Evaluating lay testimony is important in both civil and criminal justice. For example, whether a witness is reliable can make the difference between conviction and acquittal of a defendant, or a person being granted leave to remain rather than facing deportation. However, It is difficult to determine accurately whether a person providing testimony is being truthful and is likely to be accurate in their assessments.
We are working on a large-scale evaluation of testimony evaluation, that examines the basic science of testimony evaluation and translates scientific research into practical and normatively appropriate legal procedure and best-practice guidelines.
