This book fills a gap in intelligence studies by setting out a new analytic methodology: analysis by contrasting narratives (ACN). This states that defining an enemy and attempting to counter threats can contribute to the possiblity of that threat manifesting. Peter de Werd applies ACN to the problem the US faced in understanding and responding to the phenomenon of Al Qaeda in the 1990s. He demonstrates how this approach can fill a gap in intelligence studies by enhancing our understanding of complex intelligence problems and strengthening the practice of intelligence analysis. Adopting a critical reflexivist theoretical stance, the book underlines the importance of an integrated approach to interpretation and action, and of a continuous dialogue between intelligence and policy.
