Competent investigative interviewing skills are key to securing reliable information from victims, witnesses, informants, and suspects. Information obtained in interviews often plays an important role in directing an investigation, informing effective decision-making, promoting efficient allocation of resources, as well as securing reliable prosecutions and mitigating risk of miscarriages of justice. However, effective investigative interviewing is a complex skill to master; demanding a sound understanding of the many cognitive, social, and environmental factors that influence the content and accuracy of witness and suspect accounts. To ensure that investigative interviewing and intelligence gathering produces usable, credible, and reliable information in an effective and ethically defensible manner, training and practice must be evidence-based. This short article outlines how practitioners, trainers and policy makers can navigate the best available research evidence to evaluate ‘what works?’ in investigative interviewing.
