This article provides an annotated review essay of Jennifer E. Sims’ book, Decision Advantage (2022). She communicates several valuable insights into how intelligence manifests in international affairs. Qualities are accomplished through Sims’ development of the concept and theory of ‘decision advantage’ in a variety of intelligence contexts, articulated via a series of different historical case studies ranging chronologically from the Spanish Armada to Cyberwar. Alongside acknowledging intelligence systems and engineering, notions of ‘intelligence power’ and ‘intelligence advantage(s)’ emerge as central, together with ideas of agility and adaptability amongst exponents. While undeniably forming a useful start, what Sims’ work ultimately discloses has rich potential for being taken yet further. Her insights readily extend into other closely connected domains, such as into more widely-ranging ‘pluralistic’ and ‘globalised’ realms of research to practitioner interest. Those areas are also found today in Intelligence Studies, and especially when Intelligence is evaluated most internationally.
