The goal of this study was to determine how varying witness information influenced jury verdicts for an individual identified in a photographic lineup. Participant-jurors (N = 145) read a criminal case and eyewitness testimony transcript before choosing a guilty or not guilty verdict for a selected individual. The witness’s quality of view, familiarity with the perpetrator, and neighbors’ input (hearsay) were manipulated. Identifications based on a facial view generated the same guilty rate as an identification based on culprit clothing or neighbor input. A witness with a very poor view received significantly less guilty verdicts. Verdict confidence did not differ significantly between conditions. Results suggest a lack of juror discriminability and potential bias to convict.
