The goal of Reasoning for Intelligence Analysts is to address the three distinct dimensions of an analyst's thinking: the person of the analyst (their traits), the processes they use (their techniques), and the problems they face (their targets). Based on a decade of academic research and university teaching in a program for aspiring intelligence analysts, this multidimensional approach will help the reader move beyond the traditional boundaries of accumulating knowledge or critical thinking with techniques to assess the unique targets of reasoning in the information age. This approach is not just a set of techniques, but covers all elements of reasoning by discussing the personal, procedural, and problem-specific aspects. It also addresses key challenges, such as uncertain data, irrelevant or misleading information, indeterminate outcomes, and significance for clients through an extensive examination of hypothesis development, causal analysis, futures exploration, and strategy assessment. Both critical and creative thinking, which are essential to reasoning in intelligence, are integrated throughout. Structured around independently readable chapters, this text offers a systematic approach to reasoning a long with an extensive toolkit that will serve the needs of both students and intelligence professionals.
