Objectives: This field-simulation experiment was designed to compare eyewitness performance when conducting showups and lineups under field versus laboratory conditions. Hypotheses: We expected to replicate the findings from previous field-simulation experiments showing over-confidence in showup identifications made under field but not lab-conditio...


... Yet, more recent research focusing on both the potential to rule in guilty suspects and on the potential to rule out innocent suspects finds that showups are better at ruling out innocent suspects than are lineups (they have a better trade-off for correct rejections and misses). In fact, showups are so much more effective at ruling out innocent suspects that they have better overall discriminability than do lineups (Eisen et al., 2022;Starns et al., 2021). This creates a serious dilemma. ...
