That is, Northern Ireland is believed to be both unique and unintelligible. This is paradoxical for two reasons. Sociologists have long sought to render Northern Ireland intelligible and to locate it in a comparative framework with similar societies elsewhere. They have done so to the point where, along with other social scientists, they have made it one of the world's most researched societies. In his book on contemporary Northern Irish society, Coulter describes it as proportionately the most studied place on the planet.
