Description
Kelly A Meiklejohn and colleagues run in 2026 a global interlaboratory study of a proposed standard for image source opinions in forensic work. Labs compare faces, hands, and clothing in photos, yet opinion scales vary widely. Twenty image pairs of varied source and difficulty were judged by 38 practitioners and 44 laypersons.
Practitioners agreed with each other more than laypersons did across all three image types. Practitioners also judged true source more accurately for face and hand pairs. With a clear five-step opinion guide, both groups reached moderate agreement and high accuracy overall.
