the jaggedness principle. This principle holds that we cannot apply one-dimensional thinking to understand something that is complex and “jagged.” What, precisely, is jaggedness? A quality is jagged if it meets two criteria. First, it must consist of multiple dimensions. Second, these dimensions must be weakly related to one another. Jaggedness is not just about human size; almost every human characteristic that we care about—including talent, intelligence, character, creativity, and so on—is jagged.
