Scapegoating

Scapegoating (from the verb "to ") is the practice of singling out any party for unmerited negative treatment or blame as a scapegoat. Scapegoating may be conducted by individuals against individuals (e.g. "he did it, not me!"), individuals against groups (e.g., "I couldn't see anything because of all the tall people"), groups against individuals (e.g., "Jane was the reason our team didn't win"), and groups against groups.

A scapegoat may be an adult, child, sibling, employee, peer, ethnic, political or religious group, or country. A whipping boy, identified patient or "fall guy" are forms of scapegoat.

A medical definition of scapegoating is:

Scapegoating is a tactic often employed to characterize an entire group of individuals according to the unethical or immoral conduct of a small number of individuals belonging to that group. Scapegoating relates to guilt by association and stereotyping.

Scapegoated groups throughout history have included almost every imaginable group of people: genders, religions, people of different races, nations, or sexual orientations, people with different political beliefs, or people differing in behaviour from the majority. However, scapegoating may also be applied to organizations, such as governments, corporations, or various political groups.

Unwanted thoughts and feelings can be unconsciously projected onto another who becomes a scapegoat for one's own problems. This concept can be extended to projection by groups. In this case the chosen individual, or group, becomes the scapegoat for the group's problems. "Political agitation in all countries is full of such projections, just as much as the backyard gossip of little groups and individuals." Swiss psychiatrist Carl Jung considered indeed that "there must be some people who behave in the wrong way; they act as scapegoats and objects of interest for the normal ones".

The scapegoat theory of intergroup conflict provides an explanation for the correlation between times of relative economic despair and increases in prejudice and violence toward outgroups. Studies of anti-black violence in the southern US between 1882 and 1930 show a correlation between poor economic conditions and outbreaks of violence (e.g., lynchings) against blacks. The correlation between the price of cotton (the principal product of the area at that time) and the number of lynchings of black men by whites ranged from -0.63 to -0.72, suggesting that a poor economy induced white people to take out their frustrations by attacking an outgroup.
