The HIG Research Program is evaluating current practices and developing reliable, evidence-based approaches to improve investigators’ interrogation capabilities. All research conducted by the program is unclassified and completed under the oversight of Institutional Review Boards that ensure the protection of human subjects. Professionals, trainers, and researchers can now access the findings and products of this research program.
The training and practice of interrogation has been primarily based upon customary knowledge - developed over time through experience, handed-down through observation and story-telling, and ultimately codified in manuals, policies, and regulations. Over the past several decades, researchers have begun to assess the validity of the methods used by interrogation professionals, with the goal of applying scientific knowledge to improve the effectiveness of these practices – a perspective drawn from independent observation, theory driven and empirically derived, and founded upon the principles of replication and peer review. This What Works process offers a systematic review of the available scientific evidence to assess the effectiveness of a given approach.
The HIG Research Program has engaged a team of more than 30 researchers from academia, government, and the private sector from the United States, as well as countries in Europe, Africa, the Middle East, Southeast Asia, and Australia. Together, these researchers have produced more than 100 peer-reviewed publications, and have begun to translate their findings into recommendations for training and practice.
