The U.S. Supreme Court, state courts, and social science researchers have stated that showup identifications (one-person identifications) are less reliable than lineup identifications. Moreover, 74 % of eyewitness experts endorsed false identifications as more likely to occur from showups than lineups. Examination of the extant literature and receiver operating characteristic (ROC) analyses of over 7500 participants confirm that showups are an inferior procedure to lineups. This conclusion holds true even in situations where showups should have a memorial advantage (e.g., at a short retention interval, a clothing match between encoding and test). A signal-detection-based diagnostic-feature model provides a theoretical explanation for why showups produce inferior eyewitness performance. The data also reveal that confidence is better related to accuracy for lineups than for showups. Unless new procedural enhancements can be developed that enhance reliability, police should refrain from conducting showups in favor of lineups.

Research on primary confessions has demonstrated that it is a powerful form of evidence. The goal of the current research was to investigate whether secondary confessions – the suspect confesses to another individual who in turn then reports the confession to the police – could be as persuasive. In Experiments 1 and 2, participants read a murder trial containing an eyewitness identification, a secondary confession, and character testimony, and made midtrial assessments of the evidence. Results indicated that the secondary confession was evaluated as the most incriminating. In Experiment 3, participants read summaries of four criminal trials, each of which contained a primary confession, a secondary confession, eyewitness identification, or none of the above. The two confession conditions produced significantly higher conviction rates. Our findings suggest that secondary confessions are another powerful and potentially dangerous form of evidence.

Feedback provided to eyewitnesses can influence memory as to how confident their previous line-up selections were. Witnesses given confirming feedback remember being more confident than witnesses who are told their selection was incorrect regardless of their accuracy. This can have a powerful impact on judges and juries. In this article, we examine the effect of feedback from a ‘snitch’ (a jailhouse informant). This manipulation often occurs in real cases, despite that fact that snitches could have something to gain from providing information to police. Our participants witnessed a staged crime and then identified the perpetrator from a target-absent line-up. Two days later, participants were provided with feedback and were probed for confidence. Results show that confirming feedback from a snitch has the same effect as a confession made by the actual suspect, and disconfirming feedback reduces confidence. Implications and relation to the extant literature on eyewitness confidence are discussed.
