Siege mentality

In sociology, siege mentality is a shared feeling of victimization and defensiveness—a term derived from the actual experience of military defences of real sieges. It is a collective state of mind in which a group of people believe themselves constantly attacked, oppressed, or isolated in the face of the negative intentions of the rest of the world. Although a group phenomenon, the term describes both the emotions and thoughts of the group as a whole, and as individuals.

The result is a state of being overly fearful of surrounding peoples, and an intractably defensive attitude.

The related term bunker mentality may be used in the context of businesses facing competition or downsizing, with a similar paradigm applying to some religious groups.

Characteristics
Among the consequences of a siege mentality are black and white thinking, social conformity, and lack of trust, but also a preparedness for the worst and a strong sense of social cohesion.

Examples
Historically, siege mentalities existed in the Soviet Union, Communist People's Socialist Republic of Albania, Rhodesia, Apartheid South Africa, and Northern Ireland during The Troubles, as a result of ideological or political isolation.

In the present day, siege mentalities have also been described with regards to countries such as Israel and North Korea; in the latter it is arguably encouraged by the government to help justify their continuance in power. Further contemporary examples of states in which a siege mentality is prevalent may include Turkish Republic of Northern Cyprus, Republic of China, Venezuela, Poland and Cuba.

Within the United States, the siege mentality has been used to conservative Southerners following the American Civil War, and later on the Southern Strategy and supporters of Donald Trump, especially towards the federal government. The politics of U.S. Evangelicals in particular were cited by the New York Times in 2017 as reflecting a siege mentality.

Sociologically, the term may refer to persecution feelings by anyone in a group that views itself as a threatened minority, as with the early psychoanalysts. This can be used for example in the field of sports, where coaches or managers often create a siege mentality in their players by highlighting an environment of hostility from outside the club (whether the hostility is real or exaggerated is irrelevant).

Siege mentalities are particularly common in business, the result of competition or downsizing, though here the (smaller-scale) alternative of "bunker mentality" (analogous to soldiers who have taken shelter in a bunker) may be used. Some religious groups may have this paradigm, particularly if they are not traditional mainstream groups.

Literary analogies
Seamus Heaney used the phrase "Besieged within the siege" to describe the feeling of the beleaguered Catholic minority in Northern Ireland within the broader siege mentality of the Protestant community itself.
