While research on interrogation has traditionally focused on problematic practices that lead to false confessions, more recent research has addressed the need to develop scientifically validated techniques that lead to accurate information from both suspects and sources. In the present review, we summarize this recent research on building and maintaining rapport, eliciting information, presenting evidence, and assessing credibility. Research is described in the context of accusatorial (guilt-presumptive and psychologically manipulative) versus information-gathering (cooperative and evidence based) approaches to interviewing and interrogation. We also suggest future directions for research to continue to improve the efficacy of interviews and interrogations.
