How Analysts Think

In this paper we present our observations of how seven criminal intelligence analysts use inference making and storytelling to create explanations. Adapting the Critical Decision Method, we observe they engage in a process of anchoring to gain traction and initiate further inquires; they engage in a laddering process, where they develop explanations to extend or elaborate their ideas that create bridges to new understanding; and they complement their anchoring and laddering activities by associative questioning to discover what other associations exists. These un-intended associations can lead to insights, or generate new patterns recognisable by intuition. We envisage a better understanding of how analyst think and reason might help design software that encourages insight.
