ORBIT is an evidence-based approach to the analysis & training for interviewing high-value detainees by law enforcement, security services, & the military. Although its origins go as far back as 2005, it gained considerable traction after 2012, when the High-Value Detainee Interrogation Group, formed by the Obama Administration in the US, funded work for assessment of its application in the context of interviews with high-value targets. Since then, the authors have collected the largest corpus of data anywhere in the world on real suspect interviews with terrorist detainees. This text shows what they found - that rapport-based methods work & that coercion, persuasion, & threats do not. Outlining the development of their own unique stance on rapport & its influences drawn from humanistic psychology, the authors show, through real-life examples, the reasons why compassion & understanding work in interrogation.
