In 2013, researchers, psychologists, and scholars began research on interrogation, and suspect interviews. Their primary goal was to collect data regarding interrogation and interview techniques. Using a taxonomy development method, psychologists and researchers broke down 804 interrogation techniques into 71 interrogation techniques by eliminating broad categories, or non-meaningful methods of interrogation. After identifying the 71 interrogation techniques, they classified them into six interrogation domains: rapport and relationship building, context manipulation, emotion provocation, collaboration, confrontation/competition, and presentation of evidence. These six interrogation domains are based on what is mostly used by interrogators to elicit information and confessions from uncooperative suspects.
