently banned, the group they have been banned from doesn't interact with them. This can be done by secretly announcing the policy to all except the banned individual, or it can happen informally when all people in a group or email list each conclude that they do not want to interact with the person. When an action is silently banned, requests for that action are either ignored or turned down with faked explanations
Shunning contains aspects of what is known as relational aggression in psychological literature. When used by church members and member-spouse parents against excommunicant parents it contains elements of what psychologists call parental alienation. Extreme shunning may cause traumas to the shunned (and to their dependents) similar to what is studied in the psychology of torture.
