Evidence disclosure strategies in suspect interviewing


Evidence disclosure strategies in suspect interviewing

The Strategic use of Evidence (SUE) technique is an interview method for enhancing and eliciting verbal cues to deception. Prior research on the SUE-technique has demonstrated that late disclosure (i.e., the evidence is presented after having collected the suspect’s account) is more effective than early disclosure (evidence is disclosed before having collected the subject’s account). The rationale is that if subjects remain unaware of the evidence against them, then lying (vs. truthful) subjects are more likely to withhold critical details, and will thereby provide accounts that contradicts existing evidence (Hartwig, Granhag, & Luke, 2014). The SUE approach has recently been modified to elicit the subject’s forthcomingness and to increase admissions.

Type of research

The current project will develop new strategic approaches for disclosing evidence to suspect to affect the interview outcome. These strategies will be examined in behavioral experiments.
