Island mentality refers to the notion of isolated communities perceiving themselves as superior or exceptional to the rest of the world. This term does not directly refer to a geographically confined society, but to the cultural, moral, or ideological superiority of a community lacking social exposure. Island mentality can be characterized by narrow-mindedness, ignorance, or outright hostility towards any artifact (concept, ideology, lifestyle choice, art form, etc.) originating from outside of the geographic area inhabited by the society.
The term "island mentality" is also used in some psychological research[which?] to describe individuals who dislike or have problems with relating to others, and then live as loners or "islands". This concept (in which people may feel inferior, afraid, or alone) has little to nothing to do with the above terminology.
