Interview and interrogation methods and their effects on true and false confessions

Abstract

The interviewing and interrogation of suspects can be particularly important to securing convictions against the guilty and freeing the wrongly accused. There are two general methods of questioning suspects: information-gathering and accusatorial. The information-gathering approach, used in the United Kingdom, New Zealand, Australia, and elsewhere, as more generally in Western Europe, is characterized by rapport-building, truth-seeking, and active listening. The accusatorial approach, used primarily in the United States and Canada, is characterized by accusation, confrontation, psychological manipulation, and the disallowing of denials. Which method is more effective has become a hotly debated topic as the number of false confessions identified continues to rise. Our objective was to systematically and comprehensively review published and non-published, experimental and observational studies on the effectiveness of interviewing and interrogation methods. We focus on the questioning of suspects using information-gathering and accusatorial methods seeking to elicit confessions.
