Integrative complexity

Integrative complexity is a research psychology measure designed to quantify the complexity of written texts based on dimensions of integration and differentiation.

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: books, articles, fiction, letters, speeches and speech transcripts, video and audio tapes, and interviews.

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.
