Integrative complexity is a research psychometric that refers to the degree to which thinking and reasoning involve the recognition and integration of multiple perspectives and possibilities and their interrelated contingencies.[1]
Integrative complexity is a measure of the intellectual style used by individuals or groups in processing information, problem-solving, and decision making. Complexity looks at the structure of one's thoughts, while ignoring the contents. It is scorable from almost any verbal materials: written materials, such as books, articles, letters, and transcript; as well as audio-visual material.
The measure of integrative complexity has two components: differentiation and integration. Differentiation refers to the perception of different dimensions when considering an issue. Integration refers to the recognition of cognitive connections among differentiated dimensions or perspectives.[2]
In a 1988 study it was demonstrated that changes in Integrative Complexity could be potentially used in international violence prediction.[3] These findings were seen again a 1995 article by Guttieri, Wallace, and Suedfeld looking at the Cuban Missile Crisis.[4]
