It's been 20+ years since researchers recommended that police videorecord lineups. But no one has empirically tested the diagnostic value of these videos... until now.
Here, we provide a compelling case to mandate the videorecording of lineup procedures.

Finding #3:
Witnesses' lineup behavior can diagnose high-confidence mistaken identifications. When witnesses are highly confident but their behavior indicates a weak and disfluent recognition experience, the CJS system should doubt their accuracy.

Finding #2:
Not only did witness behaviors discriminate between accurate and inaccurate decisions, but they also improved classification performance over and above confidence and decision speed.

Finding #1:
Accurate witnesses behaved markedly different than inaccurate witnesses—a strong and fluent recognition experience implied accuracy and a weak and disfluent recognition experience implied inaccuracy.

(3) Simultaneous lineups are superior to sequential lineups.

(2) that accurate witnesses’ justifications tended to reflect absolute language (e.g., “I recognized him”) and inaccurate witnesses’ justifications tended to reflect relative language (e.g., “He looks most like the person”).

We found that (1) using confidence, decision time, and the natural language witnesses expressed when justifying their lineup decision increased the potential to postdict accuracy
