Wells (1984) hypothesized that simultaneous lineups encourage participant/witnesses to use a relative judgment strategy, comparing lineup members one to another to determine which of them most resembles the culprit. He argued that if the innocent suspect in a culprit-absent lineup resembles the culprit, the relative judgment strategy will foster mistaken identifications. Empirical support for that claim has hitherto been correlational. In four experiments (three completed, N = 472, one ongoing), participants watched videos of fictional crimes and were instructed to use either an absolute or a relative strategy on subsequent lineups. Judgment strategy did not appear to influence lineup performance.
